Description

FIELD OF THE INVENTION

The present invention relates to a radiation panel structure and an air conditioner.

RELATED ART

Convection type air conditioners are frequently used that adjust the temperature of a room by blowing out temperature adjusted air into a room. A convection type air conditioner is normally provided with an outlet through which passes the air blown out into the room. This outlet is, for example, an opening provided at the front surface lower part of the indoor unit along the longitudinal direction of an indoor unit of the air conditioner. The convection type air conditioner blows the temperature adjusted air from the outlet out into the room, and produces a convection of temperature adjusted air in the room. Thereby, the temperature adjusted air can be made to reach a large area of the room, thus enabling the room temperature to be adjusted (refer to Japanese Published Patent Application No. 2001-41488).

However, with the convection type air conditioner of the type mentioned above, there is a risk that a draft will be generated. Namely, with a convection type air conditioner, the convection of air blown out from the outlet easily and directly contacts the occupants and the like in the room, and there is consequently a risk that the occupants and the like will feel uncomfortable.

DISCLOSURE OF THE INVENTION

It is an object of the present invention to provide a radiation panel structure and an air conditioner capable of reducing discomfort caused by drafts.

A radiation panel structure as recited in Claim 1 comprises an air intake part and a pressure generating space component. The air intake part takes in temperature adjusted air. The pressure generating space component constitutes a pressure generating space wherein the air generates a pressure larger than atmospheric pressure. Further, at least a first part of the pressure generating space component is made of a porous material having a prescribed radiation rate. Furthermore, from the viewpoint of temperature adjustment by radiation, it is preferable that the radiation rate of the first part be 0.6 or greater.

With this radiation panel structure, the temperature of the first part of the pressure generating space is adjusted by the temperature adjusted air. Further, the first part is made of a porous material having a prescribed radiation rate. Consequently, this radiation panel structure can perform temperature adjustment of the room by the radiation from the first part that used the temperature of the air in the pressure generating space. In addition, the temperature adjusted air generates a pressure in the pressure generating space larger than atmospheric pressure. Accordingly, temperature adjusted air is gently blown out from the plurality of holes in the first part into the room. Consequently, this radiation panel structure can perform temperature adjustment of the room by the air gently blown out from the first part.

Thus, with this radiation panel structure, temperature adjustment of the room can be performed by radiation and by gentle blow out of air. Consequently, with this radiation panel structure, discomfort caused by drafts can be reduced.

A radiation panel structure as recited in Claim 2 is a radiation panel structure as recited in Claim 1, wherein the first part is made of a fiber material having a prescribed radiation rate.

With this radiation panel structure, the temperature of the first part of the pressure generating space is adjusted by the temperature adjusted air. Furthermore, the first part is made of a fiber material having a prescribed radiation rate. Consequently, this radiation panel structure can perform temperature adjustment of the room by the radiation from the first part that used the temperature of the air in the pressure generating space. In addition, the temperature adjusted air generates a pressure in the pressure generating space greater than atmospheric pressure. Accordingly, temperature adjusted air is gently blown out from the gaps in the weave of the first part into the room. Consequently, this radiation panel structure can perform temperature adjustment of the room by the air gently blown out from the first part.

Thus, with this radiation panel structure, temperature adjustment of the room can be performed by radiation and by the gentle blow out of air. Consequently, with this radiation panel structure, discomfort caused by drafts can be reduced.

A radiation panel structure as recited in Claim 3 is a radiation panel structure as recited in Claim 1 or Claim 2, wherein the pressure generating space component comprises a second part opposing the first part, and further comprising a shape supporting member. The shape supporting member, with one end fixed to the first part and the other end fixed to the second part, supports the shape of the pressure generating space component.

Because the fiber material is flexible, if a pressure greater than atmospheric pressure is generated in the pressure generating space, there is a risk that the first part made of the fiber material and the second part opposing the first part will bulge, and the prescribed shape will not be maintained.

With this radiation panel structure, the distance between the first part and the second part is maintained by the shape supporting member. Consequently, with this radiation panel structure, bulging of the flexible first part and second part is suppressed, and their shapes can be maintained.

A radiation panel structure as recited in Claim 4 is a radiation panel structure as recited in Claim 3, comprising a plurality of the shape supporting members disposed spaced apart.

This radiation panel structure comprises a plurality of shape supporting members disposed spaced apart. Consequently, by disposing a plurality of shape supporting members spaced apart, the first part, which attempts to bulge due to the pressure, can be maintained in an arbitrary shape.

A radiation panel structure as recited in Claim 5 is a radiation panel structure as recited in any one claim of Claim 2 through Claim 4, wherein the coarseness of the weave of the first part differs by portion.

With this radiation panel structure, the coarseness of the weave of the first part differs by portion, and the wind speed of the air blown out from the gaps in the fiber consequently differs by portion. Accordingly, the reaction force generated differs by portion due to the differences in the wind speed of the blown out air. In addition, because the first part is flexible, it is deformed by the reaction force of the blow out. Consequently, with this radiation panel structure, a deformation is generated that differs by the portion of the first part, and an irregular pattern can therefore be created in the surface of the first part. Thereby, the aesthetics of the radiation panel structure can be enhanced.

A radiation panel structure as recited in Claim 6 is a radiation panel structure as recited in any one claim of Claim 2 through Claim 5, wherein the first part is capable of collecting undesirable substances included in the air that passes through gaps in the fiber.

With this radiation panel structure, undesirable substances, such as dust, viruses, and pollen, can be collected by the weave. Accordingly, air in which undesirable substances have been reduced can be blown out from the first part into the room. Consequently, with this radiation panel structure, the air in the room can be cleanly maintained.

A radiation panel structure as recited in Claim 7 is a radiation panel structure as recited in any one claim of Claim 2 through Claim 6, wherein the first part contains an active ingredient that reduces unpleasant substances included in the air that passes between the fibers.

With this radiation panel structure, unpleasant substances included in the air that passes between the fibers can be reduced by the active ingredient possessed by the first part. For example, by adding a deodorizer, a bactericide, and the like, to the first part, the air sent into the room can be deodorized and disinfected. Consequently, air in which unpleasant substances have been reduced can be blown out from the first part into the room. Thereby, with this radiation panel structure, the comfort of the occupants and the like in the room can be enhanced.

A radiation panel structure as recited in Claim 8 is a radiation panel structure as recited in any one claim of Claim 1 through Claim 7 attached to a separate convection type air conditioner. The convection type air conditioner performs temperature adjustment of the air and blows out the temperature adjusted air. Further, the air intake part is connected to the convection type air conditioner.

With this radiation panel structure, the air intake part can be connected to a separate convection type air conditioner. Consequently, this radiation panel structure can be attached to an existing convection type air conditioner. Accordingly, with this radiation panel structure, an existing convection type air conditioner can be effectively utilized.

A radiation panel structure as recited in Claim 9 is a radiation panel structure as recited in any one claim of Claim 1 through Claim 8, wherein the pressure generating space component comprises a flexible material, and further comprises a modifying part.

The indoor unit casing 21 a internally houses the indoor heat exchanger 22, the indoor fan 23, and the like, and comprises an inlet 26a and a connection port 27a (ventilation port). The inlet 26a is an opening through which passes the air taken in from the room into the indoor unit casing 21a. The connection port 27a is an opening through which passes air sent from inside the indoor unit casing 21 a through the indoor heat exchanger 22 to the radiation panel structure 5a, and is connected to an air intake 51 of the radiation panel structure 5a, which is discussed later.

The indoor heat exchanger 22 is connected via a refrigerant piping 4 to the outdoor heat exchanger, the compressor 31, and the like. The indoor heat exchanger 22 adjusts the air temperature by exchanging heat with the air that passes therethrough.

The indoor fan motor 24 rotatably drives the indoor fan 23, which generates an air current that is taken in from the room and sent to the radiation panel structure 5a. This air current is a current of air that is taken in from the inlet 26a into the indoor unit casing 21a, passes through the indoor heat exchanger 22, the connection port 27a, and the air intake 51, and arrives inside the radiation panel structure 5a.

The indoor unit temperature sensor 25 includes various temperature sensors that detect the temperature of the indoor heat exchanger, the temperature of the indoor air, and the like.

The radiation panel structure 5a is disposed in the vicinity of the ceiling surface, and performs air conditioning, such as heating and cooling, by radiation using the temperature of the temperature adjusted air, and by blowing out the temperature adjusted air. The constitution of the radiation panel structure 5a will be discussed later in detail.

In addition, the air conditioner 1a comprises a control unit 6 (a first control unit and a second control unit). The control unit 6 is disposed split between the outdoor unit 3 and the indoor unit 2a, and controls the operation of the air conditioner 1a. The control unit 6 is connected to components such as the compressor 31, the four-way switching valve 32 , the motor operated valve 33, the outdoor fan motor 34, the outdoor unit temperature sensor 35, the indoor fan motor 24, the indoor unit temperature sensor 25, and the like, as depicted in FIG. 4. If the control unit 6 receives an operation command from a remote control 7, then it controls the operation of the air conditioner 1a by controlling the various components.

<CONSTITUTION OF THE RADIATION PANEL STRUCTURE>

FIG. 2 depicts an external view of the radiation panel structure 5a.

The radiation panel structure 5a has a thin, plate shaped external form, and is flatly shaped. In addition, the radiation panel structure 5a is disposed in the vicinity of the ceiling surface and parallel to the ceiling surface. Consequently, with respect to the living space below, the radiation panel structure 5a has a projected area that is larger than in other directions. The radiation panel structure 5a comprises the air intake 51, a radiation part 52a (pressure generating space component), a plurality of shape supporting members 53a, and the like.

The air intake 51 is the portion where the temperature adjusted air is taken in, and is an opening provided on one of the side surfaces of the radiation panel structure 5a. The air intake 51 is detachably connected to the connection port 27a of the indoor unit casing 21a, and the air sent by the indoor fan 23 (refer to the outline arrow A1) passes therethrough.

The radiation part 52a comprises a first radiation surface 54 (first part), a second radiation surface 55 (second part), and three side surfaces 56, and internally constitutes a pressure generating space PS wherein a pressure greater than the atmospheric pressure is generated by the air.

The first radiation surface 54 has a quadrilateral, thin, sheet shape, and closes the lower part of the pressure generating space PS. The first radiation surface 54 is disposed parallel to the ceiling surface at a position facing the living space of the room. In addition, the first radiation surface 54 is made of a woven fabric having a radiation rate of approximately 0.9.

The second radiation surface 55 is shaped the same as the first radiation surface 54, and closes the upper part of the pressure generating space PS. The second radiation surface 55 is disposed opposing the first radiation surface 54 at a position facing the ceiling surface. Namely, the second radiation surface 55 is disposed between the first radiation surface 54 and the ceiling surface. In addition, the second radiation surface 55 is made of a woven fabric the same as the first radiation surface 54.

The three side surfaces 56 each have a long rectangular shape, and close the side parts of the pressure generating space PS, excluding the air intake 51. The three side surfaces 56 are respectively connected to the three sides of the first radiation surface 54 and the three sides of the second radiation surface 55. In addition, the three side surfaces 56 are made of a woven fabric the same as the first radiation surface 54 and the second radiation surface 55.

Thus, excepting the air intake 51, the radiation panel structure 5a has a closed bag shape.

The plurality of shape supporting members 53a are thread shaped members disposed spaced apart. Each of the plurality of shape supporting members 53a is the same length, with one end fixed to the first radiation surface 54, and the other end fixed to the second radiation surface 55. The plurality of shape supporting members 53a is disposed substantially evenly on the flat surfaces of the first radiation surface 54 and the second radiation surface 55. If a pressure greater than the atmospheric pressure is generated in the pressure generating space PS, then the shape supporting members 53a maintain the first radiation surface 54 and the second radiation surface 55 as flat shapes, thereby maintaining the radiation part 52a as a plate shape. Furthermore, symbols are affixed only to one of the shape supporting members 53a in FIG. 2, and are omitted from the other shape supporting members 53a.

<OPERATION OF THE AIR CONDITIONER>

The following explains the operation for the case where this air conditioner 1a air conditions a room.

During cooling operation, the indoor heat exchanger 22 functions as an evaporator, and captures the heat from the air passing therethrough. The heat from the air in the room taken in by the indoor fan 23 from the inlet 26a into the indoor unit casing 21a is captured when it passes through the indoor heat exchanger 22, and is thereby cooled.

As depicted in FIG. 3, this cooled air passes through the connection port 27a and the air intake 51, and is sent to the pressure generating space PS inside the radiation part 52a. When the air is sent to the pressure generating space PS, a positive static pressure greater than the atmospheric pressure is generated in the pressure generating space PS. Namely, a pressure greater than the atmospheric pressure is generated in a direction perpendicular to the current of air flowing parallel to the ceiling surface (refer to the solid arrow A2). Consequently, the cooled air is pushed out from the gaps between the fibers of the woven fabric of the radiation part 52a, and gently blown out into the room (refer to the solid arrow A3).

In addition, the radiation part 52a is cooled by making contacting with the cooled air. Consequently, cold radiation is generated by the radiation part 52a (refer to the broken arrow A4).

Thus, when air is gently blown out from the gaps between the fibers of the radiation part 52a with this air conditioner 1a, the room is cooled by the cold radiation of the radiation part 52a.

During heating operation, the indoor heat exchanger 22 functions as a condenser, and heats the air passing therethrough. The heated air is sent to the pressure generating space PS inside the radiation part 52a, the same as during cooling operation. Further, the heated air is pushed out from between the fibers of the woven fabric, and gently blown out into the room. In addition, the radiation part 52a is heated by making contacting with the heated air. Further, heat radiation is generated by the radiation part 52a. Thus, when air is gently blown out from between the gaps of the fibers of the radiation part 52a with this air conditioner 1a, the room is heated by the heat radiation of the radiation part 52a.

<CHARACTERISTICS <1>

In the case of a convection type air conditioner that blows out temperature adjusted air directly into the room, there is a tendency for so-called drafts to be generated, wherein the blown out air directly impinges the occupants and the like. If such a draft is generated, then the occupants and the like often feel uncomfortable. In addition, even if the room temperature is adjusted by the blow out of the air, there is a risk that the draft will degrade the sensible temperature of the occupants and the like.

With this air conditioner 1a, the room can be cooled and heated by radiation and the gentle blow out of air, as described above. Consequently, the discomfort caused by drafts can be eliminated.

<2>

In the case of the convection type air conditioners used frequently in the past, there is a risk that large temperature differentials will be generated from place to place inside the room. Namely, a temperature differential tends to be generated between a place that the blown out air easily reaches and a place that it is difficult for the blown out air to reach. If large temperature differentials are generated from place to place, then the differences in the comfort level by place will increase greatly. In addition, there is also a risk that a large temperature differential will be generated in the height direction in the room.

By increasing the surface area of the first radiation surface 54 with this air conditioner 1a, it is possible to radiate and to gently blow out air from the vicinity of the ceiling surface toward a large area of the living space of the room. Consequently, the entire room can be heated or cooled substantially evenly. Thereby, it is possible to prevent the generation of an uncomfortable temperature differential between places in the room. Accordingly, the discomfort of the occupants and the like can be eliminated with this air conditioner 1a. In addition, even if there are a plurality of occupants and the like in the room, it is possible to generate a comfortable temperature environment for many occupants and the like.

Conversely, it is also possible to partially change the temperature environment of the room by changing the surface area of the first radiation surface 54. Further, by generating a temperature environment in the room desired by the occupants and the like, it is possible to further enhance the comfort of the occupants and the like.

Furthermore, the radiation panel structure 5a is disposed in the vicinity of the ceiling surface, and has a thin, plate shape. Consequently, even if the surface area of the first radiation surface 54 facing the living space is made relatively large, there is little risk of it interfering with the occupants and the like.

<3>

This air conditioner 1a performs both heating and cooling by radiation and heating and cooling by blowing out. Consequently, the convection performance by blowing out can be reduced more than the case wherein heating and cooling of the room is performed only by blowing out.

<4>

Conventional air conditioners that perform air conditioning by radiation often use a metal radiation panel having a high radiation rate.

With this air conditioner 1a, the radiation part 52a is made of a woven fabric, which has a radiation rate of approximately 0.9. Consequently, even though it is a woven fabric, the heating and cooling of the room by radiation can be performed with sufficient effectiveness.

In addition, the air blown out from the gaps between the fibers of the woven fabric make the temperature up to the outer side of the first radiation surface 54 the same as the temperature inside the radiation part 52a. Consequently, the heating and cooling of the room by radiation can be performed efficiently.

<5>

Because woven fabric is flexible, the radiation part 52a, which is made of woven fabric, tends to bulge and approach a cylindrical shape if a pressure greater than the atmospheric pressure is generated in the pressure generating space PS. In this case, there is a risk that the flat shape of the abovementioned type of radiation part 52a will not be maintained.

However, with the radiation panel structure 5a of this air conditioner 1a, the distance between the first radiation surface 54 and the second radiation surface 55 is maintained by the shape supporting members 53a. Consequently, bulging of the flexible first radiation surface 54 and second radiation surface 55 is suppressed, and their flat shapes can be maintained.

In addition, with the radiation panel structure 5a of this air conditioner 1a, the plurality of shape supporting members 53a is provided substantially evenly on the flat surfaces of the first radiation surface 54 and the second radiation surface 55. Consequently, the flat shape of the radiation part 52a can be maintained with greater precision.

Furthermore, the abovementioned shape supporting members 53a are thread shaped members, but may be strip shaped members or rigid, pole shaped members, and can achieve the effect of holding the shape of the radiation part 52a. However, in order for the radiation panel structure 5a to achieve this effect based on the flexibility of a woven fabric, it is preferable that the shape supporting members 53a are made of a thread shaped flexible material.

<6>

With this air conditioner 1a, the radiation panel structure 5a is detachably attached to the connection port 27a of the indoor unit casing 21a. Consequently, it is easy to detach and reattach the radiation panel structure 5a from and to the indoor unit casing 21a. Accordingly, the installation work and the maintenance of the radiation panel structure 5a are easy.

In addition, the radiation part 52a is made of a woven fabric. Consequently, if dirt adheres to the radiation part 52a, then it can be cleaned by detaching the radiation panel structure 5a.

<SECOND EMBODIMENT> <CONSTITUTION>

FIG. 5(b) depicts a side view of a radiation panel structure 5b according to the second embodiment of the present invention.

This radiation panel structure 5b comprises a plurality of shape supporting members 53b, the same as the radiation panel structure 5a according to the first embodiment. In the first embodiment, each of the plurality of shape supporting members 53a is the same length. Consequently, as depicted in FIG. 5(a), the first radiation surface 54 and the second radiation surface 55 are substantially parallel, and the radiation part 52a is maintained in a flat shape. However, with the radiation panel structure 5b according to the second embodiment, each of the plurality of shape supporting members 53b is not the same length, but rather has differing lengths so that a radiation part 52b has an arbitrary shape. Namely, as depicted in FIG. 5(b), the length of the shape supporting members 53b increases, in a side view, toward the center, and the length increases as a linear function advancing from the side end to the center. Consequently, when air is taken into the pressure generating space PS, the first radiation surface 54 bulges increasingly downward the closer the position to the center thereof. Further, two

inclined surfaces

540, 541 that sandwich the center are formed in the first radiation surface 54. These two inclined surfaces are connected at the center of the first radiation surface 54, and are respectively inclined downward toward the center of the first radiation surface 54. Furthermore, in FIG. 5, symbols are affixed to only one of the shape supporting members 53b and are omitted from the other shape supporting members 53b.

In addition, as depicted in FIG. 5(c), it is also acceptable if a curved surface, in a side view, is formed in the first radiation surface 54 that is smoothly curved downwardly convex. This curved surface is curved so that the center of the first radiation surface 54 bulges downward.

Other aspects of this constitution are the same as the air conditioner 1a according to the first embodiment.

<CHARACTERISTICS>

If the radiation part 52a is flatly formed as depicted in FIG. 5(a), then a difference in the radiation quantity arises depending on the position of the occupants and the like who are below the first radiation surface 54. Namely, the shape factor, which affects the radiation quantity, differs for the case in which the occupants and the like are at the center of the first radiation surface 54 and for the case in which the occupants and the like are at the edges of the first radiation surface 54. Consequently, a difference in the radiation quantity received by the occupants and the like differs for the case in which the occupants and the like are below the center of the first radiation surface 54 and for the case in which the occupants and the like are below the edges of the first radiation surface 54. Specifically, the radiation quantity is greatest at the vicinity of the center, and decreases toward the edges.

However, with the radiation panel structure 5b according to the present embodiment, the plurality of shape supporting members 53b maintains the radiation part 52b in the shape as described above, and it is possible to thereby change the direction of radiation (refer to the solid arrows A5, A6). Accordingly, the shape factor of the radiation part 52b can be made substantially equal with respect to an arbitrary location of the room. Thereby, the radiation quantity can be made substantially the same for the case in which an occupant is at the center of the first radiation surface 54 and for the case in which an occupant is at an edge of the first radiation surface 54. Accordingly, with this radiation panel structure 5b, the plurality of shape supporting members 53b enables a more uniform adjustment of the room temperature.

Furthermore, as depicted in FIG. 5(d), it is also acceptable to maintain the radiation part 52b in the shape of a type where the first radiation surface 54 is inclined. With this radiation panel structure, the shape supporting members, in a side view, lengthen the more they are positioned toward the left side, and the length of the shape supporting members increase as a linear function of advancing from the right side to the left side. Consequently, the first radiation surface 54 is inclined so that it slopes downward to the left side.

With this radiation panel structure, a substantially uniform radiation quantity is provided to the right side space of the indoor space below the radiation part 52b. Accordingly, if, for example, the space on the right side of the indoor space is the principle occupative area, then a more uniform temperature environment can be created than for occupants and the like at the peripheral space. Thereby, the comfort of the occupants and the like can be further increased.

In addition, the inclination angle and the curvature of the first radiation surface 54 can be more finely adjusted by changing the length and spacing of the abovementioned shape supporting members 53b. Accordingly, it is possible to make the first radiation surface 54 a shape so that it faces the direction where the temperature adjustment is needed. Consequently, it is possible to radiate and to blow out in a direction appropriate to the size of the room, the position of the occupants and the like, and so on. Thus, with this radiation panel structure 5b, the shape of the radiation part 52b can be maintained in an arbitrary shape so that a comfortable temperature environment is created.

Furthermore, it is also acceptable to determine the shape of the radiation part 52b from the viewpoint of design rather than the viewpoint of radiation quantity adjustment. Namely, by adjusting the length of the shape supporting members 53b, it is acceptable to reflect a designed shape in the radiation part 52b that visually stimulates the occupants and the like.

<THIRD EMBODIMENT> <CONSTITUTION>

With a radiation panel structure 5c according to the third embodiment of the present invention, the coarseness of the fiber weave of the first radiation surface 54 and the second radiation surface 55 varies by the portion. Specifically, a plurality of fine fiber weave portions and a plurality of coarse fiber weave portions are alternately disposed in the first radiation surface 54 (refer to FIG. 6). In addition, the coarseness of the fiber weave of the second radiation surface 55 varies by portion the same as in the first radiation surface 54.

Other aspects of the constitution are the same as for the air conditioner 1a according to the first embodiment.

<CHARACTERISTICS>

FIG. 6 depicts a side view of the radiation panel structure 5c in a state wherein air has been sent into a radiation part 52c.

With this radiation panel structure 5c, the coarseness of the fiber weave of the first radiation surface 54 and the second radiation surface 55 varies by portion, and the wind speed of the air blown out from the gaps of the fiber consequently varies by the portion (refer to the solid arrows A7, A8). Consequently, the reaction force due to the difference in the wind speed of the blown out air varies by portion. Further, this difference in the reaction force enables the direction in which first radiation surface 54 and the second radiation surface 55 sink to be changed by portion. In so doing, an irregular pattern is expressed in the surfaces of the first radiation surface 54 and the second radiation surface 55. Thereby, the occupants and the like are visually stimulated, enabling an improvement in the aesthetics of the radiation panel structure 5c.

<FOURTH EMBODIMENT> <CONSTITUTION>

With the radiation panel structure according to the fourth embodiment of the present invention, the radiation part 52a in the radiation panel structure 5a according to the first embodiment is capable of collecting undesirable substances, such as dust, viruses, and pollen, included in the air that passes through the gaps between the fibers of the woven fabric.

Other aspects of the constitution are the same as the air conditioner 1a according to the first embodiment.

<CHARACTERISTICS>

With this radiation panel structure 5a, when the air from the pressure generating space PS passes through the gaps between the fibers of the radiation part 52a and is blown out to the indoor space, the undesirable substances included in the air can be collected by the inner surfaces of the radiation part 52a, as depicted in FIG. 3. Namely, because the radiation part 52a is made of woven fabric, undesirable substances can be collected by the weave of the woven fabric. Consequently, with this radiation panel structure 5a, the undesirable substances can be eliminated from the air sent to the room, and the air in the room can thereby be cleanly maintained.

Furthermore, the present invention can also be applied to an air conditioner that takes in air from the outdoors and sends it to the radiation panel structure. With such an air conditioner, it is often the case that undesirable substances of the types mentioned above are included in the air. Consequently, the present invention, which is capable of collecting undesirable substances, is particularly effective.

<FIFTH EMBODIMENT> <CONSTITUTION>

With the radiation panel structure according to the fifth embodiment of the present invention, the radiation part 52a in the radiation panel structure 5a according to the first embodiment contains an active ingredient that eliminates unpleasant substances included in the air that passes between the fibers. Specifically, deodorizers, bactericides, and the like can eliminate odor causing chemical components and microorganisms from the air blown out from the pressure generating space PS into the room. It is acceptable to include such active ingredients in the woven fabric of the radiation part 52a, or to provide, separate from the woven fabric, a member that blows out active ingredients on the upstream side of the air blown out into the room.

<CHARACTERISTICS>

With this radiation panel structure 5a, the active ingredients possessed by the radiation part 52a can eliminate unpleasant substances included in the air that passes between the fibers of the woven fabric. Consequently, the air sent into the room can be deodorized and disinfected, and clean air can be blown out into the room. Thereby, the comfort of the occupants and the like in the room can be enhanced.

<SIXTH EMBODIMENT> <CONSTITUTION>

FIG. 7 depicts a radiation panel structure 5d according to the sixth embodiment of the present invention. This radiation panel structure 5d is detachably connected to an existing convection type air conditioner 100.

The convection type air conditioner 100 is a separate type air conditioner divided into an indoor unit 200 and an outdoor unit 300, and the indoor unit 200 is disposed on a side wall, in the vicinity of the ceiling surface, or the like, of the room. This convection type air conditioner 100 comprises refrigerant circuit components, such as an indoor heat exchanger 204, and an outdoor heat exchanger (not shown), the same as the air conditioner 1a according to the first embodiment, and constitutes a refrigerant circuit between the outdoor unit 300 and the indoor unit 200. The indoor unit 200 comprises an indoor unit casing 201, an indoor fan 203, and the like. The indoor unit casing 201 comprises an outlet 202 through which passes temperature adjusted air. The indoor fan 203 generates a current of air that is taken in from the room, passes through the indoor heat exchanger 204, and is blown out from the outlet 202. The convection type air conditioner 100 adjusts the temperature of the air taken into the indoor unit 200, and blows out temperature adjusted air from the outlet 202 provided in the indoor unit 200. Thus, this convection type air conditioner 100 can cool and heat a room on its own by blowing out temperature adjusted air from the outlet 202 into the room.

The radiation panel structure 5d is connected to the outlet 202 of the convection type air conditioner 100. Specifically, an air intake 51d of the radiation panel structure 5d is structured connectable to the outlet 202 of an existing convection type air conditioner 100. In addition, this air intake 51d and outlet 202 are detachable.

Other aspects of the constitution are the same as the radiation panel structure 5a according to the first embodiment.

<CHARACTERISTICS>

This radiation panel structure 5d can be connected to an existing convection type air conditioner 100. Accordingly, an air conditioner having the same performance as the air conditioner 1a according to the first embodiment can be easily constituted just by attaching the radiation panel structure 5d. Consequently, an existing convection type air conditioner 100 can be effectively utilized.

In addition, because the existing convection type air conditioner 100 and the radiation panel structure 5d are detachable, the radiation panel structure 5d can be easily attached and detached. Consequently, maintenance, such as cleaning and replacement, of the radiation panel structure 5d can be easily performed. For example, as in the radiation panel structure 5a according to the fourth embodiment, the present invention can be applied to a radiation panel structure capable of collecting undesirable substances, such as dust, viruses, and pollen, and maintenance, such as internal cleaning, of the radiation panel structure can thereby be easily performed.

<SEVENTH EMBODIMENT> <CONSTITUTION>

FIG. 8(a) depicts a side view of a radiation panel structure 5e according to the seventh embodiment of the present invention. The radiation panel structure 5e comprises a guide mechanism 57 (a modifying part). The guide mechanism 57 is provided in a radiation part 52e, and expands and contracts the radiation part 52e along the direction in which the air is blown in (refer to the outline arrow A9). This guide mechanism 57 expands and contracts the radiation part 52e into accordion-like folds, as depicted in FIG. 8(b). Thus, the guide mechanism 57 can increase or decrease the surface area of the first radiation surface 54 and the second radiation surface 55 by expanding and contracting the radiation part 52e.

<CHARACTERISTICS>

With this radiation panel structure 5e, the guide mechanism 57 can increase and decrease the surface area of the radiation part 52e. For example, as depicted in FIG. 8(b), the guide mechanism 57 can contract the portion of the radiation part 52e from the air intake 51 to the center, and can maintain the portion from the center to the tip in a flat shape. In this case, the surface area of the radiation part 52e is approximately half that of the state before contracting.

Thus, the radiation panel structure 5e can change the surface area of the first radiation surface 54 and the second radiation surface 55 by expanding and contracting the radiation part 52e. Furthermore, the radiation quantity and the quantity of temperature adjusted air blown out can be adjusted by changing the surface area of the first radiation surface 54 and the second radiation surface 55. In addition, the range over which heating and cooling is performed can also be adjusted.

Furthermore, the expansion and contraction of such a radiation part 52e may be performed manually or automatically. If expansion and contraction is performed automatically, then a drive mechanism (not shown) that drives the guide mechanism 57 is further provided. In addition, by controlling the drive mechanism with the control unit 6, the surface area of the radiation part 52e can also be automatically adjusted in accordance with the operating status, such as whether cooling or heating is being performed.

<EIGHTH EMBODIMENT> <CONSTITUTION>

FIG. 9 depicts an external view of one part of an air conditioner 1f according to the eighth embodiment of the present invention. With this air conditioner 1f, a radiation panel structure 5f comprises the guide mechanism 57 that expands and contracts a radiation part 52f, the same as the radiation panel structure 5f according to the seventh embodiment. In addition, an indoor unit casing 21f (the housing part) is provided with a housing opening 28 for housing the radiation panel structure 5f.

With this air conditioner 1f, when operation is stopped, the radiation panel structure 5f becomes smaller by the contraction of the radiation part 52f by the guide mechanism 57, as depicted in FIG. 10(a) and FIG. 10(b). Furthermore, as depicted in FIG. 10(c), the radiation panel structure 5f is housed inside the indoor unit casing 21f through the housing opening 28. Conversely, during operation of the air conditioner If, the housed radiation panel structure 5f is taken out and the radiation part 52f is expanded.

In addition, it is also acceptable for the radiation panel structure 5f to be expanded and contracted by the guide mechanism 57 rolling up the radiation part 52f into a cylindrical shape, as depicted in FIG. 11 (a). The radiation panel structure 5f becomes smaller by the guide mechanism 57 curling up the radiation part 52f into a cylindrical shape. Further, the radiation panel, which has become smaller, is housed inside the indoor unit casing 21f from the housing opening 28.

Furthermore, instead of expanding and contracting in an accordion shape or being curled up as described above, it is also acceptable for the radiation part 52f to be folded into strips.

<CHARACTERISTICS>

With this air conditioner 1f, the guide mechanism 57 can reduce the size of the radiation panel structure 5f, and can house it in the indoor unit casing 21f. Consequently, by housing the radiation panel structure 5f beforehand, the radiation panel structure 5f does not interfere with the occupants and the like when operation of the air conditioner 1f is stopped. In addition, during operation of the air conditioner 1f, taking the radiation panel structure 5f out of the indoor unit casing 21f and expanding it enables the room temperature to be adjusted once again.

Furthermore, the present invention is not limited to the case wherein the radiation panel structure 5f is housed in the indoor unit casing 21f, and the radiation panel structure 5f may also be provided with a housing part that houses the radiation part 52f. Effects the same as those described above can also be achieved in this case.

<NINTH EMBODIMENT> <CONSTITUTION>

With the air conditioner according to the ninth embodiment of the present invention, control is performed as depicted in FIG. 12 in the air conditioner 1a of the first embodiment. With this air conditioner 1a, if the control unit 6 receives an operation stop command when the air conditioner 1a is performing cooling operation, then the control unit 6 performs drying control prior to stopping the operation of the air conditioner 1a. Drying control suppresses the generation of condensation by the radiation part 52a. With this drying control, air of a temperature higher than the room temperature is sent to the radiation part 52a by the control unit 6 controlling the indoor fan 23 and the temperature of the air sent to the pressure generating space PS of the radiation part 52a. Thereby, the generation of condensation in the radiation part 52a can be suppressed.

First, in step S1, if the control unit 6 receives operation stop command of an air conditioner 1a from the remote control and the like, then processing proceeds to step S2.

In step S2, a timer is started, and the counting of time T is started. Then, processing proceeds to step S3.

In step S3, drying operation is performed at a temperature higher than the indoor temperature. Namely, with this drying operation, air of a temperature higher than the room temperature is sent to the radiation part 52a. Thereby, the radiation part 52a is heated and dried.

In step S4, the value of time T is decremented; in step S5, the process judges whether time T has reached zero, i.e., whether the count has ended. If the count has not ended, then processing returns to step S3, and drying operation continues. If the count has ended, then the operation of the air conditioner 1a is stopped in step S6.

Furthermore, the abovementioned time T is an empirically derived drying time.

<CHARACTERISTICS>

If the air conditioner 1a is performing cooling operation, then the surface temperature of the radiation part 52a falls due to the cold air blown out from the surface of the radiation part 52a. Furthermore, even immediately after the air conditioner 1a has stopped cooling operation, the surface of the radiation part 52a maintains a low temperature. Consequently, immediately after the air conditioner 1a stops cooling operation, the surface of the radiation part 52a makes contact with the indoor air having a high ambient humidity, which tends to generate condensation on the radiation part 52a.

With this air conditioner 1a, the control unit 6 performs a drying control that reduces the wetting of the radiation part 52a. In drying control, the control unit 6 blows out air, for a fixed time period, of a temperature higher than the room temperature prior to stopping the air conditioner 1a, as described above, and then stops the operation of the air conditioner 1a. Accordingly, the surface of the radiation part 52a is heated prior to stopping operation of the air conditioner 1a. Consequently, with this air conditioner 1a, the generation of condensation by the radiation part 52a can be prevented.

Furthermore, drying control is not limited to the case wherein drying operation is performed for just a predetermined time period as described above, and it is also acceptable to determine the time period for performing drying operation by detecting the temperature of the vicinity of the outer side of the radiation part 52a. FIG. 13 depicts a flow chart of drying control for this case.

First, in step S11, if the control unit 6 receives an air conditioner 1a operation stop command from the remote control and the like, then processing proceeds to step S12.

In step S12, drying operation is performed at a temperature slightly higher than the indoor temperature. Thereby, the radiation part 52a is heated.

In step S13, the process judges whether the temperature Th of the air in the vicinity of the outer side of the radiation part 52a is greater than or equal to, or slightly higher than the room temperature. Namely, in step S13, the process judges whether the temperature of the air in the vicinity of the outside of the radiation part 52a is higher than the room temperature by a prescribed temperature or greater. If the air temperature is low, then processing returns to step S12 and drying operation continues. If the air temperature is sufficiently high, then operation of the air conditioner 1a is stopped in step S14.

In addition, it is effective to perform drying control not only for the case wherein cooling operation is performed as described above, but also for cases where other operations are performed. For example, for the case of an air conditioner that takes in air from the outdoors and blows it out into the room, the abovementioned drying control can prevent the generation of condensation by the radiation part for the case where outdoor high humidity air is taken in and blown out, for the case where air from the outdoors is taken in during the winter, and the like.

Furthermore, it is acceptable to perform drying control not only immediately before stopping operation of the air conditioner 1a as described above, but also during operation of the air conditioner 1a.

In addition, drying control is not limited to the objective of heating the radiation part 52a as described above, but may also be performed with the objective of drying the moisture included in the woven fabric of the radiation part 52a.

<TENTH EMBODIMENT> <CONSTITUTION>

With the air conditioner according to the tenth embodiment of the present invention, the control unit 6 controls the indoor fan 23 so that air is sent to the radiation panel structure 5a with a 1/f fluctuation.

<CHARACTERISTICS>

FIG. 14 depicts one part of the radiation panel structure 5a for the case where such control is performed.

With this air conditioner, air with a fluctuation of 1/f is sent to the radiation part 52a. Because the radiation part 52a is made of woven fabric that is flexible, the first radiation surface 54 and the second radiation surface 55 fluctuate with a rhythm of 1/f due to air fluctuations. Accordingly, as depicted by the solid arrows and the broken arrows in the figure, the radiation direction and the distance of the radiation, and the blow out direction vary with a rhythm of 1/f. Thereby, comfort can be enhanced by impinging the occupants and the like with a natural feeling. In addition, the fluctuation of the first radiation surface 54 can also provide the occupants and the like with visually natural aesthetics. As described above, this air conditioner can enhance the comfort of the occupants and the like in the room.

In addition, instead of a fluctuation of 1/f, it is also acceptable to provide a fluctuation of the characteristic value possessed by the radiation part 52a, the first radiation surface 54, and the like. In this case, the blow out and the like is varied by the sufficient fluctuation of the radiation part 52a or the first radiation surface 54, and the occupants and the like are also provided with visual variety. Thereby, the comfort of the occupants and the like can be enhanced.

FIG. 15 and FIG. 16 depict an air conditioning system S1 according to the eleventh embodiment of the present invention. FIG. 15 is a side view of the air conditioning system S1, and a room R wherein the air conditioning system S1 is disposed; and FIG. 16 is a cross sectional view taken along the XVI-XVI line in FIG. 15. This air conditioning system S1 comprises a transport pathway SP1 and an air conditioner 1i.

In addition, a bed B is provided in the room R. This bed B is, for example, a bed, and is disposed in the room R, such as a bedroom. The air conditioner 1i adjusts the temperature of the room R wherein the bed B is disposed.

<TRANSPORT PATHWAY>

As depicted in FIG. 15, the transport pathway SP1 is a space adjacent to the room R and that communicates with the lower part of the room R. The transport pathway SP1 is adjacent to a side of the room R, and houses an indoor unit 2i. The room R and the transport pathway SP1 are partitioned by a partition W. The partition W is provided extending from a floor F of the room R to a ceiling surface CL, and air can enter and exit between the room R and the transport pathway SP1. The transport pathway SP1 can take in air from the lower part of the room R and transport it to the indoor unit 2i.

Furthermore, the transport pathway SP1 may be a space dedicated to the transport of air for air conditioning, and may also use a housing space, such as a closet provided in a side surface of the room R.

<AIR CONDITIONER>

The air conditioner 1i comprises a radiation panel structure 5i, the indoor unit 2i, and the outdoor unit 3 (refer to FIG. 22), and is capable of air conditioning, such as heating and cooling, the room R by radiation and by blowing out temperature adjusted air.

<RADIATION PANEL STRUCTURE>

As depicted in FIG. 15, the radiation panel structure 5i is disposed in the vicinity of the ceiling surface CL along the ceiling surface CL, and performs air conditioning, such as heating and cooling, by radiation using the temperature of the temperature adjusted air, and by blowing out temperature adjusted air. As depicted in FIG. 15 and FIG. 16, the overall radiation panel structure 5i has a thin, plate shaped outline, and is flatly shaped. One side surface of the radiation panel structure 5i is proximate to the partition W, and is connected to the indoor unit 2i inside the transport pathway SP1. The radiation panel structure 5i comprises a radiation part 52i and an external frame 4i.

<RADIATION PANEL>

The radiation part 52i is the portion that radiates, and that blows out air. FIG. 17 depicts an external view of the radiation part 52i. FIG. 17(a) is a plan view of the radiation part 52i, and FIG. 17(b) is a side view of the radiation part 52i. Furthermore, the plan view of the radiation part 52i of FIG. 17(a) is a view looking up from below at the radiation part 52i installed in the ceiling surface CL. The radiation part 52i has a thin, plate shaped outline, and is flatly shaped. The radiation part 52i is disposed proximate to the ceiling surface CL of the room R, and has a rectangular outline shape in a plan view. The radiation part 52i has a size that substantially planarly covers the bed B, and is disposed directly above the bed B. The radiation part 52i comprises a bag part 53i, an internal frame 57i (the frame part) (refer to FIG. 19 and FIG. 20), and a heat insulating material 58i.

<BAG PART>

The bag part 53i is disposed directly above the bed B in the vicinity of the ceiling surface CL and substantially parallel to the ceiling surface CL, and has a size that substantially planarly covers the bed B. The bag part 53i is bag shaped and made of a fiber material, such as woven fabric or non-woven fabric, and internally constitutes the pressure generating space PS, as depicted in FIG. 18. Furthermore, FIG. 18 depicts a side cross sectional view of the bag part 53i, but the internal frame 57i, and the like, are omitted. The sending of temperature adjusted air from the indoor unit 2i generates a pressure greater than the atmospheric pressure in the pressure generating space PS. In addition, the fiber material that forms the bag part 53i is flexible, capable of transmitting air, and has a radiation rate of approximately 0.9. Consequently, the air sent to the pressure generating space PS is gently blown out from the gaps in the weave of the bag part 53i. In addition, by adjusting the temperature of the bag part 53i by the air sent to the pressure generating space PS, radiation is generated from the bag part 53i. Thereby, the room R can be temperature adjusted by radiation and by the gentle blowing out of air. Furthermore, the fiber material is elastic.

The bag part 53i has a flat, thin plate shape, and comprises the second radiation surface 55, the first radiation surface 54, and the side surfaces 56.

The second radiation surface 55 of the bag part 53i is the upper surface of the bag part 53i, and is disposed along the ceiling surface CL of the room R substantially parallel to the ceiling surface CL. In addition, the second radiation surface 55 of the bag part 53i is disposed proximate to the ceiling surface CL.

The first radiation surface 54 of the bag part 53i is the lower surface of the bag part 53i, and is disposed at a position facing the room R and substantially parallel to the ceiling surface CL. The first radiation surface 54 of the bag part 53i has a rectangular projected shape with respect to the room R below, as depicted in FIG. 17(a) and has a size on the order that, for example, planarly covers the bed B disposed in the room R.

The side surfaces 56 of the bag part 53i are each long, thin, and rectangular shaped, as depicted in FIG. 17(b). Radiation and the blow out of air are also generated from the side surfaces 56 of the bag part 53i, the same as from the second radiation surface 55 and the first radiation surface 54, and the radiation and blow out of air from the side surfaces 56 of the bag part 53i are collected in a desired direction by the external frame 4i. The external frame 4i is explained later in detail.

In addition, as depicted in FIG. 17(a), one of the side surfaces 56 of the bag part 53i is provided with an internal frame insertion hole 560, which is an opening through which the internal frame 57i is inserted; and an open/close part 561 that opens and closes the internal frame insertion hole 560. The open/close part 561 comprises a fastener that opens and closes the internal frame insertion hole 560.

Furthermore, one of the side surfaces 56 of the bag part 53i is provided with an air intake 51. The air intake 51 is a portion wherein temperature adjusted air is taken in; the air intake 51 is connected to one end of a duct 9, whose other end is attached to an outlet 27i of the indoor unit 2i, and air sent from the indoor unit 2i to the pressure generating space PS passes therethrough.

<INTERNAL FRAME>

The internal frame 57i is a member that is disposed inside the bag part 53i and that supports the bag part 53i in a thin, plate shape of the type described above. FIG. 19 depicts an external view of the internal frame 57i. FIG. 19(a) is a plan view of the internal frame 57i, and is a view of the internal frame 57i from the ceiling surface CL side. The internal frame 57i comprises a plurality of linear members L1- L6 combined in a flat shape. The plurality of linear members L1- L6 is each made of, for example, a member having a prescribed rigidity, such as a metal like stainless steel, a resin, and the like. The internal frame 57i is formed as a separate body from the bag part 53i, and the bag part 53i is detachable from the internal frame 57i.

As depicted in FIG. 19(a), an upper surface 58 of the internal frame 57i has a substantially rectangular outline shape, and comprises the two first linear members L1 that constitute the two long sides of the rectangle, and the plurality of second linear members L2 provided across the two first linear members L1. Two of the plurality of second linear members L2 constitute the short sides of the rectangle, and the other second linear members L2 are disposed substantially equispaced and parallel to the short sides of the rectangle. The second linear members L2 are made slightly longer than the spacing of the first linear members L1, and protruding parts 570 are consequently formed on both sides of each of the second linear members L2 and protrude slightly from the first linear members L1, i.e., the long sides of the rectangle. The upper surface 58 of this internal frame 57i maintains the second radiation surface 55 of the bag part 53i in a shape of the type described above.

As depicted in FIG. 20, a lower surface 59 of the internal frame 57i comprises the third linear members L3 combined in a rectangular shape of a size the same as the outline shape of the upper surface 58 of the internal frame 57i, the fourth linear members L4 combined in a rectangular shape slightly smaller than the outline shape of the upper surface 58 of the internal frame 57i, and the fifth linear members L5 that join the third linear members L3 and the fourth linear members L4. The lower surface 59 of this internal frame 57i maintains the first radiation surface 54 of the bag part 53i in a shape of the type described above. Furthermore, FIG. 20 is a cross sectional view taken along the XX-XX line in FIG. 19(b).

In addition, as depicted in FIG. 19(b), side surfaces 60 of the internal frame 57i comprise the plurality of sixth linear members L6 that connects the upper surface 58 and the lower surface 59 of the internal frame 57i. The side surfaces 60 of this internal frame 57i maintain the side surfaces 56 of the bag part 53i in a shape of the type described above.

The internal frame 57i is inserted from the internal frame insertion hole 560 of the bag part 53i depicted in FIG. 17(a) to the interior of the bag part 53i. The dimensions of the bag part 53i and the internal frame 57i are designed so that a predetermined tension acts upon the bag part 53i by closing the fastener of the open/close part 561 in a state with the internal frame 57i disposed inside the bag part 53i.

<HEAT INSULATING MATERIAL>

As depicted in FIG. 17(b) and FIG. 18, the heat insulating material 58i is fixed to the upper surface positioned on the ceiling surface CL side of the radiation part 52i, i.e., to the second radiation surface 55 of the bag part 53i, and is provided on the ceiling surface CL side of the pressure generating space PS. A gap of approximately 6 mm is provided between the second radiation surface 55 of the bag part 53i and the ceiling surface CL, and the heat insulating material 58i is fixed to the second radiation surface 55 of the bag part 53i, and faces this gap. The heat insulating material 58i is sheet shaped and has a thickness of approximately 5 mm, and the gap between the heat insulating material 58i and the ceiling surface CL is extremely small. Accordingly, the heat insulating material 58i is proximate to the ceiling surface CL. The heat insulating material 58i covers substantially the entirety of the second radiation surface 55 of the bag part 53i.

<EXTERNAL FRAME>

As depicted in FIG. 16, the external frame 4i is a wood frame combined so that its outline is a rectangular shape with one short side missing, and surrounds the side surfaces of the radiation part 52i outside of the bag part 53i, i.e., the side surfaces 56 of the bag part 53i. Furthermore, the material that constitutes the external frame 4i is not limited to wood, and may be one having a prescribed rigidity capable of supporting the radiation part 52i. Excepting the side surface 56 wherein the air intake 51 of the bag part 53i is provided, i.e., excepting the side surface 56 facing the partition W, the external frame 4i surrounds all of the other side surfaces 56. Accordingly, the external frame 4i surrounds the entirety of the side surfaces 56 of the radiation part 52i facing the room R. As depicted in FIG. 15, the upper end of the external frame 4i is fixed to the ceiling surface CL without any gaps, and the lower end is of a height substantially the same as the first radiation surface 54 of the bag part 53i. The dimension of the external frame 4i in the height direction is approximately 60 mm, and the radiation panel structure 5i is extremely thin shaped. Accordingly, the radiation panel structure 5i reduces the feeling by the occupants and the like in the room R of being cramped. Furthermore, the shape of the first radiation surface 54 bulges convexly downward due to the self weight, internal pressure, and the like, of the bag part 53i, but the height of the external frame 4i is substantially the same as the position at which it connects with the first radiation surface 54, which forms the base of the bulge, and the side surfaces 56.

In addition, as depicted in FIG. 21, the external frame 4i comprises support parts 40i that support the internal frame 57i. Furthermore, FIG. 21 is a cross sectional view taken along the XXI-XXI line in FIG. 16. A support part 40i is provided on both of the two long sides of the external frame 4i. Each support part 40i comprises a slit 41 i provided on the inner side of the external frame 4i, and a metal rail 42i provided in the slit 41i. The slit 41i is provided, within the inner side of the external frame 4i, at a position close to the ceiling surface CL, and is provided parallel to the ceiling surface CL. The protruding parts 570 of the internal frame 57i latch from the sides of the external frame 4i through these support parts 40i to the support parts 40i, and the radiation part 52i is thereby supported by the external frame 4i.

<INDOOR UNIT>

The indoor unit 2i sends temperature adjusted air to the pressure generating space PS of the radiation part 52i. As discussed above, the indoor unit 2i is disposed in the transport pathway SP1 partitioned from the room R, is the upper part of the transport pathway SP1, and is disposed in the vicinity of the radiation panel structure 5i of the room R. As depicted in FIG. 22, the indoor unit 2i comprises the indoor heat exchanger 22, the indoor fan 23, the indoor fan motor 24, and an indoor unit casing 21i (refer to FIG. 15).

The indoor unit casing 21i internally houses the indoor heat exchanger 22, the indoor fan 23, the indoor fan motor 24, and the like, and comprises an inlet 26i and the outlet 27i, as depicted in FIG. 18.

The inlet 26i is an opening through which passes the air taken in from the room R into the indoor unit casing 21 i. The inlet 26i is provided in the lower surface of the indoor unit casing 21i, and is provided facing downward so that air from below is sucked in. The inlet 26i is disposed lower than the radiation part 52i, and is disposed lower than the outlet 27i. The indoor unit 2i is disposed in the transport pathway SP1, and the inlet 26i is provided so that air from the lower part of the room R is sucked in via the transport pathway SP1. If a housing space, such as a closet, is used as the transport pathway SP1, then the air in the room is sucked in from gaps in the housing space, and is sucked in from the inlet 26i of the indoor unit 2i into the indoor unit 2i.

The outlet 27i is provided higher than the inlet 26i, and is an opening through which passes the air sent through the indoor heat exchanger 22 inside the indoor unit casing 21i to the radiation panel structure 5i. The outlet 27i is connected to one end of the duct 9, which is connected to the air intake 51 of the radiation panel structure 5i, and blows out the air of the indoor unit 2i in a substantially horizontal direction.

As shown in FIG. 22, the indoor heat exchanger 22 is connected via

refrigerant pipings

29a, 29b to an outdoor heat exchanger 30, the compressor 32, and the like. The indoor heat exchanger 22 adjusts the temperature of the air by exchanging heat with the air passing therethrough. The indoor fan motor 24 rotatably drives the indoor fan 23, which generates a current of air that is taken in from the room R and sent to the radiation panel structure 5i. This air current is taken in from the inlet 26i into the interior of the indoor unit casing 21i, passes through the indoor heat exchanger 22, the outlet 27i and the air intake 51, and arrives at the pressure generating space PS inside the radiation part 52i.

<OUTDOOR UNIT>

The outdoor unit 3 is disposed outdoors, and, as shown in FIG. 22, comprises the accumulator 31, the compressor 32, the four-way switching valve 32, the motor operated valve 33, an outdoor fan 38, an outdoor fan motor 39, the outdoor heat exchanger 30, and the like. The compressor 32, the motor operated valve 33, the four-way switching valve 32 , the outdoor heat exchanger 30, and the like, comprise the indoor heat exchanger 22 together with the refrigerant circuit. The outdoor fan motor 39 rotatably drives the outdoor fan 38, which generates a current of air that passes through the outdoor heat exchanger 30.

<OPERATION OF THE AIR CONDITIONER>

The following explains operation for the case wherein this air conditioning system S1 air conditions the room R.

During cooling operation, the indoor heat exchanger 22 functions as an evaporator, and captures the heat from the air passing therethrough. As shown in FIG. 23, the heat of the room R air taken in by the indoor fan 23 from the inlet 26i via the transport pathway SP1 into the indoor unit casing 21 i (refer to the solid arrow A5) is captured when it passes through the indoor heat exchanger 22, and is thereby cooled.

This cooled air is blown out from the outlet 27i, and sent through the duct 9 to the air intake 51 (refer to the solid arrow A6). This air blown out from the indoor unit 2i is sent to the pressure generating space PS inside the bag part 53i. When the air is sent to the pressure generating space PS, a positive static pressure greater than the atmospheric pressure is generated in the pressure generating space PS. Namely, a pressure greater than the atmospheric pressure is generated in a direction perpendicular to the flow of air flowing parallel to the ceiling surface CL (refer to the solid arrow A2). Consequently, the cooled air is pushed out from the gaps between the fibers of the bag part 53i, and gently blown out into the room R (refer to the solid arrow A3).

In addition, the bag part 53i is cooled when it makes contacts with the cooled air. Consequently, cold radiation is generated by the bag part 53i (refer to the broken arrow A4).

The gentle blow out of air and the cool air from radiation reach the bed B positioned directly below the bag part 53i, thereby cooling the surroundings of the bed B.

In addition, the air of the room R is sucked in from the lower part of the room R into the transport pathway SP1, and is sucked in once again from the inlet 26i of the indoor unit 2i into the indoor unit 2i.

Thus, when air is gently blown out from the gaps between the fibers of the bag part 53i with this air conditioning system S1, the room R is cooled by the cold radiation of the bag part 53i.

During heating operation, the indoor heat exchanger 22 functions as a condenser, and heats the air passing therethrough. The heated air is sent to the pressure generating space PS inside the bag part 53i, the same as during cooling operation. Further, the heated air is pushed out from the gaps between the fibers of the bag part 53i, and is gently blown out into the room R. In addition, the bag part 53i is heated when it makes contact with the heated air. Further, heat radiation is generated by the bag part 53i.

This gentle blowing out of air and heated air from radiation reaches the bed B positioned directly below the bag part 53i, and heats the surroundings of the bed B. Thus, with this air conditioning system S1, the room R is heated by the gentle blow out of air from the gaps between the fibers of the bag part 53i, and by the heat radiation of the bag part 53i.

<CHARACTERISTICS> <1>

With this air conditioning system S1, the air sent from the indoor unit 2i to the radiation part 52i in the vicinity of the ceiling surface CL is blown out into the room R, circulates in the room R, returns to the indoor unit 2i, and is once again blown out from the radiation part 52i, as described above. Consequently, with this air conditioning system S1, it is possible to ensure the circulation of air circulating in the room R.

<2>

With this air conditioning system S1, the outlet 27i of the indoor unit 2i is provided higher than the inlet 26i. The outlet 27i is connected to the radiation part 52i provided in the vicinity of the ceiling surface CL; however, with this indoor unit 2i, the outlet 27i is provided above, making it easy to connect the indoor unit 2i to the radiation part 52i provided in the vicinity of the ceiling surface CL.

In particular, even if the space above the indoor unit 2i is limited, the connection between the indoor unit 2i and the radiation part 52i is easy, as is the installation of the indoor unit 2i. In addition, because the inlet 26i is provided below the outlet 27i, the indoor unit 2i can adequately suck in air from the space below, which has ample space compared with the space above.

<TWELFTH EMBODIMENT> <CONSTITUTION>

With the abovementioned first embodiment, the indoor unit 2i is disposed in the transport pathway SP1 provided on a side of the room R, but an indoor unit 2j may be disposed in the floor F of the room R, as in an air conditioning system S2 depicted in FIG. 24. With the indoor unit 2j, an inlet 26j is provided on the side of an indoor unit casing 21j, and sucks in air from the vicinity of the floor F of the room. The air sucked into the indoor unit 2j is blown out from an outlet 27j, and sent to the radiation part 52i through a duct 91 that connects the outlet 27j with the air intake 51 of the radiation part 52i.

Other aspects of the constitution are the same as the air conditioning system S1 according to the eleventh embodiment.

<CHARACTERISTICS>

According to this air conditioning system S2, the indoor unit 2j can suck in from the vicinity of the floor F the air that was blown out from the vicinity of the ceiling surface CL, and once again blow that air out from the vicinity of the ceiling surface CL. Consequently, according to this air conditioning system S2, circulation can be more favorably ensured, and the temperature can be more effectively adjusted.

<THIRTEENTH EMBODIMENT> <CONSTITUTION>

With the abovementioned eleventh embodiment, the indoor unit 2i is disposed at the upper part of the transport pathway SP1 provided on a side of the room R; however, as with an air conditioning system S3 depicted in FIG. 25, an indoor unit 2k may be housed in an indoor unit housing SP2 provided in the vicinity of the ceiling surface CL of the room R. This indoor unit housing SP2 projects from the ceiling surface CL into the room R so that it covers the indoor unit 2k, and is provided adjacent to the upper part of a side wall of the room R. The indoor unit 2k is constituted the same as the indoor unit 2i according to the first embodiment, and comprises an inlet 26k and an outlet 27k.

<CHARACTERISTICS>

With such an air conditioning system S3 as well, the installation of the indoor unit 2k is easy, the same as in the first embodiment. In particular, because the indoor unit housing SP2 can be formed relatively small, the work of installation in the room is simple, and more of the space in the room R can be utilized as living space. In addition, there is little risk of adversely affecting the interior aesthetics of the overall room R.

In addition, by sucking in air from the lower part of the indoor unit housing SP2 into the indoor unit housing SP2, a more favorable circulation of air can be ensured in the room R.

<FOURTEENTH EMBODIMENT> <CONSTITUTION>

With the abovementioned eleventh embodiment, the indoor unit 2i is disposed in the transport pathway SP1 provided on a side of the room R, but an indoor unit 2m may be provided outdoors, as in an air conditioning system S4 depicted in FIG. 26. The indoor unit 2m sucks in air from the outdoors and sends it to the radiation part 52i. The indoor unit 2m is constituted the same as the indoor unit 2i according to the first embodiment, and comprises an inlet 26m and an outlet 27m.

Other aspects of the constitution are the same as the air conditioning system S4 according to the eleventh embodiment.

<CHARACTERISTICS>

With such an air conditioning system S4 as well, the installation of the indoor unit 2m is easy, the same as the air conditioning system S1 according to the eleventh embodiment. Namely, because the outlet 27m is provided above, it is easy to connect the outlet 27m with a duct 92, which extends from the radiation part 52i. Consequently, the installation of the indoor unit 2m is easy.

In addition, an inlet may be provided on a wall surface of the room R, and connected to the inlet 26m of the indoor unit 2m via a duct, and the like. Thereby, the temperature adjusted air is blown out from the vicinity of the ceiling surface CL of the room R, sucked in from the inlet of the side wall, and sent once again to the room R. Thereby, favorable circulation can be ensured.

<FIFTEENTH EMBODIMENT> <CONSTITUTION>

With the eleventh embodiment, the indoor unit 2i is disposed in the transport pathway SP1 provided on a side of the room R, but an indoor unit 2n may be housed behind the ceiling as in the air conditioning system S5 depicted in FIG. 27. The indoor unit 2n sucks in the air of the room R from an inlet 26n provided on the lower surface, and blows out temperature adjusted air from an outlet 27n in a substantially horizontal direction. The air blown out from the outlet 27n is sent to the radiation part 52i through a duct 93.

<CHARACTERISTICS>

In such an air conditioning system S5 as well, the effect of ensuring the circulation of air in the room R is obtained, the same as the air conditioning system S1 according to the eleventh embodiment.

In addition, because the indoor unit 2n is provided behind the ceiling, the indoor unit 2n can be hidden from the visual field of the occupants and the like in the room R. Thereby, the aesthetics of the room R can be enhanced.

<OTHER EMBODIMENTS> <1>

In the abovementioned embodiments, the radiation panel structure 5a is disposed in the vicinity of the ceiling surface, but the radiation panel structure may be disposed along the vicinity of a side wall of the room.

Furthermore, as depicted in FIG. 28(c), the radiation part 52g may comprise a fifth flat surface 525g parallel to a side wall, and a sixth flat surface 526g that extends perpendicularly from the side end of the fifth flat surface 525g and that is parallel to another side wall.

As described above, by making the radiation part 52g shaped bent midway, a temperature environment can be created that conforms to the desires of the occupants and the like. In addition, with a radiation panel structure 5g according to the present invention, the radiation part 52g is made of woven fabric, and it is consequently easy to shape the radiation part 52g bent midway.

<2>

With the abovementioned embodiments, the radiation part 52a is a closed bag shape, excepting the air intake 51; however, as shown in FIG. 29, it may be shaped with the air intake 51 and the ceiling surface side open. This radiation part 52h comprises a first radiation surface 54 disposed in the vicinity of the ceiling surface opposing the living space of the room, and three side surfaces 56 that join the first radiation surface 54 and the ceiling surface. The first radiation surface 54 closes the lower part of the pressure generating space PS, and the three side surfaces 56 close the sides of the pressure generating space PS, excepting the air intake port.

Furthermore, FIG. 29(a) is a side view of a radiation panel structure 5h seen from a direction perpendicular to the air current of the pressure generating space PS (solid arrow A2), and FIG. 29(b) is a side view of the radiation panel structure 5h seen from the direction of the air current of the pressure generating space PS.

In such a radiation panel structure 5h as well, the effect the same as mentioned above can be achieved by constituting the pressure generating space PS between the ceiling surface and the first radiation surface 54.

In addition, the radiation panel structure 5h may comprise two side surfaces 56 instead of three. For example, in the abovementioned radiation panel structure 5h, it is acceptable if the side surface 56 perpendicular to the direction of the air flowing through the pressure generating space PS, i.e., the side surface 56 positioned at the tip of the radiation part 52h, does not exist. In this case as well, the effect the same as mentioned above can be achieved by the generation of internal static pressure in a direction perpendicular to the air flowing through the pressure generating space PS. In addition, because the side opposite the air intake 51 of the radiation part 52h is open, air from this portion can be blown out into the room. Consequently, the temperature adjusted air can be sent distantly. Accordingly, temperature adjusted air can be made to sufficiently reach the indoor space, thereby enabling the creation of a more comfortable temperature environment.

<3>

With the abovementioned embodiments, the first radiation surface 54 and the second radiation surface 55 are flatly formed; however, if shaped in this manner, then the radiation panel structure 5a disposed in the vicinity of the ceiling surface may block the illumination, and the like. Accordingly, the radiation part 52a may be shaped so that it avoids the portion opposing the illumination, and the like. For example, the portion opposing the illumination, and the like, may be provided with an opening, a notch, or the like. In addition, if the radiation panel structure 5a is provided in the vicinity of a side wall, then it may be shaped to avoid the window, and the like. Thereby, the radiation panel structure 5a can prevent becoming an obstruction to the illumination, and the like.

Furthermore, because the radiation part 52a of the radiation panel structure 5a is made of woven fabric, it is easy to form it into a shape, unlike metal and the like. Consequently, it can be formed easily even if it is a complex shape of the type mentioned above.

<4>

With the abovementioned embodiments, the air in the room is taken into the indoor unit casing 21a, and sent to the radiation panel structure 5a; however, it is also acceptable to send to the radiation panel structure 5a air that was taken in from the outdoors.

<5>

With the abovementioned embodiments, woven fabric was used as the material of the radiation part 52a, but a fiber material other than woven fabric may also be used.

<6>

With the abovementioned embodiments, the entire radiation part 52a was made of woven fabric; however, it is also acceptable if only the first radiation surface 54 is made of woven fabric and the other portions are made of another material that is flexible.

In addition, from the viewpoint of preventing drafts, it is also acceptable if only the first radiation surface 54 is made of woven fabric, and the other portions are made of another material that is rigid. In this case as well, drafts can be prevented by the radiation and the gentle blow out from the first radiation surface 54.

<7>

The abovementioned embodiments principally recited heating operation and cooling operation; however, humidifying operation and dehumidifying operation may also be performed by sending humidity adjusted air to the radiation part 52a and the like. In addition, heating operation and cooling operation may also be performed simultaneous with humidifying operation and dehumidifying operation. Furthermore, ventilating operation may also be performed by sending to the radiation part 52a air from the outdoors that has not been temperature adjusted, and the like.

<8>

With the abovementioned embodiments, the radiation panel structure 5a is connected to the connection port 27a of the indoor unit casing 21 a; however, if a duct exit that blows out air is provided directly in a room side wall, ceiling surface, or the like, then the radiation panel structure 5a may be connected to the duct exit.

<9>

In the abovementioned embodiments, the first radiation surface 54, the second radiation surface 55, and the side surfaces 56 may be of a single body, instead of separately formed and joined bodies.

<10>

In the abovementioned embodiments, the air conditioner 1a is not limited to a separate type wherein the outdoor unit 3 and the indoor unit 2a of the type mentioned above are separate bodies, but may be an integrated type air conditioner.

<11>

With the abovementioned embodiments, woven fabric having a radiation rate of 0.9 is used; however, it may be woven fabric having a radiation rate of 0.6 or greater, more preferably 0.7 or greater, or 0.8 or greater. Furthermore, the woven fabric may have a radiation rate of 0.6 or less, in accordance with the required radiation performance, the application, and the like; in this case as well, it is possible to adjust the temperature of the room.

<12>

With the abovementioned embodiments, the bag part 53i was made of a fiber material, but another material having a prescribed radiation rate and capable of transmitting air may be used. For example, a porous resin film, and the like, may be used.

<13>

With the abovementioned embodiments, the material that forms the bag part 53i is not necessarily of one type, and the bag part 53i may be made of material having a plurality of differing elasticities. For example, it is conceivable to form the center part of the lower surface of the bag part 53i with a material having comparatively low elasticity, and to form the peripheral portion of the lower surface of the bag part 53i with a material having a comparatively high elasticity. In this case, when air is sent to the pressure generating space PS, the degree of bulging by the bag part 53i due to the static pressure differs by the portion. Accordingly, by forming the bag part 53i with a material having a plurality of differing elasticities, the bag part 53i in a bulging state can be made into a desired shape.

<14>

In the abovementioned air conditioning system S1, a curtain is further provided that extends downward and envelops the periphery of the radiation part 52i, the periphery of the external frame 4i, and the like. This curtain concentrates the air blow out and the radiation to a specific space below, and mitigates the impact on other spaces, e.g., a curtain made of a fiber material and the like, an air curtain, and the like.

The provision of such a curtain enables the more effective temperature adjustment of the specific space. For example, by providing a curtain so that it extends from the radiation part 52i to the bed B and envelops the periphery of the bed B, the periphery of the bed B can be intensively temperature adjusted, making more effective temperature adjustment possible.

<15>

In the abovementioned embodiments, the radiation part 52i may be of a size substantially the same as the bed B, slightly smaller than the bed B, larger than the bed B and covering a large area of the ceiling surface CL, and the like.

<16>

It is also acceptable to provide the external frame 4i and the like with a radiation temperature sensor, to provide the indoor unit with an inlet temperature sensor, and for a control unit (not shown) to perform temperature control of the room. The radiation temperature sensor measures the radiation temperature of the target person, the bed, and the like. The temperature of the room R is measured by measuring the temperature of the air sucked into the indoor unit. The control unit controls the temperature, flow volume, and the like, of the air blown out based on the radiation temperature and the inlet temperature. Thereby, it is possible to more appropriately control the temperature of the room R.

In addition, it is also acceptable to make the structure capable of changing the orientation of the abovementioned radiation temperature sensor. It thereby becomes possible to measure the radiation temperature of the portion of the radiation part 52i that requires measurement of the radiation temperature, and it is therefore possible to more appropriately control the temperature of the room R.

Furthermore, the radiation temperature sensor may serve double duty as a human sensor. By the radiation temperature sensor sensing the entrance and exit of people to and from the room R, it is possible to perform control that automatically turns the air conditioner 1i on and off in accordance with the entrance and exit of people.

<17>

With the air conditioning system S1 according to the abovementioned first embodiment, the heat insulating material 58i was fixed to the bag part 53i, but the heat insulating material 58i may be fixed to the internal frame 57i. In addition, the heat insulating material 58i may be fixed to the external frame 4i. With such a constitution as well, it is also possible to suppress the generation of condensation at the ceiling surface CL, the same as mentioned above.

<18>

With the air conditioning system S1 according to the abovementioned first embodiment, the air of room R is taken into the indoor unit casing 21i and sent to the radiation panel structure 5i, but air taken in from the outdoors may be sent to the radiation panel structure 5i. In addition, a ventilating apparatus that integrates the indoor unit 2i and the outdoor unit 3 may be used.

<19>

With the air conditioning system S1 according to the abovementioned first embodiment, the radiation part 52i is rectangularly shaped in a plan view, but may be of another shape. For example, it may be another polygonal shape, such as a square or hexagon, or it may be a circle, and the like.

<20>

With the abovementioned embodiments, the radiation part 52i and the indoor unit 2i are connected via the duct 9, but the radiation part 52i may be fixed to the indoor unit 2i, or the radiation part 52i and the indoor unit 2i may be integrated.

<21>

With the abovementioned embodiments, the radiation panel structure 5i is provided along the surface of the flat ceiling surface CL; however, as shown in FIG. 30, a hollow portion CLS wherein the radiation panel structure 5i is housed may be provided in the ceiling surface CL, and the radiation panel structure 5i may be installed in this hollow portion CLS.

According to such a constitution, it is possible to suppress the protrusion of the radiation panel structure 5i into the room R, and to improve the aesthetics of the room R.

In addition, by making the bag part 53i of the radiation panel structure 5i detachable from the internal frame 57i, the bag part 53i can be easily detached, even if the radiation panel structure 5i is provided and embedded in the ceiling surface CL in this manner, thereby improving serviceability.

Furthermore, by making the first radiation surface 54 of the bag part 53i (the sheet part) detachable from other portions of the bag part 53i and from the internal frame, instead of only making the entire bag part 53i detachable, it is possible to detach only the first radiation surface 54 from other portions during maintenance, without detaching the entire bag part 53i. Serviceability is thereby further improved.

<22>

With the abovementioned embodiments, the pressure generating space PS is constituted by a bag shaped bag part 53i; however, the pressure generating space component that constitutes the pressure generating space PS does not necessarily have to be bag shaped. For example, as shown in FIG. 31, the pressure generating space PS may be constituted by the combination of a sheet shaped sheet part 54j and other members. The sheet part 54j is made of a porous material, such as a fiber material, the same as the abovementioned bag part 53i. Furthermore, along with the sheet part 54j, the internal frame 57i, the external frame 4i, the ceiling surface CL, and the like, of the abovementioned embodiments are conceivable as the other members that constitute the pressure generating space PS. Such a constitution enables the same effect as mentioned above to be achieved.

<23>

In the abovementioned embodiments, it is preferable, from the perspective of reducing the feeling by the occupants in the room R of being cramped, that the thickness of the

radiation parts

52a, 52i be 80 mm or less. In addition, it is more preferable that it be 60 mm or less. The smaller the lower limit of the thickness, the better; for example, 10 mm or greater, 1 mm or greater, and the like, are conceivable.

In addition, from the viewpoint of enhancing the effects of radiation and blow out, it is preferable that the

radiation parts

52a, 52i have a flat surface of 2 m² or greater. Specifically, it is preferable that the first radiation surface 54 have a surface area of 2 m² or greater. Furthermore, if the first radiation surface 54 is rectangular, then it is more preferable that one side be 1,000 mm or greater, or 1,500 mm or greater, and that the other side be 2,000 mm or greater, or 2,500 mm or greater.

Furthermore, it is more preferable that the

radiation parts

52a, 52i have a thickness of 1/5 or less of the short lateral width. Namely, it is preferable that the length of the side surface in the height direction is 1/5 or less the lateral width of the short side of the first radiation surface 54.

<24>

As depicted in FIG. 32, a radiation panel structure 5p is disposed opposing a light source, such as an illumination LT provided in the ceiling surface CL, and a second radiation surface 55p (transmitting part) may be made of a transparent material. The second radiation surface 55p is disposed between a first radiation surface 54p and the ceiling surface CL, is positioned between the illumination LT and a first radiation surface 54p, and sufficiently transmits the light of the illumination LT to the first radiation surface 54p side. The first radiation surface 54p has the same constitution as the first radiation surface 54 according to the first embodiment, and the disposition, shape, and the like, of the second radiation surface 55p are the same as the second radiation surface 55 according to the first embodiment. In addition, other aspects of the constitution of the radiation panel structure 5p are the same as the radiation panel structure 5a according to the first embodiment.

This radiation panel structure 5p not only performs temperature adjustment of the room, but can also achieve the effect of indirect illumination using the illumination LT of the room. Namely, the radiation panel structure 5p is disposed in the vicinity of the ceiling surface CL of the room, and opposes the illumination LT. Further, the second radiation surface 55p opposing the ceiling surface CL is transparent. Consequently, the light emitted from the illumination LT is transmitted through the second radiation surface 55p, and reaches the upper side of the first radiation surface 54p (the ceiling side). Because the first radiation surface 54p is made of woven fabric, the light that reaches the upper side of the first radiation surface 54p is transmitted to below the first radiation surface 54p through the gaps in the woven fabric. Consequently, the first radiation surface 54p diffuses the light of the illumination LT, and thereby functions as indirect illumination. Consequently, the room is illuminated by a light that is softer than the direct light of the illumination LT.

Thus, with this radiation panel structure 5p, the radiation panel structure 5p of the type mentioned above functions as indirect illumination using the illumination LT. Consequently, a soft illumination effect is obtained. Thereby, with this radiation panel structure 5p, the occupants and the like are favorably affected visually, and the comfort of the occupants and the like can be enhanced. In addition, because the radiation panel structure 5p is integrated with the illumination LT and functions as the interior, the occupants and the like can be provided with more than just air conditioning, i.e., they can also be provided with the effect of comfort. Furthermore, the effect of indirect illumination of the type described above can also be obtained if the second radiation surface 55p has light transmissivity to some extent, even if it is not transparent.

Furthermore, as in a radiation panel structure 5q depicted in FIG. 33, a first radiation surface 54q may comprise a first transmitting part 57q having a first light transmittance, and a second transmitting part 58q having a second light transmittance. The light transmittance is on an order that transmits light. The first transmitting part 57q and the second transmitting part 58q are both made of woven fabric, but the coarseness of the weave of the woven fabric differs for the first transmitting part 57q and the second transmitting part 58q. The weave of the first transmitting part 57q is rough, and is looser than that of the second transmitting part 58q. Consequently, the first light transmittance of the first transmitting part 57q is greater than the second light transmittance of the second transmitting part 58q, and the first transmitting part 57q therefore transmits light more than the second transmitting part 58q. Other aspects of the constitution are the same as the abovementioned radiation panel structure 5p.

With this radiation panel structure 5q, it is possible to transmit light at transmittances that differ between the first transmitting part 57q and the second transmitting part 58q. Consequently, an illumination effect is obtained that differs by the portion of the room R. Accordingly, it is possible to provide the room with illumination suited to the occupants and the like by disposing the first transmitting part 57q and the second transmitting part 58q in accordance with the room R usage circumstances, and the like. Thereby, the comfort of the occupants and the like can be enhanced.

Furthermore, as in a radiation panel structure 5r depicted in FIG. 34, a first radiation surface 54r constitutes the ceiling surface CL together with the pressure generating space PS, the light source LT is provided inside a radiation part 52r, and a first radiation surface 54r may be disposed opposing the illumination LT. Thereby, the effect of indirect illumination can also be obtained the same as mentioned above. In addition, a first transmitting part 57r, which is one part of the first radiation surface 54r, may be transparent and positioned directly below the illumination LT. The first transmitting part 57r has a shape slightly larger than the projected area of the illumination LT. Furthermore, the first transmitting part 57r is provided with a plurality of minute holes. In addition, the first transmitting part 57r is attached to a second transmitting part 58r by a fastener, and the like, and is freely detachable. Furthermore, one part of the second transmitting part 58r positioned directly below the illumination LT is also attached to another portion by a fastener, and the like, and is freely detachable. The portion excluding the first transmitting part 57r of the first radiation surface 54r forms the second transmitting part 58r, which is made of woven fabric. In addition, a transparent part 55r, which is transparent, is provided between the first radiation surface 54r and the illumination LT. Other aspects of the constitution are the same as the abovementioned radiation panel structure 5p.

With this radiation panel structure 5r, the transparent first transmitting part 57r is positioned directly below the illumination LT. Consequently, the light of the illumination LT passes through the transparent part 55r and the first transmitting part 57r, and irradiates the living space of the room R (refer to the broken arrow A10) almost without weakening. Consequently, obstruction of the illumination by the radiation panel structure 5r is prevented. Accordingly, it is effective especially in the case where direct light stronger than indirect illumination is needed. Thereby, the comfort of the occupants and the like is enhanced.

<25>

As in a radiation panel structure 5s depicted in FIG. 35, it may be constituted so that a first radiation surface 54s comprises a first colored part 57s and a second colored part 58s. The first colored part 57s has a first color, and the second colored part 58s has a second color. The first color and the second color are different colors, and the first color has a higher radiation rate than the second color. The first colored part 57s is distributed along the edge part of the first radiation surface 54s, and the surface area of the portion positioned at the vicinity of the tip of a radiation part 52s is comparatively large. The second colored part 58s is distributed from a position proximate to the air intake 51 of the first radiation surface 54s toward the vicinity of the center of the first radiation surface 54s. Other aspects of the constitution are the same as the radiation panel structure 5a according to the first embodiment.

With this radiation panel structure 5s, the first colored part 57s is distributed along the edge part of the first radiation surface 54s. Consequently, the first colored part 57s is positioned above the vicinity of a side wall of the room R in a state wherein the radiation panel structure 5s is disposed in the vicinity of the ceiling surface CL. Furthermore, the radiation rate of the first colored part 57s is higher than the radiation rate of the second colored part 58s. Accordingly, heating and cooling of the vicinity of the side walls of the room R are performed slightly more strongly due to the radiation from the first colored part 57s. In addition, the second colored part 58s is distributed from a position proximate to the air intake 51 of the first radiation surface 54s toward the vicinity of the center of the first radiation surface 54s. Consequently, the second colored part 58s is positioned above the vicinity of the center portion of the room R. Accordingly, cooling and heating of the vicinity of the center of the room R by the radiation from the second colored part 58s is performed slightly more strongly.

Thus, with this radiation panel structure 5s, the vicinity of the side walls of the room R are strongly cooled and heated, and the center portion of the room R is weakly cooled and heated. Thereby, it is possible to prevent excessive cooling and heating of the occupants and the like under room R usage conditions such as when there are many occupants and the like in the vicinity of the center of the room R. In addition, because the side walls are strongly cooled and heated, the temperature of the room R is efficiently adjusted.

In addition, by making both the first color and the second color cool colors, it is possible to achieve a visual effect that gives a cool impression. Conversely, by making both the first color and the second color warm colors, it is possible to achieve a visual affect that gives a warm impression.

Furthermore, a design may be reflected in the first radiation surface 54s by the use of the first color and the second color, or by the use of more numerous colors. This improves the interior design of the radiation panel structure 5s.

<26>

An air conditioner may be constituted so that it is possible to switch between air conditioning by radiation from a first radiation surface 54t and the gentle blow out of air, and air conditioning by direct blow out into the room R. A radiation panel structure 5t depicted in FIG. 36 comprises a switching apparatus 8t. The switching apparatus 8t comprises a switching apparatus casing 61t, a switching damper 63t (a switching means), and the like, and is provided between an indoor unit 2t and a radiation part 52t. The switching apparatus casing 61t is provided with a connection mechanism (not shown), an inlet 64t, a first outlet 65t, a second outlet 66t, and the like. The connection mechanism is a portion detachably fixed to the periphery of a ventilation port 27t of the indoor unit 2t, and the switching apparatus 8t is fixed to the indoor unit 2t by the connection mechanism. The inlet 64t is detachably connected to the ventilation port 27t of the indoor unit 2t by the connection mechanism, and sucks in the air blown out from the ventilation port 27t. The first outlet 65t is connected to the air intake 51 of the radiation part 52t, and blows out the air sucked in from the inlet 64t to the pressure generating space PS of the radiation part 52t. The second outlet 66t is provided in the lower surface of the switching apparatus casing 61t, downwardly blows out the air sucked in from the inlet 64t, and blows out the air sent from the indoor unit 2t into the room R (refer to FIG. 37). The switching damper 63t switches between blow out from the first outlet 65t and blow out from the second outlet 66t. Other aspects of the constitution are the same as the air conditioner 1a according to the first embodiment.

According to such an air conditioner 1t, by switching between blow out of air from the first outlet 65t and blow out of air from the second outlet 66t, it is possible to switch between air conditioning by radiation from the first radiation surface 54t and gentle blow out, and air conditioning by direct blow out from the second outlet 66t. Thereby, it is possible to appropriately air condition the room R as needed. For example, if it is necessary to air condition a room in a short time period as immediately after starting air conditioning, then air conditioning can be performed in a short time period by performing air conditioning by direct blow out from the second outlet 66t. Further, after air conditioning has been performed to a certain extent, it is possible to perform comfortable air conditioning with few drafts by switching to air conditioning by radiation from the first radiation surface 54t and by gentle blow out.

Furthermore, the indoor unit 2t may be directly provided with the first outlet 65t, the second outlet 66t, and the like, instead of the switching apparatus 8t.
