Description

  The present invention relates to a radiation type air conditioner provided on a ceiling.

  The air conditioner may be uncomfortable for a person when the cold air or hot air blown from the air conditioner directly hits the air conditioner. On the other hand, there is an air conditioner in which cold water or hot water as a heat medium cools or heats a radiation panel. In this case, the cooled panel absorbs far infrared rays, or the heated panel emits far infrared rays, thereby cooling and heating. However, this has a problem that equipment for circulating cold water or hot water is necessary. In addition, it is said that not only radiant heat generated by far infrared rays but also the human skin needs to come into contact with some cold air in order to feel comfort. However, such an air conditioner that absorbs or emits far infrared rays has a problem that cold air that directly touches the skin is not generated.

  In view of this, there has been proposed a radiant air conditioner in which cold air produced by an air conditioner is used as a heat medium and the radiant panel is cooled or heated while discharging the cold air into the room. For example, in the radiation panel unit and the radiation type air conditioner described in Patent Document 1, a radiation panel is suspended from the ceiling, and a space between the radiation panel and the ceiling is used as a cooling air passage. A number of slit holes are provided in the radiation panel. The cool and warm air produced by the air conditioner is discharged into the room through a slit hole opened there while cooling or heating the radiation panel. The air released into the room is again taken into the air conditioner and cooled or heated.

[First Embodiment]
Based on FIG. 4, the radiation type air conditioner A1 according to the first embodiment of the present invention will be described. The radiation type air conditioner A1 is installed by being suspended so as to be in close contact with a ceiling member formed of a heat insulating member. A heat insulating member may be attached to the lower surface of the normal ceiling member, that is, the side facing the living space, and the radiant air conditioner A1 may be installed below the heat insulating member. That is, the upper wall surface of the radiant air conditioner A1 uses a ceiling member having a heat insulating property as it is, or has a structure in which an upper surface is formed of a heat insulating member.

  A part of the heat insulating ceiling member C on which the radiant air conditioner A1 is installed forms the upper wall surface 11 of the radiant air conditioner A1. In the heat-insulating ceiling member C, linear mounting brackets 111 and 112 are fixed in parallel so as to surround the upper wall surface 11 (FIG. 4D). Further, the upper wall surface 11 is provided with a temperature-controlled air inlet 12 for introducing air whose temperature is adjusted by an air conditioner AC (not shown) (hereinafter referred to as temperature-controlled air) [FIG. 4D]. As shown in FIG. 4D, the upper wall surface 11 is surrounded by a rectangular shape in which two linear mounting brackets 111 that are parallel to the heat-insulating ceiling member C are fixed and these are parallel to two sides. It is an area.

  The bottom surface 2 and the side surface 22 of the radiation type air conditioner A1 are composed of a radiation panel 21 formed of a metal plate. The radiation panel 21 has side surfaces 22 formed at both ends thereof fixed to the heat insulating ceiling member C. The side surface 22 is formed by raising both ends of the radiation panel 21 substantially vertically. The side surface 22 is bolted with a mounting bolt 222 to a mounting bracket 111 fixed to the heat insulating ceiling member C. The radiation panel 21 is suspended and fixed to the heat insulating ceiling member C by this bolting. The side surface 22 connects between the bottom surface 2 and the heat insulating ceiling member C, and is located higher than the bottom surface 2 (FIG. 4A).

  Here, for convenience of explanation, a direction and a direction are determined. On the surface where the both side surfaces 22 and 22 are fixed to the lower surface of the heat insulating ceiling member C, the long direction of the ground contact surface between the heat insulating ceiling member C and the side surface 22 will be referred to as the Y direction. And on the lower surface of the heat insulating ceiling member C, the direction orthogonal to the Y direction will be referred to as the width direction or the X direction. Moreover, the direction orthogonal to the heat-insulating ceiling member C is referred to as the vertical direction or the Z direction, and the downward direction is the positive direction (see FIG. 4).

  The radiation panel 21 is made of a metal such as aluminum. In FIG. 4, both sides in the X direction of the radiation panel 21 are fixed to the heat insulating ceiling member C via the side surfaces 22. For this reason, the upper wall surface 11 which is a part of the heat insulating ceiling member C and the radiation panel 21 form a space having openings at both ends in the Y direction. These openings can be closed by the lid body 24. The lid body 24 includes two lid side parts 241 a and 241 b and a lid center part 242. The lid body 24 has substantially the same shape as the opening at both ends in the Y direction, and has a shape suitable for closing the opening.

  An air passage D (not shown) is formed in the radiant air conditioner A <b> 1 by the upper wall surface 11 and the radiant panel 21 that constitutes the bottom surface 2 and the side surface 22. The air passage D is a space for circulating temperature-controlled air. In the example of FIG. 4D, the air passage D is formed by installing the upper ends of the side surfaces 22 formed at both ends of the radiation panel 21 one by one on the mounting bracket 111.

  However, in this state, the air passage D is formed with openings having the same cross-sectional shape at both ends in the direction in which the mounting bracket 111 extends, that is, in the Y direction. The aforementioned lid 24 is a lid having the same shape as the shape of the opening. Since the two openings formed at both ends in the Y direction are respectively closed by the lid body 24, the air passage D becomes a closed space inside the radiant air conditioner A1.

  However, the air passage D is not a sealed space. The side surface is provided with a discharge hole 221 which is a through hole. The temperature-controlled air Air-A sent into the air passage D from the temperature-controlled air introduction port 12 provided in the upper wall surface 11 circulates in the air passage D and then passes through the discharge holes 221 to the outside of the air passage D. Is released. That is, the temperature-controlled air Air-A is discharged into the living space through the discharge hole 221. Moreover, the discharge hole 243 can also be provided in the two lid side parts 241a and 241b. In this case, the temperature-controlled air Air-A is also discharged from the discharge holes 243 to the outside of the air blowing path D.

  As shown in FIGS. 4D and 4E, partition plates 25a and 25b are provided on the inner side of the radiation panel 21, that is, on the air passage D side. The two partition plates 25a and 25b that are arranged in the X direction and extend in the Y direction divide the air blowing path D into three blowing spaces Da, Db, and Dc extending in the Y direction. However, these partition plates 25a and 25b are provided with through-holes called a circulation port 25a1 or a circulation port 25b1, respectively. For this reason, the temperature-controlled air can freely travel between the three ventilation spaces Da, Db, and Dc.

  Thus, by providing the partition plates 25a and 25b that can be moved back and forth in the air passage D, the flow of the temperature-controlled air Air-A is disturbed, and the temperature-controlled air Air-A is strongly blown to the radiation panel 21. Can be. By adopting such a configuration, heat exchange can be efficiently performed between the temperature-controlled air Air-A and the radiation panel 21.

<Operation during cooling>
When the living space is cooled by the radiation type air conditioner A1, the temperature-controlled air Air-A cooled by the air conditioner AC is introduced into the air passage D. The cooled temperature-controlled air Air-A exchanges heat with the radiation panel 21 while circulating in the air passage D. The radiation panel 21 is cooled by heat exchange. In exchange for this, the temperature-controlled air Air-A itself is slightly warmed. Slightly warmed temperature-controlled air Air-A is gradually discharged into the living space through the discharge holes 221 and 243.

  In the living space, the temperature of the radiation panel 21 installed on the lower surface of the ceiling is low. For this reason, the radiation of the far infrared rays from the radiation panel 21 to the person in the living space is suppressed to a small size, and the cooling effect is exhibited. Further, the temperature-controlled air that is gradually discharged into the living space through the discharge holes 221 and 243 brings about a quiet fluctuation of the air, and makes people in the living space feel comfortable.

<Operation during heating>
When the living space is heated by the radiation type air conditioner A1, the temperature-controlled air Air-A heated by the air conditioner AC is introduced into the air blowing path D. The heated temperature-controlled air Air-A heats the radiation panel 21. When the heated temperature-controlled air Air-A touches the radiation panel 21, dew condensation water may be generated inside the air blowing path D. Even in such a case, since the discharge holes 221 and 243 are located higher than the bottom surface 2, the condensed water does not fall into the living space.

  This temperature-controlled air Air-A exchanges heat with the radiation panel 21 while circulating in the air passage D. The radiation panel 21 is heated by heat exchange. In exchange for this, the temperature-controlled air Air-A itself is slightly cooled. Slightly cooled temperature-controlled air Air-A is gradually discharged into the living space through the discharge holes 221 and 243. Far infrared rays are irradiated into the living space from the heated radiation panel 21. Thereby, the person in the living space feels warmth. Further, the temperature-controlled air discharged from the discharge holes 221 and 243 in a moderately cooled state creates a quiet fluctuation, and realizes comfortable heating in the living space.

  Moreover, as shown in FIG.4 (E), you may apply | coat or affix the diatomaceous earth member 23 to the outer side of the radiation panel 21, ie, the side suitable for a living space. The diatomaceous earth member 23 is a member that absorbs moisture. With this configuration, even when dew condensation occurs on the outer surface of the radiant air conditioner, that is, the radiant panel surface that does not face the air passage, the diatomaceous earth member that covers the radiant panel surface absorbs moisture. It has the effect of not falling. An example of the diatomaceous earth member is a diatomaceous earth cloth which is a wallpaper using diatomaceous earth.

  Moreover, as shown to FIG.4 (E), it is good also as a radiation panel shape which gave the bulge a little on the outer side of the radiation panel 21, ie, the side suitable for living space. By setting it as such a structure, since a far infrared ray spreads radially toward the said living space, it becomes possible to receive the radiation of the said far infrared ray in a wide range. Further, the surface of the radiation panel 21 may be embossed as described later. If it does in this way, the surface area of the radiation panel 21 surface will be increased, and the radiation efficiency as a radiation panel will be improved.

[Second Embodiment]
Next, based on FIG. 5, the radiation type air conditioner A2 which concerns on 2nd Embodiment of this invention is demonstrated. In the radiant air conditioner A2, a temperature-controlled air inlet 12 is provided on the upper wall surface 11B, and an air passage D2 (not shown) is formed by the upper wall surface 11B, the radiant panel 21B, and the lid body 24. And the side 22 is formed in the part currently fixed to the heat insulation ceiling member C at the both ends of the radiation panel 21B.

  This configuration is the same as the configuration of the radiant air conditioner A1 according to the first embodiment. Further, in the radiant air conditioner A2 according to the second embodiment, what should be called the indoor air circulation pipe 3 penetrates between the upper wall surface 11B and the radiant panel 21B. This is because the air Air-B in the living space that spreads under the radiation panel 21B is sucked from the indoor air suction port 13 provided on the upper wall surface and sent to the air conditioner AC [broken line at the top of FIG. 5 (B)]. It is a flow passage.

  With such a configuration, it is convenient to install the air conditioner AC for producing the temperature-controlled air Air-A directly behind the radiant air conditioner A2, and a compact system can be constructed. The air conditioner AC sucks the air Air-B in the living space through the indoor air circulation pipe 3. And this air Air-B is sent to the ventilation path D2 as temperature control air introduction port 12 as temperature control air. Since the inner wall 31 of the indoor air circulation pipe 3 also serves as a side wall constituting the air passage D2, the temperature-controlled air Air-A is sucked again from the indoor air inlet 13 before circulating in the living space. There is nothing.

  FIG. 5B is a perspective view looking up at a state in which the radiation panel 21B is removed from the heat insulating ceiling member C. FIG. Side surfaces 22 formed at both ends of the radiation panel 21 </ b> B are bolted to the mounting bracket 111. The lid body 24 is fitted between the radiation panel 21 </ b> B and the mounting bracket 112. A region surrounded by the mounting brackets 111 and 112 fixed to the heat insulating ceiling member C forms an upper wall surface 11B. The upper wall surface 11B is provided with a temperature-controlled air inlet 12 and an indoor air inlet 13.

  When this upper wall surface 11B is covered with a radiation panel 21B integrated with the indoor air circulation pipe 3, the air Air-B in the living space is sucked from the indoor air suction port 13, and the air passage from the temperature control air introduction port 12 Temperature-controlled air Air-A is sent to D2. The temperature-controlled air Air-A sent into the air passage D2 exchanges heat with the radiation panel 21B, and is then discharged from the discharge holes 221 and 243 (see FIG. 5A) into the living space. That is, the temperature-controlled air Air-A is released to the outside of the air blowing path D2.

  Partition plates 26a and 26b extending in the Y direction across the indoor air circulation pipe 3 are provided on the inner side of the radiant panel 21B, that is, on the air blowing path D2 side. The partition plates 26a and 26b and the indoor air circulation pipe 3 divide the air passage D2 formed inside the radiation panel 21C2 into four air spaces Da and Db and two Dd. There is no circulation port in the indoor air circulation pipe 3, and the two ventilation spaces Dd and Dd are isolated.

  The inner side of the indoor air circulation pipe 3 is the inner wall 31 of the circulation pipe that is in contact with the air Air-B in the living space, as already described. On the other hand, distribution ports 26a1 and 26b1 are provided in the partition plates 26a and 26b, respectively, so that the temperature-controlled air Air-A can go back and forth. As shown in FIG. 5A, an annular structure is formed in which two Dd bridge between the air blowing spaces Da and Db that exist after being separated.

  FIG. 5C is an end view taken along arrow X2-X2 in FIG. The temperature-controlled air Air-A supplied from the air conditioner AC installed on the heat-insulating ceiling member C is introduced into the blower spaces Da and Db through the temperature-controlled air inlet 12. The temperature-controlled air introduced into Da and Db circulates through the air passage D2 through the air blowing spaces Dc1 and Dc2, and exchanges heat with the radiation panel 21B. Thereafter, the temperature-controlled air Air-A is discharged from the discharge holes 221 and 243 to the living space.

  Further, by performing so-called embossing, which provides unevenness on the surface like the radiant panel 21B2, the surface area can be increased and the radiant efficiency as the radiant panel can be improved (see FIG. 5D). Furthermore, regardless of whether or not embossing is performed, the indoor air circulation pipe 3 may be covered with a circulation pipe lid 32 that ensures air permeability with a punching hole or the like (see FIG. 5D).

[Third Embodiment]
Next, based on FIG. 1, the radiation type air conditioner A3 which concerns on 3rd Embodiment of this invention is demonstrated. The radiation type air conditioner A3 includes a radiation panel 21C. The radiation panel 21C is composed of three radiation panels 21C1, 21C2 and 21C3, and these are suspended and fixed to the heat insulating ceiling member C. An air conditioner AC is installed above the radiation panel 21C2 with the heat insulating ceiling member C interposed therebetween.

  Then, the air conditioner AC sucks the air Air-B in the living space through the indoor air suction port 13, and cools or heats the air Air-B to obtain temperature-controlled air Air-A [see FIG. 1 (C)]. And the temperature control air Air-A is introduce | transduced into the ventilation path D3 (not shown) mentioned later through the temperature control air inlet 12 which is not shown in figure. Temperature-controlled air Air-A introduced into the air passage D3 is discharged into the living space from the discharge holes 221 provided in the side surface 22 after heat exchange with the radiation panel 21C1, 21C2, and 21C3. Furthermore, a discharge hole 243 may be provided in the lid 24.

  The radiation panel 21C1 and the radiation panels 21C2 and 21C3 are curved surfaces having curves that slightly swell toward the living space along the X direction. And in the center of radiation panel 21C2 located directly under air-conditioner AC, the opening used as the entrance of indoor air circulation pipe 3 which is a through-hole is provided. And between the opening and the heat insulation ceiling member C, the distribution pipe inner wall 31 is continuing, and the ventilation path D3 which is the inside of radiation type air conditioner A3, and the living space are separated.

  When the radiant air conditioner A3 installed on the heat-insulating ceiling member C is looked up from below, the indoor air inlet 13 provided on the upper wall surface 11C can be seen through the indoor air circulation pipe 3 [FIG. 1 (B1 ) And (C)]. However, the opening serving as the inlet of the indoor air circulation pipe 3 may be covered with a plate in which ventilation is ensured, for example, a punching metal.

  FIG. 2A is a perspective view of a state in which the radiation panel 21C1 and the radiation panels 21C2 and 21C3 are removed from the heat-insulating ceiling member C on which the radiation type air conditioner A3 is installed. Each of the radiation panel 21C1 and the radiation panels 21C2 and 21C3 rises upward in the X direction (also referred to as the width direction) to form a side surface 22. The radiant panel 21C1 and the radiant panels 21C2 and 21C3 are suspended and fixed to the heat insulating ceiling member C by bolting the side surface 22 to the mounting bracket 111 fixed to the heat insulating ceiling member C.

  In the heat-insulating ceiling member C, an area surrounded by the mounting brackets 111 and 112 fixed to this is the upper wall surface 11C. The upper wall surface 11C is provided with an indoor air inlet 13 through which the air conditioner AC sucks air Air-B in the living space, and a temperature-controlled air inlet 12 through which the temperature-controlled air Air-A from the air conditioner AC is blown out. Yes. When the radiation panel 21 </ b> C <b> 2 is installed on the heat insulating ceiling member C, the indoor air suction port 13 is accommodated in the opening of the indoor air circulation pipe 3. Therefore, the indoor air suction port 13 comes into direct contact with the air Air-B in the living space through the indoor air circulation pipe 3.

  When the radiation panel 21C1 and the radiation panels 21C2 and 21C3 are installed on the heat insulating ceiling member C, these radiation panels are in close contact with each other, and the gap is eliminated. The openings opened at both ends in the Y direction are closed by the lid body 24. The lid 24 is fitted between the end of the radiation panel 21C1 or 21C3 and the mounting bracket 112.

  The radiant air conditioner A3 (see FIG. 1) according to the third embodiment removes the lids 24 attached to both ends of the radiant air conditioner A2 (see FIG. 5) according to the second embodiment, and the lid 24 It can be seen that the radiation panels 21C1 and 21C3 are added to the opening that has been closed. That is, two linear installation fittings 111 parallel to the heat-insulating ceiling member C are fixed, and a region surrounded by a rectangular shape having the installation fittings 111 as two parallel sides is set. Further, the parallel installation brackets 111 for extension are fixed so as to extend to one end of the parallel installation brackets 111. In this way, the entire area obtained by adding the area surrounded by the rectangular shape having the two mounting brackets 111 in parallel to the rectangular shape to the left area can be considered as the upper wall surface 11C.

  And the radiation panel 21C1 or the radiation panel 21C3 is formed so as to be adjacent to the radiation panel 21C2 in FIG. 2 (A), which forms the same air passage as the radiation type air conditioner A2 (see FIG. 5) according to the second embodiment. Install. For example, the upper ends of the side surfaces 22 formed at both ends of the radiation panel 21C1 are installed one by one on the additional installation bracket 111, respectively.

  As a result of this construction, an opening with the same cross-sectional shape is formed in the expanded air passage formed by the expanded upper wall surface and the radiation panel 21C1 in the direction in which the expansion mounting bracket 111 extends, that is, in both ends in the Y direction. Each will be formed. And the opening which the radiation panel 21C2 comprises, and the opening which the radiation panel 21C1 comprises adjoining this are airtightly connected, The ventilation path expanded and expanded is implement | achieved. Similarly, by expanding the radiation panel 21C3, the expanded and expanded air passage D3 is finally realized.

  FIG. 2B is a perspective view of the state in which the radiation panel 21C1 and the radiation panels 21C2 and 21C3 are removed from the heat insulating ceiling member C on which the radiation type air conditioner A3 is installed, as viewed from above. Partition plates 27a and 27b extending in the Y direction are provided inside the radiation panel 21C1 and the radiation panel 21C3, that is, on the side facing the air passage D3.

  As shown in FIG. 3A, the partition plates 27a and 27b divide the air blowing path D3 formed inside the radiation panel 21C1 and the radiation panel 21C3 into three air blowing spaces Da, Db, and Dc. However, the flow outlets 27a1 and 27b1 are provided in the partition plates 27a and 27b, respectively, so that the temperature-controlled air Air-A can come and go.

  As shown in FIG. 3A, the indoor air circulation pipe 3 passes through the center of the radiation panel 21C2. In addition, partition plates 27c and 27d extending in the Y direction with the indoor air circulation pipe 3 interposed therebetween are provided on the inner side of the panel, that is, on the side facing the air passage D3. The partition plates 27c and 27d and the indoor air circulation pipe 3 divide the air passage D3 formed inside the radiation panel 21C2 into four air spaces Da and Db and two Dd.

  There is no circulation port in the indoor air circulation pipe 3, and the two ventilation spaces Dd and Dd are isolated. The inner side of the indoor air circulation pipe 3 is the inner wall 31 of the circulation pipe that is in contact with the air Air-B in the living space, as already described. On the other hand, distribution ports 27c1 and 27d1 are provided in the partition plates 27c and 27d, respectively, so that the temperature-controlled air Air-A can go back and forth [FIG. 3 (A)].

  Further, when the radiation panels 21C1, 21C2, and 21C3 are in close contact with each other, all the air blowing spaces Da are integrated and all the air blowing spaces Db are also integrated. The ventilation spaces Dc and Dd are also integrated. Through the circulation ports 27a1, 27b1, 27c1 and 27d1, the temperature-controlled air Air-A can go back and forth in all the air blowing spaces. The air passage 3 </ b> D is formed as an annular air passage around the indoor air circulation pipe 3.

  Returning to FIGS. 2A and 2B, the description will be continued. The temperature-controlled air inlet 12 provided in the upper wall surface 11C is located on the upper wall surfaces of the blowing spaces Da and Db of the radiation panel 21C2. Therefore, the temperature-controlled air Air-A produced by the air conditioner AC is first introduced into the blowing spaces Da and Db of the radiation panel 21C2 via the temperature-controlled air introduction port 12. The temperature-controlled air Air-A exchanges heat with the radiation panel 21C while circulating around the annular air passage D3, and is gradually discharged from the discharge hole 221 into the living space.

  The air passages D, D2 and D3 of the radiant air conditioner according to the first to third embodiments of the present invention introduce the temperature-controlled air Air-A from the air conditioner AC from the temperature-controlled air inlet 12, It discharges from the discharge hole 221 to the living space. Therefore, in order not to raise the pressure in these ventilation paths too much, the opening area of the discharge holes is secured so as to ensure a discharge amount equal to or more than the blown amount per unit time introduced from the temperature-controlled air inlet 12. Should be determined. That is, when the opening area of each discharge hole is large, the total number of discharge holes can be reduced. On the other hand, when reducing the opening area of the discharge holes, it is necessary to increase the total number of discharge holes accordingly.

  In the first to third embodiments of the present invention, the radiation panels 21, 21B, 21C1, 21C2, and 21C3 are formed of thin aluminum plates [FIGS. 4E, 5C, and D], (See FIGS. 3B, 3C, and 3D). The partition plates 25a, 25b, 26a, 26b, 27a, 27b, 27c and 27d, which are internal structures, are formed by bending a part of an aluminum thin plate constituting the radiation panel.

  These partition plates are provided with circulation ports 25a1, 26a1, 27a1, 27d1 and the like as appropriate. This has a structure in which a metal screen is also provided inside the metallic radiation panel. By adopting such a structure, the temperature-controlled air Air-A that circulates through the air passage D, D2, or D3 frequently hits the partition and causes a turbulent flow, and the efficiency between the temperature-controlled air Air-A and the radiation panel is increased. Thus, heat exchange is performed.

<Flexible compatibility from small to large residential spaces>
The radiation type air conditioner of the present invention is excellent in adaptability that can be flexibly adapted from a small-scale living space to a large-scale living space as described below. For example, the radiation type air conditioner according to the first embodiment and the second embodiment is composed of a radiation unit of the minimum unit and can be installed in a small living space. In particular, in the radiant air conditioner A2 according to the second embodiment, if the air conditioner AC is provided above the radiant panel 21B, a pipe for sending air between the air conditioner AC and the living space can be shortened.

  Moreover, as can be seen in the radiation type air conditioner A <b> 3 according to the third embodiment, both ends of the device are closed by the lid body 24. If the lid 24 is omitted and the radiant panel 21C1 or 21C3 is additionally provided, the area of the radiant panel can be expanded. In this way, it is possible to construct a small-scale air conditioner to a large-scale air conditioner according to the ceiling area of the living space.

FIG. 6 omits the radiation panel 21C1 of the radiation type air conditioner A3 according to the third embodiment, and the radiation panel which is a view looking up at the lower surface of the heat insulating ceiling member on which 21C2 and 21C3 are to be installed. FIG. 2A is a view showing a temperature-controlled air inlet 12, an indoor air inlet 13, and a partition adapted to this. And (B) is a figure which shows the temperature control air inlet 12B of another shape, the indoor air inlet 13B, and the partition fitted to this.

  In the example described so far, the indoor air inlet 13 that is the inlet of the air conditioner AC and the temperature-controlled air inlet 12 that is the outlet of the air conditioner AC are as shown in FIG. That is, a substantially rectangular temperature-controlled air inlet 12 that is long in the Y direction is provided on the lower surface of the heat insulating ceiling member C in parallel. And two indoor air inlets 13 provided in parallel are provided inside two temperature-controlled air inlets 12 provided in parallel. In the figure, the temperature-controlled air inlet 12 and the indoor air inlet 13 communicate with the air outlet and the inlet of the air conditioner AC installed on the upper surface of the heat insulating ceiling member C, respectively.

  Here, the temperature-controlled air Air-A introduced from the temperature-controlled air inlet 12 to the air passage D3 (not shown) and the air Air-B of the living space sucked into the air conditioner AC from the indoor air inlet 13 are provided. It is necessary to be isolated so as not to mix. Therefore, as already described, the inner wall 31 of the circulation pipe, which is the inner wall of the indoor air circulation pipe 3, and the isolation wall composed of the partition plates 27c and 27d are configured.

  Moreover, as shown to FIG. 6 (B), according to the shape of the blower outlet of the air-conditioner AC, and the inlet port, the heat-insulating ceiling member C should be provided with the temperature control air inlet 12B and the indoor air inlet 13B. There is also. That is, a substantially square indoor air inlet 13B is provided at the center. Two temperature-controlled air inlets 12B that are long in the X direction are arranged in parallel, and the indoor air inlet 13B is sandwiched from both sides. Further, two temperature-controlled air inlets 12B that are long in the Y direction are arranged in parallel, and the indoor air inlet 13B is sandwiched from both sides.

  Here, the temperature-controlled air Air-A introduced from the temperature-controlled air introduction port 12B into the air passage D3 (not shown) and the air Air-B in the living space sucked into the air conditioner AC from the indoor air intake port 13B. It is necessary to be isolated so as not to mix. Therefore, a flow pipe inner wall 31B which is an inner wall of the indoor air flow pipe 3B and an isolation wall made up of the partition plates 27c and 27d are configured. Thus, in order to adapt to the variation of the inlet and outlet of the air conditioner, the partition wall that separates the temperature-controlled air Air-A and the air Air-B of the living space should be designed as appropriate.

[Fourth Embodiment]
Next, based on FIG. 7, the radiation type air conditioner A4 according to the fourth embodiment of the present invention will be described. The radiation panel 21 </ b> D made of metal is installed and fixed on the lower surface of the heat insulating ceiling member C. You may install using the mounting brackets 111 and 112 similarly to the 1st thru | or 3rd embodiment. With this configuration, the upper wall surface 11D of the radiation type air conditioner A4 (hidden from the radiation panel 21D and cannot be seen) is formed of a heat insulating member. When the radiation type air conditioner A4 is installed on a ceiling without heat insulation, the upper surface plate of the heat insulation member may be the upper wall surface 11D. For example, a vinyl chloride resin can be applied to the upper surface plate of the heat insulating member.

  In the radiant air conditioner A4 having such a configuration, the upper wall surface 11D and the radiant panel 21D form a blower passage D4 for blowing the temperature-controlled air Air-A. However, in FIG. 7, illustration of D4 is omitted. The radiation panel A4 constitutes a bottom surface 2D and a side surface 22D. The side surface 22D is provided with a discharge hole 221D for discharging the temperature-controlled air Air-A introduced into the blower passage D4 to the outside of the blower passage D4 in a horizontal direction.

  Further, the upper wall surface 11D and the radiation panel 21D form openings having the same shape at both ends in the Y direction, but these openings are closed by the cover body 24D having the same shape. The lid body 24D may also be provided with a discharge hole 243D that discharges the temperature-controlled air Air-A to the outside of the blower path D4. The upper wall surface 11D is provided with a temperature-controlled air inlet 12 and an indoor air inlet 13. However, the temperature-controlled air inlet 12 is hidden by the radiation panel 21D and cannot be seen. The temperature-controlled air Air-A is introduced into the air passage D4 (not shown) from the air conditioner AC (not shown) installed on the upper surface of the heat insulating ceiling member through the temperature-controlled air inlet 12.

  The air conditioner AC may be provided with a suction port in any of the living spaces, but the indoor air suction port 13 can be provided on the upper wall surface 11D like the radiant air conditioner A4. In this case, in order to distribute the air Air-B in the living space to the indoor air suction port 13, it is necessary to provide the indoor air circulation pipe 3 penetrating between the upper wall surface 11D and the radiation panel 21D. With such a configuration, it is not necessary to provide an indoor air intake port by the air conditioner AC at any location away from the radiant air conditioner A4.

  In the radiation panel 21D of the radiation type air conditioner A4, the bottom surface 2D and the side surface 22D are smoothly continuous and have no boundary. However, since the discharge hole 221D provided in the side surface 22D is located higher than the bottom surface 2D, even if dew condensation occurs in the air passage D4, the dew condensation water does not fall into the living space through the discharge hole 221D.
