Further, the outdoor unit 2 is provided with a propeller fan 28 for discharging the air after heat exchange in the outdoor heat exchanger 20 to the outside. The propeller fan 28 is rotationally driven by an outdoor fan motor 29.

  Hereinafter, the detailed configuration of the ceiling-mounted air conditioning indoor unit 1 will be described.

<Configuration of ceiling-mounted air conditioning indoor unit>
As shown in FIGS. 1 and 3, the ceiling-mounted air conditioning indoor unit 1 is disposed on a ceiling or the like in the room and accommodates the indoor heat exchanger 10, the indoor fan 11, the indoor fan motor 12, and the like as described above. A machine casing 4 and a radiation panel structure 5 are provided.

(Configuration of indoor unit casing)
The indoor unit casing 4 is a cassette-type casing that is installed on the ceiling surface, and has a substantially square inlet 40 and four outlets 41 corresponding to each side around the inlet 40. -44 are provided. Here, although the 1st blower outlet 41, the 2nd blower outlet 42, the 3rd blower outlet 43, and the 4th blower outlet are provided, toward the 3rd blower outlet 43 from the 1st blower outlet in FIG. A cut section is shown.

  The suction port 40 is an opening through which air taken into the indoor unit casing 4 from the room through the vicinity of the radiation panel structure 5 passes. The blower outlets 41 to 44 are openings through which conditioned air passes through the indoor heat exchanger 10 in the indoor unit casing 4 and is blown into the room again. These air flows are formed when the indoor fan 11 is rotationally driven by the indoor fan motor 12.

(Configuration of radiation panel structure)
As shown in FIGS. 1 and 3, the radiant panel structure 5 includes a flat radiant panel 50 having a flat bottom surface on the indoor side, a cold / hot water inlet 51, and a cold / hot water outlet 52. Cold and hot water is convection inside.

  The flat radiation panel 50 has a thin plate-like planar shape, and is provided in the vicinity of the ceiling surface on the indoor side of the air inlet 40 of the indoor unit casing 4 in parallel with the ceiling surface. For this reason, the flat radiation panel 50 has a larger projected area than the other directions with respect to the lower living space. In addition, since it does not have air permeability in the thickness direction from the ceiling to the room, the inhalation of room air into the indoor unit casing 4 passes through the horizontal end of the flat radiation panel 50 in the vertical direction. However, it is performed by being taken into the suction port 40.

  The cold / hot water inlet 51 and the cold / hot water outlet 52 are connected to the above-described cold / hot water temperature control device 60 so that the cold / hot water circulates. The radiant panel structure 5 a has a bag shape in which the portions other than the cold / hot water inlet 51 and the cold / hot water outlet 52 are closed by the flat radiant panel 50. Thereby, the cold / hot water adjusted to the temperature set by the cold / hot water temperature adjusting device 60 convects the inside of the flat radiation panel 50, and performs air conditioning by radiation using the heat of the cold / hot water to the room.

<Operation of air conditioner>
Next, the operation | movement operation | movement in the case of performing indoor air conditioning with this air conditioning apparatus 100 is demonstrated.

(Air-conditioning air blown by heat exchanger)
For example, during the cooling operation, the indoor heat exchanger 10 functions as an evaporator and takes heat from the passing air. The indoor air taken into the indoor unit casing 4 from the suction port 40 by the indoor fan 11 is deprived of heat when passing through the indoor heat exchanger 10 and cooled.

  As shown in FIG. 3, the cooled air is blown into the indoor space through the first air outlet 41 to the fourth air outlet 44, and the space near the air outlets 41 to 44 in the room is air-conditioned. The In the heating operation, the indoor heat exchanger 10 functions as a condenser, heats the air passing therethrough, and blows out conditioned air in the same manner, thereby air-conditioning the spaces in the vicinity of the outlets 41 to 44. .

(Radiation air conditioning from radiation panel)
For example, during the cooling operation, in the radiation panel structure 5, the cold water whose temperature is adjusted in the cold / hot water temperature adjusting device 60 flows from the cold / hot water inlet 51 and flows out from the cold / hot water outlet 52, so that the inside of the flat radiant panel 50. Convection. Thereby, air conditioning by cold radiation is performed from the lower surface of the flat radiation panel 50 to the space below the radiation panel structure 5. In the heating operation, heat radiation is performed by convection of hot water.

  Thus, in this air conditioning apparatus 100, indoor air conditioning is performed by air conditioning by blowing out conditioned air and air conditioning by radiation.

<Characteristics of the ceiling-mounted air conditioning indoor unit 1 of the present embodiment>
In a conventional air conditioner, when a flat panel structure is adopted in an air conditioning indoor unit, the conditioned air is not directly blown out directly below the flat shape, which may cause partial air conditioning shortage. In addition, if a shape such as a grill is adopted without adopting a flat structure, the design is poor.

  On the other hand, in the ceiling-mounted air conditioning indoor unit 1 according to the present embodiment, the flat radiation panel 50 of the radiation panel structure 5 has a flat bottom surface on the indoor side, and the ceiling-mounted air conditioning indoor unit 1 as a whole. Can be made a refreshing impression, and the design can be improved. And about the space around the ceiling-mounted air conditioning indoor unit 1, the comfort is improved by blowing the conditioned air through the outlets 41 to 44, and the space below the ceiling-mounted air conditioning indoor unit 1 is Comfort is improved by radiation from the flat radiation panel 50, and the interior of the room can be made comfortable overall. Thus, the design of the vicinity of the ceiling of the room can be improved while making the whole room comfortable by air conditioning by conditioned air and air conditioning by radiation.

<Other embodiments>
As mentioned above, although one Embodiment of this invention was described, this invention is not limited to the said embodiment, A various change is possible in the range which does not deviate from the summary of invention.

(A)
In the ceiling-mounted air conditioning indoor unit 1 according to the above embodiment, the flat radiation panel 50 in which the indoor side surface is formed in a flat shape has been described as an example in order to obtain a clean design.

  However, the present invention is not limited to this, and like the ceiling-mounted air conditioning indoor unit 200 shown in FIG. 4, the radiation panel has a shape protruding upward with a certain point on the indoor side as the center of the sphere. The arched radiation panel 250 may be included.

  In this case, the surface area for receiving the radiation from the cold / hot water flowing inside is wider than that in the case of the flat shape, and the radiation efficiency is improved. Furthermore, since the lower surface of the arched radiant panel 250 is formed to have an upwardly convex substantially circular arc shape, the radiation from each surface portion is particularly a space below the center of the arched radiant panel 250. Can be done towards.

  In general, the conditioned air is difficult to reach directly below the radiant panel, which may result in insufficient air conditioning. In particular, air conditioning in the space near the center of the radiant panel tends to be insufficient.

  However, due to the effect of the arch shape of the arched radiant panel 250, the air conditioning under the center of the arched radiant panel 250 can be effectively conditioned especially by radiation.

  In addition, although the arch type radiation panel 250 is not flat, it is smoothly formed so as to draw a curve with respect to the room, and therefore, the design can be maintained.

(B)
In the ceiling-mounted air conditioning indoor unit 1 according to the above embodiment, the flat radiation panel 50 in which the indoor side surface is formed in a flat shape has been described as an example in order to obtain a clean design.

  However, the present invention is not limited to this, and like the ceiling-mounted air conditioning indoor unit 300 shown in FIG. 5, the radiant panel is stepwise upward with a certain point on the indoor side as the center of the sphere. You may have the multistage arch type | mold radiation panel 350 of the protruding shape.

  In this case, the surface area for receiving the radiation from the cold / hot water flowing inside is wider than that in the case of the smooth arch shape, and the radiation efficiency is further improved. Furthermore, since the lower surface of the multi-stage arched radiant panel 350 is formed to have a substantially arc shape that is convex upward in a stepwise manner, the radiation from each surface portion is particularly the multi-stage arched radiant panel 350. It can be done towards the space below the center of the.

In general, the conditioned air is difficult to reach directly below the radiant panel, which may result in insufficient air conditioning. In particular, air conditioning in the space near the center of the radiant panel tends to be insufficient.
However, due to the synergistic effect of the staged structure of the multistage arched radiant panel 350 and the effect of the arch shape, the air conditioning under the center of the multistage arched radiant panel 350 is particularly effective due to radiation. Air conditioning is possible.

  The multi-stage arched radiant panel 350 is not flat and the surface is not smoothly formed. For example, the stepped portion of the multi-stage arched radiant panel 350 includes a plurality of concentric circles having different radii. In the case where it is viewed as an aggregate, the designability can be maintained.

(C)
In the ceiling-mounted air conditioning indoor unit 1 in the above embodiment, cold / hot water is used as a heat storage medium for the radiant panel structure 5, and the case where the temperature of the cold / hot water is adjusted by the cold / hot water temperature adjustment device 60 has been described as an example. .

  However, the present invention is not limited to this, and the heat storage medium circulated between the radiation panel structure 5 and the temperature control device is not limited to cold / hot water, and a heat storage medium such as a refrigerant may be used. In this case, the refrigerant temperature control device and the radiation panel structure 5 are connected, and the refrigerant circulates. Moreover, when using a refrigerant | coolant as a heat storage medium in this way, you may make it utilize the refrigerant | coolant currently circulating in the refrigerant circuit of an air conditioning by shunting to the radiation panel structure 5. FIG.

(D)
In the ceiling-mounted air conditioning indoor unit 1 in the above embodiment, the radiation panel structure 5 is provided on the suction side of the suction port 40 of the indoor unit casing 4 and sucks room air through the periphery of the radiation panel structure 5. The case has been described as an example.

  However, the present invention is not limited to this, and the radiation panel structure 405 is in the direction of the air flow passing through the air outlets 41 to 44 as in the ceiling-mounted air conditioning indoor unit 400 shown in FIGS. 6 and 7. It may function as a wind guide for identifying the. In this case, for example, as shown in FIG. 7, the flat radiation panel 450 of the radiation panel structure 405 is provided with an opening 440 that communicates with the upper and lower sides in the vicinity of the center so as to correspond to the suction port 40 of the indoor unit casing 4. And the edge part of a horizontal direction may be formed so that it may extend to the part exceeding the outer periphery of the blower outlets 41-44. Thereby, the radiation panel structure 405 enables suction through the suction port 40 (filter 13) of the indoor unit casing 4 through the opening 440 of the flat radiation panel 450. Moreover, each edge part of the horizontal direction of the flat radiation panel 450 is extended to the downward direction of each blower outlet 41-44 of the indoor unit casing 4, and can blow off to a room | chamber direction in a substantially horizontal direction. Thereby, it can suppress that conditioned air is blown directly with respect to the user who exists indoors, and can reduce the draft feeling which a user feels. Moreover, in the flat radiation panel 450, the edge part of a horizontal direction is extended to the downward direction of the blower outlets 41-44 of the indoor unit casing 4, and it is comprised so that each blower outlet 41-44 may be hidden when it sees from the indoor side. Yes. Thereby, the impression which looked at the ceiling installation type | formula air conditioning indoor unit 400 from the indoor side can be refreshed, and the design property can be improved.

  In general, in the conventional radiant panel, it is necessary to provide a wind guide panel or the like for adjusting the direction in which the conditioned air is blown separately from the radiant panel, and the number of parts of the apparatus is increased. On the other hand, in the ceiling-mounted air conditioning indoor unit 400 according to the other embodiment (D), a separate member for specifying the blowing direction is not required as in the prior art. Even when the air-conditioning target space is air-conditioned, an increase in the number of parts can be suppressed.

  According to the present invention, since the design can be improved even when air conditioning is performed using radiation, application to an air conditioner installed on a ceiling is particularly useful.
