(Air conditioning system air conditioning function)
Next, with reference to FIG. 2, the air conditioning function in the air conditioning system 10 of this Embodiment is demonstrated.

  The first function at the time of cooling and heating is a function of cooling and heating the room by absorbing and releasing heat by radiation and convection by the heat medium panel 20. FIG. 2 shows a cooling state. Radiation (indicated by an arrow C in FIG. 2) from a person in the room, home appliances, or the like (arrow C in FIG. 2) and convection generated in the vicinity of the heat medium panel 20 (in FIG. 2) An arrow B) shows a state in which heat is absorbed from the room.

  The second function at the time of cooling and heating is, for example, in the case of cooling, as shown by an arrow D in FIG. 2, the heat medium type panel 20 absorbs heat from the slab 5 by radiation and cools it, so-called cold heat storage. This is a function of cooling the room using the heat storage of the slab 5. Specifically, cooling is realized by exchanging heat between the air flowing through the lower flow path 40 of the slab 5 and the slab 5 and circulating this air indoors. Further, the slab 5 also absorbs heat from the room by radiation. It is effective to store heat in the slab 5 at night when the heat load of the chamber 1 is small and to use the heat storage during the daytime when the heat load of the chamber 1 becomes large. Of course, it is also possible to heat the room by storing heat in the slab 5.

  As shown by arrow F in FIG. 2, the third function at the time of cooling and heating introduces air whose temperature and humidity have been adjusted in advance to the flow path 40 on the back side of the pneumatic panel 30, and distributes this to the indoor side. This is a function for cooling and heating the room. The air introduced into the back side of the pneumatic panel 30 exchanges heat with the slab 5.

  The fourth function at the time of cooling and heating is as shown by an arrow E in FIG. 2 by introducing air whose temperature and humidity have been adjusted in advance into the chamber 31 and discharging the air through the vent hole 30a of the pneumatic panel 30. In addition, a weak air flow is generated to adjust the indoor temperature. Unlike those that actively use convection, the occupants are hardly aware that air is flowing.

  The 5th function at the time of air-conditioning is a function which air-conditions and cools a room with the radiant heat emitted from pneumatic panel 30. Since air whose temperature and humidity are adjusted flows into the back side of the pneumatic panel 30, the temperature of the pneumatic panel 30 is also controlled by the air.

  The air conditioning system 10 mainly adjusts the indoor temperature by using the above five functions.

(Effect of panel sloping wall)

Looks thin and can reduce the feeling of pressure. The panels 20 and 30 arranged continuously may have a region separated by about 10 to 40 cm as described above.

  In addition, the air heated on the window 1 b side and supplied to the back side of the air conditioning unit 11 is easily convected by the inclined walls 203, 204, 303, and 304. Further, the panels 20 and 30 having inclined walls have high rigidity such as torsion, and are easy to carry.

  In addition, this invention is not limited to the said embodiment, A various deformation | transformation is possible in the range which does not change the summary. For example, in the embodiment described above, the ceiling side is a slab, but the present invention is not limited to a slab.

  The heat medium panel and the air panel can be applied to various rooms such as hospital rooms, research rooms, offices, and gyms.

  In the above embodiment, the heat medium panel and the pneumatic panel are formed from metal, but they may be formed from other materials such as gypsum and wood, or formed from a composite material in which metal and other materials are stacked. May be.

  In the above embodiment, one or two inclined walls are provided around one panel, but three or four inclined walls may be provided around one panel.
