  However, in the air-conditioning apparatus disclosed in the above-mentioned conventionally known Patent Document 1, since the cold / hot water generator for generating cold water and hot water is used, there is a problem that the installation cost is high, and high air-conditioning expenses are generated. It was.

  Further, in the all-air type floor cooling and heating apparatus disclosed in the above-mentioned conventionally known Patent Document 2, since there are a large number of ventilation holes for the air-conditioning air to be blown into the room on the floor panel, something is placed on the floor. In such a case, there is a problem that a part of the small vent hole is blocked, causing a problem in air conditioning in the room.

  The present invention has been made to solve the above-described problems, and uses the air-conditioning air generated by the air conditioner to cool and heat the ceiling from the ceiling without using the cold / hot water generation as in the prior art. Therefore, it is intended to provide an all-air ceiling air conditioning system that can reduce the equipment cost.

  The present invention relates to a ventilation duct for sending cool and warm air generated by an air conditioner to a header, a header in which a flat plate made of a heat storage material is arranged, a ventilation duct for sending conditioned air from the header to a chamber, and air conditioning of the chamber The above-mentioned problem has been solved by adopting a ceiling radiation type air conditioner characterized by comprising a ceiling material having a large number of ventilation holes for blowing air into the room.

  According to the present invention, the ceiling radiation cooling and heating system that radiates cold air or warm air from the ceiling panel into the room, and the air conditioning air of the cold and hot air are blown out into the room through a large number of ventilation holes of the ceiling panel to replace the room air, The all-air ceiling cooling / heating system is configured by combining with a replacement air conditioning cooling / heating system that cools or heats the room. It is possible to provide a comfortable environment.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings.

  FIG. 1 is a schematic longitudinal sectional view showing a first embodiment of an all-air ceiling air conditioner of the present invention. That is, the all-air type ceiling air conditioner of the present invention cools or heats each panel board 1 constituting the ceiling panel P from the upper surface by the conditioned air of the cool air from the air conditioner 11 sent into each chamber 2. A ceiling radiant cooling / heating system that heats and radiates cool air or warm air from the ceiling panel P to the room R, and cool / warm air-conditioned air sent into the air supply space 3 by air pressure of the air conditioner 11 It is configured by combining with a replacement air conditioning air conditioning system that blows out from each ventilation hole 4 of each panel board 1 to the room R through each air supply space 3 and replaces it with room air to cool or warm the room R. ing.

  As shown in FIG. 2, each chamber 2 is drilled in the upper part of each panel board 1, and a connecting pipe 3 for connecting an air conditioning duct 10 for blowing air conditioning air is drilled in the chamber 2. ing.

  As shown in FIG. 3, each panel board 1 has a large number of small ventilation holes 4 at equal intervals. As shown in FIG. 4, the ceiling panel P is configured by arranging the panel boards 1 while avoiding the illumination panel 5.

  The conditioned air blown into the chamber 2 has a radiation effect into the room R from the entire lower surface of the ceiling panel P constituted by each panel board 1. In addition, since the air-conditioning air is blown into the room R through the numerous ventilation holes 4 formed in the panel board 1, there is a synergistic effect of the radiation effect from the ceiling panel P and the convection effect of the air-conditioning air blown into the room R. can get. The perspective view from the lower surface of the Example of the ceiling panel part of the all air system ceiling air conditioner of this invention is shown in FIG.

  Air-conditioned air from the air conditioner 11 is blown into the header 7 through the ventilation duct 6. As shown in FIG. 6, the header 7 has a function of evenly supplying air-conditioned air to the air-conditioning ducts 10. Inside the header 7, as shown in FIG. 7, a heat storage plate 9, which is a flat plate made of an animal heat material, is drilled. The air-conditioned air sent into the header 7 is evenly diffused by hitting the heat storage plate 9.

  The heat storage plate 9 made of animal heat material has the effect of storing the heat of the air-conditioning air as latent heat. As an example, during cooling, the heat of about 15 ° C. is stored as latent heat, and air of about 15 ° C. is sent to each air conditioning duct 10 to keep the surface temperature of each panel board 1 at about 20 ° C. without drastically lowering the surface temperature. Have

  At the same time, when the air conditioner 11 is stopped by the room temperature sensor 12, the air of about 26 ° C. to 28 ° C., which is the same as the room temperature, hits the heat storage plate 9 formed in the header 7 through the ventilation duct 6, and the heat storage plate The air is absorbed by the air 9 to cool each panel board 1, and the air is blown into the room R through a number of ventilation holes 4 formed in each panel board 1. This has the effect of stabilizing the temperature of the air blown into the room R.

  FIG. 8 is a schematic longitudinal sectional view showing a second embodiment of the all-air ceiling air conditioner of the present invention. In the first embodiment, the heat storage plate 9 is drilled in the header 7, but in the second embodiment, no heat storage plate is drilled in the header 7. In each of the chambers 2, a plurality of animal heat plates 9 are formed. A cross-sectional view of each chamber portion is shown in FIG. In the second embodiment, since the heat storage plate 9 is formed in each chamber 2 adjacent to each panel board 1, the effect of the latent heat storage of air on each panel board 1 is further enhanced. Can do.

  The present invention is used in the industrial field of air conditioning systems and air conditioning systems.
