The cool air blown into the inside is sucked by the pump 33 and sent to the air injector 39 as the pressure feeding means 35 through the air sending guide tube 34 and the upstream flexible tube 38a. The cool air blown into the primary air inlet pipe 41 of the air injector 39 has its wind speed increased six times by the venturi 40, and
When the air is exhausted from the venturi, the outer periphery of the exhaust port of the venturi 40 has a negative pressure, and the cool air in the space 4 around the venturi 40 is sucked to form a mixed airflow. Then, the air flows into the secondary air inflow pipe 44, flows through the flexible pipe 38b on the downstream side from the one end side of each panel board 3 into the gap 12 at a high pressure, and cools each panel board 3. And furthermore, each said panel board 3

Next, the case where the room R is heated by using the all-air floor cooling / heating system of the present invention constituted as described above will be described. First, when the warm air generated by the air conditioner 30 is blown into the space 4 through the duct 31, the warm air blown into the space 4 is applied to each panel board 3 constituting the floor panel P. Is heated from the lower surface, and the hot air blown into the space portion 4 is sucked by the pump 33 and is fed by the air feeding guide tube 34 and the upstream flexible tube 38a.
Is supplied to the air injector 39 via the The warm air blown into the primary air inflow pipe 41 of the air injector 39 has its wind speed increased about six times by the venturi 40, and
When the air is exhausted from the venturi, the vicinity of the outer periphery of the exhaust port of the venturi 40 becomes a negative pressure, and the warm air in the space 4 around the venturi 40 is sucked to form a mixed airflow. From 43, the air flows into the secondary air inflow pipe 44, flows into the gap 12 from one end of each panel board 3 through the flexible pipe 38b on the downstream side at a high pressure, and heats the panel board 3. . And furthermore, each said panel board 3

Is done. Each of the panel boards 3 has a large number of hemispherical projections 16 formed in the gaps 12.
As a result, the surface area of the lower surface plate 10 in the gap 12 of the panel board 3 increases, so that the contact area with the warm air flowing into the gap 12 increases, and the temperature flowing into the gap 12 increases. The wind is turbulent and, on average, comes into contact with the inner side surface of the gap portion 12 to increase the efficiency of conduction of warm air to each panel board 3, and each panel board 3 is quickly heated, The heated state can be maintained as it is. Each panel board 3 facing the space 4
A concave portion 17 is formed on the lower surface side of the convex portion 15 on the lower surface of the panel board 3.
Is large, the contact area with the hot air flowing into the space 4 is large, and the hot air flowing into the space 4 is turbulent, and on average, each of the panel boards 3 By contacting the lower surface, the efficiency of conduction of warm air to each of the panel boards 3 is increased, and each of the panel boards 3 is quickly heated, and the heated state can be maintained as it is. And
When each panel board 3 constituting the floor panel P is heated as described above, warm air from the floor panel P is radiated into the room R to heat the room R. Further, the hot air blown into the space 4 is supplied to the slit 2 of the grill 29 provided near the wall W.

The space 4 on the lower surface of the floor panel P serves as a ventilation space for the conditioned air of the cold and hot air as described above.
It becomes a space for installing a power supply or wiring cord 46 for office equipment. If necessary, the floor material 52 is peeled off, the fastening bolts 33 are removed, and the panel board 3 at a predetermined location is opened. By removing the flexible tube 38b on the downstream side of the pumping means 35 from 45 and removing the panel board 3, inspection and repair of the cord 46 and other equipment in the space 4 can be performed. Since the present invention is as described above, the air-conditioning air of the cold / hot air of the air conditioner is fed into the space, and the air is cooled from the lower surface of each panel board constituting the floor panel. Or, while heating, the cold / hot air blown into the space is sucked by a pump, and is pumped through the pumping means to the gaps of the panel boards, and the panel boards are cooled. Further cooling and heating, the floor panel radiates cool or warm air from the floor panel to cool or heat the room, and the grill is provided with cooling / warm air conditioned air sent into the space section on the grill. Cooling and heating efficiency is good because it is combined with floor blowing cooling and heating that blows out through the slits to cool or heat the room. Further, the present invention uses only an air conditioner and does not use a cold / hot water generator as in the related art, so that the cost of cooling / heating is low and the installation space is small. Further, according to the present invention, it is possible to effectively use the space, such as arranging power supply and wiring cords for office equipment in the space, and it is possible to freely remove a panel board at an arbitrary place. Therefore, inspection and repair of the cord and other equipment can be easily performed.
