PURPOSE:To reduce the component parts and installation cost by utilizing a space communicating the upper and lower floors as a duct so that a duct for return air recirculation may become unnecessary. CONSTITUTION:An air conditioner 1 utilizing the solar heat has a duct 3 that is communicating a pneumatic solar heat collector 2 and rooms R1, R2, and an air outlet 4 of the rooms R1, R2 and an air inlet 5 of the solar heat collector 2 are connected by a space S that is communicating the upper and lower floors. Therefore, upon the operation of a fan F, the warm air generated in the solar heat collector 2 can be delivered from the air outlet 6, duct 3 and air inlets 7, 8 to the room R1, room R2 and a heat accumulating tank C, while the air so delivered flows in the space S from the air outlets 4, 4 as the return air, which moves upward in the space S and is recirculated to the solar heat collector 2 via a duct 29 and the air outlet 5. |
