冬期夜間の運転は行なわない。 In this state, indoor air (25°C x 50%) is taken into the air conditioner 4 through the inlet 35, and the dehumidifier 1 receives LiCl solution (34°C) dropwise to dehumidify this air and simultaneously raise the temperature. and obtain 30℃ x 30% air. At this time, the Licl solution is diluted and the temperature is lowered to 32°C. The air (30°C x 30%) exiting the dehumidifier 1 passes through the heat exchanger 2 and is sent to the outlet 33. is sent to the air passage 25 of the solar heat collector 5, where it absorbs solar heat and is heated up, and is humidified by taking away the moisture in the Licl solution. Air is supplied. On the other hand, the Licl solution obtained by humidifying and dehumidifying the return air in the dehumidifier 1 and diluting it at a low temperature passes through the heat exchanger 3 and accumulates in the receiving tank 11, and is returned to the heat storage tank 6. From 27, the entire amount enters the flow path 24 of the solar heat collector 5, where it absorbs solar heat and is heated. At the same time, the air flowing through the air path 25 removes moisture and is regenerated. The LiCl solution is sent to the liquid dispersion tank 9. In addition,
