Since the air after heat recovery can be used in the air conditioning system, the energy saving effect is great. Further, the stored hot water can be used for the hot water supply system system to suppress the energy consumption of the hot water supply system system and reduce the operating cost of the hot water supply system system.

とを特徴とする熱回収方法。1. A method of recovering heat accumulated near the top of an atrium having a toplight provided in a building or the like, wherein a solar shading screen is provided near the top of the atrium, and the solar shading screen and the atrium toplight are provided. Form a heat storage space surrounded by and arrange an air conditioner with a heat exchanger near the atrium,
The air introduction side of the air conditioner and the heat storage space are communicated with each other through a duct, and the air discharge side of the air conditioner and the space below the solar shading screen are communicated with each other through a duct so that the air conditioner is located near the air conditioner. A water storage tank is placed, and the storage tank and a heat exchanger provided in the air conditioner are connected by piping so that water or a heat medium can circulate, and stay in the heat storage space. The stored air is introduced into the air conditioner, and the heat exchanger of the air conditioner exchanges heat between the air introduced into the air conditioner and the water or heat medium circulated from inside the storage tank to heat the storage tank. And the air in the heat storage space is blown out to the space below the solar shading screen through the air conditioner.
