<p>PURPOSE: To recover air heat around a top part of a workshop during the year and improve an energy saving effect by a method wherein air in heat accumulation space is fed into an air conditioner, heat exchanged with water circulating from a storing tank and the water is accumulated as hot water and air in the heat accumulation space is blown into a space of a sun shine reflection shielding screen. CONSTITUTION: Natural light is directed into a workshop 1 and a sun shine shielding screen 3 is arranged near its top part. A space between the sun shine shielding screen 3 and a top light 2 is constructed into a heat accumulating space 4 where the heated air is accumulated. In addition, an air conditioner 5 having a heat exchanger 6 is installed outside the workshop 1, and the heat accumulating space 4 and the air conditioner 5 are communicated to each other through ducts 7, 8. Then, an accumulating tank 10 for storing water is arranged near the air conditioner 5 to cause water in the accumulating tank 10 to be circulated through water pipe 11 to return pipe 12, the water is fed into the air conditioner 5, and heat exchanging between the heated air and the liquid flowed from the accumulating tank 10 is carried out by the heat exchanger 6.</p> |
