PURPOSE:To make the overall structure compact and also to improve the thermal efficiency by providing an ambient temperature collecting mechanism that introduces and ventilates the outside air by a fan which is installed in a solar heat collecting mechanism with a transparent cover attached to it, both the heat collecting mechanisms being used at the same time. CONSTITUTION:When there is sunshine, a fan 11 stays inoperative. The sunshine penetrates a transparent cover 2 and is converted into heat by being absorbed by an absorption coating 8, which is conducted in a fin 7 to vaporize and gasify the refrigerant flowing in a heat collection pipe 9. The solar heat is transferred to the refrigerant in a form of latent heat and is supplied to a condenser. Since a heat collecting plate 6 is surrounded by the transparent cover 2 and a heat isnulating material 5, a high heat collection efficiency can be maintained even when the collected temperature becomes higher than that of the outside air. If the sunshine is weakened, the fan 11 is actuated by a sensor etc., and the outside air is introduced from an inlet 13 into the collector body (a) to pass over a half of the V-shaped the heat collecting pipe 6 and then the other half, and is released from an outlet 10 by the fan 11. It is absorbed by a heat collecting pipe 9 set lower than the outside air temperature so as to enhance the thermal efficiency. |
