PURPOSE:To increase the heat collecting amount of air per unit sunshine heat receiving area by a method wherein a heat collecting unit is constituted so as to be a fin tube type in which heat collecting fins are laminated in the axial direction of heat collecting tubes with specified spaces and the space between the heat collecting tubes is specified to a specified value. CONSTITUTION:The device is provided with a refrigerant enclosing circuit, in which a compressor 1, a condenser 2, an expansion valve 3 and the heat collecting unit 4 collecting the heats of the sun and air are connected sequentially, and a hot-water supplying circuit, in which a water heater 5 having the condenser 2 and a heat exchanging means, a hot-water reserving tank 6 and a water circulating pump 7 are connected, while the heat collecting unit 4 is constituted so as to be the fin tube type, in which the heat collecting fins 4b are laminated in the axial direction of the heat collecting pipes 4a with spaces of 4-6mm. and the spaces between the heat collecting pipes 4a are determined so as to be 40-60mm.. As a result, the heat collecting amount of air per unit sunshine heat receiving area is increased, the heat collecting unit is miniaturized and a space for mounting the unit is reduced. The heat absorbing amount of air and the efficiency of heat collecting operation become maximum when no wind is blowing at outside of a house. |
