However, in such a conventional heat collector of the heat collecting apparatus, the evaporation temperature of the refrigerant in the heat collection section must be set lower than the atmospheric temperature, so that the evaporation temperature and the condensation temperature are reduced. The temperature difference from the temperature increases, and the power consumption of the compressor consumed to obtain the same amount of heat increases. For this reason, it is conceivable to raise the evaporation temperature above the atmospheric temperature to reduce the power consumption of the compressor. As an example of this, a case in which a heat collecting portion is provided in a box whose upper surface is made of translucent glass is used. In this case, since the condensed refrigerant is almost completely evaporated by solar heat, there is a disadvantage that a large heat collector is required if the evaporation temperature is to be higher than the atmospheric temperature.

[0004] The present invention has been made in view of such a point, and until the condensed refrigerant is raised to the atmospheric temperature, the heat can be collected by the atmospheric heat even without the use of sunlight. It is an object of the present invention to provide a heat collecting device that can increase the evaporation temperature without increasing the size of the heat collecting device and reduce the power consumption of the compressor by providing an atmospheric heat collecting device on the back surface of the heat collecting device.

[0006] The provision of the atmospheric heat collecting portion on the back side of the solar heat collecting portion does not increase the size of the heat collector. In addition, since the flow direction of the refrigerant is caused to flow from the atmospheric heat collecting section to the solar heat collecting section, the refrigerant is once raised to the atmospheric temperature by the atmospheric heat collected by the atmospheric heat collecting section, and the temperature is increased. By sending the refrigerant to the solar heat collector and further heating it with sunlight, the evaporation temperature of the refrigerant can be higher than the atmospheric temperature, and the refrigerant can be efficiently heated to a higher temperature.
