PURPOSE:To utilize sunshine sufficiently even when the atmospheric temperature is low in winter, increase the amount of evaporation in a heat pump circuit and improve the heat collecting performance of the device by a method wherein an annexed heat exchanger, utilizing an annexed heat collector employing a loop heat pipe as a primary side heating source, is provided on the way of a returning pipe from a heat collector. CONSTITUTION:The annexed heat exchanger 8, utilizing the annexed heat collector 7 employing the loop heat pipe as the primary side heating source, is connected to the returning pipe from the heat collector 4 on the way thereof. In the heat collector 4, which is the evaporating unit of the heat pump circuit, it is hard to obtain sufficient amount of evaporation under low atmospheric temperature, frosting and no-wind condition, however, evaporative heat medium in the heat pump circuit is heated by the annexed heat exchanger 8 and is gasified perfectly when the sun shines and the temperature of the annexed heat collector 7 becomes high enough to operate the loop heat pipe. The heat medium in the annexed heat exchanger 8 is heated by the annexed heat collector 7, therefore, the evaporative heat medium is evaporated sufficiently and gasified as shown in the Mollier diagram by a broken line, thereafter, it enters into a compressor 1. |
