Abstract

PURPOSE: To make a heating capacity high by a construction wherein a refrigerant piping connecting first and second indoor heat exchangers is provided for a refrigerant heater through which hot water heated by a waste heat of an engine is made to flow and the refrigerant flowing through the refrigerant piping is heated by the refrigerant heater at the time of heating.
CONSTITUTION: In a heating operation, an indoor space is heated by a heat radiated when a refrigerant is condensed and liquefied in first and second indoor heat exchangers 4a and 4b. The refrigerant condensed and liquefied again by the second indoor heat exchanger 4b is expanded under a reduced pressure to be an atomized refrigerant in a pressure-reducing device 7 and it is sent to an outdoor heat exchanger 8, wherein it is evaporated. The evaporated refrigerant passes again through a selector valve 3 and is subjected to gas-liquid separation in an accumulator 9, and a gas refrigerant led out therefrom returns to a compressor 2. Besides, cooling water of an engine 1 is heated to be hot water by a waste heat of a waste heat collecting device 10 and sent to a refrigerant heater 11, and after heating the refrigerant therein, the hot water passes through a thermo-valve 12. When the temperature of the hot water is a set temperature of the thermo-valve 12 or above, the hot water flows to a radiator 13, radiates the heat therein and then returns to the engine 1, while it returns to the engine 1 directly, not flowing to the radiator 13, when the temperature thereof is below the set temperature.
