<p>PURPOSE:To prevent decrease of the running distance of an electric automobile and quicken build-up of heating in the vehicle room. CONSTITUTION:Hot water in a heat insulating tank 54 heated by means of an electric heater 43 during charging of a battery 4 is supplied into the water refrigerant heat exchanger 28 of a heat pump so as to heat refrigerant flowing in the water refrigerant heat exchanger 28, and hence build-up of heating in a vehicle room is quickened. At taking a riding on the automobile, by heating hot water in a hot water circulating passage 42 by waste heat of a running motor 6 and an inverter 5 and circulating the hot water in the water refrigerant heat exchanger 28 so as to improve the result factor of the heat pump and perform heating in the vehicle room, power of a refrigerant compressor is saved, and hence exhaustion of the battery 4 is restrained and decrease of the running distance of an electric automobile is prevented.</p> |
