ABSTRACT:
According to the present invention, in a brine type air-conditioning apparatus in which brine circulates into an inside cooler to cool a passenger compartment, there are provided a refrigeration cycle using flammable gas as refrigerant, a brine circuit in which the brine circulates, a hot water circuit in which hot water heated by an engine circulates, a front air-conditioning unit for performing an air-conditioning of a front portion in the passenger compartment, a rear air-conditioning unit for performing an air-conditioning of a rear portion in the passenger compartment. In the front air-conditioning unit, there are provided a cooler for cooling conditioned air by using the brine, a heater for heating conditioned air by using the hot water, a blower. In the rear air-conditioning unit, there are provided an air-conditioning heat exchanger for cooling conditioned air by using the brine and for heating conditioned air by using the hot water, and a blower. For adjusting a temperature of the low-temperature side, the heating amount by the heater is set to zero, and a temperature of the brine is variably controlled by varying a capacity of the refrigeration cycle.
