摘要： An air conditioning system for a vehicle has a first cycle including a compressor, a first condenser, a second condenser, a liquid tank, an expansion valve and an evaporator which are connected through pipes to form a first refrigerant circulation circuit through which a refrigerant flows from an outlet of the compressor to an inlet of the compressor while changing the phase. The first cycle causes the evaporator to act as a cooler when operated. The system further has a second cycle including the compressor, the second condenser, the liquid tank, the evaporator and the evaporator which are connected through pipes to form a second refrigerant circulation circuit through which the refrigerant flows from the outlet of the compressor to the inlet of the compressor while changing the phase. The second cycle causes the condenser to act as a heater and the evaporator to act as a cooler when operated. The first and second cycles are switched by switch means. The system further has an air duct case having an air flow passage in which the second condenser and the evaporator are installed. The air flow passage is connected at its downstream part to a passenger room of the vehicle. The air conditioning system further comprises heater means for heating a returning refrigerant which, under operation of the second cycle, flows in the pipe extending from an outlet of the evaporator to the inlet of the compressor.

摘要： Described is an apparatus for air conditioning a passenger compartment of an automotive vehicle which achieves a quick warming-up of the passenger compartment. In the air conditioning apparatus, in addition to a coolant of a vehicular engine which is utilized as a heat source of a heater core, a highly compressed refrigerant discharged from a compressor can be utilized as a heat source of a sub condenser which is disposed in an air passage of the air conditioning apparatus, during the inside air warming up in the passenger compartment. During the warming up operation, the refrigerant discharged from the compressor is circulated through a bypass line bypassing a condenser disposed at a front part of an engine compartment and through the sub condenser and an evaporator.

摘要： A heat pump type air conditioning system (A) for air-conditioning a passenger compartment of an automotive vehicle. The air conditioning system comprises first and second units (10, 20). The first unit includes a heater core (12) and a first evaporator (13) while the second unit includes a second condenser (22) and a second evaporator (23). A compressor (2) and a first condenser (3) are disposed outside the first and second units which constitute a refrigeration cycle including the first evaporator (13).

A third evaporator (30) is disposed outside the first and second units (10, 20). A flow control valve (31) is provided to control a flow amount of the engine coolant circulating through the third evaporator (30) in accordance with a thermal load condition of the vehicle under control of an opening degree of the flow control valve, during the heating operation of the air conditioning system. The flow control valve (31) is set to take its fully closed state to prevent the engine coolant from circulating through the third evaporator (30) when a discharge pressure of the compressor (2) rises to a level not lower a first set value which is lower than a standard value to stop an operation of the compressor, and to take its fully opened state to allow the engine coolant to circulate through the third evaporator (30) when the discharge pressure of the compressor (2) lowers to a level not higher than a second set value which is lower than the first set value.
