Abstract
An air conditioning system for a motor vehicle powered by an internal combustion engine has a first system for carrying out a first cycle, which includes a compressor driven by the engine, a main condenser, a first sub-condenser 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 same while changing its phase, the first cycle causing the first sub-condenser as a heater and the evaporator as a cooler when operated. The air conditioning system has further a second system for carrying out a second cycle, which includes the compressor and a second sub-condenser 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 same while changing its phase, the second cycle causing the second sub-condenser as a heater when operated. First and second independent air flow passages are defined. The first passage has the heater core, the first sub-condenser and the evaporator installed therein, and the second passage has the second sub-condenser installe…
