Heating-, ventilation-, and air-conditioning apparatus for use in passenger compartment of motor car, has air-conditioning loop with compressor, which includes cooling system, and heat exchanger arranged downstream of compressor

摘要

The apparatus (1) has an air-conditioning loop (2) comprising a compressor (3), which includes a cooling system (7) through which coolant circulates in a cooling loop (8). The cooling loop is thermally connected with the air-conditioning loop through a heat exchanger (10). The heat exchanger is arranged downstream of the compressor. The cooling loop includes another heat exchanger (11) that is arranged downstream of the former heat exchanger. The cooling loop is provided with a distribution unit (14) adapted to feed the latter heat exchanger and a third heat exchanger (12). The second heat exchanger is designed as an internal heat exchanger, a condenser (4) and an evaporator (5). The third heat exchanger is designed as an external heat exchanger and a reversible heat exchanger (6).
