Air conditioning system for cooling passenger compartment, has heating device e.g. electrical heating device, arranged between condenser and compressor in feed line of compressor for preheating refrigerant

摘要

The system (1) has a refrigerant circuit (2) for a refrigerant. The refrigerant circuit has a refrigerant compressor (3), an expansion valve (4) associated with an evaporator (5) for cooling an interior of a motor vehicle, and a condenser (6). A heating device (7) e.g. electrical heating device, is arranged between the condenser and the compressor in a feed line of the compressor for preheating the refrigerant. The electrical heating device heats the refrigerant by an electrical energy.
