Air conditioning system for internal combustion engine of hybrid vehicle, has compressors arranged parallel to each other, where compressor of engine and compressor of electromotor are driven, and common capacitor attached to compressors

摘要

The system (4) has two compressors (3, 6) arranged in parallel, where the compressor of a combustion engine (2) and the compressor of an electromotor (7) are driven. A common capacitor (8) is attached to the compressors. A crankshaft of the combustion engine is drivingly connected by a belt drive (5). The compressor of the electromotor is connected with a high voltage battery (9). A three-way valve (10) controls a division of coolant flow on the compressors. Two vaporizers (11, 12) are parallelly switched, and thermostatic expansions (13, 13') are arranged between the vaporizers.
