Title:
車両空調装置用ヒートポンプシステム
Document Type and Number:
Japanese Patent JP7117945
Kind Code:
B2
Abstract:
A vehicle air-conditioning apparatus heat pump system configured so that an excessive increase in the temperature (superheat degree) of refrigerant discharged from a compressor can be prevented in air-heating operation. The heat pump system (HP) includes a compressor (C) and an indoor heat exchanger (HXC2) on a refrigerant circuit (RC). A first branched flow path (BC1) on which a first expansion mechanism (EX1) with an adjustable opening degree and a first heat absorption heat exchanger (HXA1) are arranged in series and a second branched flow path (BC2) on which a second expansion mechanism (EX2) with an adjustable opening degree and a second heat absorption heat exchanger (HXA2) are arranged in series, where the first branched flow path (BC1) and the second branched flow path (BC2) are arranged in parallel on the refrigerant circuit extending from the indoor heat exchanger to the compressor.
