Coolant Circuit, in Particular a Heat Pump Circuit

摘要

A heat pump circuit has the following components when seen in the flow direction: a compressor; a condenser or gas cooler; a first coolant/air heat exchanger as a sub-cooler, via which the coolant dispenses heat; a first expansion element; a first coolant/air heat exchanger, via which the coolant absorbs heat from the ambient air; a second expansion element; and a third coolant/air heat exchanger, via which the coolant absorbs heat from the ambient air. The arrangement of the heat exchanger is in front of the drive engine relative to the travel direction. The danger of the ambient heat exchanger freezing is minimized. With this arrangement

1. A refrigerant circuit which, when viewed in a flow direction of refrigerant, comprises:
a compressor; a condenser or gas cooler; a first refrigerant/air heat exchanger via which the refrigerant discharges heat; a first expansion member; a first refrigerant/air heat exchanger via which the refrigerant absorbs heat from the ambient air; a second expansion member; and a third refrigerant/air heat exchanger via which the refrigerant absorbs heat from the ambient air.
