Abstract

A refrigeration system for a vehicle including a refrigerant circuit having a double-flow heat exchanger, it being possible to operate the heat exchanger as a refrigerant condenser/gas cooler for an AC mode or as an air heat pump evaporator for a heat pump mode. The first flow of the heat exchanger has a first refrigerant connection and the second flow of the heat exchanger has a second refrigerant connection. For double flow through the heat exchanger in AC mode the first refrigerant connection is a refrigerant inlet and the second refrigerant connection is a refrigerant outlet. For single flow through the heat exchanger in heat pump mode the second refrigerant connection is a refrigerant inlet.
