Refrigeration system for a vehicle with a refrigerant circuit having a double-flow heat exchanger and heat exchanger and method for operating the refrigeration system

摘要

The invention relates to a refrigeration system (10) for a vehicle with a refrigerant circuit (1) having a double flow heat exchanger (2), the double flow heat exchanger (2) being operable as a refrigerant condenser or gas cooler for a refrigeration system operation or as an air heat pump evaporator for a heat pump operation is. According to the invention, the first flood (2.1) of the heat exchanger (2) has a first refrigerant connection (2.10) and the second flood (2.2) of the heat exchanger (2) has a second refrigerant connection (2.20), whereby for the double-flow flow through the heat exchanger Refrigeration system operation, the first refrigerant connection (2.10) is a refrigerant inlet (EAC) and the second refrigerant connection (2.20) is a refrigerant outlet (AAC), the heat exchanger (2) for the exclusive flow through the second flood (2.2) in heat pump mode, one with the second Flood (2.2) connected third refrigerant connection (2.30) as the refrigerant outlet (AWP) of the second flood (2.2), and the third refrigerant connection (2.30) with a valve member (2.5) for controlling the refrigerant emerging from the heat exchanger (2) is fluid-connected. The invention further relates to a heat exchanger for the refrigeration system according to the invention and a method for operating the same.
