Cooling-circuit for air conditioning system of motor vehicle, has compressor for compressing coolant, and accumulator arranged between evaporator and heat exchanger, where average density of coolant has specified kilogram per cubic meter

摘要

The circuit has a compressor provided for compressing gas-formed coolant, and a gas cooler (3) for cooling the coolant that heated by the compression. An expansion unit is formed in the proximity of a high pressure side output of an inner heat exchanger (4). An accumulator (7) is arranged between an evaporator (6) and the heat exchanger, where the average density of the coolant has a maximum of 260 kilogram per cubic meter. An independent claim is also included for a method for filling a cooling-circuit.
