TEMPERATURE CONTROL SYSTEM WITH REFRIGERANT RECOVERY ARRANGEMENT

摘要

A temperature control system includes a compressor, a condenser, an evaporator, a receiver, and an accumulator. A valve is positioned between the evaporator and the receiver. An evacuation line has a first end in fluid communication with heat transfer fluid between the valve and the receiver, and a second end in fluid communication with the accumulator. The evacuation line provides for flow of the heat transfer fluid from both of the first heat exchanger and the receiver to the accumulator during an evacuation mode of operation of the temperature control system. The valve can take the form of a check valve or an expansion valve without a bleed port.
