Defrosting valve for refrigeration system is normally closed, opens if predefined opening pressure is exceeded, is combined with regulating valve in common valve housing with two inputs and output

摘要

The defrosting valve (70) is arranged in a bypass line between the output of a compressor (51) and the input of an evaporator (53) in a refrigeration system with a compressor, heat exchanger (52), regulating valve (60) and evaporator. The defrosting valve is normally closed and opens if a predefined opening pressure is exceeded. The defrosting valve is combined with the regulating valve in a common valve housing with two inputs and an output.
