What is Pressure Regulator?
What is a Pressure Regulator in Refrigeration and HVAC Systems?
The Pressure Regulator’s main function is to control the balance of pressure within the refrigeration system piping to keep the refrigeration system operating within the designed pressure range.
It can be installed on the refrigeration system evaporator return line, condenser liquid line, evaporator air inlet, and compressor air return.
According to the installation position, we call the pressure regulator as evaporator pressure regulator, the condenser pressure regulator, the crankcase pressure regulator, and the hot gas bypass regulator.
