Abstract
In refrigeration system, a first solenoid operated valve in parallel disposition with an inlet pressure regulator for refrigerant to a receiver. The refrigeration system also includes a second solenoid operated valve disposed in a receiver bypass line. The first solenoid valve is a normally open valve and the second, bypass solenoid valve is a normally closed valve. A sensor is disposed on the outlet of the condenser of the refrigerant system for determining the condition of refrigerant exiting the condenser. A controller then operates the first solenoid valve and the second solenoid valve to direct flow to the receiver or to bypass the receiver if the refrigerant is subcooled.
