ABSTRACT:
The present invention consists of a refrigeration unit with an adjusting valve that functions to control the flow of refrigerant and which is installed between the condenser and the evaporator. The adjusting valve is modulated by a controller that adjusts the refrigerant flow from the condenser to the evaporator, depending upon the outflow refrigerant vapor pressure coming from the compressor, condenser, or evaporator. Thus, substantial energy losses are avoided.
