ABSTRACT:
Apparatus and method for preventing leakage of refrigerant fluid from a closed air conditioning or refrigeration system having a sealed compressor, an evaporator, a receiver and a condenser, the apparatus including a solenoid-actuated valve for segmenting the refrigerant within the closed system away from the most leak-prone area of the system. A pump is provided for the periodic spraying of lubrication fluid onto a condenser seal to prevent drying of the seal. A containment compartment or trap is provided for catching refrigerant diverted by a diversion valve, the containment compartment having an improved high pressure relief valve, with an indicator for indicating the occurrence of a high pressure exhaust of refrigerant into the atmosphere.
