ABSTRACT:
The present invention provides a refrigerant conservation system and method for preventing the release of refrigerant to the atmosphere during high pressure system failure. Refrigerant is delivered from the refrigerant loop of the refrigerant system to an evacuated sealed receiver. The receiver tank may be retrofitted to the existing high pressure safety relief valve of a mechanical refrigeration system. When the pressure in the receiver tank exceeds a predetermined value, operating current is denied to the compressor to prevent its operation and to contain refrigerant within a closed system which would otherwise be discharged into the atmosphere.
