Patent ID: 7958744

Claim:
A refrigerant purge apparatus detachably interconnected with refrigeration piping of an air conditioning system, wherein liquified refrigerant is cyclically transported through a liquid line from a compressor to a remotely located evaporator in which said liquified refrigerant expands to a substantially gaseous state thereupon being transported by pressure differential through a suction line back to said compressor in which now gaseous refrigerant is re-liquified completing a single refrigeration cycle, with said refrigeration piping first being disconnected from said evaporator and said compressor, said refrigerant purge apparatus comprising: a refrigeration line connector joining an evaporator end of said liquid line proximal to said evaporator to an evaporator end of said suction line proximal to said evaporator, thereby bypassing said evaporator; and a solvent bridge joining each of a compressor end of said liquid line proximal to said compressor, a cannister containing solvent, and a tank containing pressurized gas, thereby enabling simultaneous purging of both said liquid line and said suction line when said solvent and said pressurized gas are released into said liquid line.
