  • Patent number: 7958744
    Abstract: An apparatus for safely and efficiently purging refrigerant lines interconnected with residential and light commercial air conditioning systems. Enhanced safety is achieved by enabling the operator to conduct purge operations away from enclosed areas such as attics and crawlspaces. Efficient use of solvent is achieved by simultaneously connecting a refrigerant line connector to the evaporator end of both suction line and liquid line and discharging solvent and compressed gas through a solvent bridge connected to the compressor end of the liquid line. Thorough contaminant removal enables retrofitting air conditioning systems for use with newer, legally required refrigerants.
