摘要： A refrigerant handling system includes a cabinet having two service ports and two sample ports and housing recycling/recharging apparatus coupled to the service ports and a refrigerant identifier coupled to one of the sample ports and coupled through solenoid-actuated valves to the recharging/recycling apparatus. Two coupling assemblies are provided for coupling the cabinet to the high-pressure and low-pressure sides, respectively, of an automotive air conditioner, each coupling assembly including a service hose with end couplers for respectively coupling to the air conditioner and one of the service ports and connected through solenoid-actuated valves disposed within a housing closely adjacent to the air conditioner coupler. Each coupling assembly also has a sample hose communicating with the service hose within the housing between the air conditioner coupler and the valves and having a distal end with a coupler for connection to one of the sample ports, and electrical conductors for control of the valves.
