Abstract
A refrigerant recovery system includes a refrigerant storage unit, a refrigerant charge path, a flushing path, a processor, and a memory. The refrigerant storage unit is configured to store a refrigerant. The refrigerant charge path is configured to convey the refrigerant to a refrigeration system to recharge the refrigeration system with the refrigerant. The refrigerant charge path includes a first and second service coupler and a first and second service hose. The service hoses are in fluid communication with the respective service couplers. The flushing path is configured to receive a flow of refrigerant for flushing the refrigeration charge path. The flushing path includes a first and second flushing coupler. The processor is configured to control the refrigerant recovery system to provide a flow of the refrigerant from the storage unit, through the refrigerant charge path, and to the flushing path.
