Modified Hose Flush Device and Method

摘要

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.

1. A refrigerant recovery system, comprising:
a refrigerant storage unit configured to store a refrigerant; a refrigerant charge path configured to convey the refrigerant to a refrigeration system to recharge the refrigeration system, the refrigerant charge path including:
a first service coupler disposed at a high side of the refrigeration charge path;a first service hose in fluid communication with the first service coupler;a second service coupler disposed at a low side of the refrigeration charge path; anda second service hose in fluid communication with the second service coupler; a flushing path configured to receive a flow of refrigerant for flushing the refrigeration charge path, the flushing path including:
a first flushing coupler in fluid communication with the first service hose; anda second flushing coupler in fluid communication with the second service hose; a processor configured to control the refrigerant recovery system to provide the flow of the refrigerant from the refrigerant storage unit, through the refrigerant charge path, and to the flushing path; and a memory to store diagnostic software and operating software to operate the refrigerant recovery system.
