AIR-CONDITIONING SYSTEM REFRIGERANT RECOVERY AND FILLING SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2020/223948
Kind Code:
A1
Abstract:
Disclosed are an air-conditioning system refrigerant recovery and filling system (200) and method. The refrigerant recovery and filling system (200) comprises a first compressor (201), a refrigerant temporary storage tank and a refrigerant storage tank (204), wherein an inlet of the first compressor (201) communicates with an air-conditioning system (100) and is configured to compress a refrigerant in the air-conditioning system (100) into a high-temperature and high-pressure gas refrigerant; an inlet of the refrigerant temporary storage tank communicates with an outlet of the first compressor (201), a refrigerant outlet of the refrigerant temporary storage tank respectively communicates with the air-conditioning system (100) and a refrigerant inlet of the refrigerant storage tank (204), and the refrigerant temporary storage tank is configured to fill the air-conditioning system (100) with at least some of the high-temperature and high-pressure gas refrigerant; and the refrigerant inlet of the refrigerant storage tank (204) communicates with the refrigerant outlet of the refrigerant temporary storage tank, and the refrigerant storage tank (204) is configured to store the refrigerant compressed by the first compressor (201) and then flowing out of the refrigerant outlet of the refrigerant temporary storage tank. The air-conditioning system refrigerant recovery and filling system (200) and method improve the recovery speed and recovery efficiency of a refrigerant.
