Title:

REFRIGERATION/AIR-CONDITIONING DEVICE

Document Type and Number:

WIPO Patent Application WO/2021/186549

Kind Code:

A1

Abstract:

A refrigeration/air-conditioning device (1) comprises an outdoor unit (3) and an indoor unit (5). The outdoor unit (3) houses a compressor (7), a heat exchanger (10), and a liquid reservoir (11). The indoor unit (5) houses an expansion valve (15) and a heat exchanger (14). As a refrigeration cycle, the compressor (7), the heat exchanger (10), the liquid reservoir (11), the expansion valve (15) and the heat exchanger (14) are connected in this order by a refrigerant pipe (31). A fluorescent agent for detecting leakage of a refrigerant from the refrigerant pipe (31) and the like is added to refrigeration oil that circulates together with the refrigerant in the refrigerant pipe (31). A window (17) for checking the condition in the refrigeration cycle is formed in the refrigeration cycle.
