|1. (WO2017057377) REFRIGERANT LEAKAGE SPOT SPECIFYING METHOD|
|Applicants:||DAIKIN INDUSTRIES, LTD.
|Title:||REFRIGERANT LEAKAGE SPOT SPECIFYING METHOD|
Provided is a refrigerant leakage spot specifying method that is capable of, while suppressing an increase in cost, specifying a refrigerant leakage spot when leakage of a refrigerant occurs. The refrigerant leakage spot specifying method applied in a refrigeration apparatus (100) is a method for specifying a refrigerant leakage spot when leakage of a refrigerant occurs in a refrigerant circuit (RC) including: a compressor (11); a liquid-side closing valve (17) that can form a closed state to block the flow of the refrigerant; a gas-side closing valve (18); and a use-side expansion valve (32). The method includes: a step for dividing the refrigerant circuit (RC) into a plurality of refrigerant flow paths by setting each of the valves to a closed state when the compressor (11) is stopped; and a step for determining whether or not there is a leakage of the refrigerant in any of the refrigerant flow paths by detecting a change in the state of the refrigerant in each of the refrigerant flow paths after the first step.
