Title:
REFRIGERANT LEAKAGE DETECTION DEVICE AND REFRIGERATION CYCLE DEVICE EQUIPPED WITH SAME
Document Type and Number:
WIPO Patent Application WO/2016/046961
Kind Code:
A1
Abstract:
Provided is a refrigerant leakage detection device that is not easily affected by changes due to aging, and that detects refrigerant leakage with good precision. This refrigerant leakage detection device is equipped with: an oxygen sensor (31) that outputs a signal with a voltage in accordance with the oxygen concentration inside a housing the interior of which accommodates a refrigerant pipe (23) in which a refrigerant gas is sealed; and detection units (32, 33) that, on the basis of the voltage for the signal output from the oxygen sensor (31), detect leakage of the refrigerant gas in the housing.
