REFRIGERANT LEAKAGE DETECTION DEVICE, REFRIGERANT LEAKAGE DETECTION METHOD, AND REFRIGERANT LEAKAGE DETECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To perform detection of refrigerant leakage and identification of a refrigerant leakage place by using a simple structure.;SOLUTION: A refrigerant leakage detection device 100 detects leakage of a refrigerant 11 from a metallic refrigerant pipe 10 through which the refrigerant 11 flows, and detects the leakage of the refrigerant 11 on the basis of a capacitance between an approximately annular electrode band 22 wound around an outer periphery of a heat insulating material 12 covering an outer surface of the refrigerant pipe 10 and the refrigerant pipe 10.;SELECTED DRAWING: Figure 1;COPYRIGHT: (C)2019,JPO&INPIT
