Abstract
It is possible to detect refrigerant leakage while pinpointing the location where refrigerant leakage is occurring in a refrigerant circuit of a refrigeration system. A fluid sensor (8) is a fluid sensor for detecting refrigerant leakage from a refrigerant circuit (10), wherein the fluid sensor includes a sensor main body (8a) having two electrodes (81, 82) spaced apart, and the fluid sensor (8) is configured such that the fluid sensor (8) is capable of being connected to an impedance measurement device (9) for measuring impedance between the two electrodes (81, 82).
