Refrigerant leakage detecting device, refrigerant leakage detecting system and refrigerant leakage detecting method

摘要

Problem to be solved: to suppress the occurrence of erroneous detection of refrigerant leakage by considering the change of capacitance due to temperature change.A refrigerant leakage detecting device is a capacitance measuring device for measuring an electrostatic capacity of a condenser comprising a refrigerant tube through which refrigerant flows and an electrode disposed on the outer periphery of the refrigerant tube, and a temperature measuring instrument for measuring the temperature which affects the measured value of the electrostatic capacity Based on the electrostatic capacity and the temperature, there is provided a control unit for detecting the leakage of the refrigerant from the refrigerant tube.The temperature measuring device measures the temperature in the installation environment where the refrigerant leakage detecting device is installed.Diagram
