REFRIGERATION CYCLE DEVICE, REMOTE MONITORING SYSTEM, REMOTE MONITORING DEVICE, AND ABNORMALITY DETERMINATION METHOD

摘要

This refrigeration cycle device is equipped with: a refrigeration circuit which includes a compressor, a condenser, a throttle device, and an evaporator; a control unit which controls the refrigeration circuit; and an abnormality determination unit which determines the presence or absence of abnormalities in the refrigeration circuit. The control unit drives the compressor, and performs special operation for stopping the compressor if a predetermined time has elapsed or if the pressure of a refrigerant on the intake side of the compressor decreases to a predetermined value. The abnormality determination unit determines the presence or absence of abnormalities in the refrigeration circuit after the special operation.
