Title:
DIAGNOSTIC DEVICE AND REFRIGERATION CYCLE DEVICE HAVING SAME
Document Type and Number:
WIPO Patent Application WO/2023/145016
Kind Code:
A1
Abstract:
This diagnostic device comprises: a refrigerant flow rate sensor that detects the flow rate of refrigerant circulating in a refrigerant circuit; a receiver that acquires information related to the intake temperature, which is the temperature of the refrigerant taken into a compressor, the discharge temperature, which is the temperature of the refrigerant discharged from the compressor, the supercooled temperature, which is the temperature of the refrigerant flowing out from a condenser, the condensation pressure or condensation temperature, and the evaporation pressure or evaporation temperature; a storage device that pre-stores capacity information indicating the air-conditioning capacity of a refrigeration cycle device in a normal state; a controller that determines whether the refrigeration cycle device is normal or not on the basis of the flow rate detected by the refrigerant flow rate sensor, the information acquired by the receiver, and the capacity information stored in the storage device; and an output device that outputs the determination result of the controller.
