Title:
REFRIGERANT LEAKAGE NOTIFICATION DEVICE AND REFRIGERATION CYCLE SYSTEM PROVIDED WITH REFRIGERANT LEAKAGE NOTIFICATION DEVICE
Document Type and Number:
WIPO Patent Application WO/2021/010233
Kind Code:
A1
Abstract:
The present invention provides a highly reliable refrigerant leakage notification device and a refrigeration cycle system provided therewith. A refrigerant leakage notification device (80) is provided with a refrigerant sensor (34), a determination unit (44c), a notification unit (70), and an output unit (44e) different from the refrigerant sensor. The refrigerant sensor detects a refrigerant and outputs a detection signal that corresponds to a detection result. The determination unit receives the detection signal outputted by the refrigerant sensor and determines leakage of the refrigerant on the basis of the received detection signal. The notification unit makes notification of leakage of the refrigerant by at least one of sound and light when the determination unit determines that the refrigerant is leaking. The output unit outputs a test signal (TS) to the determination unit. The test signal is such that the determination unit determines that the refrigerant is leaking upon receiving the test signal.
