Title:
HEAT SOURCE UNIT AND REFRIGERATION DEVICE
Document Type and Number:
Japanese Patent JP2023092357
Kind Code:
A
Abstract:
To solve a problem in which propriety of refrigerant amount filled in a refrigerant circuit and detection accuracy of presence/absence of refrigerant leakage are insufficient.SOLUTION: A heat source unit (2) is connected to a utilization unit (5) to constitute a refrigerant circuit performing a refrigeration cycle. The heat source unit (2) includes a compressor (21), a first heat exchanger (24), a supercooling heat exchanger (29) and a first temperature sensor (46). The compressor (21) compresses a refrigerant. The first heat exchanger (24) is used as a condenser for the refrigerant. The supercooling heat exchanger (29) cools the refrigerant discharged from the first heat exchanger (24) during an operation in which the first heat exchanger (24) is used as the condenser. The first temperature sensor (46) is disposed between an inlet and an outlet of the supercooling heat exchanger (29), and measures a temperature of the refrigerant. By using the temperature measured by the first temperature sensor (46), refrigerant amount in the refrigerant circuit 10 is detected.SELECTED DRAWING: Figure 1
