Title:
COLD HEAT SOURCE UNIT, REFRIGERATION CYCLE DEVICE, AND REFRIGERATING MACHINE
Document Type and Number:
WIPO Patent Application WO/2021/240645
Kind Code:
A1
Abstract:
A cold heat source unit (2) comprises: a first flow path (F1) that is configured so as to receive a refrigerant from an evaporator (60) and send the refrigerant toward a first expansion device (50) through a compressor (10) and a condenser (20); a second flow path (F2) for sending the refrigerant that has passed through the condenser (20) to the compressor (10), without passing through the first expansion device (50) and the evaporator (60); a second expansion device (92) that is provided in the second flow path (F2); and a plurality of temperature sensors (121-123) that are arranged in the second flow path (F2). The control device (100) is configured so as to control the refrigeration cycle device (1) so that the temperatures detected by the plurality of temperature sensors are equal, calculate an average value of the temperatures detected by the plurality of temperature sensors, and perform a correction of each of the plurality of temperature sensors on the basis of the difference between the average value and the temperature detected by each of the plurality of temperature sensors.
