Title:
COLD HEAT SOURCE UNIT AND REFRIGERATION CYCLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2022/013975
Kind Code:
A1
Abstract:
This cold heat source unit (2) is configured so as to be connected to a load device (3) that includes a first expansion device (50) and an evaporator (60). The cold heat source unit (2) comprises: a first flow path (F1) that is connected to the load device (3), thereby forming a refrigerant flow path in which a refrigerant circulates; a compressor (10), and condenser (20), and a refrigerant cooling device (30) that are positioned in sequence in the first flow path (F1); a pressure sensor (112) and a temperature sensor (121) that respectively detect the pressure and the temperature of the refrigerant sent from the refrigerant cooling device (30) to the first expansion device (50); and a control device (100). The control device (100) modifies the cooling performance of the refrigerant cooling device (30) on the basis of the outputs from the pressure sensor (112) and the temperature sensor (121).
