Title:
OPERATION CONTROL METHOD AND COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2022/138520
Kind Code:
A1
Abstract:
The present invention controls liquid-refrigerant temperature, whereby stabilized cooling properties can be demonstrated. In this method of controlling the operation of a refrigerating system 1 having a chiller 23 that chills saltwater B by heat exchange with a liquid refrigerant Rℓ, the liquid refrigerant Rℓ is supplied with a gas refrigerant Rg in a high-pressure gaseous state to control the temperature of the liquid refrigerant Rℓ inside the chiller 23. Furthermore, a refrigerant R is compressed with a compressor 21 to generate the gas refrigerant Rg, and the gas refrigerant Rg is condensed with a condenser 22 to generate the liquid refrigerant Rℓ. Furthermore, on the basis of the pressure of the liquid refrigerant Rℓ inside the chiller 23, the quantity of the gas refrigerant Rg supplied to the liquid refrigerant Rℓ is feedback-controlled.
