Title:
COOLING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/005701
Kind Code:
A1
Abstract:
The present invention provides a cooling system capable of comprehensively improving the efficiency of an evaporation/condensation phase-change cycle of a refrigerant. The cooling system of the present invention is characterized by having a local cooler (1) positioned near a heat source and directly receiving heat from said heat source to evaporate a liquid-phase refrigerant, a turbo compressor (2) for compressing a gas-phase refrigerant produced in said local cooler (1), an outdoor unit (3) for condensing the gas-phase refrigerant supplied from said turbo compressor (2) by performing heat dissipation on the gas-phase refrigerant, and an expansion valve (4) for depressurizing refrigerant supplied from said outdoor unit (3) and sending the refrigerant to the local cooler (1), the refrigerant being a low-pressure refrigerant having a condensation pressure that is lower than a prescribed value.
