Title:
WATER COOLING UNIT AND CONTROL METHOD
Document Type and Number:
WIPO Patent Application WO/2020/259131
Kind Code:
A1
Abstract:
Disclosed is a water cooling unit, comprising: a compressor, wherein the compressor comprises a primary compression cavity and a secondary compression cavity communicating with each other, and has a gas suction port, a low-pressure gas supply port, an intermediate-pressure gas supply port, and a gas discharging port; a condenser having a condensation inlet and a condensation outlet; a heat exchanger having a heat absorption channel and a heat discharging channel; an evaporator having an evaporation inlet and an evaporation outlet, wherein the evaporation outlet is connected to the gas suction port; and a gas-liquid separator having a liquid inlet, a first outlet, and a second outlet, wherein the first outlet is connected to the intermediate-pressure gas supply port, and the second outlet is connected to an inlet of the heat discharging channel. One path from an outlet of the heat discharging channel is connected to the evaporation inlet, and the other path is connected to an inlet of the heat absorption channel. In the water cooling unit of the invention, before entering the evaporator, a refrigerant passes through the heat discharging channel so as to discharge heat, thereby increasing the degree of supercooling of the refrigerant before the refrigerant enters the evaporator, increasing a cooling capacity per unit mass of the refrigerant, reducing flash gas in the refrigerant before same enters the evaporator, and decreasing a pressure and the temperature of the refrigerant.
