Abstract

The invention discloses an evaporation condensation high-efficiency screw water chilling unit with a deep supercooling device and belongs to refrigeration machinery. The water chilling unit overcomes the shortcomings of poor operation efficiency of the unit and the like in the prior art of improving supercooling degree. The water chilling unit comprises a compressor, an evaporation condenser, a liquid storage, a throttling device and an evaporator. The outlet side of the evaporator is connected with the inlet side of the compressor. The water chilling unit is characterized in that a deep supercooling device is connected in a circulation refrigerant loop between the liquid storage and the throttling device, a water collecting tank is arranged at the bottom of the evaporation condenser, and a cooling water pipe conducting heat exchange with the circulation refrigerant is introduced in the deep supercooling device and communicated with the evaporation condenser. The liquid refrigerant and normal temperature tap water conduct heat exchange in the deep supercooling device to enable high pressure liquid refrigerant to release heat to the cooling water, the temperature of the refrigerant entering the throttling device is greatly reduced under the premise that the heat exchange effect of the condenser is not affected, and deep supercooling is achieved.

Description

technical field [0001] The invention belongs to the technical field of refrigeration machinery, in particular to an evaporative condensation high-efficiency screw chiller with a deep supercooling device. Background technique [0002] With the acceleration of urbanization and the improvement of residents' living standards, the energy consumption of air conditioning systems accounts for an increasing proportion of my country's total energy consumption. Improving the energy efficiency level of air conditioning systems is of great significance for energy saving, emission reduction and sustainable development. The refrigerant liquid before subcooling and throttling can increase the cooling capacity per unit mass of refrigerant and reduce the flash gas generated after throttling. The refrigerant entering the evaporator is evenly distributed, improving the refrigeration coefficient, and sufficient over Coldness is a necessary condition for the stable operation of the refrigeration...
