Industrial cold water refrigeration system and working method

Abstract

The invention discloses an industrial cold water refrigeration system and a working method. The industrial cold water refrigeration system comprises a cold water refrigeration circulation loop, a coldwater circulation loop and a filter circulation loop, wherein the cold water refrigeration circulation loop comprises a vacuum pump, an evaporation tower, a cold water storage tank, a cold water pump, production cooling equipment, water pipes, a first valve and a second valve, and the water pipes, the first valve and the second valve are used for sequentially connecting the vacuum pump, the evaporation tower, the cold water storage tank, the cold water pump and the production cooling equipment. The cold water circulation loop includes the cold water pump, the production cooling equipment, thecold water storage tank, water pipes and valves, wherein the water pipes and the valves are used for sequentially connecting the cold water pump, the production cooling equipment and the cold water storage tank. The filter circulation loop includes the cold water storage tank, a circulation pump, filters, water pipes and a third valve, wherein the water pipes and the third valve are used for sequentially connecting the cold water storage tank, the circulation pump and the filters. The industrial cold water refrigeration system and the working method adopt water as a refrigerant and a refrigerating medium, and the water directly evaporates under a vacuum condition and turns into water vapor to take away heat, so that the purpose of refrigeration is achieved.

Description

technical field [0001] The invention relates to an industrial cold water refrigeration system and a working method. Background technique [0002] In industrial production, especially in chemical production, it is necessary to use a large amount of cold water at about 7°C for cooling, condensation, cooling, and cold preservation in production. In order to obtain cold water at about 7°C, a chiller is usually used. In the refrigeration industry, chillers are divided into air-cooled chillers and water-cooled chillers according to different cooling methods, and are further divided into screw chillers, scroll chillers and piston chillers according to different compressor types. chiller. Although the above forms are different, most of them use fluorocarbon or ammonia as the refrigerant. Through the compression method, the refrigerant becomes liquid under high pressure, and the heat is taken away by circulating water or wind; then through the method of throttling, the pressure dro...

AI Technical Summary

Problems solved by technology

During operation, once the pressure is over-pressured, it is easy to cause safety accidents such as explosion of the pressure vessel

[0005] 2. Some refrigerants are irritating, such as ammonia, etc.

Higher requirements for maintenance and construction

[0006] 3. In addition, most refrigerants, such as freon, ammonia, etc., once leaked, will pollute the atmosphere and the surrounding environment

[0007] 4. Since the refrigerant needs to be compressed and cooled after evaporation, the energy consumption is greatly increased
