Screw Chiller Works
- Dec 21, 2017 -

Screw chiller is a professional refrigeration equipment, widely used in various industries, injection molding industry, roller industry, extrusion and reactor, is a certain time and space is an object or liquid cooling, the temperature dropped to production The temperature required for the process, and to maintain the temperature stability.

       Screw chillers mainly through the refrigerant a series of thermal changes, and the object to be cooled heat exchange, take away the extra heat to produce chilled water, cooling equipment or products.

      According to the requirements of the production process, the screw chiller is divided into ordinary refrigeration, deep refrigeration, low temperature refrigeration and ultra-low temperature refrigeration. Commonly used cooling methods are vapor compression, absorption, steam, adsorption and other methods,

      The following is a brief description of the commonly used vapor compression refrigeration on the market:

The refrigeration system consists of compressor, condenser, expansion valve and evaporator. The refrigerant exchanges heat with the object to be cooled in the evaporator, absorbs heat, generates low-pressure steam, and then is sucked and exhausted by the compressor at high temperature and high pressure. The high-temperature and high-pressure gas refrigerant discharged from the compressor is condensed in the condenser by a normal-temperature cooling medium ) Cooling, high temperature liquid at room temperature condensation. High-pressure liquid flow through the expansion valve throttling, the formation of low-pressure and low-temperature steam, low pressure liquid into the evaporator, evaporator and then vaporization refrigeration, the cycle, to complete the entire process of refrigeration.
