Screw-type chiller is a kind of refrigeration equipment, which is used for cooling. It is usually used in cooling cooling of industrial equipment or air conditioning in the whole room (also known as central air-conditioning mainframe), because its cooling power is large, usually Only one or a few mainframes in a building can meet the needs of air conditioning. Industry is commonly used in pharmaceuticals, electronics, plastics, metallurgy, etc., to improve production efficiency!
Water-cooled screw chillers are widely used in industrial environment, factory equipment cooling and chemical, planting, reactor, fermenter, hospital, refrigeration and other industries of various scales of industrial refrigeration engineering, KDS screw freezer is the company's collection Years of experience in the design and production of chillers, combined with the development of zui new technology and painstaking research, design and development of chillers. This product is fast-changing development trend, adhering to the "efficient, reliable, energy-saving, environmentally friendly" design concept, to provide users with an excellent refrigeration equipment.

3. Working principle
The main components of the unit are: compressor, condenser, drying filter, gas-liquid separator, expansion valve, evaporator and control instrument and control components.
The working principle is as follows:
Refrigeration principle: When the refrigeration system is working, the high-temperature and high-pressure refrigerant gas discharged from the compressor enters the condenser and is condensed into a medium-temperature supercooled liquid. The low-temperature expansion valve is throttled and reduced to become a low-temperature low-pressure vapor-liquid two-phase mixture entering the evaporator. The heat of the brine flowing through the evaporator is evaporated and absorbed in the evaporator, so that the refrigerant flowing through the evaporator is cooled, and the vapor is vaporized and then sucked by the compressor to continuously circulate, thereby achieving the purpose of cooling.
