East Star industrial chillers, in accordance with the cooling mode is divided into wind cooled and water cooled chillers two; according to the structure is divided into seal chiller and open type chiller; scroll chiller by compressor type, piston type chiller, screw chiller; according to temperature into the high temperature water cooling machine (standard cold water machine, cold water machine). So, what is the difference between the screw chiller and the open water chiller?
     Screw type cold water machine, because of its use of screw compressor and the name, there are air-cooled and water-cooled screw chiller. The unit power is relatively large, so the smallest screw chiller model is 30hp. The utility model has the advantages of simple structure, and is composed of a compressor, an evaporator, a condenser, an electric control system and a refrigeration fitting.
    Open water chillers only water-cooled, so some users also known as water cooling open water, it uses a scroll or piston compressor, more models, small to 3P, large 60p and other models to choose. Open type cold water machine, as the name suggests, it is open, also consists of compressor, evaporator, condenser, electric control system, refrigeration accessories, mainly used in plastics, electronics, pharmaceutical, food preservation and other industries.
     Therefore, according to the structure of screw type chiller and open water chillers, both belong to the open type cold water machine series; according to the configuration, using two different compressor types; according to the cooling mode, screw chiller can make air cooled screw chiller, water cooled screw chiller, open type cold water machine do water-cooled.
     How to determine the type of chiller required by the plant? 1, to see what equipment is used, is the need for air-cooled or water-cooled chiller. 2, the demand for the power of the chiller, if the power is not large, there is no need to select the screw chiller. 3, open type cold water machine does not have the outer box, if the factory on the appearance of the cold water machine is higher, it is suggested that the use of sealed cold water (box type cold water machine).
