What is a water-cooled screw chiller
Chiller is a common refrigeration equipment, which is divided into two types: screw type and scroll type; these two refrigeration forms are divided into water-cooled screw type chiller, air-cooled screw type chiller, water-cooled scroll type chiller There are four types of chillers, air-cooled scroll chillers. The water-cooled screw chiller is one of the industrial chillers, which are widely used in industrial and commercial fields, such as factories, shopping malls, schools, office buildings, etc. Compared with other types of chillers, the water-cooled screw chiller has Efficient, stable, and reliable, so it has attracted much attention in many application scenarios; the working principle of water-cooled screw chillers has always been one of the issues that many people are concerned about. This article will introduce it.
The important components of the water-cooled screw chiller are as follows:
Expansion Valve
PLC Control System
Condenser+Evaporator+Screw Compressors
Water-cooled screw chiller Working principle：
1：First, the refrigerant enters the system from the evaporator and is in a low-pressure state. In the evaporator, the refrigerant absorbs external heat and evaporates into gas. This process reduces the temperature of the evaporator;
2：The evaporated refrigerant enters the screw compressor in the form of gas, and the main screw and auxiliary screw in the screw compressor rotate to compress the gas gradually. Under the action of the screw compressor, the temperature and pressure of the refrigerant gradually increase, and finally Become a high-temperature and high-pressure gas;
3：The high-temperature and high-pressure gas enters the condenser, where the refrigerant exchanges heat with the cooling water, releases heat and cools into a liquid, the temperature of the condensed refrigerant drops, and the pressure remains at a high level;
4：The cooled liquid refrigerant passes through the expansion valve, the pressure is reduced, and the expansion valve controls the flow of the refrigerant so that it flows to the evaporator; the depressurized refrigerant re-enters the evaporator, continues to absorb external heat and evaporates into gas. The entire refrigeration cycle is repeated continuously to maintain a constant refrigeration effect;
The above is the working principle process of the water-cooled screw chiller
Conclusion
Example: The water-cooled screw chiller mainly realizes the cooling effect through the screw compressor and the refrigeration cycle principle. Its working principle is simple and efficient, and can provide stable and reliable cooling effect. With the continuous development of technology, the water-cooled screw chiller Significant progress has also been made in energy efficiency and environmental protection, and it has become an indispensable and important equipment in modern buildings and industrial facilities; if you plan to purchase this equipment now, please contact Feizhong to purchase Chinese water-cooled screw chillers, customized Exclusively your chiller refrigeration system.
