In the era of rapid economic development in the 21st century, the industrial refrigeration industry has been recognized by more and more people. In recent years, more and more enterprises have used various types of industrial chiller, and chiller is in our life and production. The role is also increasingly important. However, many individuals or enterprises have very vague ideas about the structure type of the chiller when they choose and purchase the chiller. For example, people sometimes do not understand what is the difference between an air-cooled chiller and a water-cooled chiller? Today the supplier of China Industrial Water Chiller will work with you to understand the structure and difference of chiller.
In fact, industrial chiller can be divided into air-cooled type and water-cooled type according to its cooling type (condenser type). The air-cooled or water-cooled here refers to the method of discharging heat generated by the chiller during the refrigeration process; however, whether it is air-cooled or water-cooled chiller, the amount of cooling it generates is provided by chilled water. What kind of structure we can call it a chiller.
Structural features of air-cooled and water-cooled chiller:
The air-cooled chiller has its own cooling fan, and the condenser adopts fin type (copper tube is aluminum fin). The water-cooled chiller is equipped with a water condenser, which is generally a shell-and-tube condenser. Use cooling water towers and cooling water pumps.
Performance comparison of air-cooled and water-cooled chiller:
Advantages of air-cooled chiller: Air-cooled chiller includes Air Cooled Scroll Chiller Machine and air-cooled screw chiller, which is easy to install. The unit has been installed with a condensation fan, and no external cooling tower or cooling water pump is required. Save investment, no need to purchase cooling towers, pumps, water pipes, etc., reduce installation labor and installation cycle; it is more cost-effective for this small chiller. Easy to move: Compared with the water-cooled type, there is no cooling water pipe, which is more flexible and convenient to move; it is used in areas with insufficient water resources or poor water quality (high hardness or salty).

Disadvantages of air-cooled chiller: if the ambient temperature is high, the energy efficiency is only about 88% of that of water-cooled chiller; if the user already has a cooling water tower or pump, the investment cost of using air-cooled chiller for the first time Higher than water-cooled chiller; air-cooled chiller will emit hot air to the surrounding environment during operation, and there is noise from cooling fans.
Advantages of water-cooled chiller: Water-cooled chiller includes Water Cooled Scroll Chiller and water-cooled screw chiller. Compared with air-cooled chiller, the efficiency of water-cooled chiller is much higher, even in high ambient temperature The water cooler can also play a certain cooling effect on the equipment. The cooling performance is relatively stable, and it can also effectively play a certain throttling effect.
Disadvantages of water-cooled chiller: installation is cumbersome, and outdoor cooling water towers and water pumps must be used together during use, and because the unit works with water circulation to cool down the equipment, special water management is required.
Through the above overview, you should be able to better understand and understand the differences and functions of refrigeration equipment. Dongxing Refrigeration Co., Ltd. After years of technical accumulation, we can develop different types of equipment products according to different environmental conditions required by different types of factories Provide refrigeration equipment that meets the requirements for industrial development.
