Performance comparison of air - cooled and water - cooled chiller

In recent years, more and more enterprises are using all kinds of industrial water chillers, and the role of water chillers in our life and production is more and more important. However, many individuals or enterprises in the selection and purchase of water chiller structure type concept of water chiller is still very vague, for example: people sometimes do not understand the difference between air cooled chiller and water cooled chiller? Today, let's learn about the structure and difference of chillers.

In fact, according to its cooling type (condenser type), industrial chiller can be divided into two categories: air-cooled and water-cooled. Here refers to the air cooling or water cooling, refers to the chiller in the refrigeration process of the heat discharge; But whether it is air cooling or water cooler, the cold capacity generated by it is provided by the form of frozen water, so no matter what kind of structure we can call chiller.

Structural characteristics of air cooled and water cooled chiller

Air cooled chiller has cooling fan, condenser adopts finned type (copper tube is aluminum fin)

Water cooled chiller is equipped with water condenser, generally shell and tube condenser, generally need to be equipped with cooling tower and cooling water pump to use.

Comparison of the performance of air cooled and water cooled chiller:

Advantages of air cooled chiller: easy to install, the unit has been installed condensation fan, no need to external cooling tower, cooling water pump. Save investment, no need to purchase cooling tower, water pump, water pipe and other costs, reduce installation labor and installation cycle; For some small chiller more cost-effective, easy to move: compared with water cooling, no cooling water pipe, more flexible and convenient movement; For the lack of water resources, or water quality is not good (high hardness or salt) use.

Disadvantages of air cooled chiller: such as in the case of high ambient temperature, energy efficiency is only about 88% of water cooled chiller; If the user has cooling water tower or water pump, the investment cost of the first use of air cooled chiller is higher than that of water cooled chiller; The air cooled chiller will discharge hot air to the surrounding environment and make noise from the cooling fan.

Advantages of water-cooled chiller: compared with air-cooled chiller, the efficiency of water cooler is much higher. Even if the ambient temperature is higher, the water cooler can play a certain cooling effect on the equipment. The cooling performance is stable, but also can effectively play a certain throttling role.

Disadvantages of water-cooled cooling chiller: installation is more complicated, use needs to be equipped with outdoor cooling water tower and water pump together, and because the unit is working in water circulation to cool the equipment, so the need to do the water management, later maintenance and maintenance costs are high.
