Chiller units are refrigerant systems that aid in cooling residential/commercial spaces, machines, industrial operations, and industrial chemicals. These units are energy efficient, cost-efficient, and time-efficient. Without these systems, production objectives often cannot be achieved.
The types of chillers are divided into two main categories vapor compression and vapor absorption chillers. vapor compression chillers use an electrically driven mechanical compressor to force a refrigerant around the system while vapor absorption chillers use heat to move the refrigerant around the system.
Vapor compression chillers are the most commonly used and fit into two subcategories: air chillers and water chillers. Let’s take a quick look at how each of these work, their applications, and the pros and cons of each.

Both air and water chillers have the same components: an evaporator, a compressor, a condenser and an expansion valve. Furthermore, the mechanics for both are very similar. The chillers compressors push a refrigerant around the inside of the chiller through the condenser, the expansion valve, the evaporator, and back to the compressor.
The primary difference between air and water chillers is how the unwanted heat is ejected. Air chillers us air to remove heat while water chillers use, you guessed it, water.
Air cooled chillers use air to remove heat by using fans to force air across the exposed tubes of the condenser. While air chillers require more energy than water-cooled chillers, they can be a great option when it comes to stationary cooling. Air chillers are easy to instal and typically can be installed outside a building (no extra space requirements). Compared to water chillers, air chillers are more prone to blockages and recirculation issues.

Water chillers remove heat by pumping water through a sealed condenser and dispersing it through the cooling tower. Water-cooled chillers are typically more efficient than air-cooled chillers. Using water evaporation to dissipate heat uses significantly less energy than blowing air across a hot surface. This is thanks to water’s high heat capacity. Additionally, water chillers tend to last longer than air-cooled chillers.
Air-Cooling and Water-cooling chillers are further categorized by the type of compressor technology used.
The series water chiller adopts efficient semi-closed screw compressor. the compressor adopts a 5:6 asymmetric high-efficiency screw rotor, which is graded or steplessly energy regulated. It is automatically adjusted according to load changes and is more energy efficient.
The series screw chiller adopts efficient semi-closed screw compressor. the compressor adopts a 5:6 asymmetric high-efficiency screw rotor, which is graded or steplessly energy regulated. It is automatically adjusted according to load changes and is more energy efficient.
The series air cooled screw type chiller cooling capacity from 85KW to 1550KW. This series units integrates the characteristics of many other products, using imported semi-closed screw compressors,supplemented by high-efficiency heat exchangers and adopts microcomputer controllers, which makes the unit compact, reasonable layout, convenient to use and maintain.
