A free cooling chiller is a type of cooling system that utilizes ambient air temperature to provide cooling without the need for mechanical refrigeration.
It works by drawing in cool outdoor air and using it to lower the temperature of the cooling medium, such as water or glycol, which is then circulated through the building or process equipment to remove heat.
The key feature of a free cooling chiller is its ability to take advantage of the natural cooling capacity of the environment, reducing or eliminating the need for traditional mechanical cooling methods. This results in significant energy savings and lower operating costs.
Free cooling chillers are commonly used in applications such as data centers, industrial processes, and commercial buildings with a year-round cooling load.
Key Features of VENTTK Free Cooling Screw Chiller
1. Cooling capacity from 260~550kW, providing efficient cooling for various cooling loads.
2. Hanbell Screw compressor, ensuring efficient operation and long-lasting performance.
3. Free cooling function can start at 0℃ or 5℃, when the outside temperature is within this range, the chiller can use the cool outdoor air to supplement or replace mechanical refrigeration, significantly reducing energy consumption.
