Environment-friendly Air Cooled Scroll Chiller

An Air Cooled Industrial Chiller is a machine that removes heat from a liquid via a vapor-compression cycle. Air cooled chillers are directly cooled by ambient air being mechanically circulated directly through the machine's condenser coil to expel heat to the atmosphere.

The two types of air cooled chillers are scroll compressor air cooled chillers and screw compressor air cooled chillers. Scroll compressors are used for the smaller air cooled chillers, and screw compressors are used for larger air cooled chillers and have a variable speed drive option for increased efficiency.

Here's a detailed comparison table between scroll compressor air-cooled chillers and screw compressor air-cooled chillers:

Feature	Scroll Compressor Air-Cooled Chillers	Screw Compressor Air-Cooled Chillers
Compression Technology	Scroll	Screw
Cooling Capacity Range	Typically up to 200 tons	Typically above 200 tons
Efficiency	High	Moderate to High
Part Load Performance	Good	Good to Excellent
Full Load Performance	Good	Excellent
Size	Compact	Larger
Noise Level	Low to Moderate	Moderate to High
Vibration	Low	Moderate to High
Maintenance	Simple and Easy	Complex and Higher Cost
Cost	Lower	Higher
Applications	Small to Medium-Sized Buildings	Medium to Large-Sized Buildings
Control and Modulation	Limited Modulation	Wide Modulation Range
Environmental Impact	Lower	Higher

Note: The comparison table provides general information and may vary depending on specific manufacturers and models of chillers. It's always recommended to consult with manufacturers or Huazhao professionals to determine the best chiller option for your specific application.
