Environment-friendly Air Cooled Scroll Chiller
Environment-friendly Air Cooled Scroll Chiller
Product Description
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.
