What are the common classifications of chillers?

1. According to the form of compressor: piston chiller, screw chiller and centrifugal chiller.

2. According to fuel type: fuel oil type (diesel, heavy oil) and gas type (kerosene, natural gas).

3. According to the condenser cooling method: water-cooled chiller and group air-cooled chiller.

4. According to the form of energy utilization: cold-only heat pump type, heat recovery type, and dual-function type with only cold ice and cold storage.

5. According to the cold water outlet temperature: air-conditioning type (7 degrees, 10 degrees, 13 degrees, 15 degrees) and low temperature type (-5 degrees to -30 degrees).

6. According to the sealing method: open type, semi-closed type and fully closed type.

7. According to the refrigerant: water-cooled chiller, brine chiller, glycol chiller.

8. According to different energy compensation, it can be divided into electric power compensation (compression type) and heat energy compensation (absorption type).

9. According to refrigerant: R22, R123, R134a

10. According to different heat sources (absorption type): hot water type, steam type, direct combustion type.
