a) Constant Speed Centrifugal Chiller: Speed of the impeller wheel is constant while compressing the refrigerant vapor by the application of Centrifugal Force.
b) Variable Speed Drive Centrifugal Chiller: Speed of the impeller wheel is variable while compressing the refrigerant vapor by the application of Centrifugal Force.
c) Constant Speed Screw Chiller: Constant Speed for squeezing refrigerant between two rotating helical rotors.
d) Absorption Chiller: Absorption fluid is evaporated in a low pressure system to remove heat.
