Reciprocating
Rotary types include ,Centrifugal, screw, scroll
1- Rotary vane compressors
Larger models have eight or more blades and do not require inlet or outlet valves. The blades are held in close contact with the outer shell by centrifugal force, and sealing is improved by the injection of lubricating oil along the length of the blades.
2- screw Compressor
The scroll compressor is built only in hermetic enclosed models. The dynamic and gas pressure loads are balanced so that it is free of vibration. It is currently available in cooling capacities up to60 kW, and is being made in larger sizes as development proceeds.
3-Dynamiccompressors
Centrifugal machines can be built for industrial use with ammonia
And other refrigerants, and these may have up to seven compression
Stages. With the high tip speeds in use, it is not practical to build a
Small machine, and the smallest available centrifugal compressor
For refrigeration duty has a capacity of some260 kW. Semi-hermetic
Compressors are made up to7000 kW and open drive machines up
to21000 kW capacity.
