Receip or Piston type compressor are used for large duty cycle work (A/c or other equipments), energy hungry but last longer (Heavy Duty). Where as rotary compressor are energy efficient with higher ( Energy Efficiency Ratio) but lower duty cycle and shorter life. Selection of compressor are based on the nature of application. Normally, for room A/Cs with capacity less than 3 ton, most companies offer rotary compressor due to it's EER and less duty cycle. For heavy duty A/Cs, recip or piston compressor best suited.
A rotary vane pump uses positive displacement to propel liquids. The inner rotor is offset from the outer cavity which creates an eccentric motion. The vanes are moveable which creates the difference is pressure needed to move the liquid.
Reciprocating compressors are positive displacement in machines. However, separable compressors have higher maintenance costs.
To provide moisture free compressed air to a pneumatic system that operates pneumatic motors.
1000 atm
use rotating members to compress and increase the pressure of the air.
Same way a non rotary compressor works
spring type rotary compressor
A rotary compressor has screws or gears that compress a gas. A reciprocating compressor has a piston in a cylinder compressing the gas.
working principle of a compressor
You can purchase a rotary screw compressor from the Compressor World website. Alternatively, you can also purchase this item from the BuyQuincy website.
A rotary compressor is like a car engine, with pistons, rods, sleeves, valves, etc. A screw compressor has two screw type rotating parts that squeeze the refrigerant as the screw threads get tighter and tighter. They have long life potential.
Rotating axial compressor.
Centrifugal Compressor and Rotary Compressor is preferred with refrigerant R-113.

Depending on the refrigerator, it's TYPICALLY a "rotary vane" compressor, but that's not always the case.
