Air compressor compression method

1. Isothermal compression: A compression method that keeps the temperature constant when the gas is compressed.

2. Adiabatic compression: A compression method in an adiabatic state that neither heats nor removes heat from the outside.

3. Polygonal curve compression (compression method actually used): It is a compression method that dissipates part of the generated heat and exchanges heat with the outside, which is different from isothermal compression and adiabatic compression.
