Why is the volumetric air compressor need to be cooled between two phases?

Answer 1

When you take the air ambient temperature and compress it , the temperature of the air increases. To compress hot air needs more energy. So they cool it and then compress it again Thus total energy needed will be less.

Answer 2

By cooling the air between the two stages you get the benefit of a smaller cylinder for the second stage than would otherwise be needed.

You also reduce the discharge temperature of the second stage resulting in less maintenance because the materials are subjected to temperatures that are not as high.

Finally if you look at the energy required to compress the air, it is less with the cooling of the air between stages.

Answer 3

When air is compressed by any means, it is heated. The amount of heat or temperature rise can be determined by the following formula Temp2 at Pressure 2 is equal to T1 times the ratio of P2/P1 raised to the 1.6 power. Where temperature is in degrees Kelvin and pressure is in mm Hg absolute.

Removing the heat between stages of a compressor, reduces wear on the compressor and downstream components.

Answer 4

By cooling the air you reduce the volume (phse one), this way you can have a larger amount of air at the suction side of the compressor. The compressed air increases temperature, you need to cool it down (phase 2).

Answer 5

To cool the gases between the first, and second stages. The cooler they are, the better the compression........and it stops the compressor from blowing up........

Answer 6

HMMMM. Lets see are you referring to the 4 stroke engine? After all a 4 stroke engine is a volumetric air pump in its simplest design. The intake stroke is cooler than the compression and power strokes that follow and the exhaust stroke expels the remnants so it to would be cooler than the compression and power strokes as well.

Answer 7

Question has such poor grammer & structure that I don't
even understand what is being asked...
