What is intercooling in compressor?

An intercooler is a heat exchanger that functions to remove heat from the air generated by an air compressor. An efficient intercooler will restore the temperature of compressed air to near environmental levels.

What is intercooling process?

Intercooling is the process of cooling the heated (and pressurized) intake air after the turbocharger or supercharger before it enters the combustion chamber.

What is intercooling and effect of intercooling?

This method of increasing the net work from the gas turbine engine is termed as multi-stage compression with intercooling. Process 2-3: Working fluid is cooled to the initial temperature in a heat exchanger which is termed as intercooler.

What is the purpose of intercooling in double stage reciprocating air compressor?

The purpose of an intercooler is to reduce the work input given to the compressor to reach the same pressure as can be reached by a single compressor.

Why intercooling is done?

Intercoolers are used to remove the waste heat from the first stage of two-stage air compressors. Two-stage air compressors are manufactured because of their inherent efficiency. The cooling action of the intercooler is principally responsible for this higher efficiency, bringing it closer to Carnot efficiency.

What is the advantage of intercooling?

To avoid excessive temperature rise associated with higher compression ratios, and to approach isothermal compression. Saving in power. Volumetric efficiency is increased.

What is the general effect of intercooling?

An intercooling regenerative cycle can increase the power output and the adiabatic thermal efficiency. This combination provides an increase in efficiency of about 12% and an increase in power output of about 30%, as indicated in Figure 2-16.

What is perfect intercooling?

Answer: Intercooling : In perfect intercooling the temperature of air after passing out of intercooler is same as that of the temperature of air before compression of LP cylinder.

How does intercooling reduce compressor?

The addition of intercoolers in gas turbine cycles reduces the compression work, and this is achieved by dividing the compression processes into two or more stages, and the exit air/gas from each stage is cooled by the intercooler/heat exchanger to the minimum cycle temperature.

Where is an intercooler located?

Whilst in theory, air-to-air intercoolers can be located anywhere between the turbo and the engine, they are most effective where there is better airflow, and are usually placed at front of the vehicle, behind the grille.

How does intercooler increase efficiency?

Hot air is less dense than cool air, which reduces its combustion efficiency. However, by installing an intercooler between the turbocharger and the engine, incoming compressed air is cooled before it reaches the engine, restoring its density to give optimum combustion performance.

What is the effect of intercooling in gas turbine?

Intercooling between the stages in the compressor leads to a decrease in the compressor work input therefore it will also help to increase the work ratio of the gas turbine plant resulting in a decrease in the thermal efficiency, but the scope of regeneration will increase.
