What is the purpose of an interstage cooler?
An intercooler is a heat exchanger used to cool a gas after compression. Often found in turbocharged engines, intercoolers are also used in air compressors, air conditioners, refrigeration and gas turbines.
Why do you have interstage cooling in compressors?
If an intercooler is installed between cylinders, in which the compressed air is cooled between cylinders, then the final delivery temperature is reduced.
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 intercooling in compressor?
What Is an Intercooler? 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 interstage compressor?
In classical thermodynamics, the interstage pressure of an ideal gas minimizing the compression work of a two-stage compressor with intercooling corresponds to the geometric mean of the suction and discharge pressures [8,9,10,11].
Do intercoolers need coolant?
Intercoolers of this type depends on the efficient circulation of a liquid coolant, which in turn, requires a supply of liquid coolant, a circulating pump, hoses, a reservoir to store the coolant, and most importantly, a heat exchanger to remove heat from the stored coolant.
What is interstage pressure?
The interstage pressure, Pi, is obtained using the equation: Pi=Ps-u ×PRstage. where, Ps-u is the suction pressure of upstream stage. (Note: Each pressure value is in absolute units.) Multistage compressors are thus designed and built to achieve the above conditions.
How much HP will an intercooler add?
The usual rule of thumb is to allow 6 to 7 square inches of internal intercooler flow area for every 100 hp of engine output, but this can increase by up to 40 percent with really dense internal fins.
Does a bigger intercooler increase power?
It also makes the compressed air denser as it enters the intake manifold, which causes a richer air-to-fuel mix in the engine’s cylinders. The result is increased power output. So, the answer to the question is yes! An intercooler does help to increase horsepower.
Will intercooler increase horsepower?
How much pressure is in an intercooler?
For good solid performance, the pressure loss across the intercooler ought to be kept to less than 1.0 to 1.5 psi. If any pressure in excess of 4 psi is measured, then the intercooler is not suited for the job and certainly harming the performance.
