A refrigerant system is provided with at least two sequential stages of compression. In a single stage compressor the air is compressed one time; in a two stage compressor the air is compressed twice for double the pressure. It turns out that, as long as P 2 >> P 1, the power savings more than repays the increased costs associated with buying a more expensive 2-stage compressor and the intercooler heat exchanger as well ! The main difference between a single and 2 stage air compressor is the number of times that air gets compressed between the inlet valve and tool nozzle. An intercooler is provided between first and second stage. In a two-stage compressor, air is partially compressed using isentropic compression, and then cooled in a heat exchanger, called an intercooler. We use intercooler in 2 stage compressor to increase efficiency and reduced power consumption. Experimental data of compressor with existing intercooler connected to the pipe line were taken as the reference for CFD analysis. There are six major components of two stage compressor. It uses two pistons. An intercooler is positioned intermediate the two stages. The air receiver has a drain valve, safety valve, pressure switches and a discharge valve. The intercooler exit temperature is thereby increased, with two main consequences for engine operation: 1. The refrigerant flowing through the intercooler is cooled by a secondary fluid such as ambient air.

Dhakane, 2M.S.Joshi The intercooler improves the compressor’s efficiency. Design Of Intercooler In A Two Stage Reciprocating Compressor - posted in Industrial Professionals: i have been assigned to validate the design of existing intercooler, please suggest me the approach. Reduced LP compressor surge margin due to decreased mass flow: The reduced intercooling means the HP compressor referred speed and hence referred flow are reduced by the higher inlet temperature. A vapor/liquid injection function is also provided for the refrigerant system. I hope this has piqued your interest. In the two-stage reciprocating air compressor, the air compresses two times. Two Stage Air Compressor. regards The second stage compressor has three alternative pulleys to vary the pressure ratio between the two stages. Both stages are connected by vee-belts to the same motor with an advanced inverter. what is more imporatant in intercooler design whether it is dew point below which air to be cooled or percetage of moisture to be removed. One uses for air compression from these pistons while other uses for pumping compressed air from one cylinder to the second cylinder. 1) Piston 2) Piston Ring. The “ribbed” air lines between cylinders and into the tank on the following Husky compressor are an example of a basic intercooler. A two-stage air compressor unit having an intercooler and aftercooler placed in side by side relationship to form an integral unit which is cooled by forced air blown by a motor driven fan and which has the inlet and outlet parts located in such a manner that little, if any, heat transfer occurs between the intercooler and the aftercooler so that greater cooling efficiency is realized. is shown in thetable 4.
