Smaller horsepower rotary screw compressors 40 hp and below are not typically available water cooled.
Air compressor cooling air flow.
As the compressed air cools up to 75 of the water vapor present condenses to a liquid and can be removed from the system.
These values should be kept in mind when evaluating any compressor cooling system.
When selecting larger air cooled compressors the amount of cooling air flow required is proportionally larger and therefore the limitations of cooling air inlet and cooling air discharge in the room will need to be considered.
The main stop valve should be situated in the water pipe inlet header and flow regulating valve in the supply line to each cylinder intercooler and aftercooler means parallel water circuit.
The more compressed air is cooled inside a compressor s inter cooler and aftercooler the more energy efficient the compressor will be and the more the water vapor will be condensed a water cooled compressor installation puts little demand on the compressor room ventilation system as the cooling water contains in the form of heat approximately 90 of the energy taken up by the electric motor.
01 the cooling water piping connections to the compressor cylinder intercooler and aftercooler should be arranged as shown in the general arrangement drawing and water piping diagram.
