Plant and Compressor Room Cooling
15 January 2015
Hot air is less dense than cool air. A typical screw compressor produces 6% less volume of compressed air at 300C than at 150C.
After compression the air is cooled in an after-cooler which uses oil as a heat transfer media. In extreme temperatures this oil becomes hot and the compressor will automatically shut down.
At high temperatures the oil will degrade faster and form ‘lacquering’ which can lead to blockages in the narrow bores of the heat exchanger circuit.
The heat from the oil is transferred to the compressor house typically using fan assisted heat exchangers. If there is inadequate ventilation this air can be recycled back into both the compressor intake and the oil cooler causing all of the above problems to occur.
EcoCoolers can be used to supply cool air using very simple installations at a fraction of the cost of air conditioning.
