In this paper an approach is presented to estimate the temperature , heat
transfer rate and heat liberation of a reciprocating air compressor . The
experimental work was performed by using double cylinder compressor
working by three stages to reach the final pressure. In the experimental work,
recording the final pressure for three stages ,and recording the temperature
at suction valve, delivery valve and the cylinder wall . In the theoretical part
a computer program used to solve model of single zone and depending on
step by step , and calculating the amount of heat liberation by analysis
pressure diagram ,the program depend upon the first law of thermodynamic
and gases .
The result that shown the maximum temperature inside compression
space from TDC , also the rate of heat liberation increased with increase of
compressor speed.
