الملخص

An exegetical thermodynamic model was used to analyze and optimize reciprocating and scroll compressors of an air condition packaged unit. The experimental work was carried out using a 3.0 TR packaged unit manufactured by Carrier Company. The experimental and the analysis show that the exergy dissipative due to friction losses in bearings, suction, and discharge valves, and the transformation of power is larger than the heat losses. The exergy efficiency of the compressor was varying between (60-68) %. The scroll compressor was found to be better than the reciprocating compressor at an environmental temperature of 35℃ due to its low total losses which are 10% less than the reciprocating compressor ones. The heat loss percentages were 3% for scroll and 2% for the reciprocating of the total power input. The thermodynamic model has been shown to be reliable in dealing with a change in the environmental temperatures and such system components and size.
