Mathematical Design and Simulation of Double Acting Reciprocating Compressor

Many compressor applications require maximum compressed air discharge in the minimum time. The system analysis considered parameters such as efficiency, free air delivery, time for filling the tank, and running costs. Based on the instruments utilized in sectors that typically run at a maximum pressure of 9 kg/cm2, compressed air is utilized. The analysis involved designing a double acting reciprocating compressor based on the available specifications of a single acting reciprocating compressor (Model - SS 05090 HN), ELGI make, based on the tools used in the industries to achieve the same specification to pressure 9 Kg/cm2 at 925 rpm for piston displacement of 0.606 m3/min(21.4 cfm). To fill a receiver tank of 220 liters for the single acting compressor, it takes 29.87 seconds, whereas the double acting compressor takes only 9.4964 seconds. This demonstrates that the discharge rate of the double acting compressor is almost twice, and the running cost is reduced by Rs. 242.13 /- for eight hours of operation per day. This analysis highlights the superior performance, cost-effectiveness, operational efficiency, and financial viability of the double acting reciprocating air compressor, showing that it yields optimal results compared to the single acting reciprocating compressor.
