Summary

Opening and closing of suction and discharge valves are critical to determine the volumetric efficiency in the reciprocating compressor. The discharge and suction valves open due to the pressure differential and negatives effects, as back flow, may occur decreasing the compressor efficiency. Understanding the power consumption on the refrigerating cycle and its losses can contribute to obtain better compressors. Analyzing the PV diagram it is possible to obtain the work exerted on the gas during the compression cycle and also the losses on the suction and discharge valves. In this work it was measured the PV diagram of reciprocating refrigerating compressor synchronized with its valve functioning. Measuring the PV and the valve functioning, it is possible to get a better understanding of the valves losses and the gas back flow can also be completely verified.
