Experimental Performance Determination of COP and TR for R12 Vapour Compression Refrigeration System

Abstract

Experiments stand performed for investigating influence of R12 refrigerant on system performance evaluation in terms of COP and TR. Temperature and pressure got measured by different temperature and pressure gauges mounted at several predetermined locations. Additionally, power consumption by refrigeration system also got measured from the installed energy meter readings. Altogether, it summarizes the tabular inscriptions of the variations of COPth, COPact and COPrel with TR for R12 refrigerant. Besides, it also demonstrates the graphical representation of the corresponding variations of COPth, COPact and COPrel with TR for R12 refrigerant. As expected, it stands observed (from both the stated table and figure) that both COPth and COPact increase with TR, however, the COPrel decreases with the same for said R12 refrigerant. Furthermore, the stated variations of COPth, COPact and COPrel with TR remain observed as approximately linear, independently. That’s why, both COPth and COPact stay directly proportional to TR, however, the COPrel stays inversely proportional to the same because of approximately linear relationship between the COPth, COPact and COPrel with TR, independently.
