Title Of Article :
EXPERIMENTALLY INVESTIGATION OF PERFORMANCE OF A COMPRESSOR SUPPORTED BY HEAT ENERGY IN VAPOR COMPRESSED REFRIGERATION SYSTEM
Abstract :
In this study, a compressor, driven by external heat, was used in the vapor compression refrigeration system instead of an electrically driven compressor and the performance of this compressor was determined. R-134a, an ozone-friendly refrigerant, was used in the system. In the first test, the designed and constructed compressor was driven by electricity. In the second test, the heat energy and electricity were applied to the compressor at the same time. The results showed that COP of the system, in the first test, varied in between 2.77 and 3.49, COP of the system, in the second test, varied in between 2.11 and 2.02. In addition, in the tests which were carried out by applying heat energy, it was observed that the speed of the compressor increased by 4.5 % and the electricity consumption decreased 8.5 %.
