Investigation Analysis on the performance improvement of a vapor compression refrigeration system

The principal objective of the paper is to modify vapor compression refrigeration system by connecting heat exchangers thereby heating and cooling of water is done simultaneously. The vapor refrigerant is supplied to the hermetic sealed compressor where the refrigerant gets compressed to a temperature of 100-120 degrees C. The compressor is connected to a counter flow heat exchanger. Experimentation is carried out to design and manufacture a modified vapor compression refrigeration system. The main parameters considered during the fabrication process are connection of a compressor to a hermetically sealed compressor, keeping polyurethane foam as insulating material, adjusting the capillary tube and finned evaporators. The operations considered during the experimentation are bending, brazing and arc welding process. After the experimental setup has been done the system is checked for the performance parameters by using R-22 and R-407. The results are plotted for heating and cooling temperatures with respect to time.
