Dr N V V S Sudheer Associate Professor, R V R & J C College of Engineering, Guntur India ABSTRACT In this project, experimentation is done on Vapour Compression Refrigeration System [VCRS] as the COP is high for this system and it is the present trend of the HVAC in the domestic industry. This study presents investigation of best suited refrigerant and insulation combination for gas pipeline and liquid pipeline of a split air conditioning system. Analysis are performed for R22-Chlorodiflouromethane, a HydroChloroFlouro Carbon refrigerant, which has been using in the present world that cause both global warming and ozone layer depletion and R410a, mixture of di- flouromethane and pentaflouroethane, a Hydroflouro carbon refrigerant, which is future of HVAC which reduces the effect of ozone layer depletion [ODP] and Global Warming Potential [GWP].For these two refrigerants, we had found out the best insulation suitable as insulation also affects the COP of air conditioner, which has been observed from the literature. Minimizing the temperature of refrigerant in suction line helps condensing unit work more effectively intern the system performance increases. This reduces the overall power required for working of air conditioner, thereby reducing the maintenance cost of system. Also, it helps the manufacturer to provide best type of insulation for the system at reduced cost thereby reducing overall cost of VCRS.To perform the experimental comparison, 16 tests were carried out for 5 times with each refrigerant Insulation combination. From analysis it is observed that, COPA for NRF+AF gives highest value for R22 and R410awhen compared to various insulation materials. Power required for VCRS is greater while using R410a than R22. So In this work the main energy parameters such as COP and work required for compressor are analysed and discussed.
