ABSTRACT

The performance of Vapor compression refrigeration system (VCRS) depends on the performance of all its components like compressor, condenser, expansion value and evaporator. The current project is involved in analysis of the effect of condenser length on the performance of on VCRS. Condenser is a heat exchanger where heat transfer takes place between the super-heated refrigerant received from the compressor and the cooling medium of the condenser. The condenser removes the heat from refrigerant which received in two stages. Heat is received by the refrigerant in the evaporator and also heat is added by the compressor during compression. The refrigerant is first cooled to saturation and then condensed to liquid state. In Domestic refrigerator the condenser coil is used to discharge the heat from the refrigerant after operating the compression to the atmosphere. In this present work a condenser coil with different lengths are tested. In the present work condenser with variable length ((9.45m, 9.75m, 10.06m) has been used for this investigation by keeping the diameter as constant and compared with existing condenser of 9.14m length. The results shown that 9.75m length condenser coil gives optimum performance than the remaining which gives higher COP, higher heat rejection, refrigeration effect and lower power consumption.
