Abstract


In this paper we discussed about the improvement in efficiency of a domestic refrigerator using diffuser by connecting it in the compressor outlet. Here refrigerant, 134a is used to operate the cycle. Diffuser angle is taken as 10o,11o,13o .initially Coefficient Of Performance was calculated without the diffuser and after that diffuser is connected with the refrigerator and the Coefficient Of Performance was calculated. Here the parameters like the temperature and pressure are considered. After calculating the coefficient of performance the cop with diffuser is compared with the cop without the diffuser and the results are tabulated. Here the power consumed by the refrigerator will be reduced for the same refrigeration effect. The result of this analysis cop was increased from 2.52 to2.59.
