Description:
The performance of a vapour compression refrigeration system depends greatly on the spatial arrangement of the components, properties of the refrigerant and lubricant. Numerous models have been developed by using these properties to predict the performance of the vapour compression refrigeration system. The usual ideal gas model does not yield accurate results due to its limited range. In this study, an analytical real gas model has been developed for heat transfer in the evaporator and work output rate of compressor to achieve the coefficient of performance (COP) of the system. This real gas model is validated against the investigational data and the end result obtained was consistent with an error band of 10% for exhaust temperature and 7% for COP. This model can be used to predict the COP of any vapour compression refrigeration system, given that the thermodynamic properties of the working fluid and required dimensions of the system are known. However, it cannot be extended t...
