Experimental Investigation on Performance of Vapour Compression Refrigeration System with Integrated Sub-Cooling

Abstract

This paper presents an experimental investigation on performance of VCR system with integrated sub-cooling carried out by introducing counter flow tube – in – tube heat exchanger between compressor and condenser. The COP (coefficient of performance raised with condenser subcooling due to tradeoff between reducing compressor work and increasing refrigerating effect. Thermodynamic properties related with refrigerant effect like latent heat of vaporization and liquid specific heat were used to finding the superlative increasing in COP with condenser subcooling. Decreasing the condenser subcooling high latent heat of vaporization used in refrigerant. The performance and power required to run system is compared with conventional VCR System. The result shows that using heat exchanger as a pre cooler (or) Sub-cooler to condenser can improve 14% of COP and 27% Power consumption reduction when compared to the conventional VCR System.
