Analysis of Vapour Compression Refrigeration System Using Matrix Heat Exchanger

ABSTRACT Power utilization is a key fear in vapor compression refrigeration system .The objective of this research paper is to study the performance of a vapour compression refrigeration system with and without a matrix heat exchanger. As this research aims to augmentation of performance of refrigeration system by subcooling method with matrix heat exchanger, matrix heat exchanger is considered by allowing for some design parameter. Matrix heat exchanger is of counter flow type, by one side liquid refrigerant from condenser flow and from other side water from the evaporator is circulated. In this research work matrix heat exchanger is connected to VCR system after condenser. Performance analysis is done. The testing is done on VCR system using R-134a as a refrigerant. The performance of VCR system is compared with and without matrix heat exchanger for unlike loads. The results show that performance of VCR system is improved using matrix heat exchanger. The system works safely and normally. It is found that theoretical C.O.P of the system with matrix heat exchanger increases by 13.68% (average) and actual C.O.P also increases by 3.14% (average).
