Thermal modelling of PVT-CPC integrated vapour absorption refrigeration system

Abstract

In this paper, the single effect vapour absorption refrigeration (VAR) system is integrated with fully covered semi-transparent photovoltaic thermal-compound parabolic concentrator (PVT-CPC) collector. The thermal model of this integrated system has been obtained under constant mass flow rate mode of the collector. The thermal model is based on the basic energy balance of each component of the integrated system in terms of design and climatic parameters. Also, solar coefficient of performance (SCOP), refrigeration coefficient of performance (RCOP) and exergy coefficient of performance (ECOP) have been evaluated for the proposed integrated system. The numerical simulation have been performed for the climatic conditions of capital city of INDIA (i.e. New Delhi) with the help of MATLAB R2015a. From the results and discussion, it is found that PVT-CPC integrated with VAR system is most suitable for the self-sustained operation up to five hours for a typical day of summer month of New Delhi.
