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), refrig- eration coefficient of performance (RCOP) and exergy coefficient of performance (ECOP) have been eval- uated 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.

Introduction Recently, the absorption systems accomplish the energy saving challenges by application of low grade energy in the form of heat. Also, the absorption system protect environment from ozone depletion and global warming by the utilization of natural working pairs in their cycles. However, the performance of the systems are poor as compared to the compression refrigeration system [1]. But, the researches focuses to enhance their performance by the incor- poration of different methodology/technique [2,3]. Moreover, the absorption system will be more economical if it operates through solar energy [4]. The photovoltaic thermal system is however most suitable for the operation of vapour absorption systems [5]. Photovoltaic thermal (PVT) system refers to integration of pho- tovoltaic module and a conventional solar thermal flat plate collec- tor. This technology is used to enhance the overall utilization of solar energy. From this system, electrical energy and thermal energy both can be obtained simultaneously. First liquid type PVT collectors was designed by Wolf [6]. After that, this technology was improved by Kern and Russell [7]. Later on, a lot of research has been done in PVT technology to improve its performance. Hegazy [8], Shyam and Tiwari [9] have performed their studies on the performance of PVT air collectors. Chow et al. [10], Dubey and Tiwari [11], Mishra and Tiwari [12] have investigated the sen- sitive analysis on the performance parameter of PVT water collec- tors. Further, some authors have performed their research on the PVT integrated greenhouse dryers, roof and PVT facades etc. Shyam et al. [13] have performed an experimental validation of various performance parameter of partially covered series connected N- PVT collector operated at given mass flow rate. Recently, Tripathi and Tiwari [14] have conducted a comparative parametric analysis of low concentrated PVT collector by considering water and air as a working fluid. A lot of research has been done in the field of solar air- conditioning systems since the last few decades [15–17]. They have performed their investigation on solar absorption refrigera- tion system using either ammonia-water (NH 3 -H 2 O) or lithium bromide-water (LiBr-H 2 O) solution as a working fluid.
