Solar preheat with significant Thermodynamics Parameter Scrutiny of Energetic, Economic and Environmental Analysis in Tri-generation System.

Abstract

The solar tri-generation system can enhance the use of solar energy in residences. In this paper, an evaluation of the performance and operating parameters of an absorption sub-cooled compression hybrid cooling (ASCHC) configuration based on the pairing of photovoltaic thermal (PVT) collectors is presented. The work includes the multi-culmination fractionation and chiller originator to the Natural Rankine sequence system to evaluate the critical thermodynamic parameters such as irreversibility ratio, fuel depletion ratio, improvement potential, and total exergy loss of the system. The study was carried out using the first law and second law of thermodynamics applied to each component of each system. Solar absorption-subcooled compression hybrid cooling system (SASCCHC) is a novel cooling system that consistently meets the demand of cooling load with solar irradiance change. It is a very efficient and economical solar cooling system. The hybrid system’s performance is higher due to the improvement of the evaporator temperature of the absorption subsystem. However, SASCCHC is complicated in terms of working process and performance simultaneously due to the coupling of the absorption and compression subsystems. In the prior methodologies, there is a lack of electrical output performances of PVT collectors. It is found that previous studies do not consider the changeable storage tank temperature, exergy destruction rate estimation, and scrutinizing of thermodynamic parameters, which are significant potential. The present work incorporates the parabolic channel collector to estimate the exergy destruction rate, which increases the output working fluid temperature to a wide range significantly. Due to this, the proposed analysis’s outcome proficiently increases fuel depletion ratio and decreases exergy loss.
