Solar-assisted absorption cooling systems with thermal control

Project: Research

Project Details


Due to the prolonged summer seasons and economic advancement as well as population growth in the Kingdom of Saudi Arabia (KSA), electricity consumption is progressively increa...asing, where the energy consumption of the building sector (residential, commercial) accounts for about 50% of the total energy generation. Moreover, about 70% of energy consummation in the building sector is consumed by Air Conditioning (AC) systems. On the other hand, Saudi Arabia has the advantage of exploiting renewable energy, mainly solar energy that can be tapped to fulfill part of its energy needs while boosting the economy. However, one of the major challenges facing the use of solar to produce energy is the discontinued availability of sunlight, which is indeed dependent on the extent of the daytime and location. Therefore, this project is about using energy storage as the main solution to the intermittency of solar energy production or generation. Hence, the main objective of this project aims to study the impact of the integration and control strategy of thermal energy storage on the performance of solar-assisted absorption cooling systems using combined simulations. Although the systems under this project will consist of solar collector fields, absorption chillers, and hot and cold-water storage tanks, the control application for all these systems will be integrated in a combined manner. Furthermore, the applicability of this study will be developed and demonstrated using a detailed thermodynamic model of the integrated control systems, and a combined simulation between MATLAB/Simulink and Engineering Equation Solver (EES) software tools. The merits and demerits of integrating cold and hot thermal energy storage options under different control strategies as well as their economic potentials will also be evaluated in this study. Considering the enormous contribution of energy consumption in buildings for thermal comfort, the outcomes from this study are expected to be an additional guide for the implementation of solar-assisted cooling systems towards the design of net-zero energy buildings.
