Optimization Strategy of Sustainable Concentrated Photovoltaic Thermal (CPVT) System for Cooling

Abstract

Renewable energy resources are susceptible to intermittent power supply and their standalone operation has prime importance for steady power supply. Solar energy resources have high global availability and potential among all energy sources. Most of areas with high solar energy potential have either dry hot or tropical climate. A major portion of primary energy supply for such area is utilized in their cooling energy needs. In this chapter, a sustainable approach for cooling needs has been proposed using solar energy based highly efficient concentrated photovoltaic (CPV). A combined cooling system, based upon mechanical vapour compression (MVC) and adsorption chillers have been considered. The MVC chiller utilizes the produced electricity by the third generation multi-junction solar cells (MJC). However, adsorption chiller is operated with thermal energy recovered from the cooling of CPV system, which also increases the system efficiency as high as 71%. To handle intermittency, hydrogen production is used primary energy storage system, along with the hot water storage. The complete system configuration is then optimized for standalone operation with optimum components size and minimum cost, using microgenetic algorithm according to proposed optimization strategy.

A Universal Mathematical Methodology in Characterization of Materials for Tailored Design of Porous Surfaces

“…The adsorbent-adsorbate pair and their unique interaction according to available adsorption energy sites result in the processes mentioned above and the energy transformation (Antonelli et al, 1992;Zhao et al, 1998). For adsorption cooling, the bulk energy is lost when adsorbate molecules are attracted to adsorption sites, resulting in bulk temperature loss (Uyun et al, 2010;Burhan et al, 2019b;Chen J. L. et al, 2020). Similarly, in adsorption desalination, pure adsorbate molecules are separated from bulk fluid due to their attraction toward the adsorption sites.…”

“…Energy is an essential need for the sustainability of the modern world. However, with the recent Paris Agreement on climate change between 192 states and European Union, the target has been set to limit the global temperature increase, below 2 o C through expanding the use of renewable energy resources [1][2][3][4][5][6][7][8][9][10][11][12]. Solar energy is considered having the highest energy potential, to meet the current global energy needs [13][14][15].…”

Solar energy is considered having the highest energy potential, to meet the current global energy needs [13][14][15]. Despite its availability as low grade radiative and thermal energy, it can be easily converted into high-grade source of electrical and thermal energy by using solar cell and concentrators [16].…”
