Abstract

The problem of energy and water shortages is increasing worldwide due to population growth and climate change. Also, desalination technology is an intensive energy process to produce fresh water from salty water. This paper presents an innovative system for an adsorption desalination-cooling system to improve the system’s performance. The new system consists of four beds, a condenser, and two evaporators, which provide a relatively high adsorption cycle performance for freshwater production, in addition to a cooling effect. This paper also compares the proposed adsorption system performance with the conventional adsorption desalination systems. The new adsorption desalination system is simulated through a validated MATLAB model based on the author’s previous experimental work. The novel system produces a maximum possible rate of freshwater of 20.5 m³/ton of silica gel per day with a gain output ratio of 0.85, along with a cooling effect of 220 W/kg of silica gel with a coefficient of performance of 0.42. The utilization factor of the proposed system is 1.27. The results also showed that the cost of producing 1 m³ of freshwater using solar energy is 4.24 $, which is considered lower than the cost of water production in the traditional system by about 40 %.

期刊介绍： Thermal Science and Engineering Progress (TSEP) publishes original, high-quality research articles that span activities ranging from fundamental scientific research and discussion of the more controversial thermodynamic theories, to developments in thermal engineering that are in many instances examples of the way scientists and engineers are addressing the challenges facing a growing population – smart cities and global warming – maximising thermodynamic efficiencies and minimising all heat losses. It is intended that these will be of current relevance and interest to industry, academia and other practitioners. It is evident that many specialised journals in thermal and, to some extent, in fluid disciplines tend to focus on topics that can be classified as fundamental in nature, or are ‘applied’ and near-market. Thermal Science and Engineering Progress will bridge the gap between these two areas, allowing authors to make an easy choice, should they or a journal editor feel that their papers are ‘out of scope’ when considering other journals. The range of topics covered by Thermal Science and Engineering Progress addresses the rapid rate of development being made in thermal transfer processes as they affect traditional fields, and important growth in the topical research areas of aerospace, thermal biological and medical systems, electronics and nano-technologies, renewable energy systems, food production (including agriculture), and the need to minimise man-made thermal impacts on climate change. Review articles on appropriate topics for TSEP are encouraged, although until TSEP is fully established, these will be limited in number. Before submitting such articles, please contact one of the Editors, or a member of the Editorial Advisory Board with an outline of your proposal and your expertise in the area of your review.
