The paper presents experimental data and results from a prediction tool for the performance of a desiccant loop cooling system. The experiments are performed under a variety of high humidity and hot ambient conditions and the system performance is described. One of the experimental conditions is typical of many Indian cities and the systems appropriate for those cities are established. A simulation program that can predict the performance of the desiccant loop is developed. The simulation results show that this system can work as effectively as vapor compression air-conditioning for certain ambient conditions whereas it can function as a pre-cooler to a vapor compression system under more severe conditions, resulting in a reduced power consumption. The results presented in the paper give a guideline to practicing engineers as to when a desiccant loop cooling system would be useful. A simple payback analysis and a lifecycle cost analysis shows that a desiccant cooling system with a waste heat recovery recuperator is an economically viable investment.

“…The advantage of this system is no pollution and using lowgrade energy. 89 Fong et al 90 used TRNSYS to investigate six different configurations of solar desiccant cooling systems, direct current powered vapor compression cycle powered by photovoltaic panels or thermal panels, and an absorption cycle. In the end, this whole system saved the energy up to 35.2% compared to conventional air-conditioning system.…”

Phase change material cold storage system could improve the efficiency and stability of the solar-powered airconditioning system and the building thermal environment. This article is a novel investigation of the phase change materials' usage in cold storage system and the phase change material cold storage working principles and features that are applied in the different solar-powered airconditioning systems as cited in the recent publications. This involves phase change material cold storage system, solar-powered airconditioning system, and the commercial market evaluation. To reduce the intermittent solar energy operation, the energy storage system is quite essential. Currently, the popular method is advanced phase change material cold storage. Using phase change materials in the energy storage systems, the heat exchangers and thermal control systems are the potential techniques. This article also reviewed the phase change material cold storage when applied in the solar-powered airconditioning system based on the previous study. This article could benefit further research in the solar-powered airconditioning field as integrated to the phase change material cold storage system and help to understand the commercial market development trend. For further studies, it was suggested that the optimal design of solar-powered cooling system could be employed by phase change material storage/release cooling dynamical control to improve the building thermal environment.

“…They also found that the process air and LiDs temperatures, solar intensity, and weather conditions were major factors affecting the effectiveness of the designed system. Kumar et al 12 performed an experimental investigation on a solar‐powered dehumidification system using a silica gel‐coated heat exchanger. It was observed that process air has been cooled by 8.5°C in dehumidification mode and heated by 13.3°C in humidification mode using an evacuated tube solar heat collector.…”

There has been a limited application of liquid desiccant (LD) dehumidification systems in space air conditioning until now. The key elements responsible for this restricted implementation are leakage of desiccant solution, corrosion of components, and solution carryover along with the processed air to the space to be conditioned. To remove these problems, an evacuated tube solar heat collector‐driven multichannel liquid desiccant air conditioning system has been proposed and experimentally investigated. In this study, dehumidification and regeneration rate, their effectiveness, cooling effect of the dehumidifier, and indirect evaporative cooling unit have been analyzed. The results obtained indicate that the process air has been dehumidified and cooled by 6.32 g kg−1 and 5.26°C, respectively. The regeneration rate and effectiveness have been obtained to be 0.26 g s−1 and 0.31, respectively. In terms of the cooling effect, the system output of 0.703 and 0.130 kW has been obtained from the dehumidifier and indirect evaporative cooling unit of the system, respectively. The proposed system validates the possibility of the novel solar‐powered liquid desiccant air conditioning system concept and provides growth and development of the LD air conditioning technology for space air conditioning.
