Development of a Combined Evaporative Cooling System with Eco-Friendly Nozzles and Encapsulated Phase Change Material

Power outages affect the functionality of commercial and industrial air conditioners. The processes followed by AC units and emissions impacts on global climate. Recently, Indian government banned imports of AC and refrigeration products and components which were supplied from China. But Indian Government understands people’s need for cooling and realizes that an exponential rise in demand for cooling is inevitable. Considering such critical situations, we have designed an eco-friendly air-conditioning module which contains PCM-based heat exchanger for indirect evaporative cooling and eco-friendly designs for direct evaporative cooling. Eco-friendly designs of convergent shape are manufactured by considering software analysis results and by following the same steps required for manufacturing of soil pot. Software analysis results of the whole experimental setup showed a temperature reduction in the range of 7–10 °C. Required humidity is achievable by controlling some parameters. Material used for this project is completely economical and easily available. Poisonous and harmful refrigerants and greenhouse gases are not used in this project. It is smaller, compact, economical and efficient. Also, there are no noticeable direct and indirect emissions from this experimental setup. This research paper includes software analysis for studying cooling effect and humidity control, design and performance analysis of PCM-based heat exchanger and related research work to achieve desired temperature reduction.
