Abstract:

Free cooling is a promising passive cooling technique that requires minimum or no energy for cooling the space. Free cooling can be achieved with the use of phase change material based thermal energy storage. An organic phase change material (PCM) with phase change temperature 350C is selected based on the climatic conditions of the selected location. A heat exchanger containing phase change material with selected geometry is tested by varying selected dependent variables, which are inlet airflow velocity and the orientation of the flat plates of the heat exchanger. In this paper, investigation results of an air-phase change material heat exchanger are presented along with its efficiency. It was observed that maximum heat exchanger efficiency of 74.07%was obtained.
