Free cooling is the technique of accumulating the cold energy present in the night time atmospheric air in its natural state in the storage equipment. In the day, the cold energy is extracted from the storage equipment for cooling of the building by the use of mechanical ventilation system. In this, the heat exchanger built is of a shell and tube heat exchanger with the phase change material (PCM) which is present in the shell portion of the module and the way for flow of air is through the holes. The exchanger modules are placed one above the other with the air spacers in between every module. This heat exchanger arrangement is appropriate for application of free cooling where the variation of temperature is less. In this study, steady state heat transfer analysis is carried out for heat exchanger with one module and two air spacers. The CFD results are compared with the experimental results. To calculate the pressure drop over module and spacer, steady state flow analysis is used and flow and temperature variation in the module can also be calculated with steady state flow analysis. . The project is carried out for different configurations of the PCM module by changing the hole diameter and the thickness of the module.
