Abstract :

A Thermal Energy Storage system (TES) has the advantage of an efficient use of energy by reducing the imbalance of an energy demand between daytime and night time. It is classified as sensible and latent heat storage systems. The latent heat storage system is superior to the sensible heat storage system since the former reduces the installation area and the expense due to a large thermal storage capacity and constant phase change temperature during freezing and melting processes. Phase Change Material (PCM) has been used as a medium of energy storage. An experimental investigation is carried out in the present research the setup includes a room of size 8x8x8 feet which is needed to be cooled using the heat exchanger and study the technical feasibility of using R 27 as PCM in a heat exchanger for free cooling applications. The charging and discharging experiments revealed the decline in the PCM temperature from 32°C to 29.5°C. The PCM showed a gradual increase in its temperature from 28°C to 29°C during the discharge process after which the increase was rapid.
