Abstract
Solar energy is probably cleanest and most beneficial energy kind of renewable energy available. Solar energy is the intermediate source of energy and hence there is mismatch between energy demand and generation. This gap can be reduced by energy thermal storage system. It can be stored as latent heat or sensible heat or combination of latent heat and sensible heat by phase change material. Latent heat concept is most beneficial way for thermal storage compared to sensible concept in small temperature difference. This study is accomplished to familiar various kinds of thermal energy storages which are commonly used in solar air heater and it also carried out to analyze solar air heater. Comparative study has been carried out for various kinds of solar air heater with taking care of solar collector.In PCM based solar air preheater;Phase change material absorbs and releases thermal energy in order to maintain constant temperature as per requirement. Design and analysis are also done to control the temperature during whole day. Main objective of this study is to reduce usage of harmful resources which is beneficial to environment.
