Analysis of Earth Air Heat Exchanger (EAHE) for Storage system

Niraj R. Shingala, Dr. Ajit Kumar N. Shukla


Geothermal energy is one of the potential alternative sources of energy which has been successfully catering to both industrial and domestic energy requirements. The temperature of earth at a certain depth about 2 to 5 m the temperature of ground remains nearly constant throughout the year. This constant temperature is called the undisturbed temperature of earth (EUT) which remains lower than the outside temperature in summer. In this research, a one-dimensional model of the EATHE systems for Storage system using with a set of simplified design equations. The method to calculate the earth’s undisturbed temperature (EUT) and other higher accuracy in the calculation of heat transfer. A longer pipe of smaller diameter buried at a greater depth and having lower air flow velocity results in increase in co efficient of performance (COP) of the EAHE system.
