Abstract
Earth-air heat exchangers, likewise called ground tube heat exchangers, are an intriguing strategy to diminish vitality utilization in a structure. They can cool or heat the ventilation air, utilizing cold or heat gathered in the dirt. A few papers have been distributed in which a structure technique is depicted. The greater part of them depend on a discretisation of the one-dimensional heat move issue in the tube. Three-dimensional complex models, fathoming conduction and dampness transport in the dirt are additionally found. These strategies are of high unpredictability and regularly not prepared for use by planners. The temperature of earth at a specific profundity around 2 to 3m the temperature of ground remains almost consistent consistently. This consistent temperature is known as the undisturbed temperature of earth which stays higher than the outside temperature in winter and lower than the outside temperature in summer. At the point when surrounding air is drawn through covered funnels, the air is cooled in summer and heated in winter, before it is utilized for ventilation. The earth air heat exchanger can satisfy in both reason heating in winter and cooling in summer. With the help of ETHE we can reduce the energy consumption required for space. The ground temperature variation used in different researches is also reviewed in this paper as an important part of identifying potential ETHE implementations. Design and performance aspects of the ETHE are also reviewed. Finally, this paper summarizes the potential and benefit of ETHE implementation in the Indian climate for cooling and heating applications to reduce the energy used in buildings and greenhouse gas emission.
