COMFORT COOLING TOWARDS A GREEN FUTURE BY

•Earth Air Tunnels have been used successfully at TERI retreat at Gurgaon, Gul Pahari, Delhi, where the underground tunnels serve the living quarters. The living quarters are maintained at temperatures approximately between 20 to 300 C round the year. • The system utilizes tunnel, air intake ports and dehumidification. The treated air is passed to the spaced through ducts and supply grills

Performance enhancement of earth air tunnel heat exchanger

Earth Tubes are a passive technology that enable the transfer of ground source energy to heat or cool ventilation air. They are standard concrete tubes that run underground and precondition the temperature of incoming air before it enters the building. They reduce the energy required to heat or cool the building.

Role of Earth Air tunnel systems to reduce the building

Earth Air Tunnels This technique is used both for passive cooling as well as heating of buildings, a feat which is made possible by the earth acting as a massive heat sink. Summer as well as winter variations die out rapidly with increasing depth from the earth's surface.

CFD ANALYSIS OF THERMAL INFLUENCE ZONE OF EARTH AIR TUNNEL

EARTH AIR TUNNEL SYSTEMS. Working Principle Earth–air tunnel heat exchanger (EATHE) is one of the passive systems, which utilizes the undisturbed ground temperature below the earth’s surface to heat and cool the buildings. At a depth of 4 metres below the ground, the earth's temperature remains more or less constant throughout the year. This temperature is nearly equal to average

An open loop, underground air tunnel system cools or heats the ambient air passing through it. This air is then introduced directly into the conditioned space of a building. In order to reduce the required tunnel length, a closed loop system may be used. In this system, the air from the conditioned space, with some ventilation air, is recirculated through the underground tunnel. Open and

Solar Passive Techniques Earth Air Tunnel

Su et al. developed a numerical simulating model for the deeply buried air-earth- (rock-) tunnel system, in which a 1D implicit transient convection-diffusion submodel describes the air temperature and humidity, and a 1D transient explicit heat conduction submodel computes the rock temperature. The accuracy of this numerical model has been verified by comparisons of temperatures of the air and
