Air cooling by conventional methods is practically everywhere, i.e. homes, hotels and hospitals. The temperature of the environment, increasing day by day due to heavy vapor compression systems used to meet the cooling load of buildings. The huge electricity is required for handling the cooling demands which are further destroying our natural resources. Efforts can be made to look for sustainable cooling system instead of using costly air conditioning systems. In this study effort is made to look for a low cost air cooling system for buildings by use of thermal energy of soil. The geothermal effect of soil can be very helpful for decreasing or increasing the temperature of the air. Using this method of cooling, the high grade energy demand, as well as environmental issues, can be minimized. The best use of geothermal energy can be made effective with the use of Earth Air Heat Exchanger method. The study of the air velocity may help in finding a maximum temperature drop of the air. With the rise in velocity to appropriate value it gives better results at a velocity of 2.5 m/s the maximum drop in temperature is 7.2 °C, for 3.4 m/s maximum drop is 6.5°C and at a velocity of 4.8 m/s drop is 4.0°C. Therefore the velocity of 2.5 m/s is cost effective and result oriented to a given Earth Air Heat Exchanger. The maximum average fall for a velocity of 2.5 m/s is equal to 5.4°C in the month of July for hot- humid climate.

Abstract


Air cooling by conventional methods is practically everywhere, i.e. homes, hotels and hospitals. The temperature of the environment, increasing day by day due to heavy vapor compression systems used to meet the cooling load of buildings. The huge electricity is required for handling the cooling demands which are further destroying our natural resources. Efforts can be made to look for sustainable cooling system instead of using costly air conditioning systems. In this study effort is made to look for a low cost air cooling system for buildings by use of thermal energy of soil. The geothermal effect of soil can be very helpful for decreasing or increasing the temperature of the air. Using this method of cooling, the high grade energy demand, as well as environmental issues, can be minimized. The best use of geothermal energy can be made effective with the use of Earth Air Heat Exchanger method. The study of the air velocity may help in finding a maximum temperature drop of the air. With the rise in velocity to appropriate value it gives better results at a velocity of 2.5 m/s the maximum drop in temperature is 7.2 °C, for 3.4 m/s maximum drop is 6.5°C and at a velocity of 4.8 m/s drop is 4.0°C. Therefore the velocity of 2.5 m/s is cost effective and result oriented to a given Earth Air Heat Exchanger. The maximum average fall for a velocity of 2.5 m/s is equal to 5.4°C in the month of July for hot- humid climate.
