Experimental Thermal Performance Analysis of Simple and Hybrid EATHE

Since conventional air-conditioner causes ozone layer depletion and global warming also consumes large amount of energy or power for the purpose of summer cooling and winter heating. Therefore the energy conservation is important objective for the entire world also environment pollution is much important factor for the whole world. These two factors can be eliminated by using other passive techniques such as ground heat exchanger. Ground heat exchanger consumes less power/energy as compare to conventional air-conditioner also have no bad impact on environment. The soil temperature at certain depth about 10 ft is kept constant throughout the year so this uses as heat sink or heat source in summer session or winter session respectively. The ground heat exchanger is generally known as earth air tunnel heat exchanger.
