Experimental Study of Bank Type Earth Air Heat Exchanger for both summer and Winter Seasons

Abstract

newline Non-renewable energy sources are depleting as high-grade energy consumption newlineincreases in heating, ventilating, and air conditioning systems used in the building sector. The newlineair conditioning systems are expected to be more than double the capacity of the currently newlineinstalled systems by the year 2050. Looking for alternative systems which consume very newlinelittle energy and do not emit harmful emissions is the need of the hour. One such system is newlinethe use of geothermal energy, and this energy is considered clean, sustainable, eco-friendly, newlinecheap, and readily available irrespective of other forms of energy availability across the newlineglobe. In this system, water or air may be passed through the pipes buried deep underground, newlineand it will come out at a lower temperature in summer and higher temperature in winter than newlineambient temperature. This pre-cooling or preheating of ambient air helps reduce energy newlineconsumption, estimated at 20 % of global electrical energy consumption. There is hardly newlineany harmful impact on the environment as no emissions are there, and electricity newlineconsumption is also reduced to the extent of the running of the blower. The principle of using newlineground inertia dates back to very old times when people used to flow air through the caves to newlinemake it cooler or warmer in extreme climates
