In present scenario, Heating Ventilation, and Air Conditioning system (commonly used in the air conditioners) is very efficient and reliable but it has some demerits. It has beenobserved during the last two decades that the O3 layer is slowly destroyed because of the refrigerant (Chlorofluorocarbon and Hydro fluorocarbon) used for the refrigeration and air conditioning purposes. The common refrigerant used is Hydro fluorocarbon’s which are leakedand slowly ascend into the atmosphere. When they reach to O3 layer they act on O3 moleculesand the layerQ ofO3 is destroyed. A single molecule of Hydro fluorocarbon can destroy thousands of O3 molecules and that's why it has created a threat for the not only to maintain earth eco system stable but also toexistence of earth. Even the percentage of Hydro fluorocarbons are emitted into the atmosphere compared to CO2 is negligible but its global warming effect is few thousand times of CO2. The effect of 100 gm of HFC can destroy 0.5 tons of O3 molecules. These Hydro fluorocarbons once destroy O3 layer; it takes hundreds of years to recover its thickness as it is formed by complex reactions. This is because as Hydro fluorocarbons comes in environment, they remain in atmosphere for 18 years. The capacity ofHydro fluorocarbons to increase in earth temperature 10% is contributed by Hydro flurocarbon’s only. That leads to the emergence of finding an alternative of the conventional Heating Ventilation, and Air Conditioning system, i.e. thermo-electric cooling and heating system. Thermoelectric cooler controllers are used for thermoelectric cooling and heating in combination with Peltier elements or resistive heaters. Peltier elements are heat pumps which transfer heat 2 ,) from one side to the other, depending on the direction of the electrical current.
