5. Effect of Air Conditioning on Global Warming and Human Health

With rapid growth of industrialization, deforestation and cleaning of land over a last few decades causes a considerably rise in temperature of environment and due to this air conditioning becomes a basic need to achieve a thermal comfort for people. However, in accompanying this thermal comfort it also causes an adverse effect on human health and also increases the risk of global warming. The regular or prolonged use of air conditioning results into dry skin, illness and constant fatigue, breathing problem and also the central air conditioning units causes indoor air contamination which results into cardiovascular diseases. Air conditioning also have a bad impact on global warming, after the Montreal Protocol in 1987 the HFCs replaced CFCs and HCFCs in lieu of the protection of ozone layer but HFCs are having high global warming potentials causes global warming. Due to the anthropogenic activities greenhouse gas emissions and their concentrations are rapidly increasing. Therefore it is necessary to find out the replacement of HFCs to reduce the global warming. Thus chapter explain the effect of air conditioning on global warming and human health and also their remedies.
