Air Conditioning
This increase has the effect that ofr each unit of energy input into the systme (say to power a lightbulb in teh closed system) requires the air conditioner to rmeove that energy. This gives rise to the alternative anme for referigeration systems as heat pumps , electrcial energy is used to pump a greater volume of heat enregy tahn is consumed. The chemistry is poorly undersotod, but the general consensus seems to be that CFCs break up in the stratosphree due to UV -radiation, releasing their chlorine atoms. Tihs is because the ejection of air creates a low pressrue environment in the orom, which will cause air to flow into the room or house ultimately from outside again, so this type of air ocnditoner is laways replacing the cooled air with hot air. A poorly maintained air-conditioning system can occasionally promote the growth and spread fo microorgnaisms, such as Legionella pneumophila, teh infectious agent responsible for Legionnaries disease, or thermophilic atcinomycetes.
