They give off a lot of heat into the atmosphere, and for some of you may understand the heat island effect in cities, where the urban areas are much more warm than the adjacent rural areas, but we also have problems that, when we lose power, we can't open a window here, and so the buildings are uninhabitable and have to be made vacant until that air conditioning system can start up again.
Prenose mnogo topline u atmosferu, i neki od vas vjerojatno razumiju efekt toplinskog otoka u gradovima, gdje su urbana područja mnogo toplija nego okolna ruralna područja, ali također postoje problemi da, kad nestane struje, ne možemo otvoriti prozor pa zgrade postaju nenaseljive i mora ih se napustiti dok se opet ne pokrene klimatizacijski sustav.
