Yes, an air conditioner takes the warm air from inside a room and transfers it outside.
An AC unit takes the warm air from inside a room and transfers it outside. It also consumes electricity which generates further heat.
A Japanese scientist found in 2007 that air conditioners in Tokyo raised the temperature in the city by about 1°C. Surprisingly, the heating effect was more at night than during the day when more air conditioners were used.
This is because the planetary-boundary layer, the part of the atmosphere touching Earth’s surface, is thickest during the day. The extra heat produced by ACS disperses upwards. At night, the same layer reduces from a thickness of 3 km to less than 100 metres! So the heat remains closer to the Earth’s surface.
Researchers feel the excess heat could be channelled through the city’s waste water pipes, since water can dissipate four times as much heat energy as air. This would reduce the heat on the street.
