What keeps you cool? In Singapore the day time temperature is around 30-32 Celcius. During the night it drops to around 25-27 Celcius.
What keeps people in Singapore cool? Air conditioning. I love it at around 24 Celcius.
Here's a picture of the compressor unit that is outdoor. This of course is a commercial unit which cool a building.
In fact I am now in the comfort of an air condition room posting this picture up. Do you love air conditioning?
