We are being advised to buy such a self-condensing cooler since it doesn't require any exhaust/connection to drain the heat when cooling our room.
I find this a bit funny since i always thought that any cooling equipment that cools down your room will inherently heat up the temperature of some air somewhere else (i.e. at the back of the cooler, outside if you put an exhaust pipe, etc).
Somehow this does not seem to be the case here, or am i missing something? How does it work?
(ps: no, a regular aircon is not an option for us)
