    For the engineers on this site

    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)

    Looks like that unit you linked has an exhaust pipe for the a/c mode.

    If you dont want to use this then you should get a split type ac and leave the condenser outside, they should be able to pipe the pipping through the walls.

    that's exactly what i was thinking to do, but then this model above was suggested: 50% more expensive since "you don't need this pipe/exhaust"...

    yeah i saw that but it's not clear you must use it to cool. at least that's not how i read it in the english text

    Maybe it breaks the laws of thermodynamics then

    If you use AC mode then you have to use the HOSE to get rid of the hot exhaust, there is NO AC unit that doesnt have hot air coming out the back.

    The manual you linked would appear to indicate that you have to attach the hose to a window or similar to allow it to vent.
