    Portable Air Con Unit 8th Nov 18 at 2:47 PM
    Did a search but nothing in the last 4 years..
    After the hot summer of 2018, I thought now would be the best time to buy an AC unit.
    Looking for any advice/recommendations from anyone who has one.
    It would need to cool a room of approx 4.5m x 3m.
    Looking ideally for a quietish one as this is for a bedroom.
    Do modern ones all need an outlet pipe to outside?
    I know there are some more energy efficient than others.

    Any help gratefully received !!!!

    I saw portable units in a shop last summer that (apart from the mains electricity lead) had no connection to the outside. Just how they work, I don’t know as the laws of physics dictate that the heat has to go somewhere! (The only options I could think off is that it works by evaporating a tank of water, or has a peltier which heats an insulated heat-sink).
