Comment on I've been using this simple trick to keep cool in the heat wave (UK)

  Which is why most people cant get one of these because their landlords are shitheads.

    They make portable minisplits now.

      Or just portable, single unit ACs. I got one of those recently.

      It blasts hot air through a duct that hopefully you’re able to direct outside while preventing outside air from getting in. Also noisy as heck, since the full unit is inside the house, and not as efficient as split units, but they do work…

        while preventing outside air from getting in

        If that worked you’d slowly turn your dwelling into a vacuum chamber :-)

        The same volume of air will enter your home in one way or the other, the important bit is that it’s cooler than the exhausted air. In particular you don’t want the hot exhaust to recirculate back in.

        Ideally you’d get medium warm air from another room into yours, and warm outside air into an unoccupied room.

        Yeah those are much more common and way cheaper, but also much less efficient.

        Portables are hot garbage. Get a proper air source wall split. Cheap and immensly cheaper as a heat source that anything you use right now.

        Yeah with the current heatwave that’s to be expected. Just get one during fall or winter, and be ready for the next year.

      As far as I know they are mosty designed for vertically sliding windows, uncommon in Europe. For american style sliding windows a think they are brilliant.

        That’s not really a portable AC, or even a minisplit. I am talking about a portable AC with two parts (thus called a split unit), one for the outside that dumps the heat, and one on the inside blowing cool air. They are connected with flexible pipes.

  Protip: condensers function better when its cooler. You can save money by putting the condenser in the neighboring, air-conditioned apartments.

    Yes, ac is a heat pump that can only work in one direction of cooling.

      Not necessarily, a lot can reverse and pump the heat inside
