minus-squareEndlessNightmare@reddthat.comlinkfedilinkarrow-up2·3 days agoDual-hose portable ACs avoid the vacuum problem. You just need to have good sealing around the intake and exhaust hoses.
minus-squareKazumara@discuss.tchncs.delinkfedilinkarrow-up3·3 days agoOh I haven’t seen one of those yet, that does sound like an improvement.
minus-squarestarik@lemmy.todaylinkfedilinkarrow-up1·2 days agoSo it creates positive pressure in the house?
minus-squareEndlessNightmare@reddthat.comlinkfedilinkarrow-up1·2 days agoThe air that is brought in from outside via the intake hose is the same air that is heated and then ejected through the exhaust hose. In theory, it shouldn’t cause a change in pressure.
minus-squarestarik@lemmy.todaylinkfedilinkarrow-up1·edit-22 days agoSo there is a separate intake and output inside the house for the cold air?
minus-squareEndlessNightmare@reddthat.comlinkfedilinkarrow-up1·2 days agoOutside air. If you are using AC, the intake probably isn’t cold. But: air in => heated up by the AC => sent out. 2 hoses in the window that connect to the back of the AC unit.
minus-squarestarik@lemmy.todaylinkfedilinkarrow-up1·1 day agoIf it’s blowing cold air into the house, there has to be an equivalent volume of air leaving the house.
minus-squareEndlessNightmare@reddthat.comlinkfedilinkarrow-up1·edit-21 day agoAir from room is cooled and that same air is blown back into the room after being cooled. Air from outside is pulled into AC (does not go into room), gets the heat from the air in the room, then is blown out as exhaust. If you aren’t sure, look for a diagram or in-depth explanation.

Outside air. If you are using AC, the intake probably isn’t cold. But: air in => heated up by the AC => sent out.
