For a mere 195,000.- CHF you can buy affordable housing. Cannot believe that such an amazing deal exists.

There is so much nature in this property, you will be literally sleeping with one foot outside.

However if you want to install AC, sadly the commune won't allow it as it does not fit the theme of the location.

I think this is a start to solving the housing crisis in Switzerland, good job Geneva for setting the example👌🎉

Just sharing this since today will be the hottest day..

If you have a portable AC with single hose flow and it is struggling to keep your room cool please consider a simple upgrade to dual flow.

Normal ACs have a cooling unit on the outside and is isolated from the inside. The cooling unit cools thick copper wires connected to your internal unit.

Your internal unit only blows inside air over coils on the internal side, so you feel cold air coming out. There is no air exchange between outside and inside, only heat from inside is transferred outside via heat conducting pipes to a cooling unit.

Unlike a standard window unit or a split system, a single-hose portable AC sits entirely inside your room.To work, it pulls in the air from the room you are trying to cool.

A single hose AC uses some of this air to blow cold air back at you, but it uses the rest of that air to cool down its own hot internal compressor.

It then takes that newly heated air and exhausts it out the window through that single hose.

By constantly pumping air out of your room, you run into a major physics problem: negative air pressure.

When your AC blows air out the window, it empties your room a little bit. Think of it like sucking on a juice box.

Instead of crumpling like the box, your room sucks hot outside air through the cracks in your doors and windows to fill the empty space. This means your AC is just pulling hot summer air right back into the house while throwing your nice, cooled air outside.

A dual-hose unit completely separates the air it uses to cool its motor from the air it uses to cool your room:

Hose 1 (Intake): Pulls hot air from outside just to cool the internal compressor.

Hose 2 (Exhaust): Blows that now-superheated outside air right back outside.

Because it uses outdoor air to cool its machinery, the air inside your room is just continuously looped over the cooling coils. No air is pumped out of the house, no negative pressure is created, and no hot outdoor air is sucked inside. Your room gets cooler, faster, and the unit uses significantly less energy to keep it that way.

You can fix this easily by adding a second hose so the AC pulls in outside air instead of your room's air.

Materials You Will Need:

A new hose-Buy a flexible plastic or aluminum air pipe from a hardware store. You need a hose that is about 2 meters long (if you can only find 1-meter pipes, buy two and tape them together). Make sure it is roughly the same width as the exhaust pipe.

Cardboard

Scissors

Strong Tape (like duct tape)

Instructions:

Find the intake: Look at the back of your AC to find the vent that sucks air in to cool the motor. This is usually located near the bottom of the unit.

Make a cover: Cut a piece of cardboard so it completely covers that bottom intake vent. A box shaped cover works well enough.

Make a hole: Cut a hole in the middle of your cardboard cover exactly the size of your new hose.

Tape it together: Tape the new hose securely into the cardboard hole.

Attach to the AC: Tape the cardboard cover directly over the bottom intake vent. Make sure to tape the edges well so no room air can sneak in!

Put it outside: Stick the other end of your new hose out the window, right next to your original exhaust hose.

Now your AC breathes outside air to cool itself and does not suck hot air from outside in.
