Portable AC Reversal Adapter by Joymaker

Last crawled date: 3 years ago

My portable air conditioner sucks. Quite literally. As they all do.
Here's the problem: it takes in air at room temperature. Part of it it blows out back into the room, cooler. The other part is sent out a hose, hotter, out a special panel in the window to the outdoors. But what does that give you? NEGATIVE PRESSURE. Something has to replace the air that was blown out the window. Air is sucked in under doors and through cracks everywhere. And when I'm keeping my room as the one cool sanctuary in a toasty warm house amid the scorching heat of the California Central Valley, whatever air comes seeping back in is a good deal warmer than the cool room I'm trying to maintain. It's hopeless! This machine cannot keep more than half the room cool, at best.
What if you could turn it around? What if the air conditioner sat outside the house and transformed hot air into hotter air outdoors, while sending a stream of cool air through a hose indoors. Now you have POSITIVE PRESSURE and the oldest, warmest air in the room is being squeezed out the cracks while cool air permeates the room.
But no, we won't sell you one of those. You might trip over the outdoor extension cord and kill yourself and sue us!
So I did it myself. I made this adapter. On one end the hose snaps into it, as it would have snapped into the back of the air conditioner. On the other end it fits neatly over the gently curved vent where the cold air comes out – held in place with duct tape (put to its original, intended use!) So the hose is carrying cold air, in through the same window opening where it used to carry hot air out.
This particular adapter fits an Idylis 0625615 and would probably fit most Idylis models with minor adjustments to the vent fitting.
