Portable AC Reversal Adapter

thingiverse

I'm really frustrated with my portable air conditioner. It literally sucks, as they all do. The problem is that it takes in warm air at room temperature, blows out a portion of it back into the room, cooler, while sending the hotter part outside through a hose attached to a special panel in the window. However, this leaves you with negative pressure. Something has to replace the air that was blown out the window, and warm air seeps in under doors and through cracks everywhere. When I'm trying to keep my room cool as a sanctuary from the scorching heat of the California Central Valley, any air coming back in is much warmer than the cool room I'm trying to maintain. It's really hopeless! This machine can only cool about half the room at best. What if we could turn things around? What if the air conditioner sat outside and transformed hot air into even hotter air outdoors while sending a stream of cool air through a hose indoors? Now you'd have positive pressure, and the oldest, warmest air in the room would be squeezed out the cracks while cool air permeates the room. But no, we won't sell you one of those units. You might trip over the outdoor extension cord and kill yourself and sue us! So I decided to take matters into my own hands and made this adapter myself. On one end, it snaps into the hose as it would have snapped into the back of the air conditioner. The other end fits neatly over the curved vent where the cold air comes out – held in place with duct tape (used for its original purpose!). Now the hose is carrying cool air, in through the same window opening where it used to carry hot air out. This particular adapter fits an Idylis 0625615 and would likely fit most Idylis models with minor adjustments to the vent fitting. I printed this adapter using a FlashForge Creator Pro printer with the following settings: no rafts, supports enabled, and a resolution of 0.3 mm. When printing in ABS, I found that maintaining adhesion was a challenge due to the summer heat causing PLA to soften and deform. To overcome this issue, I printed the part with a few millimeters of support height where the hose slides into the connector. However, be sure not to generate support inside the connector – it'll be impossible to remove cleanly! Depending on your printing program, you may need to manually adjust the support. After printing, remove the "ears" and brim from the part, then cut off the thin partial ring that completes the circle on the bottom. This will allow the hose to slide and snap into the connector.
