Electrolux Air Conditioner Dual hose Roller Shutter Sealing
Description
**Portable Air Conditioners** are great but come with two major issues. First, they **usually come with a single hose**, so they waste energy by rejecting cool air outside. Second, they may be **hard to seal properly**, that is, connecting the ducts to the outside while preventing hot air from entering, further wasting energy. **This project aims at mitigating both issues.** **The project includes:** - **Dual hose conversion**, using a [custom-made backplate](https://www.thingiverse.com/thing:6745319) and an extra [hose connector](https://www.thingiverse.com/thing:4519730) - **Sealing** using the shutter rail, a plastic board and [seal connectors](https://www.thingiverse.com/thing:6745481) with nets. - **Caches**, [custom-made](https://www.thingiverse.com/thing:6745373), reducing light entering the room when not in use. _Below are instructions for making the project._ **Dual hose conversion:** - Print or build an appropriate backplate for dual hose conversion. I'd suggest looking at [thing:4519681](https://www.thingiverse.com/thing:4519681), [thing:5421906](https://www.thingiverse.com/thing:5421906) or [thing:6745319](https://www.thingiverse.com/thing:6745319) depending on your A/C model and/or printer build area (custom plate model included here for convenience). - Print or purchase 3 additional hoses. I'd suggest printing 2 PLA hoses for inlet using [thing:4519730](https://www.thingiverse.com/thing:4519730) (model included here for convenience) and printing an additional PETG one for completing outlet. Alternatively, you can purchase outlet connectors directly from Electrolux, part number [#4055413712](https://shop.electrolux.fr/c/bride-sortie-d-air-anneau-interieur-ptb-u/p/4055413712) (French, non-affilated link) - Purchase an additional 15cm * 1.5m hose, Electrolux part number [#4055349213](https://shop.electrolux.fr/petit-electromenager/climatiseurs-et-purificateurs-d-air/tuyaux/tuyau-de-climatiseur/p/4055349213) (French, non-affilated link) or your local store, Amazon, AliExpress, etc. _In single hose setup, you'll still need one additional connector for outlet hose._ **Making seal kit:** - Make or purchase a **plastic board of correct thickness** for your shutter rail, cutting it wide enough for inserting in the rail without too much effort while still sealing correctly. - **Pierce holes of adequate diameter** for adding [seal connectors](https://www.thingiverse.com/thing:6745481). - **Assemble seal connectors**. They are made of 3 parts: A connector, nut and ring. I've included the models here for convenience. I'd highly recommend adding a mosquito net to prevent insects or big particles from being sucked inside the air conditioner... or just entering the room when no hose is connected. - **Add adhesive bottom seal strip**. This the same adhesive strip you can put on garage doors for better sealing. _In single hose setup, pierce only one hole and install only one connector._ **Install your new seal kit and profit!**
