Black & Decker Portable Air Conditioner BPACT14WT: Single to Dual Vent Conversion

If the air coming from the condenser is hot, you might have too much restriction / too much pressure loss in your ducts, DIY adapters etc combined. That in turn increases the power consumption and at the same time decreases cooling. Try to at least have the hoses as short and straight as possible and with gradual turns instead of sharp kinks. Hope this helps, and thank you for the video!

Actually I do like the fact that your machine gets noticibly quieter with the mods than be4, I have a portable ac unit too with a massive 6 inch single hose and I am still trying to find a way to modify it, because aside the room negative pressure issue with these single hose units another thing is the noise it makes. Mine has a large condenser vent behind it with a very powerful and noisy blower fan. The compressor also makes a lot of noise through the condenser vent. Thanks for a great video, very educative too👍

Best and very explanatory vid out there !   Thank you for making, explaning it all very detailed and offcourse for sharing. Best of all, from the Netherlands. 👋

Pretty cool! Thanks for the video

Great video - I am doing this now with some experimenting with intake to my ductwork to the basement. Two things I did that changes everything. 1. Insulate the exhaust pipe. 2. Vent through the wall so the exhaust pipe would be 12 inches (and insulated). AC comes with a nice adaptor and cover for the wall for the winter. Looks better as well. Made my comment before watching the whole video... you can get form fitting insulation for the exhaust - it is not crazy and makes a big difference. If you look at the adaptor for the GE model to convert 1 to 2 hose, it has vents so it is not 100% sealed as yours is... something to think about.

Thank you!! I am doing this STAT.. unintended consequence of this drawing air from the room is is also causes a vacuum - and in my case it is sucking disgusting cigarette smoke from the surrounding units into mine. I’m hopeful that this should alleviate this somewhat.

This is super helpful, thank you and much appreciation for making this video. I Plan to convert my Honeywell MN-10CES single hose to dual hose, and it's similarly set up as your B+D unit on the air intake. Question, have you noticed any issues with taking the air intake from the larger space down to the hose 5.9 space for air intake, and is the unit still working fairly well using this modification?

Do you have a video on how to set this unit up for using the heat for winter months?

increase effeciency even more by shortening the exhaust tube to your window so less heat evaporates back into the room. And you can buy a hose sleeve that insulate sthe hot exhaust hose they work really good a well

what i did was i covered 2/4 of the vent with foil, 1/4 of the vent was uncovered, 1/4 was an hose from my old ac, I have a Logik glp09-port . means i got a 9k btu heat pump, its quiet, the compressor is insulated to reduce noise, its self evaporative, it think it has a built in reversing valve in the compressor. so it actually really really helped with the pressure problems and improved cooling! you dont actually want maximum suction, unless the hose is bigger than the exhaust hose, always have an opened hole so indoor air will contribute. ill covered the opening with foil en see

i wished you would have made the video doing the whole process! it would have been really cool

Question I know it would make the unit quieter. But recircling the air from the inside. Would or would not cool faster? I believe it would.

My unit is frigdaire chill flex pro 12K btu. Single hose SUCKs. I had a 3d printed the second hose mod. I will try it soon Some use the water drain to cool the condenser

Do you seal the intake hose your adding completely around the intake vent ? Or do you seal the hose around the vent with two little slits to let some inside air in ?

Hello, another question for you, I’ve got two portable a/c units, plan to use them side by side in the living room to cool an 850 sq foot condo. Do you feel the two units can operate together a few feet apart, so if one unit fails to keep up with higher temps, the other unit would kick in, versus the 2nd unit never kicking in, where the first unit is doing all the work? I supposed I could extend the hoses and have them about 10 feet apart. What are your thoughts?

Confused as to how this might work if your unit only has a single fan. Are there two intake fans inside the unit? One intake for the compressor vent, and another intake for recirculating the inside air? It's these two air streams you mention are sealed off from eachother, right? I'm wondering what drives the airflow over the cool side if the air intake for the compressor comes from outside, over the compressor to cool it down, and then right back outside. There must be some other fan for the evaporator side as well, right? Or do they use some kind of clever engineering with a single fan to draw air in through both intakes while preventing them from mixing together?

I'd like to try this with my Danby. No worries about a fire hazard or anything?

How's it holding up. Thinking of doing this with mine.

How did you establish the unit was sealed top to bottom on the inside of the case?

I thought that would only dehumidify the out side air after doing this. But what do I know.
