Heat Wave Special - Can I make a Window AC work as a Portable? 

Excellent demonstration!.....Two years ago, I bought a "modern" inverter portable a/c (even had a heat pump). It also had an intake as well as an exhaust hose. The problem with this unit was, that on a super hot day, the exhaust hose would heat up the room thereby degrading the performance. Needless to say, back to Home Depot it went. I eventually went with a Midea 12k btu "inverter" window unit with heat pump (model # MAW12HV1CWT, this is NOT the U-shape unit). Could not be happier.

Some people are wild crafty! That was just cool to watch!

Turn the concept around. Throw the AC unit outside, and duct IN the cold air. That way the compressor can run freely, and you don't have to hear the roaring unit next to you.

This is totally brilliant and Inspiring , Thank you !!!!

What if u add a booster fan they use for hvac system on the exhaust hose or on both would it still be straining the compressor or if it’s does work how’s the efficiency don’t think them booster fans pull to much amps regardless old ac units are tanks compared to newer ones

Really enjoyed your video is a very clever idea you got there on that. With that being a thru wall ac with way the exhaust air flows through then out condenser instead of the fan right behind it. I have not seen a ac like that. You are right on having the bigger size hoses that would of helped, but I have an idea you can try if not too late to take care of that. They make in line exhaust fans in a 6 inch size that normally are put on furnace and boiler vent pipes that you could put on your inlet hose to blow more air into the unit or put on the exhaust side to pull more air out. That would help the fan in the ac as it was not designed to have the extra restriction from the hoses. The fan is around 25 bucks though an are 120v. I hope you make it through the 2 weeks before you get your central air ok. Being hot and trying to sleep doesnt work too well. Thanks for the cool evening. Oh yeah forgot to ask you what was you going to do about the condensate from the evaporator coil?

Listening to you and the fantastic comments , I am inspired to think and do ,like this! Wow ~ exciting ! :-)

What about the condensate? My window unit was peeing nearly constantly last weekend.

Maybe room air instead of using outside air on the intake line? Can that work?

The problem with this is that it would need additional insulation on the tubes and on the wooden enclosure which further raises complexity.

Stay cool, man. Stay. Cool.

Nice vintage Westinghouse. That's circa 1969

Genius!

Interesting stuff. Could you mount the horizontal ac vertically?

Curiously when I open replies to comments (including my own) they are blank.....

I took my horizontal window unit and installed a bar across the top and then put foam for the rest of the vertical

I love how 26°C is a heatwave for him but we use air conditioners set to 24°C where I live.

Why not an in-line duct fan helping to expel (suck the outlet air) back outside, in turn aiding in condenser temp and overall efficiency?

The SEER rating on that dinosaur must be coprolitic.

I know now that with central HVAC this is now moot, but there were no case window AC units available? As you probably know, window AC units are terribly inefficient.

Since you can't get a larger hose, why not consider using two 6" outlets instead?

Experimentally I found I needed to pull 300 CFM of air with a six inch hose per 5000 BTU's to get the same temperature as not enclosed. 200 CFM gave a 30 degree F differential instead of 20 degree F.

Hold on to that air conditioner. Those old units will out live generations of modern junk. Those old reciprocating compressors are so much more robust and preform much better as well.

I cam here for AC but I seen your old old cash register it blow my mind.. would you like to sell your old cash register?

WHY HAVEN'T YOU PUT A SMALL FAN INSIDE THE EXHAUST TUBE OR AT THE END OF THE TUBE TOO ACTUALLY PULL THE AIR NOW YOU HAVE A PUSHER AND A PULLER

Why not put it outside and just pipe cold air in

I wonder if anyone has tried to chop a window unit in half and extend the refrigeration lines / wiring to turn it into a ghetto mini split.

Good day.

26.3C....heatwave?

Thats just making a less efficient window ac unit
