It turned into "Big Business". He has a manager handling the sales and tech 

support. So as is the case with any "Big Business", red tape and lots of 

middle men.

Did you get more details??? Did I divulge trade secrets?  



Ernie



Hey, I may fly out to Colorado Springs in Oct for the Bonanza

Convention, maybe we could hook up then.

I mentioned the same possibility of using this  window unit in my Mustang II experimental. I'm no electrical engineer so don't  quote me on this as I probably have it all backwards, but something about the  amps that unit pulls is at the AC 110volt setting. It would supposedly pull more  like 60 amps DC? Your L-29's may easily handle this, but that's pushing most DC  alternators...

Not at all. You need to just use OHM's law and convert to power, 4.5

amps (at) 110v = 495 watts, P=E x I ...conversly I = P/E so 495 watts

divided by 24v = 20 amps at 24V. For startup current just double that

value and that ups the startup current requirement to 40 amps, add 10%

for Inverter inefficiency and you're in the neighborhood of 50 amps

for startup, and about 25 amps while running. The inverter I saw for

$100 was rated at 900 watts continuous with 1800 watts peak, more than

enough for this application. I've never seen these tiny window units

before, thats why I never considered using window units, but the

weight and current draw of these little babies makes them viable.



Also remember that the alternator need not be able to keep up with the

momentary startup current requirements, since the battery will act as

you current storage tank, the alternator just replenishes the current

during continuous use. Even a 30 amp alternator would  be able to

supply 5 amps of charging current during continuous AC use, but I

wouldnt recommend doing this with anything under a 50 amp alternator.

Ernie, I recently bought one of these units when my  heat pump at home failed. If memory serves the box advertised it weighed 40  pounds. It may come in at less than that once you strip it of it's current  chassis, and reconfigure to fit into the L-29. All food for thought huh?

Reviewing some of the conversations we had on the Mustang site on this  topic, another consideration that was brought up a couple times is possible  interference between an inverter and the avionics....On a positive note, it  could be run on the ground from a normal 110 plug in. Get the plane cooled down  without draining the battery!

I think the inverter numbers are a bit off. here is the formula for power

invertes. This is for a 24v to 110/120 inverter

Here's the formula for all power inverter: Amps (needed) x (volts)110 V AC =

wattage of inverter needed



50amps needed for start X 110v =5500 watt inverter. I have a 1000 watt

inverter and it does not run much let alone a small AC unit. The inverter

needs a lot of air(on the ground is the only time this would be an issue) or

it will overheat and trip fast.



sure would be nice to have it though. I would also go as far as to put a

small boat type halon system in the nose if that was the place I vould run

have the compressor. Again big heat producer and they are not ment for

closed spaces. just my 2 cents.

Hi Ernie,

  

 Sorry about the delay getting back to you.  The full time flying job  is the one that pays the bills and I've been busy with United.  Then  got side tracked with getting checked out in a L-39, which solves the AC problem  as long as I don't go back and fly my L-29.  LOL>

  

 I'll email you directly.

  

 Thanks.

Sounds like we could just cut open the canopy and silicone in a home window  mount AC unit and strap it down.  That should work for until you get  airborne... LOL

scott, e-mail me  directly with info as well please. bcolombo(at)twcny.rr.com (bcolombo(at)twcny.rr.com), Still need a  tach/gen and tach if you know of anyone who might have  a used  one.

Hi Bill,

  

 Speaking of Red Tape, you coming to Reno Air Races.  I most likely  will be doing an engine change on my L-29 and any extra bureaucracy "help" would  be welcomed.

I had a nose gear problem in my L-29 this weekend. A problem all of us can have due to a design flaw.  Simple fix though.  Will type up what happened and post it here and the CJAA web site tomorrow morning. (with photos) At work now and not enough time to type it up.....All ended up well though when I hit the mains down hard and got the nose wheel to lock before setting it down....

I heard it was pilot error!  Or several errors..  LOL

The AC unit I bought from Walmart is a Goldstar. I gave it a hard  break in, running it wide open for 4 days until I made a decision which heat  pump to install. Never missed a beat. I paid $86 I  believe.
