Lost Dutchman State Park.

Last minute, let's do it trip.

Lost Dutchman Butterfly Wonderland May 5 11 16 by dondq | Photobucket

Warm this time of year, while camping it was 102ish during the day. the 8000 (portable) and 5000 (through the wall) btu ACs worked very well. The temp. gun showed 126 on the sunny side window glass but the int. stayed under 90 all day. All systems functioned well.

Only less than 250 miles r/t. Our new mascot, Mr. Bill, had a great time.

Left Wed., home today.

Next trip the 27th to the 30th to Dead Horse State Park in Cottonwood AZ. This is our (Zuks of AZ) annual Zookapalooza off road event.

Sorry Nat, even at 102f, we didn't "fry like an egg".

impressive that 14000 BTU of A/C kept you down 15 degrees or so in the sun all day... makes me wnder if I am overkilling it by iinstalling 50,000 in a short 7 row bus...

but then mine is for driving so I have engine heat to overcome..

Plus the front door was open all the time during the day.

I love to drive my car with the windows open and the A/C on.. sound like i can do the same in my bus and still be cool! or you guys did an incredible job of insulating your bus!

I thought the reason you were going with the 50K AC was because you decided not to insulate and because you like to drive with the windows open? If 50K turns out to be to much, you can always hire out as a meat locker during hunting season.

I've been curious to know if you've ever looked at the AC units on government surplus?

I didnt look at A/C units on govdeals real close.. everything seemed like a lot of parts.. plus I wanted new ones.. with A/C its critical that you build a matched system and not just throw a bunch of parts together..

yeah I went with 50k figuring I could also get decent cooling with the engine at a slower idle too.. my compressor is rated at sustained max RPM of 5000.. something it will never see on a diesel bus.. the data sheet also mentions it gets its maximum output at 2500-3000 RPM.. (note thats COMPRESSOR RPM.. not engine RPM.. i wanted excess capacity so I can idle down to normal slow idle and still spin it fast enough to work..

it is being overdriven somewhere around 1.4 from my meager calculations.

the new modern sanden compressors ramp up on capacity quite quickly from their minimum rated RPM. so even if idling my bus at 600 RPM I can easily see 60% plus capacity at slow idle.. and at a fast idle of say 1000 im up to close to 80%..

im using TxV valves which will reduce the capacity of the system based on load.. I think the unit itself has a 3 speed resistor for the fan.. which im building a Variable speed drive for it... so I can slow the fan way down if needbe.. I can also cycle the compressor if needbe..

The ones I've seen are complete matched kits but they often do a pretty poor job of listing the particulars. I'm seeing two kinds. One is a large basket of parts. The other is an environmental control unit in a box, also new and selling cheap. I wish I had a basement to put one of those into. I'll send you a link sometime when I find a good example.
