Exhausting refridgerator heat

[fortyniner]

This DC unit specs 40Watts.  45% run time with 86deg ambient . I like the fact it runs directly from 12 or 24 volts eliminating the inverter losses. A bit pricey but seems quite efficient. At that power level a small computer muffin fan might exhaust enough air to reduce interior heat contribution.

Ed, here is a pic of my house in case you can't open the HGTV link. (It's probably 6 years old) The link had the video they did of my home and a little of what I do.


Back to the regulary scheduled thread.[/i] 

I almost hate to admit this guys but I'm guessing my frige is not installed correctly. (go figure)
They have it enclosed in a cabinet/box and do not have any outside access to air. The only entrance/exit from that "box" is around the edge of the front of the frige and they drilled about 10 or so, approx. 1.5 inch holes on the top of the "box" at the back wall. That is where the heat - and lots of it - comes out. When I got the bus, there was a LOT of yellowish residue in the back of the frige, mainly on the floor. It was my understanding that that was from the use of the propane which was not vented to the outside. (I know, I know....)
By the way, altho I know it works, I do not even have the propane hooked up to it.

So anyway... I will be moving my frige to the other side of the bus soon but it may be a couple months before I get a different frige. Money, ya know. But I will make provisions for whatever the next one will be when I do the move.

I'll check that one out Tom. Effeciency means a lot to me! Thanx!  But also,  to a point.  I like the "good stuff", so I save for it till I can get it, or my patience runs out. 

Thanx again guys......

Our fridge is a small 16 CF household type, I mounted the microwave on top of it with angle brackets and included a thermostatically controled fan behind the microwave that vents thru some closeable louvers on each side of the microwave, the air enters at the bottom of the fridge in the front and side and exits thru the louvers at the top, it's enclosed on both sides and the fan has never come on so the air currents must be enough to cool it, it's set to fire up the fan at 110F.

Chaz! You are one talented individual!  Great house!  The designs are amazing!   I love working on this stuff.........working and creating are two different things.......!   You create, I work!   LOL!

[Chaz]

Thanx Cody!!!!!!!!!!!! I just had a revelation after reading your post!!   Seriously!!!!

I too, want to mount my mico on the frige AND, I am planning on mounting the flat screen on the "wall" that I build for the frige. All three heat producers will be in the same area. (someone mentioned earlier that the TV produces a lot.) So "maybe", with a little figuring, I could vent all three via a simple - but quality non-leaking - vent out the top. And then be able to close it to hold what little heat they produce in the winter.

Hmmmmmmmmmmmmmmmm, veeeeeeeerrry intresting!

Thanx Pat. (We were typing at the same time.)

Chaz, great looking place......what i can see of it.    Tried the HGTV link about a dozen times again with the same result, just a black screen.  Lin, i have FireFox, still didn't get anything.   Was able to see all of the other links though.  I first became aware/interested in underground homes back in the late 70's, early 80's. Even bought the book on them. Also met a guy that was building one in our area at the time but never got the chance to go see it. Don't you just hate it when everyday life gets in the way of things?

[Chaz]

Sorry Ed. I get the black screen as well, for about 10 seconds or so, and then it comes on.
If ya get out my way, stop by for a personal tour!

Thanks, i will keep that in mind...if i ever get that far east.

Hi Chaz,
   Nice Pad.
I have no special vent for my electric fridge/computer/TV. There is a roof vent not far away. I keep it open varying amounts depending on the weather. If it's HOT out then I keep two vent fans on low from about 11:00AM to about 6:00PM. It keeps the heat from collecting on the ceiling. I also painted the ceiling with BusKote ceramic paint. We live in the sun because of our solar panels and have no air conditioning so we pay more attention to the air flow.

Just got back from a weekend at the NSRA Nationals in Louisville and I REALLY found out that the RV frige I have puts out some heat!! It worked great but the heat it puts off is amazing. My buddy threw some buns on top of some of the exit holes and it "baked" them bad boys!!  Bottoms were hard and tops were soggy.     

I guess these are fine if you want to use propane but I need to get a different one. Anybody interested??
