Is that the white wire in the pic of the front??
And she is running now..been running for 10 minutes...lol...i got mad and gave it a bit of a kick..been running since...
Yup, thats it .locate it to a warmer spot if you can , like on the condensor.
thats the spirit! lol.Quote:

lmao...i stuck it inside the heater on the wall right behind the A/C...thats what i figured i should do...set it to somewhere warm so it fools it into thinking it needs to be cooler!
yep now get a temp guage and see what it pulls down to, and get a pic of the frost for fun.lol.Quote:

Did you remove the fan and the thermostat from the evap?Quote:

The bigger one is still in a window waiting to get removed on wenesday, it works alot better. The fan motor has completely died in it and when I was running it yesterday it got the evap down to 0c very quickly with no cooling on the condensor, it overheated before it could really ice up but :D
Edit: I've got some more pics, I'll post them up when I get home from work :)
No frost at all..it is cold to the touch but there is no frost...something must be wrong :(Quote:

Yup, we still got a fan blowing air through it. its most likely a squirl cage type,underneath that housing your were having trouble with. this is the fan that needs to be removed. remove the fan from the shaft and saw the shaft off,or just saw the shaft to remove the fan if you can get to it.the 2 fans will most likely share a single shaft, so disabling the fan motor wont help as you need the other fan running for the condensor, sorry I forgot to mention that important detail, lol.
these things wont frost up if they are still trying to cool the entire room.
The fans removed from the evap.Quote:

I can't find thermostat as such, just as piece of hollow hose that sits on the front on the evap, I routed that under the compressor. The first 4 'loops' of the evap get cold but it takes a very long time for the rest of it too come down.
It will completely freeze up the first 4 but the last couple stay at room temp.
well, my thermostat was broke or missing - or both ;) so i had to short it so to speak.. so now it will always run, which probably isn't necessary to cool my unit down good.
conflict, the last two pics you posted are your condenser, the coils are the evap and why the hell did they get hot?? (or did i get something wrong). btw if the whole rig has been upside down, you would flip it back to normal and have it rest for some hours - i was told 24hrs should be best - to let the oil settle at the bottom of the compressor. i know i always did this - maybe i'm being to "safety first" ;), but hell it won't do you no harm, just a test of patience, lol
Well...i finally figured out my game plan and I ended up taking a bunch of new pictures......not sure what the heck is going on though because i use a digital camcored to take pics and then a tv capture card to pull the pics and save them...my software for the card is refusing to work so im stuck explaining this all right now.
Anyway, i cut through the casing with a pair of bolt cutters and now have a safe route to sinply lift the condensor, evap and compressor all out of where the sit right now...once that is done i "should" be able to safely bend the evap to the opposite side of where it sits now so that i can put it in the cooler. It looks as if there is plenty enough line.
My only worrry is the fact that there are two hoses on the bottom and two on the top...gonna be a big trick to succesfully bend everything with no problems.
Anyway, she is now frosting up very nicely and the entire evap is layering up ith frost in literally seconds...looks as if a 10,500 BTU a/c is gonna do the trick !
i am done for the night....gonna play a game of NHL 2004 and then sleep...thanks for the help guys..more to come tommorrow!
Ok guys....i lost alot of sleep thinking of my plan for the night and the biggest problem I have right now is the fan. From my understanding it is NEEDED for the condesor.
Is it only needed to help cool it?
Se the big problem is the way this A/C is set up the lines go through the big bulky metal casing that everything is placed in. I succesfully cut through it and I can raise everything out of it and I plan on giving it a new home on a wood stand. But my problem is what to do about the fan. It is mounted nicely in the middle and provides perfect blowing to all parts of the condensor.
Would it still work well if I took a farely large house floor fan and had it blowing on it? that would work the best because it would allow me to work with the evap, compressor and condensor in ANYWAY i wanted. The way this is set up Im gonna have to completely switch the side the evap is on to have room to place the evap in a cooler.
Anyone know if my floor fan will work?
It is absolutely essential that the condenser has enough air flowing through it to get rid of the heat. Will the floor fan work? I have no idea. The temperature of the air leaving the condenser should be no more than 10C higher than the temperature of the air entering the condenser, if that helps. It would be best to work with the original design as much as possible.
The word "only" does not belong in this sentence. Insufficient airflow can destroy the compressor. It is important.Quote:

Well what doesn;t work about that is the fact that the original design of the casing leaves me absolutely NO room to move the evap more then an inch or two in ANY direction..in order to move the evap i am going to have to completely raise everything into the air out of the casing and then bend the piping to the complete opposite side.... i suppose there is still the chance of bending it to the other side and then placing the condensor and compressor back where they currently sit
OK..i figured it out and dang i wish my capture card was working..i have the evap in the cooler sitting perfectly....ALMOST kinked a line but stopped just in time..hopefully it isn;lt weakened under pressure.....im gonna take a cinder block and place it in the old casing and place the fan that was in the A/C on the side of the condesor so that it blows just the way it was before..... im thinking this will work
Bending tools make the job SO much easier. The tool firmly grips the entire circumference of the tube while bending it, making it virtually impossible to kink it.
Hi folks, just got in from work. Sound like things are going well.Conflict, if you havn't already I would grab a garden hose and wash all the bugs and such out of that evap clean it up real nice so your not running debris through your coolant system.
OMG guys i need advice...ok im using a 10,500 BTU A/C...im assuming that means it is capable of reaching VERY cold temps with this form of cooling...well..i am using a anti-freeze that is suppose to be good to -64F at 60/40....well....i mixed everything together for awhile in seperated container and then poured it in there.....literally within minutes of starting everything up i had a half an inch of ice on the first foot of line of the evap...and now it is rapidly spreading. I am thinking that a solid layer of ice can;t be very good because then it won;t have all the "area" to cool...by area I mean amount of piping open...i hope that makes sense...
Any ideas.....should my temps be this cold?
Yea one of the first things i did was clean out the evap...lmao...i put it in the shower in the basement (just a single stall shower that is hardly used during the winter) and connected a hose to the water lines from the washing machine....cleaned it out nice.Quote:

Well guys...im not sure what to do..i added a whole nother thing of anti-freeze...but to no avail...my evap is currently a solid chunk of ice
Any suggestions
Your running r-22 it will only get so cold, mine is -25c. the 10.500 btu's means it will handle one hell of a heat load. I have foud that the ratings on the antifreeze jugs don't apply here lol.Quote:

Are you circulating the anti-freeze? It needs to be kept moving through the evaporator coils.
yep shut it off and clean it out .lmao.
you need methanol straight or a mix of methanol/water or methanol/antifreeze. I prefer around 65/35 methanol/antifreeze.
ideas? dont use antifreeze, use something that wont freeze at the temperatures your chiller is runing at ;-) i believe gas line antifreeze?? or denatured alcohol is what you want. just make sure you seal theres up niceley otherwise it will evaporate and you dont want to breethe too much of it.
cheers, owen
