I to am interested in using a dehumidifier. I was at a store the other day that had a new small box style one. After I un-warpped the wire cords they had on the rollers to keep people from taking it off the shelf I looked as good as I could inside it. TO me it looked like the 2 things you see here the radiater and the evaperator coils http://3rotor.dns2go.com/images/FAQ/...04817.JPG.html were welded hard together :/ and also it was all very small :( just thought id share this info.

some of them might have the condensor and evaporator, mounted into a onepiece unit. i,e the side mounting plates of the two units are actualy forming part of the air duct between the two. I'm speaking from wild imagination here, never actually saw one like this, just that it makes sence to me, to manufacture it like that.....


in such a case, if it exists, some cutting would be needed to split the two appart....

might of been something like that. hey Rotor can ya accept my auth on ICQ? :)

Ive not used ICQ in ages.... i'm on MSN messanger now...

I've got a kenmore (750 watt version), it seems to work great. Have yet to actually use it with a heat load yet though, but I have gotten water/antifreeze to below -33c with it. It was very easy to take apart and get to work. I cut a hole in the side of it and have the tubing coming out of that, so I can have the original paneling on it.

000 - was that a fridge or dehumidifier? and how much did u pay for it? Are you cooling a second circuit or cooling using the refrigerant?

rotor - which models did u try modding cuz i want to buy my stuff through ebay.

BigBen2k - did u buy anything yet?

It's a dehumidifier, found it at sears it was a return and they only wanted $76 for it (originally $249), I guess cuz it's pretty dry here already and so not many people want a dehumdifier.

I'm cooling a second circuit with it. I just unbent the tubing to the evaporator and have it extended behind the unit inside 2 coolers.

is it the Kenmore 65 pint version?

Yup that's the one, probably overkill but it was what was on sale.

Nope, but since cost is an issue, I'm gonna stick it out for a lucky find, like 000.

bigben2k,
When you go to sears you should wonder around in places that you wouldn't think a humidifier would be at, because that's where I found the one I got. At my sears they have a bunch of returned stuff (mainly air conditioners) under a table tucked out of the way in the refrigerator section. It's kinda weird cuz that's upstairs and the dehumidifiers are downstairs (at my sears anyhow). The other weird thing was that at my sears they seem to make piles of returned things all over the store, so you can't just go to a certain area. Anyhow I figured I'd let ya know about that just in case it was like that at your store, I know I just found mine by accident.

Thanks, 000, that's a good tip! My Sears is all on one floor, but that's how most places are, here in Houston, TX!

Do you know what is the BTU rating for that dehumidifier? I looked all over kenmore.com with no luck.

I couldn't find anything either, but I found this:
Model# 05265
Auto Shut-Off: yes--compressor shut down
Collection Pan Size: 21 pints
Depth: 17 1/2 in.
Drain Hose Connection: yes
Height: 20 3/16 in.
Humidistat: humidity control
Number Of Fan Speeds: 2 speeds
Water-Level Control: yes (auto defrost control)
Weight: 45 lbs.
Wheels: yes
Width: 12 9/16 in.

pulls 6.5 amperes on 115 volts in this 750-watt unit

I'm not sure, I've tried to figure that out myself though and haven't been very succesful. The closest thing I've found is the wattage for the unit, I do know the compressor uses r22, which I think means it's fairly powerful. I also found that the fan (the only thing that I can think of besides the compressor) uses 0.4 amps at 115 v, which I think means it's a 46 watt fan. So that leaves about 700 watts for the compressor which is ~ 0.9 hp. I also know that the compressor is a rotary compressor made by lg electronics, but I couldn't find the model on their website. I'll look it over again tonight and see if I find any more info about it.

cool. keep me updated. from the horsepower of the compressor, i believe it will deliver promisable results.

Ok well this is what I found it says on the back of it it's 1.73L/kwh which since it does 65pts/24hrs means that it's a 2527.559 btu unit... that's if you can make that conversion (I think you can but maybe not)

Also there was a little more about the compressor
It's high side is 400 psig, low side is 150 psig, and it has 9.9 oz of r22 in it.

thx for the info man! I went today and got me the same dehumidifier u got. I paid for it 140 bux for a returned one. Open box. I took it home and stripped that baby apart. Too bad when unscrewing the radiator one of them just refused to come off. So i just left it and tomorrow i'll get something from home depot to get it out. i tried several tools but nothing worked. Oh well gotta wait then.

BigBen.. you ain't alone.. I'm beyond crazy..

Anyway.. if you did a phase change and used that peltier too.. I wouldn't be surprised to see you hit -50F under full load.. and -90F no load.. it's completely possible using a 226w peltier..

My phase system consists of a full water cooled condensor.. that is 20ft long and the evaporator is in PVC tubing.. my system water pumps through it.. 3 tubes.. 30ft of evaporator..

1/20HP compressor, r-134a.. not finished yet.. but I expect to see -25F on the evap once it's done.. Be very soon.

Hey, 000 you are here too :)

I am perm banned on ocforum.. But Sam is going to try and get that fixed for me.. I got banned for the stupidest reason.. Having an opinion.. sick touchy cry baby people..

Anyway.. :)

I got the stuff running but the Compressor is too hot. I got the 65pint version from my local Sears for 140. Its a returned item too. I ran it with Texaco antifreeze and the water got to 5Cish. The Peltier ran at -5Cish. I had to turn it off becuz the compressor got too hot.

Put a fan blowing on the compressor.. it will be fine then.. Doesn't need to be a HUGE amount of air.. Also.. if you cool your condensor better you will see better temps on the evaporator and lower temps on the compressor.. I didn't read this whole thread.. how are you running your setup?

He He...:p

Do you have any pics? You never mentionned anything about running the evaporator through PVC tubing!

I put a comair rotron and a 120mm 120v fan on it. It still goes hot. I am thinking that heat is okay because thats what the compressor does, increases pressure therefore making the refrigerant VERY hot.

Yes, the compressor compresses the freon .. adding heat energy to it..

Yea.. I got pics.. I'm just about done with the system..

IF anyone needs to bend copper tubing.. like 1/4" soft tubing.. for your condensor or evaporator and you need to make elbows n stuff.. Fill the tubing with sand.. make sure you fill the whole tubing with it.. cap the ends..

This way you can bend it around and even do tight elbows and the copper won't kink or crush down..

Also, if you have an air compressor and you can get a compression fitting for the hose.. fill the tube with sand.. then put the air compressor on it.. to pack the sand in really tight.. then fill the tube up more and keep doing that.. that way the tubing won't kink at all.. you can really work with it then.

You can get a 50lb bag of sand at home depot for 3 dollars.
