Advice for chilled water system.

[000]

Over the weekend I found a humidifier that was on sale for cheap (79.97 down from 249.97, cuz it was returned), anyhow I took it apart and now have it cooling a cooler full of water. I've yet to buy a waterblock because I've been trying to figure out which one will work best with my system.

So what do you suggest for the waterblock? I have a 700 gph pump and will probably be using either 1/2" or 3/4" tubing.
(most likely 1/2, because I don't know of any waterblocks designed for 3/4").

The two things that I think need to be considered are:
How easy it will be to insulate (since my chilled water will probably create condensate) and how well they will work with a high flow pump.

Also I was wondering if anybody had any ideas on any way I could still use my bong cooler with my system, or will it only heat up my water?.

Thanks,

insulating isnt that hard, i suggest you get a maze 2 or something without a clear top, because the clear top would probably crack easily at cold temps... and would prob have other problems, whats the water temps???

Ok, so no clear tops (I thought that might be a problem, but they're so pretty :D )

After about an hour without any additives (so there was a block of ice around the evaporator) about 39 f, and was still dropping but not much point in going below that without adding something to the water.

What are people adding to their water now to go below freezing and still keep good heat flow?

Thanks,

Also does anyone know where people get that neoprene to cover stuff with?, or is there something better to use for insulation?

And does anyone know if there's someway to keep the compressor from stopping every so often (to cool down I suppose), should I just let it stop every so often, or should I try to figure out how to keep it from doing that? Would cooling the compressor unit make it stop stopping?

Thanks,

Depending on the type of dehumidifier you have, there could be a couple reasons why it keeps stopping.

Number one, dehumidifiers have a built in sensor that automatically shut it off after the room or area has reached the desired level of humidity. Depending on how you modded it, this sensor could be causing the shut offs. Secondly, some dehumidifiers have a "feature" that will shut it off after a while to prevent the buildup of ice on the coils. Again, I suppose it depends on what you did to it when you took it apart but these are just a few ideas. Hope they help.

Thanks, from what I can tell I believe I disconnected both the humidity sensor and the temperature sensor, which kept it running longer, but the compressor still shuts off (although the fan doesn't unless I turn the thing off and then back on once the compressor shuts off), the compressor is really hot once it shuts off so I'm thinking that there is some kind of safety thing built into the compressor also.

Do some compressors shut themselves off, or would it still be something that I need to disconnect from the controller? If I can find another thing to disconnect will this be bad for my compressor or should it be ok?

Thanks for the help,

I think you're right. It's probably built into the motor itself and there may be nothing you can do about it. Hopefully somebody with experience using a dehumidifier comperssor can enlighten us. I guess I'm not much help.:(

Good luck.

I have been refrigeration cooling for 6 months now so have a liitle background on the subject.
Firstly I recommend a read through the Project X thread where you will find a huge amount of information.
Your compressor probably has a over-temperature cutout or is contolled by some kind of thermostat. The compressor can be cooled using fans. My system runs about 14 hours a day and I have a pair of 80mm fans cooling the compressor which is running at around 50C.
As far as insulation goes I have been using neoprene and closed foam but have just upgraded and had problems with space around the socket and had to re-think the whole thing and have switched to styrofoam. Its a bit of a pain making the unit but basically you need a piece that is thick enough to go from the motherboard surface to the top of the water block. Initially make a cut out for the w/b that is a tight fit. Then take the piece and press it against the socket so it leaves impressions of whatever it touches and with a hobby blade or stanley knife basically carve the sections out so that it fits snuggly over the components until it is flush with mobo surface. Then make a top to cover the whole and its done. Its working really well for me at the moment and much better than the neoprene. Its a big plus because I'll not have to do the build again which is the case with neoprene and closed foam. There are many other things like grease for the socket.
With regard to flow I have found that slow flow is better than fast flow and currently run with a flow rate of about 2L/min.
Hope this helps.

Thanks, that helps a lot, been trying to go through the Project X thread, pretty good info (sure is long though).

i'v noticed that the swiftech blocks preform better with hi flow, that moght be good, but there rather larg.

hope this helps
