I went to my local autozone and found chevy s-10 heater cores... u think they're okay?
chill king does make a water cooled air handler that can be paired with theire chillers, I spoke with them and they claim a 2ton paired with the airhandler will chill 8lights.
I remember someone on IC cooling a 8lighter with a 2ton just can remember his name, I just wouldnt rock chillking they are some poor customer service record
I am going ahead with my trial for a few reasons;
first, I am not cooling the lights with this system, they are already handled by a fully separate ducted air cooling system that draws air from outside the growroom and exhausts it outside.
Second, I need some hands on experience with systems like these, to develop a feel for how they work.
Third, I am trying to incorporate a way to build a reservior of cooling capability to take advantage of free cooling available with my municipal water supply.
Fourth, I temp checked the incoming water supply and it's 55 degrees fahrenheit at the bathroom tap! That's cold enough by any reasonable standard.
Fifth, if this isn't sufficient by itself, then adding a chiller to the circuit should be really simple, since the cooling system for the room will already be in place. This chiller should really not need to be bigger than 1/2T, especially if it has the help I've outlined above.
Sixth, I want to use this same system to cool my hydro systems as they are 75 or more without any and that's too warm.
I am not afriad to try something I think will work- and I'm not shy about discussing the results, whether they make me look like a genius- or a moron! I'll let you know how it goes, and what issues I encounter along the way.
55 degree spring water is what our geothermal chillers (ac and rez) use as well. We use thousands and thousands and thousands of gallons (per day).
You don't need to run straight to waste that would be ridiculous! The water will be barely a degree of 2 above tap temperature and still has much cooling potential.
I made my system so the reservoir was ~100l when the temperature of the reservoir rose to 18C it pumped cold fresh tap water into the reservoir which overflowed to waste until the temperature dropped to 10C then turned the pump off.
It took ~2 hours to raise the temps from 10C-18C and I replaced ~60% of the reservoir so roughly 0.5l's per minute for 1.2kw.
^ Yup... You do realize most pools are in climates where people actually go in them without fear of hypothermia, right? :-)
Your setup is typical... rooms can be kept at 10-12 degrees F warmer then the water being used.
That's cool shit. In most cases water would be too warm for 6-8 months out of the year.
This is very true I installed my pool specifically for grow cooling in the UK 8-9 months a year the pool is freezing! It's an above ground pool I bought cheap and relined being above ground it should leak off the heat nicely.
My plan is/was to grow only between Sep to May, I just checked the pool 7C. I have ~11000l's to play with and only 1-2kw of light to cool.
Read what he is trying to do.
He's going to tap in to his cold water line, run that through a coil in a barrel, then back in to his water tap. So cooling will only happen when you have a faucet on( shower, laundry, etc.) ie DTW.
