dieselboy, thanks, that is exactly what I was thinking about. :cool:
ttystikk, how many items and what are you trying to cool with your Chiller? When the 2 rooms are up and running, will they both be veg/flowering at the same time or are you going to have them a few weeks apart? What A/C are you running or going to be running in the future?
I'll have to dig back through some of your threads again when I get this project done in a week. Haven't spent enough time around here lately and excited to get back to digging through threads again.
I know what it's like to search old threads for info, so I'll give you the rundown here:
2 Ton window mount ChillKing, pulls 8.5amps @240. Cools a 55 gallon drum reservoir, 1/2hp flotec pump circulates cold water through chiller and two 6 way copper Pex manifolds. Each 'circuit' from these manifolds has a 1/2" valve on intake and return side, to isolate it from the system for maintenance or removal without shutting the whole system down.
Each of the of the following is on its own circuit:
2 Ice Boxes cooling- and helping deheuy- a 16x9 bloomroom w/ 8kW of HPS in 8" magnum xxxl 'ocho' hoods. To be clear, these cool the ROOM air, air to cool the hoods is kept totally separate from the room and is NOT actively cooled, just pulled out of the house.
3 RDWC systems; two 100 gallon systems in the above room, one 75 gallon system in a veg room. Currently, this veg room is open and vented, running a swamper in there to boost humidity.
1 cooling coil under a 30 site aerocloner to help keep it cool. This wasn't effective, may place a short length of tubing inside the cloner to better control water temps.
During the 'day' cycle, the chiller runs 75-85%. At 'night' (my cycles are flipped so daytime is actually 9pm to 8am), it runs about 25% of the time cooling the RDWC systems back down to 60, to keep pythium and other rot issues at bay. They warm up to between 66 and 68 by the end of every day cycle, helps to keep up the metabolism of my girls. I may cover these buckets with refective material if this temp swing gets to be too power hungry, but I'm holding off at the moment because I like it and what it's doing for growth.
The mid-term plan is to add another bloomroom on the flip from the first, same setup or close to it. This summer, I will install Ice Box active cooling in the veg room and convert it to bloom, but it's only 4kW of sealed and vented hoods, this time Xtrasun 6". Also, I plan to add another Ice Box to the big bloom room, so that I can better control the dehuey effects of these units, and help out my poor overworked 70 pint Panasonic dehuey, lol. I also plan to install a couple Ice Boxes for human use; one each in an upstairs and downstairs living room, to condition the air. These will work on a speed control switch, running 6" centrifugal fans, so folks can keep cool this summer! This air finds its way through the veg room anyway, so it too will indirectly help cooling. ALL of this will easily be cooled by the current two ton chiller...
Longer range, I want to upgrade to Gavita's Proline 400v 1000w DE digital ballast and double ended bulb setup, to take advantage of its efficiency. This will require a cooling plant upgrade as 2 Tons wouldn't be able to handle 8kW unvented. I would still want remote ballasts, to run two rooms on the flip with one set of ballasts.
And, for those of you who remember my experimentation with light rotators, this is still in the works; details as I have them... The lastest wet dream lighting setup for my rotator would be one 1000W Gavita Proline reflector, and a 300w LEP running together, just like I did with my two reflectors in the pics on this thread; Built my own light rotator- wanna see?
