That's not the question to ask.It's really simple, how much electricity is your chiller using and how much is 5% of your lights?
Shouldn't be too hard to answer really.
You sound like one of those burple fixture noobs who keep screaming they are using only half the electricity of HPS. You can keep explaining to them that they were deceived by the sales people, but they just don't want to hear it.This is ignorance talking. You need to educate yourself about HVAC in general and water chilling in particular.
I'm not comparing water cooled vs air cooled. I'm comparing water cooled with a chiller vs water cooled with a radiator.That's not the question to ask.
The questions to ask are:
How much electricity is your chiller using (water cooled setup)?
How much electricity is your AC using (air cooled setup)?
Which one gives you 5% extra light?
ttystick is talking BSYet he makes the singular claim that cooling his water to below ambient is giving him 5-10% extra efficiency for "free".
only chilled coolers can stay or go below ambient temps.what if we just over size the passive heatsinks and our normal room enviro keeps those sinks @ or below tj25 ?
Ok so the cob needs to be below ambient to see higher efficiency?only chilled coolers can stay or go below ambient temps.
No, I'm just cooling them to 55F.Ok i see now you guys are talking about cooling them down to 5c lol
Voltage gain is cumulative with low temp efficiency gain, bro- the 824 PPfD I thought I was getting originally had mushroomed to well over 925 PPfD according to some people's calculations. Not mine, I didn't know how to do the math.Never mind the fact that water and electronic stuff dont mix well therefore I personally could not sleep knowing my shit is 1 pinhole away from major catastrophic failures lol
But i can see where its beneficial to ttystikk because he already had his whole op setup for water cooling. 7% gains at optimal levels vs the cost to run said cooler seems like a wash,then you add the higher voltage and it is probably 4 or 5%.
I most certainly have, early and often. I speak regularly of my use of water cooled air handlers, which use cold water from my chiller to both cool and dehumidify the grow space.I dont think Ttystikk ever mentioned the fact that he already had a chiller in his setup. That would make an argument for "free lunch" but I don't know if I would go so far as to call it genius.
Not in this thread, which is the whole point. Not once in this thread did you mention you had already sunk the cost of the chiller and running it into your setup, otherwise I doubt people would have called you out on the "free lunch" idea. The argument there, Im pretty sure, was that you would be adding a chiller, not using an existing one... and assuming you didnt already have a chiller in your setup, your argument kinda implodes.I most certainly have, early and often. I speak regularly of my use of water cooled air handlers, which use cold water from my chiller to both cool and dehumidify the grow space.
"according to some people's calculations" ?? This is how Trump brings up topics. It doesnt work for him and it doesnt work here unfortunately either. What LEDs are you getting these calculations from? The ones in the OP?Voltage gain is cumulative with low temp efficiency gain, bro- the 824 PPfD I thought I was getting originally had mushroomed to well over 925 PPfD according to some people's calculations. Not mine, I didn't know how to do the math.
I'm actually getting light burn on my plants.
