So often I see people say my room temps are 78-80 during lights on and my water is 68F. Wow, without a chiller? How?
Anyway, in my UC system as well as my NFT strawberry patch I see super efficient exchange of energy between the room and water. In other words the water goes into the warm room and comes out heated fairly fast. Now, I have not insulated my buckets and pipes etc., but holy cow the heat transfer to the water is fast and efficient. I adjusted a vent in one room this morning and the room temp dropped and I saw the water respond in less than 30 minutes. I use a chiller on the cannabis rooms but in the food crop rooms it is not so critical and I see this effect every day. I am data logging 24/7 and track everything: water temp, air temp, humidity, light levels, chiller temps, fan movement, water level etc. If it does something we have a sensor on it!
So. when I added a chiller earlier this year I saw a huge reduction in AC costs and of course KWH I saw an immediate reduction. So, how is it some folks report not having to chill their water? How can there be such a dramatic delta T between their water and the ambient in the enclosure? Doesn't seem to make sense to me and if it is possible I want to know how to defy physics in my own grow:)
