having a jet ski freestyle background riding/building skis cooling lines and efficiency has come up a few times in conversations... Anyway, I was thinking about wort chillers and getting the largest amount of cooling w/ the most efficiency. My mindset was always that higher pressure and increased flow does not always equate to more cooling, because the water travels too fast to properly exchange the heat therefore the pressure and flow need to be regulated in order to get the most efficiency. I picked up the quote below from a website and it seems to back up my way of thinking, yet I have seen other sites that say more pressure and flow will increase efficiency. What I do now is adjust the cooling till the water that is coming out is the hottest I can get it, which usually a very low flow. Is this the most efficient way to cool or just turn it up and don't sweat it? Anyone know the facts on this?
