I have been trying out different ways of cooling my wort. I picked up a 50ft CFC and decided to see what difference the whirl-pooling action makes. I came across this method of cooling on the mr malty website (http://www.mrmalty.com/chiller.php).
Test 1 I boiled 5 gallons of water and used just the IC (no whirlpool) and here are the results.
Ambient temp: 82
Faucet water: 74
Flow rate: 2 gallons per min
212-140: 4 mins
140-100: 8 mins
100-90: 4 mins (somebody came to my door, so I had to stop the experiment at 90).
Total time 212-90 = 16 mins.
Test 2 same 5 gallons of water using the IC and whirl-pooling arm. Wort ran through a pump and back into the BK through this extra piece of copper creating a whirlpool.
Ambient temp: 82
Faucet water: 74
Flow rate: 2 gallons per min
212-140: 2 mins
140-100: 3 mins
100-80: 5 mins
Total time 212-80 = 10 mins.
Conclusion:
As you can see by whirl-pooling you can get your temperature down a lot faster (almost double). For this test I just used straight faucet water. When I am brewing for real, I would obviously use a pre-chiller and ice bath which will get the wort down to pitching temperatures.
Also the 6 minutes I saved = 12 gallons of saved water. So it works out better for the environment also!
