Cooling Fan Configuration

I used to work with the Fire Dept. When we would ventilate a building of smoke we would NOT have a fan pushing and another fan pulling.....You have as many pushing as you can and open a few windows.... If you are going to pay(Electricity) to have a fan running..... it is only natural to have it pushing cool air in and the hot air will find it's own way out! I have 4 fans (2 on each end) of the 220) with an open backed canopy and it works well. I do have a 1/2 HP chiller though.. My fans are on timers and turn off 20 mins. after the last MH turns off.. DO NOT RUN YOUR FANS 24/7 This will bring the temp too far down at night. Hope this rambling helps someone.....
