that's the answer I was looking for, as I am indeed in energy conservation... I thought you could go into the low 40's, or even 45 if the site can indeed handle approximately 50-52 degree chilled water. The reason i say 50-52 is because I've been told that the approach you described can be as...
You still have to set a parameter at which the system switches out of economizer mode. So that parameter would still be the return condenser water temperature? I.E. if you wanted your return condenser water temperature to be 85, then if it got over something like 89 (adj.), you would have the...
it is all one system. I would still have to try to figure out the best control strategy for the tower fans, but for now I would say it would be best to have some sort of return water temperature reset with a change in outside air temperature
What is a good wetbulb temperature to set as a maximum temperature to allow a water-side economizer to be allowed to operate in a water-cooled chiller application with cooling towers. This application is in the mid-west (st. louis)
