[BLDG-SIM] Evaporative cooling

[Sangeetha Divakar]

great start! thanks Eric and Sayyed. I shall contact Martin and Nader for more information on CoolT. I had read about this software and the I am concerned about two issues - 1. does the simulation accomodate water spray through nozzles as against water pads? and 2. is the airflow rate given at the exit of the tower or at any point within the building? I am yet to finalyse the topic of study and have around 4 months to work on it. suggestions on current problems and potential areas of study in cool towers will be helpful.

Contact Martin Yoklic at the University of Arizona.  He works at the Environmental Research Laboratory (ERL) there.  His life work (started in college) has been on passive evaporative ‘Cool Towers.”  He has written several papers on this subject.  Frankly speaking, I could not find a simulation program that would dynamically adjust itself to a varying load like DOE2 does.  He has a software program which basically says if the ambient wet bulb temperature is “x”, the wind is “y”, the cross section area of the evaporative media is “a”, the elevation of the pads is “b”, the cross section area of the tower is “l”, the exit area is “m”, and given the thickness of the media “q” with a “z” approach, then you will get “c” flow of “d” degree air.

 

Can’t remember if that is exactly how it worked, but it is similar to that.  In order for him to perform the calculation, I had to provide him with a weather file with the variables I outlined above among other static variables.

 

He also has an Architectural degree.  Maybe he’ll try to lure you to the University of Arizona.  At least you’d still be in the PAC 10.

Hi all, I am a grad student of Architecture at the Univ of Oregon and also a new member of this mailing list. I am currently studying the use of Passive downdraught evaporative cooling in buildings. I wish to use building energy simulation tools to analyse the performance of different configurations of the towers. I hope u all can help me with pointers on how I could approach this problem. Your experiences with simulating evaporative cooling would be very useful. Which simulation tools accomodate simulating passive evap cooling. please give me some leads on it.  hope to hear replies soon. thanks a ton.
