Cooling Towers

[krb]

Can anyone recommend a good source of information for the design and thermal analysis of cooling towers? I have looked at some of CTI's info but I wanted some input before buying it.

I would recommend using data from other manufacturers and weigh it against any design demands you have. A good manufacturer I know is Evapco. They also provide Closed Circuit cooling towers as well.

The larger the physical size of the cooling tower, the more energy efficient it is. The least efficient are the forced draft units. Look at the various designs also from Marley and Baltimore Aircoil. They all work by rejecting the heat of the condenser water to the air by evaporation. The water is distributed equally to the cooling tower fill so it gets in intimate contact with the air either forced by the fan (blown through the fill) or induced draft (drawn through the fill by fan suction). Air can pass crossflow or counterflow to the fill with respect to the water flow. Along with evaporation, there is water lost to drift & some water must be bleed off under the water treatment program so as not to exceed the design concentration cycle. Typical total water makeup required for evaporation, drift & bleed is 0.05 gpm/ton. The heat evaporated is equal to the cooling tons + the compressor input. This is about 15000 Btu/hr. Figure latent heat of evaporation at about 970 Btu/lb, 62.34 lb/cubic, 7.481 gal/cubic ft & 60 minutes per hour, you get 0.03 gpm per ton for evaporation.

I recommend a course on Overview of Cooling Towers at PDHonline.org. This will clear your doubts

Check these two links. The first link is very comprehensive. A message popsup which tells you to download some Korean text. Just cancel it. A blank page appears then. Click Back and Forward arrows on the IE tool bar and the text appears. (Do the same whenever you want to see a different page) The data is very exhaustive.

Quark,

I am having trouble with your first link, any suggestions?
Thanks for the input from everyone.

krb!

I just opened it without problems. However, if you follow the procedure I stated above it will open up.
