Azarimy,
I am also curious about the question ask by TS. You have not answered it. All you did was describe AHU and Cooling Tower. I appreciate more explaination on the AHU. Like is air distrubute for a particular place and not everyewhere.

Thanks lin00b,
I get the cooling tower part. I still have problem with the AHU. If it is like the AC unit inside the house, can I say the it get the cooling power from the cooling tower? What I do not undersatnd also is the location of the "Bilik AHU". They dont not seem to be located in any strategic location to cool down the place like your AC unit.

Are you saying the AHU is the duct for the cooling tower? While at the AHU it get ducted to other rooms?
