36'' chilled water pipes??
The tower will nevertheless require about 10,000 tonnes of cooling per hour, where one tonne of cooling is 12,000 times the
amount of heat that will raise or lower the temperature of one pound of water by one degree Fahrenheit.
Water that has condensed on the building from the air outside will be collected and used to water the surrounding
"It's so humid here in Dubai so the cooling system captures a huge amount of water," said structural engineer William
Condensed water will be collected and piped to a holding tank in the basement car park, from where it will be pumped into
the landscaping system.
About 15 million gallons of water will be supplied each year this way - the equivalent of 20 Olympic-sized swimming pool
Water pipes 36 inches in diameter will carry chilled water high up into the Burj Dubai for use in the building's cooling
Water used for fire protection sprinklers and hydrants, and for tap water, is pumped up and held in tanks. Gravity then
produces the flow when water is used.
Architect Eric Tomich said "very large" electrical cables will supply power through the tower, which will have its own
I wonder what size pump is needed for that??
5 out of 4 people don't understand fractions
36" I would love to see how they support something like that. Surly it cannot go 100+ stories straight up. Must be an impressive pumping system, and a farm of chillers.

Piece of cake. HV mains to a substation every 5-10 floors, they do it in cities everywhere. The cables would not be that large. Telco and Data would be lots of fiber backbone I would think. But 36" pipes full of water.....that’s heavy & large!
I toured a 15,000 HP ammonia plant under downtown Chicago, I think they had 60" CW lines going out of that plant. It was for the CW loop around the city.
i have seen 60" tower water return running horizontally across plant room floor, feeding into 8 1100 ton centravacs, but never saw anything that size going vertical.
absbertek, was that the com edison plant near michigan avenue, i think in a blue cross blue shield building?
48'' pipe vertical
At a chiller plant we are replacing three chillers they have 48" pipe going vertical 15 floors it's not uncommon just not that well known . I mentioned this thread to a co worker apparently in cinn, OH the have a company that supplies chilled water to downtown in 60in pipe horiz..
How do they support it vertically and handle the expansion?? I have seen lines horizontal that large but never vertical, especially at those kinds of distances.
