District Cooling Chiller Plant

Dubai District Cooling Chiller Plant

In Dubai, the arab city trying to get the biggest of everthing", they are constructing a central cooling plant. It will be like the water company or the electric company and pipe chilled "water" into homes. I saw a tv show, discovery or national geographic channel, on a 150.000 ton chiller in the works. I am not a chiller guy, I only know how they work in theory. What do you think of this.........I think they are doing it now for stores but it will be residental with this new plant.


An air handler tied into the chiller line regulated down for the house and a selinod valve??

Like it or not Dubai is cutting edge, is this our future?

Why is this in the Jokes forum?

This is our past. There are plenty of district heating and cooling plants out there. most of them supplying chilled water to hospitals, universities, county and state gov. etc. Example: The TECO plant in Houston has one facility with 60,000 Tons, and another at 40,000 tons. They are in planning stages to increase capacity!

If they are supplying chilled water to a lot of individual houses, that would be new. I don't know how much play that would have in the USA, but there are some housing developments with small chilled water systems ((I would not call them plants) out there.

I lived in a neighborhood in St Paul called Energy Park. The entire neighborhood consisting of business, condos, apartments, stores, was run off a central plant that had ground source heat pumps. They sent chilled or heated water to fan coils in every space. My complex had trouble during spring changeover but otherwise worked great. I was there during the record breaking hot summer of 1988.

I noticed that most of the district cooling plants usually centrifugal chillers of 1000Tr or more are water cooled. Can they also be air cooled where water is scarce?

[Coolmaniac]

Nope, my guesstimate would be a 140' x 120' coil face area for 1000 tons, not to mention the line friction losses, control issues, power for all the fans needed, etc.:eek:

I had a building maintenance guy tell me that there was parts of Florida trying this. He was saying that if a new building was added, the piping was in a common underground corridor and they would have to have been certified clean on the new building before they would connect it to this common system. I've tried to look this up to verify this but I could not find anything. Maybe someone here has heard of this.

I didn't ask to many questions-he was a talker. He had a story for everything. (I think he might have even came over on the Mayflower):eek:

There are plenty of district cooling plants around in the us. Back in the eighties we put in a central plant of three 2800 ton machines that only cooled water that was taken from the river to the nuke plant. It was heating up too much on the way. One capitol city has a chilled water loop feeding the commercial office spaces and state buildings on the street. This was an idea that was great way back until the utilities got greedy and energy was cheap. There were many bldgs that used city steam. Now many have converted to their own boilers. The flow of central plants follows energy prices. As energy gets higher people look for better ways to save money, and central plants can do that. I beleive the Dubai situation is many large centrifs in the 2500 ton range in one central plant, not unlike many pharmaceuticals do here.

Jacksonville has a central chillwater plant that does the Stadium and some major downtown buildings. Kings Bay N.S.B. has a central chill/hot water plant. They have a lot of losses/drawbacks and most customers/buildings have to maintain their local plants as insurance.

The best idea is the co-generation plants [we take care of one] that generate electric power and provide waste steam as a byproduct.

knew i read about it somewhere. jork sold 46 machines to produce 130,000
tons to qatar ( that's 1 reason gas is $4+). completion was supposed to be 5/2008. doing the #'s - 2800t a machine. don't think yk's go that big. hey york guys! ya still making ht/ot's?

Hey BaldLoonie,we just did a job across the street from that plant,(Merrill Corp.) all fan coils.When i first got in the trade i worked on Bandana Square.Who did you work for when you were here?

York makes the YD chiller, I know they go up to at least 4000 ton.
We put several of them together in 2005, they were shipped to the Desert Palms Cooling District in Dubi. The chillers were built and put on some skids near out port. They were then put on a ship to Dubi.
There were two skids that had two 4000 ton YD chillers and two 2000 ton YD chillers.
