I wonder where they're going to put all those cooling towers? Maybe they'll use water from the river for the condenser loop?

 

There is a building in Seattle where, believe it or not, the fire sprinklers and the heat pump hydronic loop are one and the same.

 

I remember seeing this type of a design on a set of plans I was estimating about 20 years ago.

Told a few people about it and they convinced me that I had been dreaming.

 

I'm working down there on the site. I'll have an answer for you on Monday.

 

I visited Ground Zero last year. I'm very interested in how the project is going. Please let us know and post pics, if possible.
Thanks.

 

Mammoth and Trane got aced out........2 to 3 per floor 90 stories that a lot of Mcquays and scrolls.they will use Hudson River thru heat exchangers below ground level to cool the condensers with a sealed system vfd pumps,and all that stuff.they want to dedicated the running of the floors to each unit for tenent billing..they(local #94) run the condensers and the customer pays for the cooling and it will be BAS controlled to fine tune it.

 

This project drew me in from the start and the Freedom Tower is not your run of the mill office tower (not that anyone said it was). I still remember visiting my sister when she lived up that way and going to the Empire State building. We rode the elevator as high as we could and found it didn't go to the top (can't remember why) so we walked the rest of the way. The WTC was an awesome sight as was the rest of the view from up there.
I still remember exactly what, where, and who I was talking to the minute I heard the news. Hope to make it up that way again soon and see the new complex.
It's strange to remember something thats not there anymore, let alone not see it.

hi

so they are using the "hudson river" as part as condensor loop

 

I am sure they will be McQuay SWP units. They will have to have heat x-changers. They don't work worth a flip with open loop due to the condenser design.

 

hello

anymore waterloop designs????nice designs wow

 

Do they use central plants on ANY large buildings these days?

If so, please give me an example.

Thanks

 

water side econo with the hudson?

wonder ROC how are they going to waterside with the hudson,i did Newport Office Buildings back before 9-11 just out of the holland tunnel there in Jersey City.they had WC McQuays 75 tons 2 per floor ABB VFDs but dropped a fresh ait riser down the lenght of the mechanical rooms 2x4 dampered into each room?dead of the winter you could see your breath in the mechanical room..Schwarz prior to the PAR takeover wierd job and i was the OEM start up guy.so how are they doing econo in the freedom?did stuff for trane and they banged the towers at 45F during the winter and the retail unitsmissing the 3-ways to bad..

 

We were told last year McQuay does have the job.

We had a problem with one of their chillers last year and were informed at a job meeting. All packaged.

The Trade center did use river water in the past. Havn't heard if their doing it again.

 

I'm curious; Does anyone know what the new Freedom Tower will use for heat?? Perhaps heat strips?

Thanks

 

When working for Honeywell we studied the mechanical construction of the Twin Towers for various reasons. The engineering was unbelievable as just about each 4th or 6th floor had to have it's own maching room to handle the pumping of the water, for one, and the handling of the sewage.

One engineering example was given that if the water to feed a water fountain on the 1st floor were allowed to become common with the stand pipe of a (however many stories the Twin Towers use to be) there there would be X numbers of pounds of pressure sitting in the pipe in that water fountain. And if that engineering problem was not delt with by having different stations on the floors all the way to the top, well, if someone bent over to get a drink of water the pressure would due them in.

Then we got some figures on how sewage weight and speed from just one toilet on the top floor would fall that many stories, that was something else amazing. Now multiply that weight and speed by all the bathrooms on each floor.

It truely was an engineering feat. All the chillers were located on the roof penthouse with nothing left of them when they reached the ground, I was told.

 

DeltaT,

Do you know what kind of heat source will be used in the new Freedom Tower?? Am I correct with my quess on heat strips?

 

Don't know much about the new design of the Freedom Tower but from a economic/real estate stand point individual systems with separate tenant electrica meters would make sense as the old design of central chillers took up a lot of rentable floor space.

With the cost of rentable floor space in NYC, now at one of it's lowest points in history for some odd reason, every available foot of floor space is at a premium and won't be used by machine rooms and/or chillers/boilers, I'm sure.

 

The contract to McQuay is worth $15,000,000.00

 

Is McQuay handling the Freedom tower heating as well?
