Hi,

I'm in charge to evaluate the Air conditioning system capacity of a new data center, among other things,

and I want to know if there is any methods that I can use to do that.

Thanks

Hi,

A few questions. Are you using an outside provider to maintain/assess your data centre on a regular basis? If not, I would highly recommend that you do so. A full service provider who can assess things such as:

HVAC and electrical (identifies potential areas for reducing energy consumption, calculates the loads on each UPS and per-rack enclosure, analyzes path redundancies, etc)

Thermal and CFD (measures air temperature and air flow at critical points throughout the data centre, identifies hot spots and airflow restrictions, performs a CFD (computational fluid dynamics) analysis in problematic areas - may include important variable such as air pressure, temperature and velocity; constructs an 'as is' floor plan identigyinf issues with airflow, obstructions and other areas of concern)

Data Centre "big questions" (potential revenue that is left, where the next failure will be and why, what repairs are really needed, etc)

...is going to be a huge benefit to the overall function of your data centre. I'm not sure where you're located, but Ainsworth is a great company to look at. Even if they're not near you, they have some good ideas which may be worth checking out:

Hi,

Thanks a lot for your replay, the problem is that the administration of my company, want to have an idea of the electrical consumption and eventualy the amoun of heat generated by servers before proceding with a third party like Ainsworth.

You mention CFD, I did a search on some available FREE software, all I found is 6sigmaDC whish is not free, do you know other ones??

Tanks again.

You can take the wattage of the servers, switches and other gear and get your consumption. Based on the amount of watts, you can multiply that by 3.412 and get how many BTU you have. Divide this number by 12,000 to get the amount of cooling you will need in tons.

Now this is an over simplification, I would add at least 25% or closer to 50% to these numbers to give yourself some wiggle room. It is far better to come under budget than go over.

Need any more help just ask.

This is not wrong, but is the old methodology.  Take a look at this link for a different mindset.

It might be the old methodology. However it will be what you will need for the RCDD exam. Thanks for the link.

Hi,

Y'v been very helpful, and yes I have another question, what about the postion of racks and cooling systems, because this factor affect the system parformance (Hot spots).

Thanks.

My apologies, my ignorance can sometimes be monotonous.  New, still planning, what stage are we talking about?  Where is the cooling, over or under?

Rack??  Watch your mouth!  There's no need for that type of language in here.  More than likely if any, by building out any DC with racks, (without a tremendous amount of other parts and coordination) The "Hot & Cold Aisle" technique will disappear.

No worries mate!  Do me a favor and tell Mr. Corker IT is good for him!    Cheers!

Certain elements of the building envelope play a major role in determining a building’s energy use and consequent costs and greenhouse gas emissions,

One of the key for establishing new data center is that the management should understand the cooling system and what are the measures to consider when it comes to data center. there are new strategies that arose in the field of data centers nowadays. They are implementing the use of green thinking.

DATA Centers Without compromise!
