Ten months ago, when I started this project of producing a series on algorithms for managing or planning a data center’s mechanical infrastructure, my thinking was that I could demystify the mechanical plant by breaking it down into discrete elements and making the...

A set of Excel tools will not make us a certified PE or replace the need for a PE or architectural engineer to design our data center. Or, obviate the need for a mechanical facilities engineer to oversee ongoing operation; however, such tools can provide us with a...

Last summer I thought it might be interesting to explore the different elements that contribute to the cost of cooling our data centers and explore the feasibility of developing some easy-to-use Excel tools to help in comparing costs of different design options and...

Is the time right for the 100 degree Fahrenheit data center? It sure seems like it should be with the ASHRAE TC9.9 guidelines allowing server inlet temperatures up to 95˚F for Class A2 servers, 104˚F for Class A3 servers and 113˚F for Class A4 servers. When we finally...

In this long series on cooling efficiency algorithms dating back to last September, I have presented tools for quantifying the energy use impact in the data center of: Pressure and temperature differentials across cooling coils Temperature differentials delivered to...
