Data Center HVAC

Welcome to the "dungeon" known as the data center. I remember my first day reporting to the data center operations team three years ago. Even though I was a 10-year veteran of construction and commissioning who had seen it all, I have to confess... I was intimidated. (Laughs) "Is this the same HVAC I used to know?" "If I make a mistake here, will it make the national news?" That feeling of your heart racing with half-excitement and half-anxiety—you’re probably feeling it right now, aren't you? Once I actually got into it, I realized the skills I learned while breathing in dust at plant sites didn't just disappear. However, this thing called a "data center" definitely has a different personality than a typical building; it is much more prickly and sensitive. Working as a Lead Engineer, whenever I saw juniors falling into a state of "mental breakdown" with the exact same expression I once had, I would see my own reflection from three years ago. "Man, I had to learn the hard way by banging my head against the wall, but I want to teach these guys so it hurts a little less for them." This lecture was created with that single thought in mind. I’ve already gone ahead, experienced the trial and error you'll face, and even put together a complete "incorrect answer note" for you. I have packed in all the know-how from my 17-year engineering career—mixed with my blood, sweat, and refrigerant. So, please feel free to dig in, tear it apart, and savor every bit of it. If you ever think, "What on earth does this mean?" while studying, don't hesitate to ask on the bulletin board or via email. I will come to answer you faster than a UPS (Uninterruptible Power Supply) and with more energy than an emergency generator. Now, shall we get started?
