You know working as an IT professional, you tend to get asked a lot of questions from those that may not be familiar to Information Technology. One of the questions I get asked coming out of an IT computer room is: "Why is that room always so loud?" I try to explain that the noise is coming from our HVAC units, but after seeing the blank look on their faces, I realized that not many people may not understand what that means. So I figured instead of saying "You have to Google it...." (I'm pretty sure many people have done that), I figured it would be easier to explain it to those who are not familiar with it.
This is a standard HVAC unit. HVAC stands for Heating, Ventilation, and Air Conditioning. It is the technology of indoor environmental comfort. HVAC is important in the design of medium to large industrial and office building. For a computer room, usually mainframe computers generate a lot of heat which has to be cooled 24 hours a day, 7 days a week, 365 days a year. The HVAC provides the room with circulated and filtered cool air. Major units, like this one, are often cooled pumping air through the floor. This room is usually closed to keep the humidity controlled which is based on the equipment requirements. There is a reason that the HVAC is needed in the computer room which I will explain in next week's post.
