The basic physics of a data center is that electricity is converted to heat. Equipment in the data center expends power, generating heat, requiring air conditioning and ventilation equipment to keep them cool and running well. If the temperature rises too high, equipment will begin to malfunction or become damaged; as the internal components begin to swell and pull away from each other (or simply burn-up). The cooling system is also required to adjust the humidity of the air and to remove particles. Depending upon the climate at a data center's location, moisture may need to be added or removed. Similarly, the types and amount of particles to be removed from the air are determined by the location and external events. Data center cooling is a highly specialized area that uses precision cooling equipment that differs from the conventional comfort equipment. The combination of heat and the high sensitivity of electronic components in data center environments demand maximum availability and performance of the cooling equipment. Precision cooling systems have been designed specifically for this purpose. This 5-hr course presents a detailed discussion on the key concepts and practices relating to data cooling technology, air flow practices that improve conditions for IT equipment and reduce overall HVAC energy consumption. This course is aimed at mechanical engineers, electrical engineers, HVAC consultants and engineers, architects, O & M professionals, facility managers, estimators and general audience. No specific prerequisite training or experience is required. The course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of course materials.
