ABSTRACT
The article discusses the trends in close control air-conditioning (AC) systems as of May 2010. Experts reveal that conventional close control is no longer adequate for data centers and critical electronic environments. With continuous fluctuations of thermal loads in data centers, there is a greater need for precision control of temperature and humidity in AC systems. Precision AC systems can also react to changes in heat density that results from fluctuating loads of information technology (IT) equipment.
