Abstract
With the rapid development of industrial automation, DCS, PLC and other control systems in a wide range of industry applications, the installation of DCS, PLC, safety barrier, terminal cabinets, operator station, host computer control equipment and other key central control room in a factory or the core of enterprises are fully sure that, the central control room as part of the factory control system, its functional requirements (such as anti-electromagnetic interference, radiation, explosion-proof, waterproof, anti-static, anti-rat, a reasonable temperature, humidity etc.) in the design have been gradually standardized, improved; central control room in accordance with the layout of division, the basic include: operating room, PC room, cabinet room, power distribution room, corridors, studio support personnel, the general has a special focus on the central air-conditioning responsible for temperature and humidity control. However, we found that often in the summer air-conditioning control room in the system breakdown, over-temperature alarm cabinet room, and the DCS, such as e-cards to run in high-temperature environment prone to failure, many users had no choice but to emergency drilling blast walls of the central control room in the control room a few temporary tank installed air-conditioning units; and cabinet room temperature normal, operators often have to work wearing a strange coat.
