一、概述随着现代化建筑物和建筑群的规模愈来愈大,中央监督控制系统的应用也越来越多。采用这样的系统可以实现由一个人在中央控制室对整个建筑物或建筑群内的采暖、通风和空调系统的多至数千个部件的运行,进行监督和控制。这样一种系统所增大的初次投资费用,可以在数年内由于节能、节电、省人工等运行和维修费用的降减而得到补偿。 I. Overview With the ever-increasing scale of modern buildings and building complexes, there are more and more applications of central supervision and control systems. The use of such a system enables one person to supervise and control the operation of up to thousands of components of the heating, ventilation and air-conditioning system within the entire building or complex in a central control room. The increased initial investment cost of such a system can be compensated within a few years due to reductions in operating and maintenance costs such as energy saving, energy saving, and labor saving.
