一、空调对象及其特征 1.电子计算机室本室由中央处理机及磁带、磁盘、穿孔卡片读出机、行式打印机等主要装置组成。为减少外扰而多用无窗,墙壁用隔热构造。由各机器发生的空调负荷几乎为显热负荷,另外还有墙的传热、照明灯具、工作人员的散热。室内的装置对环境条件要求很高。温湿度、空气的洁净度、机械振动、电气干扰等给予电子计算机极小的影响都时常会导致故障,所以对空调装置就提出了更高的要求。 First, the air-conditioning object and its characteristics 1. Computer room This room consists of a central processor and tape, disk, punch card reader, line printer and other major devices. In order to reduce external disturbances, there are no windows, and the walls are insulated. The air-conditioning load generated by each machine is almost a sensible heat load, and there are also wall heat transfer, lighting fixtures, and staff heat dissipation. Indoor devices require high environmental conditions. Temperature, humidity, air cleanliness, mechanical vibration, electrical interference, etc., which cause minimal impact on computers, often cause failures. Therefore, higher demands are placed on air conditioners.
