上海某化纤工厂,加工维尼纶纤维的车间,对于温度和相对湿度的要求较高。夏季,要求:温度t=26±1℃,相对湿度φ=6.5±5％。冬季,要求:t=24±1℃,φ=6.5±5％。该车间空调面积为2400m~2,所需风量为80500m~3/h,原来由常规仪表控制,现改用由上海交大制造的MIC—80微机和ACC—1型空调节能器来控制。微电脑对空调系统进行控制,首先要对控制回路送来的检测信号进行采样,即不断
A chemical fiber factory in Shanghai, processing Vinylon fiber plant, for higher temperature and relative humidity requirements. In summer, requirements: temperature t = 26 ± 1 °C, relative humidity φ = 6.5 ± 5%. In winter, requirements are: t=24±1°C, φ=6.5±5%. The air conditioning area of the workshop is 2400m~2, and the required air volume is 80500m~3/h. Originally controlled by conventional instruments, it is now controlled by the MIC-80 microcomputer and the ACC-1 air conditioner energy saver manufactured by Shanghai Jiaotong University. The microcomputer controls the air conditioning system. First of all, the sampling signal from the control loop is sampled, ie
