摘要
采用画图方法具体分析了当空调房间热湿负荷变化时的调节方法,当余热Q变而余湿W不变时,可用1个平行四边形法则分析处理;当余热Q余湿W均变化时,可用2个平行四边形法则分析处理。同时分析了不同季节如何变露点的方法。另外为消除冷热抵消,也可以先采用变风量调节温度,再定风量变露点调节湿度(采用1个平行四边形法则处理)。
Using graphical method, this paper makes a detailed analysis of operation adjustment of air condition- ing unit when heat and humidity load changes in the room. When exhaust heat Q changes but exhaust humidity W remains unchanged, one parallelogram law can be used for analysis and solution; When both exhaust heat Q and exhaust humidity change, two parallelogram laws can be used. The paper also analyzes the method of changing dew points in different seasons, and points out that, in order to avoid counteraction between cool and warm air, wind volume can be first changed to adjust temperature, and then, in the condition that wind volume is kept constant, dew point can be changed to adjust humidity （in this case, one parallelogram law can be used ） .
