使用压力有关型变风量末端装置的分析

FEASIBILITY ANALYSIS OF USING PRESSURE DEPENDENT VAV TERMINAL

通过模拟 ,分析了变风量末端测量室温的时间常数对变风量系统的影响 ,结果显示如果变风量末端测量室温的时间常数在 30秒以内 ,那么可以在变风量系统中使用压力有关的变风量末端。所以通过降低变风量末端测量室温的时间常数 ,就可以在变风量系统中采用压力有关的末端以降低整个变风量系统的造价。

Analyzes the time constant effect of room temperature sensor of the terminal on the VAV system by simulation. The results show that we can use pressure dependent VAV terminal to get satisfied control results approximately if the time constant of room temperature sensor is less than 30 second. By decline the time constant of the room temperature sensor of the terminal, we can use pressure dependent terminal to cut down the cost of the VAV system.
