其控制装置由加工工具、能量传感器、温度传感器、加法器、调节阀、低温液体发生器以及前馈控制器和反馈控制器组成。
Its control device is comprised of processing tool, energy sensor, temp. sensor, addition apparatus, regulating valve, low temp. liquid generator, and forward feed and feedback controllers.
风量调节阀系阻性部件，存在较大的压头损失，须消耗大量送风能量。
The valve is an impeding part with larger pressure head loss and a lot of discharge energy consumed.
这种传统设计方法，调节阀至少要节流掉30%的能量。造成能源的极大浪费。
In this traditional method, the regulation valves consume at least 30% energy, which is very wasteful.
