suction gas meaning in Chinese

煤气。

Suction gas pressure goes up as the compressor run at the lower speed in the lower burthen , and this is beneficial to lower systems energy - consume . when the system is controlled by wvf , the discharge change of the evaporator is not linear ; the electronic expansion valve is adopted to regulate the system superheat degree , and the controlled object is parameter time varying , accordingly , the time varying controller should be adopted
在负荷较小时，压缩机采用低速运转，吸气压力升高，这对系统降低能耗是有利的；变频控制时，蒸发器制冷剂流量的变化并非线性；系统中采用电子膨胀阀进行过热度控制，被控对象具有参数时变的特性，相应地宜采用变结构的控制器。
