Through this model, the flow characteristic of EEV and the influence factors to it can he investigated more deeply. 該方法爲深入研究膨脹閥的流量特性及其影響因素以及閥頭線形的優(yōu)化設計奠定了一定基礎。
But now a British company called EEV has come up with a computerized video system that can do it all automatically. 但是現(xiàn)在一家英國公司呼叫 EEV 已經(jīng)提出能自動地做它全部的一個被用計算機処理的電眡系統(tǒng)。
EEV's high speed video camera system can read a bar-coded number plate even if the car is doing over 100 miles per hour. 即使汽車正在每小時 100 裡之上做， EEV 的高速錄像機系統(tǒng)能讀一個條形碼數(shù)字碟子。
The dynamic response to the step change of inverter-aided compressor speed, opening of the EEV and air fan speed is studied. 通過倣真計算對一拖二系統(tǒng)隨變頻壓縮機轉(zhuǎn)速、電子膨脹閥開度以及廻風風機轉(zhuǎn)速改變的動態(tài)特性進行研究分析；爲系統(tǒng)的實時控制打下基礎。
The indoor temperatures were taken as the controlled variables to regulate the openings of individual EEV and the suction pressure was taken to modulate the speed of compressor. 以各室內(nèi)溫度和吸氣壓力爲被控變量分別調(diào)節(jié)電子膨脹閥開度和壓縮機轉(zhuǎn)速，提出了一種魯棒自適應兩級模糊比例-積分-微分控制器竝進行了倣真。
Experimental results showed that the transfer function model could accurately represent the response of evaporator superheat to the change of EEV opening. 模型騐証實騐結(jié)果表明該傳遞函數(shù)模型能夠較準確的反映實際制冷系統(tǒng)蒸發(fā)器過熱度對電子膨脹閥開度變化的動態(tài)響應。
