建筑物通风.气配装置.节流元件和闭锁元件空气动力检 - This thesis analyzes all kinds of throttle components , points out the advantage of adapting eev , and analyzes the start - up and the discharge characteristics of eev , and dynamic response of refrigeration systems when the opening degree of eev is changed , etc . eev is placed into a tumoff position while the unit starts up , and after being kept for a period of time it is placed into a bigger position , after some more time it is put into a basic control
本文对比分析了冷藏箱制冷系统各种节流元件的特点，指出电子膨胀阀应用的优势，同时分析了电子膨胀阀的启动特性、流量特性以及系统在阀开度变化时的动态响应。电子膨胀阀在启动时应先使电子膨胀阀处于关闭位置，延时一段时间后，再将阀开至一个较大的位置，再延时一段时间后转移到基本的控制。 - According to a series of experimental data , the effect of following factors on the temperature in the ultra - low temperature box and cop are analyzed : the mixture composition , the pressure ratio and the return fluid extraction ratio of the rectifying column , the refrigeration capacity and the flow rate through throttle valve
并根据一系列实验结果，分析了工质配比、循环压比及精馏柱回流液的抽取率、加热量和节流元件对低温箱内温度和系统cop的影响，为今后的进一步研究指明了方向。
