| 摘 要： | 针对数码涡旋压缩机的容量调节方式,将冷凝器内部流量的响应规律转化为外部一个变化的流量输入信号,建立数码涡旋变容制冷系统的冷凝器仿真模型;分析了热负荷、出风温度、制冷剂进口压力在不同容量输出下的动态变化特性。结果表明,在容量调节作用下,热负荷、出风温度呈现出周期性波动趋势,但其总体是随容量输出比例的降低而减小;而制冷剂进口压力变化不显著。

| Abstract: | According to the peculiar capacity modulation mode of digital scroll compressor,the response discipline of condenser's mass flow rate was translated to an external input signal.Dynamic model for condenser of the refrigeration system with digital scroll variable capacity was formulated;the dynamic characteristics of heat load,exit air temperature and refrigerant pressure at inlet of condenser were analyzed.The results illustrate that with the capacity modulating,the heat load and exit air temperature fluctua... |
