摘要
提出了采用排气温度为对象的膨胀阀控制方案,以绝热压缩排气温度为设定值,对蒸发器温度进行稳定化处理,拟合出蒸发器温度与环境温湿度的关系,获得了较为稳定的排气温度控制效果(偏差为±0.3℃),该方案可使制冷系统过热度小于MSS时得到较为稳定的控制效果。
An electronic expansion perature of adiabatic compressing valve control method is proposed based on discharge temperature. The discharge temprocess is assigned as setting value, and the evaporating pressure is stabilized by relating the Te with Td and Tw,. The effect of deviation of ± 0.3 ℃ shows this method is a good solution to refrigeration system control while its superheat approaches zero （below MSS） .
