【摘要】 对热力膨胀阀和电子膨胀阀控制下陈列柜内的温度分布做了实验研究。结果表明,在热力膨胀阀控制下,陈列柜内的温度分布情况与电子膨胀阀相差不大。在目前的实际应用中,热力膨胀阀基本能满足一般客户对陈列柜的使用要求,没有必要大规模进行电子膨胀阀的替代。更多还原

【Abstract】 Temperature distributions in a display case controlled by thermostatic expansion valve and electronic expansion valve are studied in this paper. The results show that there is little difference between the performances of those two kinds of expansion valve. At present, thermostatic expansion valve can meet the demands of general consumers. It is needless to make extensive substitution of electronic expansion valve for thermostatic expansion valve.更多还原
