本文提出了一种创新的光电技术,用于检测冰箱或冰柜应用除霜控制领域的霜冻。实验是在自然对流条件下利用小型实验室测试段进行的。实验证明了新技术的两个令人愉快的特性,“开关”和“线性”。第一个属性提供了对除霜控制策略的有效判断,而第二个属性适合于开发霜高度的精确测量。为了开发该技术,研究了影响性能的特性(电流、环境温度、金属表面温度、光强度和传感器位置)。
An innovative photoelectric technology is presented in this paper for detecting frost in the field of defrost-control of refrigerator or freezer applications. Experiments were conducted with a small-scale laboratory test section under natural convection conditions. Two agreeable properties of the new technology, “on–off” and “linear”, have been demonstrated by the experiments. The first property provides an effective judgment of the defrost-control strategy while the second one is suitable for developing an accurate measurement of the frost height. The characteristics (electric current, environment temperature, metal surface temperature, light intensity and sensor location) that affect the properties were investigated for the development of this technology.
