In traditional design for a wire-tube type condenser, the air's temperature around it is considered to be the ambient temperature. In fact, the air's temperature is affected by the distance between the refrigerator's back and the wall and is heated by the compressor and condenser, so its temperature is not equal to the ambient temperature. In this case, the traditional design method is not accurate.

传统的设计冷凝器的方法，是把丝管式冷凝器周围空气的温度当作环境温度，而实际上，由于受压缩机散热、冷凝器加热、冰箱后壁和墙壁之间的间距的影响，冷凝器周围空气的温度并不等于环境温度，因而传统的设计方法并不精确，为了保证设计的精确性，有必要对冷凝器周围空气的温度进行研究。
