In the third stage, the column-shaped ice crystals grew mainly in its length and the ice crystals had the acerose shape gradually, and the growth rate of frost thickness increased rapidly to 3-5.8 times that in the second stage. It is found that the performance degradation of the ASHP unit was caused by the wall temperature drop of the evaporator, the rapid increase in the frost thickness, and the decrease in the air flow rate.18Refs.

对实验结果的分析表明，热泵机组性能恶化主要是由于蒸发器表面温度下降、霜晶形态变化引起霜层厚度快速增长及空气流动阻力增加导致风机流量下降三个因素之间形成的恶性循环所致，其中换热器表面温度下降引起的霜晶形态变化起到了至关重要的作用。
