| 摘 要： | 在结霜工况下,蒸发器霜层将影响换热器的换能性能,需定期对换热器进行融霜,以提高其换热效果。本文对一种换热器在融霜时风机的运行与不运行的两种状态的性能进行了实验研究,分析并比较了换热器在两种状态下空气侧压力降及制冷量的变化情况。 |
| 关 键 词： | 换热器 融霜 压力降 |

| Abstract: | Fr ost growth on heat exchanger surface causes the performance of heat exchanger to decline.Eventually,defrost cycle is required and mitigate the performance degradation due to the frost in frost condition.The performance of heat exchanger under the fan running and stopping in defrosting period was experimentally studied in this paper.The air-side pressure drop and capacity of the heat exchanger under the two cases were analyzed and compared. |
| Keywords: | heat exchanger defrost pressure drop |
