摘要
研究了在热泵工况下变化参数对风冷热泵蒸发器霜形成率的影响 ,获得了入口空气相对湿度、温度、流速以及翅片间距等参数对蒸发器结霜量和空气侧压降的变化规律。计算结果和实验测试的结果吻合较好 。
The effect of various parameters on the frosting performance of evaporator of air-cooled heat pump is investigated. The varied relations such as air inlet relative humidity, temperature, airflow rate and fin span effecting the rate of frost formation and air-side pressure drop have been obtained. The computing results have good agreement with those from experiment. The conclusions are of great significance on the design of finned-tube evaporator in industry.
