摘　　要：针对菊花烘干室热温度分布不均匀问题,利用ANSYS Fluent模块对菊花空气能热泵烘干室内温度场进行数值模拟。结果显示:辅助进风口宽度和进风量大小对烘干室温度均匀性影响较大;进风速度过低时会导致热量集聚在烘干室顶部;当进风速度达到1 m/s时,温度曲线较为平滑,均匀性较高;辅助进风口宽度为100 mm,进风速度为0.2 m/s时,温度分布均匀性最佳,烘干室内高温区占比达到83%,室内平均温度达到57.7℃,55℃及以下温度区间为13%。To solve the problem of uneven temperature distribution in the chrysanthemum drying room,the temperature field in the chrysanthemum air-source heat pump drying room was numerically simulated using the ANSYS Fluent module.The results show that the width and air volume of the auxiliary inlet have a significant impact on the uniformity of the drying room temperature.When the air speed is too low,heat will accumulate at the top of the drying room.When the air speed reaches 1 m/s,the temperature curve is relatively smooth and the uniformity is high.When the auxiliary inlet width is 100 mm and the air speed is 0.2 m/s,the temperature distribution uniformity is best,with the hightemperature area accounting for 83%,and the average temperature in the drying room reaching 57.7°C.The temperature range below 55°C accounts for 13%.
