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 aux-iliary 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 high-temperature area accounting for 83%,and the average temperature in the drying room reaching 57.7 ℃.The temperature range below 55 ℃ accounts for 13%.
