Simulation Analysis of Temperature Field of Drying Chamber of Chrysanthemum Air Energy Heat Pump
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%.
