摘　　要：为了提高小型集装箱菇房气流组织均匀性,以上海冬季作为气象条件,将型号20FT的冷藏集装箱改造成的菇房作为研究对象,经设计机械送风方式并模拟验证送风合理性。经计算得到菇房总送风量为0.83 kg/s,送风方式为上送下回并利用孔板均流原理在送回风口布设孔板。孔板模型采用N点送风模型,通过CFD模拟技术模拟送风温度分别为10、11、12℃下菇房内气流速度场和温度场的分布情况。结果表明,采用孔板送回风的气流组织设计可使菇房温度场、速度场分布均匀,可使食用菌生长区域气流速度均在0.14 m/s以下;随着送风温度的增大,菇房温度均匀性逐渐提升,当送风温度为12℃时菇房各区域温差最小,此时菇房环境温度为12.09~13.69℃。CFD模拟可为优化菇房内部的气流分布、提高种植环境的稳定性和生产效益提供技术支持。In order to improve the uniformity of air distribution in small-size container mushroom house,20FT national standard refrigerated container was transformed into mushroom house as the research object in Shanghai in winter,the mechanical air supply mode was designed and the rationality of air supply was simulated.The total air supply volume of mushroom house was 0.83 kg/s,the ventilation method was down-return,the orifice plate was arranged in the return tuyere by using the orifice plate flow sharing principle.N-point air supply model was adopted in the the orifice model,CFD simulation technology was used to simulate the distribution of air velocity and temperature in the mushroom house with the delivery air temperature of 10,11 and 12℃respectively.The results showed that the temperature and velocity of mushroom house could be evenly distributed by using this air supply methods,and the air velocity in the growing area of edible fungi could be below 0.14 m/s.With the increase of the supply air temperature,the temperature uniformity of the mushroom house gradually increased.When the supply air temperature was 12℃,the temperature difference of the mushroom house was the smallest,and the temperature of the mushroom house was in the range of 12.09-13.69℃.CFD simulation could provide technical supports for optimizing the air flow distribution,improving the stability of planting environment and production efficiency.
