Design and Simulation of Air Distribution in Container Mushroom House
摘要
Abstract
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-re-turn,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.关键词
