Abstract:To optimize the uniformity of the thermal and humidity environment and flow field in the leaf storage room of a cigarette factory,the CFD simulation method is adopted.Taking the leaf storage room of a certain cigarette factory as the research object,the influence of different air supply parameters in winter on its thermal and humidity environment and flow field distribution is analyzed,and suggestions for optimizing the layout of temperature and humidity measurement points,the layout of leaf storage cabinets,and adjusting the air conditioning air supply parameters are put forward.The results show that the local abnormal temperature and humidity areas are mainly caused by the low temperature of the wall surface and the obstruction of air flow by the equipment.Compared with the upper surface of the leaf storage cabinet,the gap temperature of the leaf storage cabinet is 0.5 to 1.0℃lower and the humidity is 1.0%to 3.0%higher.Compared with a height of 4.3 m,the temperature at a height of 1.7 m is 0.3 to 1.0℃higher and the humidity is 0.5%to 2.0%lower.Under the same relative humidity conditions,a higher supply air temperature will cause the wind speed at the same position to relatively decrease,which is not conducive to the uniformity of indoor temperature and is prone to causing the humidity to exceed the standard.A lower supply air temperature is conducive to the uniformity of temperature and humidity distribution,but it is necessary to consider whether the indoor temperature field achieved meets the temperature requirements for the storage of indoor materials.
