Study On Heat And Humidity Environment Of Seed Steel-structure Storehouse In Beijing

With the development of the modern seed industry, a new type of seed storehouse, which can store a large number of seed, called normal temperature steel-structure seed storehouse, was built. But there are no relevant standards to tell us how to build this storehouse, and we don't know the environment inside the built storehouse is safe enough for the seed to get through the hot summer, or to prevent the hurt of the low temperature and the quencher. In this paper, the research of the environment of this normal temperature storehouse is concerned, the factors that can infect the environment inside the storehouse are analyzed, and furthermore, optimizing of the structure of the storehouse was referred.1. For the normal temperature steel-structure seed storehouse, this paper sets up an unsteady state heat-transferring mathematical model. And compile a dynamic simulation proTabm for this storehouse. Using this model we can simulate the temperature inside the storehouse and the temperature of the inner side of the walls and roof.2. In the heat summer, through the test for the storehouse, we can declare that the temperature(25.8℃) and relative humidity(74%) inside it is a little higher than the safe standard(25 ℃ and 65%).3. Through the test in the winter, we can say this storehouse can prevent the seed from the hurt of the low temperature and the quencher.4. By using the model set up in this paper, the environment inside the storehouse is analyzed. And the influence of temperature inside the storehouse caused by the heat insulation of the walls, canopy, height of the storehouse, position of the walls are considered.
