Testing And Simulation Of Temperature Environment In The Interior Of Greenhouse

The beginning of the paper should be the design and development of wireless, multi-point temperature-test system. Focusing on the greenhouses in the Hohhot, several points of temperature were measured on a two-dimensional cross-section, drawing some simulation results; qualitative analysis of the reasons for the phenomenon were done in the conclusion part; pointed out several factors that affect the distribution of the indoor temperature and air distribution law of motion.Corresponding position in the greenhouse measured temperature data in the night were used to examine the simulation results to the test, and CFD is a scientific method to solute heat transfer problems of greenhouse. At the end suggestion on improving heat preservation properties of greenhouse was proposed.Simulation experiments can truly reflect the heat loss process in Hohhot greenhouse at night under non-crop cultivation conditions. Pointed out that the mainly heat loss appears at the slope face. It is proposed that put a board above the crops, so that the air carries the heat will not go to the slope face, and ensure that the heat concentrated in crop around.
