Temperature and Humidity Environment Simulation and Analysis in Multi Building Greenhouse
摘要
Abstract
In order to observe temperature and humidity distribution for each room of multi-room solar greenhouse in northern China and indoor cooling process in night, penmane-monteith method of soil moisture evaporation theory and computational fluid dynamics ( CFD) method was used to analyze the temperature and humidity field.When the test we arranged the temperature and humidity sensors, heat flux sensors and soil temperature ( moisture ) sensor in the green-house conducted a multi-site testing.Test and analysis result shows, the multi-room solar greenhouse indoor maximum temperature is 37 ℃, the night temperature is 5 ℃, the early morning minimum temperature is about 2 ℃.The evapora-tion rate of top soil during the 13:30 and 0:00 is respectively 6.07×10-5 kg/m2 · s和2.28×10-6 kg/m2 · s.The simu-lation shows that the maximum velocity of indoor airflow reaches 0.33m /s(appears in the room Ⅱ) when the average speed of outdoor wind is 0.5m/s at night.Finally, it is concluded that thermal insulation should be enhanced in order to meet requirements of greenhouse production in northern China.关键词
