Establishment and Experimental Verification of Temperature and Humidity Mechanism Model in Positive Pressure Greenhouse
摘要
Abstract
In order to accurately simulate the change of temperature and humidity inside the positive pressure greenhouse,the temperature and humidity mechanism model of the positive pressure greenhouse was established based on the law of energy conservation and mass conservation,and the model was simulated and verified by experiments.The results showed that when the external circulation was carried out,the root mean square errors of temperature in the planting area and the climate chamber were 0.9℃and 0.6℃,and the root mean square errors of relative humidity were 3.3%and 3.5%.The maximum absolute errors of temperature in the planting area and the climate chamber were 2.1℃and 1.1℃,and the maximum absolute errors of relative humidity were 4.4%and 5.6%.The root mean square errors of temperature in planting area and climate chamber were 0.7℃and 0.5℃,and the root mean square errors of relative humidity were 2.0%and 1.7%,.The maximum absolute errors of temperature in planting area and climate chamber were 2.2℃and 0.9℃,and the maximum absolute errors of relative humidity were 3.3%and 2.8%.The predicted results of the model and the measured values exited a good agreement.Therefore,the constructed model could accurately simulate the temperature and humidity in the positive pressure greenhouse,which provided a theoretical basis for the design and envi-ronmental regulation of the positive pressure greenhouse.关键词
