【摘要】 为了改善温室内气体环境的质量,提高温室生产产量和产品的品质,本文在运用流体动力学原理,分析射流式CO2气体补偿系统的设计原理的基础上,论述了系统的应用技术和方法。初步的应用表明该系统具有结构简单,自动控制性能好,造价低、运行经济可靠、补充CO2速度快、CO2浓度和气体流速分布均匀、增产效果和经济效益明显等特点。更多还原

【Abstract】 n order to increase yield and quality of the products with improving the air quality ofhe greenhouse, a new system of enriching CO2 concentration was developed for the modernized greenhouses. Based on the principle of hydrokinetics, the design fundamentals of the system were presented in detail, and the techniques of application on the system were discussed clearly with the concern. It is showed that the system is able to make up the CO2 concentration quickly, to get well-distribution for CO2, to improve the production and economic benefits obviously, with the advantages of simple structure, low cost and well auto controlling property.更多还原
