【摘要】 垂直农业是城市农业领域的一个新领域,它是指利用无土栽培技术（如水培法和气培法）在室内可控环境下培养植物。除了农业产出外,其对室内空气质量,尤其是CO₂浓度有着生态控制功能。通过实验研究,根据质量守恒建立微分方程,通过模拟回归的方法计算出植物净光合速率和室内CO₂浓度的关系。据此,对室内人数、垂直农业种菜规模以及室内CO₂浓度之间的关系建立了计算模型,并以Visual Basic.net开发工具为编程平台,利用计算机在迭代计算上的速度优势开发了室内CO₂浓度的模拟评估系统,动态模拟不同工况下全天室内CO₂浓度随时间变化关系。设计人员可以根据显示的数据图,调整室内垂直农业种菜规模和新风补充量,以达到室内CO₂浓度的控制和通风能耗的节约。更多还原

【Abstract】 Vertical farming is a new concept in the field of urban agriculture. It refers to the use of soilless cultivation methods（such as hydroponics and aeroponics） to grow plants in indoor controlled environment. Apart from agricultural production, it has ecological environmental control function to indoor air quality, especially to carbon dioxide（CO₂） concentration. Based on experimental research, differential equations were established according to the law of conservation of mass. The relationship between plants’ net photosynthetic rate and indoor background CO₂ concentration was calculated by the method of regression. Then, a quantitative calculation model was established to reflect the relationship between the number of occupants, the scale of vertical farming and indoor background CO₂ concentration. In order to take advantage of computers in iterative calculations, an indoor CO₂ concentration evaluating system was built using Visual Basic.net programming language aiming to dynamically simulate the variation of indoor CO₂ concentration under different working conditions 24 hour in a day. Designers could adjust the scale of vertical farming or fresh air supplement according to the displayed curves to achieve the target of CO₂ concentration control and energy saving in ventilation.更多还原
