Greenhouse Natural Ventilation Models: How Do We Develop with Chinese Greenhouses?

Greenhouse technology has advanced over the past few decades in terms of environmental control (e.g., indoor temperature, relative humidity, and CO2 concentration). Ventilation is an effective way to adjust climate. Natural ventilation gained significant research attention recently because its low energy requirement. To evaluate effectiveness, rate often used. This review summarizes published papers related greenhouse ventilation. models are reported under different conditions, including wind-induced, buoyancy-induced, combined effects-induced greenhouses. The influencing factors described, such as wind buoyancy strength distribution, geometry, vent arrangement. Various methods assessing natural greenhouses introduced, consisting tracer gas techniques, pressure difference method, balance emptying fluid-filling box numerical simulation. values key coefficients deduced used literature listed. paper reports what been done world where we can start develop dynamic for solar tunnel-type China. Further valuable investigations discussed. distribution function with horizontal openings, a model cross-ventilation induced by force, analytical plant-considered higher applicability described. ensure accuracy models, other variables, especially geography-dependent ones, be added. More criteria suggested performance rather than provide comprehensive assessment.
