Abstract:

With the Venlo greenhouse in Jianghan plain as research object，the effect of nature ventilation and mechanical ventilation on the Venlo greenhouse air temperature in summer was investigated.The results showed that the temperature inside greenhouse was always within 33℃ during the early summer while only natural ventilation was used.However，it was higher than 35℃ in the middle of summer.For mechanical ventilation，the temperature inside greenhouse was nearly within 35℃ during the early summer and midsummer.The period of high temperature was short.But in the height of summer，it was higher than 35℃ for a long time.From the above，it could be concluded that mechanical ventilation could meet the cooling demand for greenhouse in Jianhan plain.
