江汉平原地区Venlo型温室夏季通风降温效果研究
|
摘要
以江汉平原地区Venlo型温室为研究对象,采用自然通风和机械通风2种方式,研究其夏季通风降温效果。结果表明:自然通风降温方式下,在夏季初期,温室内的温度均在33℃以内,到了6月份及以后期间,温室内的温度存在较长时间高温期(高于35℃);机械通风降温方式下,在夏季的初期及中期,温室内的温度大多数时间在35℃以内,存在短时间的高温期,在盛夏期,温室内的温度存在较长时间的高温期;因此认为,机械通风能够基本满足江汉平原地区夏季温室的降温需求。
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.
