密闭温室半导体制冷除湿及蒸散水回收灌溉装置的研制

为了提高人工补光温室的水分的利用效率低下的问题,该文以盆栽辣椒为研究对象,在密闭温室中试验种植,采用半导体制冷热交换和空气露点除湿的方法,对辣椒在发育期、开花期和结果期的蒸散水回收效率进行研究,对比自然对流和强制对流方式除湿的效果以及温室内外盆栽辣椒的生长情况。结果表明：冷凝板温度最低达5.5℃,满足露点除湿条件。在盆栽辣椒的不同生长时期,强制对流进风方式下的室内温度变化范围为18.6-28.2℃,室内湿度变化范围为41%-61.7%,除湿效果随温度升高而显著提高;日回收量从35 m L增加到375 m L,日灌溉量从132 m L增加到540 m L,蒸散水回收率最高达69.4%。密闭温室中...

Summary:为了提高人工补光温室的水分的利用效率低下的问题,该文以盆栽辣椒为研究对象,在密闭温室中试验种植,采用半导体制冷热交换和空气露点除湿的方法,对辣椒在发育期、开花期和结果期的蒸散水回收效率进行研究,对比自然对流和强制对流方式除湿的效果以及温室内外盆栽辣椒的生长情况。结果表明：冷凝板温度最低达5.5℃,满足露点除湿条件。在盆栽辣椒的不同生长时期,强制对流进风方式下的室内温度变化范围为18.6-28.2℃,室内湿度变化范围为41%-61.7%,除湿效果随温度升高而显著提高;日回收量从35 m L增加到375 m L,日灌溉量从132 m L增加到540 m L,蒸散水回收率最高达69.4%。密闭温室中盆栽辣椒能够正常生长,而室外盆栽辣椒生长受到抑制。人工补光密闭温室系统除湿效果明显,有效的利用回收水进行盆栽辣椒灌溉。结果表明,人工光密闭温室内半导制冷除湿和蒸散水回收的研究对提高温室作物水分利用效率有积极的推动作用。

To improve the water use efficiency of artificial light greenhouse, on the basis of the semiconductor refrigeration and the theory of air dew-point, the water transpiration by plants in greenhouse is condensed, which meets the requirement of the indoor dehumidification and recycling for irrigation. The studying object is potted pepper. The experimental period is from May 7 to July 4 including the growth period, the flowering period and the fruiting period. The experimental greenhouse is an airtight greenhouse designed with glass in t
