该研究采用水循环烟囱和水池系统,分别建立两种不同的封闭温室,比较两种方法的降温效果。试验结果表明,在地面100 cm高度处,使用水循环烟囱的温度比不使用降温系统的温度平均降低8℃左右。在地面100 cm高度处,白天湿度值均保持在45%~75%,适宜作物生长。利用水池降温除湿,相比附近另外一个封闭温室,距地面50 cm高度处温度降低10℃左右。11:30-15:00之间,地面50 cm高度处的最高温度为32℃,基本接近外界温度。封闭温室的湿度较适宜植物的生长发育,但白天50cm高度处的湿度保持90%以上。
The study uses water cycle chimney and pool system, respectively, to establish two different enclosed greenhouse, comparing the cooling effect of the two methods. The test results show that at a height of 100 cm above the ground, the water chimney temperature is reduced by about 8 ° C on average over the temperature without using the cooling system. At the height of 100 cm on the ground, the humidity during the day keeps at 45% -75%, which is suitable for crop growth. The use of pool cooling dehumidification, compared to another nearby closed greenhouse, height 50 cm above the ground at a temperature decrease of about 10 ℃. Between 11: 30-15: 00, the maximum temperature at the height of 50 cm above the ground is 32 ° C, which is basically close to the outside temperature. Closed greenhouse humidity is more suitable for plant growth and development, but the humidity at 50cm during the day to maintain more than 90%.
