【摘要】 针对华东地区夏季高温高湿的气候特点,通过比较内遮荫、外遮荫、喷雾和内遮荫网上喷雾综合降温系统的降温幅度和降温效率的试验,指出适合华东地区的夏季最佳降温方式为内遮荫网上喷雾综合降温系统,它可提高该地区温室夏季的利用率。试验表明:在天气晴朗、自然通风的条件下,采用该系统可使温室内下部气温比相同高度室外气温降低2.4°～6.5℃,而内遮荫为0.2°～2.5℃,外遮荫为0.1°～1.0℃,喷雾为1.2°～4.4℃;但相对湿度增加了10%左右;降温幅度与室外干球温度呈线形相关性;降温效果受喷雾方式和天气状况的影响。更多还原

【Abstract】 Based on preliminary experiment and comparative analysis, Authors found a system to lower temperature inside greenhouse during the muggy summer by spraying water above the solar screen inside, which is the most economical and effective cooling method adapting to the typical climate of the East-China in summer. The temperatures of ambient air inside greenhouse 6℃ lower than those outside and 10℃ lower than those Inside comparative greenhouse in accordance with system being used while the mean effectiveness of the cooling system was 80%. In addition to, the paper has also discussed the relationship between the cooling efficiency and temperature of outside greenhouse and effects of types of spraying and weather. [更多还原
