摘要
针对三峡库区夏季高温高湿的气候特点,通过比较湿帘-风机、风机-外遮荫、湿帘-外遮荫、自然通风-外遮荫、强制通风-侧窗降温系统的降温幅度的试验,指出在适合三峡库区的最佳降温方式为湿帘-风机的降温系统。试验表明:在天气晴朗,温室内空气湿度增大不多的条件下,采用湿帘-风机降温系统可使温室内气温比室外降低5～13℃,降幅可达10℃左右,并且温度的分布比较均匀。
Based on preliminary experiment and comparative analysis, Authors found a system to lower temperature inside greenhouse during the muggy summer by air blower-outside visor, wet curtain-outside visor, nature draft-outside visor, forced draft-beside windows and wet curtain -air blower cooling system, which is the most economical and effective cooling method adapting to the typical climate of the Three Gorges Reservoir Area in summer. Experiment shows that the increase of air moisture is not much in the greenhouse in sunny, it can effectively decrease the indoor temperature 5 - 13℃ lower than the outdoor, the decreasing can reach about 10℃ and moreover the temperature distributes uniformly.
