空气流速对温室地下蓄热系统湿热传递影响试验（Influence of Air Velocity in Heat Exchanging Pipes to Heat Change and Water Vapor Transformation for Underground Heat Storage System in Greenhouse）
双层覆盖温室 地下蓄热系统 流速
2010/12/28
为确定双层覆盖温室地下蓄热系统换热管道空气流速对蓄热量和水蒸气迁移的影响，建立合理的运行模式，测试了该系统以0.6～2.8m/s的空气流速蓄热时换热管道进、出口空气温度和相对湿度、地坪温度、室外温度，计算了换热管道进出口处空气含湿量与焓及蓄热功率。结果表明，在冬季白昼晴朗时，系统分别以0.6、1.0、1.5、2.0、2.5、2.8m/s的空气流速进行蓄热，温室内热空气流经换热管道焓值明显降低，...
