| 摘 要： | 针对湿帘风机温室试验对通过湿帘后空气温度测量困难的问题,设计屏蔽送风式、屏蔽非送风式和非屏蔽式3种测量方法,通过试验对3种测量方式的准确性及误差因素进行分析。结果表明:屏蔽非送风式的测量结果受湿帘液滴附着影响较小,测量结果准确可靠;屏蔽送风式测量值较真实值小,误差范围为0.1～3.2℃;非屏蔽式测量方式容易受到外界环境因素的影响,误差范围-2.7～3.9℃,波动范围较大。

| Abstract: | During the operation of pad and fan system for greenhouse cooling,fog wafts appeared inside the greenhouse.If the fog adheres to a sensing part of a thermometer,measurement of air temperature through pad will decrease and cause errors.The study was conducted by three measurement methods which were non-aspirated thermocouple with shelter,aspirated psychrometer and bare thermocouple without the shelter.It was found that the result of the non-aspirated thermocouple with shelter provided the most accurate measu... |
