Experiment and Application of Fast Dehumidifier in Greenhouses

摘要:
针对温室内部湿度高特点,采用再生式除湿机对温室进行除湿试验。试验主要分成3部分:第1部分根据温室内部环境铺设除湿管道;第2部分在温室内布置温湿度传感器;第3部分用除湿机做除湿试验。结果表明,10: 00—16: 00,温室内湿度从85%左右降至60%以下,湿度保持效果比温室无通风降湿设施的情况下好。在无法使用通风除湿的情况下,可以采用除湿机对日光温室进行除湿,控制日光温室湿度过高的情况。
Abstract:In response to high humidity inside greenhouse, a regenerative dehumidifier was used to conduct dehumidification tests in greenhouse.Experiment was mainly divided into three parts: the first part was to lay dehumidification pipelines according to internal environment of greenhouse; the second part was to install temperature and humidity sensors inside greenhouse; the third part was to conduct a dehumidification test using a dehumidifier.Results showed that from 10: 00 to 16: 00, humidity inside greenhouse decreased from about 85% to below 60%, and humidity retention effect was better than that without ventilation and dehumidification facilities in greenhouse.
