北方日光温室的冬季除湿技术
Dehumidification Technology of Solar Greenhouse in Winter of the Northern Area
摘要
Abstract
According to high humidity characteristic of solar greenhouse in northern winter, high-performance dehumidifier should be used in solar greenhouse. The experiment mainly includes two phases. The first phase is to collect environmental parameters in the solar greenhouse to find temper-ature and time distribution of relative humidity inside the greenhouse. The second phase is to use de-humidifier in the experiment to assess effects of the dehumidifier under the set humidity of 70% and 60%, and finally measure the benefits and cost by using dehumidifier in winter time. The experi-mental results show that when humidity is set on 70%, the dehumidifier humidifies for 1. 12 h during 5 h, and the mean relative humidity is 63. 01%, which is reduced by 5. 06% compared with that when dehumidifier is not used. The winter income break-even point is 2. 287 yuan/m2 . When humid-ity is set on 60%, the dehumidifier works for 2. 02 h, and the mean relative humidity maintains at the level of 55. 10%, which is reduced by 12. 97% compared with that when dehumidifier is not used. The income break-even point over the winter is 2. 637 yuan/m2 . When ventilation and dehu-midification conditions are not accessible, we can use dehumidifier to prevent RH of solar green-house from being too high.关键词
