Analysis of dehumidification method and discussion on improvement measures in solar greenhouse

The solar greenhouse is a passive agricultural facility building which can realize the anti-seasonal production. main enclosure structure of composed thermal insulation wall, roof and daylighting shed film. transmittance sunlight an important index affecting healthy growth plants in greenhouse. After testing, difference between radiation intensity received through film outdoor during day has large fluctuations. reason for this phenomenon that humidity large, there condensation on film, seriously affects sunlight. dehumidification methods commonly used greenhouses are summarized, their advantages disadvantages analyzed paper. In addition, problems existing current discussed. view characteristics high temperature needs ventilation cooling low at night to supplement heat, composite system with anti-condensation, heat storage, proposed, its performance analyzed.
