Seedling greenhouse insulation dehumidifier

Abstract

The invention discloses a heat insulation dehumidifier for a seedling growing greenhouse. The dehumidifier comprises a box body. The inside of the box body is divided into an indoor air inlet area, an outdoor air inlet area, an indoor air outlet area and an outdoor air outlet area which are communicated with the inside and the outside of the greenhouse. An air inlet device is arranged in each air inlet area, the indoor air inlet area and the outdoor air outlet area are connected to form an independent ventilation channel, the outdoor air inlet area and the indoor air outlet area are connected to form an independent ventilation channel, and a heat exchange core is arranged at the intersection position of the two ventilation channels. The indoor air inlet area and the indoor air outlet area are separated through an air door plate capable of being opened, the air door plate is hinged to the heat exchange core through a rotating shaft and is connected with an air door switching device arranged on the box body, and the opening air door plate enables the indoor air inlet area and the indoor air outlet area to be communicated and meanwhile partitions the two ventilation channels. The heat insulation dehumidifier is used for heat insulation dehumidification of the seedling growing greenhouse, effectively reduces labor intensity of manual dehumidification, saves energy, is environmentally friendly, and is very suitable to be widely popularized and applied in agricultural seedling greenhouse cultivation.

Description

technical field [0001] The invention belongs to the technical field of floating seedling cultivation, and in particular relates to a heat preservation and dehumidifier for a seedling cultivation greenhouse. Background technique [0002] Floating seedlings are also called floating planting, floating gardening (Floating garden). Floating seedling raising is a new seedling raising method, which is to float the foam tray with light seedling raising substrate on the water surface, sow the seeds in the substrate, and the seedlings will take root and grow in the seedling raising substrate, and can absorb from the substrate and water bed. Water and nutrient seedling raising methods. [0003] The application of floating seedling raising technology is becoming more and more mature and widespread. One of the technologies is to heat the water body of the seedling pond, which can effectively increase the temperature of seedling raising. It is beneficial for people to operate in the gre...
