Abstract
A greenhouse water film sunbeam-gathering heat-storage insulation system relates to a supporting facility of a planting greenhouse. When the greenhouse gathers the sunbeam to a proper temperature, a permeable system in a double-film interlayer of the greenhouse roof is started; water absorbed by a net in a water gravity interlayer flows downward slowly, and then flows into an underground insulating reservoir after absorbing the heat of light. under the action of water, the double-layer film of the greenhouse roof film forms a vacuum water film euphotic layer, which can ensure stable temperature and enough illumination in the greenhouse; the water circulation in the film takes away heat to prevent high temperature of the greenhouse film, thus prolonging the service life; the moisture and heat taken away by ventilation and heat dispersion can be reduced and the climate conditions in the greenhouse are stabilized; the water heat energy of the reservoir is recycled for heating at night so as to the temperature in the greenhouse and save energy source; the whole sunbeam-gathering heat-storage insulation system can be matched with the greenhouse, the greenhouse can lower the temperature in closed and non-shading way, therefore, heat is not discharged into the natural space, and plants can fully carry out photosynthesis without damage caused by high temperature; thus the greenhouse planting effect is improved.
