Abstract
The utility model relates to a greenhouse internal circulation and ventilation cooling system, which comprises a wet curtain and a negative pressure fan arranged on two opposite side walls of the greenhouse.The wet curtain is connected with the greenhouse water circulation system.A truss is arranged between the two opposite side walls of the greenhouse.The system is characterized in that a circulation fan is arranged on the truss.The full circulation and flowing of the cold air cooled by the wet curtain is performed under the action of the circulation fan and then the cold air is discharged via the negative pressure fan.The temperature difference and the humidity difference between the two sides of the greenhouse can be effectively reduced, so that the temperature and the humidity inside the greenhouse is uniform.Meanwhile, the consistency of the crop quality inside the greenhouse is also ensured, thereby facilitating the cultivating of crops.
Description
Technical field
The utility model belongs to the greenhouse technology field, particularly relates to a kind of greenhouse aeration-cooling system of indoor circulation.
Background technology
Owing to reasons such as northern China are dry, " wet curtain-negative-pressure air fan " cooling system is installed mostly in the northerly greenhouse.This system is made up of papery porous wet curtain, water circulation system, fan.Unsaturated air flow when porous, moistening wet curtain surface, the large quantity of moisture evaporation, the sensible heat that is embodied by temperature in the air is converted into evaporation latent heat, thereby reduces the temperature of air self.To constantly introduce in a steady stream through the cold air of Wet-curtain temperature reducing during the fan exhausting indoor, thereby reach cooling-down effect.
There is following shortcoming and defect in said system: the cold air of process Wet-curtain temperature reducing enters from a side in greenhouse, it is got rid of by negative-pressure air fan from the opposite side in greenhouse after by the greenhouse, the following current of cold air straight line is through the greenhouse, so can make the wet curtain side in greenhouse and divide and form the very big temperature difference and psychrometric difference between the pressure fan side, thereby cause temperature and humidity inequality in the greenhouse, finally influence the uniformity of crop quality in the greenhouse, and be unfavorable for the cultivation of crop.
Summary of the invention
The utility model provides a kind of simple in structure, the greenhouse indoor circulation ventilating system that can effectively adjust and reduce greatly temperature and humidity difference in the greenhouse for solving the technical problem that exists in the known technology.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: the aeration-cooling system of a kind of greenhouse indoor circulation, comprise the wet curtain and the negative-pressure air fan that are arranged at respectively on two opposing sidewalls in greenhouse, described wet curtain is connected with the water circulation system in greenhouse, be provided with truss between two opposing sidewalls in greenhouse, it is characterized in that: on the described truss circulating fan is installed.
The utility model can also adopt following technical scheme:
The quantity of described circulating fan is a plurality of, and circulating fan is distributed on the truss in greenhouse.
Described circulating fan is hinged on the truss by chain.
Advantage and the good effect that the utlity model has are: because the utility model adopts as above technical scheme: promptly add circulating fan between the wet curtain of prior art " wet curtain-negative-pressure air fan " cooling system and negative-pressure air fan, under the effect of circulating fan, cold air through Wet-curtain temperature reducing fully circulates in inside, greenhouse, discharge through negative-pressure air fan afterwards, it is poor to effectively reduce the temperature and humidity of following the both sides, greenhouse, make that greenhouse internal temperature and humidity are even, can effectively guarantee the uniformity of the inner crop quality in greenhouse, help crop and cultivate.
On the truss of inside, greenhouse, evenly be provided with the multi-section circulating fan, can make the abundant mixed flow of air.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, wet curtain; 2, truss; 3, negative-pressure air fan; 4, circulating fan.
Embodiment
For further understanding summary of the invention of the present utility model, characteristics and effect, exemplify following examples now, and conjunction with figs. is described in detail as follows:
See also Fig. 1, indoor circulation aeration-cooling system in a kind of greenhouse comprises wet curtain 1, negative-pressure air fan 3 and circulating fan 4.Described wet curtain 1 is installed in respectively on two relative sides in greenhouse with negative-pressure air fan 3.Described wet curtain 1 is connected with the water circulation system in greenhouse, and water circulation system is used to guarantee the humidity of wet curtain 1.Unsaturated air reduces temperature and enters the greenhouse from the side in greenhouse through wet curtain 1, and negative-pressure air fan 3 exhausting will constantly be introduced indoor through the cold air that wet curtain 1 is lowered the temperature in a steady stream, thereby reach cooling-down effect.Be provided with truss 2 above inside, greenhouse, by hinged several circulating fans 4 of chain, the quantity of circulating fan 4 is decided according to the greenhouse area, and circulating fan is evenly distributed on the truss 2 of inside, greenhouse on the truss 2.The quantity of negative-pressure air fan 3 also is a plurality of, and its quantity is decided according to the greenhouse area, and negative-pressure air fan 3 is evenly distributed on the side in greenhouse.
The above-mentioned circulating fan that is positioned at inside, greenhouse 4 work make the abundant mixed flow of cooling blast of inside, greenhouse, and effectively the interior temperature difference of decontamination chamber and psychrometric difference help the growth of crop in the greenhouse, can guarantee the straight unanimity of growth of chamber crop.
Claims (3)
