The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

In the present specification, the terms "upper", "lower", "left", "right", "middle", and the like are used for the sake of clarity only, and are not intended to limit the scope of the present invention, and changes or adjustments of the relative relationship thereof are also considered to be the scope of the present invention without substantial changes in the technical content.

Example 1

As shown in fig. 1 to 5, embodiment 1 provides a wet curtain fan cooling system for a large-sized greenhouse which is ultra-long or ultra-wide. The large greenhouse can be divided into a plurality of greenhouse units in a partition manner in the width direction, and the gaps between the adjacent greenhouse units are used as air inlet channels, wherein the gaps are generally 4-5m wide and are a common term in the field. The top of the air inlet channel is provided with a top opening window, and when the top opening window is opened, outside air can enter the air inlet channel. An air inlet is arranged at one side of the greenhouse unit close to the air inlet channel, and an air inlet is also arranged at the other side of the greenhouse unit positioned at the edge of the large greenhouse. The air inlet is in a long strip shape, and the length direction of the air inlet is arranged along the length direction of the large greenhouse. The existing wet curtain fan cooling system has requirements on the width of a large greenhouse, and cannot be applied to the large greenhouse.

The wet curtain fan cooling system of this embodiment includes mount 1, fan 2 and wet curtain 3. The fixing frame 1 is fixed on a vertical column 4 of the greenhouse unit, and the fixing frame 1 is positioned in the middle of the greenhouse unit in the width direction and provided with a compartment 5. The fixing frame 1 is fixed on the upright post 4 of the greenhouse unit, so that the fixing frame 1 has a certain height from the ground of the greenhouse unit to avoid occupying the ground of the greenhouse unit and not influencing the ground area of the greenhouse. The fixing frame 1 is provided along the longitudinal direction of the compartment 5, and the longitudinal direction of the compartment 5 is the same as the longitudinal direction of the greenhouse unit, that is, the longitudinal direction of the fixing frame 1 is the same as the longitudinal direction of the greenhouse unit. The fixing frame 1 is provided with three side faces, one side face is horizontally placed, the other two side faces are obliquely placed, the horizontally placed side faces are kept hollow so that air can flow, and the obliquely placed side faces are provided with the isolation plates 6 which are used for isolating the inner side and the outer side of the greenhouse unit. The fan 2 is fixed on the fixing frame 1, and the air outlet direction of the fan 2 faces the outer side of the greenhouse unit. The partition board 6 is provided with a window at the position where the fan 2 is arranged so as to exchange air and ventilate. The isolation plate 6 is sealed with the fixed frame 1 and the shell of the fan 2, so that air leakage of the greenhouse is avoided. Fan 2 is equipped with a plurality ofly, and a plurality of fans 2 are along the length direction interval distribution of mount 1, and a plurality of fans 2 divide two to be listed as the setting, and the fan 2 dislocation distribution of different rows. The wet curtain 3 is arranged at the air inlets at the two ends of the greenhouse unit along the length direction of the greenhouse.

According to the cooling system of the wet curtain fan, the fan 2 is arranged between the wet curtains 3 at two ends of the greenhouse unit, and the effective cooling distance at one side is 40-60m, so that the width of the greenhouse unit can reach 80-120m, and the width of a large greenhouse can reach at least 80-120 m. The fans 2 are distributed along the length direction of the fixing frame 1, so that the greenhouse unit can be extended infinitely in the length direction theoretically; the large greenhouse can be composed of a plurality of greenhouse units, and the widths of the plurality of greenhouse units can be connected through the ventilation channel to form an integral large greenhouse, so that the width of the large greenhouse can be several times of the width of a single greenhouse unit; every greenhouse unit all sets up the wet curtain fan cooling system of one set of this embodiment, can increase the number of greenhouse unit wantonly to make the wet curtain fan cooling system of this embodiment can use super wide large-scale greenhouse.

When the greenhouse is used, the fan 2 starts to work, air in the greenhouse unit is pumped out of the greenhouse unit, low pressure is formed in the greenhouse unit, and therefore outside air enters the greenhouse unit through the air inlets at the two ends of the greenhouse unit; the air inlet is provided with the wet curtain 3, and in the process that the outside air penetrates through the wet curtain 3 and enters the greenhouse unit, the outside air and the wet curtain 3 carry out water-gas exchange, and the sensible heat of the outside air is converted into latent heat of vaporization, so that the outside air is humidified and cooled; cold air coming out of the wet curtain 3 flows through the greenhouse unit, absorbs heat in the greenhouse unit and then is discharged through the fan 2, so that the cooling purpose is achieved, and the greenhouse unit can be ventilated. The wet curtain fan cooling system of this embodiment easily installs and realizes, can reach original cooling effect, can increase the width in large-scale greenhouse again modularly, and large-scale greenhouse's length is unlimited, perfect solution current wet curtain fan cooling system to the restrictive nature of greenhouse size for large-scale, super large-scale greenhouse also can cool down through this kind of economical and practical mode of wet curtain fan.

In order to avoid outside air to enter into the greenhouse unit from fan 2 under 2 non-operating conditions, wet curtain fan cooling system still includes electronic top window 7, and electronic top window 7 sets up in the top of greenhouse unit, and electronic top window 7 is located the top of mount 1, when fan 2 opens and takes a breath for the greenhouse unit, and electronic top window 7 is opened, and when fan 2 closed, electronic top window 7 closed.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
