1. Keep the coop airtight
Under the condition of good airtightness, the longitudinal fan can be turned on to form a negative pressure in the house, so as to ensure that the outside air enters the house after cooling through the wet curtain. When the airtightness of the house is poor, it is difficult to form a negative pressure in the house, and the hot air from the outside can penetrate into the house through the air leakage, and the air cooled by the wet curtain will be greatly reduced, and the cooling effect is not good.
In order to increase the wind speed in the house, some farmers open the doors and windows or other air inlets of the house, so that a lot of hot air will enter the house, which will seriously affect the cooling effect of the wet curtain.
Therefore, during the use of wet curtains, all the gaps in the chicken house must be tightly blocked, including the roof, the junction of doors and windows and walls, and the fecal ditch. Enter the coop through the wet curtain.
2. Determine the number of fans in the house and the area of the wet pad
The farmer should determine the number of fans and the wet curtain area of the chicken house according to the climate of the chicken farm, the age of the chickens and the stocking density. Usually, the newly installed wet curtain has better permeability and higher cooling effect, but with the prolongation of use time, a layer of algae will adhere to the wet curtain or be blocked by minerals and scales, which will affect the air intake and cooling effect of the wet curtain. .
Therefore, when installing the wet curtain, it is necessary to consider the continuous loss of the effective area, and appropriately increase the wet curtain area.
3 .Keep a certain distance between the wet curtain and the chickens
After the air cooled by the wet curtain enters the chicken house, if it is directly blown on the chickens, the chickens will have a great cold stress response, so the wet curtain should be installed reasonably according to the breeding method of the chicken house.
First of all, for the flat chicken house, a special wet curtain room is usually built when the wet curtain system is installed, so that the wet curtain is kept about 1 meter away from the shelf plate in the chicken house, and the chickens on the shelf plate can move freely to avoid the cold. Air to reduce the occurrence of cold stress. Secondly, for caged chicken flocks, the distance between installing the wet curtain and placing the chicken cage should be controlled at 2-3 meters, which can not only reduce the impact of cold stress, but also facilitate cleaning of the chicken coop, chicken manure, egg collection and transfer of chicken flocks. , while avoiding damage to the wet curtain during the above operations.
If the wet curtain is too close to the flock, a deflector can be installed in the house, so that the cold air entering the house can reach the roof of the house along the slope of the deflector, and then mix with the hot air on the roof and fall to the ground or flocks to reduce the stress response of cold air to flocks. If conditions do not allow, a simple plastic sheet or plastic bag can also be used to replace the deflector to achieve the function of deflecting the wind direction.
4. Correctly install the wet curtain water pipe
In order to avoid clogging of the fiber paper on the wet curtain and uneven water flow, the sewer pipe of the wet curtain is installed in an open style, which is convenient for cleaning and dismantling of the water pipe. In addition, the fiber paper wet curtain with oil layer should be purchased to ensure a faster water flow speed and flush the dust and debris on the fiber paper in time.
5 .Shade the wet curtain
In summer, if the sun shines directly on the wet curtain, it will not only cause the water temperature of the wet curtain to rise, affecting the cooling effect, but also promote the growth of algae and damage the wet curtain and reduce its service life.
Therefore, when installing the wet curtain system, it is necessary to set up a sunshade outside to shade the wet curtain.
