Installation and use of broiler house cooling pad

cooling pads must be used in the house for a certain period of time, and the cooling pads used in different houses are different. For houses with easy space closure and high cooling requirements, water curtain walls and negative pressure fans should be used. For independent houses with low cooling requirements and difficult to be closed, an independent cooling pad fan can be used. At present, most chicken farms use water curtain walls and vacuum fans.

It is very effective to use a cooling pad to cool down the house. However, if it cannot be properly installed and used, it will be counterproductive. Therefore, in production, the following points should be noted:

(1) The number of fans in the house and the area of ??the cooling pad should be determined according to the local climate, conditions, size of the chicken, and stocking density. Because the chicken is large, the number is large, and the heat is produced. At the same time, it is necessary to consider that after the cooling pad is used for a period of time, the effective inlet area will decrease. Therefore, when designing the cooling pad area, it is possible to increase the point appropriately. Under normal circumstances, according to the feeding of 1000O laying hens, if the average weight of the chicken is 1.8kg, 25m needs to be installed. cooling pad, 4 fans.

(2) The house should be as closed as possible. If you use a cooling pad to cool down, open the window as little as possible. If you have previously set up multiple windows, close them before opening the cooling pad. Because it is not sealed, no negative pressure can be formed in the house, and the cold air through the cooling pad is reduced, and the hot air outside the house will be drilled in.

(3) There must be a certain distance between the cooling pad and the chicken cage to prevent the cold wind from blowing directly on the chicken. It is recommended that the distance between the cooling pad and the chicken cage is 2 to 3 meters. At the same time, the proper distance of the section can also ensure that the cooling pad can not be damaged when transporting the cleaning tools and collecting the egg cart.

(4) Control the time when the cooling pad is opened. In view of the need to save water and electricity and actually cool down, it is generally preferred to open the cooling pad from 13:00 to 16:00 every day.

(5) At least three aspects should be checked before the cooling pad is opened: 1 is the fan normal; 2 corrugated fiber paper, water collector, water pipe is smooth, normal, whether there is sediment; 3 check the submersible pump inlet filter Is it intact, check the water circulation system for leaks.

(6) It is recommended to add a sunshade to the cooling pad to prevent the sun from directly shining on the cooling pad, which will increase the water temperature invisibly and affect the cooling effect.

(7) Pay attention to the temperature influence of water. Try to use deep well water. The colder the water flowing through the cooling pad, the better the cooling effect. When the water has passed several cycles and the water temperature rises (greater than 24 ° C), the water should be changed in time. The first time you use the cooling pad, you must add disinfectant (such as Baidu, anti-drug, etc.) to prevent the spread of the disease.

(8) When the cooling pad system is not used for a long time, it should be thoroughly inspected regularly to see if the blades are deformed. The bearings should be lubricated once a year, and pay attention to maintenance after use. In the cooling season, cotton blankets or films should be added inside and outside the cooling pad to prevent cold air from entering the house. Conditional chicken farms, when installing cooling pads, consider installing automatic roller blinds (such as plastic sheets or other). When the cooling pad is not used, drain the water in the water pipe and the pool and tie it with plastic cloth to prevent dust and sand from entering the pool and bringing it into the device. The pump motor should be stored to prevent damage from freezing. Use a shade net (cloth) to cover the curtain paper to prevent the life from being shortened due to oxidation.

(9) The water outlet of the horizontal sewer pipe of the cooling pad should be installed upward to prevent clogging and uneven water flow. The cooling pad drain pipe should not be completely closed for cleaning and disassembly in the future.

(10) During the use of the cooling pad, the cooling pad filter should be cleaned once a day. Blocking, deforming or collapsing the cooling pad will affect the cooling effect. The cause of the blockage is dust in the air, impurities in the water, poor quality of the cooling pad paper, deformation, cooling pad paper is not blown after use, or does not cause mildew on the surface of the paper curtain for a long time. Allow the fan to continue to turn for more than half an hour after cutting off the water source every day. Wait until the cooling pad is dry before stopping. This will prevent the growth of algae and avoid clogging the water pump, filter and water distribution pipe.
