Chicken house using evaporative cooling pad can prevent heat stress
1. Working principle
The working principle of evaporative cooling pads is based on the natural phenomenon of “water evaporation absorbs heat”. When water falls from the top of the evaporative pad under the action of gravity, it forms a layer of water film on the corrugated surface of the pad. When the air flows quickly through this wet curtain, the water in the water film absorbs heat from the air and evaporates, thereby taking away a large amount of latent heat to achieve the purpose of cooling the air.
2. Structure and materials
Structure: Evaporative cooling pads are usually made of fiber materials or special paper, and their structure is similar to honeycomb to increase the evaporation area and improve cooling efficiency. The top of the pad is equipped with perforated pipes for evenly wetting the entire evaporative pad, and the bottom is equipped with a water collection tank and water tank to collect and recycle excess water.
Material: High-quality evaporative cooling pads are made of highly absorbent and water-resistant materials, such as honeycomb structure materials mixed with authentic wood pulp paper. These materials not only have a long service life, but also have the function of mildew and moth resistance.
3. Installation and use
Installation location: The evaporative cooling pad is usually installed on the wall or air inlet at one end of the chicken house, opposite to the exhaust fan. To prevent water from pouring into the house, the wet curtain should be installed at a certain distance from the air inlet (such as 30~50cm).
How to use: When using, make sure there is enough water in the water tank and evenly wet the water on the evaporative pad through the water pump. At the same time, start the exhaust fan to allow air to enter the chicken house through the wet curtain, thereby achieving the effect of cooling. When the temperature drops, stop supplying water to the evaporative pad, but the fan should continue to run to keep the chicken house ventilated.
4. Maintenance and care
Daily dredging: The spray hole should be dredged every day to ensure smooth water flow.
Debris cleaning: Insects, grass leaves and other debris on the curtain should be removed every 1~2 weeks, and pay attention to prevent rodent damage.
Seasonal management: In cold seasons, plastic cloth and other materials can be covered on the evaporative pad for insulation, or other air inlets can be used for ventilation.
5. Advantages and precautions
Advantages:
Energy-efficient: The power consumption of the evaporative cooling pad is only about one-tenth of that of traditional air conditioners.
Improve air quality: When using the water cooling system, negative ion oxygen will be generated, increasing the oxygen content in the air, which helps regulate emotions and reduce fatigue.
Increase ventilation: The entire indoor air can be updated once a minute, which helps keep the air in the chicken house fresh.
Precautions:
The evaporative pad cooling system cannot be used in naturally ventilated chicken houses.
The cool air entering the chicken house through the evaporative pad flows out from the other end of the chicken house after being heated by the body heat of the chicken. This temperature rise should not be greater than 2.8℃, otherwise the air flow rate and ventilation should be increased.
The evaporative cooling pad cannot be used continuously day and night, and the use time should be reasonably adjusted according to actual needs.
In summary, the chicken house evaporative cooling pad is an efficient, energy-saving and environmentally friendly cooling equipment suitable for chicken farms of all sizes. When using it, attention should be paid to reasonable installation, correct operation and regular maintenance to ensure its long-term stable operation and the best cooling effect.
