Evaporative cooling system is a very effective cooling method for enclosed spaces. At present, most pig farms have installed evaporative cooling systems in their breeding and delivery houses. In summer, the cooling pad and fan will be turned on, and other ventilation holes and windows will be closed, creating a dense negative pressure environment. The evaporative cooling system can effectively reduce the temperature of summer pig houses and reduce the heat stress of pig herds, especially breeding pig herds. Some pig farms even use evaporative cooling pad systems in nursery and fattening houses
The evaporative cooling system is installed with a plastic evaporative cooling pad on one side and a negative pressure fan on the other side of the farm. Starting the negative pressure fan will create a certain negative pressure inside the breeding farm, and the external air will enter the room after being cooled by a cooling water curtain, thereby achieving the effect of ventilation and cooling. It is important to ensure that the aquaculture farm is well enclosed. If the enclosure is not good, the air cannot form convection, and the ventilation and cooling effect will be poor. The advantages of plastic evaporative cooling pad are long service life, good ventilation and cooling effect, low operating cost, and effective reduction of animal incidence rate.
The above are commonly used cooling systems in animal husbandry, and they are widely used in medium to large scale model farms. Farmers can choose suitable ventilation equipment based on the scale of the farm
Several major characteristics of evaporative cooling pad system and negative pressure fan
1. High efficiency, environmental protection, and energy conservation: The circulating system of tap water does not consume electricity
2. Natural ventilation and breathability: Cooperate with centrifugal fans to continuously change indoor air and maintain ultra-low temperature, refreshing and cool
3. Improving work efficiency: dealing with heat, increasing oxygen content, adjusting emotions, eliminating fatigue, and improving work objectives
4. Physical and mental health environmental protection: Zero pollution to the natural environment, in addition to reducing gas temperature, it also has the function of cleaning the smoke and particles carried by outsiders
