2、 Wet curtain+Working principle of fan cooling system:
The poultry house cooling system - fan+wet curtain adopts the principle of negative pressure suction, which can not only ventilate and exchange air but also achieve the purpose of cooling. No matter how hot the poultry house is: above 32 degrees or 45 degrees, or with a lot of ammonia, water vapor, or poor ventilation, it is very hot and humid. Equipping a fan with a wet curtain can keep your company's factory operating in a comfortable environment between 25 degrees and 30 degrees. The simultaneous operating cost is only one tenth of that of air conditioning

3、 Working principle of wet curtain:
Evaporation cooling is a natural phenomenon. Just as the wind blowing over the sea causes water to evaporate, resulting in a decrease in air quality, in order to artificially reproduce this physical process in workshops and greenhouses. You must have a surface that can vaporize water, a water supply system that can keep the surface moist, and control measures that allow air to pass through the surface and ensure the effective operation of the entire system. The cooling process of the wet curtain cooling system is completed within its core Olympic bid paper pad. There is a thin layer of water film on the surface of the corrugated fiber paper. When the outdoor hot and dry air is sucked through the paper pad by the fan, the water on the water film absorbs the heat in the air and evaporates into water vapor. In this way, the processed cool and humid air enters the room. This natural process is like the wind blowing over the water. The temperature at which a wet curtain can cool down depends on the dry wet bulb temperature of the air and the efficiency of the wet curtain at this time, and the cooling value is the product of the two. The cooling efficiency of a stable running wet curtain is usually constant. It can be seen that the hotter the weather, the better the cooling effect of the wet curtain. The heat source of the greenhouse comes from heat conduction and radiation. The heat load generated by heat conduction and radiation depends on weather conditions, greenhouse shading treatment, etc. All the heat that causes the greenhouse temperature to rise must be eliminated through negative pressure ventilation.

7、 Precautions for the use and maintenance of wet curtains
1. System usage
1) Water volume control
The water supply should ensure that the wet curtain is evenly soaked, with fine water flowing down along the ripples of the wet curtain. The water volume can be controlled by adjusting the water supply valve.
2) Water quality control
Keep the water source clean, with a pH between 6-9 and a conductivity of less than 1000 ohms. Regularly clean the water tank, circulating water system, etc. to ensure the cleanliness of the water supply system. To maintain good water quality (usually once a week), 3-5 ppm chlorine or bromine can be added to the water for short-term treatment to prevent the growth of algae or other microorganisms on the wet curtain surface. The concentration during continuous processing is 1ppm.
3) Water leakage treatment
Water droplets splash away from the wet curtain. Check if the water supply is too large: whether there are damaged wet curtains, broken edges or "flying edges".
There is water leakage at the joint. After stopping the water supply, apply silicone gel.
4) Wet curtain paper pad with uneven dryness and wetness
Adjust the water supply valve to control the water flow or replace the high-power water pump or large-diameter water supply pipe. Timely flush the water tank, water pump inlet, filter, spray supply pipe, etc., and remove dirt from the water supply circulation system.
2、 Wet curtain maintenance
1. Daily maintenance
Stop the fan 30 minutes after the water pump stops, ensuring that the dry and wet curtains are thoroughly dried once a day. After the system stops running, check if the accumulated water in the sink is drained to avoid the bottom of the wet curtain being immersed in water for a long time.
2. Wet curtain cleaning
Remove scale and algae from the surface of the wet curtain. After thoroughly drying the wet curtain, use a soft bristled brush to gently brush up and down, avoiding horizontal brushing. (You can first brush a part to check if the wet curtain can withstand brushing.) Then only start the water supply system to flush the scale and algae on the surface of the wet curtain. (Avoid washing the wet curtain with steam or high-pressure water)
3. Rat pest control
In seasons when wet curtains are not used, rodent control nets can be installed or rodenticides can be sprayed at the bottom of the wet curtains.
