Wet curtain cooling principle:
Wet curtain cooling mainly utilizes the physical principle that water absorbs heat from the air during the evaporation process of water, causing the air temperature to drop.
In practice, it is used in conjunction with a negative pressure fan. The wet curtain is installed on one gable or side wall of an enclosed building, and the fan is installed on the other gable or side wall. The cooling fan draws out indoor air, creating a negative pressure that forces outdoor air to flow through the porous wet curtain surface,
A large amount of heat in the air is converted to lower the temperature of the air entering the room by 10-15 ℃, and is constantly introduced into the room for heatstroke prevention and cooling.
Structure and performance characteristics:
*The wet curtain is mainly composed of polymer water curtain paper, which has been specially treated, with high structural strength, corrosion resistance, and long service life.
*It has excellent air permeability and water permeability, which can ensure that the water evenly permeates the entire wet curtain wall.
*The three-dimensional design of corrugated wet curtain paper provides the maximum surface area for evaporation for heat exchange between water and air, with high water resistance and large evaporation ratio.
*The outer frame of the wet curtain is available in aluminum alloy or galvanized sheet, which can effectively prevent rust.
Fan and water curtain cooling equipment for aquaculture farms
Benefits: 1. It integrates ventilation, ventilation, and cooling. Introduction to the advantages of ventilation and ventilation fans in breeding farms 2. Energy saving: low power consumption, only about 10% to 15% of traditional air conditioning. 3. Environmental protection: CFC free. 4. Good cooling effect: After the external air enters the room through the cooling water curtain, the indoor temperature on the side of the cooling water curtain can reach a cooling effect of 5-10 degrees.
5. High efficiency and cost recovery within 2 days. 6. Remove the turbid, stuffy, and odorous air indoors and replace it with the outdoor air. 7. Effectively controlling the indoor environment, generating different wind speeds indoors, resulting in a cool breeze effect and feeling exceptionally comfortable and refreshing.
8. Reduce sexually transmitted diseases and effectively prevent the widespread spread of viruses such as sudden influenza. Birds, mosquitoes, and flies are the vectors of the disease. Due to the negative pressure sealing of the water curtain ventilation system, the probability of vector transmission will be reduced, which will enable staff to work in a comfortable, safe, and reassuring environment.
Installation Design of Water Curtain for Farm Fan
1. Overall, the equipment Z should be installed on the exterior wall of the building to minimize the convective distance as much as possible;
2. Equipment can be installed on walls or windowsills, but the installation environment should ensure smooth and fresh air. Water curtains should not be installed at exhaust outlets with foul or odorous gases, such as toilets, kitchens, chemical exhaust outlets, etc. If there are not enough windows or doors for ventilation, wall holes should be opened for negative pressure ventilation to ensure the required air volume in the factory building;
3. The fan is installed at a distance of 1m to 1.5m from the ground to maintain convection at an appropriate height and create a refreshing environment.
4. There are generally two installation methods for the fan+water curtain ventilation system: vertical and horizontal.
5. To ensure that the rack structure at the installation position of the fan water curtain system is stable and strong enough to support the weight of the entire equipment and maintenance personnel.
