Hot weather cooling for livestock and poultry includes misting or spraying enough air velocity to encourage evaporation of heat via fogging or any other evaporative cooling pads as part of mechanical ventilation.
Evaporative cooling pads can be a great way of lowering the temperature in a facility. Through the saturated media, the pads draw in hot air from outside. The pad then absorbs water and cools down. The difference in temperature between the wet bulb temperature and the dry bulb temperature is called the wet bulb temp depression. This determines how much cooling can be achieved.
Evaporative cooling pads are a significant investment. Users are often not taught how to maintain their pads or neglect regular maintenance. These guidelines will help you keep your pads in good condition. These guidelines will give you many years of service before the need for replacement pads.
It is crucial to ensure water quality in an evaporative plant. It should have a pH between 6-8. If the pH is higher, acidification may be recommended. It is important to drain some of the water from your system. Water evaporates salts and minerals, which can be left behind in the water. Bleeding off water is the best way to ensure that minerals are not diluted. Deposits can form on the evaporative pads if there isn’t enough bleed-off. They can reduce the efficiency of evaporation.
Attention to algae. The padded media can be damaged by algae. Algae can cause damage to the pad media by reducing airflow resistance and the decomposing cellulose pad material. These are some of the algae-control strategies:
A) Chemical treatment is necessary.
b) Protect the sump and pad from direct sunlight
c) Make sure that your pads dry completely every 24 hours. This can be done in many ways. You can set the ventilation controller to activate the system only at night. You can also set the system to a 24-hour timer so that it turns off the system for a few hours in the morning.
Visually inspect the pads to see if there are any signs of sagging or damage. Dry sections could indicate insufficient flow, a failed pump, or plugged water distribution pipe holes.
Inspect the sump for debris, such as leaves, tree seeds, insects, grass clippings, and dirt that has been washed into them. This is food for algae to get rid of it first. Then, clean out the sump from any grass clippings or mowing debris that may have been left in there.
You should be aware of scale buildup. If scale buildup is apparent, increase the bleed rate.
Pay close attention to the appearance and growth of algae. You can adjust the drying time of your home or look at the chemical treatment methods if you see algae.
It is important to drain the entire system and disinfect it. The upper evaporative cooling systems should be cleaned before each season begins, July, and after it is turned off. If pads are left on year-round, they can collect debris. They should be removed at the beginning of each season.
Guidelines for Chemical Treatment
Two treatment methods are recommended: quarterly and continuous cleaning. If necessary, you can also use the optional third method. Follow the manufacturer’s instructions. You can reduce the pad’s lifespan by not adding bleach (chlorine) or bromine. Compounds containing quaternary nitric acid should be used for continuous treatment as an Algaecide. For cleaning, it is recommended to use compounds that contain quaternary ammonium.
