Evaporative pads are a type of cooling system that uses the process of evaporation to lower the temperature of air as it passes through the pad. They are often used in air conditioning systems, particularly in arid or semi-arid climates where the air is dry and there is a need to add moisture to the air.
Evaporative pads are typically made of a porous material, such as cellulose or fiber, that is soaked in water. As the air flows through the pad, the water evaporates, and this process absorbs heat from the air, lowering its temperature. The cooled air is then circulated throughout the space by a fan or blower.
Evaporative pads are an energy-efficient and cost-effective cooling solution, as they do not require as much energy to operate as traditional air conditioning systems. They are also environmentally friendly, as they do not use refrigerants or emit greenhouse gases. However, they are not suitable for use in humid environments, as the air may already be saturated with moisture, preventing the water from evaporating effectively.
The lifespan of evaporative cooler pads depends on a variety of factors, including the quality of the pads, the frequency of use, and the amount of maintenance they receive.Our customers have reported using evaporative air coolers for more than 5 years with proper maintenance. However, for heavy use, we suggest replacing the evaporative cooling pads every 2-3 years to ensure optimal cooling performance.
To extend the life of your cooler pads, it is important to follow the manual's recommendations for maintenance and care. This may include cleaning the pads regularly, keeping them wet and properly soaked with water, and replacing them when they become worn or damaged.
To ensure optimal performance and longevity, it is recommended to perform a full cleaning of your evaporative air cooler at least three times per year, particularly if it is subjected to heavy use. This can include a thorough cleaning before the start of the cooling season in the spring, as well as mid-season and before storing the cooler.
Additionally, it is advisable to drain the tank and refill it with fresh water at least once a month, or more frequently if you are located in a particularly dusty area. By following these maintenance guidelines, you can ensure that your evaporative air cooler continues to operate efficiently and effectively.
If you notice that your evaporative cooler pads are showing signs of damage, such as mold, cracks, water leakage, or blockages, it is likely time to replace them. These issues can significantly impact the cooling effectiveness of your air cooler, so it is important to address them promptly. Replacing damaged evaporative cooler pads with new ones can help restore the efficiency and performance of your air cooler.
To begin the cleaning process, make sure to shut off the power of your evaporative air cooler. Next, remove the cooling pad and use a water gun to thoroughly rinse it. Be sure to use a gentle water pressure to avoid damaging the pad. Once the cooling pad is clean, dry it naturally before reinserting it into the air cooler. Don't forget to also clean the dust screen of the air cooler.
As long as the weather is hot, you can run your evaporative cooler continuously. If the temperature dips to around 68℉/20℃ at night, you may want to switch the air cooler to fan only mode. However, if the temperature remains closer to 86℉/30℃, it is fine to keep the air cooler running throughout the night.
The performance of evaporative coolers is optimized in high temperature, low humidity conditions, such as those above 85°F/29.5℃ with relative humidity below 50%. In contrast, they are less effective in lower temperature, high humidity situations, such as those below 75°F/23.8℃ with relative humidity above 60%.
The fan and pad cooling system relies on the principle of evaporative cooling to effectively cool the air in a confined space. It consists of an exhaust fan and a wet pad, typically made of a porous material such as cellulose or fiber. The exhaust fan draws hot air out of the room and into the pad, where it comes into contact with the wet surface.
As the hot air passes through the water-saturated pad, it absorbs moisture and becomes cooled. This cooled air is then circulated back into the interior space by the fan, effectively lowering the temperature in the room. This type of system is well-suited for use in greenhouses, chicken coops, and other confined spaces where traditional air conditioning may not be practical or effective.
A fan and pad cooling system is most efficient when it is hot and dry outside, with temperatures of 85°F/29.5℃ or higher and relative humidity below 50%. Conversely, it is less effective in cooler, more humid conditions, with temperatures below 75°F/23.8℃ and relative humidity above 60%.
For your reference, we have compiled a list of 15 points to keep in mind when setting up a fan and pad cooling system in a greenhouse.
The efficiency of an evaporative cooling pad is affected by a number of factors, including the temperature of the water, the speed of the wind, the structure and size of the pad, and its cleanliness. All of these elements are crucial for optimizing the cooling effect of the pad.
