Common Questions and Answers for Keruilai Industrial Cooling Fans

　　Keruilai industrial air cooler is an environmentally friendly ventilation and cooling equipment without compressor, no refrigerant, and no pollution. The system is simple, easy and quick to install and maintain. It is suitable for electronics, textiles, shoemaking, plastics, machine workshops, cigarette factories, and modern families. , offices, supermarkets, hospitals, entertainment venues, waiting rooms and other occasions. Recently, Keruilai has compiled some frequently asked questions about industrial air coolers. Here are the unified answers for everyone.

 

 

　　1. How does an industrial air cooler work?

　　Industrial air coolers remove heat through evaporation of water to achieve cooling. This cooling method is lower cost and more energy-saving than traditional refrigeration technology.

　　2. What is the difference between industrial air coolers and standard fans?

　　Standard ceiling fans increase indoor air circulation by rotating blades, so sweat on the human body evaporates faster, but the cooling effect is limited. The fan cannot operate in a closed space or in an area where the air flow velocity is greater than 6.4 kilometers/hour. If the ambient temperature is higher than the natural temperature of the human body (37°C), the rotation of the fan blades can only heat the human body but has no cooling effect.

　　Industrial air coolers can bring significant cooling effects to the surrounding air. By introducing moisture into the air and effectively circulating it, the Keruilai air cooler can significantly lower room temperature. Fans can only affect the body's perceived temperature, but industrial air coolers/cooling fans can reduce indoor temperatures by about 5°C. The evaporative refrigeration working principle of industrial air cooler/cooling fan (air conditioning fan) is more reliable and stable than air circulation. In addition, industrial air coolers/cooling fans (air conditioning fans) are much less noisy than standard fans.

　　3. Does the operation of industrial air coolers consume a lot of electricity?

　　Air cooling is an energy-saving cooling technology. The operating cost of an industrial air cooler is one-tenth that of a traditional air conditioner. A 2.2-ton split air conditioner consumes 2,200 watts of energy per hour. A Keruilai air cooler/cooling fan consumes almost the same energy as a traditional ceiling fan. The energy required by Keruilai air cooler/cooling fan ranges from: 105 watts/hour to 255 watts/hour.

　　4. Is it effective to use industrial air coolers/cooling fans in humid environments?

　　Although they work best in dry/arid conditions, air coolers/cooling fans can still provide effective cooling as long as the ambient humidity is below the saturation point. In other words, the air cooler/cooling fan can operate effectively when the air humidity is below 50%. The effectiveness of industrial air coolers/cooling fans will be reduced in moderately humid areas, but they can still achieve ventilation and air circulation effects. However, we do not recommend the use of industrial air coolers in areas with high relative humidity.

　　5. What kind of wet curtain is used in Keruilai industrial air cooler?

　　Keruilai air cooler/cooling fan adopts innovative honeycomb wet curtain. Honeycomb wet curtains have a unique cell structure similar to a honeycomb shape. This structure can produce a better cooling effect due to the increased surface area for humidity transfer in the air.

　　Both poplar wood and honeycomb wet curtains are all-natural and cost-effective. Industrial air coolers remove heat through water evaporation to achieve cooling. This cooling method is lower cost and more energy-saving than traditional refrigeration technology.

　　6. How to choose a Keruilai air cooler that suits my needs?

　　Keruilai supplies a variety of air cooler models for different occasions, which are designed to meet different needs and different places of use. Select a cooling fan based on several factors, including the size of your room, the local climate, the structure of your building, your budget, and your requirements for special features. Based on your needs, use Keruilai 's online calculation tool to choose the cooling fan that suits you.

　　7. How to install Keruilai air cooler?

　　Keruilai 's cooling fans are quick and easy to install. First take the air cooler out of the box and tear off the protective packaging. Depending on the model, place the air cooler in front of a window or on a cart and carefully insert the water hose into the float valve. When filling the water tank, the air cooler cannot be connected to power and should remain turned off. Then plug the cooling fan into a nearby electrical outlet and turn it on. Press the cooling button and wait for 1 minute until the water soaks into the wet curtain and you can feel the refreshing cool breeze. For optimal cooling performance, open all doors and windows.

　　8. Can the Keruilai air cooler/cooling fan be connected to an inverter to operate?

　　Can. All Keruilai air coolers/cooling fans can be connected to frequency converters. Please make sure your frequency converter can output sine waves properly. The standard electrical type supplied by all utilities is sine wave and all air coolers/cooling fans and most frequency converters work to this standard.

　　9. How to dispose of old Keruilai industrial air cooler

　　Keruilai industrial air coolers are innovative electrical equipment and should not be disposed of alongside household waste. Recycling air coolers/cooling fans is an effective way to prevent them from causing harm to human health or the environment. If you need to dispose of the air cooler/cooling fan, please contact the local government agency or the nearest Keruilai dealer for detailed information on how to dispose of the air cooler/cooling fan.
