Air conditioners are more expensive than air coolers and they are also more environmentally friendly. These air coolers draw cool air from outside and provide cooling air inside the room. They do not require refrigerants or any other chemicals.
Evaporative cooling is another principle behind air cooling systems. The cooler pulls hot air from outside and then runs it through the cooling media. These cooling media can be either wet filter pads or cellulose cooling pads. The air temperature is then lowered and distributed throughout the room using a fan.
Initially, water is stored in the air cooling unit. The latent heat of evaporated water causes the hot air to pass over cooling pads that are sprayed with water. The evaporated water absorbs the heat from the hot outside air and cools it down. The cooler’s exhaust fan distributes the cool air throughout the room, which results in a decrease in temperature.
High humidity places, however, don’t evaporate water as quickly. Due to high levels of moisture in the atmosphere, the saturation level is reached and you can feel the water droplets produced by the cooler. Air coolers work best in dry climates that have less humidity.
Evaporative coolers increase the humidity in humid areas. This causes the room to feel stuffy, hot, and uncomfortable. Too much humidity in the home can lead to mold growth and condensation in the walls. This can cause structural damage or wood rot. As well as respiratory problems, too much humidity can cause mold growth.
Humidity Levels Required For Air Cooler Operation
- Desert coolers or evaporation are most effective in areas where the relative humidity is low. This makes them ideal for dry climates.
- The internal humidity levels rise significantly during evaporative cooling.
- This is why it’s so effective in dry areas, where the cool moist air rehydrates the skin.
- The air temperature, or the “dry bulb temperature”, can be used to predict the humidity needed for air coolers.
- “Wet bulb temperature” refers to the humidity. This shows how cooling is affected by humidity.
- The relative humidity also measures how much air is saturated with water. This percentage is calculated by taking into account the amount and type of moisture in the air. It then compares that to the maximum water content at the temperature.
- The air cooling system can reduce the temperature by up to 74° Fahrenheit at a temperature of 90° Fahrenheit and relative humidity of 30%.
How To Choose The Right Size Of Swamp Cooler?
The cooling power of an industrial air conditioner is determined by how much airflow it can produce. These coolers are classified according to their airflow. They are usually rated in cubic meters per hour (CMH), cubic meters per minute (CMM), or cubic feet per second (CFM). This measurement measures how much air an air cooler can move or pump per unit of time.
Your machine choice will be determined by the size of the cooling system you use. A machine calibration should be approximately half the area of your target space. This is an approximate calculation for enclosed spaces such as a garage, shed, patio, tent, or outdoor space.
The cooler you need to cool your target area will depend on how small it is. It is more difficult to calculate airflow in open areas.
