Products Description

Cooling principle

When the cooler is operating, water is pushed from the water tank to the water distributor, where it is equally distributed to the evaporative cooling pads before returning to the tank. Prior to being delivered to the user space, the outdoor hot air is drawn via the wet cooling pads, filtered, and has its temperature decreased.

How does evaporative air cooler work?

Fresh outdoor air is continuously brought into the indoor room through the air duct and air supply outlets after being filtered and cooled by an evaporative air cooler. The indoor environment will be in a positive pressure state due to the constant flow of fresh air, which will cause the initial hot air that included odor and dust to be expelled out of the space and leave behind a cool, ventilated, tidy, and comfortable environment. For any evaporative air conditioning system to operate satisfactorily, a suitable exhaust area and an efficient exhaust are necessary.

Supply Air Temperature

The "dryness" of the outside air determines the supply air temperature. The temperature of the web bulb decreases as the outside air becomes dryer. The ability to reduce temperature is increased.
When the outside air is hot and dry, evaporative cooling performs at its optimum. For information on temperature drop (supplied air temperature with air cooler) under various humidity and temperature circumstances, see the datasheet below.
The secondary cooling effect known as the "wind-chill effect" occurs when air moves over human skin, creating an effect like to that produced by a fan and making it feel cooler. The Supply Air Temperature and Air Velocity both affect the Wind-Chill Effect.


Why Evaporative Air cooler?



A portable air cooling unit is a compact, lightweight system that cools indoor spaces without requiring a permanent installation.

Portable air cooling units work by pulling in hot air and passing it through a cooling pad. The cool air is then blown back out into the room, reducing the temperature and increasing humidity.

The size of the room that a portable air cooling unit can cool depends on the model. Typically, portable air coolers are designed for smaller rooms, such as bedrooms or offices.

The power consumption of a portable air cooling unit varies depending on the model and settings. However, compared to air conditioning units, portable air coolers are generally more energy-efficient.

The noise level of a portable air cooling unit depends on the model. However, most portable air coolers operate quietly, making them suitable for use in bedrooms and other quiet spaces.

Portable air cooling units offer several benefits, including cost-effectiveness, portability, energy efficiency, and increased humidity, which can be beneficial for people with respiratory issues.

To clean and maintain your portable air cooling unit, unplug it and use a clean, damp cloth to wipe down the exterior and interior of the unit. It's also recommended to replace the cooling pad regularly.

Portable air cooling units are designed for indoor use. Using them outdoors can result in insufficient cooling and damage to the components.
