High-efficiency air coolers: ideal for industrial and commercial refrigeration systems

What is the main working principle of air coolers?
An air cooler is a device that cools the air through the principle of evaporative cooling and is widely used in industrial, commercial and domestic environments. Its main working principle is to use the evaporation of water to absorb heat, thereby reducing the air temperature and providing a cool air environment.

An air cooler, also known as an evaporative cooler, is a cooling device based on the principle of natural evaporative cooling. Unlike traditional air conditioning systems, it does not rely on refrigerants, but achieves cooling effects through the evaporation of water. An air cooler usually consists of a water tank, a cooling pad, a water pump and a fan. It blows hot air through the moist cooling pad to evaporate the water and take away the heat, thereby reducing the air temperature. This device performs particularly well in dry and hot climates, and can effectively reduce indoor temperatures while increasing air humidity to make the environment more comfortable.

The main working principle of air coolers
Water preparation: The air cooler requires a water tank filled with clean water. The water is delivered to the cooling pad through a water pump.
Air introduction: Hot air enters from the air inlet of the device, and when passing through the cooling pad, the air comes into contact with the moisture on the cooling pad.
Evaporative cooling: Moisture evaporates during the air flow, and the evaporation process absorbs heat from the air, thereby reducing the air temperature.
Air output: The cooled air is blown out through the fan and enters the indoor space to provide cool air for the room.

Structure and components of air coolers

Water tank: Used to store cooling water to ensure that the cooling pad is continuously moistened.
Cooling pad: Usually made of porous materials such as wood fiber or plastic, it is used to absorb moisture and promote evaporation.
Water pump: Pumps water from the water tank to the cooling pad to ensure the continuous cooling process.
Fan: Accelerates air flow, improves cooling efficiency, and blows the cooled air into the room.
Filter: Some models are equipped with air filters to filter dust particles and improve air quality.

What are the energy-saving advantages of air coolers?
1. Low energy consumption in operation

Air coolers achieve cooling through the evaporation of water. During its operation, only a small amount of electricity is required to drive the fan and water pump, and the overall energy consumption is much lower than that of traditional air conditioning systems. For example, in an environment of 35°C, the maximum power of the air cooler in the dual forced cooling mode is only about 900W, while the power of traditional air conditioners is usually between 2000W-3000W. In addition, the energy consumption of air coolers is only 1/8 to 1/10 of that of traditional air conditioners.

2. No water resources required

Compared with traditional water cooling systems, air coolers do not rely on cooling water, so a lot of water resources are saved. This is particularly important in water-scarce areas and helps to alleviate the problem of water shortage. At the same time, since there is no need for a cooling water circulation system, the infrastructure construction cost of air coolers is lower.

3. Low maintenance cost

The structure of the air cooler is relatively simple, and there is no complex cooling water circulation system, so maintenance and maintenance are more convenient and quick. Its maintenance cost is only 20%-30% of that of the water cooling system. In addition, the components of the air cooler, such as fins and fans, are less corrosive and have a longer service life.

4. Natural cooling capacity
Even in the case of a power outage of the fan, the air cooler can still maintain 30%-40% of its natural cooling capacity, which provides additional protection in emergency situations. At the same time, the cooling effect of the air cooler is particularly significant in a dry environment, which can effectively reduce the air temperature and increase the humidity.

5. Environmental protection and energy saving
The air cooler does not use refrigerants, avoids the emission of harmful substances such as Freon, and is environmentally friendly. In addition, it produces almost no thermal and chemical pollution during operation, which meets the requirements of green buildings and sustainable development.

6. Simple system construction
The system structure of the air cooler is relatively simple, without the need for a complex cooling water circulation system, which reduces the equipment footprint and construction difficulty, and reduces the overall cost. At the same time, its installation and maintenance operations are simple and suitable for a variety of application scenarios.

What should be paid attention to in the maintenance and care of air coolers?
The maintenance and care of air coolers is key to ensuring their efficient operation and extended service life. Here are the main things to pay attention to in maintenance and care:

Regular cleaning
Clean the water tank, filter and cooling pad of the air cooler regularly to prevent dust, bacteria and mineral deposits.
Empty and clean the water tank at least once a week, using mild soap and warm water, and rinse thoroughly to remove residue.
Check the cooling pad regularly for signs of wear or mineral buildup, and clean it gently by rinsing it with water or soaking it in a vinegar solution if necessary.

Check the water level and water quality
Maintain the water level in the water tank between the minimum and maximum water levels, and use clean filtered water to prevent mineral accumulation and other contaminants that can harm the equipment.
If the water is hard or high in minerals, use a water softener or descaling agent regularly.

Check the fan and motor
Lubricate the fan motor regularly, at least once a year, and use a few drops of oil to coat the motor bearings to prevent noise and malfunctions.
Check the fan belt for wear or damage, and replace it regularly to avoid fan failure and equipment damage.
