Evaporative cooling pads are devices that use the principle of water evaporation to absorb heat to reduce air temperature.

December 18, 2024

1. Working principle
The working principle of evaporative cooling pads is based on the natural phenomenon of “water evaporation absorbs heat”. When hot air passes through a moist evaporative cooling pad, the moisture on the pad evaporates and absorbs heat from the air, thereby reducing the temperature of the air. At the same time, due to the evaporation effect, the water vapor content in the air increases and the humidity rises accordingly.

2. Structural characteristics
Evaporative cooling pads are usually made of special paper with a honeycomb-like structure to increase the evaporation area and improve the cooling efficiency. Water falls from the top under the action of gravity and forms a water film on the corrugated surface of the evaporative pad paper. When the air flows quickly through the cooling pad, the water in the water film absorbs heat from the air and evaporates, taking away a large amount of latent heat, thereby achieving the purpose of cooling.

3. Application places
Evaporative cooling pads are widely used in industrial plants, greenhouses, animal husbandry, supermarkets, offices, workshops and other places that require ventilation and cooling. It can not only provide effective cooling effect, but also increase air humidity and improve indoor air quality.

4. Advantages and characteristics
Energy-saving: The power consumption of the evaporative cooling pad is only about one-tenth of that of traditional air conditioners, which greatly reduces energy consumption and electricity bills.
Environmental protection and health: The evaporative cooling pad does not produce harmful chemicals such as Freon, and has no pollution or harm to the environment. At the same time, it can also produce negative ion oxygen, increase the oxygen content in the air, and improve indoor air quality.
Low noise: The evaporative cooling pad does not have the compressor and condenser of traditional air conditioners, so the noise is very small, which is suitable for places that require a quiet environment.
Easy to maintain: The wet pad of the evaporative cooling pad is the only part of the cooler that needs maintenance, which is very convenient.

5. Precautions for use
During use, do not let the wet pad be too wet, otherwise it will affect the cooling effect.
When replacing the wet pad, you need to clean the inside of the cooler at the same time to keep it clean and hygienic.
If it is not used for a long time, you need to drain the water in the cooler to prevent bacteria and odor.
