Cooling principle of plastic evaporative cooling pad

First, the definition and structure of plastic evaporative cooling pad
The plastic evaporative cooling pad is mainly made of plastic material and has a porous structure, which can achieve the effect of cooling and ventilation through the evaporation of water. It is usually installed at the inlet of the ventilation equipment and is used in conjunction with the fan to form a complete cooling system.
Second, the cooling and ventilation principle of plastic evaporative cooling pad
Evaporative cooling: When hot outdoor air passes through the water curtain, the water molecules on the water curtain will absorb the heat in the air and evaporate, thereby reducing the temperature of the air. This process is similar to evaporative cooling in nature.
Cooling pad effect: The porous structure of the cooling pad can increase the contact area between air and water and improve the evaporation efficiency. At the same time, the cooling pad can also play a role in humidifying the air, helping to improve the indoor environment.
Negative pressure ventilation: When used in conjunction with the fan, the plastic evaporative cooling pad can form a negative pressure environment, attracting outdoor air through the cooling pad into the room to achieve forced ventilation. This ventilation method not only has a good cooling pad effect, but also can effectively eliminate harmful gases and dust in the room.
