Compared with ordinary coolers, how much higher is the cooling efficiency of evaporative air coolers with cooling pads?

Evaporative air coolers achieve cooling through the principle of water evaporation and heat absorption. The material and structure of the cooling pad, its core component, directly affect the cooling efficiency. For example, an industrial-grade evaporative cooling pad with a corrosion-resistant honeycomb structure, combined with a reasonably designed air duct system, can achieve a cooling efficiency of about 90%. This high-efficiency cooling pad increases the contact area between water and air and accelerates water evaporation, thereby improving the overall cooling effect.

Compared with ordinary coolers, evaporative air coolers can achieve more significant cooling effects at the same energy consumption. Ordinary coolers usually rely on air cooling or simple water cooling technology, while evaporative coolers absorb a large amount of latent heat through the water evaporation process, and the cooling efficiency is particularly improved in dry environments. For example, in areas with low humidity, evaporative coolers can use the difference in ambient humidity to accelerate evaporation, and the cooling range can reach 8-12℃, while ordinary coolers may only achieve a cooling of 3-5℃.

In addition, the cooling efficiency of the evaporative air cooler is also affected by factors such as the cooling pad material, wind speed, and air inlet temperature. High-quality cooling pads can improve the uniform distribution and evaporation rate of moisture by optimizing fiber density and pore structure.

Increasing the air flow rate with an efficient fan can further enhance the heat exchange efficiency. In industrial scenarios, evaporative air coolers with cooling pads can achieve rapid temperature reduction in workshops within 10 minutes by reasonably designing the air supply distance and coverage range, while ordinary coolers may take longer to achieve the same effect.
