With the increasing frequency of hot weather, evaporative air coolers have become a popular cooling option for homes and commercial places due to their energy-saving, environmentally friendly, low-cost and high-efficiency characteristics. But faced with a wide range of products on the market, how to choose the most suitable model?

This article will deeply analyze the working principle and core purchasing criteria of evaporative air coolers, and recommend high-quality models suitable for multiple scenarios. At the end of the article, we will also introduce Wanjiada’s customized services and advantages to help you easily purchase cost-effective cooling equipment.

Evaporative Air Coolers: Principles and Advantages

Evaporative air coolers cool down by the principle of water evaporation and heat absorption: external hot air is sucked into the equipment, passes through a moist cooling medium (such as a honeycomb filter or cooling pad), and the water evaporates to take away the heat, and finally outputs a cool and moist airflow. Compared with air conditioners, its advantages include:

• Energy saving and environmental protection: The power consumption is only 1/10 of that of traditional air conditioners, and no refrigerant is required, with zero carbon emissions.
• Low cost: The equipment purchase and maintenance costs are lower, especially suitable for large open spaces.
• Ventilation: Keep doors and windows open to avoid air pollution in closed spaces.

However, its cooling effect is greatly affected by the ambient humidity. It performs best in dry climates (humidity below 60%) and needs to be selected with caution in high humidity areas.

How to Choose the Best Evaporative Air Cooler?

• Small space (<30㎡): such as bedrooms and offices, it is recommended to use a portable model with a water tank capacity of 1-6L and a CFM (air volume) of 200-500 (such as WJD980F-3M).
• Medium and large space (50-200㎡): such as living rooms and warehouses, it is necessary to choose a model with a CFM of more than 1000 and a water tank of 10-30L (such as WJD2800F-2Z).
• Industrial or outdoor scenes: high CFM (such as WJD8000F-2Z) and continuous water supply function (support external water pipe) are required.
