What are the Types of Evaporative Air Coolers?

Evaporative air coolers are mainly divided into three categories based on their application scenarios and installation methods: portable, roof/sidewall fixed, and centrifugal. This type of equipment utilizes the physical principle of water evaporation absorbing heat to cool the room, effectively reducing indoor temperature while also providing ventilation and humidification.

Main Classifications of Evaporative Air Coolers

Understanding the characteristics of different types is key to ensuring effective cooling when choosing an evaporative air cooler. The following are the three main types currently on the market:

1. Portable Evaporative Air Cooler (Home/Commercial)

These devices are relatively small and equipped with casters for easy portability.

Suitable Scenarios: Living rooms, offices, outdoor dining areas, or small repair shops.

Features: No professional installation required; simply fill with water and connect to a power source for immediate use. Operation is very simple.

2. Fixed Axial Air Cooler (Industrial/Large Area Dedicated)

This is the most common type of evaporative air cooler used in factory workshops and logistics warehouses. It is typically installed on the roof or sidewall, delivering cool air into the room through ductwork.

Applicable Scenarios: Machinery manufacturing plants, garment factories, greenhouses, and large sports stadiums.

Features: Large air volume and wide coverage, enabling whole-area ventilation and significantly reducing the "stuffy" feeling in large spaces.

3. Centrifugal Evaporative Air Cooler

Unlike common axial fans, centrifugal models have higher air pressure.

Applicable Scenarios: Complex building structures requiring long-distance air duct delivery.

Features: Relatively quiet operation and strong air penetration, suitable for locations with special requirements for quiet operation and air delivery distance.

Why Choose an Evaporative Air Cooler?

Compared to traditional compressor air conditioners, evaporative air coolers are becoming increasingly popular in modern industrial and residential environments, mainly due to:

Energy Saving and Environmental Protection: Consumes only about 1/8 of the power of traditional air conditioners and does not use Freon, making it environmentally friendly.

Fresh Air: Employs an open-type air supply system, continuously introducing fresh outdoor air and expelling stale air, maintaining sufficient oxygen levels indoors.

Significant Cooling: In hot, dry regions, temperature reduction can reach 5-12°C.
