Are evaporative air coolers suitable for large spaces?

Evaporative air coolers are very suitable for cooling large-space environments, and have become a highly cost-effective cooling solution in places such as factories, warehouses, gymnasiums, greenhouses, and breeding farms. Compared with traditional air conditioning systems, evaporative air coolers have the advantages of large coverage area, low operating cost, and simultaneous ventilation and air exchange, and are especially suitable for open or semi-open large-space environments.

Core demands of cooling systems in large-space environments

Large spaces generally have the following characteristics: large spatial volume, dense personnel or dense equipment, concentrated heat sources, high ventilation demand, high floor height, complex airflow organization, and poor airtightness.

Traditional air conditioning systems in such environments often have problems such as: high construction cost, high energy consumption, low cooling efficiency, and high maintenance cost, while evaporative air coolers exactly match these environmental characteristics.

Advantages of the working principle of evaporative air coolers

Evaporative air coolers cool through the principle of water evaporation and heat absorption: air passes through the cooling pad, water evaporates and absorbs heat, air temperature decreases, and at the same time fresh air replacement is realized, achieving the comprehensive effect of cooling + ventilation + air exchange + oxygen increase, which is very suitable for large-space environments.

Industrial-grade evaporative air coolers single-unit coverage capacity： Conventional models: 100–300㎡、Large industrial models: 300–800㎡，System combination solutions: can cover tens of thousands of square meters of space. Through multi-unit linkage control and air duct systems, large-area centralized cooling can be achieved.

Operating cost is far lower than traditional air conditioning systems

More reasonable airflow organization in large spaces

Evaporative air coolers have strong air supply capability: large air volume output, long-distance air supply, multi-point layout, directional airflow organization, and zoned cooling, effectively solving the problem of “uneven cooling” in large spaces.

Health advantages of simultaneous ventilation and air exchange,Large-space ventilation problems include: air stagnation, odor accumulation, accumulation of harmful gases, and retention of hot and humid air. Evaporative air coolers achieve continuous ventilation and air exchange while cooling, improve air quality, and form a healthy working environment.

Evaporative air coolers are widely used in: industrial plants, warehousing and logistics centers, gymnasiums, exhibition centers, commercial malls, greenhouses, livestock breeding farms, station waiting halls, airport halls, and industrial workshops. The common characteristics of these spaces are large space + strong openness + high ventilation demand.

Advantages compared with traditional air conditioning systems

Not all large spaces are suitable for evaporative air coolers, for example: cooling effect is limited in high-humidity areas, enclosed spaces need to be combined with exhaust systems, places with high requirements for precise constant temperature control are not suitable, and the effect is not obvious in low-temperature environments, so comprehensive evaluation must be carried out in combination with environmental conditions.

Selection and system design suggestions: Select air volume parameters according to space volume, reasonably arrange air supply and exhaust paths, realize zoned control through multi-unit linkage, carry out system design in combination with humidity environment, and support air duct systems to improve efficiency.

Evaporative air coolers are not only suitable for large spaces, but in open, semi-open, and high-ventilation-demand environments, they are one of the most cost-effective cooling solutions at present. Their advantages are not in the “extreme cooling temperature difference”, but in large-area coverage capability, low-energy-consumption operation mode, simultaneous ventilation and air exchange capability, and system-level economy.
