A Based on used area, airflow requirements, and noise requirements:
For 10-20 square meters, choose an air cooler with airflow of less than 2000 m³/h.
For 20-40 square meters, choose an air cooler with airflow of less than 3000-4000 m³/h.
For 40-60 square meters, choose an air cooler with airflow of less than 4000-6000 m³/h.
For 60-80 square meters, choose an air cooler with airflow of less than 6000-8000 m³/h.
For 80-150 square meters, choose an air cooler with an airflow of less than 8000-18000 m³/h.
For 150 square meters and above, choose an air cooler with an airflow of 18000-22000 m³/h, or use multiple units with an airflow of 5000-8000 m³/h.
Air coolers with airflows below m³/h. For areas with large crowds or high heat generation, increase the number of units accordingly. For no high noise requirements, choose an axial flow air cooler. For low noise requirements, choose centrifugal air cooler.
