The air cooler can be installed on the wall, the roof or the outdoor floor. At this time, we should avoid the air duct being too long, generally 15-20m in length, and try to reduce the elbow of the air duct or not.

When the main engine of the cooling fan is running, it is necessary to open the door or window of the area for ventilation. If there are not enough doors and windows, the exhaust fan shall be installed and the exhaust volume shall be 80% of the total air supply volume of the environmental protection air conditioner.

The main frame of the cooling fan needs to be welded with steel structure, and its structure is required to support twice the weight of the whole body and maintenance personnel.

The ventilation frequency of general air cooler is as follows:

General environment requires 25-30 breaths per hour; crowded public places require 30-40 breaths per hour; production workshops with heating equipment require 50-60 breaths per hour; in humid southern areas, the number of breaths should be appropriately increased, while in hot and dry northern areas, the number of breaths can be appropriately reduced.
