The temperature of the air that the evaporative cooling system creates is reliant on the outside temperature and humidity levels. Generally speaking, there should always be a drop in temperature
Low running costs
Compared to refrigerated cooling systems, evaporative cooling systems can be up to 80% cheaper to run. Evaporative coolers will also cool the entire home or building it is installed in, while other forms of cooling will only cool specific zones within the building.
The pads that the warm air is drawn through will filter out any dust particles. This leaves the air that enters the home very clean and clear of dust, allergens and insects.
Can be used in large open spaces
Evaporative cooling forces warm air out of the room, replacing it with the cooled air. This means that the coolers will work in large open spaces, where a conventional air conditioner would not work as well.
