What is the best climate for evaporative cooling?
Evaporative cooling relies on the basic principles of evaporation, where warm or hot air passes through water which evaporates to lower the air temperature. To read more about the science behind evaporative cooling, click here.
For evaporation to take place, humidity needs to be below 100%, so the air can begin to absorb water. Air can hold a certain amount of water vapour, and the degree of water absorption will depend on how much it is already ‘holding’.
In humid climates, Breezair can provide comfort by increasing airflow. Breezair units include a Hushpower® motor and a unique centrifugal fan to increase the flow of air via ducts throughout the building.
Evaporative cooling works especially well in areas that record mostly hot and dry conditions, as the humidity in the air is typically low.
In climates that have high humidity and high temperature simultaneously, indirect evaporative cooling may be the most effective solution. Indirect evaporative cooling is a technology which uses an indirect evaporative heat transfer core that provides hyper-efficient cooling of outside air. Indirect evaporative cooling delivers temperatures which are comparable to refrigerated air conditioning but at dramatically reduced operating costs – it also adds no moisture to the air supply, making it ideal for more humid climates.
Seeley International manufactures a range of indirect evaporative cooling products through our global brands, Climate Wizard and Coolerado.
