How Airius Air Cooling Fans work is through the use of our world leading and patented columnar laminar flow and venturi vent technology, which provides large amounts of air movement using very low amounts of energy for cooling your space in summer. Great for non-conditioned sports halls, offices, warehouses, gymnasiums or schools etc.
Also, the use of air cooling fans in all building types will save large amounts of energy when used in conjunction with an air conditioning system.
It is important to also note when using air conditioning for cooling or heating a building, the air conditioning systems must constantly over deliver to satisfy the thermostat that sits between the cool air on the floor and the hot air under the ceiling. That results in large amounts of wasted energy.
Airius Air Cooling Fans move cool air gently (or strongly as required) and effectively around the space in summer, satisfying the thermostat much quicker and therefore turning the compressor off for longer, or, in non-air-conditioned spaces, will provide strong air movement for summer cooling.
In air-conditioned spaces, the cold air on the floor is bought up to where it is needed, and the hot air is not allowed to build up in the zone under the ceiling where the return air grilles are located, significantly reducing the return air temperature.
A great example of this is in a large, big box retail store in Robina, QLD, where the return air temperature back to the chiller was reduced by 4-5 Deg. C. This reduced the cooling loads and saved 30% of their air conditioning energy consumption, while optimising comfort.
These types of energy savings have been independent modelled too and that computerised modelling in the Australian climate indicates savings of 10-30% are achievable on-air conditioning cooling energy without changing the thermostat etc.
In addition, the use of the fans improves thermal comfort. That is validated by large amounts of empirical research and evidence. (See Airius Blogs)
If you also increase the thermostat set point in summer, (for example from say 22.5 -26 Deg. C.) you can obtain even further energy savings and comfort is not affected as you are using the cooling effect of the circulated air to substitute for the supply of some conditioned air. – see below.
