How do they work?

Airius Air Pear fans  are a simple solution to a simple but expensive to fix problem. That is one of their great attributes. They are designed to move air in a non turbulent laminar flow in any chosen direction. In cold climates  or when heating is required they are used to direct the hot air rising to under the ceiling space  back down to the floor area where the heat is required. This is certainly a great bonus to climates  found in New Zealand and colder parts of Australia as well as any facility requiring heating which can also be in Brisbane during winter the savings in heating bills by capturing the wasted heat sitting under the ceiling are proven and shown to be very significant.

In the Australian climate though the key issue is cooling and the cooling  mode  used in air  conditioning systems is the one that uses the most energy.

In any air conditioning system the component that uses the most energy is the fans- the Air Handling Units, the duct fans and related air pushing or circulation infrastructure. The next most energy consuming component is the chiller. (See chart below) If you can reduce both AHU and related chiller use by reducing their loads then significantly  large energy savings are applicable to your air conditioning system.

Often the AHU is located far way from the area requiring conditioning and the cold heavy air has to be forced through and around ducts. into registers at the correct approach angle out of registers in a specific pattern (correct register design and back pressure required to suit the space and temperature range    and then there is really only pressure caused by density differences and air flow pattern out of the register that encourages that cold air to settle to  the floor.It then  has to circulate around the room otherwise    cold spots are created and internal  partitions and shelving and a range of other restrictions impede that flow.

The thermostat  located at 1.5 or 1.8 metres above floor level  is not reading this pool of cold air sitting at floor level so keeps asking for more cold air from the system. This is a key are of waste in air conditioning systems

Remember  all the time the air is being forces from an AHU often floors away.

In addition the cool air has to come in via ducts that are located in hot ceilings which makes them loose   cooling energy  then the less cold air has to fight its way down to the floor via the hot air sitting up at the ceiling. In addition due to the COANDA effect some of the air discharging from the registers flows across the ceilings and goes back out directly via the return air duct resulting in wasted energy.

All of these encourage more energy use as the  AHU and rated chilling / refrigeration  equipment is trying to compensate  The the cold air sits down  the floor below the thermostat so the thermostat is not being satisfied as efficiently and quickly as it could be. The dense cold air once settled is also very hard to move around especially for an AHU or duct  or VAV register fans that arent designed to move air very efficiently and are located  many metres away form the spot in question inside a duct.

This is where the Airius Air Pear air circulation  fans come in  in the Australian  climate.

Sitting inside the room and located up at the ceiling they grab the cool air as it comes out of the registers and force it down to  the ground much quicker than if it is just falling.The units set up a circulation effect and the movement  of the air hitting the floor and then returning back up to the ceiling again entrains all the air around it and sets up a movement of air that ensures the air in the space is circulated evenly and quickly  but without disturbing  the users in the space.

The great thing now is the thermostat sitting at 1.5 metres up on the wall is very quickly satisfied telling the AHU and chillers to shut off a lot more often than if left to their own devices.-The system works  much less and the energy used is significantly less as well as the maintenance on the system being reduced as it just doesnt  work so hard. All the ducts and AHU and refrigeration  equipment  is left in many cases redundant, switching on only as required as the efficiency of the system is optimised.

As the Airius Thermal equalisation fans run all the time and use very  low amounts of power the hot air in the space never has a chance to rise to the top therefore the initial  fear expressed by many engineers , why would I bring the hot air down in summer is never realised.The internal temperature is equalised meaning no hot air sits up there.

In order to prove the point please see our  case study undertaken by a major retailer over this very hot 2012-13 summer.

In this retail trial  this  theory is proven (as it has been in the hot eastern and inner states in the USA) where the hot summers of 32 Deg C Plus have shown significant energy savings in conditioned spaces as we have seen achieved here in the major retailers store in Melbourne.

Maps of the chiller performance curve and energy  monitoring  undertaken by the customer  for example show that on 32.5 Deg Days plus the chiller is working significantly  less than before  the Air Pears fans were installed.

Overall energy  savings of 30% were achieved on a regular basis.

The ability to mover the air in a laminar flow and non turbulently using very low amounts of power are key to the patent in the Airius Air Pear  units.

Typical ceiling and other types of fans move the air in a circular motion wasting energy, minimising  penetration and using a lot more power while creating much more tubulence.

The patented stator  design in the Airius Air Pear fans achieved after years of testing and design improvement straightens the air flow making it travel long distances without impacting in an negative way.The surrounding air is entrained into the flow so that the whole room is gently moving ensuring temperatures  are equalised.

The use of our fans in  so many applications over seas as a simple and easy retrofit as well as  new solution has come after many other alternatives have been tried and have failed.Trying to design the inherent problems noted above  out of air conditioning systems is very expensive,time consuming and rarely effective.

The savings a significant  when using our systems hence the very quick paybacks  If you are using many fans then your payback will be proportionally the same.

If you see our videos on the home page you will see examples of how the systems work, how ceiling fans dont do the same job and how the air in the space is equalised.
