99 Bikes needed to refurbish their Air Conditioning and electrical works in their new store in Perth, Australia. Their plan was to remove the ceiling and ductwork and approached Airius for a solution to mix and distribute the conditioned air around the space.
Airius proposed the use of 7 x Pearl Series fans with speed controller, positioned to suit the customer’s requirements and ensure efficient circulation, balancing and distribution. Across the summer of 2018-19 the solution has been a great success.
99 Bikes is an Australian wide business that specialises in
the sales and maintenance of all types of pushbikes or cycles.
Gareth Halliday, General Manager at ECO – Climate Solutions,
was contacted by 99 Bikes who are a regular client of theirs, to design and
install an electrical and mechanical fit project for their new Belmont store
and quote to achieve that aim.
Eco Climate solutions specialise in resource efficient air
conditioning systems and energy efficiency products. After having read an
Airius publication about the efficiency of the Airius fans as a low-cost
substitute for air conditioning ductwork, they approached Airius to work up a
The store is approximately 300 sq. metres in size and has a
4.5 metres high ceiling. Located in Perth, high temperature summer cooling as
well as some winter heating efficiencies were key design criteria.
As the original ceiling was being removed to open up the
space, Gareth designed a system to also remove all of the old supply and return
ductwork from the four existing 14kW Panasonic ducted reverse cycle air
conditioning systems. Eco -Climate Solutions (ECS) then simply supplied
conditioned air out of the horizontal registers.
Four Pearl Airius fans were located horizontally at the
discharge points of the ducted units for air circulation and three more Airius
fans were installed vertically around the space for de-stratification and air
mixing, suspended just off the roof/ceiling to ensure there was adequate summer
and winter air mixing throughout the space.
This install took place in August 2018 and right across the
2018-2019 hot summer period, the client has been extremely happy with the
thermal comfort in the store.
Gareth Halliday from ECS has advised they are also very
happy with the result and are looking to undertake some detailed energy
modelling of the facility over the next few months to understand the energy savings
this type of innovative installation has created.
Gareth advises though, that significant energy and cost
savings have certainly been achieved with the removal/ non replacement of
ductwork and the reduced static pressure issues combined with a substantial
reduction in cap ex, materials, maintenance, coordination, commissioning and
plant size expenditure.
Additionally, new opportunities arise for architects due to
the open uncluttered ceilings and increased floor to ceiling height that offer
even more opportunities from this type of install.
The overall result has been a success and ECS are looking to
utilise this unique solution in further installations as the opportunity
