TESCO IMPLEMENTS COSAF’S Air2O SOLUTION AMID PLANS TO REDUCE ENERGY USAGE BY AS MUCH AS 80%

Cosaf, the expert in leading-edge
heating, ventilation and air conditioning (HVAC) systems for the retail,
pharmaceutical and grocery sectors, has today announced a ground-breaking
partnership with Tesco, the UK’s largest grocery retailer. Cosaf will
upgrade Tesco’s in-store cooling systems by implementing its innovative
Air2O IDEC evaporative cooling air conditioning technology.
The partnership, which is set to position Tesco as the UK’s most
environmentally efficient grocery retailer by 2025, will lower the energy
usage of Tesco’s environmental systems by 80%. It will significantly
reduce its capital, running, and maintenance costs by completely replacing
all compressor based cooling systems from their comfort cooling air handling
units (AHUs) with Air2O innovative IDEC air conditioning systems. It will
also help the retailer to comply with its internal governance and
environmental pledges, and reduce its reliance on DX cooling.
It is essential for major grocery retailers to use refrigerant cooling
systems to maintain produce fridges and freezers. However, many are still
using outdated and inefficient F-GAS legacy systems (or CO2) to cool their
stores. These are expensive in upfront cost, service and maintenance and use
large amounts of CFC, GWP and HFC gases; all of which are widely recognised
as harmful to the environment and, worse, are unnecessary for environment
cooling.
Cosaf is committed to reducing energy inefficient systems in any application
of comfort cooling. It’s Air2O system provides the solution to this
industry-wide problem and ongoing challenge for Tesco by using an
environmentally-friendly combination of direct and indirect evaporation
cooling, which eliminates harmful gases. It also utilises IDEC technology to
eliminate stale air recycling, delivering 100% hygienic fresh air with no
harmful gases for Tesco’s produce, employees and customers.
Karl Sullivan, Managing Director, Cosaf Environments, said: “Cosaf is
proud to partner with Tesco to provide real energy savings through our
practical design expertise and innovative technologies. Tesco’s deployment
of Air2O is such a significant upgrade process. It’s IDEC capability is an
effective solution to Tesco’s F-GAS challenge and shows that it is
possible for retailers to move on from old habits, while strengthening our
belief in sustainable solutions to every day HVAC problems.”
As one of the world’s largest retailers with 476,000 colleagues and
millions of customers per week, Tesco needed to build confidence in Cosaf
over a 5-year period of significant due diligence. This was achieved when,
in December 2016, Tesco agreed to install an Air2O system in its
Henley-on-Thames superstore for a live test phase.
Despite an unexpected heat wave in June 2017, which included the hottest 5
consecutive days in 25 years, and the hottest individual day in 15 years,
Air2O performed beyond all expectation and successfully delivered cooled
outside air to the sales floor’s AHU. After receiving positive initial
feedback, Tesco then extended its relationship with Cosaf by ordering
further Air2O units for its distribution depot in Reading, which are now
fully installed and operational.
As the next generation in air conditioning technology, Air2O can uniquely
hybridise and incorporate traditional DX or chilled water cooling to adapt
intuitively to its environment. This flexibility was important when adapting
to the different challenges presented by Tesco’s distribution centres and
superstore layouts, with variable air temperatures that are directly and
indirectly affected by large chillers and refrigerants.
Roger Oliver, HVAC Engineering Manager, Tesco, said: ‘’We are delighted
to partner with Cosaf for the implementation of Air2O in both our
superstores and distribution centres. As one of the world’s largest
retailers, we are committed to delivering the most efficient and healthy
environments for our staff, customers and stakeholders. As such, we required
an alternative cooling solution that wouldn’t rely on refrigerant gas, and
would fit within our existing AHU model. Cosaf worked closely with our AHU
supplier to deliver a solution that effectively aligned with these
parameters. Cosaf’s established reputation for unparalleled customer
service and unique capabilities gives us confidence that our partnership
will continue to successfully advance our goals in this field.’’
Air2O is a world leader in managing unpredictable and varying climate
conditions. With technology developed in California and refined in the
extreme climates of Arizona, the middle east and Australia; Air2O is
perfectly suited to thrive in the UK’s moderate climate.
