WR2 Helps Logistics Centre Realise Green
Ambitions
A pioneering British company has been showing
just how sustainable buildings can be with its new International
Logistics Centre in Southend.
Olympus KeyMed’s 3,400m² centre is unique for its type in the UK
because it combines high finish levels with a sustainable approach
that uses a combination of green systems for significantly better
energy efficiency than an equivalent conventional facility.
At the heart of the eco-friendly, energy-efficient system is a
vertical closed loop bore hole system (with 50 bore holes sinking
98m into the ground strata) linked to Mitsubishi Electric’s unique
WR2 ground source heat pump which allows the building to use the
geothermal energy of the earth as a heating or cooling energy store.
Ground source water systems are one of the recognised renewable
energy sources listed as part of the Government’s push for 10%
renewable energy usage, and Mitsubishi Electric’s WR2 and WY City
Multi condensers are the only air conditioning products currently on
the list.
The inverter-driven WR2 units use the geothermal energy from the
earth to either cool or heat their refrigerant circuit, reducing the
energy needed to keep the building at the right temperature. WR2
systems also transfer heat between any of the 24 indoor units
available on each circuit to offer double heat recovery potential
and COPs of up to 7.0.
In addition to the WR2 ground source heat pump system, the roof of
the logistics centre is covered with solar panel water heating which
will provide an average of up to 50% of the domestic hot water all
year.
The low energy, highly insulated building also collects rain water
from the roof for flushing the toilets and elsewhere.
By combining the most environmentally friendly systems suitable for
this locality and looking at all aspects of the building’s services,
Olympus KeyMed has created a building that will consume at least 30%
less energy and 25% less water compared to that of an equivalent
‘traditional’ building, whilst delivering a high quality internal
working environment for staff.
Hot Water & Cool Chefs in Hatfield Kitchens
Mitsubishi Electric recently installed their
newly launched VRF water heating booster unit at their head office
in Hatfield to provide a hot water supply to the building’s kitchen.
The office has an on-site restaurant that can seat 100 people and
serves cooked meals 5 days a week. Employees and guests are offered
breakfast every morning from 8am - 10:30am and lunch every afternoon
from 12pm - 2pm. The kitchen therefore
requires an almost constant hot water supply for a large portion of
the working day.
The 12.5kW water heating unit is connected to a high efficiency VRF
outdoor unit that provides cooling to the kitchen area via 2 ducted
fan coils. The PWFY unit is able to utilise the heat energy
recovered from this area to heat water in a highly efficient
manner, providing the kitchen with a hot water supply.
An M2M IP/50 Maxi unit has been installed as a means of controlling
and monitoring the system, allowing the tracking and logging of data
such as the exact amount of water utilised by the kitchen on a daily
basis, power consumption of the outdoor unit,
power supplied to the PWFY unit and ambient temperatures among other
variables.
The M2M unit also provides a perfect solution for system down time.
If in the unlikely event there is an error at the PWFY unit a signal
would be sent to the M2M which would in turn give an error output
signal. This error signal would then switch on a
back up immersion heater making sure that the kitchen’s hot water
demand is satisfied at all times.
Monitoring of the system over a four month period showed an average
COP of 5.36 reflecting a highly efficient system.
The PWFY air to water heating booster unit is able to satisfy the
hot water demand required from the kitchen on a daily basis in a
highly efficient manner, especially when benefiting from heat
recovery. This in turn has shown an overall reduction in running
costs and CO2 emissions enhancing Mitsubishi Electric’s positive
attitude to combating global warming.
