Mitsubishi Electric
- the Future is Renewable & Sustainable
Legislation is now driving businesses to
demonstrate that their buildings are energy efficient and minimise
CO2 emissions.
With EU law accepting air source heat pumps as a
renewable energy source, Mitsubishi Electric can offer an extensive
range of highly efficient renewable products that allow clients to
not just meet but exceed the targets set by legislation.
Heat Pumps
Heat pumps upgrade naturally occurring low
temperature heat into useful high temperature heat and vice versa
(see diagram on right). The operational characteristics of a heat
pump are totally different to a traditional boiler. With a
conventional boiler, 1 kilowatt of energy in gives less than 1
kilowatt of heat to the building. With a typical electrically driven
heat pump boiler, 1 kilowatt of energy in will give 3 or 4 kilowatts
or more of heat to the building, and these efficiency levels are
predicted to rise year on year.
Mitsubishi Electric uses heat pumps in its
advanced air conditioning units to maximise the heating and cooling
potential of each system and minimise the energy consumption and CO2
emissions.
Heat pumps offer a real potential for energy and
CO2 reduction within buildings and especially within the home. This
innovative new technology offers the possibility of low carbon
residential heating or heat recovery commercial heating, cooling or
ventilation.
Ecodan
Ecodan heating systems are setting the standard
for mass-market, low carbon residential heating. With easy
installation, Ecodan offers an average reduction of 50% in CO2
emissions and a 30% reduction in running costs against a modern
gas-fired boiler. Savings are even greater against old gas, oil or
LPG.
Air Curtain
The PHV DX range of air curtains offers a 67%
reduction in both CO2 emissions and running costs over conventional
direct electric models, and has been developed to offer a highly
efficient way of providing a comfortable climate for customers and
staff without compromising on performance.
The six models in the range link to a Mr Slim
R410a outdoor heat pump compressor unit, which uses advanced
inverter technology to cut energy wastage and offer more flexibility
of design and placement.
WR2 / WY Series Ground Source Heat Pumps
Mitsubishi Electric’s water cooled City Multi
range is listed on the Government’s renewable energy list and tests
at the company’s Hatfield headquarters have proven that this
technology is 300% more efficient at heating and cooling an office
than a traditional gas-fired boiler and rooftop chiller combination.
Available in heat pump and heat recovery with
model sizes of 8, 10, 16 and 20HP, both the WR2 and the WY can be
linked to ground loops and boreholes to use the geothermal energy of
the earth like a battery to store heating and cooling energy. All
models are inverter driven with low starting currents and the same
piping lengths as the air cooled versions.
PWFY
These VRF water heating units provide an energy
efficient solution to commercial heating, cooling and hot water
supply, by using excess energy to supply a building’s hot water
supply and remove the need for a traditional boiler.
The 12.5kW booster unit can achieve a flow
temperature of 70ºC using the first ever VRF cascade refrigeration
system between R410A and R134a refrigerant. The efficiency of the
unit is maximised when using heat recovery technology, which
utilises otherwise wasted heat energy rejected from areas of a
building that require cooling, to heat water.
Using heat pump technology both the 12.5kW and
25kW air to water heating units are able to achieve flow
temperatures of 45ºC in heating and 10ºC in cooling, making them
perfect for application on underfloor heating/cooling systems. The
energy efficiency of these units is maximised when using the
built-in flow temperature controller which automatically varies the
flow temperature depending on the ambient temperature. This enables
the output temperature to be reduced on milder days allowing the
system to run at partial load.
Zubadan
The new City Multi and Mr Slim Zubadan systems
use a unique flash injection circuit to allow the condensers to
continue delivering full heating capacity at outdoor temperature as
low as -15ºC, and increases the guaranteed operating range down to
-25ºC.
This system optimises refrigerant flow in low
ambient conditions by allowing some of the refrigerant to bypass to
the compressor through a flash injection circuit to maximise the
heating efficiency and increase the heating range. The flash
injection circuit allows the system to run for much longer periods
between defrosts, runs at a much higher capacity during this cold
ambient and reduces the period that the unit is in defrost.
Lossnay
Lossnay's simultaneous air exhaust to air supply
heat transfer element provides effective ventilation, total heat
recovery (sensible and latent), providing a comfortable air
temperature within the room. The energy saved by using Lossnay
contributes towards lowering the running costs of air conditioning,
minimising the size of air conditioning systems needed.
Multi-ventilation mode allows the supply air to balance the exhaust
air, varying dynamically to meet the usage environment and location
requirements. A free-cooling function with more running cost
reduction is also available.
The Mitsubishi product range also includes VRF
Air Conditioning, Passive Ventilation and Close Control AC.
