Dunstar Ltd - based in the West Cork town of Clonakilty -
have had their pioneering efforts in renewable energy technologies
recognised by three awards at the Plan Expo Product of the
Year Awards 2006, which took place towards the end of last
year at the RDS in Dublin.
The awards included -
- Best Innovation Award Winner
- Best Renewable Product - and
- Overall Winner.
The awards relate to a patented combined heating and cooling
geothermal system developed by the company and installed in
a number of prestigious buildings around the country. Combining
the heating and cooling outputs of a Ground Source Heat Pump
offers a cost effective and environmentally sensitive solution
to buildings with heating and cooling loads - load requirements
which sometimes exist simultaneously.
In place of conventional air cooled chillers and a boiler
plant, a geothermal resource can act as a thermal source or
sink. While the initial capital cost is higher, running costs
are lower - with reductions of up to 75% possible when compared
to conventional systems.
When simultaneous loads exist, one of these loads is being
satisfied free of charge. If additional heat input or heat
dumping is required, the geothermal reservoir is brought into
play. Operating co-efficients of performance of up to 8.0
The system is particularly effective when a dehumidification
requirement exists. The energy released when removing moisture
from the air is re-used within the same system in order to
re-heat the air stream.
The application of this technology offers building designers
- and their customers - not only running costs and environmental
impact savings - it also allows for cooling loads to be dealt
with without the need for visible external plant or noisy
