During the design stage of the project our client Trinity College Dublin expressed an interest in reducing the running cost of the building. This was best achieved by means of heat recovery. The design and functionality of the building meant that the heating and cooling need could only be met by means of air handling units.
The standard air handling unit were designed into a highly efficient unit using thermal wheels, ultimately saving energy and reducing carbon emissions. Once a high cost application, thermal wheels are now a leading component for heat recovery because they can handle large air volumes where usually efficiency would be low.
85% of heat can be recovered by thermal wheels by transferring it to incoming fresh air, this also has a positive impact on carbon footprint.
There were other environmental advantages of the thermal wheel. Firstly, its small carbon footprint allowed the size of the AHUs to be reduced. This means that capital expenditure will also reduce. It also reduced the size of heating or cooling coil and allowed a reduced capacity boiler and cooling condenser.
