Split-system heat-pump installation addresses noise issues
An unusual split-system water-source heat-pump system from McQuay to provide heating and cooling for the Irish Times in Dublin overcomes noise problems often associated with this type of system.
Unusually quiet air conditioning using split-system water-source heat pumps is achieved in the new building of the Irish Times in Dublin using McQuay UK’s WSHP system. The compressor/ condensing section is split from the fan-coil unit, eliminating noise problems from the compressor. The contract is worth over £200 000 and involves Marren Engineering of Dublin installing 120 WSHP units in the 8-storey building near the Liffey River and designed by Will Revert. The eight floors, including a roof-top restaurant and boardroom, have an average of 16 units per floor. They are mainly concealed in ceilings and have heating capacities from 3 to 11.9 kW. A common water loop installed by the developer connects all the compressor sections together to enable each WSHP to share recovered heating or cooling. A boiler and dry cooler provide additional heating and cooling when required. The system is monitored and managed through a McQuay Smart central controller, which enables the publisher to view the status, set operating modes and parameter valued for each unit or group of units.
