Project Nelson

Mercury Air Conditioning carried out the installation of new air conditioning into an iconic London building which has helped the headquarters of a local government finally become cool again.


Each of the 5 floors had existing VRF systems installed, which were not functioning correctly due to their age and a variety of faults. These systems were condemned and replaced under a life cycle plan, utilising Daikin's energy efficient Heat Recovery VRV IV with multi branch selector boxes and a variety of indoor units. Indoor units ranged from Wall Mounted (FXAQ-A), Floor Standing (FXLQ-A) and concealed floor standing (FNXQ-A) which were ducted to new linear supply & return grilles to avoid the short cycling that the previous installation had faced.


Our team had to stick to strict deadlines, working around other building contractors, government recess and occupiers in the building so timing was a key factor to ensure we could fit all necessary pipework and indoor units into the correct locations, as approved under Heritage and listed building consent. 


This was an intricate project, with the pipework routes and design changing frequently to suit the requirements of the building and our findings of existing routes once access had been granted to those areas! Our internal design team were no match for these challenges though!


We are pleased and proud to say this project has been commissioned & handover over to the occupier both on time and on budget.
