The Royal Free Hospital

The Royal Free London NHS Foundation Trust has an ongoing programme of refurbishing and upgrading their large masonry-built air handling plants serving the tower and podium areas of the main hospital.

This project included the refurbishment of 3 Air Handling Plants within the hospital, and to change the requirement from a 12-hour operation to 24 hours, to suit the needs of the departments being served by them.

The works also included the installation of motorised shut-off dampers on the distribution systems of these 2 plants, such that 12 hour operated areas shut down out of hours and the fan speeds reduce accordingly to minimise energy consumption. 1 of the AHU plants is the largest plant on site and serves a significant portion of the podium.
