Case Study

Mills & Reeve, Whitefriars, Norwich

Following a client's brief, a system incorporating cassette style handlers was selected. Each of the 76 air handlers is connected to a refrigeration distribution box allowing for individual climate control of each office zone. The air handlers and distribution boxes are connected to 12 VRF condensing units sited on the roof of the building. The individual offices, open plan offices and meeting rooms have independent remote controllers allowing the occupants to dictate their preferred conditions.

All the air handlers and condensing units are connected to three central controllers - (one per floor). The central controllers ensure that the system is not left running whilst the building is unoccupied.

The central controllers also operate the Lossney fresh heat recovery units, which are more stable and provide fresh air to the occupants of the building with high efficiency.

Works included
  • 76 Cassette Style Air Handlers
  • 12 VRF Condensing Units
  • 25 Lossnay Heat Recovery Air Handlers
