The hospital is operated by InterHealth Care Services (UK) Ltd in partnership with the Cheshire & Merseyside Primary Care Trusts.
The Native BACnet based building management system was installed by Controls Specialists Open Building Systems. Andy Dutton, owner of Open Building Systems, says: "The ABB HVAC drives are very easy to integrate with the BMS. We simply connect them to the communications network, enter their addresses in the system and it is virtually done. It's all very easy."
The ABB HVAC drives are used to run air handling units and fans, for facilities such as operating theatres and MRI scanner rooms. Eighteen of the drives are being used on the project, in sizes ranging from 4 - 15kW.
Offers 'plug-and-play' device integration:
The BACnet communications protocol is native to the drive, with no requirement for additional gateways. The protocol is developed specifically for building services applications and used extensively in continental Europe as well as in the US. BACnet is increasingly being adopted by leading BMS manufacturers. The protocol offers 'plug-and-play' integration of devices in building services.
BACnet is embedded with the standard RS485 interface of the ABB HVAC drive. Other protocols supported by the drive are Modbus, FLN, N2 Metasys, Profibus-DP, Interbus, Lonworks, CANopen, DeviceNet, Modbus Plus, ControlNet and Ethernet.
