Client description

IBM Hursley C Block AHU Replacement

Contract details

The project consisted of the replacement of the supply air handling unit fans within the C block roof plant area, which serve the C block restaurant and catering offices. There are 2 AHUs in the plantroom located on the roof of C Block.

The 2 existing belt driven centrifugal suppling fans, & control panels, were stripped out and replaced with multiple direct drive fans mounted on a new frame wall within the existing fan chambers.

The existing Main Control Panels (MCPs) (MCCs) in each plantroom were modified. The existing isolators, power cables & protective devices were retained to serve the 2 new Distribution Boards (DB) which provide power and local isolation to each new fan wall.

The UNIcon controllers communicate with each individual fan in the fan wall via a MODBUS link, and provide the necessary run & alarm functions between the BMS and each fan.

The existing Fan Control Panel (FCP) has been modified with Tridium BMS Controls and Ziehl Unicon Master Controllers to monitor and control all 2 fan walls, and contains all the fan & BMS controls. The UNIcon controllers communicate with each individual fan in the fan wall via a MODBUS link, and provide the necessary run & alarm functions between the BMS and each fan.
