Plant Resilience Chiller

A new single chiller is required to serve a back-up to an existing Daikin chiller. The system serves the building 1degree Celsius cooling coils located within 9 No. Dehumidifiers that maintain a set dewpoint within existing clean & dry rooms.

The current 1degree Celsius chiller circuit is supplied by a single chiller. This circuit supplies the 9 dehumidifier units which serve the cell assembly rooms to achieve the target dew point for this area. The single chiller does not have any back up unit or resilience to prevent the room conditions from being compromised. The requirement of this document is to implement a resilience chiller which will supply chilled water in the event of a failure on the current system and not provide additional capacity to the circuit. The system already has provision to install and additional chiller in parallel to the current asset.
