Redundancy ensured by three different functionalities.

Computer and server rooms are very sensitive areas of application. Any downtime caused by high room temperatures must be avoided by any means. Air conditioner redundancy is one of the key points to ensure a reliable nonstop cooling operation.

  


a. Power supply error or PCB error / b. Operation / c. Error / d. Stand by / e. Operation 

Backup operation.
When an air conditioner fails for whatever reason, another one will awake from standby mode and cover the room’s cooling load.


a. Temperature threshold exceeded (cooling) / b. Temperature falls below threshold (cooling) / c. Operation / d. Stand by 

Support operation.
Support operation, also called cascade control, makes sure that the capacity required to cool the room is delivered by one or more units whenever required. When the capacity of 1 air conditioner is not sufficient, another one will be started to support the operation.



a. Operation / b. Stand by 

Rotation operation.
Backup and support operation are key functions for a redundant operation in computer rooms. This concept implies a main system and a sub system. In order to avoid an imbalance of the operating hours of the systems, the redundancy control equalises the operation time by rotating the main and the sub systems, thus providing a “rotation operation”.
