Enrico Boscaro, application manager for Computer Room Air Conditioning @CAREL explain the concept of the “integration level” for cooling control in datacenter, mentioning then some of our solutions that might be used for this.

1. The integration level for cooling optimisation:
Carel local and remote supervisory solutions

2. Datacentre cooling: a mix of solutions

3. Integration of solutions: optimisation needed
Example: integration of direct free cooling and CRAC units.
Centralised controller?
 Best solution: unit controller
tested by the manufacturer for
reduced commissioning and
redundancy of controls
 Use of communication to
optimise controllers
(temperature set points, air
flow set points,..)
 Specific HVAC skills are
needed for design and
implementation of control

4. Distributed intelligence: different layers
Unit Synergy
and backup

 Data collection (additional probes, power facilities)
 Data presentation (graphic user inteface)
 Data sharing (i.e. with DCIM) and notification
 Additional HVAC logic for cooling optimization
 Interacting with local/remote controls for Services (maintenance)

6. A new System design of distributed control using
Ethernet capabilities in a «multi layer» approach
Ethernet “Client
Server” topology
allows multiple
clients so DCIM
coexists with
Integration by
means of a cpCO
controller

7. Example of medium datacenter integration with a
PC based system: Plantvisor

8. Plantvisor: Integration and Sevices features
 Data collection using standard protocols
 Parameter setting with different profiles
and variable logging
 Powerfull Interactive Graph
 KPI (Key Performance Indicator)
 Alarm notification
 Scheduler, events and centralized logic
