HP Performance Optimized Data Center (POD) 20cp Manuale Utente
Environmental control system 35
By connecting your HP POD 20c to a BMS system, you can monitor the various parameters and alarms. For
)." The complete list of parameters and
alarms that can be monitored will be discussed with your facilities personnel.
IMPORTANT:
If your site does not have a BMS, HP POD 20c ECS data can be sent to and
viewed from a set IP address. Communication occurs through an Ethernet cable that is connected
Sensors
The HP POD 20c has several temperature sensors that monitor the environmental factors and communicate
data back to the ECS.
Humidity sensors
Two humidity sensors monitor humidity in the cold aisle and report data to the ECS.
Pressure sensors
Six Beckhoff pressure sensors located in the control cabinet measure the differential pressure between the hot
aisle and the cold aisle, as well as the air filters. These pressure sensors monitor the pressure at nine sampling
locations throughout the HP POD 20c and report output data to the ECS. The ECS uses the calculated aisle
locations throughout the HP POD 20c and report output data to the ECS. The ECS uses the calculated aisle
differential pressures to control fan speed and uses the zone filter differential pressure to indicate when filters
need to be replaced.
