Aisle Cooling Module

PRINCIPLE:

The warmed air coming from the servers is blown into the contained hot aisle.
The ACM modules measure the differential pressure between the aisle and the room.

ADVANTAGES

Optimised regulation:

• Regulation of the air flow by measuring the aisle/room differential pressure, and submission of the flow of the exchanger to the actual flow rate of the servers: no disturbance to the proper regulation of equipment
• This principle also provides automatic redundancy between the different modules of the same aisle: in the case of stopping an ACM, the flow rate of the others increases automatically
• Regulation of the flow of water by 2 or 3 channel proportional valve
• Output temperature chosen by setpoint assigned via web page
• No jerks on the pumps of the water circuit: overall constant flow.
• Losses of water loads lower than 1 bar under 7m3/hr
• Management by programmable logic controller with possible extensions in:
  • ModBus RTU
  • Modbus TCP/IP
  • SNMP
  • Dry contact
