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.
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.
