For this data centre with a ‘hot aisle’ and ‘cold aisle’ design, the idea was to provide a packaged and self-contained solution with the machines integrated indoors on the data centre’s upper slab.

The 2 machines were designed as ‘4-damper’ type units. What’s special about them is that they operate like air-to-air heat pumps, but with additional thermodynamic energy recovery.
The refrigeration circuits are regulated according to the return air temperature from the hot aisles.
In addition, to limit the amount of ‘water weight’ added by the fresh air, the PLC compares the outside water weight with the setpoint to adjust the right amount of fresh air.
