Free Cooling
MiniSpace EC with Direct Free Cooling
The MiniSpace EC unit with Free Cooling option features a preinstalled outside air damper and circulating air damper, and can be fitted directly to the wall.
MiniSpace Eco-Cool combines Free Cooling and compressor cooling in 4 stages:
Free Cooling
Outside air damper opens. Outside air flows through the filter directly into the unit, then into the IT room; compressor off.
Extended Free Cooling
The cooling capacity is kept constant by increasing the airflow. Outside air damper open; compressor off.
Mixed mode
If the fan reaches maximum speed and Extended Free Cooling is no longer sufficient, the compressor is switched on for support; outside air damper open; compressor runs in partial load mode.
DX mode
The unit works in Compressor mode; outside air damper closed.
