Dual Cooling (CHW+DX)

Apart of remote air cooled compressorized features, a recovery coil shall be integrated into the unit.

When the recovery coil is active the standard cooling devices are only ON if the room temperature exceeds a certain value; adding the effect of the recovery coil plus the cooling devices lowers the temperature, yet before reaching the set point the cooling devices are switched off again. The cooling devices in this case help the recovery function, but do not replace it. In the following diagram, it can be seen how the steps of the cooling devices are shifted to ensure energy savings.
