INTELLIGENT FREE-COOLING
This system gives dynamic control of the free-cooling phase, maximising energy-saving performance at all times.
The result is the ability to provide much greater energy saving (and therefore economy of operation) than the
common fixed-point free-cooling systems.
The microprocessor compares the thermal load present at that moment in the air conditioned environment with the
outside temperature, calculating the optimum temperature at which to start free-cooling. In this way the temperature
at which free-cooling starts is not fixed but changes to adapt to the load conditions present at that moment in the air
conditioned environment
If required, fixed point or fixed differential free-cooling cycles can also be activated; this type of function does not
consider the heat load in the room.
