OPERATION AND MAINTENANCE MANUALWall Mounted 0121…0661Monobloc Wall Mounted Unit - WMA/WMF 0121-0181-0251-0281-0331-0551-0661 - Rev. 2.0. - Date: 18-07-2000 EN 9 (32)INTELLIGENT FREE-COOLINGThis 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 thecommon fixed-point free-cooling systems.The microprocessor compares the thermal load present at that moment in the air conditioned environment with theoutside temperature, calculating the optimum temperature at which to start free-cooling. In this way the temperatureat which free-cooling starts is not fixed but changes to adapt to the load conditions present at that moment in the airconditioned environmentIf required, fixed point or fixed differential free-cooling cycles can also be activated; this type of function does notconsider the heat load in the room. |
