3.0 UNIT DESCRIPTION
Brushless DC Inverter Technology
This technology is applied to control the speed of the compressor allowing continuous adjustment of the
temperature, in contrast to traditional air conditioning systems where the temperature is controlled by a
compressor that can run only at full speed or complete stop.
The system is equipped with a "Brushless DC" variable speed compressor and relative inverter regulator able
to change and control the motor speed.
The elimination of intermittent (ON / OFF) cycles allows to increase considerably the energy efficiency, the
lifespan of components and increasing the on-board comfort without temperature and relative humidity
fluctuations.
By using unit INVERTER "Brushless DC” it is possible install on board a smaller power generator than the one
necessary for operating a traditional ON/OFF air conditioning.
Energy Saving (40-50% reduction in electrical demand)
As the air temperature approaches the set point value, the inverter control regulates the capacity by
varying smoothly the compressor frequency in order to maintain stable thermal conditions. Thanks to the
variable speed operation and the use of "Brushless DC" motor the efficiency is much higher than ON -OFF
systems, which must continuously stop and start to maintain the temperature.
In terms of seasonal energy efficiency there is a reduction in electricity consumption by 40-50% compared to
traditional air conditioning systems.
The following diagrams give an idea of the operation logic (PID) of this variable speed system.
