Low noise level
Night quiet operation function
Noise can be reduced to 45dB (A)
Low noise operation
■DC INVERTER compressor, smooth operation, no need frequent start the compressor, effectively reduce the
noise outdoor
■Vector inverter control, more precise control
■DC fan motor, motor bracket used the non-resonance structure, ensure smooth running of the motor, reduce
operating noise
■Big diameter fan, design according to aviation quieter principle
DC motor
High reliability
Refrigerant automatically reclaim technology
Set refrigerant automatically reclaim through dip switch,
the refrigerant in indoor and pipe can be automatically
return to outdoor, convenient in maintenance and
reducing waste of refrigerant, reduce customer
maintenance cost, improve the efciency of after-sales
maintenance
Refrigerant control technology
Refrigerant control technology without high pressure
accumulator, reducing the refrigerant volume and
enhancing the running efciency
