ADVANCED HIGH EFFICIENCY TECHNOLOGY
„ „
Large propeller fan
High performance and low noise
realized by large propeller and
optimization of angle.
DC fan motor
Miniaturized, low noise, high
efficiency, multi-stage DC fan motor
is mounted.
Large heat exchanger
Heat exchange performance is
substantially improved by mounting
of 3-row large heat exchanger.
High efficiency compressor motor
Optimized refrigerant flow design
Highly accurate parts
- (01 - 02) -
DC inverter control
Efficiency is improved by
mounting of new active filter
module.
Subcool heat exchanger
Cooling performance is
improved by mounting of dual
tube heat exchanger.
