3、 Units characteristic
☆ Wide operating range with outdoor air temperatures up to -15℃ in cooling for the Heat pump
☆ High efficiency and energy saving
☆ Auto-restart after a power supply blackout
☆ Single-phase power supply thanks to DC inverter technology low consumption
☆ Dynamic refrigerant control by DC inverter compressor and circuit, electronic valve and fuzzy logic
managed by a powerful micro program
☆ EEV for each indoor unit
We leaded to adapt 180°sine wave with permanently magnetic and synchronized
Brushless motor, compressor motivated from 120°square wave control to 180°
sine wave. These contribute higher efficiency, lower power consumption and noise.
Compressor motivated
by 180°sine wave
High precision of flow control valve, Compared with the on/off unit, DC inverter
with large range of flow, accurate has the advantage of fast refrigeration of
control, these could implement calefaction, accurate temperature control,
automatically control to refrigerant reliable system, high efficiency and so on.
and help system always run at the
best condition..

In fact , the new CS is a high efficiency DC inverter technology outdoor unit，its
SEER is as high as 21 for the 12K unit。 when compared to SEER13 ， it can
save electricity 38℅ in a year.
