Part2 Features
1. Outdoor Units
Environmental-friendly Refrigerant R32
The GWP value of R32 is smaller, so the effect on the greenhouse effect is smaller. The ODP
value of R32 is 0, so it’s no harm to our planet’s ozone layer.
High Efficiency
Equipped with high efficiency DC Inverter compressor, adjustable fan motor and advanced
180° sine wave vector driver, the system can be higher than 6.1 in SEER and 4.0 in SCOP so as
to meet the European and Australian new energy efficiency standards.
Reliability
Stable cooling under -10°C and heating under -15°C outdoor environment temperature.
180
°
Sine Wave Control
DC inverter compressor uses 180°sine wave vector control technique, make compressor
motor operates smoothly and efficiency increases significantly.
