1.3 Main Features

1.3.1 Wide Range and Stepless Capacity Modulation
Wide capacity modulation range 10%-100%)
According to changing the ratio of
the capacity steplessly
Lower the energy consumption and running cost.
1.3.2 Accurate Temperature Control and Quick Response.
The cooling/heating capacity of the indoor units is controlled by the EXV,
which ensure the low temperature fluctuation of
Stepless capacity modulation;
Quick response to output the capacity (40s).

1.3.3 Simple, Reliable and Long Life
The PWM valve has the longevity of 40 million times
Wide range of capacity modulation makes sure
the start/stop times reduces
Less components
No complicate inverter controller
The compressor has an excellent oil return
performance, there is no need for the oil return
circuit
Even the units run in 10% part load, the MDS
system can be in good stage.
