1.3 Main features

1.3.1 Wide range and stepless capacity modulation
°ˆ Wide capacity modulation range£® 10%-100%) £ª
°ˆ According to changing the ratio of °∞loading time°±and °∞unloading time, MDS can modulate
the capacity steplessly£ª
°ˆ Lower the energy consumption and running cost.
1.3.2 Accurate temperature control and quick response.
°ˆ The cooling/heating capacity of the indoor units is controlled by the EXV,
which ensure the low temperature fluctuation of °¿ 0.3°Ê;
°ˆ Stepless capacity modulation;
°ˆ Quick response to output the capacity (40s).
1.3.3 Simple, reliable and long life
°ˆ The PWM valve has the longevity of 40 million times
°ˆ Wide range of capacity modulation makes sure
the start/stop times reduces
°ˆ Less components
°ˆ No complicate inverter controller
°ˆ The compressor has an excellent oil return
performance, there is no need for the oil return
circuit
°ˆ Even the units run in 10% part load, the MDS
system can be in good stage.
