1 General Features
1.1 Wide Range and Stepless Capacity Modulation
• Wide capacity modulation range (10%-100%)
• According to changing the ralio of “loading time” and “unloading time”. MDS can modulate the capacity
steplessly.
• Lower the energy consumption and running cosl.
1.2 Accurate Temperature Control and Quick Response
• The cooling/heating capacity of the indoor units is controlled by the EXV. which ensures the low theperature
fluctuation of 0.3
O
C.
• Stepless capacity modulation.
• Ouick response to output the capcity (40s).

1.3 Simple, Reliable and Long Life
• The PWM valve has the longevity of 40 million times.
• Wide rage of capacity modulation makes sure the start/stop times reduces.
• Less components.
• No complicate inverter controller.
• The compress or 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.
