1.3.3 Precise oil control technology
5 stages oil control technology ensures all outdoor unit and compressor oil is always kept at a safe level,
completely solving any compressor oil shortage problems.
1st stage:
Compressor internal oil separation.
2nd stage:
High efficiency centrifugal oil separator (separation efficiency up to 99%) ensures oi
l
separated from the discharge gas is returned to the compressors.
3rd stage:
Oil balance pipes between compressors ensure even oil distribution to keep compressors
running normally.
4th stage:
Oil balance pipes among modules ensure even oil distribution among modules.
5th stage:
Auto oil return program by monitoring the running time and system status ensures reliable oil
return.
1.4 Enhanced comfort
1.4.1 Night silent operation mode
Night Silent Mode feature which is easily set on the PCB board allows the unit to be set to various time options
during Non-peak and Peak operation time minimizing the units noise output.
1.4.2 Intelligent defrosting technology
Intelligent defrosting program will judge the defrosting time according to the system real requirement, reduce
heating loss caused by unnecessary defrosting and create more comfort.
Defrosting time can be shortened to 4 min. due to the specialized defrosting valve.
