COMFORT

Wide operation range
Low noise, night silent running
Optimal temperature control

Wide operation range, -23°C heating, 53°C cooling

Low noise and night silent running

Optimal Temperature Control

When a multiple number of indoor units are connected, an insufficient or excess amount of refrigerant may be
supplied to indoor units depending on the difference in length of the piping connection from outdoor units
Optimal refrigerant control uses the indoor coil temperature to detect the air conditioning status of each indoor
unit and control the capacity(refrigerant amounts) very precisely

HIGH RELIABILITY

Recycling operation
stage oil return
Oil temperature sensor
High Pressure sensor
Thunder Protection

Recycling operation
Recycling operation ,more long life of compressor

Oil Return

If the compressor operate at low frequency,oil return is only through the capillary.
If the discharge compressor operate at high frequency,oil return is through the capillary and magnetic valve.

Compressor double protection:

Base on the basic air discharge sensor ,MRV IV add the oil temperature sensor at the bottom of compressor

With the oil temperature sensor
Control the on/off of heater of compressor, preventing from the liquid shock of compressor
Control the on/off of heater of compressor, preventing
from the liquid shock of compressor
Judge if the liquid refrigerant enter into the compressor
Compressor oil sub heating protection.

•High pressure sensor for every compressor, back up operation so for the module with 2 compressors ,there are 2 high
pressure sensors and 1 low pressure sensors, total 3 sensors

Thunder protection

There are electricity discharge wire in the terminal block, to lead the
abnormal

voltage into the earth, then to prevent the thunder affect.
