1.2 Product Functions and Features
Gree GMV6 DC inverter multi VRF system adopts the advanced technologies such as efficient low-
temperature enthalpy-adding system, partition heat exchange flow path, subcooling design, integrated
aluminium electronic control, reliable operation control under ultra low temperature and so on, so
the unit can operate smoothly between -30
℃ ～
55
℃
. It provides comfortable environment for the
user no matter in severe cold or intense heat. The capacity range of GMV6 is 22.4kW
～
272kW, from
8HP
～
96HP, 45 models in total. Wide capacity range and flexible combination. It can be applied to the
commercial occasions like large office building, production factory, large malls or residential villa.
Compared with GMV5, GMV6 series can not only realize low temperature heating function, operation
range under low and high temperature is wider, but also has all the functions of GMV5.
Energy-efficient
Thanks to the advanced full DC inverter technology, optimized AC system design and precise intelligent
control technology.
Efficient DC inverter low temperature enthalpy-adding scroll compressor
The compressor adopts the high pressure chamber of excellent performance. It inhales directly and
reduce the overheat loss to improve compression efficiency.
Adopting the high-efficiency permanent synchronous motor, its rotor is permanent magnet, the stator is
intertwined centrally and the efficiency is higher than the normal DC inverter compressor.
Sensorless DC inverter fan motor
The DC inverter motor adopts the electromotive force to realize electrodeless speed regulation between
5Hz-90Hz. Compared with normal DC inverter motor, its operation current is smaller, input motor
power is lower and efficiency is greatly enhanced.
Leading torque control technology
It processes minimum current and maximum torue control technology
Utilize DC inverter compressor rotor magnetic resistance torque effectively, allowing the minimum
current to output the maximum torque, reducing motor winding loss and realizing higher efficiency.
Directly control the motor torque to realize ultra low speed operation of DC inverter fan motor, torque
pulsation is small, satisfying system demand while achieving comfort of higher requirement.
Quiet
Gree DC inverter multi VRF system fully considers comfort requirement, the humanized technology
upgrade the comfort perfectly. The wider operation range of the unit ensures normal operation under
severe cold or intense heat; quiet effect is better, creating a quiet working and living environment.
Quiet mode of ODU
Quiet at night
The system will memorize and judge the highest outdoor temperature. When the system is operating at
night in low load, it will enter quiet mode automatically. Based on actual application occasion, 9 kinds
of quiet mode can be set.
For example, it will enter night operation mode automatically after operating for 8h, then it enters
normal mode after 9h.
Compulsory quiet
When the unit is installed in the locations with lower noise requirement, quiet operation is necessary
no matter in the daytime or evening, at this time, you can have three kinds of compulsory quiet mode
setting to ensure that the unit is operated under low noise mode at any time. The lowest noise value is
as low as 40dB

.
Quiet mode of IDU
IDU also adopts DC inverter motor to realize the electrodeless adjustment of speed regulation, reduce
noise value greatly, sets auto quiet mode for IDU through wired controller. Start auto quiet function
according to indoor temperature and people activity, the noise is as low as 22dB
