Gree AI Multi VRF Unit GMV6, a Big Hit at Canton Fair
GUANGZHOU, China, Apr. 16, 2018 /Xinhua-AsiaNet/--

On April 16, Gree Electric Appliances Inc. of Zhuhai exhibited the AI Multi VRF 
(Variable Refrigerant Flow) Unit GMV6 at the China Import and Export Fair 
("Canton Fair"), which had its world debut at Beijing Refrigeration Exhibition 
last week.

During the promotion at the Canton Fair, Mr. Ouyang Jun, Vice General Manager 
of Gree Overseas Sales Company introduced that, through in-depth combination 
with AI technology, GMV6 has several functions such as low energy consumption 
under standby status, positioning self-adaptation, self-diagnosis, and more.

Low standby energy consumption, energy-saving and eco-friendly 

Generally speaking, apart from operation, the air conditioner is under standby 
status in most of the time. To maintain the reliability of compressor startup, 
however, traditional multi VRF units need to keep heating capacity with 
electric heating belt to avoid liquid refrigerant from entering, which might 
affect the lubricant. Therefore, the units will generate additional standby 
energy consumption, which is 40W on average. 

With Gree's innovative G-WFC technology based on weather forecast and 
feedforward control strategy of compressor refrigerant transfer, GMV6 is able 
to predict the variation trend of future weather and temperature in advance, 
further control the compressor oil temperature heating belt intelligently, 
which can reduce 80% of startup time for electric heating. Power consumption 
under standby status for outdoor unit is as low as 1W.

Self-adaptation to different locations, a "smarter" air conditioner 

In different regions and locations, consumers' user experience for the same 
unit is not always the same. The built-in fixed programs of traditional units 
fail to satisfy diversified demands in regions with high emergency needs under 
complicated environment. This time, GMV6 successfully tackles the core 

With the support of self-adaptive technologies to different locations, GMV6 can 
judge the altitude of the unit through GPS and predict parameters by combining 
the atmospheric pressure and automatically control the air flow, ensuring the 
best user experience and also the efficient operation. 

As for the air conditioning problem of slow defrosting in high latitude regions 
under heating mode, GMV6 can obtain the optimal operation frequency for 
compression under the conditions of different temperature and humidity, 
formulate diverse defrosting modes with climate features, thus realizing 
parameter self-adjusting and intelligent custom defrosting mode, bringing more 
comfortable experience to the consumers.

Self-diagnosis as a preventive measure

It's difficult for traditional air conditioners to predict any hidden troubles 
and eliminate the errors in advance. With self-prediction and self-diagnosis 
technology, Gree AI Multi VRF Unit is able to conduct timely detection for the 
application condition of the unit, carry out analysis on compressor core 
parameters, keep learning the existing operation parameters and error 
maintenance data, establish the corresponding relationship between unit 
operation features and errors, and then proceed diagnosis and prediction for 
the error.

Expressing his favor towards this smart Unit which helps save a lot of power, 
Deputy CEO Eng.Hamed from Basic Electronics Co., Ltd., Gree's exclusive agent 
in the Middle East, said at the promotion event, "the diversification and 
intelligence of energy information is what we are longing for. I'm so glad to 
see that Gree is sharing the highly-anticipated AI revolution with the world." 

Under the background of globalization, every field is developing with 
coordinated efforts, and the rapid development of manufacturing industry is 
going to provide a wonderful life for the people all over the world. The 
promotion of Gree AI Multi VRF Unit at Canton Fair further shares the 
technological achievement of AI in air conditioning field to the whole world.
