Gree GMV 6

Modular Inverter VRF System

Gree’s all new generation GMV6 modular inverter VRF system is the result of constant improvement by the Gree R + D team.

The heart of the unit is an Economised Vapor Injected Scroll compressor coupled with the new G-Type heat exchanger with double zones and a high efficiency refrigerant flow path. This reduces the unit’s overall footprint, whilst increasing the heat exchange area and improving the heat exchange efficiency and thus, overall efficiency.

The Gree GMV6 VRF system employs multi VRF CAN+ communication technology offering intelligent and efficient control with ultra quick response times with up to 80 indoor units.

The new Gree GMV6 VRF system is excellent in all aspects of energy conservation, comfort, and stability. Gree GMV6 can work under a wide temperature range, -30ºC~52ºC.  There are nine individual outdoor units, and they can be connected to give a maximum capacity of 272kW.

Key Features

Wide Operation Range

-33°C - 55°C stable operation to provide users with comfortable environment in both cold and hot weather, operating ambient temperature for cooling can be as low as -15°C.

Stable and Reliable Operation

GMV6 adopts CAN+ communication, multiple oil circuits control and other technologies which greatly improve the stability and reliability of the uni.

Clean and Healthy Fresh Air

Fresh air system satisfies multiple indoor fresh air supply demands.

Quiet and Comfortable Experience

GMV6 adopts multiple professional noise-reduction technologies to improve the operation of the unit and create a quiet and comfortable environment.

Flexible Engineering Design

Ultra-long connection pipe, convenient maintenance and other designs are adopted. The engineering adaptability of the unit is strong, which satisfies various engineering demands.

High Efficiency EVI Scroll Type DC Inverter High Pressure Cavity Compressor

1. High Efficiency EVI Control Technology

High efficiency EVI compressor, which is developed according to the requirements of the VRF unit, its 0~420Hz adjustable range can perfectly match with the entire unit, to excel the performance to the greatest extent.

2. Release Valve

Improving partial load energy, adapting to the condition of the variable pressure ratio, upgrading compressor performance.

3. Improved Asymmetric Wrap

A new asymmetric wrap is adopted, and compressor efficiency is improved by reducing internal leakage and invalid superheat.

4. Internal Oil Circulation Structure

Internal circulation of lubricating oil to reduce over-heat losses and oil discharge rate and to improve efficiency and reliability

5. Dynamic Oil Balance Structure

Advanced oil balance technology, with high reliability and flexible design without installation limit. This can realise parallel connection of compressors with different delivery capacities and revolving speeds.

6. High Speed

0~420Hz stepless inverter operation, wide adjustment range of capacity with precision of 1Hz.

7. Oil Pump Filter

Filtration of any impurities to ensure that the oil supplied is clean.

8. Positive Displacement Gear Pump

Ensures the necessary oil supply regardless of the compressors revolving speed, improves the reliability of the compressor.

Inverter Build with All DC Inverter Technology

High energy efficiency, Large air volume low noise fan blade, Multiple prevention technologies (corrosion prevention, lightning prevention, dust prevention, wind prevention), CAN+ Communication Technology, Intelligent control and management, Clean and healthy fresh air.

Multiple Prevention Technologies

Protecting the unit from corrosion, duct, wind, lightening and snow, to prolong the service life of the unit and to suit different environmental conditions.

Innovative Stratification CAN+ Structure with Multiple Master Networks

Considering that the application of an air conditioning system requires multiple nodes, multistep control and intelligent expansion, we originally developed the stratification CAN+ structure with multiple master networks, which makes it possible for the number of nodes in a single system to be increased relatively by 56% and the response time for centralized control to be shortened by hundreds of times.

Large Air Volume, Low Noise Fan Blade

GMV6 outdoor units come with a  brushless DC inverter fan motor with speed adjustment from 5 to 85Hz in 1Hz increments.

Connected to the new Reverse “S” tail designed fan blade and along with a new grille design; the GMV6 outdoor air flow has increase by 16%.

The outdoor fan is also rated at 110Pa to allow the fitting of a diversion cover and has a wind prevention function and the ability to run backwards to blow dust and dirt from the outdoor heat exchanger.

Innovative Stratification CAN+ Structure with Multiple Master Networks

When we consider the application of an air conditioning system, which requires multiple nodes, multistep control and intelligent expansion, traditional network structures are limited.

Gree have developed the stratification CAN+ structure with multiple master networks to improve this. 

This makes it possible for the number of nodes in a single system to be increased relatively, by 56% and the communication cycle, the preferential and centralised control response times to be shortened to seconds.
