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 Research and Development team.

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

The Gree GMV6 VRF system employs multi VRF CAN+ communication technology, offering intelligent, efficient control, with ultra-quick response times from 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 from -30ºC~52ºC. There are nine individual outdoor units, which can be connected to give a maximum capacity of 272kW.

Key Features

Wide Operation Range

The GMV6 has a -33°C to 55°C stable operation range to provide users with a comfortable environment in both cold and hot weather. Operating ambient temperature for cooling can be as low as -15°C.

Stable and Reliable Operation

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

Clean and Healthy Fresh Air

The fresh air system satisfies multiple indoor fresh air supply demands.

Quiet and Comfortable Experience

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

Flexible Engineering Design

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

Intelligent Control and Management

Intelligent sensing function control, with 360° panoramic temperature field identification. High-precision temperature field identification achieves cold air prevention and warm air surrounding. Multiple intelligent control ensures a more well-proportioned temperature field. All these features contribute towards higher energy-saving operation.

Smart Era

Gree’s six generation GMV is the accumulation of 33 years of producing world class air conditioners and heat pumps. The GMV6 sits in the Smart Era of Gree innovation: built with all DC Inverter technology, offering high efficiency, large air volumes, multiple prevention technologies, CAN+ communication, and intelligent control for clean and healthy air. Confidently backed by the Gree NZ team, with design, training, commissioning, and after-sales support. For more information, contact Gree NZ today.

High Efficiency EVI Scroll Type DC Inverter High Pressure Cavity Compressor

1. High Efficiency EVI Control Technology

The high efficiency EVI Compressor is developed according to the requirements of the VRF unit. Its 0~420Hz adjustable range can perfectly match with the entire unit to push its performance to the greatest extent.

2. Release Valve

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

3. Improved Asymmetric Wrap

A new asymmetric wrap has been adapted, improving compressor efficiency by reducing internal leakage and invalid superheat.

4. Internal Oil Circulation Structure

Internal circulation of lubricating oil helps to reduce over-heat losses and oil discharge rate, improving efficiency and reliability.

5. Dynamic Oil Balance Structure

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

6. High Speed

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

7. Oil Pump Filter

Carries out 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, improving 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, and wind prevention); CAN+ communication technology; Intelligent control and management. All working to ensure clean and healthy fresh air.

Multiple Prevention Technologies

Protects the unit from corrosion, dust, wind, lightning, and snow, ensuring operational suitability in a wide range of harsh environmental conditions and prolonging the overall service life of the unit. 

Innovative Stratification CAN+ Structure with Multiple Master Networks

Considering that the application of an air conditioning system requires multiple nodes, multi-step control, and intelligent expansion, we have developed the stratification CAN+ structure with multiple master networks, making it possible for the number of nodes in a single system to be increased relatively by 56%, and the response time for centralised control to be shortened immensely.

Large Air Volume with a Low Noise Fan Blade

All GMV6 outdoor units come with a brushless DC Inverter fan motor, with speed adjustment from 5-85Hz in 1Hz increments.

Connected to the new reverse 'S' tail-designed fan blade, along with a new grille design, the GMV6 outdoor airflow has increased by 16%.

The outdoor fan is rated at 110Pa to allow the fitting of a diversion cover. It also has a wind prevention function, as well as 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, multi-step control, and intelligent expansion, traditional network prove to be limited.

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

The multiple master networks make it possible for the number of nodes in a single system to be increased relatively by 56%, and the communication cycle and preferential and centralised control response times to be shortened down to seconds.
