GREE VRF GMV5 Series Review

The GREE GMV5 VRF Series is one of the most advanced commercial HVAC solutions in the global market, offering high performance, intelligent control, and remarkable energy efficiency.

Developed by GREE Electric, the world’s largest air conditioning manufacturer, GMV5 systems deliver precise temperature control and reliability for offices, hotels, hospitals, and large retail spaces across the UK.

System Overview

The GMV5 system uses a variable refrigerant flow (VRF) network capable of connecting up to 80 indoor units per system.
The modular outdoor configuration (from 8 HP to 88 HP) allows scalable installations that adapt to projects of any size — from small business centres to entire building complexes.

Performance and Efficiency

• SEER: up to 8.5

• SCOP: up to 5.4

• Energy Class: A+++

• Cooling Range: –5 °C to +52 °C

• Heating Range: –25 °C to +30 °C

The DC Inverter Twin Rotary Compressor with a vapour injection cycle enhances low-temperature heating performance and extends operating limits for harsh UK winters.
Efficiency increases by up to 15 % compared to the GMV4 generation.

Refrigerant and Environmental Impact

Operating with R32 refrigerant, the GMV5 reduces GWP by 68 % and meets EU F-Gas Phase-Down targets.
It also includes intelligent refrigerant control that dynamically adjusts flow based on real-time demand to prevent overcharging or oil return issues.

Smart Control and Connectivity

The GMV5 integrates seamlessly with GREE Intelligent Control System, supporting BACnet, Modbus, and KNX communication.
Users can manage thousands of indoor units through a single interface, monitor energy consumption, and perform remote diagnostics via the GREE Cloud Platform.

Heat Recovery and Zoning

Available in Heat Pump and Heat Recovery configurations, the GMV5 allows simultaneous heating and cooling in different zones.
This feature saves up to 40 % of annual energy consumption, particularly beneficial for buildings with variable occupancy patterns.

Installation and Maintenance

Total piping length up to 1 000 m and vertical separation of 110 m provide excellent design flexibility.
Self-cleaning condensers, oil management systems, and built-in fault monitoring simplify long-term maintenance.

Noise and Comfort

Outdoor units operate as quietly as 50 dB(A), while indoor units range from 23–32 dB(A).
Variable fan algorithms ensure stable comfort with minimal noise fluctuation.

Conclusion

The GREE GMV5 VRF Series combines modular flexibility, energy intelligence, and superior comfort performance.
For UK projects requiring scalable, eco-friendly, and cost-efficient HVAC solutions, GMV5 stands as a strong alternative to established Japanese VRF systems.
