GMV- High Capacity Outdoor VRF Inverter Unit
The Gree GMV (Variable Refrigerant Flow) is a high-capacity, modular technological platform engineered for large-scale commercial and industrial infrastructure. Utilizing advanced EVI scroll compressor technology and DC inverter motors, the system ensures high-efficiency performance even in extreme ambient temperatures ranging from -15°C to 55°C.
Key features for building owners and MCSTs include:
- Modular Scalability: Basic units (8HP, 10HP, 12HP) can be combined to reach a massive maximum capacity of 48HP.
- Advanced Networking: Proprietary CAN+ communication technology provides high resistance to interference and allows for the massive expansion of connectable indoor nodes.
- Intelligent Management: Includes a sophisticated billing system for fair energy distribution among tenants, as well as remote monitoring through the G-IEMS and cloud-based platforms.
This system is best used for skyscrapers, shopping malls, office buildings, and hotels where reliable, large-capacity cooling and complex facility management are required.
Supported Indoor Units
High Capacity and Modular Scalability
- Massive Combinations: The system is built on modularity, allowing basic units (8HP, 10HP, and 12HP) to be combined to reach a maximum capacity of 48HP.
- Extensive Unit Networking: It can support a massive number of indoor units connected through a single system, making it ideal for skyscrapers and large malls.
Extreme Efficiency and Performance
- EVI Compressor Technology: It utilizes high-efficiency Enhanced Vapor Injection (EVI) scroll compressors, which reinforce system capacity and allow for stable operation in extreme ambient temperatures ranging from -15°C to 55°C.
- Advanced Energy Management: Building owners can utilize multiple energy-saving modes, such as the “Compulsory Energy-saving Mode,” which can limit output to 80% or 90% to help facilities meet city peak power requirements and reduce costs.
Industry-Leading Communication
- CAN+ Technology: The system employs the proprietary CAN+ communication protocol, which uses a non-polarity chip for high resistance to electromagnetic interference.
- Fast Response: This technology offers significantly faster response times (milliseconds) compared to traditional protocols and simplifies commissioning with automatic address allocation
Robust Reliability and Backup Functions
- Diversified Backup Operations: A major pro is the system’s “emergency functions.” If one module, fan, compressor, or sensor in a modular system fails, the remaining components can continue to operate, preventing a total system shutdown.
- Prevention Technologies: The units are equipped with specialized functions to handle environmental challenges, including dust prevention (auto-cleaning), wind prevention, and lightning protection.
Superior Engineering Flexibility
- Super Long Piping: The system supports exceptional installation distances, with a maximum actual single pipe length of 200m, a total piping length of 1,000m, and a height difference between indoor and outdoor units of up to 110m.
- High Static Pressure Design: Outdoor units feature a high static pressure design (up to 110Pa), which facilitates better air diversion and allows for more flexible mechanical floor designs
Specialised Management Tools
Remote Monitoring: Through platforms like the Intelligent Remote Eudemon and G-cloud, managers can monitor energy consumption and perform maintenance diagnostics remotely via the cloud
Most Suitable Uses:
- Skyscrapers and Office Buildings: These require the massive capacity provided by modular combinations (up to 48HP) and the ability to network many indoor units across multiple floors.
- Shopping Malls and Hotels: These benefit from the system’s stable performance in extreme ambient temperatures (ranging from -15°C to 55°C) and its diverse indoor unit options, such as high-static pressure ducts and cassettes.
- Multi-tenant Facilities: The system’s intelligent billing framework makes it perfect for facilities managed by MCSTs or building owners who need to calculate and distribute electricity costs fairly among different tenants.
