High efficiency and sustainable comfort with GRV air conditioning systems
Experience the benefits of dual full inverter compressors and R410A refrigerant with the Green VRF (GRV) air conditioning system a cutting-edge solution for energy savings, enhanced comfort, and intelligent operation across residential, commercial, and office projects.

As demand for advanced and energy-efficient air conditioning systems continues to grow, VRF (Variable Refrigerant Flow) technology has emerged as one of the most intelligent and efficient solutions for modern buildings. Green’s proprietary GRV VRF system incorporates dual full DC inverter compressors in capacities of 170,000 BTU/h and above, significantly improving energy efficiency, temperature precision, and equipment longevity.

Key Advantages of Dual Full DC Inverter Compressors

Precise Capacity Control

Each compressor operates independently and variably, allowing the system to continuously and accurately adjust cooling and heating capacities—eliminating the need for frequent on/off cycling.

Energy Savings

Inverter compressors reduce power consumption under partial loads and prevent peak demand spikes. The system only runs at the capacity required by the actual thermal load of the space, which leads to significant energy cost reductions.

Increased Reliability and Stability

Dual compressors provide system redundancy. If one compressor encounters an issue, the other can continue operating partially, ensuring uninterrupted performance and peace of mind.

Low Noise Operation

Thanks to soft start and continuous low-speed operation, inverter compressors generate significantly less noise—making them ideal for residential buildings and hospitals where quiet operation is critical.

Additional Benefits of Green VRF with Dual Inverter Compressors

•    Zone Control for individual area management and energy optimization
•    Flexible installation with extended piping lengths and multiple branch connections
•    Environmentally friendly R410A refrigerant
•    Optional BMS (Building Management System) integration
•    Stable operation in both high and low ambient temperatures

Design Considerations for VRF System Selection

To ensure optimal system performance and long-term efficiency, consider the following during system design and selection:
•    Evaluate the building’s actual thermal load to select appropriate capacity
•    Review software capabilities for system control and monitoring
•    Determine suitable outdoor unit placement with respect to ventilation and access
•    Follow the manufacturer's guidelines on refrigerant piping length and elevation difference

The Role of R410A Refrigerant in GRV7 Systems

One of the standout features of the 7th-generation GRV (GRV7) system is the use of R410A refrigerant, widely recognized for its superior performance in modern air conditioning systems, especially VRF. R410A offers high thermal efficiency, excellent compatibility with inverter compressors, and better flow characteristics due to optimal viscosity.

1. High Thermal Efficiency

R410A has a higher evaporation and condensation capacity compared to older refrigerants like R22, resulting in faster cooling and heating and better performance under partial loads.

2. Compatibility with Inverter Compressors

With its higher operating pressure, R410A aligns perfectly with inverter compressor technology used in VRF systems. This ensures precise temperature control and higher overall system efficiency.

3. Improved Flow Characteristics

Thanks to its better viscosity, R410A flows more smoothly through long refrigerant pipelines an essential benefit in VRF systems where piping distances are often extended.
Using VRF systems equipped with full inverter compressors is a modern and efficient solution for projects requiring stable, energy-saving, and controllable air conditioning. This integration optimizes system performance, reduces operating costs, and improves occupant comfort.
In markets such as Iran and many developing countries, R410A remains a strategic advantage in choosing a VRF system. The GRV solution from Green is an intelligent approach to energy optimization and indoor comfort.
