Smart Era

High Efficiency EVI Scroll Type DC Inverter High Pressure Cavity Compressor

1. High-Efficiency EVI Control Technology

The high-efficiency EVI compressor was developed according to the VRF unit's requirements. Its 0~0420Hz adjustable range perfectly matches the entire unit, enhancing performance to the greatest extent.

2. Release Valve

Improving partial load energy, adapting to the condition of the variable pressure ratio, and 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, can realise parallel connections of compressors with different delivery capacities and revolving speeds.

6. High Speed

0~420Hz stepless inverter operation, the 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 compressor's revolving speed and 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, lightning, and snow prolongs its service life and suits 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. This structure allows 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 a new grille design, the GMV6 outdoor airflow has increased by 16%.

The outdoor fan is also rated at 110Pa to allow the fitting of a diversion cover. It has a wind prevention function and can run backward 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 to increase the number of nodes in a single system by 56% and shorten the communication cycle, the preferential and centralised control response times, to seconds.
