On June 30, 2024, the Shenzhen-Zhongshan Corridor was officially opened to traffic, becoming the core project of building a comprehensive transportation system in the Guangdong-Hong Kong-Macao Greater Bay Area. After serving the Hong Kong-Zhuhai-Macao Bridge, Gree Central Air Conditioning once again provided HVAC equipment support for the Shenzhen-Zhongshan Corridor, a super-large transportation project in the Guangdong-Hong Kong-Macao Greater Bay Area, to promote the in-depth integration and development of urban agglomerations in the Bay Area.
Transportation powerhouse, the gateway to the Bay Area
The Shenzhen-Zhongshan Corridor is a major national project and a business card project representing China's national image, with a total length of about 24 kilometers and a total length of about 24 kilometers, after 14 years of preparation and construction, it has set a number of "world's best".
As one of the most difficult cross-sea cluster projects in the world today, the benchmark project for the development of new quality productivity in the transportation industry is an important symbol of the mainland's transformation from a transportation power to a transportation power. With the goal of "building a world-class sustainable cross-sea corridor and creating a century-old gateway project for the Greater Bay Area", the Shenzhen-Zhongshan Corridor has achieved a number of innovations and breakthroughs, and contributed to the world's cross-sea corridor project, Guangdong experience and Chinese solutions.
The LMV series inverter air-cooled screw unit manufactured by Gree Electric Appliances and serving the artificial island and management center of the Shenzhong Channel was officially put into use. The total installed capacity of the project is 2140KW, and the IPLV is as high as 4.0 or above, which meets the national first-class energy efficiency standard. The product can be widely used in large public buildings, hospitals, gymnasiums, hotels, shopping malls and other places.
China's intelligent manufacturing and strength escort
Gree adheres to the concept of independent innovation, under the structure of low-carbon energy, combined with the marine environment of the deep and middle channel, which is resistant to saline-alkaline climate corrosion, strong wind and waves. According to local conditions, the LMV series inverter air-cooled screw unit is specially designed and developed.
1. High-efficiency permanent magnet synchronous inverter compressor
The high-efficiency permanent magnet synchronous frequency conversion motor is adopted, with no excitation loss, and the average efficiency of the motor is more than 95%, and the maximum is 97.5%.
Variable frequency and variable capacity are controlled collaboratively, so that the pressure ratio and flow can be adjusted independently, without over-compression or under-compression, and the load is perfectly matched with the actual working conditions, which is energy-saving and efficient.
2. High-efficiency inverter
3. High-efficiency heat exchanger
The user side adopts a high-efficiency flooded shell and tube heat exchanger, which has good heat transfer performance; Low water flow loss and low pump energy consumption.
The V-shaped fin heat exchanger is used on the environmental side, with the best V-shaped angle, uniform flow distribution and high heat exchange efficiency.
Fourth, high-precision electronic expansion valve
The maximum 3810-stage stepper motor, the combination of coarse adjustment and fine-tuning, realizes precise flow control, improves the operating efficiency of deviation from working conditions and low-load working conditions, dynamically controls the superheat of the evaporator outlet, and improves the utilization efficiency of heat exchange area.
5. Low vibration and low noise design
It is equipped with special metal-rubber vibration isolators, sound insulation covers, etc., and adopts multiple noise reduction and vibration reduction measures, and the overall noise reduction is as high as 8-10dB(A).
Scientific and technological innovation is the core element in the development of new quality productive forces. In the process of serving the Shenzhen-Zhongshan Corridor project, Gree has carried out scientific and technological research, constantly updated the design plan, and also provided reference for subsequent service major projects.
With the opening of the Shenzhen-Zhongshan Corridor, Gree Central Air Conditioning will continue to help the construction of the Greater Bay Area with practical actions and contribute to the high-quality development blueprint of the Guangdong-Hong Kong-Macao Greater Bay Area!
