High-end quality and core technology for LG water-cooled multi-line stability blessing
The continuous development of the economy has accelerated the pace of urbanization in China and promoted the development of first-tier cities to international metropolises and second- and third-tier cities to first-tier cities. While vigorously developing everywhere, the state has attached great importance and support to environmental protection work. Since the launch of the new concept of green development in the “13th Five-Year Planâ€, the environmental protection and energy conservation efforts have increased. The Ministry of Housing and Urban-Rural Development, the National Development and Reform Commission and the General Administration of Quality Supervision, Inspection and Quarantine have successively issued relevant industry standards. Nowadays, the high-rise buildings that rise from the ground ensure the appearance of beauty while being energy-saving and environmentally friendly, and adopt a new material glass curtain wall.
Compared with the old concrete wall, the glass curtain wall has obvious environmental protection and lighting advantages, but it also causes the building insulation effect to be greatly reduced. Especially in long-term hot and humid areas such as East China and South China, the problem is more obvious, and the central air-conditioning system with stable performance is becoming a high-rise. The key factor in maintaining a constant temperature in the building.
Hardware-enhanced high-precision technology
As the land resources of various cities become more and more scarce, the buildings around the city are getting higher and higher, and at the same time, more and more projects for the aesthetic effect of the building adopt the appearance of the all-glass curtain wall; It is said that the ventilation space of the outdoor unit is difficult to guarantee, and the gap between the indoor and outdoor machines is also increasing, which results in a drastic reduction in the operating efficiency of the multi-line system, and the most direct manifestation of this phenomenon is the annual air-conditioning operating cost. The rise. With the large-scale promotion of water-cooled multi-line system, you don't have to worry about this problem in the future. Let's take a look at why LG water-cooled multi-connection can provide you with efficient and stable air-conditioning system.
LG water-cooled multi-connection In order to ensure the safe, stable and efficient operation of the system, its plate heat exchanger adopts Alfa Laval plate heat exchanger from Sweden; the cooperation of top brands ensures the quality of top water-cooled multi-line; The high COP provides a solid guarantee, and its high pressure capacity (4.5MPa) ensures that the LG water-cooled multi-line can be adapted to various types of water systems, and you can choose whether you are building a new building or an old building.
LG water-cooled multi-line through the unique technological innovation, can operate efficiently in the wide range of -5 to 45 degrees, through its unique variable water flow control technology provides more choices for energy-saving control of cooling water system operation . LG variable water flow control technology can directly control the proportional integral valve corresponding to the outdoor unit, so that the circulating water passing through the outdoor unit can be accurately matched with the operating capacity of the indoor unit; when the circulating water is adjusted in the range of 40% to 100%, the outdoor unit can still Efficient and stable operation;
Software supports core technology to ensure air conditioning lossless and efficient
LG water-cooled multi-line adopts the fourth-generation DC inverter compressor. The compressor frequency range is from 15Hz to 150Hz. The range of variation is wide and the starting speed is fast. When the load changes, the output of the press is evenly changed by changing the frequency of the press. Different needs to adjust the operating frequency, and the work runs smoothly.
At the same time, LG compressor adopts the patented technology of high pressure oil return. By improving the circulation loop, the head loss is lower, the resistance of the equipment is smaller, and the suction part is completely lost. The new oil separator is equipped with a redesigned new oil separator that increases efficiency by 50% and improves efficiency over the full operating range. The compressor is equipped with an oil level sensor as standard to ensure that the system returns oil on demand, reducing unnecessary oil return operation; with the top technology of variable water flow control and large capacity heat exchanger in the whole machine, the unit average cooling energy efficiency COP5. 5 (10HP benchmark), ensuring LG water-cooled multi-line operation with low energy consumption and high efficiency.
As early as 2014, LG Central Air Conditioning successfully bid for the “Guangzhou Window†project of Guangzhou landmark building with the advantage of water-cooled multi-line products. “Guangzhou Window†is the Guangzhou Zhongjiao South Headquarters Base. It is not only the key project of Guangzhou, but also the top 500 projects in Guangdong Province, with a construction area of ​​550,000 square meters and special humid weather in Guangzhou. It has extremely high standards for air conditioning systems. LG Central Air Conditioning Service Team adheres to the "customer first" service principle, conducts multiple on-the-spot investigations and in-depth understanding of the project, and finally applies 234 sets of water-cooled multi-connected on the 43-story building, and cooperates with DX-AHU fresh air system for customers. Provides the perfect air conditioning environment and service.
Now two years later, LG Central Air Conditioning's water-cooled multi-connected air-conditioning system tailored for the “Guangzhou Window†is still conveying fresh air smoothly, creating a comfortable office space. In the future, LG Central Air Conditioning Service Team will carry more water and cold. Online, to enter the market with industry benchmarks, continue to provide excellent air conditioning services to customers.
