Haier magnetic levitation central air-conditioning energy-saving industry NO.1

Recently, the 22nd International Refrigeration Exhibition opened in Shanghai. As one of the largest professional exhibitions in the HVAC industry in the world, this exhibition has attracted the participation of more than a thousand refrigeration companies and more than 10,000 guests. The highest technology and most innovative products in the industry are gathered here, and they also send people a feast for the future of refrigeration technology.

At the exhibition site, Haier, the leading brand in the central air-conditioning industry, exhibited the most energy-saving magnetic levitation products in the central air-conditioning sector so far. The product has been creatively applied with magnetic levitation technology, oil-free lubrication technology, precise frequency conversion control technology, and no fluorine. New refrigerant technology, high-efficiency heat transfer technology and many other international leading technologies have an overall energy efficiency ratio of 8.87, the highest in the industry. In addition, the product also has stable performance, long service life and other performance characteristics, has become the first choice for the energy-saving replacement of large areas such as hotels, rail transit, government public buildings, and brings people accurate energy-saving solutions.

Innovative technology creates "first energy-saving competitiveness"

It is reported that Haier central air-conditioning is currently the only domestic manufacturer of magnetic levitation central air conditioners independently developed and put into use, and is taking the lead in technological innovation of magnetic levitation centrifuges in the industry. The magnetic levitation compressor adopts magnetic levitation and variable frequency drive technology. The unit adopts oil-free lubrication. The refrigerant adopts the new refrigerant R134a with an ODP value of 0.

The series unit fundamentally improves the operating efficiency and performance stability of the centrifugal central air conditioner; the built-in digital electronic equipment can proactively monitor the operation of the compressor and provide comprehensive performance and reliability for the peripheral control and network monitoring. The information allows the user to "get in mind" about the operation of the machine; at the same time, the magnetic suspension compressor is also creatively applied oil-free lubrication technology, which can avoid the oil film covering the heat exchange tube in the shell-and-tube heat exchanger, resulting in reduced heat exchange efficiency The impact will increase the efficiency by more than 15%. In addition, the product also uses international advanced anti-surge technology. When the centrifugal compressor reduces the load to a certain extent, the compressed gas will form on the non-working surface of the impeller. The detachment group causes a sharp increase in the impact loss, which not only increases the flow loss and reduces the efficiency, but also causes the air flow to fall back from the pipe network to the compressor, causing a strong oscillation of the fuselage, and the anti-surge technology applied by Haier can be reasonable. Avoid this deficiency and reduce the occurrence of security incidents.

Through the application of a number of innovative technologies, Haier Maglev central air conditioners have achieved outstanding performance in energy-efficient, stable operation and long service life. According to monitoring data, compared to traditional products, the energy efficiency of Haier Maglev air conditioners is as high as 50%, and the equipment is used. With a lifetime of up to 20 years, it is the first choice for energy-saving replacement.

Detailed plan to create "excellent engineering suppliers"

Practice is the best standard for testing product performance. Haier Maglev central air-conditioning, which has significant energy-saving advantages, has been well used in many areas such as subways, real estate, and large hotels, and has been highly recognized in the industry. It is reported that monitoring data released by Kaifu Jianguo Hotel in Zhengzhou shows that after two years of operation monitoring data, the Kaifu Jianguo Hotel that uses Haier magnetic suspension centrifuges can save 50% in electricity bill per month compared to hotels with similar area and cooling load. Half the power. Therefore, if calculated according to the market demand of 280 million kilowatts, air conditioning for 8 hours per day and 200 days per year, Haier magnetic levitation centrifuges can achieve a saving of 90 billion kWh, which is equivalent to the annual power generation of the Three Gorges Power Station, and truly achieves high efficiency and energy saving.

Industry experts said that magnetic levitation centrifuge technology has once again widened the innovation time difference in the industry. Through the advantages of high-efficiency, energy-saving, stable motion, and long service life, it has strengthened the energy-saving and high-efficiency connotation of its own products and has truly realized the high efficiency and energy saving of air conditioners.
