origin

The core of maglev air conditioning lies in the magnetic fieldsuspensionCentrifugal compressor.Magnetic levitation air conditioningThe earliest research on magnetic levitation centrifugal compressors began in 1993 with the R&D of MULTITACK (Jiefeng Group) in Melbourne, Australiadepartment.Developed byengineerDr. Ron Conry led the TURBOCOR research team, which lasted for 10 yearsstudyThe world's first magnetic levitation centrifugal compressor was officially launched in 2003. In the same year, MULTISTAR Australia factorysuccessDeveloped the world's first maglev air conditioner, and in the same yearAmericaThe Chicago&ASHRAE/AHR exhibition was launched and won the Energy&Innovation Award.

Through high temperaturehigh pressureThe refrigerant is discharged from the air conditioning compressor, enters the condenser, releases heat to the copper tube cooling water, condenses into medium temperature and high pressure refrigerant liquid, and then passes through the shut-off valve to reduce the pressure and enter the low-temperature and low-pressure liquidevaporatorIn the evaporator shell, heat is absorbed from the chilled water flowing through the copper tube, vaporized into low-temperature and low-pressure gas, and then sucked into the compressor. After secondary compression in the compressor, it is discharged as high-temperature and high-pressure gas. Through this cycle, the ultimate goal of cooling is achieved.

Technical positioning

Magnetic levitation technology - utilizing permanent magnetic bearings and positioning sensorsmagnetandelectromagnetThe CNC magnetic bearing system consists of radial bearings and axial bearings, which enable the moving parts of the compressor to be suspended on the magnetic lining without friction. The positioning sensor on the magnetic bearing provides ultra high speed real-time repositioning for the motor rotor to ensure precise positioning.

Advantages of air conditioning

1. Compared to traditional chillers, the operating cost is reduced by 50%. Due to the 100% oil-free design, there is no lubricating oil in the refrigeration system, and the surface of the heat exchanger does not form an oil film that hinders heat transfer. This provides evaporation temperature in the evaporator and reduces condensation temperature in the condenser, greatly improving the efficiency of the refrigeration unit; Without lubricating oil, without the consumption of oil pump power, without the energy consumption of lubricating oil heating, and without the cooling consumption of lubricating oil cooling, the efficiency of the unit has been greatly improved.

2. Maintenance free, greatly saving maintenance costs. 100% oil-free design, without lubricants, no need to replace lubricating oil, no need to replace oil filters, no need to regenerate refrigerant in evaporators, greatly reducing maintenance costs

3. Environmentally friendly maglev air conditioners can use environmentally friendly R134a refrigerant, which has zero damage to the ozone layer; And the noise during operation is very low

4. Advantages in service life: Magnetic levitation bearings have no wear and tear, and the air conditioner has a service life of up to 30 years

development history

After 2003, with the emergence of magnetic levitation centrifugal compressorsThis means that the refrigeration and air conditioning equipment industry has entered a new era of magnetic levitation. In 2005, China's first maglev air conditioner was installed at MULTISTARChinaThe Guangzhou production base was established, and the following year, Haier's magnetic levitation air conditioner was also successfully developed and released at the Shanghai China Refrigeration Exhibition, gaining recognition in the industrybroadPay attention.

In the 10 years after 2003, the market capacity of maglev central air conditioning was relatively small, but the companies involved gradually clarified their development direction, represented by McQuay and Haier. Under their promotion, maglev central air conditioning products gradually took steps in the Chinese market. With the increasing promotion of the national 13th Five Year Plan for energy conservation and emission reduction policies, the market has a growing demand for maglev air conditioningThe surge in demand has attracted major maglev production companies from around the world to increase their investment in the Chinese market, such as MULTITACK, McQuay, etc. The maglev air conditioning industry has thus formed a situation of fierce competition among the top players.
