Air conditioning is a common household appliance in modern life. It can provide cool and warm for people's life in hot summer and cold winter. Now with the continuous progress of technology, magnetic levitation centrifuge has appeared in people's life.

Maglev centrifuge also calledmagnetic levitation central air conditioning. Now, with the advancement of technology,magnetic levitation centrifugeIt is favored by more and more enterprises.magnetic levitation centrifugeWhat the hell is it?magnetic levitation centrifugeWhat is the working principle?

The working principle of the magnetic levitation centrifuge is that the magnetic bearing and the positioning sensor use the radial bearing and the axial bearing composed of the permanent magnet and the electromagnet to realize the frictionless movement of the moving parts of the compressor suspended on the magnetic lining. The positioning sensor on the magnetic bearing is The motor rotor provides high-speed real-time repositioning to ensure accurate positioning.

The core technology of magnetic levitation centrifuge mainly includes high-speed oil-free magnetic bearing technology, new heat exchanger heat transfer technology, intelligent control safety protection technology, etc. Among them, the high-speed oil-free magnetic bearing technology makes the magnetic levitation oil-free operation, completely eliminates the contact between metal and metal, and will not wear the surface; the centrifugal compressor adopts high-strength aviation-grade alloy to ensure the stability and reliability of the impeller at high speed, Using two-stage compression technology, the compressor can operate stably in a larger range. At the same time, the unit adoptsDC frequency conversion technology, 2~100 stepless adjustment to optimize the energy consumption of the unit; high-speed permanent magnet synchronous motor, the efficiency within the operating range of the unit reaches 99%; direct drive technology has the advantages of long service life, low noise and low maintenance cost.

Heat exchanger heat transfer new technology can makemagnetic levitation centrifugeConvection heat transfer technology ensures uniform distribution of refrigerant and effectively improves the overall heat transfer efficiency.30%. The falling film evaporator has high heat transfer coefficient to ensure heat transfer stability; there is a large amount of refrigerant in the all-liquid evaporator, and the thermal shock of the machine is small; the maximum subcooling degree of the secondary subcooling technology can reach 15, and the cooling capacity of the system can be increased by 8%.

Precise level control technology,Adaptive refrigerant distribution under 0-110% refrigerating capacity to ensure stable operation of the system; Intelligent anti-surge technology effectively solves the problem that the regular centrifuge unit is easy to surge by adjusting the rotating speed and inlet guide vanes. Accurate temperature control technology can realize 0.1 changes in outlet water temperature, with small temperature fluctuation and high comfort. Sensorless vector frequency conversion control technology, starting current 2A, greatly improves the energy efficiency of the unit under partial load; In addition, emergency power-off protection and quick start function are also set up to make it safer to use. This is the intelligent control security technology.

　　magnetic levitation centrifugeSince its birth, it has been widely used and put into use in various industries and fields. Shopping malls, factories began to spreadmagnetic levitation centrifugeIt maintains a high-speed development trend every year, occupies the market share of commercial central air conditioners, and plays its own role in energy conservation and emission reduction of traditional projects.
