Magnetic Bearing Central Air Conditioning
Xinran magnetic bearing central air conditioning system uses magnetic bearing technology to achieve oil-free operation. Compared with a conventional screw unit, it reduces energy consumption by over 50%, while keeping operating noise at or below 77 dB. The central air conditioning system offers a service life of 25 to 30 years, making it suitable for large public buildings and industrial applications where energy efficiency, low noise, and long-term operating stability are important.
- Commercial buildings
- Industrial plants
- Large venues
- Healthcare facilities
- Office spaces
- Hotels
- Restaurants
- Transportation hubs
The magnetic bearing central air conditioning regulates indoor air conditions through an advanced cooling and heating system, providing precise control of temperature and humidity. The system consists of the compressor, evaporator, condenser, and control system. With a low operating noise level of ≤77 dB, it is suitable for public environments, such as:
