1. High Efficiency and Energy Saving; Excellent Part-Load Performance
|
|||||||||||||
|
Utilizing two-stage compression or variable frequency drive (VFD) technology, the unit achieves a Coefficient of Performance (COP) exceeding 6.1 and meets the national Grade 1 standard for Integrated Part-Load Value (IPLV). Stepless capacity modulation is available across a 15%–100% load range; since the unit operates under part-load conditions for approximately 99% of its runtime with minimal efficiency loss, it saves 20%–30% in electricity compared to traditional centrifugal chillers.
|
|||||||||||||
| 2. Stable, Reliable Operation and Long Service Life | |||||||||||||
|
The centrifugal compressor features few moving parts, resulting in an average service life of 80,000 hours. The two-stage compression design offers a much wider operating range than single-stage models, making it less prone to surging. Certain models utilize oil-free magnetic bearing technology for frictionless operation, extending the service life to over 25 years; the absence of an oil system eliminates the need for oil changes and related maintenance.
|

| 3. Low Noise and Low Vibration | |||||||||||||
|
Operating noise for magnetic-bearing centrifugal chillers can be as low as 78 dB, making them ideal for noise-sensitive environments such as schools, concert halls, and museums. The oil-free design eliminates mechanical friction noise associated with traditional bearings and significantly reduces vibration levels.
|
|||||||||||||
| 4. Compact Structure; Easy Installation and Maintenance | |||||||||||||
|
The positive-pressure design reduces the unit’s footprint by approximately 35% compared to negative-pressure models, saving valuable mechanical room space. Units are factory-charged with refrigerant and lubricant, requiring only water and power connections for immediate startup. The evaporator is designed for easy cleaning without major overhauls; routine maintenance is limited to cleaning the water system.
|
|||||||||||||
| 5. Eco-friendly Refrigerants; Green and Low-Carbon | |||||||||||||
|
Uses environmentally friendly refrigerants such as R134a (ODP=0) or R1234ze. Magnetic-bearing models employ oil-free systems, significantly reducing refrigerant charge requirements and effectively lower carbon emissions.
