Water-Cooled Air-Bearing Centrifugal Chiller Unit

Product Introduction:

The OYRR Water-Cooled Air-Bearing Centrifugal Chiller represents a revolutionary product embodying the cutting-edge technology of today's HVAC industry. Centered around an oil-free air-bearing centrifugal compressor, the rotor relies on the aerodynamic buoyancy of gas for support during operation, achieving absolute zero contact with the stator. This entirely eliminates the metal friction and lubricating oil system thermal resistance found in traditional compressors, allowing the equipment to maintain ultra-high energy efficiency throughout its lifecycle. This unit not only meets national Class 1 energy efficiency and 3-star Green Building standards but serves as the ultimate cooling solution for data centers, precision manufacturing, and large green commercial buildings striving for "Dual Carbon" goals and ESG transformation.

Features:

Dual High Efficiency (COP/IPLV): Utilizes a highly efficient three-dimensional flow impeller and a high power density Permanent Magnet Synchronous Motor (PMSM). Under specific conditions, COP can reach 6.2-6.8, and the Integrated Part Load Value (IPLV) soars to 12-15, far exceeding industry standards.

100% Oil-Free Design & Zero Degradation: No lubricating oil circulation in the system, eliminating thermal resistance caused by oil films on heat exchanger surfaces (a 3.5% oil content in traditional units reduces efficiency by 8%). It truly achieves "zero degradation" in operating efficiency and saves 30%-50% in annual maintenance costs.

70dB Ultra-Quiet Operation: Moving parts are fully levitated for frictionless operation, reducing structural vibration to near zero. Overall operating noise is as low as 70dB(A), eliminating the need for cumbersome shock absorbers or expensive soundproof plant rooms.

Ultra-Fast Restart & Loading: Designed specifically for uninterruptible cooling demands. After a power outage recovery, it takes as little as 45 seconds to rapidly restart and ramp up to pre-outage load conditions.

Long service life:The use of air-suspended bearings with no mechanical contact design ensures that there is no frictional loss between the bearing and the rotating shaft during operation. This fundamentally avoids the wear problems of traditional mechanical bearings and significantly extends the service life of the core components of the unit. The unit operates with minimal vibration, low noise, and no oil lubrication system, effectively reducing the failure rate and maintenance frequency, ensuring long-term stable and reliable operation of the unit, significantly enhancing the value of the equipment throughout its life cycle, and providing long-term, stable, and low-decay refrigeration guarantees for large-scale commercial and public building projects.

Application Scenarios:

Data Centers & Telecom Base Stations: Meets the strict PUE requirements of high-density heat-generating server rooms, adapting to rigorous 24/7 year-round cooling demands.

Green Commercial Buildings: Ideal for Premium Grade A office buildings, large commercial complexes, airports, and rail transit hubs pursuing green building certifications (LEED/WELL).

Advanced  Industrial Cooling: Semiconductor wafer fabs, precision instrument workshops, and pharmaceutical R&D centers highly sensitive to temperature fluctuations and equipment vibrations.

Our Advantages:

Advanced Core Technology: Adopts X-type foil aerodynamic bearings compliant with automotive GB/T 31467.3 standards. It requires no external gas supply system or complex magnetic levitation control systems, rendering it immune to sudden power outage risks

Automated Self-Cleaning System (Optional): Innovatively equipped with an automatic online physical cleaning device (sponge ball cleaning system) that continuously scrubs the inner walls of copper tubes with the water flow, keeping the heat exchanger at peak efficiency permanently.

Full Life-Cycle Cost Reduction: No oil changes, no oil filters, and no oil quality testing required, providing an incredibly simplified O&M experience for high-end clients globally and domestically.
