Air-Bearing Centrifugal Chiller

The Air-Bearing Centrifugal Chiller Unit is a high-capacity chilled water system designed for continuous cooling operation in medium and large-scale facilities. The system consists of an air-bearing centrifugal compressor, evaporator, condenser, expansion device and intelligent control platform. Compared with conventional centrifugal chillers using oil lubrication, the air-bearing structure removes the need for compressor oil, reducing oil-related maintenance and avoiding oil contamination inside the refrigeration circuit.

Lynxcool provides complete refrigeration solutions from equipment manufacturing to system commissioning. Based on project conditions such as cooling capacity, operating temperature, installation environment and control requirements, our engineering team can support customers with suitable chiller configuration and system integration.

Air-Bearing Compressor Structure

Oil-Free Operation Without Mechanical Contact

The compressor rotor is supported by an aerodynamic air film generated during operation, allowing the rotating components to run without direct mechanical contact. This structure eliminates the requirement for lubrication oil and reduces wear components inside the compressor system.

For facilities requiring stable operation with limited maintenance access, such as data centers, pharmaceutical production areas and industrial plants, the oil-free design helps simplify daily management and reduces potential risks caused by oil circulation.

Compact Centrifugal Compression Technology

The centrifugal compression system uses a high-speed impeller to increase refrigerant pressure efficiently. The compact compressor arrangement allows the chiller to achieve high cooling capacity while reducing equipment footprint compared with traditional large refrigeration units.

This design is suitable for projects where machine room space, transportation limitations or installation costs need to be considered during system planning.

Load Adjustment Through Variable Frequency Control

The integrated variable frequency drive adjusts compressor speed according to actual cooling demand. Combined with inlet guide vane regulation, the system can respond to changing loads during different seasons and operating periods.

This control method helps maintain stable chilled water output while improving part-load performance in applications with variable cooling requirements.

Refrigeration System Design and Control

Oil-Free Refrigeration Circuit

Because the compressor operates without lubricating oil, the refrigeration circuit avoids oil migration problems that may affect heat exchanger performance. The system requires less oil-related service work during operation and maintains cleaner heat transfer surfaces.

This feature is especially suitable for projects requiring continuous cooling operation and strict equipment reliability requirements.

Heat Exchanger Configuration

The chiller uses shell-and-tube evaporator and condenser designs selected according to application requirements. Enhanced copper tube technology improves heat transfer performance, while the removable tube bundle design allows easier inspection and cleaning during maintenance.

Intelligent Operation Management System

Lynxcool integrates an intelligent control system to monitor operating parameters including temperature, pressure, compressor status and system performance. The controller supports communication with building management systems through standard protocols, allowing operators to monitor equipment operation remotely.

FAQ

What is the main difference between an air-bearing chiller and an oil-lubricated centrifugal chiller?

The main difference is the compressor support structure. Air-bearing chillers use an aerodynamic air film instead of oil lubrication, which eliminates compressor oil management and reduces oil-related maintenance requirements.

Does the air-bearing centrifugal chiller require regular oil replacement?

No. The refrigeration circuit is designed for oil-free operation, so there is no compressor oil replacement procedure during normal operation.

What applications are suitable for this chiller?

The unit is suitable for large commercial buildings, district cooling systems, data centers, pharmaceutical facilities, industrial plants and other applications requiring stable chilled water supply.

Can Lynxcool provide complete refrigeration system solutions?

Yes. Lynxcool provides refrigeration system design, equipment manufacturing, installation, commissioning and after-sales support according to project requirements.

Can the chiller be integrated with a building management system?

Yes. The control system supports common communication protocols including Modbus and BACnet for connection with building automation systems.
