Magnetic Levitation Centrifugal Chiller Hi-Magi AP Series

High Efficient Compressor

High Efficient Compressor: Inverter Centrifugal of Two-stage Compression Semi-hermetic Magnetic Leviation

Efficient Pneumatic Design

Pneumatic Efficiency of Compressor Improvement:

Equipped with full-fow high-efficiency pneumatic simulation optimization technology to control the flow field.

High-efficiency Closed Impeller:

Equipped with 3-Dimensinal closed impeller to ensure the accuracy of

pneumatic analysis through repeated comparison and correction between CFD analysis and sample unit testing results.

Power Consumption Reduction:

Equipped with 2-stage compression and vapor injection technology, the economizer can achieve adaptive intermediate supplementary cooling. In cooperation with optimized intermediate air intake and pneumatic design to achieve 6% energy reduction compared to single-stage compression.

Magnetic Levitation Bearing

Low consumption:

The magnetic levitation bearing is composed of one set of radial and axial magnetic bearings at both ends and position sensors in the middle, with a power consumption as low as 0.3 kW.

No friction:

The rotating shaft operates in suspension, with no direct contact with the bearings, eliminating mechanical friction losses.

Zero Degradation:

Oil-free design during unit operation eliminates the impact of lubricating oil on energy efficiency and ensures the long-term operation performance without degradation.

Precise Bearing Control System

Dynamic Monitoring Frequency > 10000 Times / S:

The Bearing Controller MBC actively controls the rotor position with a frequency of over 10000 Times / S. Micron-level high-precision position sensors monitor the rotor position to ensure precise suspension and rotation.

Shaft Imbalance Monitoring:

Vibration compensation function actively monitors the imbalance of the rotor. High damping characteristics can withstand instantaneous high load changes.

Power Off Protection System

Power Off Protection Process:

Equipped with self-generating motor,high-strength backup bearings and dual emergency power protection system, the motor of Hi-Magi AP Series can achieve auto-switching to generator mode and ensure continuous power supply of magnetic bearings to keep the rotor staying in a normal leviation state.

High-Strength Backup Bearing:

Hi-Magi AP Series units are equipped with one set of high-strength backup bearings at both the front and rear of the motor, which can absorb the impact of the motor shaft during a sudden power outage, protecting the magnetic levitation bearing, sensors, and other components from damage.
