NEW TECHINICAL AIR BEARING CENTRIFUGAL CHILLER

Core Energy-Saving Features of Air Suspension Chiller
The unit's core energy saving comes from the full-chain collaborative optimization of oil-free air suspension technology, two-stage centrifugal compression, high-efficiency frequency conversion and heat exchange system. Industry tests show it saves 30%-50% energy compared with traditional screw chillers, with key features as follows:

1. Permanent Magnet DC Inverter Drive, Leading All-Condition Energy Efficiency
Equipped with a high-efficiency permanent magnet synchronous inverter motor (efficiency ≥97%), it reduces drive energy consumption by over 10% vs. traditional fixed-frequency/ordinary asynchronous motors. At daily low loads (≤70%), the unit's COP has no obvious attenuation, with IPLV ≥10.0 (exceeding national first-class energy efficiency), adapting to industrial load fluctuations for normalized energy saving.
2. Two-Stage Centrifugal Compression, Lower Useless Heat Loss
Adopting a speed-type two-stage centrifugal structure (no rotor meshing friction), it minimizes useless heat during compression. Combined with a three-dimensional flow high-efficiency impeller (isentropic efficiency >92%), it has much higher energy utilization than traditional screw models, reducing work loss from the source.
3. Air Suspension Frictionless Structure, Zero Mechanical Loss
Aviation-grade dynamic pressure air suspension bearings form a high-pressure air film within 0.1s of startup, achieving complete rotor suspension. No mechanical contact/friction eliminates 7%-12% input power loss from traditional bearings, maintaining nearly 100% mechanical transmission efficiency at all speeds.
4. Oil-Free System Design, No Heat Exchange Resistance Loss
Oil-free compressor operation avoids oil film formation on evaporator/condenser tubes (which reduces heat exchange efficiency by 5%-10%), keeping the heat exchange system highly efficient and eliminating annual energy efficiency attenuation caused by oil pollution.
5. Falling Film Evaporator, Industry-Leading Heat Exchange Efficiency
Standard falling film evaporator sprays refrigerant to form a thin liquid film, avoiding boiling point elevation from static liquid level. Its efficiency is ~5% higher than flooded evaporators and over 50% higher than dry ones, with less refrigerant and faster response, further reducing heat exchange energy consumption.
6. Wide-Range Stepless Inverter Regulation, Precise Temperature Control
Supports 20%-100% stepless inverter regulation (temperature control accuracy ±0.1℃), matching cooling output to terminal demand in real time without frequent shutdowns. It avoids startup impact energy consumption and invalid energy loss from mismatched cooling output, achieving precise energy saving under all conditions.
