- High Efficiency: IPLV 30%+ higher than traditional units, drastic reduction in long-term electricity bills.
- Zero Contamination: 100% oil-free, zero risk of contamination. Meets strict environmental and green building standards.
- Rapid Deployment: Modular design, "plug and play" installation. Shortens project duration and installation complexity.
Core Technologies
Features active magnetic bearing technology to eliminate mechanical friction losses, boosting system energy efficiency by over 30%.
Employs a direct-drive configuration between the motor and compressor impeller—eliminating the need for speed-increasing gears—to achieve high power density, a compact footprint, a design efficiency exceeding 98%, and stepless speed control.
Boasts an efficiency exceeding 83%, offers a high single-stage compression ratio, and features a wide range of high-efficiency operation.
Utilizes advanced "V" or "W" shaped high-efficiency finned/micro-channel heat exchangers, characterized by a large heat exchange surface area and strong corrosion resistance.
Working Principle
The unit compresses refrigerant to a high-pressure state using a maglev centrifugal compressor, then dissipates heat through an air-cooled condenser using forced outdoor air circulation. In heat pump mode, the system switches cycles via a four-way valve to extract heat from the outdoor air and transfer it to the indoor water system. Magnetic bearings ensure zero-contact operation at high rotational speeds, while all-variable frequency technology enables precise power adjustment based on ambient temperature and load demand.
