The magnetic suspension variable frequency centrifugal chiller (heat pump) unit is mainly composed of a magnetic suspension centrifugal compressor, evaporator, condenser, economizer, adjustable throttle valve, onboard frequency converter and automatic control system. The compressor uses magnetic suspension bearings, no lubricating oil is required, there is no need to worry about oil return restrictions, "0" friction, high efficiency, stable and reliable.
Xinlei magnetic bearings
Radial and axial integrated modular design, compact structure and stable performance;
No lubricating oil, zero friction, low power consumption, only 3~10% of conventional oil bearings, and the higher the speed, the more obvious the energy-saving effect;
Horizontally opposed impeller
Direct drive, no transmission loss,100%efficiency;
The impeller is horizontally opposed, and the axial thrust cancels each other out by more than 90%, with good self-balancing, low vibration and high reliability.
Impeller
The impeller adopts the optimization technology of CFD calculation + neural network + genetic algorithm to optimize the parameters under a wide range of working conditions to achieve high efficiency of both rated and partial load.
Control Cabinets
-PLC electronic control system, real-time monitoring of system operation data and trajectory, multiple protection and early warning;
-Internet of Things database management, the establishment of a background service platform, and modular management of equipment energy efficiency;
Magnetic levitation Centrifugal Compressor
-Two-stage compression, large surge margin, wider operating range;
-The impeller is horizontally opposed, and the axial force is small;
-Frequency conversion direct drive, low starting current, high unit efficiency;
-Magnetic bearing, running 0 friction, no attenuation of efficiency;
-Stepper motor + guide vane mechanism is built-in, with accurate mechanical limit and high reliability.
Flash Economizer
-The unit adopts two-stage compression and make-up gas enthalpy enhancement technology, which is 6% more efficient than that of single-stage refrigeration circulation system.
Intelligent Operator Panel
-Touch control screen, providing users with an intuitive interface, simple and convenient operation;
-Cloud remote monitoring, automatic fault alarm, easy to analyze the cause of failure;
Electronic Level Gauge
-Real-time monitoring of the liquid level, automatic adjustment of the throttle valve opening, to ensure the stable and reliable operation of the system.
High-efficiency Heat Exchanger
-The heat exchanger adopts high-efficiency heat exchange tubes, and the inner and outer walls are strengthened for heat transfer to obtain excellent performance;
-Optimize the structure of the heat exchanger to effectively improve the heat exchange efficiency.
The cloud platform can record and provide the operating status and operating parameters of the wind turbines bound to the platform, as well as perform fault alarm and data recording analysis. Users can log in to the platform to realize remote monitoring and energy-saving settings management, enabling users to realize real-time equipment management. At present, the IoT cloud platform provides ANDRIOD, IOS, and PC clients, and open interfaces to link with third-party software such as ERP, providing users with more possibilities.
