Dynamic Pressure Air Suspension Variable frequency centrifugal waterchiller

Dynamic Air Suspension: Innovative multi-simply sup-ported beam-type dynamic pressure air floating bearing,longer start-up life, up to 300000 times. No additionalmagnetic support is required before start-up, reducing thecomplexity of the magnetic system;

Ultra high speed permanent magnet synchronous motor technology: aero-space grade high-temperature alloy materials and processes; The motor hashigh power density, small size, light weight, compact structure, high-speeddirect drive, no need for speed increasing gears, avoiding loss of mechanicaltransmission efficiency and achieving higher motor efficiency; No mechanicalfriction, reducing mechanical wear; Longer service life and lower operating noise;

Oil free system, higher efficiency: Traditional chiller compres-sors are lubricated with oil. During operation, frozen oil accu-mulates on the surface of the evaporator, forming an oil filmand increasing thermal resistance, which may reduce heattransfer efficiency by 5-10%. Nuobing gas suspension unitsuse oil-free compressors to permanently avoid oil accumula-tion.

Wide adjustment range: The compressor is designed with highefficiency and wide operating conditions, and can achieve awide adjustment range of 10-100% through the combined ad-justment of speed and IGV.

Variable frequency regulation for more stable water temperature; Compared with traditional fixed frequency chillers, variable requency
chillers achieve perfect matching with the current actual load by changing the operating frequency and adjusting the refrigeration ca-pacity of the chiller, and the water temperature remains constant at the set value + 0.1 °C; Especially suitable for process projects with
high precision requirements for inlet water temperature;

Falling fim evaporator: a specially designed guide plate that can direct the condensed liquid refrigerant from the upper part of thetube array to both sides of the cyinder wall, fuly utilizing each heat exchanger to ensure thorough condensation and liquefaction,and maintaining sufficient liquid subcooling.

Control system: Adopting international advanced industrial grade German brand Siemens PLC controller and domestic first-line brand frequency con-verter. Intelligent and accurate, truly achieving perfect control of the entire machine, thereby ensuring the safe operation of the unit and achieving effec-tive energy saving. The color touch screen human-machine interface is easy to use, user-friendly, and can switch between automatic and manual control at will.

Cloud platform data intelligent control:Remote monitoring and operation of equipment, in case ofunit failure, professional service personnel from the manufac-turer can remotely diagnose and adjust the operating status;Realize the most intimate tracking service; And it can realizeOTA remote update program, and achieve the most perfectintelligent control through iterative program.
