Centrifugal refrigeration compressor

Unit characteristics:

Ø Adopting a fluorine free new environmentally friendly refrigeration system that has no destructive effect on the atmospheric ozone layerR134a；

Ø The design of the compressor host adopts internationally advanced technologyNRECThe software was designed and combined with an efficient heat exchanger to achieve high refrigeration efficiency of the unit;

Ø The impeller adopts an efficient rear curved impeller, which is milled from a special aluminum alloy as a whole;

Ø The specially designed lubricating oil system combined with the control system can effectively ensure the bearing oil supply of the compressor during operation or sudden power outages, avoiding bearing oil shortage damage;

Ø Adopting a closed motor, the rotor and stator of the motor are cooled by refrigerant evaporation, effectively preventing the motor from overheating. This not only extends the service life of the motor, but also reduces its external dimensions;

Ø Advanced motor starting method (closed star)/Triangle start, multi-stage voltage regulation start, high-voltage direct start) reduce the starting current to protect the safe operation of the motor;

Ø By using an image touch screen and a specially designed microcomputer control system for the refrigeration unit, the safe operation of the unit is ensured, and the control logic can be optimized to improve operational efficiency;

Ø By adopting a dual adjustment method of imported guide vanes and variable blade diffusers, the range of cooling capacity adjustment has been expanded, allowing the unit's cooling capacity to operate at a constant inlet water temperature20%～100%Adjust arbitrarily within the range;

Ø Adopting high-precision and bi-directional tooth height and width modification, the transmission is highly translational. The gearbox adopts a dual sound insulation structure and a condenser inlet design with a noise reduction device to reduce the noise of the unit;

Ø The unit adopts a whole pry structure, with a novel and compact structural layout, small footprint, and easy installation and transportation.
