- product introduction:G0280A compressor is an efficient oil-free refrigeration compressor specially developed by our company for the green and environmentally friendly refrigerant R134a. It can be used in comfort air conditioning chillers and commercial chillers. G0280A air suspension centrifugal refrigerant compressor consists of impeller, diffuser, volute, air bearing, motor, seal, etc. The compressor adopts a mature and reliable closed structure, and the two-stage compression adopts a symmetrical arrangement of impellers in the back direction, which is conducive to balancing the aerodynamic axial force and improving the bearing life. The motor is a permanent magnet synchronous motor cooled by refrigerant, and the cooling effect is not affected by the external environment. By changing the output frequency of the power supply through a frequency converter, the motor speed can be adjusted to achieve stepless speed regulation of the compressor. The motor rotor directly drives the impeller, eliminating the gear speed increasing device of conventional centrifugal compressors, reducing mechanical losses, and improving compressor efficiency. Friction connection is used between the rotor and impeller to avoid stress concentration, dynamic imbalance, and other issues, resulting in higher reliability. In addition, the compressor adopts dynamic pressure air bearing, which relies on the high-speed rotation of the rotor to form an air film, without the need for lubricating oil or additional gas supply system, resulting in smaller friction losses. The special bearing form and drive structure reduce the size of the G0280A air suspension centrifugal refrigerant compressor by more than 25% compared to traditional conventional compressors of the same capacity. The chiller products equipped with this compressor have energy efficiency far exceeding the national standard requirements and noise levels below 75dB (A).
