8 Unique Features of BD Air Conditioner
AI INVERTER Technology
- Predict the torque shortage & over speed of the compressor to react the torque compensation correspondingly.
- More adaptive (than the Parametric control) by introducing the Auto-Learning & torque compensation to the compressor control for optimal coefficient of performance (COP) and energy efficiency ratio (EER).
- Smooth speed ramp up & down for the compressor control, low vibration and noise while the compressor starts up
with a very low rotation speed (RPS).
- Fuse built inside the AC power terminal block and could be triggered to protect the machine if overheat occurred due to inrush current or the terminal block not fastened well.
- No power supplied from DC to capacitor while the power is switch off; high voltage is discharged to ensure the safety of maintenance also extend the lifetime of capacitor.
- Power Factor Correction could be adjusted based on the needs to stabilize the compressor control and enhance the power factor.
- Fault Alarm sending to micro control unit (MCU) while temperature & current of motor or compressor is abnormal, and the unit will take protective actions immediately.
- Fuse will be triggered to avoid countercurrent back to the unit while the fan runs in reverse.
- Control refrigerant flow on optimal amount to achieve better efficiency via electric expansion valve.
- White noise detection algorithm.
- Numerical Simulation on flow turbulence reduction of indoor/outdoor fan.
- Very low noise at the very low speed mode of compressor and indoor/outdoor fan.
- L/N/C to UART.
- Wifi communication.
- Blue Tooth/ Zigbee/ Z-wave.
- PLC communication.
- First operatiing time.
- Total operating time.
- Unstable AC supply voltage.
- Abnormal operation current.
- Refrigerant leakage.
- Communication failure.
- High voltage stability.
- Current profile of compressor & fan.
- High temperature alarm for the interior permanent magnet (IPM) & compressor & fan.
- Compressor control by low drive voltage (MTPA/MEPA).
- Effectively reducing power consumption of the IPM by well design of heat-sink and placement.
- Maximum reducing the required stable power to maintain the indoor temperature.
