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 COP and EER.
- Smooth speed ramp up & down for the compressor control, low vibration and noise while the compressor starts up
with very low 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 power 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 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 rotation reversed.
- 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.
- Stability of high voltage.
- Current profile of compressor & fan.
- High temperature alarm of IPM & compressor & fan.
- L/N/C to UART.
- Wifi communication.
- Blue Tooth/ Zigbee/ Z-wave.
- PLC communication.
- First operation time.
- Total operation time.
- Unstable AC supply voltage.
- Abnormal operation current.
- Refrigerant leakage.
- Communication fail.
- Compressor control by low drive voltage (MTPA/MEPA).
- Effectively reducing power consumption of IPM by well design of heat-sink and placement.
- Maximum reducing the required stable power to maintain the indoor temperature.
Cool Down Air Flow
- Acrylic resin coating against water, insect and static.
- Surge protection.
- Enlarge cross-section area of high current circuit.
- Reduce weight by using small inductor of PFC.
- Control box improved to block the heat source and prevent the spread of naked flames.
