II. Product Features
High Energy Efficiency Ratio (EER/COP): The core advantage of DC inverter technology. The compressor speed adjusts dynamically based on actual cooling/heating demand, avoiding energy loss from frequent starts/stops, resulting in significantly higher efficiency than fixed-speed compressors.
Precise Temperature Control: Enables seamless speed control, minimizing temperature fluctuations for superior comfort.
Rapid Cooling/Heating: Can operate at high frequencies upon startup to reach the set temperature quickly.
Low Noise and Vibration: Smooth variable-speed operation eliminates the jarring start/stop cycles of fixed-speed compressors, leading to significantly lower noise and vibration.
Broad Operating Range: Capable of stable operation across a wider range of ambient temperatures.
This displacement class of DC inverter compressors is widely used in small to medium-sized refrigeration equipment demanding high efficiency and quiet operation:
