Fixed Frequency Air Source Heat vs Inverter Air Source Heat Pump

The main difference between fixed frequency and inverter air source heat pump lies in their working mode and energy efficiency performance:

1. Working mode

Fixed frequency air source heat pump: The compressor runs at a fixed speed, the switching frequency is high, and the temperature fluctuation is large.

Inverter air source heat pump: The compressor speed is adjustable, and the operating speed is automatically adjusted according to demand, and the temperature control is more precise.

2. Energy efficiency performance

Fixed frequency air source heat pump: Low energy efficiency, frequent start and stop, and high power consumption.

Inverter air source heat pump: High energy efficiency, stable operation after start, and significant energy saving effect.

3. Comfort

Fixed frequency air source heat pump: Large temperature fluctuations, relatively low comfort.

Inverter air source heat pump: Constant temperature, higher comfort.

4. Service life

Fixed frequency air source heat pump: Due to frequent start and stop, the compressor wears more and the service life is relatively short.

Inverter air source heat pump: Smooth operation, small compressor wear, and long service life.

Inverter air source heat pumps are superior to fixed frequency air source heat pumps in terms of energy efficiency, comfort and service life, but the price is relatively high. The selection should be based on specific needs and budget.
