1. Functional Positioning
The variable frequency compressor is the core component of the refrigeration system. It controls the output capacity of the compressor by adjusting the power supply frequency to change the motor speed. It adjusts the refrigerant circulation volume in real time according to the system load demand to achieve precise temperature control and energy-saving operation.

2. Working Principle
Frequency conversion technology: Use the inverter to convert fixed-frequency AC power into variable-frequency AC power to drive the compressor motor.
Stepless speed regulation: Automatically adjust the compressor operating frequency (such as 30Hz-120Hz) according to parameters such as indoor and outdoor temperature and system pressure.
Capacity control: Adjust the refrigerant mass flow rate by changing the speed to avoid frequent start and stop of fixed-frequency compressors.

3. Product Features
Energy saving Compared with fixed-frequency compressors, energy efficiency is improved by 30%-50%, and the annual operating cost of some models is reduced by 40%.
Precise temperature control The temperature fluctuation range is ±0.5℃, avoiding the "hot and cold" of fixed-frequency compressors.
Low noise Stepless speed regulation reduces mechanical vibration and reduces operating noise by 5-10 decibels (such as 20 decibel silent mode).
Long life Reduce the number of starts and stops, and extend the life of the compressor by 2-3 times (design life exceeds 15 years).
Wide voltage adaptation Supports 180V-240V wide voltage operation to adapt to power grid fluctuations.
Fast cooling/heating The power is increased by 50% during high-frequency startup, and the set temperature is reached quickly.
