Basic knowledge of refrigeration compressor

After shutting down, stop for at least 3 minutes before starting again to eliminate the pressure difference between the compressor inlet and outlet. Because in the case of a large pressure difference, the starting torque of the motor will increase, causing the current to rise to a certain level, the protector will act and the compressor cannot continue to run.

Why is the refrigeration compressor always overheating protection?

Compressor overheating protection means to protect the compressor motor from being burned. When the motor temperature or the compressor's own temperature exceeds a certain value, some built-in or external protection devices are used to disconnect the compressor's working power supply to achieve protection The role of the compressor.
