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.
