AI Technical Summary
When the rectifier module of the air conditioning unit malfunctions, the human-machine interface cannot be displayed, which prevents users from obtaining fault information in a timely manner and affects the efficiency of fault diagnosis and repair.
The system uses independent rectifier modules to power high-voltage and low-voltage loads respectively. When one rectifier module malfunctions, it will not affect the other rectifier module, ensuring that the human-machine interface can be displayed normally and that users can obtain the operating status and fault information in a timely manner.
It improves the fault controllability, operational reliability, and maintenance convenience of electrical equipment, ensuring that faults can be located and handled in a timely manner.
