Contact wear is a core issue affecting the reliability of air conditioning compressors during frequent start-stop cycles.
Troubleshooting such problems requires a comprehensive analysis from multiple dimensions, including contact status, coil control, mechanical structure, and external environment. Systematic testing and targeted repairs are necessary to restore the equipmen
In modern building HVAC systems, the start-up and shutdown control of high-power loads such as compressors, fans, and electric heaters relies heavily on a seemingly ordinary yet crucial low-voltage electrical component—the Siemens AC contactor.
The optimization of auxiliary contacts for AC contactors in air conditioning compressors needs to take into account mechanical performance, electrical performance, and intelligent requirements.
In modern residential and commercial air conditioning systems, the AC contactor for air conditioning compressors is a core power component, and its operating status directly affects the overall performance and energy efficiency of the unit.
In air conditioning systems, the compressor, as a core power component, generates a surge current far exceeding the normal operating current upon startup.
