Summary:A method for protecting air-conditioner components of a bus comprises: connecting the main power of a bus with a voltage detection circuit capable of detecting the output voltage of a main power, and capable of transmitting the detected signals to an operation processing circuit to perform an operation processing, in which the operation processing circuit transmits a processing signal to a control circuit when the output voltage is lower than a normal voltage 24V to a specified low voltage value in order to cut off the power supply to the main power supply circuit of an electromagnetic clutch for connecting the engine and the compressor in an air conditioner system, so that it won't happen that the transmission plate of the electromagnetic clutch and the clutch press plate can not engage with each other due to an insufficient voltage and generates high heat due to the occurrence of relative friction. The production of high heat may thermally damage the electromagnetic coil on the transmission plate. This will
