Problems solved by technology

Since it is impossible to accurately identify whether it is the compressor or the controller that is faulty, the after-sales maintenance personnel cannot quickly identify the cause of the fault. The current common practice is to replace the parts to eliminate them one by one, and finally lock the faulty parts
However, due to the large number of air conditioner models and compressor models, the controller must be matched with the compressor to drive normally, which creates complexity for after-sales maintenance personnel.
When the controller does not match the compressor, it will also lead to misjudgment by maintenance personnel and increase maintenance costs

[0054] The embodiment of the present invention provides a driving fault detection method for quickly detecting the driving fault of the air conditioner 2 . see image 3 , is a flow chart of a driving failure detection method provided by an embodiment of the present invention. The drive failure detection method includes:

[0055] Step S301: Detect whether the preset condition is met, if yes, execute step S302; if not, execute step S301 again.

[0056] By detecting whether the preset condition is satisfied, it can be judged whether the maintenance mode can be entered.

[0057] In a preferred embodiment, the step S301 includes: detecting whether the first jumper end and the second jumper end are short-circuited, if yes, execute step S302; if not, execute step S301 again.

[0058] Specifically, when the first jumper end and the second jumper end are in the disconnected state, the controller 4 operates normally, and calls the pre-established normal compressor driving parameters ...

Abstract

The invention provides a driving fault detecting method and device and an air conditioner, and relates to the technical field of air conditioners. When a preset condition is met, an overhauling mode is started, then preset after-sales compressor driving parameters are called to drive a compressor simulation tool to run, and a driving fault detecting result is generated according to the running state of the compressor simulation tool; since the overhauling mode can be directly started through the short circuit of a first jumper end and a second jumper end or through composite buttons of a remote control unit, the compressor simulation tool is driven to run according to the preset after-sales compressor driving parameters matched with the compressor simulation tool, and therefore the drivingfault detecting result can be generated according to the running state of the compressor simulation tool; the whole operation process is convenient, the result is accurate, and meanwhile tools and accessories which need to be carried by overhauling personnel are high in versatility; not only can the problems of too many models of after-sales compressors and too many accessories during maintenancejudgment be solved, but also the situation can be avoided that the maintenance cost caused by misjudgment is increased.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a driving fault detection method and device and an air conditioner. Background technique [0002] Inverter air conditioners adjust the cooling capacity by adjusting the speed of the compressor, increase the cooling capacity when the temperature is far from the target temperature, and decrease the cooling capacity when the temperature is close to the target temperature, so that the room temperature can be stabilized at a comfortable level. In order to achieve precise control, the control of the compressor speed by the inverter air conditioner is a closed-loop control. It is necessary to detect the current speed of the compressor in real time and send the speed information back to the controller. The controller controls the output current according to the difference between the current speed and the target speed, so that The compressor speed reaches the established target ...
