Abstract

The invention discloses a fault monitoring device and method, an air conditioning unit and an air conditioner. The method comprises the steps that a temperature detector detects current temperature values of all parts in the unit in real time, an early warning controller judges whether an early warning part exists according to a detection result, and if the early warning part exists, early warning processing is performed, wherein the current temperature value of the early warning part is larger than the upper temperature limit corresponding to the early warning part itself. According to the fault monitoring device and method, the air conditioning unit and the air conditioner, the current temperature of all the parts is detected, early warning processing is performed when the current temperature of the part exceeds the corresponding temperature threshold, and therefore passive processing of faults can be converted into active prevention of the faults.

Description

technical field [0001] The invention relates to the field of control, in particular to a fault monitoring device and method, an air conditioner unit and an air conditioner. Background technique [0002] At present, the electronic control components of large central air-conditioning units are often damaged due to factors such as short circuit, overload, or continuous high-temperature operation, and the components cannot be restored. In addition, the connecting wire used in the current electric control box may also have a small wire diameter or an excessively large resistance, which may cause the temperature to continue to rise, and eventually cause the wire to be overheated until it burns. The precursor to these failures is often abnormally high temperature. [0003] In order to overcome this defect, currently there is a way of detecting the temperature of the unit through a temperature sensor in the prior art for safety warning. But the working temperature of different par...
