Embodiment Construction
[0052] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with the present invention. Rather, they are merely examples of apparatuses and methods consistent with aspects of the invention as recited in the appended claims.
[0053] figure 1 It is a flow chart of a method for judging the abnormality of the control board of the indoor unit according to an exemplary embodiment, as shown in figure 1 As shown, the method includes:
[0054] Step S11, obtaining the operating parameters of the indoor unit;
[0055] Step S12, according to the acquisition of the operating parameters, determine whether the indoor unit is ab...

The invention relates to an indoor machine control main board abnormity judging method and device, an air conditioner outdoor machine and an air conditioner unit. The method includes the steps that running parameters of an indoor machine are acquired; according to the acquiring condition of the running parameters, whether abnormity happens to the indoor machine or not is determined, and when it isdetermined that abnormity happens to the indoor machine, the abnormity is graded; and according to the grading, whether abnormity happens to an indoor machine control main board or not is determined.According to the technical scheme, when it is determined that abnormity happens to the indoor machine, the abnormity is graded, whether abnormity happens to the indoor machine control main board or not is determined according to the grading, and therefore it is achieved that when the indoor machine breaks down, accurate positioning about whether the indoor machine control main board is abnormal or not is achieved, after-sale maintenance can be conveniently guided, it is avoided that after-sale personnel replace the indoor machine control main board mistakenly, and the after-sale maintaining cost of an air conditioner is lowered.
Description
technical field [0001] The invention relates to the technical field of air conditioning, in particular to a method and device for judging the abnormality of an indoor unit control main board, and an air conditioning unit. Background technique [0002] Multi-connected central air conditioner is a type of household central air conditioner, commonly known as "one-to-many", which means that one outdoor unit is connected to two or more indoor units through piping. A primary refrigerant air conditioning system in the form of direct evaporative heat exchange. Multi-connected systems are currently being increasingly widely used in small and medium-sized buildings and some public buildings. [0003] In the after-sales maintenance of multiple units, the maintenance personnel often cannot directly distinguish whether the failure of the indoor unit is the damage of the control board or other reasons. In the end, the maintenance personnel directly replace the control board, resulting in...
