Embodiment 1

[0024] Embodiment 1, this embodiment proposes an air conditioner fault auxiliary rapid diagnosis control method, such as figure 1 shown, including the following steps:

[0025] The air conditioner constraint encoding step is to encode various constraints when the air conditioner is running;

[0026] In the step of displaying the constraint type, during the operation of the air conditioner, when the air conditioner has an abnormal change in the operating frequency of the compressor due to the constraint, find out the constraint that causes the abnormal frequency change, and control the corresponding display device to display according to its code. The auxiliary rapid diagnosis and control method for air conditioner faults in this embodiment makes full use of the constraints and control conditions that air conditioners generally have at present. Since the generation of constraints is necessarily related to the faults of certain links of the air conditioner, this method uses , t...

Abstract

The invention discloses an air conditioner fault auxiliary rapid diagnosis control method. The air conditioner fault auxiliary rapid diagnosis control method comprises the following steps that air conditioner constraint coding is conducted, wherein various constraints during running of an air conditioner are coded; constraint type displaying is conducted, wherein during running of the air conditioner, when the running frequency of a compressor of the air conditioner becomes abnormal due to the constraints, the constraint causing the abnormal change of the frequency is found, and a corresponding displaying device is controlled to conduct displaying according to coding of the constraint. According to the air conditioner fault auxiliary rapid diagnosis control method, current common constraint control conditions of the air conditioner are utilized fully, due to the fact that necessary relation exists between constraint producing and faults in some links of the air conditioner, before the air conditioner breaks down, in other words, the frequency of the compressor changes due to the constraint condition, the type of the constraint can be displayed in a coding mode, and technicians can check the type of the constraint conveniently and can quickly position the fault.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to an air conditioner fault auxiliary rapid diagnosis control method. Background technique [0002] With the increasing popularity of air-conditioning, from cities to rural areas, the utilization rate of air-conditioning has been rising year after year, resulting in more and more after-sales complaints and defects. Due to the uneven technical level of air-conditioning after-sales personnel, relevant users have returned and exchanged machines and Bringing huge property losses, how to assist the after-sales personnel to quickly judge the method of the cause of the failure is the technical problem mainly solved by the present invention. Contents of the invention [0003] In order to solve the problem that it is difficult to quickly locate the fault when the existing air conditioner fails, the present invention proposes an auxiliary rapid diagnosis and control me...
