Problems solved by technology

[0004] In the above-mentioned prior art, although the after-sales service system can judge the possible faults of the air conditioner by obtaining the operating parameters of the air conditioner online, and arrange the after-sales service in time, so that the activation of the after-sales service changes from passive to active, but this method also exists The following problems: customers can only find out the abnormal operation of the air conditioner after the fault occurs, and start the self-test program to wait for the after-sales maintenance personnel to come to repair the air conditioner, but the air conditioner cannot be used normally during the waiting period, which reduces the customer's experience of using the air conditioner

Embodiment 1

[0059] Judgment model of inverter air conditioner cooling mode, dirty filter or blocked evaporator:

[0060] During cooling operation, when ΔTin ≥ T_cool_1℃, and the freezing protection count ≥ 1, and all the following conditions are met at the same time, it is judged that the indoor filter or evaporator is dirty and blocked:

[0061] Condition 1: T_in≥T_cool_2℃; -Comparison and judgment of the current operating parameters of the single machine and the coupling correlation value

[0062] Condition 2: DSH≤DSH_cool_1℃; -Comparison and judgment of the current operating parameters of the single machine and the coupling correlation value

[0063] Condition 3: ΔTin 均值i -ΔTin 本机基准 ≥T_cool_3℃;-Comparison of the current operating parameters of a single machine and the benchmark operating parameters of the machine, where i is the current cycle order in the cycle sequence.

Embodiment 2

[0065] Inverter air conditioner refrigeration mode, refrigerant leakage judgment model:

[0066] If any of the following conditions are met, it is judged that the refrigerant leakage is in a relatively small stage:

[0067] ΔTin 均值i+1 -ΔTin 均值i ≥ΔTin 均值i -ΔTin 均值i-1 ≥T_cool_4℃, continuous trend change occurs, and DSH≥DSH_cool_2℃; - historical data trend analysis and judgment of single-machine operating parameters

[0068] ΔTin 均值i+1 -ΔTin 本机基准 ≥T_cool_5℃, the data has a certain amount of change, and DSH≥DSH_cool_2℃; -Comparison between the current operating parameters of the single machine and the benchmark operating parameters of the machine

[0069] ΔTin 均值 -ΔTin 多机均值 ≥T_cool_5℃, and DSH≥DSH_cool_2℃; -Comparison of single machine data and multi-machine mean parameters

[0070] If any of the following conditions are met, it is judged that the refrigerant leakage is in the medium stage:

[0071] ΔTin 均值i+1 -ΔTin本机基准 ≥T_cool_6℃, the data has a certain amount of chang...

Abstract

The invention provides an air conditioner running state detection method and system. According to the air conditioner running state detection method and system, potential or impending air conditioner faults can be found in time based on air conditioner running state parameters. The method comprises the steps that current running parameters of a local air conditioner are acquired; benchmark running parameters of the local air conditioner, average running parameters of the local air conditioner within one cycle, and average values of the average running parameters of multiple air conditioners which are divided to be on the same platform within one cycle are acquired; in combination with the current running parameters, the benchmark running parameters, the average running parameters and the average value parameters of the multiple air conditioners, the running state of the local air conditioner is judged based on a judging model; the running state of the local air conditioner is analyzed based on the judged running state. If the analyzed running state indicates that the air conditioner has the possibility or the trend of faults, after-sales service can be arranged in time before the faults occur, in this way, the experience of a customer for using the air conditioner is improved, and the quality of the after-sales service is also improved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, and in particular to a method and system for detecting the operating state of an air conditioner. Background technique [0002] After the air conditioner is installed in the customer's home, its after-sales service is based on the customer's report for air-conditioning failure. This after-sales service is based on the customer's active start and the after-sales service department passively executes it; but the customer is not professional enough and can only Feedback the fault phenomenon of the air conditioner operation, which makes it impossible for after-sales personnel to accurately locate the fault location and type. After-sales personnel need to go to the customer to check and determine the fault location and type, and then go to the customer for maintenance again. This kind of after-sales service steps are cumbersome and efficient. Low, reduce customer experience, but also reduce t...
