Optionally, when the current operation mode of the air conditioner is the cooling mode, the first temperature difference is compared with the first value Δ T1Comparing if the first temperature difference is less than or equal to Δ T1Determining that the first auxiliary bypass needs to be opened; if the first temperature difference is greater than DeltaT1Then control maintains the first auxiliary bypass closed and control proceeds to the next recognition cycle. Wherein, one end of the first auxiliary bypass is connected with the inlet end of the outdoor heat exchanger in the cooling mode, the other end of the first auxiliary bypass is connected with the inlet end of the indoor heat exchanger in the cooling mode, and the first value can be set according to the actual situation, for example, can be set to-1 ℃.
For example, the current operation mode of the air conditioner is obtained as a cooling mode, T1And Ts24 ℃ and 26 ℃ respectively, and a.DELTA.T1At-1 ℃ whereby T is equal to or less than-1 and is 24-261-Ts≤△T1Indicating that the first auxiliary bypass needs to be opened.
Optionally, when the current operation mode of the air conditioner is the heating mode, the first temperature difference and the second value Δ T are compared2Comparing if the first temperature difference is greater than or equal to Δ T2If so, determining that a second auxiliary bypass needs to be opened; if the first temperature difference is less than or equal to Δ T2Then control maintains the second auxiliary bypass closed and control proceeds to the next recognition cycle. Wherein, one end of the second auxiliary bypass is connected with the inlet end of the indoor heat exchanger in the heating mode, the other end of the second auxiliary bypass is connected with the inlet end of the outdoor heat exchanger in the heating mode, and the second value can be set according to the actual situation, for example, can be set to 1 ℃.
For example, the current operation mode of the air conditioner is obtained as a heating mode, T1And Ts29 ℃ and 28 ℃ respectively, and a. DELTA.T21 ℃ to 29-28. gtoreq.1, i.e., T1-Ts≥△T2Indicating that the second auxiliary bypass needs to be opened.

Specifically, a first change trend is formed by utilizing the indoor temperature collected after the auxiliary bypass is opened for a preset time, the first change trend is compared with a second change trend before the auxiliary bypass is opened in a similarity manner, the trend of the first change trend is identified to be the same as the trend of the second change trend, the change trend of the indoor temperature is indicated to be unchanged, namely, the indoor temperature is not influenced after the auxiliary bypass is opened, when the indoor temperature continues to drop after the first auxiliary bypass is opened or the indoor temperature continues to rise after the second auxiliary bypass is opened, other factors possibly cause the problem of refrigeration or heating of the air conditioner, and the air conditioner is controlled to be shut down for safety. Otherwise, the current working state of the air conditioner is maintained. The preset duration can be set according to actual conditions.
The technical scheme in the embodiment of the application at least has the following technical effects or advantages:
because can open in this application and assist the bypass in order to change the refrigerating output or the heating capacity that flow into the heat exchanger after, detect indoor temperature, then when discerning to predetermine long back indoor temperature's trend of change still not taking place the change, can know that the air conditioner has now broken down, from this, can control the air conditioner and shut down, avoided the air conditioner still to operate the problem that the part that can cause damages and produce the potential safety hazard after breaking down.
Furthermore, after the corresponding auxiliary bypass is opened, the indoor temperature T of the air conditioner can be cyclically adjusted in real time1Set temperature T of air conditionersThe detection is carried out to identify whether the air conditioner needs to close the auxiliary bypass or not, so that the refrigerating capacity or the heating capacity of the air conditioner is improved, and the problem that the refrigerating or heating effect is influenced due to the fact that the indoor temperature is slowly adjusted when the auxiliary bypass is continuously maintained to be opened is avoided.
Fig. 4 is a flowchart illustrating a control method of an air conditioner according to another embodiment of the present disclosure. As shown in fig. 4, the method specifically includes the following steps:
s301, continuously detecting the indoor temperature.
And S302, judging whether the auxiliary bypass needs to be closed or not according to the indoor temperature and the set temperature which are continuously detected.
