[0041] In order to make the above objectives, features and advantages of the present application more apparent, further specific embodiments of the present application will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0042] Referring to Figures 1-3 , Figure 1 is a step flow chart of an exhaust temperature sensing bag detection method embodiment of the present application, which can specifically include the following steps:

[0043] acquiring a current exhaust temperature value T1;

[0044] adjusting the electronic expansion valve by a first number of steps to obtain a first adjustment state Z1;

[0045] acquiring an exhaust temperature value T2 under the first adjustment state Z1;

[0046] if a difference between the exhaust temperature value T1 and the exhaust temperature value T2 is not less than a preset temperature difference Ty1, adjusting the electronic expansion valve by a second number of steps to obtain a second adjustment state Z2;

[0047] acquiring an exhaust temperature value T3 under the second adjustment state Z2;

[0048] acquiring a preset exhaust temperature value T4 under the second adjustment state Z2;

[0049] When the difference between the exhaust temperature value T3 and the preset exhaust temperature value T4 is not less than the preset temperature difference Ty2, it is determined that the exhaust temperature sensing bulb is abnormal. More specifically, by adjusting the opening of the electronic expansion valve, the temperature difference between the temperature value in different states and the corresponding preset temperature value can be obtained, and the running state of the exhaust temperature sensing bulb can be determined according to the temperature difference. It should be noted that the air conditioner can have two running conditions, i.e., a stable running condition and an unstable running condition. When the air conditioner is running unstably, the electronic expansion valve needs to be adjusted by a preset number of steps. In this embodiment, the electronic expansion valve is adjusted by a first number of steps, and at this time, the running state of the air conditioner can be detected, i.e., whether the air conditioner tends to run stably can be determined by the temperature difference in the first adjustment state Z1. When the difference between the exhaust temperature value T1 and the exhaust temperature value T2 is not less than the preset temperature difference Ty1, it indicates that the air conditioner tends to run stably, and at this time, the electronic expansion valve can be adjusted by a second number of steps. In the second adjustment state Z2, when the difference between the exhaust temperature value T3 and the preset exhaust temperature value T4 is not less than the preset temperature difference Ty2, it indicates that when the air conditioner runs stably, the exhaust temperature difference is still too large, and at this time, it is determined that the exhaust temperature sensing bulb is abnormal, and the user is reminded of the abnormal state of the exhaust temperature sensing bulb.

[0050] In the following, a detection method of an exhaust temperature sensing bulb in the present exemplary embodiment will be further described.

[0051] As an example, before the step of adjusting the electronic expansion valve by a first number of steps to obtain a first adjustment state Z1, the method further comprises:

[0052] obtaining a current target exhaust temperature value T0;

[0053] If the difference between the exhaust temperature value T1 and the target exhaust temperature value T0 is not greater than a preset temperature difference Ty0, a pressure judgment process is performed on the exhaust pressure value, and the state of the exhaust temperature sensing bulb is obtained through the pressure judgment process. More specifically, when the difference between the exhaust temperature value T1 and the target exhaust temperature value T0 is not greater than the preset temperature difference Ty0, it indicates that the air conditioner is in a stable running state at this time; and when the difference between the exhaust temperature value T1 and the target exhaust temperature value T0 is greater than the preset temperature difference Ty0, it indicates that the air conditioner is in an unstable running state at this time, and the exhaust temperature is still in an adjusting state, and the electronic expansion valve needs to be adjusted by a number of steps to achieve a stable running state of the air conditioner.

[0054] As an example, the pressure judgment process comprises:

[0055] obtaining a current exhaust pressure value P1 and a target exhaust pressure value P0;

[0056] If the difference between the exhaust pressure value P1 and the target exhaust pressure value P0 is not greater than a preset pressure difference value Py1, it is determined that the exhaust temperature sensing bag state is normal.

[0057] If the difference between the exhaust pressure value P1 and the target exhaust pressure value P0 is greater than a preset pressure difference value Py1, it is determined that the exhaust temperature sensing bag state is abnormal, and the user is reminded of the abnormal state of the current exhaust temperature sensing bag. More specifically, when the difference between the exhaust temperature value T1 and the target exhaust temperature value T0 is not greater than a preset temperature difference value Ty0, it means that the air conditioner is running stably at this time, and the state of the exhaust temperature sensing bag can be directly determined by the exhaust pressure value at this time. That is, the current exhaust pressure value P1 is obtained by the pressure sensor, and the target exhaust pressure value P0 is obtained under the stable running state of the air conditioner. When the difference between the exhaust pressure value P1 and the target exhaust pressure value P0 is not greater than a preset pressure difference value Py1, it means that the exhaust pressure value associated with the exhaust temperature is stable, and it is determined that the exhaust temperature sensing bag state is stable and normal. When the difference between the exhaust pressure value P1 and the target exhaust pressure value P0 is greater than a preset pressure difference value Py1, it means that the exhaust pressure value associated with the exhaust temperature is unstable, or there is a large error in the exhaust pressure, so that the exhaust temperature sensing bag state is determined to be abnormal, and the user is reminded of the abnormal state of the current exhaust temperature sensing bag through the panel.

[0058] As an example, after the step of obtaining the exhaust temperature value T2 in the first adjustment state Z1, it further includes:

[0059] If the difference between the exhaust temperature value T1 and the exhaust temperature value T2 is less than a preset temperature difference value Ty1, it is determined that the exhaust temperature sensing bag state is abnormal, and the user is reminded of the abnormal state of the current exhaust temperature sensing bag. More specifically, when the air conditioner is not running stably, if the difference between the exhaust temperature value T1 and the exhaust temperature value T2 is still less than a preset temperature difference value Ty1 in the first adjustment state Z1, it means that there is a problem between the exhaust temperature difference and the step number change of the electronic expansion valve, and the exhaust temperature is abnormal, so the user should be reminded of the abnormal state of the current exhaust temperature sensing bag.

[0060] As an example, in the step of obtaining the exhaust temperature value T3 in the second adjustment state Z2, it further includes:

[0061] A preset running time S1;

[0062] In the second adjustment state Z2, the air conditioner obtains the exhaust temperature value T3 after running for a preset running time S1. More specifically, since the first step number adjustment is performed on the electronic expansion valve, it is only used to determine whether the air conditioner tends to be stable. Therefore, in order to ensure that the air conditioner is completely in a stable state when the second step number adjustment is performed on the electronic expansion valve, a preset running time S1 can be set. When the difference between the exhaust temperature value T1 and the exhaust temperature value T2 is not less than the preset temperature difference Ty1, the air conditioner needs to run for a preset running time S1 again. After running for the preset running time S1, the air conditioner has already been stable, and the second step number adjustment can be performed on the electronic expansion valve.

[0063] As an example, after the preset exhaust temperature value T4 step in the second adjustment state Z2, the following steps are further included:

[0064] When the difference between the exhaust temperature value T3 and the preset exhaust temperature value T4 is less than a preset temperature difference Ty2, it is determined that the exhaust temperature sensing bag is normal. In other embodiments, after the air conditioner runs for the preset running time S1 step in the second adjustment state Z2, the exhaust temperature sensing bag can also be determined by pressure detection. More specifically, the current exhaust pressure value P2 and the target exhaust pressure value P3 are obtained.

[0065] When the difference between the exhaust pressure value P2 and the target exhaust pressure value P3 is not greater than a preset pressure difference Py2, it is determined that the exhaust temperature sensing bag is normal.

[0066] When the difference between the exhaust pressure value P2 and the target exhaust pressure value P3 is greater than the preset pressure difference Py2, it is determined that the exhaust temperature sensing bag is abnormal, and the user is reminded of the abnormal state of the current exhaust temperature sensing bag. That is, when the difference between the exhaust temperature value T1 and the exhaust temperature value T2 is not less than the preset temperature difference Ty1, it means that the air conditioner has tended to be stable. At this time, the state of the exhaust temperature sensing bag can also be determined by the current exhaust pressure value. When the difference between the exhaust pressure value P2 and the target exhaust pressure value P3 is not greater than the preset pressure difference Py2, it is determined that the exhaust temperature sensing bag is normal. Since the state is different when the pressure is determined, that is, the preset pressure difference Py2 is set based on the stable state of the air conditioner, and the preset pressure difference Py1 is set based on the completely stable state of the air conditioner, the preset pressure difference Py2 and the previous preset pressure difference Py1 are generally not the same. It should be noted that in the second adjustment state Z2, the air conditioner is also in a completely stable state after running for a preset running time S1. At this time, the preset pressure difference Py2 and the previous preset pressure difference Py1 can be the same.

[0067] As an example, the second step of adjusting the electronic expansion valve to obtain the second adjustment state Z2 also includes:

[0068] The preset step adjustment range D0 for the electronic expansion valve;

[0069] The electronic expansion valve is adjusted in steps according to the step adjustment range D0 to obtain the second adjustment state Z2. More specifically, when the step number of the electronic expansion valve is too large, if the opening of the electronic expansion valve is reduced according to the large step number, it will be difficult to detect the exhaust temperature; at the same time, if the opening of the electronic expansion valve is increased according to the large step number, it may cause the exhaust temperature to be abnormally high, exceeding the temperature that the compressor windings can withstand, and damaging the compressor. To prevent these two situations from occurring, it is necessary to set an adjustable range for the step number of the electronic expansion valve. It should be noted that the air conditioner exhaust temperature is regulated by the electronic expansion valve. The electronic expansion valve uses a pulse stepper motor to control the movement of the valve needle to change the flow area of ​​the valve orifice, thereby achieving the purpose of regulating the flow. When the flow area of ​​the valve orifice increases, more refrigerant flows through, and the exhaust temperature is lower; when the flow area of ​​the valve orifice decreases, less refrigerant flows through, and the exhaust temperature is higher. The pulse of the electronic expansion valve is 0 to 480 pulses, generally referred to as the step number or opening. The valve orifice has the smallest flow area and the smallest flow rate when there are 0 pulses, and the valve orifice has the largest flow area and the largest flow rate when there are 480 pulses.
