When there are many people indoors, or the indoor airtight time is too long, the indoor carbon dioxide concentration increases. When the carbon dioxide concentration exceeds a certain level, the indoor personnel will feel dull and lose concentration.

The fresh air air conditioner in the existing technology can solve the problem of long indoor airtight time and increased carbon dioxide concentration, so that the indoor air can maintain a good quality.

[0061] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0062] like Figure 1 As shown, embodiment 1 of the present invention provides a control method for an air conditioner, which is used to control an air conditioner 10. The control method for the air conditioner includes: first starting the fresh air function to introduce fresh air into the room through the fresh air outlet 11; then obtaining the setting position of the fresh air outlet 11; and finally adjusting the operating frequency of the compressor of the air conditioner 10 according to the setting position of the fresh air outlet 11.

[0063] By using the control method of the air conditioner provided in this embodiment, it is determined that the fresh air function needs to be turned on, the position setting of the fresh air outlet 13 is obtained, and the operating frequency of the compressor is adjusted according to the setting position of the fresh air outlet 11. Such a setting can accurately control the operation of the compressor, so that the air conditioner 10 can better adjust the room temperature accurately, thereby facilitating better reaching the temperature set by the user and reducing the fluctuation of the room temperature caused by the introduction of fresh air. Therefore, the control method of the air conditioner provided in this embodiment can solve the problem of poor user comfort.

[0064] In this embodiment, the control method of the air conditioner further includes: obtaining the fresh air opening time and the fresh air outlet temperature, and determining the predetermined adjustment working frequency of the compressor according to the fresh air opening time and the fresh air outlet temperature. With such a setting, it is convenient to more accurately determine the influence of the fresh air on the indoor temperature fluctuation, so as to better adjust the compressor adaptively according to the state of the introduction of fresh air, so that the temperature can better reach the temperature set by the user, so as to effectively reduce the situation where the indoor temperature fluctuates greatly due to the introduction of fresh air.

[0065] Specifically, the method for determining the preset adjustment operating frequency of the compressor according to the fresh air opening time and the fresh air outlet temperature includes: obtaining the current operating frequency F of the compressor 当前 And the frequency change value △F, according to the current operating frequency F of the compressor 当前 And the frequency change value ΔF is used to calculate the predetermined adjustment working frequency. With such a setting, it is convenient to calculate the predetermined adjustment working frequency of the compressor more accurately, so as to accurately control the operating frequency of the compressor.

[0066] In this embodiment, the method for adjusting the operating frequency of the compressor of the air conditioner 10 according to the setting position of the fresh air outlet 11 includes: when the fresh air outlet 11 is the first fresh air outlet, the first adjustment mode is used to adjust the operating frequency of the compressor; when the fresh air outlet 11 is the second fresh air outlet, the second adjustment mode is used to adjust the operating frequency of the compressor. The first fresh air outlet is set at the side of the air inlet 12 of the air conditioner 10, and the second fresh air outlet is set at the side of the air outlet 13 of the air conditioner 10. With such a setting, corresponding adjustments can be made according to the position characteristics of different fresh air outlets 11, so as to ensure that no matter which fresh air outlet form is adopted, the influence of fresh air intake on indoor temperature fluctuations can be eliminated as much as possible.

[0067] Specifically, the first fresh air outlet corresponds to the upper air outlet, and the second fresh air outlet corresponds to the lower air outlet.

[0068] In this embodiment, the method of adjusting the working frequency of the compressor using the first adjustment mode includes: obtaining the fresh air opening time, comparing the fresh air opening time with the first predetermined time to obtain a first comparison result; obtaining the fresh air outlet temperature, comparing the fresh air outlet temperature with the first preset temperature to obtain a second comparison result; determining the predetermined adjustment working frequency of the compressor according to the first comparison result and the second comparison result, and adjusting according to the predetermined adjustment working frequency. With such a design, when the air outlet 13 is at the top, the problem of excessively high detection temperature caused by opening the fresh air for a long time can be avoided. At the same time, the distance between the fresh air outlet 13 and the air inlet 12 of the air conditioner 10 is relatively close, so that the temperature sensing package at the air inlet 12 of the air conditioner 10 will be more easily affected by the fresh air, thereby causing the detection temperature of the temperature sensing package at the air inlet 12 to be higher than the actual indoor temperature, and the method in this embodiment can reduce the influence of the temperature error, so that the compressor power can be controlled more accurately.

[0069] In this embodiment, the method for determining the predetermined adjustment operating frequency of the compressor according to the first comparison result and the second comparison result includes: obtaining the current operating frequency F of the compressor 当前 When the fresh air opening time is less than or equal to the first predetermined time and the fresh air outlet temperature is greater than the first preset temperature, the predetermined adjustment working frequency F is determined. 调节 For: F 调节 =F 当前 +γ1△F; when the fresh air opening time is less than or equal to the first predetermined time and the fresh air outlet temperature is less than or equal to the first preset temperature, determine the predetermined adjustment working frequency F 调节 For: F 调节 =F 当前 +γ2△F; when the fresh air opening time is greater than the first preset time and the fresh air outlet temperature is greater than the first preset temperature, determine the predetermined adjustment working frequency F 调节For: F 调节 =F 当前 +γ3△F; when the fresh air opening time is greater than the first preset time and the fresh air outlet temperature is less than or equal to the first preset temperature, determine the predetermined adjustment working frequency F 调节 For: F 调节 =F 当前 +γ4△F. Among them, F 当前 is the current operating frequency of the compressor, △F is the changing frequency value determined according to the environment, γ1, γ2, γ3 and γ4 are all parameters for adjusting the frequency, γ1≤γ2, γ1≤γ3, γ3≤γ4.

[0070] Because different fresh air startup times will have different effects on the ambient temperature, such a setting can make different adjustments to the frequency according to the length of the fresh air startup time and the changes in different fresh air outlet temperatures, so that the system can be controlled more accurately, so that the user's comfort when using the upper air outlet of the fresh air system is further improved.

[0071] In this embodiment, the method of adjusting the operating frequency of the compressor using the second adjustment mode includes: first obtaining the fresh air opening time, comparing the fresh air opening time with the second preset time to obtain a third comparison result; after obtaining the fresh air outlet temperature, comparing the fresh air outlet temperature with the second preset temperature to obtain a fourth comparison result, and then determining the predetermined adjustment operating frequency of the compressor according to the third comparison result and the fourth comparison result, and adjusting it according to the predetermined adjustment operating frequency. With such a setting, it is possible to make a difference in control from the adjustment mode in which the air outlet 13 is above, and the compressor power can be more accurately controlled when the air outlet 13 is below. Specifically, the second preset time can be the same value as the first preset time, which can be selected as 30min. The second preset temperature can be the same value as the first preset temperature, which can be selected as 30°C. The below here is not limited to directly below, but can also include the lower side.

[0072] In this embodiment, the method for determining the predetermined adjustment working frequency of the compressor according to the third comparison result and the fourth comparison result includes: when the fresh air opening time is less than or equal to the second predetermined time and the fresh air outlet temperature is greater than the second preset temperature, determining the working frequency F of the compressor 调节 For: F 调节 =δ1F 当前 When the fresh air opening time is less than or equal to the second predetermined time and the fresh air outlet temperature is less than or equal to the second preset temperature, determine the operating frequency F of the compressor 调节 For: F 调节 =δ2F 当前 When the fresh air opening time is greater than the second preset time and the fresh air outlet temperature is greater than the second preset temperature, determine the operating frequency F of the compressor 调节=F = F + δ3 ΔF; when the fresh air opening time is greater than the second predetermined time and the fresh air outlet temperature is less than or equal to the second preset temperature, the operating frequency F of the compressor is determined 调节 F = F + δ4 ΔF, where ΔF is the frequency value determined according to the environment, δ1, δ2, δ3 and δ4 are all parameters for adjusting the frequency, δ1 ≥ δ2, δ3 ≥ δ4.

[0073] By adopting such a setting method, when the air outlet 13 is at the bottom, the power calculation becomes more accurate, thereby improving the user's comfort experience in this working mode.

[0074] In this embodiment, the method for obtaining the fresh air outlet temperature includes: obtaining the outdoor environment temperature T when the air conditioner 10 is started w0 , get the outdoor ambient temperature T when the fresh air starts w1 , obtain the start time t1 of the air conditioner 10; according to the initial ambient temperature T w0 , Outdoor ambient temperature T w1 The fresh air outlet temperature is determined by the start time t1 of the air conditioner 10. With such a setting, the accuracy of obtaining the fresh air outlet temperature can be effectively improved, thereby making the compressor power control more accurate.

[0075] In this embodiment, according to the initial ambient temperature T w0 , Outdoor ambient temperature T w1 and the start time t1 of the fresh air air conditioner 10, the method for determining the fresh air outlet temperature comprises: comparing the start time t1 of the air conditioner 10 with the preset time to obtain a third comparison result; comparing the initial ambient temperature T w0 and outdoor ambient temperature T w1 The fresh air outlet temperature is determined according to the third comparison result and the fourth comparison result. This method can facilitate more convenient, quick and accurate determination of the fresh air outlet temperature.

[0076] In this embodiment, the method for determining the fresh air outlet temperature according to the third comparison result and the fourth comparison result includes: when the opening time t1 of the air conditioner 10 is less than or equal to the preset time, the initial ambient temperature T w0 is the fresh air outlet temperature; when the opening time t1 of the air conditioner 10 is greater than the preset time and the initial ambient temperature T w0 and outdoor ambient temperature T w1 When the difference is less than or equal to the preset temperature difference, the outdoor ambient temperature T w1 is the fresh air outlet temperature; when the start-up time t1 of the air conditioner 10 is greater than the preset time and the initial ambient temperature T w0 and outdoor ambient temperature T w1When the difference is greater than the preset temperature difference, the initial ambient temperature T w0 It is the fresh air outlet temperature.

[0077] With such a setting, the fresh air outlet temperature is determined based on the comparison results of time and temperature, which can avoid the situation where misjudgment leads to large errors in the outlet air temperature and improve the accuracy of the calculation.

[0078] Specifically, in this embodiment, the outlet air temperature after the fresh air is turned on is set to Tx. The determination method of Tx is specifically as follows: the initial ambient temperature when the air conditioner is turned on is recorded as T w0 The outer ring temperature at the time when the fresh air is turned on is recorded as T w1 , the opening time is t1.

[0079] When t1 is less than or equal to the preset value t 预设1 When t 预设1 =1h, Tx=T w0 ;

[0080] When t1 is greater than the preset value t 预设1 When T w1 -T w0 Is it ≤ preset value T W预设值 .

[0081] T W预设值 It changes with the running time, and the specific changes can be shown in the following table:

[0082] Start-up time <![CDATA[T W预设值 ]]> 1～4 4℃ More than 4 hours 6℃

[0083] When the judgment result is yes, Tx = T w1 ;

[0084] When the judgment result is no, Tx = T w0 .

[0085] This is because some air conditioner outdoor units are installed in poorly ventilated locations. After a long period of operation, the temperature around the air conditioner outdoor unit rises, even up to 60°C or above. If the outer ring temperature detected by the air conditioner outdoor unit is directly used to replace the outlet temperature of the fresh air, it is easy to misjudge that the outlet temperature is too high.

[0086] like Figure 2As shown, for the air conditioner with fresh air upper outlet, since the fresh air upper outlet is close to the air conditioner inlet 12, the temperature sensing package of the air conditioner inlet 12 (commonly known as the inner ring temperature sensing package) will be more easily affected by the fresh air. If the air conditioner adjusts the compressor frequency according to the conventional logic of the inner ring-set temperature difference at this time, it will be more likely to cause inaccurate room temperature control. For example, the fresh air outlet temperature is 35℃, and the indoor ambient temperature is 25℃. Due to the addition of fresh air, the ambient temperature is sampled as 30℃, but the temperature of the entire room does not actually rise to 30℃.

[0087] For the air conditioner with fresh air upward outlet, the control method is as follows:

[0088]

[0089] Among them, △F is the frequency value that should be changed due to the change in ambient temperature calculated based on the PID algorithm.

[0090] When the fresh air opening time is less than 30 minutes (this value is the preferred parameter).

[0091] When the fresh air outlet temperature is greater than 30°C, the compressor frequency is adjusted to F+γ1△F.

[0092] F is the current operating frequency F 当前 , △F is the frequency value that should be changed due to the change in ambient temperature calculated based on the PID algorithm.

[0093] γ1 is the frequency parameter that needs to be adjusted due to the addition of fresh air. γ1≤γ2; preferably γ1=0.7, γ2=0.8, because the higher the fresh air outlet temperature, the faster the actual ambient temperature rises. Therefore, the frequency needs to be adjusted downward. γ3≤γ4, preferably, γ3=0.8, γ4=0.9.

[0094] γ1≤γ3, because the longer the fresh air is turned on, the closer the ambient temperature is to the actual temperature. Therefore, the adjustment parameter is larger and the change is smaller when the fresh air is turned on for a long time.

[0095] like Figure 3 As shown, for the solution in which the fresh air outlet 11 is on the lower side, this air outlet form is opposite to that of the upper air outlet, which will cause the detection of the inner ring temperature to lag behind.

[0096] When it is actually detected that the ambient temperature does not change, the compressor frequency control method is shown in the following table.

[0097]

[0098] When the fresh air opening time is less than or equal to 30 minutes (this value is the preferred parameter). When the fresh air outlet temperature is greater than 30°C, F is the current working frequency F当前 , then the target frequency F 调节 =δ1F; δ1≥δ2, preferably δ2=1.1, δ1=1.2.

[0099] This is because after the fresh air is turned on, the fresh air is brought into the human activity area along the air flow of the air conditioner, and the temperature of the air inlet 12 located above changes slowly. Therefore, the frequency adjustment of the compressor is based on the current frequency.

[0100] When the fresh air opening time is greater than 30 minutes (this value is the preferred parameter), the indoor ambient temperature has changed due to a period of operation. Therefore, the change range is adjusted.

[0101] δ3≥δ4, preferably δ3=1.2, δ4=1.1.

[0102] In the second embodiment of the present invention, a non-volatile storage medium is provided, and the non-volatile storage medium includes a program, and the program adopts the air conditioner 10 control method in the first embodiment. By setting the non-volatile storage medium, it is convenient for the system to compare the current environmental state with the preset environmental state, so as to better control and adjust the air conditioner 10.

[0103] In the third embodiment of the present invention, an air conditioner 10 is also provided, and the air conditioner 10 includes: a fresh air start module, an acquisition module and an adjustment module. The fresh air start module is used to start the fresh air function to introduce fresh air into the room through the fresh air outlet 11; the acquisition module is used to obtain the setting position of the fresh air outlet 11; the adjustment module is used to adjust the operating frequency of the compressor of the air conditioner 10 according to the setting position of the fresh air outlet 11. By setting multiple modules and adjusting the air conditioner 10 in coordination, the air conditioner 10 can be made to operate more intelligently, and temperature fluctuations can be effectively avoided, thereby improving the user experience and user satisfaction.

[0104] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: when the air-conditioning fresh air is turned on, the air-conditioning fresh air outlet temperature is determined based on the time and the outer ring temperature. By judging the outlet form of the fresh air, based on different fresh air outlet forms, and according to the fresh air turning-on time and the fresh air outlet temperature, the compressor frequency control is adjusted. By adopting the technical solution in the present invention, the fresh air indoor unit can be turned on and off and operated intelligently, thereby solving the problem of room temperature fluctuations affecting user comfort and improving user comfort.
