[0037] Air conditioning equipment with fresh air mode can bring fresh air into the indoor environment, improve indoor air quality, and avoid the problem of turbid indoor air after long-term cooling or heating of the air conditioning equipment. The activation of the fresh air mode will affect the indoor ambient temperature. Therefore, the fresh air function of the air conditioning equipment is currently activated by the user on demand, or automatically activated according to indoor air quality parameters (such as carbon dioxide concentration, VOC index, etc.). However, when the indoor ambient temperature is close to the set temperature, the cooling or heating power of the air conditioning equipment decreases, and the fan speed decreases, making the indoor air flow worse. If the fresh air mode is automatically activated after the air quality parameters deteriorate to a certain extent, the user experience will be poor and the user's fresh air needs cannot be met.

[0038] The embodiments of the present application are further described below in conjunction with the accompanying drawings.

[0039] Reference Figure 1 As shown, Figure 1A control method for an air conditioning device provided by an embodiment of the present application is applied to an air conditioning device with a fresh air mode. The control method includes but is not limited to the following steps:

[0040] Step S100, running in cooling mode or heating mode;

[0041] Step S200, obtaining the indoor environment temperature, the set temperature, the operating power and the target power of the air conditioning equipment;

[0042] Step S300, in response to the first condition and the second condition being met, running the fresh air mode; wherein,

[0043] The first condition is that the absolute value of the difference between the indoor ambient temperature and the set temperature is less than the preset first temperature value;

[0044] The second condition is that the absolute value of the difference between the operating power and the target power is less than a preset power value; the target power represents a typical power value of the air conditioning equipment in a low-power operating state in a cooling mode or a heating mode.

[0045] Air conditioning equipment, or air conditioning systems, including air conditioners, exhaust equipment, humidification equipment, etc., can adjust the indoor air environment and improve the user's comfort. Air conditioning equipment with fresh air mode can introduce fresh air from the outside into the room, maintain the fluidity of the indoor air and adjust the proportion of gases such as carbon dioxide in the indoor air. For the sake of convenience, the following is an example of an air conditioning equipment being an air conditioner.

[0046] When the air conditioner is running in cooling mode or heating mode, the compressor runs and drives the refrigerant to flow between the indoor heat exchanger and the outdoor heat exchanger, cooling or heating the indoor air through heat exchange. The user can set the cooling or heating temperature of the air conditioner, that is, the set temperature, and the air conditioner automatically runs the cooling mode or heating mode according to the set temperature and the indoor ambient temperature. When the difference between the indoor ambient temperature and the set temperature is small, the compressor of the air conditioner reaches the temperature and stops, and the air conditioner runs in a low power consumption state. At this time, the speed of the indoor fan is reduced, reducing the amount of cold or heat delivered to the room. The fluidity of the indoor air environment decreases, and the user needs to manually turn on the fresh air mode of the air conditioner or wait for the air conditioner to meet specific conditions to automatically turn on the fresh air mode, which obviously causes a bad user experience.

[0047] In the embodiment of the present application, when the air conditioner is running in cooling mode or heating mode, by judging the size between the indoor ambient temperature and the set temperature and the operating power of the air conditioner within a period of time, it is determined whether to automatically turn on the fresh air mode (the fresh air mode can be turned on separately, the air conditioner runs the fresh air mode while running the cooling mode or heating mode, and the air conditioner can also only be in one of the fresh air mode, cooling mode and heating mode at the same time). Specifically, the air conditioner collects the indoor ambient temperature during operation, and judges whether the absolute value of the difference between the indoor ambient temperature and the set temperature is less than the preset first temperature value. If the absolute value of the difference between the indoor ambient temperature and the set temperature is less than the preset first temperature value, it is considered that the air conditioner may be in a state of reaching the temperature and stopping, and the operating power of the air conditioner within the preset first time length is monitored at this time. In the state of reaching the temperature and stopping, the operating power of the air conditioner is significantly reduced, so the difference between the operating power of the air conditioner within the preset first time length and the target power is judged. If the absolute value of the difference is less than the preset power value, it is considered that the air conditioner is currently in a low-power operation state, and the fluidity of the indoor air may deteriorate, so the fresh air mode can be started to deliver fresh air to the room. The target power is the typical power value when the air conditioner enters the low-power operation state. This typical power value represents the stable low-power operation power of the air conditioner in the cooling mode or heating mode when the compressor stops at the temperature. For example, the typical power value indicates that the compressor fluctuates around a certain power value for a period of time after the compressor stops at the temperature. This power value can be used as the typical power value; for another example, the typical power value indicates the average power value of the operating power of each sample for a period of time after the compressor stops at the temperature. This average power value can be used as the typical power value.

[0048] In the first condition, the first duration can be set according to actual needs, for example, it can be set to 5 minutes. The preset first temperature value and the preset power value can also be set according to actual needs, for example, the preset first temperature value is set to 1.5 degrees Celsius, and the preset power value is set to 0 or 10W, etc., which are not limited now. In the second condition, the difference between the operating power and the target power is determined. It can be further determined that the operating frequency is lower than the target power for a preset first duration, and the fresh air mode is operated.

[0049] In some embodiments, the target power is determined by a plurality of stable powers, where the stable power is the operating power of the air conditioning device in a low power consumption operating state.

[0050] This embodiment proposes a method for determining the target power. After each startup of the air conditioner, for example, after entering the low-power operation state from the cooling mode or the heating mode (i.e., the compressor stops when the temperature reaches the limit), the stable power in the low-power operation state during the startup is recorded. After multiple startups and recording of multiple stable powers, the target power is determined based on the multiple stable powers. For example, if the target power is required to be calculated using 5 stable powers, then each time the air conditioner is started and enters the low-power operation state, the internal counter is increased by 1, and the current stable power is stored. When the internal counter = 5, the target power is calculated based on the 5 stored stable powers. That is, when the number of recorded stable powers reaches N, the target power is determined based on the N stable powers, where N is a positive integer. Among them, the target power calculation can be to find the average value of the N stable powers, or a weight can be set for each stable power, and the target power can be obtained by weighted calculation based on the weight.

[0051] After the target power is calculated, the air conditioner does not need to record the stable power during the subsequent startup and operation. That is, after the number of recorded stable powers reaches N, the stable power will no longer be recorded after the air conditioning equipment is turned on. In this way, after the user runs the newly purchased air conditioner, the air conditioner will determine the target power by itself based on the previous low-power operation conditions, and use it to enter the fresh air mode control during subsequent use, realizing intelligent learning and intelligent control. Of course, the stable power of each startup can still be recorded after the number of recorded stable powers reaches N. Based on the continuously recorded stable power, the target power is more accurate and more in line with the user's daily usage habits.

[0052] It is understood that the stable power of the air conditioner can be determined in a variety of ways. Figure 2 As shown, the stable power is determined by the following steps:

[0053] Step S410, after the air conditioning device is turned on and enters the cooling mode or the heating mode, when the absolute value of the difference between the indoor ambient temperature and the set temperature is less than a preset second temperature value, the operating power of the air conditioning device is obtained;

[0054] Step S420: When the operating power remains stable within a preset second time period, the operating power is determined to be stable power.

[0055] When the air conditioner is started in cooling mode or heating mode, or enters cooling mode or heating mode after being started, the difference between the indoor ambient temperature and the set temperature is determined. If the absolute value of the difference is less than the preset second temperature value, it indicates that the indoor ambient temperature is close to the set temperature, and the air conditioner may enter a low-power operation state, and the operating power of the air conditioner at this time is recorded. If the operating power remains stable within the preset second time period, it is considered that the air conditioner is stably operating in a low-power state, and the stable power is determined based on the recorded operating power.

[0056] Among them, refer to Figure 3 As shown, in the above step S420, when the operating power remains stable within the preset second time period, determining that the operating power is stable power includes:

[0057] Step S421, determining a reference value according to the operating power recorded within a preset second time period;

[0058] Step S422: When the error between the operating power recorded within the preset second time period and the reference value is within a preset error range, the reference value is used as the stable power.

[0059] After recording the operating power, a reference value can be determined based on the recorded operating power. The reference value can be the average value of the operating power or the average value obtained by other mean calculation methods. The operating power recorded within the preset second time period is compared with the reference value. If the error between each operating power and the reference value is within the preset error range, the reference value can be used as the stable power. The error calculation can be a simple numerical difference or variance, etc., which is not limited here.

[0060] In some embodiments, the second condition further includes:

[0061] The absolute value of the difference between the operating power and the target power is less than the preset power value, and the operating time is greater than the preset time.

[0062] and / or,

[0063] The absolute value of the difference between the set temperature and the outdoor ambient temperature is smaller than the preset third temperature value.

[0064] When the absolute value of the difference between the operating power and the target power is less than the preset power value, the total operating time when the operating power is lower than the target power is recorded. If the operating time is greater than the preset time, for example, the operating time is greater than 5 minutes, the difference between the set temperature and the outdoor ambient temperature is determined. If the difference between the set temperature and the outdoor ambient temperature is not large, the fresh air mode is turned on to introduce air with an outdoor temperature not significantly higher than the set temperature into the room, speeding up the indoor air flow without significantly increasing the indoor ambient temperature, thereby improving the user experience.

[0065] After turning on the fresh air mode, the outside air entering the room will inevitably affect the indoor ambient temperature. If the indoor ambient temperature is too high, you need to return to the cooling mode. If the indoor ambient temperature is too low, you need to return to the heating mode.

[0066] Specifically, refer to Figure 4 As shown, after running the fresh air mode, the control method further includes:

[0067] Step S500, in response to the absolute value of the difference between the indoor ambient temperature and the set temperature being greater than a preset first temperature value, turning off the fresh air mode.

[0068] If the absolute value of the difference between the indoor ambient temperature and the set temperature is greater than the preset first temperature value, the fresh air mode is turned off. If the activation of the fresh air mode is independent of the activation of the cooling mode or the heating mode and can be activated at the same time, the outdoor air introduced by the fresh air mode can be mixed with the air after heat exchange in the indoor heat exchanger and then supplied to the room. In this case, after the fresh air mode is turned off in step S500, the air conditioner continues to operate in the current cooling mode or heating mode. If only one of the fresh air mode and the cooling mode or the heating mode can be selected to be activated, after the fresh air mode is turned off in step S500, the air conditioner resumes the operating mode before the fresh air mode is turned on, that is, the cooling mode or the heating mode is resumed. Therefore, it can be seen that before entering the fresh air mode, the air conditioner needs to record the current operating mode, such as the cooling mode or the heating mode. When the indoor ambient temperature deviates greatly from the set temperature, the fresh air mode needs to be stopped and restored according to the recorded operating mode.

[0069] Through the above steps, the problem of poor indoor air flow caused by the air conditioner running for a long time in cooling mode or heating mode is solved. Based on the comparison between the current operating power and the target power, it can be accurately judged that the air conditioning equipment is in a low-power operating state and the flow rate of the indoor air is reduced, and then the fresh air mode is started. Compared with the existing technology that requires the user to manually turn on the fresh air function or continuously turn on the fresh air function, this solution can better improve the user's comfort.

[0070] The control method of the air conditioning equipment of the present application is described in detail below through a specific example.

[0071] The control method includes intelligent learning process and intelligent control process.

[0072] Intelligent learning process:

[0073] Step 1.1, in cooling mode or heating mode, when the absolute value of the difference between the set temperature T and the actual indoor ambient temperature T1 is less than or equal to 1.5 degrees Celsius, the actual low-power operation power of the air conditioner at this time is recorded as Pi, where i is a positive integer;

[0074] Step 1.2: Each time the air conditioner is turned on, start step 1.1 until the low-power operation power Pi is recorded for 5 times, which are recorded as P1, P2, P3, P4, and P5 respectively. The average low-power operation power is calculated by the following formula and set as Pt

[0075] Pt=(P1+P2+P3+P4+P5) / 5

[0076] Step 1.3, after completing the Pt setting, the air conditioner will no longer enter the intelligent learning mode and activate the intelligent control process each time it is turned on.

[0077] Intelligent control process:

[0078] Step 2.1, in cooling mode or heating mode, when it is identified that the current operating power P of the air conditioner is less than Pt, and the absolute value of the difference between the set temperature T and the actual indoor ambient temperature T1 is less than or equal to 1.5 degrees Celsius, start recording the time t during which the current operating power P is less than Pt;

[0079] Step 2.2, when t is greater than 5 minutes, start to identify the set temperature and the outdoor ambient temperature. When the absolute value of the difference between the set temperature T and the outdoor ambient temperature T2 is less than 3 degrees Celsius, start the fresh air mode;

[0080] Step 2.3, in the fresh air exchange mode, if it is recognized that the actual indoor ambient temperature T1 deviates from the set temperature T, that is, when the absolute value of the difference between the set temperature T and the actual indoor ambient temperature T1 is greater than 1.5 degrees Celsius, it automatically enters the user's initial setting mode to realize the heating / cooling function.
