[0039] Air conditioning equipment with a fresh air mode can bring fresh air into the indoor environment, improve the indoor air quality, and avoid the problem of turbid indoor air after the air conditioning equipment has been cooling or heating for a long time. The activation of the fresh air mode will affect the indoor ambient temperature. Therefore, the fresh air function of the current air conditioning equipment is turned on by the user on demand, or automatically turned on 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 turned on 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.

[0040] The embodiments of the present application are further described below with reference to the accompanying drawings.

[0041] 1 , FIG1 is a control method for an air conditioning device provided by an embodiment of the present application, which is applied to an air conditioning device with a fresh air mode. The control method includes but is not limited to the following steps:

[0042] Step S100, running cooling mode or heating mode;

[0043] Step S200, obtaining the indoor ambient temperature, set temperature, operating power and target power of the air conditioning equipment;

[0044] Step S300: In response to the first condition and the second condition being met, the fresh air mode is operated; wherein,

[0045] The first condition is that the absolute value of the difference between the indoor ambient temperature and the set temperature is less than a preset first temperature value;

[0046] 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.

[0047] Air conditioning equipment, or air conditioning systems, including air conditioners, exhaust equipment, and humidifiers, regulate the indoor air environment and improve user comfort. Air conditioning equipment with a fresh air mode draws fresh air from outside into the room, maintaining air flow and adjusting the proportion of gases like carbon dioxide in the air. For ease of explanation, the following uses an air conditioner as an example.

[0048] When the air conditioner is operating in cooling 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 operates in 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 air conditioner's compressor reaches the temperature and shuts down, and the air conditioner operates in a low-power state. At this time, the indoor fan speed is reduced, reducing the amount of cooling or heating delivered to the room. The fluidity of the indoor air environment decreases, and the user needs to manually turn on the air conditioner's fresh air mode or wait for the air conditioner to automatically turn on fresh air mode when specific conditions are met, which obviously results in a poor user experience.

[0049] In the embodiment of the present application, when the air conditioner is operating in cooling mode or heating mode, the difference between the indoor ambient temperature and the set temperature and the operating power of the air conditioner over a period of time are determined to determine whether to automatically turn on the fresh air mode (the fresh air mode can be turned on separately, the air conditioner can run the fresh air mode while running in cooling mode or heating mode, or the air conditioner can only be in fresh air mode, cooling mode, and heating mode at the same time). Specifically, the air conditioner collects the indoor ambient temperature during operation and determines whether the absolute value of the difference between the indoor ambient temperature and the set temperature is less than a 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 shutting down. At this time, the operating power of the air conditioner within a preset first time period is monitored. In the state of reaching the temperature and shutting down, the operating power of the air conditioner is significantly reduced. Therefore, the difference between the operating power of the air conditioner within the preset first time period and the target power is determined. 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 be deteriorating. Therefore, the fresh air mode can be activated to supply fresh air to the room. The target power is the typical power value when the air conditioner enters a low-power operating state. This typical power value represents the stable low-power operating power of the air conditioner in cooling or heating mode when the compressor reaches temperature and stops. For example, a typical power value represents the power value fluctuating around a certain value for a period of time after the compressor reaches temperature and stops. This power value can be used as the typical power value. Another example is the average power value of the operating power of each sample over a period of time after the compressor reaches temperature and stops. This average power value can be used as the typical power value.

[0050] 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 at present. In the second condition, the difference between the operating power and the target power is determined. It can be further determined that if the operating frequency is lower than the target power for a period of time that lasts for the preset first duration, the fresh air mode is operated.

[0051] 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 when it is in a low power consumption operating state.

[0052] 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 it reaches the temperature), 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 it is required to calculate the target power through 5 stable powers, then each time the air conditioner is started and enters the low-power operation state, the internal counter is +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. The target power calculation can be to find the average of the N stable powers, or to set a weight for each stable power, and to obtain the target power based on the weighted calculation.

[0053] After calculating the target power, the air conditioner does not need to record the stable power during subsequent startup. That is, after the number of recorded stable power reaches N, the stable power will no longer be recorded after the air conditioning equipment is turned on. With this method, after the user runs a newly purchased air conditioner, the air conditioner will automatically determine the target power based on the previous low-power operation, and use it to enter the fresh air mode control during subsequent use, realizing intelligent learning and intelligent control. Of course, the stable power can still be recorded for each startup after the number of recorded stable power 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.

[0054] It is understood that the stable power of the air conditioner can be determined in a variety of ways. For example, referring to FIG2 , the stable power is determined by the following steps:

[0055] 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, obtaining the operating power of the air conditioning device;

[0056] Step S420: When the operating power remains stable within the preset second time period, the operating power is determined to be stable power.

[0057] When the air conditioner is started in cooling mode or heating mode, or enters cooling mode or heating mode after startup, the difference between the indoor ambient temperature and the set temperature is determined. If the absolute value of the difference is less than a preset second temperature value, indicating that the indoor ambient temperature is close to the set temperature and the air conditioner may have entered a low-power operation state, the operating power of the air conditioner at that time is recorded. If the operating power remains stable for a preset second time period, the air conditioner is considered to be operating stably in the low-power state, and the stable power is determined based on the recorded operating power.

[0058] 3 , in step S420, when the operating power remains stable within the preset second time period, determining that the operating power is stable power includes:

[0059] Step S421, determining a reference value based on the operating power recorded within a preset second time period;

[0060] 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.

[0061] After recording the operating power, a reference value can be determined based on the recorded operating power. The reference value can be the average operating power or an average value obtained by other mean calculation methods. The operating power recorded during the preset second time period is compared with the reference value. If the error between each operating power and the reference value is within a 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.

[0062] In some embodiments, the second condition further includes:

[0063] 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 longer than the preset time.

[0064] and / or,

[0065] The absolute value of the difference between the set temperature and the outdoor ambient temperature is less than the preset third temperature value.

[0066] 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 during which the operating power is lower than the target power is recorded. If the operating time is longer than the preset time, for example, the operating time is longer 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 activated to introduce air with an outdoor temperature not significantly higher than the set temperature into the room, speeding up indoor air flow without significantly increasing the indoor ambient temperature, thereby improving the user experience.

[0067] After the fresh air mode is turned on, the outside air will enter the room, which will inevitably affect the indoor ambient temperature. If the indoor ambient temperature is too high, it is necessary to return to the cooling mode. If the indoor ambient temperature is too low, it is necessary to return to the heating mode. Specifically, as shown in Figure 4, after the fresh air mode is running, the control method also includes:

[0068] 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.

[0069] 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 step S500 turns off the fresh air mode, 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 activated, after step S500 turns off the fresh air mode, the air conditioner resumes the operating mode before the fresh air mode is activated, that is, resumes the cooling mode or the heating mode. 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 significantly from the set temperature, the fresh air mode needs to be stopped and restored according to the recorded operating mode.

[0070] 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.

[0071] The control method of the air conditioning equipment of the present application is described in detail below through a specific example.

[0072] The control method includes intelligent learning process and intelligent control process.

[0073] Intelligent learning process:

[0074] 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;

[0075] Step 1.2: Each time you turn on the air conditioner, start step 1.1 until you have recorded five low-power operation power values ​​Pi, which are recorded as P1, P2, P3, P4, and P5 respectively. Calculate the average low-power operation power using the following formula and set it as Pt

[0076] Pt=(P1+P2+P3+P4+P5) / 5

[0077] Step 1.3, after completing the Pt setting, the air conditioner will no longer enter the intelligent learning mode each time it is turned on, and the intelligent control process will be activated.

[0078] Intelligent control process:

[0079] Step 2.1, in cooling mode or heating mode, when it is determined 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 duration t during which the current operating power P is less than Pt;

[0080] Step 2.2: When t is greater than 5 minutes, start identifying 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.

[0081] Step 2.3: In the fresh air exchange mode, if it is detected 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, the system automatically enters the user's initial setting mode to realize the heating / cooling function.

[0082] According to the control method of the embodiment of the present application, there are at least the following beneficial effects: when the air-conditioning equipment is operating in cooling mode or heating mode, when the indoor ambient temperature is basically stable near the set temperature, the operating power of the air-conditioning equipment is determined. If the absolute value of the difference between the operating power and the target power is less than the preset power value, it is considered that the air-conditioning equipment is stable in a low-power operating state. At this time, the air-conditioning equipment can be controlled to turn on the fresh air function to speed up the indoor air flow, thereby improving the user's comfort; since the target power represents the typical power value of the air-conditioning equipment in the low-power operating state in the cooling mode or the heating mode, based on the comparison between the current operating power and the target power, it can be accurately judged that the air-conditioning equipment is already in a low-power operating state and the indoor air flow rate 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.
