[0035] In order to make the purpose, technical solutions and advantages of this application clearer, the technical solutions in this application will be clearly and completely described below in conjunction with the drawings in this application. Obviously, the described embodiments are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0036] The terms "first", "second", etc. in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first", "second", etc. are generally of one type, and the number of objects is not limited. For example, the first object can be one or more. In addition, "and / or" in the specification and claims represents at least one of the connected objects, and the character " / " generally indicates that the objects associated with each other are in an "or" relationship.

[0037] The operating principle of the air conditioner involved in the embodiment of the present application is described in detail below:

[0038] like Figure 1 As shown in the figure, the compressor compresses the refrigerant (coolant) and transports it to the condenser through a pipeline. The high-temperature and high-pressure gaseous refrigerant releases heat in the condenser and becomes a medium-temperature and high-pressure liquid refrigerant. After that, the medium-temperature and high-pressure liquid refrigerant is depressurized by a capillary tube (throttling unit) and becomes a low-temperature and low-pressure liquid refrigerant. The low-temperature and low-pressure liquid refrigerant is transported to the evaporator to evaporate from liquid to gas, and absorbs a large amount of heat during the evaporation process. Finally, the low-temperature and low-pressure gaseous refrigerant in the evaporator is transported to the compressor to participate in the next cycle.

[0039] Based on the above working principle, the working principle of the air conditioner in different working modes includes:

[0040] 1. Refrigeration cycle or heating cycle: The air conditioner achieves air cooling or heating through the refrigeration cycle or heating cycle of the outdoor unit. In the refrigeration cycle, the outdoor unit compresses the refrigerant into a high-temperature and high-pressure gas through the compressor, and then releases heat through the condenser to turn the refrigerant into a high-temperature and high-pressure liquid. Then, the refrigerant is expanded into a low-temperature and low-pressure liquid through the expansion valve, absorbing the heat of the indoor air and making the indoor air cool. In the heating cycle, the outdoor unit releases the heat of the refrigerant into the room by working in reverse, thereby achieving heating. 2. Indoor unit air supply and return: The air conditioner sends hot and cold air into the duct system through the indoor unit, and then transports it to different rooms or areas through the duct system. The indoor unit is usually equipped with a fan and a heat exchanger, which can send the hot and cold air transmitted from the outdoor unit into the duct system through the fan, and then transport it to different rooms or areas through the duct. The indoor unit will also absorb indoor air and exchange heat with the refrigerant, thereby achieving indoor air cooling or heating. 3. Duct system: The air conditioner transports hot and cold air to different rooms or areas through the duct system. The air duct system generally includes supply and return air channels. The supply air channel sends hot and cold air from the indoor unit to different rooms or areas, and the return air channel sends the air in the room back to the indoor unit through the return air outlet for further processing. 4. Temperature and wind speed control: The air conditioner is usually equipped with a temperature sensor and a wind speed controller. It can control the temperature and wind speed of different rooms or areas by controlling the operation of the outdoor and indoor units according to the temperature and wind speed requirements set by the user. Generally speaking, the air conditioner can achieve independent temperature control in different rooms or areas to provide a comfortable indoor environment.

[0041] In response to the technical problem in the related art that the energy consumption of turning on the fresh air function when the air conditioner is in cooling or heating mode is too high, the embodiment of the present application proposes that a suitable time can be selected to turn on the fresh air function of the air conditioner, which can not only reduce the energy consumption of the air conditioner, but also exchange indoor and outdoor air to improve indoor air quality.

[0042] The following is a detailed description of the fresh air control method for an air conditioner provided in the embodiment of the present application through specific embodiments and their application scenarios in conjunction with the accompanying drawings.

[0043] like Figure 2 As shown, an embodiment of the present application provides a fresh air control method for an air conditioner, the method may include the following steps 201 to 203:

[0044] Step 201: When the air conditioner is running, obtain temperature parameter information of the current environment and the working mode of the air conditioner.

[0045] The temperature parameter information includes: indoor ambient temperature, outdoor ambient temperature and set temperature of the air conditioner; the working modes of the air conditioner include: cooling mode, heating mode and air supply mode.

[0046] For example, before determining whether the fresh air function of the air conditioner can be turned on, it is first necessary to determine the working mode of the air conditioner, the indoor ambient temperature, the outdoor ambient temperature of the current environment, and the set temperature of the air conditioner. Afterwards, it is determined whether the fresh air function of the air conditioner can be turned on based on the working mode of the air conditioner and the indoor ambient temperature, the outdoor ambient temperature, and the set temperature of the air conditioner.

[0047] Step 202: Determine whether the fresh air function needs to be turned on based on the temperature parameter information and the working mode of the air conditioner.

[0048] For example, since the air conditioner operates differently and has different purposes of use (including heating, cooling, etc.) in different working modes, it is necessary to determine whether the fresh air function needs to be turned on in combination with the working mode of the air conditioner.

[0049] Specifically, the above step 202 may include the following steps 202a:

[0050] Step 202a: when the indoor ambient temperature does not reach the set temperature, compare the outdoor ambient temperature and the indoor ambient temperature based on the working mode of the air conditioner, and determine whether the fresh air function needs to be turned on according to the comparison result.

[0051] It is understandable that when the working mode of the air conditioner is cooling mode or heating mode, and the indoor ambient temperature has reached the set temperature of the air conditioner, if the fresh air function of the air conditioner is turned on at this time, it may cause a significant change in the indoor ambient temperature, causing the compressor to restart, thereby increasing the energy consumption of the air conditioner. Based on this, the fresh air control method for the air conditioner provided in the embodiment of the present application first needs to determine whether the indoor ambient temperature has reached the set temperature of the air conditioner before determining whether the fresh air function needs to be turned on. If not, it can be further determined whether the fresh air function needs to be turned on.

[0052] It should be noted that in the embodiment of the present application, the judgment criterion for turning on the fresh air function is: whether it will increase the energy consumption of the air conditioner. If so, the fresh air function will not be actively turned on. If not, turning on the fresh air function can not only improve the indoor air quality, but also reduce the energy consumption of the air conditioner to a certain extent.

[0053] Specifically, in the case where the current working mode of the air conditioner is the cooling mode, the above step 202a may include the following steps 202a1 and 202a2:

[0054] Step 202a1: when the working mode of the air conditioner is the cooling mode, determine whether the outdoor ambient temperature is lower than the indoor ambient temperature.

[0055] Step 202a2: When the outdoor ambient temperature is lower than the indoor ambient temperature, determine to turn on the fresh air function.

[0056] For example, when the air conditioner is in cooling mode, if the outdoor ambient temperature is lower than the indoor ambient temperature, the fresh air function of the air conditioner can be turned on to introduce outdoor air into the room to lower the indoor ambient temperature. In this way, the indoor air quality can be improved and the energy consumption of the air conditioner can be reduced.

[0057] It is understandable that the air conditioner is usually turned on in command mode in the hot summer to reduce the indoor ambient temperature, but at night the outdoor air is cooler, even lower than the indoor ambient temperature. At this time, the fresh air function of the air conditioner can be turned on. After turning on the fresh air function of the air conditioner, it can not only quickly reduce the indoor ambient temperature and indoor air quality, but also greatly reduce the energy consumption of the air conditioner.

[0058] Specifically, in the case where the current working mode of the air conditioner is the heating mode, the above step 202a may further include the following steps 202a3 and 202a4:

[0059] Step 202a3: When the working mode of the air conditioner is the heating mode, determine whether the outdoor ambient temperature is greater than the indoor ambient temperature.

[0060] Step 202a4: When the outdoor ambient temperature is greater than the indoor ambient temperature, determine to turn on the fresh air function.

[0061] For example, when the air conditioner is in heating mode, if the outdoor ambient temperature is greater than the indoor ambient temperature, the fresh air function of the air conditioner can be turned on to introduce outdoor air into the room to increase the indoor ambient temperature. In this way, the indoor air quality can be improved and the energy consumption of the air conditioner can be reduced.

[0062] It is understandable that the air conditioner usually starts the command mode in cold weather to increase the indoor ambient temperature, but when the sunlight intensity is high at noon, the outdoor air is relatively warm, even higher than the indoor ambient temperature. At this time, the fresh air function of the air conditioner can be turned on. After turning on the fresh air function of the air conditioner, not only can the indoor ambient temperature and indoor air quality be quickly increased, but also the energy consumption of the air conditioner can be greatly reduced.

[0063] Specifically, in the case where the current working mode of the air conditioner is the air supply mode, the above step 202a may further include the following steps 202a5 and 202a6:

[0064] Step 202a5: When the working mode of the air conditioner is the air supply mode, calculate a first temperature difference between the outdoor ambient temperature and the indoor ambient temperature.

[0065] Step 202a6: When the first temperature difference is less than or equal to a preset temperature difference threshold, determine to turn on the fresh air function.

[0066] For example, when the air conditioner is in air supply mode, if the difference between the outdoor ambient temperature and the indoor ambient temperature is small, the fresh air function of the air conditioner can be turned on to introduce outdoor air into the room to increase the indoor ambient temperature.

[0067] Step 203: When it is determined that the fresh air function needs to be turned on, the fresh air function is turned on, and based on the temperature parameter information and the working mode of the air conditioner, the operating parameters of the air conditioner are adjusted.

[0068] The adjustment of the operating parameters of the air conditioner is used to ensure that the operating effect of the air conditioner remains consistent with that before the adjustment.

[0069] For example, after determining to turn on the fresh air function of the air conditioner, in order to ensure that the operating effect of the air conditioner remains consistent with before the operating parameters are adjusted, the operating parameters of the air conditioner also need to be adjusted to avoid rapid changes in the indoor ambient temperature, while also reducing the energy consumption of the air conditioner.

[0070] Specifically, the above step 203 may include the following steps 203a1 to 203a3:

[0071] Step 203a1, calculating a second temperature difference between the outdoor ambient temperature and the indoor ambient temperature.

[0072] Step 203a2: determine a first additional adjustment ratio based on the second temperature difference, and determine the sum of the basic adjustment ratio and the first additional adjustment ratio as the first target adjustment ratio of the air conditioner operating parameter.

[0073] Step 203a3: Adjust the operating parameters of the air conditioner based on the first target adjustment ratio.

[0074] The first additional adjustment ratio is positively correlated with the second temperature difference; and the first target adjustment ratio is used to reduce various operating parameters of the air conditioner.

[0075] Exemplarily, in an embodiment of the present application, after it is determined to turn on the fresh air function, an additional adjustment ratio can be determined based on the basic adjustment ratio and the difference between the outdoor ambient temperature and the indoor ambient temperature, and then the basic adjustment ratio is added to the additional adjustment ratio to obtain the first target adjustment ratio.

[0076] It is understandable that after turning on the fresh air function, the operating parameters of the air conditioner can be appropriately reduced to reduce the energy consumption of the air conditioner. Specifically, the first target adjustment ratio can change with the change of the indoor and outdoor ambient temperature difference, that is, when the indoor and outdoor ambient temperature difference decreases, the low target adjustment ratio will also decrease.

[0077] In a possible implementation, after the fresh air function of the air conditioner is turned on, if the indoor ambient temperature is equal to the outdoor ambient temperature, the fresh air function of the air conditioner needs to be turned off to avoid increasing the energy consumption of the air conditioner.

[0078] Specifically, after the above steps 202a2 and 202a4, the fresh air control method for an air conditioner provided in the embodiment of the present application may further include the following step 204:

[0079] Step 204: after the air conditioner turns on the fresh air function, if the indoor ambient temperature of the current environment is equal to the outdoor ambient temperature of the current environment, turn off the fresh air function.

[0080] Specifically, after the above step 202c2, the fresh air control method for the air conditioner provided in the embodiment of the present application may further include the following step 205:

[0081] Step 205: After the air conditioner turns on the fresh air function, if the difference between the current indoor ambient temperature and the current outdoor ambient temperature is greater than the preset temperature difference threshold, turn off the fresh air function.

[0082] For example, in order to fully purify the indoor air, when it is determined that the fresh air function needs to be turned off, a delayed shutdown can be set, that is, when the shutdown conditions are met, the fresh air function of the air conditioner can be turned off after a preset time.

[0083] For example, Figure 3 As shown, it is a flow chart of the fresh air control method for the air conditioner provided by the embodiment of the present application. After the air conditioner is running, it can be determined whether the fresh air function of the air conditioner can be turned on in combination with the working mode of the air conditioner and the temperature parameter information of the current environment. If the fresh air function can be turned on, the operating parameters of the air conditioner are adjusted to reduce the energy consumption of the air conditioner.

[0084] Optionally, in an embodiment of the present application, if the user forcibly turns on the fresh air function of the air conditioner through manual control without satisfying the requirements for turning on the fresh air function, the operating parameters of the air conditioner need to be adjusted in order to ensure the consistency of the operating effect of the air conditioner.

[0085] Exemplarily, after the above step 202, the fresh air control method for an air conditioner provided in the embodiment of the present application may further include the following steps 206 to 208:

[0086] Step 206: When it is determined that the fresh air function is not turned on, if a fresh air function turn-on instruction for turning on the fresh air function is received, a third temperature difference between the outdoor ambient temperature and the indoor ambient temperature is calculated.

[0087] Step 207: Determine a second additional adjustment ratio based on the third temperature difference, and determine the sum of the basic adjustment ratio and the second additional adjustment ratio as a second target adjustment ratio of the air conditioner operating parameter.

[0088] Step 208: Adjust the operating parameters of the air conditioner based on the second target adjustment ratio.

[0089] The second additional adjustment ratio is positively correlated with the third temperature difference; and the second target adjustment ratio is used to improve various operating parameters of the air conditioner.

[0090] It is understandable that, if the user feels that the indoor air quality is poor and forcibly turns on the fresh air function after determining not to turn on the fresh air function, it is necessary to increase the compressor operating frequency of the air conditioner and / or the fan speed, etc. to improve the cooling or heating effect, so as to avoid a greater impact on the indoor ambient temperature after turning on the fresh air function.

[0091] Optionally, in an embodiment of the present application, when the air conditioner is just turned on, the operation of the air conditioner can be controlled in combination with the operating parameters of other air conditioners in the current area to realize the automation of the operation of the air conditioner, eliminating the step of manual setting by the user.

[0092] Exemplarily, before the above step 201, the fresh air control method for an air conditioner provided in the embodiment of the present application may further include the following steps 209 to 211:

[0093] Step 209: upon receiving a power-on instruction, obtaining user information of the air conditioner and user information of a first air conditioner in the area to which the air conditioner belongs and having the same performance parameters as the air conditioner.

[0094] It should be noted that, since air conditioners with different performance parameters have greatly different effects under the same operating parameters, the operating parameters of air conditioners with different performance parameters are of no reference significance and need to be excluded.

[0095] Step 210: Based on the user information of the air conditioner and the user information of the first air conditioner, a second air conditioner having the same user age group as the air conditioner is selected from the first air conditioner.

[0096] For example, in the implementation of this application, users can be divided according to age groups, for example, children under 6 years old, teenagers under 14 years old, young people under 30 years old, etc. The user's age can be obtained by the age set by the user when using the air conditioner, or by comprehensive judgment based on the user's height, gender, breathing rate, heart rate, body movements, and activity level detected by millimeter wave radar.

[0097] Step 211: taking the working mode of the third air conditioner in the running state in the second air conditioner as the current running mode of the air conditioner, and taking the average value of the running parameters of the third air conditioner as the current running parameters of the air conditioner.

[0098] Wherein, the first air conditioner includes a plurality of air conditioners; the operating parameters include at least one of the following: set temperature, compressor operating frequency, indoor unit fan speed, outdoor unit fan speed.

[0099] For example, after the working mode and operating parameters of the air conditioner are determined, the operation of the air conditioner can be controlled based on the working mode and operating parameters.
