Description

Technical Field

[0001] The present application relates to the technical field of smart home appliances, for example, to a control method and device for a fresh air device and a fresh air air conditioner. Background Art

[0002] Currently, fresh air devices and temperature control devices are used together to adjust both indoor temperature and air freshness to a user's comfort level. Furthermore, fresh air devices and temperature control devices can be combined into a fresh air air conditioner, allowing a single device to simultaneously adjust both indoor temperature and air freshness. During the temperature adjustment process, the indoor and outdoor temperatures often differ. As fresh air is introduced from outside, it interferes with the temperature adjustment process, making it difficult to stably adjust the indoor temperature to a user's comfort level.

[0003] In some existing fresh air air conditioning control processes, the indoor temperature and outdoor temperature are obtained, and the temperature difference between the indoor temperature and the outdoor temperature is calculated. Then, the speed of the indoor fan of the fresh air air conditioning is fine-tuned according to the temperature difference, and the relative amount of indoor air circulation and fresh air volume is changed. In this way, the cooling / heating power of the air conditioner is adjusted, and the temperature interference caused by the fresh air to the indoor temperature adjustment process is compensated, so as to improve the stability of the indoor temperature adjustment process.

[0004] In addition, for two offices with ventilation in an office scenario, or two rooms with ventilation in a home scenario, it is usually necessary to keep the temperature of the two offices or two rooms consistent so that users can have a better temperature experience when walking between the two rooms. Due to some normal work and life activities, such as meetings in office scenarios and cooking in home scenarios, there will be a large temperature difference between the two rooms. During the heating process, the heat in the higher temperature room will flow to the lower temperature room, and this heat flow has a promoting effect on the heating process of the lower temperature room; during the cooling process, the cold air in the lower temperature room will flow to the higher temperature room, and this heat flow has a promoting effect on the cooling process of the higher temperature room.

[0005] In some prior arts, based on the temperature difference between the two rooms, the outputs of the temperature adjustment devices of the two rooms may be compensated respectively, so that the temperatures of the two rooms can reach the set temperature relatively stably.

[0006] During the implementation of the embodiments of the present application, it was found that at least the following problems exist in the related art:

[0007] For two rooms with air flow, to adjust the temperature and air freshness of both rooms, the temperature control devices and fresh air devices in each room need to be controlled separately. When both the set temperature and the outdoor temperature are higher than the indoor temperature of both rooms, or when both the set temperature and the outdoor temperature are lower than the indoor temperature of both rooms, the outdoor temperature has a positive effect on the temperature change process in both rooms. In this case, if the heating / cooling power of the air conditioners in the two rooms is adjusted separately based on the temperature difference between the outdoor and indoor temperatures, during the heating process, the room with the lower indoor temperature has a larger temperature difference with the outdoor temperature, and the heating capacity needs to be reduced more to compensate for the impact of the fresh air on the indoor temperature. During the cooling process, the room with the higher indoor temperature has a smaller temperature difference with the outdoor temperature, to compensate for the impact of the fresh air on the indoor temperature. This compensation method results in the indoor temperature of the lower room taking longer to stabilize at the set temperature during the heating process, and the indoor temperature of the higher room taking longer to stabilize at the set temperature during the cooling process.

[0008] In addition, in the process of using the temperature difference between the two rooms to compensate for the indoor temperatures of the two rooms respectively, the heating power of the room with a lower temperature will be reduced during the heating process, and the cooling power of the room with a higher temperature will be reduced during the cooling process. This also results in a longer time required for the indoor temperature of the room with a lower temperature to stabilize at the set temperature during the heating process, and a longer time required for the indoor temperature of the room with a higher temperature to stabilize at the set temperature during the cooling process.

[0009] It should be noted that the information disclosed in the above background technology section is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to ordinary technicians in this field.

[0025] In some embodiments, a first fresh air device is provided in the first room, and there is air flow between the first room and the second room, and air flows from the second room into the first room.

[0032] In some embodiments, the control device of the fresh air device includes a processor and a memory storing program instructions, and the processor is configured to execute the control method of the fresh air device provided by the above embodiment when executing the program instructions.

[0033] In some embodiments, the fresh air air conditioner includes the control device of the fresh air device provided in the aforementioned embodiments.

[0034] The control method, device, and fresh air air conditioner of the fresh air device provided in the embodiments of the present application can achieve the following technical effects:

[0035] In a scenario where two rooms are heated up at the same time and the fresh air introduced into the two rooms can promote the heating process, the room with the lower temperature of the two rooms is the first room; in a scenario where two rooms are cooled down at the same time and the fresh air introduced into the two rooms can promote the cooling process, the room with the higher temperature is the first room; in the process where the temperatures of the two rooms change simultaneously, the following three situations may occur: in the first situation, the temperature difference between the indoor temperatures of the two rooms is large, and the current first temperature difference between the current first indoor temperature of the first room and the set temperature is large; in the second situation, the temperature difference between the indoor temperatures of the two rooms is small, and the current first temperature difference is large; in the third situation, the temperature difference between the indoor temperatures of the two rooms is small, and the current first temperature difference is small.

[0036] The target temperature promotion coefficient can represent the promoting effect of other factors besides the temperature regulating device in the first room on the temperature change process of the first room, such as the heat or cold carried by the fresh air introduced into the first room from the outside, and the heat or cold carried by the air flowing into the first room from the second room, which have a promoting effect on the temperature change process of the first room.

[0037] In the first and second cases mentioned above, the current first temperature difference is large. Since the target temperature promotion coefficient is positively correlated with the current first temperature difference, the target temperature promotion coefficient is large. Other factors except the temperature control device in the first room provide more heat to the first room when heating up and more cooling to the first room when cooling down, which is conducive to the current first indoor temperature of the first room changing to the set temperature relatively quickly; in the third case mentioned above, since the current first temperature difference is small, the target temperature promotion coefficient is small. Other factors except the temperature control device in the first room provide less heat to the first room when heating up and less cooling to the first room when cooling down, which causes less interference to the process of the temperature control device adjusting the first indoor temperature of the first room, shortens the time required for the first indoor temperature to stabilize at the set temperature, and makes the current first indoor temperature of the first room stabilize at the set temperature relatively quickly.

[0038] In summary, the control method of the fresh air device can enable the first indoor temperature of the first room to reach and stabilize at the set temperature more quickly.

[0050] In the embodiments of the present application, the character " / " indicates that the preceding and following objects are in an "or" relationship. For example, A / B means: A or B.

[0051] The term "and / or" describes an association between objects, indicating that three relationships can exist. For example, A and / or B means: A or B, or A and B.

[0052] Figure 1 This is a schematic diagram of the implementation environment of a control method for a fresh air device provided in an embodiment of the present application.

[0053] Combine Figure 1 As shown, room R1 and room R2 can be two rooms in a home setting or two rooms in an office setting. Air flow exists between room R1 and room R2. For example, room R1 does not have a door, or room R1 has a door but the door is open, and room R1 is connected to corridor C. Room R2 does not have a door, or room R2 has a door but the door is open, and room R2 is connected to corridor C. In this state, air flow exists between room R1 and room R2.

[0054] The first fresh air device F1 is installed in the first room R1, and the second fresh air device F2 is installed in the second room R1. One end of the first fresh air device F1 is connected to the first room R1 and the other end is connected to the outside, and is used to provide outdoor air to the first room R1. The second fresh air device F2 is connected to the second room R2 at one end and the other end is connected to the outside, and is used to provide outdoor air to the second room R2.

[0055] The first room R1 is equipped with a temperature control device, such as an air conditioner; the second room R2 is equipped with a temperature control device, such as an air conditioner. During the process of adjusting the indoor temperatures of the first and second rooms to a set temperature, when the indoor temperatures of the first and second rooms first reach the set temperature, the temperatures of the two rooms do not immediately stabilize at the set temperature, but fluctuate around the set temperature before eventually stabilizing at the set temperature.

[0056] The first room R1 is also provided with a first temperature sensor T1 and a first pressure sensor P1. The first temperature sensor T1 is used to detect the first indoor temperature in the first room R1, and the first pressure sensor P1 is used to detect the first pressure in the first room R1. The second room R2 is also provided with a second temperature sensor T2 and a second pressure sensor P2. The second temperature sensor T2 is used to detect the second indoor temperature in the second room R2, and the second pressure sensor P2 is used to detect the second pressure in the second room R2.

[0057] A third temperature sensor T3 and a third pressure sensor P3 are also provided outdoors; the third temperature sensor T3 is used to detect the outdoor temperature, and the third pressure sensor P3 is used to detect the outdoor pressure.

[0058] The situation where the current first indoor temperature is lower than the current second indoor temperature, the current first indoor temperature is lower than the current outdoor temperature, and the current second indoor temperature is lower than the set temperature, refers to the situation where the first room and the second room are heated up at the same time, and the outdoor temperature is conducive to heating up the first room and the second room. For example, at noon in late autumn and early winter, the indoor temperature of the room facing away from the sun is low, and the outdoor temperature is higher than the indoor temperature. The situation where the current first indoor temperature is higher than the current second indoor temperature, the current first indoor temperature is higher than the current outdoor temperature, and the current second indoor temperature is higher than the set temperature, refers to the situation where the first room and the second room are cooled down at the same time, and the outdoor temperature is conducive to cooling down the first room and the second room. For example, in rooms such as kitchens and bathrooms, after they are used, the indoor temperature is high, and the outdoor temperature is lower than the high indoor temperature. The above two situations are suitable for adopting the control method of the fresh air device provided in the embodiments of the present application.

[0059] In the embodiment of the present application, the target temperature promotion coefficient is used to represent the promoting effect of other factors on the temperature change process of the first room, in addition to the temperature regulating device of the first room, such as the air introduced into the room from the outside (fresh air), such as the air flowing into the first room from the second room. The difference between the current first indoor temperature of the first room and the current first temperature of the set temperature is calculated, and the target temperature promotion coefficient is positively correlated with the current first temperature difference. Then, the promoting effect of the air flowing into the first room from the second room on the temperature change process of the first room is eliminated to obtain the promoting effect of the air flowing into the first room from the outside on the temperature change process of the first room, and the target fresh air power of the fresh air device set in the first room is calculated accordingly. In the process where the current first indoor temperature of the first room does not reach the set temperature, the current first indoor temperature of the first room can be made to reach and stabilize at the set temperature relatively quickly, or stabilize at the set temperature, thereby shortening the time required for the indoor temperature fluctuation process of the first room.

[0060] Figure 2 This is a flow chart of a control method for a fresh air device provided in an embodiment of the present application. This control method can be executed by a controller of the fresh air device; in a smart home scenario, it can also be executed by a server of the smart home system; if the fresh air device is a fresh air air conditioner, it can also be executed by the controller of the fresh air air conditioner.

[0061] A first fresh air device is provided in the first room, air flow occurs between the first room and the second room, and air flows from the second room into the first room. The execution process of the control method is accompanied by a temperature adjustment process in the first room.

[0062] Combine Figure 2 As shown, the control method of the fresh air device includes:

[0063] S201: Obtain a current first indoor temperature of a first room, a current second indoor temperature of a second room, a set temperature of the first room, and a current outdoor temperature of an outdoor environment.

[0064] The set temperature is the set temperature of the temperature control device for the first room. The execution of the control method for the fresh air device is accompanied by the temperature control device adjusting the temperature of the first room. This temperature adjustment process refers to the process of adjusting the indoor temperature of the first room from the current first indoor temperature to the set temperature.

[0065] The set temperature can be set by the user, or it can be recommended using an existing healthy temperature recommendation algorithm. By setting the same set temperature for the first and second rooms, the user's perception of hot and cold temperatures when moving between the first and second rooms is reduced, improving their thermal comfort experience.

[0066] The execution process of the control method of the fresh air device may be accompanied by the temperature adjustment process of the first room and the second room. The temperature adjustment process of the second room refers to the process of adjusting the indoor temperature of the second room from the current second indoor temperature to the set temperature.

[0067] The current first indoor temperature can be obtained through the first temperature sensor in the first room. The first temperature sensor can be set independently and can be set on the first fresh air device. When the first fresh air device and the air conditioner are independent devices, the first temperature sensor can also be set on the air conditioner.

[0068] The current second indoor temperature can be obtained through the second temperature sensor in the second room. The second temperature sensor can be set independently and can be set on the second fresh air device. When the second fresh air device and the air conditioner are independent devices, the second temperature sensor can also be set on the air conditioner.

[0069] The current outdoor temperature of the outdoor environment may be obtained through a third temperature sensor disposed outdoors.

[0070] In the case of heating, the temperature regulating device may be an air conditioner, an electric heater, an electric hot air heater or other heating equipment.

[0071] In the case of cooling, the temperature regulating device may be an air conditioner.

[0072] Furthermore, the air conditioner in the embodiment of the present application may be a multi-split air conditioner, a split air conditioner or a central air conditioner. A multi-split air conditioner refers to a system in which one outdoor unit corresponds to multiple indoor units, and a split air conditioner refers to a system in which one outdoor unit corresponds to one indoor unit.

[0073] S202. When the current first indoor temperature is lower than the current second indoor temperature, the current first indoor temperature is lower than the current outdoor temperature, and the current second indoor temperature is lower than the set temperature, or when the current first indoor temperature is higher than the current second indoor temperature, the current first indoor temperature is higher than the current outdoor temperature, and the current second indoor temperature is higher than the set temperature, obtain the current first temperature difference between the current first indoor temperature and the set temperature.

[0074] When the current first indoor temperature is lower than the current second indoor temperature, the current first indoor temperature is lower than the current outdoor temperature, and the current second indoor temperature is lower than the set temperature, the first room and the second room are heated at the same time. Since the current second indoor temperature is higher than the current first indoor temperature, the air flowing from the second room into the first room promotes the heating process of the first room; since the current outdoor temperature is higher than the current first indoor temperature, the air flowing from the outdoor into the first room promotes the heating process of the first room.

[0075] When the current first indoor temperature is greater than the current second indoor temperature, the current first indoor temperature is greater than the current outdoor temperature, and the current second indoor temperature is greater than the set temperature, the first room and the second room are cooled at the same time. Since the current second indoor temperature is lower than the current first indoor temperature, the air flowing from the second room into the first room promotes the cooling process of the first room; since the current outdoor temperature is lower than the current first indoor temperature, the air flowing from the outdoor into the first room promotes the cooling process of the first room.

[0076] In the embodiment of the present application, the promoting effect refers to: during the heating process of the first room, in addition to the regulating effect of the temperature regulating device of the first room, additional heat is provided to the first room, and the additional heat provided to the first room has a promoting effect on the heating process of the first room; during the cooling process of the first room, in addition to the regulating effect of the temperature regulating device of the first room, additional cooling is provided to the first room, and the additional cooling provided to the first room has a promoting effect on the cooling process of the first room.

[0077] S203 : Determine a target temperature promotion coefficient corresponding to the current first temperature difference according to the positive correlation between the temperature difference and the temperature promotion coefficient.

[0078] The temperature promotion coefficient in the positive correlation relationship is used to express the promoting effect of the temperature difference between the indoor temperature and the outdoor temperature of the first room, the fresh air rate of the fresh air device, the temperature difference between the indoor temperature of the first room and the indoor temperature of the second room, and the air flow rate from the second room to the first room on the temperature change process of the first room.

[0079] The temperature promotion coefficient in the positive correlation relationship can be expressed as follows: the temperature change in the indoor temperature of the first room caused by the air sucked into the first room from the outside and the air flowing into the first room from the second room per unit time; or, the sum of the heat or cold carried by the air sucked into the first room from the outside and the air flowing into the first room from the second room per unit time relative to the current first indoor temperature.

[0080] The heat carried by the air sucked from the outside into the first room per unit time relative to the current first indoor temperature specifically refers to the heat that can be released when the air sucked from the outside into the first room is cooled to the current first indoor temperature per unit time; the cooling capacity carried by the air sucked from the outside into the first room per unit time relative to the current indoor temperature specifically refers to the heat that needs to be absorbed when the air sucked from the outside into the first room is heated to the current first indoor temperature per unit time.

[0081] The heat carried by the air flowing from the second room into the first room per unit time relative to the current first indoor temperature specifically refers to: the heat released when the air flowing from the second room into the first room is cooled to the current first indoor temperature per unit time; the cooling capacity carried by the air flowing from the second room into the first room per unit time relative to the current first indoor temperature specifically refers to: the heat required to absorb when the air flowing from the second room into the first room is heated to the current first indoor temperature per unit time.

[0082] Given the positive correlation between the temperature difference and the temperature promotion coefficient, the fresh air rate of the fresh air device in the first room, corresponding to the minimum temperature promotion coefficient, and the air flowing from the second room into the first room, can ensure that the pressure difference between the first pressure in the first room and the outdoor pressure is greater than or equal to the preset minimum pressure. Typically, after fresh air is introduced into the room, a slightly positive pressure is maintained indoors. That is, air enters the room from the outside through the fresh air device and then seeps out through gaps in the room to the outside. Those skilled in the art can set the preset minimum pressure based on experience to suit the actual environment.

[0083] The positive correlation between the temperature difference and the temperature promotion coefficient can be obtained through experiments.

[0084] The positive correlation between the temperature difference and the temperature promotion coefficient can be stored in a database in the form of a one-to-one correspondence data table. After obtaining the current first temperature difference, the target temperature promotion coefficient corresponding to the current first temperature difference can be obtained by querying the database.

[0085] The positive correlation between the temperature difference and the temperature promotion coefficient can also be stored in the form of a formula. After obtaining the current first temperature difference, the current first temperature difference is substituted into the formula to obtain the target temperature promotion coefficient corresponding to the current first temperature difference.

[0086] S204: Obtain a first temperature promotion coefficient of the second room to the first room.

[0087] The first temperature promotion coefficient is positively correlated with the current second temperature difference between the current first indoor temperature and the current second indoor temperature: when other conditions remain unchanged, the greater the current second temperature difference, the greater the first temperature promotion, and the smaller the current second temperature difference, the smaller the first temperature promotion coefficient.

[0088] Optionally, obtaining the first temperature promotion coefficient of the second room to the first room includes: obtaining the current second temperature difference between the current first indoor temperature and the current second indoor temperature; obtaining the current air flow rate of the first room and the second room; determining the first temperature promotion coefficient corresponding to the current second temperature difference and the current air flow rate based on a first correspondence between the temperature difference, the air flow rate and the temperature promotion coefficient; the temperature promotion coefficient in the first correspondence is used to represent the promoting effect of the temperature difference between the first indoor temperature of the first room and the second indoor temperature of the second room, and the air flow rate from the second room to the first room on the temperature change process of the first room.

[0089] The current air flow rates of the first and second rooms can be obtained using a sensor disposed between the first and second rooms. Alternatively, the current first pressure of the first room and the current second pressure of the second room can be obtained; the current pressure difference between the current second pressure and the current first pressure can be calculated; and the current air flow rate corresponding to the current pressure difference can be determined based on the corresponding relationship between the pressure difference and the air flow rate.

[0090] The temperature promotion coefficient in the first correspondence can be expressed as follows: the temperature change in the indoor temperature of the first room caused by the air flowing from the second room into the first room per unit time; or, the heat or cold carried by the air flowing from the second room into the first room per unit time relative to the current first indoor temperature.

[0091] The heat carried by the air flowing from the second room into the first room per unit time relative to the current first indoor temperature specifically refers to: the heat that can be released when the air flowing from the second room into the first room is cooled to the current first indoor temperature per unit time; the cooling capacity carried by the air flowing from the second room into the first room per unit time relative to the current first indoor temperature specifically refers to: the heat that needs to be absorbed when the air flowing from the second room into the first room is heated to the current first indoor temperature per unit time.

[0092] The first correspondence between the temperature difference, the air flow rate and the temperature promotion coefficient can be stored in the database in the form of a one-to-one correspondence data table. After obtaining the current second temperature difference and the current air flow rate, the first temperature promotion coefficient corresponding to the current second temperature difference and the current air flow rate can be obtained by querying the database.

[0093] Alternatively, the first correspondence between the temperature difference, the air flow rate and the temperature promotion coefficient can be pre-stored in the form of a formula. After obtaining the current second temperature difference and the current air flow rate, the current second temperature difference and the current air flow rate are substituted into the formula to obtain the first temperature promotion coefficient corresponding to the current second temperature difference and the current air flow rate.

[0094] S205. Determine a target fresh air rate according to a temperature promotion coefficient difference between the target temperature promotion coefficient and the first temperature promotion coefficient.

[0095] The target fresh air rate is positively correlated with the temperature promotion coefficient difference. When other conditions remain unchanged, the greater the temperature promotion coefficient difference, the greater the target fresh air rate; the smaller the temperature promotion coefficient difference, the smaller the target fresh air rate.

[0096] Alternatively, determining the target fresh air rate based on the temperature promotion coefficient difference between the target temperature promotion coefficient and the first temperature promotion coefficient may include: obtaining the current third temperature difference between the current first indoor temperature and the current outdoor temperature; determining the target fresh air rate corresponding to the current third temperature difference and the temperature promotion coefficient difference based on a second correspondence between the temperature difference, the fresh air rate and the temperature promotion coefficient; the temperature promotion coefficient in the second correspondence is used to represent the temperature difference between the outdoor temperature and the first indoor temperature of the first room, and the promoting effect of the fresh air rate of the fresh air device on the temperature change process of the first room.

[0097] The temperature promotion coefficient in the second corresponding relationship can be expressed as follows: the temperature change in the indoor temperature of the first room caused by the air inhaled from the outside into the first room per unit time; or, the heat or cold carried by the air inhaled from the outside into the first room per unit time relative to the current first indoor temperature.

[0098] Among them, the heat carried by the air sucked into the first room from the outside relative to the current first indoor temperature per unit time specifically refers to: the heat that can be released when the air sucked into the first room from the outside is cooled to the current first indoor temperature per unit time; the cooling capacity carried by the air sucked into the first room from the outside relative to the current first indoor temperature per unit time specifically refers to: the heat required to absorb when the air sucked into the first room from the outside is heated to the current first indoor temperature per unit time.

[0099] The second correspondence between the temperature difference, the fresh air rate and the temperature promotion coefficient can be stored in the database in the form of a one-to-one correspondence data table. After obtaining the current third temperature difference and the temperature promotion coefficient difference, the target fresh air rate corresponding to the current third temperature difference and the temperature promotion coefficient difference can be obtained by querying the database.

[0100] Alternatively, the second correspondence between the temperature difference, the fresh air rate and the temperature promotion coefficient can be pre-stored in the form of a formula. After obtaining the current third temperature difference and the temperature promotion coefficient difference, the current third temperature difference and the temperature promotion coefficient difference are substituted into the formula to obtain the target fresh air rate corresponding to the current third temperature difference and the temperature promotion coefficient difference.

[0101] S206. Control the fresh air device according to the target fresh air rate.

[0102] The fresh air rate includes, but is not limited to, the following expressions: the fan speed of the fresh air device, the fan current of the fresh air device, and the flow velocity of the air in the fresh air device. Controlling the fresh air device according to the target fresh air rate means: when the fan speed is used to represent the fresh air rate, the fresh air device is operated at the target fan speed corresponding to the target fresh air rate; when the fan current is used to represent the fresh air rate, after the fresh air device is operated, the fan current passing through the fresh air device is set to the target fan current corresponding to the target fresh air rate; when the air flow velocity is used to represent the fresh air rate, after the fresh air device is operated, the air flow velocity passing through the fresh air device is set to the target air flow velocity corresponding to the target fresh air rate.

[0103] In a scenario where two rooms are heated up at the same time and the fresh air introduced into the two rooms can promote the heating process, the room with the lower temperature of the two rooms is the first room; in a scenario where two rooms are cooled down at the same time and the fresh air introduced into the two rooms can promote the cooling process, the room with the higher temperature is the first room; in the process where the temperatures of the two rooms change simultaneously, the following three situations may occur: in the first situation, the temperature difference between the indoor temperatures of the two rooms is large, and the current first temperature difference between the current first indoor temperature of the first room and the set temperature is large; in the second situation, the temperature difference between the indoor temperatures of the two rooms is small, and the current first temperature difference is large; in the third situation, the temperature difference between the indoor temperatures of the two rooms is small, and the current first temperature difference is small.

[0104] The target temperature promotion coefficient can represent the promoting effect of other factors besides the temperature regulating device in the first room on the temperature change process of the first room, such as the heat or cold carried by the fresh air introduced into the first room from the outside, and the heat or cold carried by the air flowing into the first room from the second room, which have a promoting effect on the temperature change process of the first room.

[0105] In the first and second cases mentioned above, the current first temperature difference is large. Since the target temperature promotion coefficient is positively correlated with the current first temperature difference, the target temperature promotion coefficient is large. Other factors except the temperature control device in the first room provide more heat to the first room when heating up and more cooling to the first room when cooling down, which is conducive to the current first indoor temperature of the first room changing to the set temperature relatively quickly; in the third case mentioned above, since the current first temperature difference is small, the target temperature promotion coefficient is small. Other factors except the temperature control device in the first room provide less heat to the first room when heating up and less cooling to the first room when cooling down, which causes less interference to the process of the temperature control device adjusting the first indoor temperature of the first room, shortens the time required for the first indoor temperature to stabilize at the set temperature, and makes the current first indoor temperature of the first room stabilize at the set temperature relatively quickly.

[0106] In summary, the control method of the fresh air device can enable the first indoor temperature of the first room to reach and stabilize at the set temperature more quickly.

[0107] In addition, air flows from the second room into the first room, and the air in the first room can seep out to the outside through the gaps in the first room.

[0108] The target temperature promotion coefficient is positively correlated with the current first temperature difference. When the current first temperature difference is large, the target temperature promotion coefficient is large, and the sum of the amount of air flowing from the second room into the first room and the amount of air sucked into the first room from the outside is large. Therefore, more air in the first room can be replaced to the outside, that is, the total amount of air that needs to be temperature-controlled in the first room is reduced. On the one hand, the temperature control rate of the first room is improved, and the larger current first temperature difference can be reduced more quickly. On the other hand, the energy consumption required by the temperature control device in the first room can be reduced.

[0109] When the current first temperature difference is small, the target temperature promotion coefficient is small, and the sum of the amount of air flowing from the second room into the first room and the amount of air sucked into the first room from the outside is small. The less air in the first room is replaced to the outside, that is, the temperature adjustment process of the first room is affected as little as possible, which can shorten the fluctuation process required for the indoor temperature of the first room to stabilize from the current first indoor temperature to the set temperature, so as to stabilize the indoor temperature of the first room to the set temperature as soon as possible.

[0110] Figure 3 This is a schematic diagram of a process for determining a positive correlation between a temperature difference and a temperature promotion coefficient provided in an embodiment of the present application.

[0111] Combine Figure 3 As shown in Figure 2, the determination of the positive correlation between the temperature difference and the temperature promotion coefficient includes:

[0112] S301: Obtain a first temperature difference threshold value that is positively correlated with the accuracy value of a temperature adjustment device in a first room, and determine a second temperature difference threshold value corresponding to the first temperature difference threshold value.

[0113] The first temperature difference threshold is used to represent the temperature difference between the first indoor temperature of the first room and the set temperature, and the second temperature difference threshold is used to represent the temperature difference between the first indoor temperature of the first room and the outdoor temperature when the temperature difference between the first indoor temperature of the first room and the set temperature is the first temperature difference threshold.

[0114] The second temperature difference threshold is related to the outdoor temperature. When the first temperature difference threshold remains unchanged, the second temperature difference threshold will also change with different outdoor temperatures. Each time the control method for the fresh air device provided in the embodiment of the present application is executed, the second temperature difference threshold can be recalculated based on the current outdoor temperature.

[0115] Generally speaking, the higher the accuracy of a thermostat, the smaller its accuracy value. For example, if the accuracy of the first thermostat is ±1°C and the accuracy of the second thermostat is ±0.5°C, then the accuracy of the second thermostat is higher than that of the first. The accuracy value of the first thermostat is 1, and the accuracy value of the second thermostat is 0.5.

[0116] In this step, when the first indoor temperature of the first room is lower than the set temperature, when the temperature difference between the first indoor temperature and the set temperature is a first temperature difference threshold, the first indoor temperature is still lower than the outdoor temperature; wherein the relationship between the set temperature and the outdoor temperature is not specifically limited;

[0117] When the first indoor temperature of the first room is greater than the set temperature, when the temperature difference between the first indoor temperature and the set temperature is a first temperature difference threshold, the first indoor temperature is still greater than the outdoor temperature; wherein, the relationship between the set temperature and the outdoor temperature is not specifically limited.

[0118] S302: Determine a minimum temperature promotion coefficient corresponding to a preset minimum pressure difference between the first room and the outdoors and a second temperature difference threshold.

[0119] The preset minimum pressure difference corresponds to the fresh air rate of the fresh air device. After the preset minimum pressure difference is determined, the fresh air rate corresponding to the preset minimum pressure difference can be determined.

[0120] The minimum temperature promotion coefficient has a positive correlation with the fresh air rate corresponding to the preset minimum pressure difference. Since the fresh air rate has a positive correlation with the preset minimum pressure difference, the minimum temperature promotion coefficient also has a positive correlation with the preset minimum pressure difference; the minimum temperature promotion coefficient has a positive correlation with the second temperature difference threshold.

[0121] Furthermore, the minimum temperature promotion coefficient corresponding to the preset minimum pressure difference between indoors and outdoors and the second temperature difference threshold can be determined in the following manner: based on the correspondence between the pressure difference and the fresh air rate, the minimum fresh air rate corresponding to the preset minimum pressure difference is determined; based on the second correspondence between the temperature difference, the fresh air rate and the temperature promotion coefficient, the minimum temperature promotion coefficient corresponding to the second temperature difference threshold and the minimum fresh air rate is determined.

[0122] S303: Obtain a preset third temperature difference threshold, and determine a fourth temperature difference threshold corresponding to the third temperature difference threshold.

[0123] The third temperature difference threshold is used to represent the temperature difference between the first indoor temperature and the set temperature of the first room. The third temperature difference threshold is greater than the first temperature difference threshold. The fourth temperature difference threshold is used to represent the temperature difference between the first indoor temperature and the outdoor temperature of the first room when the temperature difference between the first indoor temperature and the set temperature of the first room is the third temperature difference threshold. The fourth temperature difference threshold is related to the outdoor temperature. When the third temperature difference threshold remains unchanged, the outdoor temperature is different and the fourth temperature difference threshold is also different. Each time the control method of the fresh air device provided in the embodiment of the present application is executed, the fourth temperature difference threshold can be recalculated according to the current outdoor temperature.

[0124] S304: Determine a second temperature promotion coefficient corresponding to a fourth temperature difference threshold and a maximum fresh air rate of the fresh air device.

[0125] The second temperature promotion coefficient is used to represent the effect of air flowing from the outside into the first room on the temperature change process in the first room. The second temperature promotion coefficient has a positive correlation with the fourth temperature difference threshold, and the second temperature promotion coefficient has a positive correlation with the maximum fresh air rate of the fresh air device. For example, the second temperature promotion coefficient corresponding to the fourth temperature difference threshold and the maximum fresh air rate of the fresh air device can be determined as follows: based on the second correspondence between the temperature difference, the fresh air rate, and the temperature promotion coefficient, the second temperature promotion coefficient corresponding to the fourth temperature difference and the maximum fresh air rate is determined.

[0126] S305: Obtain a current second temperature difference between the current first indoor temperature and the current second indoor temperature.

[0127] S306: Obtain a third temperature promotion coefficient that is positively correlated with the current second temperature difference.

[0128] The third temperature promotion coefficient is used to represent the influence of the air flowing from the second room to the first room on the temperature change process of the first room.

[0129] Optionally, obtaining a third temperature promotion coefficient that is positively correlated with the current second temperature difference includes: obtaining the current air flow rate of the first room and the second room; and determining a third temperature promotion coefficient corresponding to the current second temperature difference and the current air flow rate based on a first correspondence between the temperature difference, the air flow rate and the temperature promotion coefficient.

[0130] S307: Determine the sum of the second temperature promotion coefficient and the third temperature promotion coefficient as the maximum temperature promotion coefficient.

[0131] S308: Establish a first mapping relationship between a first temperature difference threshold and a minimum temperature promotion coefficient.

[0132] S309: Establish a second mapping relationship between the third temperature difference threshold and the maximum temperature promotion coefficient.

[0133] S310: Determine a positive correlation between the temperature difference and the temperature promotion coefficient according to the first mapping relationship and the second mapping relationship.

[0134] For example, a formula is fitted to the relationship between the temperature difference and the promotion coefficient based on the first mapping relationship and the second mapping relationship to obtain a positive correlation between the temperature difference and the promotion coefficient. Alternatively, a neural network is used to learn sample data containing the first mapping relationship and the second mapping relationship so that the neural network can output a temperature promotion coefficient corresponding to the temperature difference.

[0135] Specifically, in determining the positive correlation between the temperature difference and the temperature promotion coefficient, in addition to the first mapping relationship and the second mapping relationship, those skilled in the art may also take the temperature difference between the first temperature difference threshold and the third temperature difference threshold, as well as other temperature promotion coefficients between the minimum temperature promotion coefficient and the maximum temperature promotion coefficient, to form an additional mapping relationship, and use the additional mapping relationship to determine the positive correlation between the temperature difference and the temperature promotion coefficient.

[0136] A conventional temperature control scheme can be used to control the fresh air air conditioner in the first room. For example, the current first temperature difference is input into a temperature control model to obtain a temperature control parameter output by the temperature control model, and the temperature adjustment device in the first room is controlled according to the temperature control parameter. The temperature control model is a default control algorithm in the air conditioner, such as the common proportional-integral-derivative control model. Those skilled in the art can adopt an appropriate temperature control model based on actual conditions. The temperature control parameter can correspond to the operating power of the air conditioner's compressor, the throttle valve opening of the air conditioner, or the speed of the air conditioner's outdoor unit fan.

[0137] Can also be combined Figure 4 As shown, the temperature adjustment process of the first room includes:

[0138] S401: Input the current first temperature difference into a temperature control model to obtain a temperature control parameter output by the temperature control model that corresponds to the current first temperature difference.

[0139] The temperature control model corresponds to the temperature adjustment device of the first room.

[0140] The temperature control model is a default control algorithm in air conditioners, such as a common proportional-integral-derivative control model, etc. Those skilled in the art may adopt an appropriate temperature control model according to actual conditions.

[0141] The temperature control parameter may correspond to the operating power of the compressor of the air conditioner, may correspond to the throttle valve opening of the air conditioner, and may also correspond to the fan speed of the outdoor unit of the air conditioner.

[0142] S402: Reduce temperature control parameters according to the target temperature promotion coefficient.

[0143] The temperature control parameter corresponds to the operating power of the temperature regulating device, and the operating power of the temperature regulating device corresponding to the reduced temperature control parameter is less than the operating power of the temperature regulating device corresponding to the temperature control parameter before the reduction.

[0144] S403: Control the temperature adjustment device of the first room according to the lowered temperature control parameter.

[0145] The power of the temperature regulating device when operating according to the lowered temperature control parameters is less than the power of the temperature regulating device when operating according to the temperature control parameters before the lowering.

[0146] When the current first indoor temperature is lower than the set temperature and lower than the current outdoor temperature, the heating power of the temperature regulating device when operating according to the lowered temperature control parameters is lower than the heating power when operating according to the temperature control parameters before the lowering.

[0147] When the current first indoor temperature is greater than the set temperature and the current first indoor temperature is greater than the current outdoor temperature, the cooling power of the temperature adjustment device when operating according to the lowered temperature control parameters is less than the cooling power when the temperature adjustment device operates according to the temperature control parameters before the reduction.

[0148] The above scheme is an exemplary scheme for the temperature control process of the first room provided by the present application. It should be understood that after adopting the control method of the fresh air device provided by the present application, even if the existing temperature control algorithm is used to control the temperature regulating device (such as air conditioning), the indoor temperature can be stabilized at the set temperature as expected and relatively quickly.

[0149] After adopting the above-mentioned solution for the temperature control process of the first room, it is beneficial to compensate for the control process of the indoor temperature based on the fresh air control process. On the one hand, it can reduce the energy consumption of the fresh air air conditioner to a certain extent, and on the other hand, it can make the change process of the indoor temperature more in line with expectations.

[0150] Furthermore, the larger the target temperature promotion coefficient is, the greater the difference between the power when the temperature adjustment device operates according to the temperature control parameters before the reduction and the power when the temperature adjustment device operates according to the temperature control parameters after the reduction.
