Technical Field

The application relates to the technical field of intelligent household appliances, and for example relates to a control method and device of a fresh air device and a fresh air conditioner.

Background

At present, the fresh air device and the temperature adjusting device are matched for use, and the indoor temperature and the indoor air freshness can be adjusted to be within a comfortable range of a user. And the fresh air device and the temperature adjusting device can be combined into a fresh air conditioner, and the indoor temperature and the indoor air freshness can be adjusted simultaneously by using one device. In the process of adjusting the indoor temperature, the indoor temperature and the outdoor temperature are generally different, and as fresh air is introduced from the outside into the indoor, the fresh air can interfere with the adjustment process of the indoor temperature, so that the indoor temperature is inconvenient to be stably adjusted to be within a comfortable temperature range of a user.

In some existing fresh air conditioner control processes, the indoor temperature and the outdoor temperature are obtained, the temperature difference between the indoor temperature and the outdoor temperature is calculated, the rotating speed of an indoor fan of the fresh air conditioner is finely adjusted according to the temperature difference, the relative quantity of the circulating quantity of the indoor air and the fresh air quantity is changed, so that the refrigerating/heating power of the air conditioner is adjusted, the temperature interference of the fresh air to the indoor temperature adjustment process is compensated, and the stability of the indoor temperature adjustment process is improved.

In addition, for two offices with ventilation in an office scene or two rooms with ventilation in a home scene, it is generally necessary to keep the temperatures of the two offices or the two rooms consistent, so that a user can walk between the two rooms, and better temperature experience is achieved. Because of normal activities of some work and life, such as meeting in office scenes, cooking in home scenes and the like, a larger temperature difference can occur between the temperatures of the two rooms, and in the heating process, heat in the room with higher temperature can flow to the room with lower temperature, and the heat flow has a promotion effect on the heating process of the room with lower temperature; during the cooling process, the cold in the room with lower temperature can flow to the room with higher temperature, and the heat flow has promotion effect on the cooling process of the room with higher temperature.

In some prior art, the outputs of the temperature adjusting devices of the two rooms can be respectively compensated based on the temperature differences of the two rooms, so that the temperatures of the two rooms can reach the set temperature relatively stably.

In the process of implementing the embodiment of the present application, it is found that at least the following problems exist in the related art:

for two rooms in which air flows, in order to adjust the temperature and air freshness of the two rooms, it is necessary to control the temperature adjusting device and the fresh air device of the two rooms, respectively. In the case where both the set temperature and the outdoor temperature are higher than the indoor temperatures of the two rooms, or in the case where both the set temperature and the outdoor temperature are lower than the indoor temperatures of the two rooms, the outdoor temperature has an accelerating effect on the temperature change process of the two rooms. At this time, if the heating power/refrigerating power of the air conditioners in the two rooms are respectively adjusted according to the temperature difference between the outdoor temperature and the indoor temperature, in the heating process, the room with lower indoor temperature has larger temperature difference with the outdoor, and more heating quantity needs to be reduced to compensate the influence of fresh air on the indoor temperature; in the cooling process, the temperature difference between the room with higher indoor temperature and the outdoor temperature is smaller to compensate the influence of the fresh air on the indoor temperature. By the compensation mode, the time required for stabilizing the indoor temperature of the room with lower temperature at the set temperature in the heating process is longer, and the time required for stabilizing the indoor temperature of the room with higher temperature at the set temperature in the cooling process is longer.

In addition, in the process of respectively compensating the indoor temperatures of the two rooms by utilizing the temperature difference between the two rooms, the heating power of the room with lower temperature in the heating process is reduced, the refrigerating power of the room with higher temperature in the cooling process is reduced, the time required for stabilizing the indoor temperature of the room with lower temperature in the heating process at the set temperature is also longer, and the time required for stabilizing the indoor temperature of the room with higher temperature in the cooling process at the set temperature is longer.

It should be noted that the information disclosed in the foregoing background section is only for enhancing understanding of the background of the present application and thus may include information that does not form the prior art that is already known to those of ordinary skill in the art.

As shown in fig. 1, the room R1 and the room R2 may be two rooms in a home scene, or may be two rooms in an office scene; there is an air flow between room R1 and room R2, e.g. room R1 is not fitted with a door, or room R1 is fitted with a door but is in an open state, room R1 is in communication with corridor C; room R2 is not equipped with a door, or room R2 is equipped with a door but the door is open, room R2 communicates with corridor C.

The condition that the current first indoor temperature is smaller than the current second indoor temperature, the current first indoor temperature is smaller than the current outdoor temperature, and the current second indoor temperature is smaller than the set temperature means that the first room and the second room are heated simultaneously, and the outdoor temperature is favorable for the condition that the first room and the second room are heated, for example, in noon in the late autumn and early winter, the indoor temperature of the sunny room is lower, and the outdoor temperature is higher than the indoor temperature; 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, which means that the first room and the second room are cooled simultaneously, and the outdoor temperature is favorable for the cooling of the first room and the second room, such as the rooms of a kitchen, a bathroom and the like, after the kitchen, the bathroom and the like are used, the indoor temperature is higher, and the outdoor temperature is lower than the higher indoor temperature.

In the process that 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 reach and stabilize at the set temperature relatively quickly, or the current first indoor temperature of the first room is stabilized at the set temperature, so that the time period required by the indoor temperature fluctuation process of the first room is shortened.

The control method of the fresh air device can be executed by a controller of the fresh air device; in the smart home scenario, the method can also be executed by a server of the smart home system; in the case that the fresh air device is a fresh air conditioner, the fresh air device can also be executed by a controller of the fresh air conditioner.

The first room is provided with a first fresh air device, air flows between the first room and the second room, the air flows into the first room from the second room, and the control method is executed along with the temperature regulation process of the first room.

Referring to fig. 2, the control method of the fresh air device includes:

s201, obtaining a current first indoor temperature of the first room, a current second indoor temperature of the second room, a set temperature of the first room, and a current outdoor temperature of the outdoor environment.

The set temperature is the set temperature of the temperature regulating device of the first room. The execution process of the control method of the fresh air device is accompanied with the temperature regulation process of the temperature regulation device on the first room. The temperature adjustment process refers to: and adjusting the indoor temperature of the first room from the current first indoor temperature to the set temperature.

The set temperature can be set by the user by himself, and the set temperature can be recommended by adopting the existing healthy temperature recommendation algorithm. The first room and the second room adopt the same set temperature, so that when a user moves between the first room and the second room, the temperature difference of the user can be reduced, and the temperature comfort experience of the user is improved.

The execution process of the control method of the fresh air device can be accompanied with the temperature regulation process of the first room and the second room. The temperature regulation process of the second room refers to: and adjusting the indoor temperature of the second room from the current second indoor temperature to the set temperature.

The current first indoor temperature may be obtained by a first temperature sensor of the first room, which may be provided independently, may be provided on the first fresh air device, and may also be provided on the air conditioner in case the first fresh air device and the air conditioner are independent devices, respectively.

The current second indoor temperature can be obtained through a second temperature sensor of the second room, the second temperature sensor can be independently arranged and can be arranged on the second fresh air device, and the second temperature sensor can also be arranged on the air conditioner under the condition that the second fresh air device and the air conditioner are independent devices respectively.

The current outdoor temperature of the outdoor environment may be obtained by a third temperature sensor provided outdoors.

Under the heating condition, the temperature regulating device can be heating equipment such as an air conditioner, an electric heater, electric hot air and the like.

In the case of refrigeration, the temperature adjusting device may be an air conditioner.

In addition, the air conditioner in the embodiment of the application can be a multi-split air conditioner, a split air conditioner or a central air conditioner. The split type air conditioner is characterized in that one outdoor unit corresponds to one indoor unit.

S202, when the current first indoor temperature is smaller than the current second indoor temperature, the current first indoor temperature is smaller than the current outdoor temperature, and the current second indoor temperature is smaller than the set temperature, or when the current first indoor temperature is larger than the current second indoor temperature, the current first indoor temperature is larger than the current outdoor temperature, and the current second indoor temperature is larger than the set temperature, a current first temperature difference value between the current first indoor temperature and the set temperature is obtained.

When the current first indoor temperature is smaller than the current second indoor temperature, the current first indoor temperature is smaller than the current outdoor temperature, and the current second indoor temperature is smaller than the set temperature, the first room and the second room are heated at the same time, and because the current second indoor temperature is larger than the current first indoor temperature, air flowing into the first room from the second room has a promotion effect on the heating process of the first room; since the current outdoor temperature is greater than the current first indoor temperature, air flowing into the first room from the outside has an accelerating effect on the temperature rising process of the first room.

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, the first room and the second room are cooled simultaneously, and because the current second indoor temperature is lower than the current first indoor temperature, air flowing into the first room from the second room has a promotion effect on the cooling process of the first room; since the current outdoor temperature is smaller than the current first indoor temperature, air flowing into the first room from the outside has an accelerating effect on the cooling process of the first room.

In the examples of the present application, the promotion means: in the heating process of the first room, besides the regulation function of the temperature regulation device of the first room, heat is additionally provided for the first room, so that the heat additionally provided for the first room has a promotion function on the heating process of the first room; in the cooling process of the first room, besides the regulation function of the temperature regulation device of the first room, the cooling capacity is additionally provided for the first room, so that the cooling capacity additionally provided for the first room has a promotion function on the cooling process of the first room.

S203, determining 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.

The temperature promotion coefficient in the positive correlation is used to represent the promotion 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 of the second room to the first room on the temperature change process of the first room.

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

The heat carried by the air sucked into the first room outdoors with respect to the current first indoor temperature in unit time is specifically: the unit time length is the heat which can be released when the air sucked into the first room from the outside is cooled to the current first indoor temperature; the amount of cold carried by the air drawn into the first room outdoors with respect to the current indoor temperature per unit length of time is specifically: the unit time is the amount of heat that needs to be absorbed by the air that is drawn into the first room from outside to raise the current first indoor temperature.

The amount of heat carried by the air flowing into the first room by the second room per unit time relative to the current first indoor temperature is specifically: the unit time length is the heat released by the air flowing into the first room from the second room to the current first indoor temperature; the amount of cold carried by the air flowing into the first room by the second room per unit length of time relative to the current first indoor temperature is specifically: the unit length of time is the amount of heat that needs to be absorbed by the air flowing into the first room from the second room to heat up to the current first indoor temperature.

In the positive correlation between the temperature difference and the temperature promotion coefficient, the fresh air rate of the fresh air device of the first room corresponding to the minimum temperature promotion coefficient and the air flowing into the first room from the second room can ensure that the pressure difference between the first pressure of the first room and the outdoor pressure is greater than or equal to the preset minimum pressure. In general, after fresh air is introduced into a room, the room is kept at a slight positive pressure, that is, air enters the room from the outside through a fresh air device and then seeps out to the outside through a gap of the room. The person skilled in the art can empirically set a preset minimum pressure in accordance with the actual environment.

The positive correlation of the temperature difference with the temperature coefficient of promotion can be obtained experimentally.

The positive correlation of the temperature difference and the temperature promotion coefficient may be stored in a database in the form of a one-to-one correspondence data table. After the current first temperature difference value is obtained, the target temperature promotion coefficient corresponding to the current first temperature difference value can be obtained by inquiring a database.

The positive correlation between the temperature difference and the temperature promotion coefficient can also be stored in the form of a formula, and after the current first temperature difference is obtained, the current first temperature difference is substituted into the formula, so that the target temperature promotion coefficient corresponding to the current first temperature difference can be obtained.

S204, obtaining a first temperature promotion coefficient of the second room to the first room.

The first temperature promotion coefficient is positively correlated with a current second temperature difference between a current first indoor temperature and a current second indoor temperature: under the condition that other conditions are not changed, the larger the current second temperature difference value is, the larger the first temperature promotion is, the smaller the current second temperature difference value is, and the smaller the first temperature promotion coefficient is.

Fig. 3 is a schematic diagram of a process for determining a positive correlation between a temperature difference and a temperature promotion coefficient according to an embodiment of the present application.

Referring to fig. 3, the determination of the positive correlation between the temperature difference and the temperature promotion coefficient includes:

s301, a first temperature difference threshold value positively correlated to the precision value of the temperature regulating device of the first room is obtained, and a second temperature difference threshold value corresponding to the first temperature difference threshold value is determined.

The first temperature difference threshold is used for representing a temperature difference between a first indoor temperature and a set temperature of the first room, and the second temperature difference threshold is used for representing a temperature difference between the first indoor temperature and an 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 first temperature difference threshold.

The second temperature difference threshold is related to the outdoor temperature, and when the first temperature difference threshold is unchanged, the outdoor temperature is different, and the second temperature difference threshold is also different. When the control method of the fresh air device provided by the embodiment of the application is executed each time, the second temperature difference threshold value can be recalculated according to the current outdoor temperature.

In general, the higher the accuracy of the temperature adjustment device, the smaller the accuracy value of the temperature adjustment device. For example, the first temperature adjusting means has a precision of ±1 ℃, the second temperature adjusting means has a precision of ±0.5 ℃, and then the second temperature adjusting means has a precision higher than the first temperature adjusting means, the first temperature adjusting means has a precision value of 1, and the second temperature adjusting means has a precision value of 0.5.

In this step, when the temperature difference between the first indoor temperature and the set temperature is the first temperature difference threshold value in the case where the first indoor temperature of the first room is smaller than the set temperature, the first indoor temperature is still smaller than the outdoor temperature; the relation between the set temperature and the outdoor temperature is not particularly limited;

The minimum temperature promotion coefficient has a positive correlation with the fresh air rate corresponding to the preset minimum pressure difference, and the minimum temperature promotion coefficient has a positive correlation with the preset minimum pressure difference because the fresh air rate 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.

Further, the minimum temperature promotion coefficient corresponding to the preset minimum pressure difference and the second temperature difference threshold value in the indoor and outdoor can be determined by the following manner: determining a minimum fresh air rate corresponding to a preset minimum pressure difference according to the corresponding relation between the pressure difference and the fresh air rate; and determining a minimum temperature promotion coefficient corresponding to the second temperature difference threshold and the minimum fresh air rate according to a second corresponding relation among the temperature difference, the fresh air rate and the temperature promotion coefficient.

The fourth temperature difference threshold is related to the outdoor temperature, and when the third temperature difference threshold is unchanged, the outdoor temperature is different, and the fourth temperature difference threshold is also different. When the control method of the fresh air device provided by the embodiment of the application is executed each time, the fourth temperature difference threshold value can be recalculated according to the current outdoor temperature.

S304, determining a fourth temperature difference threshold value and a second temperature promotion coefficient corresponding to the maximum fresh air rate of the fresh air device.

The second temperature promoting coefficient has a positive correlation with the fourth temperature difference threshold, and the second temperature promoting coefficient has a positive correlation with the maximum fresh air rate of the fresh air device. For example, the fourth temperature difference threshold, the second temperature promotion coefficient corresponding to the maximum fresh air rate of the fresh air device, may be determined as follows: and determining a second temperature promotion coefficient corresponding to the fourth temperature difference and the maximum fresh air rate according to a second corresponding relation among the temperature difference, the fresh air rate and the temperature promotion coefficient.

S305, obtaining a current second temperature difference value between the current first indoor temperature and the current second indoor temperature.

S306, obtaining a third temperature promotion coefficient positively correlated with the current second temperature difference value.

The third temperature promotion coefficient is used to represent the effect of air flowing from the second room to the first room on the temperature profile of the first room.

Optionally, obtaining a third temperature promotion coefficient positively correlated to the current second temperature difference value includes: obtaining a 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 according to the first corresponding relation among the temperature difference, the air flow rate and the temperature promotion coefficient.

S307, determining the sum of the second temperature acceleration coefficient and the third temperature acceleration coefficient as the maximum temperature acceleration coefficient.

S308, establishing a first mapping relation between the first temperature difference threshold and the minimum temperature promotion coefficient.

S309, establishing a second mapping relation between the third temperature difference threshold and the maximum temperature promotion coefficient.

S310, determining a positive correlation relation between the temperature difference and the temperature promotion coefficient according to the first mapping relation and the second mapping relation.

For example, according to the first mapping relation and the second mapping relation, formula fitting is performed on the relation between the temperature difference value and the promotion coefficient so as to obtain a positive correlation relation between the temperature difference value and the promotion coefficient. Or, the neural network is utilized to learn the sample data comprising the first mapping relation and the second mapping relation, so that the neural network can output the temperature promotion coefficient corresponding to the temperature difference value.

Specifically, in determining the positive correlation between the temperature difference and the temperature promotion coefficient, in addition to the first mapping and the second mapping, a person skilled in the art may also take the temperature difference between the first temperature difference threshold and the third temperature difference threshold, and other temperature promotion coefficients between the minimum temperature promotion coefficient and the maximum temperature promotion coefficient, to form an additional mapping, and determine the positive correlation between the temperature difference and the temperature promotion coefficient using the additional mapping.

The fresh air conditioner of the first room can be controlled by adopting a conventional temperature control scheme, for example: and inputting the current first temperature difference value into a temperature control model to obtain a temperature control parameter output by the temperature control model, and controlling a temperature regulating device of the first room according to the temperature control parameter. The temperature control model is a default control algorithm in the air conditioner, such as a common Proportional-Integral-derivative control (Proportional-Integral-Derivative control) model, and the like. Those skilled in the art can use a suitable temperature control model according to the actual situation. The temperature control parameter may correspond to a compressor operating power of the air conditioner, may correspond to a throttle opening of the air conditioner, and may also correspond to a rotational speed of an outdoor unit fan of the air conditioner.

As also shown in connection with fig. 4, the temperature adjustment process of the first room includes:

s401, inputting the current first temperature difference value into a temperature control model, and obtaining a temperature control parameter corresponding to the current first temperature difference value output by the temperature control model.

The temperature control model is a default control algorithm in the air conditioner, such as a common Proportional-Integral-derivative control (Proportional-Integral-Derivative control) model, and the like. Those skilled in the art can use a suitable temperature control model according to the actual situation.

The temperature control parameter may correspond to a compressor operating power of the air conditioner, may correspond to a throttle opening of the air conditioner, and may also correspond to a rotational speed of an outdoor unit fan of the air conditioner.

S402, reducing the temperature control parameter according to the target temperature promotion coefficient.

The temperature control parameter corresponds to the operating power of the temperature adjusting device, and the operating power of the temperature adjusting device corresponding to the temperature control parameter after reduction is smaller than the operating power of the temperature adjusting device corresponding to the temperature control parameter before reduction.

S403, controlling the temperature regulating device of the first room according to the reduced temperature control parameter.

The power of the temperature regulating device when operating according to the temperature control parameter after being reduced is smaller than the power of the temperature regulating device when operating according to the temperature control parameter before being reduced.

When the current first indoor temperature is smaller than the set temperature and the current first indoor temperature is smaller than the current outdoor temperature, the heating power of the temperature adjusting device when the temperature adjusting device operates according to the reduced temperature control parameter is smaller than the heating power of the temperature adjusting device when the temperature adjusting device operates according to the temperature control parameter before the temperature adjusting device is reduced.

And under the condition that 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 refrigeration power of the temperature regulating device when the temperature regulating device operates according to the reduced temperature control parameter is smaller than the refrigeration power of the temperature regulating device when the temperature regulating device operates according to the temperature control parameter before the reduction.

The foregoing is an exemplary embodiment of the present application for a temperature control process of a first room, and it should be understood that after the control method of the fresh air device provided by the present application is adopted, even if an existing temperature control algorithm is adopted to control a temperature adjustment device (such as an air conditioner), the indoor temperature can be stabilized at a set temperature as expected and relatively quickly.

After the scheme of the temperature control process related to the first room is adopted, the control process based on the fresh air is facilitated, the control process of the indoor temperature is compensated, on one hand, the energy consumption of the fresh air conditioner can be reduced to a certain extent, and on the other hand, the change process of the indoor temperature can be more expected.

Further, the larger the target temperature promotion coefficient, the larger the difference between the power at which the temperature adjusting device operates according to the temperature control parameter before being lowered and the power at which the temperature adjusting device operates according to the temperature control parameter after being lowered.
