step S10, when the heating device is in a heating state and the air conditioner is in an air supply mode, acquiring the ambient temperature in the air conditioner acting space; the air supply mode is an air conditioner running state that a compressor of the air conditioner is closed and an indoor fan is opened;
the space of operation of the air conditioner particularly means an indoor environmental area to which the environment conditioning function of the air conditioner can be radiated.
The heating state specifically refers to a state in which the heating apparatus is turned on and heat is input into the room.
In the air supply mode, the air conditioner only disturbs the airflow of the acting space, and does not exchange heat with the air in the space.
The ambient temperature in the space where the air conditioner is acting is obtained by acquiring data detected by a temperature sensor in the space, for example, data detected by a return air inlet temperature sensor of an indoor unit.
Step S20, determining the operation parameters of the indoor fan of the air conditioner according to the environment temperature and the set comfortable temperature; the set comfortable temperature is a user set parameter in the air supply mode;
the set comfort temperature specifically refers to a preset temperature that can satisfy the comfort needs of the user. The set comfortable temperature can be specifically input by a user through an instruction, and different users can set different set comfortable temperatures according to different comfortable requirements of the users. Wherein the set comfortable temperature is greater than the outdoor ambient temperature.
The operating parameters of the indoor fan specifically refer to the operating related parameters of the indoor fan. The operation parameters of the indoor fan specifically include an opening instruction of the indoor fan, a closing instruction of the indoor fan, a duration of continuous operation of the indoor fan, and/or rotation speed control parameters (a magnitude, a change rate, and/or a change direction of the rotation speed of the indoor fan, etc.) of the indoor fan.
Different environmental temperatures and set comfortable temperatures correspond to different operating parameters of the indoor fan. For example, different ambient temperatures and set comfort temperatures may have different operating parameters of the indoor fan corresponding to the ratio, difference, or average. Specifically, the corresponding relationship between the ambient temperature, the set comfortable temperature and the operating parameters of the indoor fan may be preset. The corresponding relation can be in the form of a calculation formula, a mapping table and the like. And determining the operating parameters of the indoor fan corresponding to the current environment temperature and the set comfortable temperature based on the corresponding relation. The determined operating parameter is a parameter that can change the current ambient temperature towards the set comfort temperature.
And step S30, controlling the indoor fan to operate according to the operation parameters.
The operation parameters comprise that when the indoor fan is started, the indoor fan is controlled to be started; controlling the indoor fan to be closed when the operation parameters comprise closing the indoor fan; when the operation parameters comprise the rotating speed of the indoor fan, controlling the indoor fan to operate according to the rotating speed; when the operation parameters include rotating speed adjusting parameters (such as change rate, adjusting amplitude and/or adjusting wind direction) of the indoor fan, the rotating speed of the indoor fan is controlled to increase or decrease the rotating speed according to the rotating speed adjusting parameters, and the like.
According to the control method of the air conditioner, the air conditioner is arranged on the basis of the heating device corresponding to the air outlet, when the heating device is in a heating state and the air conditioner is in an air supply mode, the operation parameters of the indoor fan are determined on the basis of the environment temperature of an acting space of the air conditioner and the set comfortable temperature, the indoor fan is controlled to operate according to the determined operation parameters, therefore, under the condition that the heating state of the heating device is fixed, the fan of the air conditioner is suitable for the actual condition and the comfortable requirement of the indoor environment temperature to be accurately regulated and controlled, the air supply effect of the air conditioner is matched with the heat dissipation of the heating device, the indoor environment temperature is accurately matched with the comfort of a user, and the comfort of the user is improved.
Specifically, in this embodiment, step S20 includes:
step S21, determining a temperature difference between the ambient temperature and the set comfort temperature;
specifically, if the ambient temperature is defined as T1 and the set comfort temperature is defined as Ts, the temperature difference Δ T is T1-Ts.
And step S22, determining the operation parameters of the indoor fan according to the temperature difference.
Different temperature difference values can correspond to different indoor fan rotating speeds, opening and closing instructions, duration of opening and closing and the like. For example, based on Δ T being T1-Ts, the greater Δ T, the smaller the rotation speed; the smaller the Δ T, the larger the rotation speed; alternatively, the longer Δ T is, the shorter the continuous on-time is, and the shorter Δ T is, the longer the continuous on-time is.
Specifically, in this embodiment, if the temperature difference is greater than a first set threshold, it is determined that the operating parameter is that the indoor fan is turned off; if the temperature difference is smaller than a second set threshold, determining that the operation parameters comprise starting the indoor fan; wherein the second set threshold is less than or equal to the first set threshold.
The specific size of the first set threshold and the second set threshold can be set according to actual conditions. Specifically, the first set threshold and the second set threshold may be set by a user; in addition, the first set threshold and the second set threshold may be set by a user or determined according to an actual operating condition of the air conditioner, and the corresponding first set threshold and the corresponding second set threshold which are different in operating condition are different, for example, a heating temperature of a heating device, an outdoor environment temperature, and the like. The first set threshold is specifically a value greater than 0, and the second set threshold may be set to a value greater than 0, equal to 0, or less than 0 according to actual requirements.
In this embodiment, the first set threshold is greater than the second set threshold. Specifically, the second set threshold may be determined based on the first set threshold and the set deviation. And defining the first set threshold as X, and then defining the second set threshold as X-A. For example, the first set threshold is 3 ℃ and the second set threshold is-2 ℃. It should be noted that, in other embodiments, the first set threshold may also be set equal to the second set threshold according to actual requirements.
The temperature difference is larger than a first set threshold value, which indicates that the current indoor environment temperature can meet the user comfort, and at the moment, the indoor fan is closed, so that the phenomenon that the user comfort is reduced because the excessive heat of the heating device is dissipated in the indoor environment to cause the indoor environment temperature to unnecessarily rise is avoided. The temperature difference is less than the second and sets for the threshold value, indicates that current indoor ambient temperature is lower, can not satisfy user's travelling comfort, opens the fan this moment, makes more heats of heating installation distribute in indoor environment, improves indoor ambient temperature to guarantee user's travelling comfort.
In this embodiment, the switching of indoor fan is controlled based on the relation between temperature difference and the first threshold value of setting for, the second threshold value of setting for, guarantees that the switching of indoor fan can match with the temperature travelling comfort demand of current indoor environment is accurate, realizes the effective improvement of indoor user's travelling comfort.
Further, based on the above embodiments, another embodiment of the control method of the air conditioner of the present application is provided. In this embodiment, the step S20 includes:
step S20a, determining the running speed of the indoor fan according to the temperature difference;
wherein the operation rotating speed is increased along with the increase of the temperature difference.
Different temperature difference values correspond to different operating speeds. The corresponding relationship between the temperature difference and the operation rotation speed can be preset, and can be a calculation formula, a mapping relationship and the like. The operating speed of the indoor fan corresponding to the current temperature difference value can be determined based on the corresponding relation. Specifically, when the corresponding relation is a calculation formula, the current operating speed of the indoor fan can be calculated through the temperature difference. For example, the calculation formula is N ═ a × Δ T, a is a conversion parameter between a preset temperature difference and an operating rotation speed, N is the operating rotation speed of the indoor fan, and Δ T is the temperature difference. And when the corresponding relation is a mapping table, inquiring the mapping table through the temperature difference, inquiring the mapping table based on the temperature difference, and taking the rotating speed which has the mapping relation with the temperature difference in the mapping table as the current operating rotating speed of the indoor fan.
In this embodiment, the skew degree of the actual temperature condition that the temperature difference value can accurate sign indoor environment and user's travelling comfort demand, consequently confirm the operating speed of indoor fan based on the temperature difference value, can guarantee the accurate adjustment through the fan rotational speed, can cooperate the current heating state of heating installation to make indoor environment adjust to with the accurate matching of the comfortable demand of user, guarantee the satisfying of user's travelling comfort.
Specifically, in the present embodiment, in the corresponding relationship, at least two set temperature difference intervals may be divided in advance, and different set temperature difference intervals correspond to different set rotation speeds. Based on this, corresponding rotational speed can be obtained as the operating rotational speed of indoor fan through the setting temperature difference interval that the temperature difference value is located. The number and the range of the set temperature difference ranges can be set according to actual requirements, and the set temperature difference ranges can be originally configured by a system and can also be set by a user. The set temperature difference interval can be set to be a continuous numerical interval or a discontinuous numerical interval according to actual requirements. Based on this, step S20a includes:
step S201, determining a first target interval in which the temperature difference value is located in at least two set temperature difference intervals;
step S202, acquiring a set rotating speed corresponding to the first target interval as the running rotating speed; the set rotating speed is increased along with the increase of the numerical value of the set temperature difference interval.
Specifically, referring to fig. 4, 7 set temperature difference sections (— ∞, X1), [ X1, X2), [ X2, X3), [ X3, X4), [ X4, X5), [ X5, X6), [ X6, +∞) may be divided in advance. A set maximum rotation speed of 0% for a set rotation speed corresponding to (-infinity, X1), [ X1, X2 ] a set maximum rotation speed of 1%, a set maximum rotation speed of 20% for a set rotation speed corresponding to [ X2, X3), [ X3, X4) a set maximum rotation speed of 40%, a set maximum rotation speed of 60% for a set rotation speed corresponding to [ X4, X5), [ X5, X6) a set maximum rotation speed of 80%, and a set maximum rotation speed of 100% for a set rotation speed corresponding to [ X6, + ∞). It should be noted that, in the present embodiment, the ambient temperature may be less than the set comfort temperature. Specifically, the temperature difference may be smaller than the second set threshold. The temperature difference specifically refers to an absolute value of a difference between the ambient temperature and the set comfort temperature, and is defined as X. Based on this, the indoor fan can be controlled to stop in X (∞, X1), the maximum set rotating speed of 60% of the operating rotating speed of the indoor fan can be determined in X4, X5), and the maximum set rotating speed of 60% of the operating rotating speed of the indoor fan can be determined in X6, and + ∞).
In this embodiment, the operating speed of the indoor fan is determined based on the temperature difference interval of the temperature difference value, so that the indoor fan adopts the same wind speed and speed when the temperature difference value is located in the same temperature difference interval, frequent adjustment of the rotating speed of the indoor fan caused by small-amplitude fluctuation of indoor environment temperature is avoided, and the operating stability of the indoor fan is improved while the comfort of indoor environment users is ensured.
It should be noted that the operation parameter may include one of an operation rotation speed and an on-off command of the fan, or may include both the operation rotation speed and the on-off command of the fan.

Step S300, determining the running frequency of a compressor according to the heating temperature;
the set temperature threshold specifically refers to a preset minimum temperature capable of effectively heating the indoor environment, and the specific size of the set temperature threshold can be set according to actual conditions. For example, the set temperature threshold may be determined according to the current outdoor environment temperature and the set deviation, and a temperature value higher than the outdoor environment temperature by the set deviation is used as the set temperature threshold; for another example, the set temperature threshold may be determined based on the set comfort temperature and the set deviation, and a temperature value higher than the set comfort temperature by the set deviation may be used as the set temperature threshold here.

And step S500, controlling the air conditioner to maintain the operation of the air supply mode.
When heating temperature is less than or equal to the set temperature threshold, it indicates that the heat that current heating installation gived off is lower, can't make current indoor environment temperature effectively promote, based on this, steerable air conditioner starts the mode of heating to according to the operation of the frequency control compressor that confirms, thereby realize the heating through the air conditioner and coordinate heating installation's heating with indoor environment adjustment to the temperature that satisfies user's travelling comfort simultaneously. When the heating temperature is higher than the set temperature threshold value, it indicates that the heat emitted by the current heating device is enough to adjust the current indoor environment temperature to the comfortable temperature of the user, and at this time, the air supply mode can be maintained to operate, and the operation parameters of the indoor fan are determined according to the steps in the above embodiment.

Note that the heating temperature is greater than the current temperature of the indoor environment. The deviation specifically refers to the absolute value of the difference between the heating temperature and the set comfort temperature. The larger the deviation amount is, the smaller the rotation speed correction parameter is. For example, if the operating rotational speed determined based on the indoor ambient temperature and the set comfort temperature is N and the rotational speed correction parameter is M, the corrected operating rotational speed N '═ N + M or N' ═ N × M.
