It should be noted that the other mode is not a specified operation mode, and may be an operation mode other than the cooling mode and the heating mode, such as a dehumidification mode.
Preferably, the air supply mode can be operated when the air conditioner is not started, so that the stability of indoor temperature can be ensured when the air conditioner is not started by a user.
Further, in step S300, after the air conditioner is operated in the initial air supply mode, the indoor environment temperature and the outdoor environment temperature both change along with the time change, and after the indoor environment temperature reaches the set temperature, in order to avoid the influence of the external environment change on the indoor environment temperature, the outdoor load is prevented from entering the room by changing the air supply mode of the air conditioner, so that the air conditioner is easier to maintain the stability of the indoor temperature.
Further, in step S400, when the air supply mode is the induced air mode, the indoor air and the outdoor air are directly exchanged, and in general, the outdoor air enters the room through the air conditioner, the indoor air is replaced to other rooms through the door slits, and when the air supply mode is changed to the exhaust mode, the indoor air is exhausted to the outside, and the air in the other rooms is sent to the current room through the door slits.

s210, acquiring an outdoor environment temperature and an operation mode of an air conditioner;
s220, if the operation mode is a heating mode, when the outdoor environment temperature is smaller than the first target temperature, the air supply mode of the air conditioner is an air exhaust mode, and when the outdoor environment temperature is larger than the first target temperature, the air supply mode of the air conditioner is an induced air mode;
if the operation mode is a cooling mode, the air supply mode of the air conditioner is an air exhaust mode when the outdoor environment temperature is higher than the second target temperature, and the air supply mode of the air conditioner is an induced air mode when the outdoor environment temperature is lower than the second target temperature.

Further, in step S220, when the operation mode is the heating mode, the first target temperature is typically 10 ℃, and when the outdoor ambient temperature is less than 10 ℃, the outdoor load is large, and at this time, in order to avoid the external cool air directly entering the room, the air supply mode is controlled to be the air exhaust mode, and when the outdoor ambient temperature is greater than 10 ℃, the air supply mode is switched to be the air exhaust mode.
When the operation mode is the refrigeration mode, the second target temperature is 40 ℃ generally, when the outdoor environment temperature is higher than 40 ℃, the outdoor heat load is larger, at the moment, in order to avoid that the external hot air directly enters the room, the air supply mode is controlled to be an air exhaust mode, and when the temperature is lower than 40 ℃ along with the change of the outdoor environment, the air supply mode is switched to the air exhaust mode.
Preferably, the values of the first target temperature and the second target temperature can be adjusted according to different geographic environments, so that the switching of the air supply modes can meet more use scenes.
Through the combination of outdoor ambient temperature and running mode, let the air conditioner can be according to the quick initial air supply mode of determination of current environment, let indoor temperature change to user's wanted temperature as early as possible to can carry out the switching of air supply mode according to external environment's change, let indoor user experience better.
Controlling an air supply mode of the air conditioner according to the indoor environment temperature and the set temperature, comprising:
s310, when the operation mode is the heating mode:
s311, if the air supply mode of the air conditioner is an air exhaust mode, switching the air supply mode into an induced air mode when the set temperature-indoor environment temperature is less than or equal to a first threshold value;
s312, if the air supply mode of the air conditioner is the induced air mode, when the set temperature-indoor environment temperature is more than the second threshold value, the air supply mode is switched to the exhaust mode.
Further, in step S311, the outdoor load is larger, the outdoor load is prevented from entering the room by the air exhaust mode, and then the indoor environment temperature is compared with the set temperature, the first threshold is usually 0 ℃, i.e. when the indoor environment temperature is higher than the set temperature, the user feels hotter at the current temperature, so that in order to improve the comfort of the user, the air exhaust mode is switched to the air induction mode, the external cool air is allowed to enter the room, the indoor environment temperature is reduced to the vicinity of the set temperature, and the indoor environment temperature is kept at the set temperature as much as possible.
Further, in step S312, the temperature of the indoor environment is reduced by entering the external load, and the second threshold is typically 3 ℃, that is, when the deviation between the indoor environment temperature and the temperature required by the user is large, the air supply mode is switched to the air exhaust mode to increase the indoor environment temperature, and in step S311, if the indoor environment temperature is lower than the set temperature due to too much cool air entering the indoor, the step in S312 is performed to increase the indoor environment temperature to the vicinity of the temperature set by the user.
For example, the outdoor temperature is 11 ℃, the indoor temperature is 25 ℃, the set temperature is 26 ℃, the air supply mode is an air exhaust mode, external cold air is prevented from entering, the indoor temperature is increased, when the indoor temperature is increased to 27 ℃, the indoor temperature is higher, in order to reduce the indoor temperature to the vicinity of 26 ℃, the air supply mode is switched to the induced air mode, the outdoor cold air enters the room for cooling, when the indoor temperature is lower than 23 ℃, the air supply mode is switched back to the air exhaust mode, and the indoor temperature is prevented from continuously reducing.
Preferably, the automatic mode has an interval between switching between the air intake mode and the air exhaust mode, and the switching determination is performed once, usually for 15 minutes, so that the temperature is prevented from being repeatedly switched when the temperature reaches the vicinity of the set temperature.
Preferably, the values of the first threshold and the second threshold can be changed according to the living habit of the user, so that the practicability of the control method is improved.
When the air conditioner works in the heating mode, the first threshold value and the second threshold value are set to enable the air inducing mode and the air exhausting mode to have the switching standard, so that the temperature of the air conditioner can be kept within a comfortable range and is as close to the temperature set by a user as possible in the working process of the air conditioner.
The air supply mode of the air conditioner is controlled according to the indoor environment temperature and the set temperature, and the air conditioner further comprises:
s320, when the operation mode is the cooling mode:
s321, if the air supply mode of the air conditioner is an air exhaust mode, switching the air supply mode into an induced air mode when the indoor environment temperature-set temperature is less than or equal to a third threshold value;
s322, if the air supply mode of the air conditioner is the induced air mode, when the indoor environment temperature-set temperature is more than the fourth threshold value, the air supply mode is switched to the exhaust mode.
Further, in step S321, the outdoor heat load is larger, the external load is prevented from entering the room by the air exhaust mode, and then the indoor environment temperature is compared with the set temperature, the third threshold is usually 0 ℃, that is, when the indoor environment temperature is smaller than the set temperature, the user feels colder at the current temperature, so that in order to improve the comfort of the user, the air exhaust mode is switched to the air induction mode, the external hot air is allowed to enter the room, the indoor environment temperature is raised to the vicinity of the set temperature, and the indoor environment temperature is kept at the set temperature as much as possible.
Further, in step S322, the temperature of the indoor environment is raised by the entering of the external load, the second threshold is usually 3 ℃, that is, when the indoor environment temperature is higher than the set temperature, the user feels hotter, and at this time, the air supply mode is switched to the air exhaust mode, so as to avoid the entering of the external hot air, and the indoor temperature can be reduced, and it should be noted that, in step S321, if the indoor environment temperature is higher than the set temperature due to the excessive hot air entering the indoor, the step in S322 is performed so as to reduce the indoor environment temperature to the vicinity of the temperature set by the user.
For example, the outdoor temperature is 39 ℃, the indoor temperature is 27 ℃, the set temperature is 26 ℃, the air supply mode is an air exhaust mode, the entry of external hot air is avoided, the indoor temperature is reduced, when the indoor temperature is reduced to 25 ℃, the indoor temperature is lower, in order to increase the indoor temperature to the vicinity of 26 ℃, the air supply mode is switched to the induced air mode, the outdoor hot air is led into the room for cooling, and when the indoor temperature is higher than 29 ℃, the air supply mode is switched back to the air exhaust mode, so that the indoor temperature is prevented from continuously rising.
Preferably, the values of the third threshold and the fourth threshold can be changed according to the living habit of the user, so that the practicability of the control method is improved.
The set temperature of the air conditioner in the operation cooling mode is different from the set temperature of the air conditioner in the operation heating mode.
When the air conditioner works in the refrigeration mode, the third threshold value and the fourth threshold value are set to ensure that the induced air mode and the exhaust air mode have the switching standard, so that the temperature can be kept within a comfortable range and is as close to the temperature set by a user as possible in the working process of the air conditioner.
The air supply mode of the air conditioner is controlled according to the indoor environment temperature and the set temperature, and the air conditioner further comprises:
s330, when the operation mode is other modes:
s331, calculating a difference value between the indoor environment temperature and the outdoor environment temperature;
s332, controlling the air supply mode of the air conditioner according to the difference value.
Further, in step S331, when the air conditioner is not operated in the cooling or heating mode, the detected outdoor environment temperature and the indoor environment temperature are obtained, and the difference between the indoor environment temperature and the outdoor environment temperature is compared to obtain a temperature difference.
Further, in step S332, when the temperature difference is large, the air conditioner is controlled to enter the air exhaust mode, and when the temperature difference is small, the air conditioner is controlled to enter the induced air mode, so as to avoid the influence of the outdoor environment temperature change on the indoor environment temperature.
Preferably, when the air conditioner is in the dehumidification mode, the humidity of the outdoor environment may be detected, and whether the humidity of the indoor environment is affected in the induced air mode may be determined, so as to control the air supply mode of the air conditioner.
The detection of the temperature difference enables the air conditioner to switch the air supply mode when the air conditioner does not operate or operates in other modes, and the indoor environment temperature is ensured to be stable.
Controlling an air supply mode of the air conditioner according to the difference value, comprising:
s332a, controlling the air conditioner to enter an induced air mode when the difference value between the indoor environment temperature and the outdoor environment temperature is within a target range;
and S332b, controlling the air conditioner to enter an air exhaust mode when the difference value between the indoor environment temperature and the outdoor environment temperature is out of the target range.
Further, in step S332a, the target range is usually within ±5 ℃, i.e. when the absolute value of the temperature difference is less than or equal to 5 ℃, the temperature difference between the inside and outside is not large, and the outside air is not influenced by the indoor temperature when being exchanged into the room, so that the air conditioner is controlled to enter the induced air mode.
Further, in step S332b, when the absolute value of the temperature difference is greater than 5 ℃, the air conditioner is controlled to enter the air exhaust mode in order to avoid the influence of the external environment on the indoor environment temperature.
For example, the outdoor temperature is 23 ℃, the indoor temperature is 20 ℃, the absolute value of the temperature difference is 3 ℃, the air conditioner is controlled to enter the induced air mode, and when the outdoor temperature is increased to 26 ℃, the absolute value of the temperature difference is 6 ℃, the indoor environment temperature is prevented from increasing, and the air conditioner is controlled to enter the exhaust mode.
When the air conditioner works in other modes and is not started, the setting of the target range enables the air induction mode and the air exhaust mode to have the switching standard, so that the temperature of the air conditioner can be kept within a comfortable range and is as close to the temperature set by a user as possible in the working process of the air conditioner.
Controlling a ventilation passage of an air conditioner according to an air supply mode, comprising:
s410, when the air supply mode of the air conditioner is an induced draft mode, inducing outdoor air into the room for ventilation;
s420, when the air supply mode of the air conditioner is an air exhaust mode, exhausting indoor air to the outside for ventilation;
when the indoor air is exhausted to the outside for ventilation, air is introduced from the space with the temperature lower than the outdoor environment temperature.
Further, in step S410, by introducing outdoor air into the room, the indoor environment temperature is brought closer to the outdoor environment temperature, and the outdoor air is directly ventilated by the ventilation device of the air conditioner, and the indoor air is replaced to another room through the door slit.
Further, in step S420, in the exhaust mode, the external load is larger, so as to avoid the fresh air with a larger external load from entering the room, the ventilation channel is changed to convey the indoor air to the outside, and the air in the adjacent room is replaced to the current room, thereby avoiding the rapid change of the indoor environment temperature.
For example, in hot summer, the outdoor temperature is high, and when the user controls the air conditioner to operate in the cooling mode, if the air supply mode is the induced air mode, the outdoor heat load is continuously introduced into the room, so as to affect the cooling effect of the air conditioner, for example, when the outdoor temperature is 43 ℃, the relative humidity is 50%, the indoor temperature is 27 ℃, the relative humidity is 50%, and the fresh air volume is 40m 3 And/h. The induced air mode can introduce 43 ℃ hot air into a room and replace 27 ℃ cold air in the room, the heat load is about 780W, the refrigeration effect is poor, if the exhaust mode is used, although the 27 ℃ cold air in the room is replaced, the air introduced into the room is not directly introduced from the outside, usually enters from other rooms through door gaps, and the room temperature is generally lower than the outdoor temperature, so the heat load is lower than that of the induced air mode, and the user experience is improved.
The arrangement of different ventilation channels can ensure that the ventilation mode is not single any more, so that more use scenes can be met, and the user experience is improved.
Referring to fig. 3 and 4, there is also provided a control device of an air conditioner, the control device including: the detection module 130, the detection module 130 is used for detecting the indoor environment temperature and the outdoor environment temperature; the control module 120, the control module 120 is used for controlling the air supply mode of the air conditioner and the ventilation channel in the air supply mode, and the control device is used for executing the control method described in the above embodiment.
The present invention also provides an air conditioner 100, the air conditioner 100 comprising a processor 121, a memory 131 and a program or instructions stored on the memory 131 and executable on the processor 121, the program or instructions implementing the steps of the control method described above when executed by the processor 121.
The present invention also provides a readable storage medium having stored thereon a program or instructions which, when executed by the processor 121, implement the steps of the control method as in the above-described embodiments.
Although the present invention is disclosed above, the present invention is not limited thereto. Various changes and modifications may be made by one skilled in the art without departing from the spirit and scope of the invention, and the scope of the invention should be assessed accordingly to that of the appended claims.
