Detailed Description

It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an air conditioner in a hardware operating environment according to an embodiment of the present invention.

Wherein a communication bus 1002 is used to enable connective communication between these components. The user interface 1003 may comprise a Display screen (Display), an input unit such as keys, and the optional user interface 1003 may also comprise a standard wired interface, a wireless interface. The network interface 1004 may optionally include a standard wired interface, a wireless interface (e.g., a Wi-Fi interface). The Memory 1005 may be a Random Access Memory (RAM) or a non-volatile Memory (disk Memory). The memory 1005 may alternatively be a storage device separate from the processor 1001.

Those skilled in the art will appreciate that the configuration of the apparatus shown in fig. 1 does not constitute a limitation of an air conditioner, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.

As shown in fig. 1, a memory 1005, which is a storage medium, may include therein an operating system, a network communication module, a user interface module, and a non-feeling control program.

In the air conditioner shown in fig. 1, the network interface 1004 is mainly used for connecting an external network and performing data communication with other network devices; the user interface 1003 is mainly used for connecting to a user equipment and performing data communication with the user equipment; the device calls the non-wind-feeling control program stored in the memory 1005 through the processor 1001 and executes the non-wind-feeling control method provided by the embodiment of the invention.

Based on the hardware structure, the embodiment of the non-wind-sensing control method is provided.

Referring to fig. 2, fig. 2 is a flowchart illustrating a windless control method according to a first embodiment of the present invention.

In a first embodiment, the no-wind-feeling control method includes the steps of:

and S10, detecting the positions of the persons corresponding to the human body in the current environment when the air conditioner is in the no-wind mode.

It should be noted that the execution main body of the embodiment may be an air conditioner, such as a central air conditioner, or may also be another type of air conditioner, which is not limited in the embodiment. The air conditioner in this embodiment may have a no-wind-feeling mode, and may also have an operation mode of other types and functions, which is not limited in this embodiment.

It should be noted that, the air conditioner may be provided with a function of automatically detecting the position of a person, the function may be fixedly set when the air conditioner is shipped from a factory, or may be set by a user himself or herself when the air conditioner is used, which is not limited in this embodiment. For example, at least the following may exist: 1. the air conditioner is not provided with a function of automatically detecting the position of a person. 2. The air conditioner is provided with a function of automatically detecting the position of a person, and is set to be automatically started when the air conditioner leaves a factory. 3. The air conditioner is provided with a function of automatically detecting the position of a person, and a user can select to turn on or off the function through a remote controller.

It can be understood that when the air conditioner is in the no-wind mode, whether the air conditioner has the function of automatically detecting the position of the personnel at present can be detected, if the air conditioner does not have the function of automatically detecting the position of the personnel at present, a user is prompted to manually adjust the angle of the air guide strips, and the angle of the horizontal air guide strips is manually adjusted by the user. If the air conditioner has the function of automatically detecting the positions of the personnel at present, the positions of the personnel corresponding to the human body in the current environment can be automatically detected, and the angle of the horizontal air guide strip can be automatically adjusted.

In a specific implementation, the position of the person may be detected by the infrared human detection sensor every first preset TIME (TIME 1), and in addition, the position of the person may be detected by an apparatus such as an image sensor, which is not limited in this embodiment.

Further, the wind guide strips in this embodiment may include horizontal wind guide strips and vertical wind guide strips, and an initial horizontal wind guide strip angle may be set in advance to be A5, an initial vertical wind guide strip angle is B1, and an initial fan rotation speed is R5. A user can control the air conditioner to enter a no-wind-sense mode through a remote controller or an application program on terminal equipment and the like, and when an air conditioner internal unit receives a no-wind-sense entering signal, the air conditioner can operate according to the no-wind-sense mode. When the air conditioner just enters the no-wind-sense mode, the horizontal wind guide strips can be adjusted to the initial horizontal wind guide strip angle A5, the vertical wind guide strips are adjusted to the initial vertical wind guide strip angle B1, and the fan is controlled to operate according to the initial fan rotating speed R5. And when the state is kept and the operation lasts for a third preset TIME (TIME 3), the step of detecting the position of the person corresponding to the human body in the current environment is executed.

And S20, determining the angle of the target wind guide strip according to the position of the person.

It should be understood that after determining the person position, a corresponding target wind strip angle may be determined according to the person position, where the target wind strip angle may be a wind strip angle corresponding to a horizontal wind strip.

It is understood that, as shown in fig. 3, fig. 3 is a distribution diagram of room zones, and the room can be divided into 6 zones, i.e. zone 1, zone 2, zone 3, zone 4, zone 5 and zones other than

zones

1, 2, 3, 4 and 5, according to the detection range of the detection device attached to the inner panel. In addition to the above-mentioned dividing manner, the area may be divided by other manners, which is not limited in this embodiment.

It should be understood that corresponding preset angles may be set for different area ranges in advance, after the position of the person is determined, a target area range where the human body is located may be determined according to the position of the person, the preset angle corresponding to the target area range may be searched, and the searched preset angle may be used as the target air guide strip angle.

It can be understood that, as shown in fig. 4, fig. 4 is a control diagram of an automatic detection wind guide strip, after entering a non-wind-sensing mode, the horizontal wind guide strip continues to operate for a TIME3 at a default angle A5, and then each TIME the TIME1 of operation detects that the position of a person is located in a zone 1, a zone 2 or a zone 3, the angle of the horizontal wind guide strip operates according to a preset angle A5, and the rest of the zones operate according to a preset angle A1.

In a specific implementation, for example, if a human body is in the area 1, the target area range is the area 1, the preset angle corresponding to the searchable area is a preset angle A5, and the preset angle A5 may be used as the target wind guide strip angle.

And S30, adjusting the air guide strips of the air conditioner according to the target air guide strip angle.

It should be noted that, in the no-wind-sensation mode, only the angle of the horizontal wind guide strip needs to be adjusted according to the position of the person, and the angle of the vertical wind guide strip can be kept unchanged from the initial angle B1 of the vertical wind guide strip, that is, in the no-wind-sensation mode, the angle of the vertical wind guide strip is always B1.

It should be understood that after the target wind guide strip angle is determined, the horizontal wind guide strips of the air conditioner can be adjusted to the target wind guide angle, so that a human body can not feel a wind sensation in any area of a room by adjusting the horizontal wind guide strips, and the effect of no wind sensation is improved.

And S40, acquiring the current horizontal air guide strip angle corresponding to the horizontal air guide strip.

It should be understood that, the change of the angle of the air guide strips can affect the non-wind-sensation index, and meanwhile, in order to ensure that the refrigerating capacity of the air conditioner in a non-wind-sensation state meets the use requirement, the higher the rotating speed is, the better the rotating speed is under the condition of meeting the non-wind-sensation, so that the rotating speed of the fan can be correspondingly adjusted according to different angles of the air guide strips to meet the requirement of the non-wind-sensation index, and the requirement of the refrigerating capacity of the air conditioner is met.

It can be understood that in order to meet the requirements of refrigeration effect and capacity and meet the standard of the no-wind-sensation index, different fan rotating speeds corresponding to different angles can be set so as to improve the refrigeration effect of the no-wind-sensation state.

It can be understood that the current horizontal wind guide bar angle corresponding to the horizontal wind guide bar may be detected at intervals of a second preset TIME (TIME 2), where the current horizontal wind guide bar angle is the wind guide bar angle corresponding to the current horizontal wind guide bar.

And S50, adjusting the rotating speed of a fan of the air conditioner according to the current angle of the horizontal air guide strip.

It can be understood that the corresponding relationship between the horizontal air guide bar angle and the fan rotating speed can be preset, after the current horizontal air guide bar angle is determined, the target fan rotating speed corresponding to the current horizontal air guide bar angle can be searched according to the corresponding relationship, and then the fan rotating speed of the air conditioner is adjusted according to the target fan rotating speed, so that the refrigeration effect is improved.

And S60, when the current indoor environment temperature is less than or equal to a preset indoor temperature threshold value, determining a target superheat degree according to the current air supply temperature and the current superheat degree of the indoor unit.

It should be understood that, the change of the rotation speed of the fan not only affects the output of the capacity, but also affects the air supply temperature, and in the no-wind-sensation state, even if the highest rotation speed meeting the no-wind-sensation index requirement is used under different wind guide strip angles, the air volume of the internal machine is also relatively small, the air supply temperature is relatively low, and although no wind sensation exists, the cold sensation of the air supply affects the use effect of a user.

When the temperature is quickly reduced to the set temperature, the system is in small-load refrigeration, for a multi-split system, because the discharge capacity of the compressor is large, when the temperature is reduced to the lowest frequency of the allowed operation of the compressor, the output of the outer machine is larger than that of the inner machine, the air quantity of the inner machine is smaller than that of the inner machine in a no-wind-sense state, the air supply temperature is lower, and although no wind sense exists, the cold sense of the air supply influences the use effect of a user. This scheme can be under the condition of no wind-sensing, makes the interior machine reach predetermined interior machine air supply temperature through changing predetermined interior machine superheat degree, has fallen to under the minimum condition in the outer quick-witted output, continues to reduce the refrigerant flow that gets into the interior machine, when satisfying the refrigeration effect, promotes air supply temperature's travelling comfort.

It should be understood that, in the no-wind mode, the ambient temperature detection may be performed to obtain the current indoor ambient temperature T1, and the current indoor ambient temperature T1 is compared with the preset indoor set temperature threshold TS to determine whether the current indoor ambient temperature T1 is less than or equal to the preset indoor set temperature threshold TS. The preset indoor set temperature threshold TS may be a parameter preset according to an actual situation, and the specific value is not limited in this embodiment.

It can be understood that if the current indoor environment temperature T1 is less than or equal to the preset indoor set temperature threshold TS, the current air supply temperature Tsf and the current superheat SH of the indoor unit of the air conditioner may be further obtained, and the target superheat suitable for the current use condition is determined according to the current air supply temperature Tsf and the current superheat SH.

And S70, controlling the opening of an electronic expansion valve of the indoor unit according to the target superheat degree.

It should be understood that after the target superheat degree is determined, the opening degree of the electronic expansion valve of the indoor unit can be adjusted according to the target superheat degree, so that the indoor unit reaches the preset indoor unit air supply temperature, and the problem that the air supply cold feeling influences the use effect of a user is further solved. Thereby satisfying refrigeration effect, having promoted air supply temperature's travelling comfort, still realized the effect of no cold sense on the basis of no wind sense, further improve user's use and experience.

In the embodiment, aiming at the condition that the whole condition can not satisfy the no wind feeling and part of special areas can not satisfy the no wind feeling under the no wind feeling state, under the no wind feeling mode, the position of a person is automatically detected to determine the target air guide strip angle so as to adjust the air guide strip of the air conditioner, the rotating speed of the fan is adjusted according to the current horizontal air guide strip, the target superheat degree is determined according to the current air supply temperature and the current superheat degree of the indoor unit under the condition that the indoor temperature is lower, and the opening degree of an electronic expansion valve of the indoor unit is adjusted according to the target superheat degree, so that the no wind feeling is realized, the no cold feeling is realized on the basis of the no wind feeling, the condition that a user feels uncomfortable can be avoided, and the no wind feeling of the user is improved.

In an embodiment, as shown in fig. 5, a second embodiment of the non-wind-feeling control method according to the present invention is proposed based on the first embodiment, and the step S50 includes:

and S501, determining the rotating speed of a target fan according to the angle of the current horizontal wind guide strip.

It should be understood that corresponding fan rotation speeds can be set for different wind guide strip angles in advance, and a corresponding relation between the wind guide strip angles and the fan rotation speeds is established. After the current horizontal wind guide strip angle is determined, the target fan rotating speed corresponding to the current horizontal wind guide strip angle can be determined according to the corresponding relation between the wind guide strip angle and the fan rotating speed.

And S502, adjusting the fan rotating speed of the air conditioner according to the target fan rotating speed.

It can be understood that, after the target fan rotation speed is determined, the fan rotation speed of the air conditioner may be adjusted according to the target fan rotation speed, so that the fan of the air conditioner operates at the target fan rotation speed.

In a specific implementation, as shown in fig. 6, fig. 6 is a control logic diagram of the non-wind-sensing wind guiding mechanism, and an angle A1 may be set to correspond to a preset rotation speed R1, an angle A2 corresponds to a preset rotation speed R2, an angle A3 corresponds to a preset rotation speed R3, an angle A4 corresponds to a preset rotation speed R4, and an angle A5 corresponds to a preset rotation speed R5.

The current horizontal wind guide angle can be detected every TIME2, and the rotating speed of the fan is adjusted according to the current wind guide strip angle, for example, when the current wind guide strip angle is an angle A1, the rotating speed of the fan is adjusted to a preset rotating speed R1; when the current angle of the wind guide strip is an angle A2, adjusting the rotating speed of the fan to a preset rotating speed R2; when the current angle of the air guide strip is an angle A3, adjusting the rotating speed of the fan to a preset rotating speed R3; when the current angle of the wind guide strip is an angle A4, adjusting the rotating speed of the fan to a preset rotating speed R4; when the angle of the current wind guide strip is an angle A5, the rotating speed of the fan is adjusted to a preset rotating speed R5.

In this embodiment, adjust the fan rotational speed according to current horizontal wind-guiding strip angle, optimized the refrigeration ability when guaranteeing the wind sense, improved refrigeration effect and user experience. Thereby change the regional position of air supply and air supply intensity through adjusting wind-guiding strip angle and fan rotational speed, when satisfying no wind requirement, promoted refrigeration effect, further promoted user experience.

In an embodiment, as shown in fig. 7, a third embodiment of the non-wind-feeling control method according to the present invention is proposed based on the first embodiment or the second embodiment, and in this embodiment, the description is made based on the first embodiment, and the step S60 includes:

step S601, when the current indoor ambient temperature is less than or equal to the preset indoor temperature threshold, comparing the current air supply temperature of the indoor unit with the preset air supply temperature.

It should be appreciated that in the case where the indoor temperature is low, the current air supply temperature Tsf may be compared with the preset air supply temperature Tsf0 to determine whether the current air supply temperature Tsf is less than the preset air supply temperature Tsf0. The preset blowing temperature Tsf0 may be a parameter preset according to an actual situation, and the present embodiment does not limit a specific value thereof.

And step S602, comparing the current superheat degree of the indoor unit with a first preset superheat degree when the current air supply temperature is lower than a preset air supply temperature.

It can be understood that if the current air supply temperature Tsf is less than the preset air supply temperature Tsf0, the current superheat SH of the air conditioner indoor unit is further obtained, and the current superheat SH is compared with the first preset superheat to determine whether the current superheat SH is less than the first preset superheat. The first preset superheat degree is a preset maximum superheat degree SHmax of the internal unit, and may be a preset parameter, and the specific value is not limited in this embodiment.

And step S603, when the current superheat degree is smaller than a first preset superheat degree, determining a target superheat degree according to the current superheat degree and a first preset constant.

It should be understood that if the current degree of superheat SH is less than the first preset degree of superheat, the current degree of superheat SH may be added to a first preset constant to calculate a first candidate degree of superheat, and the first candidate degree of superheat is taken as a target degree of superheat, and since the degree of superheat of the indoor unit of the air conditioner is related to the opening degree of the electronic expansion valve, the opening degree of the electronic expansion valve of the indoor unit may be adjusted according to the target degree of superheat. The first preset constant may be set in advance according to an actual situation, for example, the first preset constant may be set to 1, and may also be set to other values, which is not limited in this embodiment.

It can be understood that after the opening degree of the electronic expansion valve of the internal machine is adjusted according to the target superheat degree, time can be recorded, and after the interval Xmin, the step of comparing the current air supply temperature of the internal machine with the preset air supply temperature can be returned to be executed.

And step S604, when the current superheat degree is larger than or equal to a first preset superheat degree, taking the current superheat degree as a target superheat degree.

It should be understood that if the current degree of superheat SH is equal to or greater than the first preset degree of superheat, the current degree of superheat may be taken as a target degree of superheat, and then the opening degree of the electronic expansion valve of the indoor unit is adjusted according to the target degree of superheat.

Further, after comparing the current air supply temperature of the internal unit with the preset air supply temperature, the method further comprises the following steps:

when the current air supply temperature is greater than or equal to the preset air supply temperature, determining a target air supply temperature according to the preset air supply temperature and a preset return difference value; and when the current air supply temperature is less than or equal to the target air supply temperature, taking the current superheat degree as a target superheat degree.

It should be understood that, if the current air supply temperature Tsf is greater than or equal to the preset air supply temperature Tsf0, the preset air supply temperature Tsf0 and the preset return difference value may be added to obtain the target air supply temperature, and the current air supply temperature Tsf and the target air supply temperature are compared to determine whether the current air supply temperature Tsf is greater than the target air supply temperature. The preset back difference value may be a parameter preset according to an actual situation, for example, may be set to a value such as 1, 2, and may also be set to another value, and this embodiment does not limit the specific value thereof.

It is understood that if the current air supply temperature Tsf is not greater than the target air supply temperature, the current degree of superheat may be taken as the target degree of superheat, and then the opening degree of the electronic expansion valve of the indoor unit is adjusted according to the target degree of superheat

It can be understood that if the current air supply temperature Tsf is greater than the target air supply temperature, the current superheat SH of the air conditioner indoor unit is further obtained, and the current superheat SH is compared with a second preset superheat to determine whether the current superheat SH is greater than the second preset superheat. The second preset superheat degree is a preset minimum superheat degree SHmax of the internal unit, and may be a preset parameter, and the embodiment does not limit a specific value thereof.

It should be understood that if the current degree of superheat SH is not greater than the second preset degree of superheat, the current degree of superheat may be taken as the target degree of superheat and then based on the target degree of superheat.

It should be understood that if the current degree of superheat SH is greater than the second preset degree of superheat, the current degree of superheat SH may be subtracted from the second preset constant to calculate a second candidate degree of superheat, and the second candidate degree of superheat is taken as a target degree of superheat, and since the degree of superheat of the indoor unit of the air conditioner is related to the opening degree of the electronic expansion valve, the opening degree of the electronic expansion valve of the indoor unit may be adjusted according to the target degree of superheat. The second preset constant can be preset according to actual conditions, and the first preset constant can be the same as or different from the second preset constant. For example, the second predetermined constant may also be set to 1, and may also be set to other values, which is not limited in this embodiment.

In a specific implementation, as shown in fig. 8, fig. 8 is a control diagram for improving comfort of the supply air temperature, and in a no-wind mode, if the indoor ambient temperature T1 is less than or equal to a preset indoor set temperature threshold TS, that is, when the temperature shutdown is reached, it can be considered that the requirement of the user on the room temperature is met, and at this time, comfort of the user can be improved by optimizing the supply air temperature. Through the control logic, the air supply temperature can be judged once every X minutes, and then the opening degree of an electronic expansion valve of the internal machine is adjusted according to the determined target superheat degree.

In the embodiment, the target superheat degree suitable for the current situation is determined according to the current air supply temperature and the current superheat degree so as to adjust the opening degree of the electronic expansion valve of the internal machine, and the problem that the air supply cold feeling influences the use effect of a user is further solved. Thereby satisfying refrigeration effect, having promoted air supply temperature's travelling comfort, still realized the effect of no cold sense on the basis of no wind sense, further improve user's use and experience.

Furthermore, an embodiment of the present invention further provides a storage medium, where the storage medium stores a non-wind-sensation control program, and the non-wind-sensation control program, when executed by a processor, implements the steps of the non-wind-sensation control method described above.

Since the storage medium adopts all technical solutions of all the above embodiments, at least all the beneficial effects brought by the technical solutions of the above embodiments are achieved, and details are not repeated herein.

Further, referring to fig. 9, an embodiment of the present invention further provides a non-wind-sensing control apparatus, including:

and the position detection module 10 is used for detecting the positions of the persons corresponding to the human body in the current environment when the air conditioner is in the no-wind-sense mode.

It can be understood that when the air conditioner is in the no-wind-sense mode, whether the air conditioner has the function of automatically detecting the position of a person or not can be detected, if the air conditioner does not have the function of automatically detecting the position of the person or not, a user is prompted to manually adjust the angle of the air guide strips, and the user manually adjusts the angle of the horizontal air guide strips. If the air conditioner has the function of automatically detecting the positions of the personnel at present, the positions of the personnel corresponding to the human body in the current environment can be automatically detected, and the angle of the horizontal air guide strip can be automatically adjusted.

Further, the air guide strips in this embodiment may include horizontal air guide strips and vertical air guide strips, and an initial horizontal air guide strip angle may be set in advance to be A5, an initial vertical air guide strip angle to be B1, and an initial fan rotation speed to be R5. A user can control the air conditioner to enter a no-wind-sensation mode through a remote controller or an application program on terminal equipment and the like, and when an air conditioner internal unit receives a no-wind-sensation entering signal, the air conditioner can operate according to the no-wind-sensation mode. When the air conditioner just enters the no-wind-sense mode, the horizontal wind guide strips can be adjusted to the initial horizontal wind guide strip angle A5, the vertical wind guide strips are adjusted to the initial vertical wind guide strip angle B1, and the fan is controlled to operate according to the initial fan rotating speed R5. And when the state is kept and the operation lasts for a third preset TIME (TIME 3), the step of detecting the position of the person corresponding to the human body in the current environment is executed.

And the angle determining module 20 is configured to determine a target wind guide strip angle according to the position of the person.

It should be understood that after determining the person position, a corresponding target wind guide strip angle may be determined according to the person position, where the target wind guide strip angle may be a wind guide strip angle corresponding to a horizontal wind guide strip.

It is understood that, as shown in fig. 3, fig. 3 is a distribution diagram of room zones, and a room can be divided into 6 zones, i.e. zone 1, zone 2, zone 3, zone 4, zone 5 and zones other than

zones

1, 2, 3, 4, 5, according to the detection range of the detection device attached to the inner panel. In addition to the above-mentioned dividing method, the area may be divided by other methods, which is not limited in this embodiment.

It can be understood that, as shown in fig. 4, fig. 4 is a control diagram of the automatic detection wind guide strip, after the wind-sensing-free mode is entered, the horizontal wind guide strip continues to operate for a TIME3 at a default angle A5, and then each TIME the TIME1 is operated, when the position of the detector is located in the

areas

1, 2, and 3, the angle of the horizontal wind guide strip operates according to the preset angle A5, and the other areas operate according to the preset angle A1.

In a specific implementation, for example, if the human body is in the area 1, the target area range is the area 1, the preset angle corresponding to the searchable area is a preset angle A5, and the preset angle A5 may be used as the target wind guide strip angle.

And the air guide strip adjusting module 30 is used for adjusting the air guide strips of the air conditioner according to the target air guide strip angle.

And the information acquisition module 40 is used for acquiring the current horizontal air guide bar angle corresponding to the horizontal air guide bar.

It should be understood that the change of the angle of the air guide strips can affect the no-wind-sensation index, and meanwhile, in order to ensure that the refrigerating capacity of the air conditioner in the no-wind-sensation state meets the use requirement, the larger the rotating speed is, the better the rotating speed is under the condition of meeting the no-wind-sensation, so that the rotating speed of the fan can be correspondingly adjusted according to different angles of the air guide strips to meet the requirement of the no-wind-sensation index, and the requirement of the refrigerating capacity of the air conditioner is met.

And the rotating speed adjusting module 50 is used for adjusting the rotating speed of the fan of the air conditioner according to the current angle of the horizontal air guide strip.

It can be understood that the corresponding relation between the horizontal air guide bar angle and the fan rotating speed can be preset, after the current horizontal air guide bar angle is determined, the target fan rotating speed corresponding to the current horizontal air guide bar angle can be searched according to the corresponding relation, and then the fan rotating speed of the air conditioner is adjusted according to the target fan rotating speed, so that the refrigeration effect is improved.

And the target determining module 60 is used for determining the target superheat degree according to the current air supply temperature and the current superheat degree of the internal machine when the current indoor environment temperature is less than or equal to the preset indoor temperature threshold value.

It should be understood that the change of the fan rotating speed not only affects the capability output, but also affects the air supply temperature, and in the no-wind-sense state, even if the highest rotating speed meeting the no-wind-sense index requirement is used under different wind guide strip angles, the air volume of the internal machine is also small, the air supply temperature is low, and although no wind sense exists, the air supply cold sense affects the use effect of the user.

When the temperature is quickly reduced to the set temperature, the system is in small-load refrigeration, for a multi-split system, because the displacement of the compressor is large, when the temperature is reduced to the lowest frequency allowing the compressor to run, the output of the outer machine is larger than that of the inner machine, the air quantity of the inner machine is smaller than that of the inner machine in a non-air-sense state, the air supply temperature is lower, and although the air supply cold sense does not have the air sense, the use effect of a user is influenced. The scheme can enable the inner machine to reach the preset air supply temperature of the inner machine by changing the preset superheat degree of the inner machine under the condition of no wind sense, continuously reduce the flow of the refrigerant entering the inner machine under the condition that the output of the outer machine is reduced to the minimum, and improve the comfort of the air supply temperature while meeting the refrigeration effect.

It should be understood that, in the no-wind mode, the ambient temperature detection may be performed to obtain the current indoor ambient temperature T1, and the current indoor ambient temperature T1 is compared with the preset indoor set temperature threshold TS to determine whether the current indoor ambient temperature T1 is less than or equal to the preset indoor set temperature threshold TS. The preset indoor set temperature threshold TS may be a parameter preset according to an actual situation, and the embodiment does not limit a specific value thereof.

It can be understood that if the current indoor environment temperature T1 is less than or equal to the preset indoor set temperature threshold TS, the current air supply temperature Tsf and the current superheat SH of the air conditioner indoor unit may be further obtained, and the target superheat suitable for the current use situation may be determined according to the current air supply temperature Tsf and the current superheat SH.

And the opening degree adjusting module 70 is used for controlling the opening degree of an electronic expansion valve of the internal machine according to the target superheat degree.

It should be understood that after the target superheat degree is determined, the opening degree of the electronic expansion valve of the indoor unit can be adjusted according to the target superheat degree, so that the indoor unit reaches the preset indoor unit air supply temperature, and the problem that the air supply cold feeling affects the use effect of a user is further solved. Thereby satisfying refrigeration effect, having promoted air supply temperature's travelling comfort, still realized the effect of no cold sense on the basis of no wind sense, further improve user's use and experience.

In the embodiment, aiming at the situation that the whole air-free state can be met and the part of special areas can not meet the air-free state, in the air-free mode, the position of a person is automatically detected to determine the angle of a target air guide strip so as to adjust the air guide strip of the air conditioner, the rotating speed of a fan is adjusted according to the current horizontal air guide strip, the target superheat degree is determined according to the current air supply temperature and the current superheat degree of an indoor unit under the condition that the indoor temperature is low, and the opening degree of an electronic expansion valve of the indoor unit is adjusted according to the target superheat degree, so that the air-free state is realized, the cold-free state is realized on the basis of the air-free state, the uncomfortable condition of a user can be avoided, and the air-free feeling of the user is improved.
