The invention provides an air conditioner control method.
In an embodiment of the present invention, as shown in fig. 1, the air conditioner control method includes the steps of:
step S100, receiving a first preset instruction;
the first preset instruction is an instruction for controlling the air conditioner to avoid directly supplying air to a human body, and can be sent out by a user through a key or a key group on a remote controller or can be automatically generated by the air conditioner according to the current operation state or operation mode of the air conditioner. For example, in a specific example, a blow-through free function key is provided on a remote controller of an air conditioner, and a user can issue a first preset instruction by pressing the blow-through free function key. In another specific example, the operation mode of the air conditioner includes a person avoiding mode, and when the air conditioner operates in the person avoiding mode, the air conditioner automatically generates a first preset instruction according to the mode so as to avoid directly blowing air to a human body.
S200, when a first preset instruction is received, acquiring the current indoor temperature and the current air supply temperature;
since the heat transfer takes a certain time, there is a certain difference between the indoor temperature and the supply air temperature, particularly at the stage when the air conditioner starts to operate. In the case where other conditions are not changed, when the difference between the indoor temperature and the supply air temperature is large, the feeling of wind felt by the user is also large. Therefore, it is necessary to monitor the indoor temperature and the supply air temperature to adjust the supply air parameters of the air conditioner. The indoor temperature and the air supply temperature can be respectively obtained by temperature sensors which are arranged far away from the air outlet and close to the air outlet, and can also be obtained by reading the operating parameters of the air conditioner or the environmental parameters detected by other intelligent terminals (such as a mobile phone, a tablet personal computer and the like).
Step S300, comparing the indoor temperature with the air supply temperature;
the indoor temperature and the air supply temperature are compared so as to know the wind sensation condition possibly felt by the user in the current state.
And step S400, when the absolute value of the difference between the indoor temperature and the air supply temperature is greater than or equal to a first preset temperature difference, controlling the transverse air guide of the air conditioner to directly rotate to a first preset angle, and controlling the longitudinal air guide of the air conditioner to directly rotate to a second preset angle.
When the absolute value of the difference between the indoor temperature and the air supply temperature is larger than or equal to a first preset temperature difference, concretely, when the air conditioner operates in a refrigeration mode, the difference between the indoor temperature and the air supply temperature is larger than or equal to the first preset temperature difference, when the air conditioner operates in a heating mode, the difference between the air supply temperature and the indoor temperature is larger than or equal to the first preset temperature difference, the user can easily feel obvious wind sensation at the moment, the transverse air guide part of the air conditioner is controlled to directly rotate to the first preset angle, the longitudinal air guide part rotates to the second preset angle, the air supply direction deviates from the moving range of the user, so that the air supply direct blowing user is avoided, and the user experience is improved. As shown in fig. 2 and 3, the transverse air guide of the air conditioner is used for controlling the horizontal air supply direction of the air conditioner, i.e. controlling the air conditioner to supply air leftwards, towards the middle or towards the right. When the air conditioner is operated in a normal state, the transverse air guide is positioned to supply air to the middle as shown in fig. 2, so that the air supply range is wide, and the indoor temperature is promoted to reach the set temperature of a user as soon as possible. When the first preset instruction is received, in a specific example, the position of the transverse air guide is located at a first preset angle, as shown in fig. 3, the air supply of the air conditioner is deviated to one side, so as to avoid the air supply from directly blowing the user. The first preset angle and the second preset angle can be preset in the air conditioner according to an experiment or calculation result, and the ice can be manually set by a user according to the requirement of the user and stored in the air conditioner. When the first preset angle and the second preset angle are determined, in a specific experiment, whether a user can feel the direct blowing of air supplied by the air conditioner at each point can be judged by simulating the relation between the air supply wind field and the angles of the transverse air guide and the longitudinal air guide and taking the wind speed of each point in the space as a basis, and the optimized first preset angle and the optimized second preset angle are finally determined by further combining the feedback of experience personnel. In another specific experiment, the optimized first preset angle and the optimized second preset angle can be finally determined by further combining the feedback of experience personnel through the relationship between the temperature change conditions of each point in the test space and the angles of the transverse air guide and the longitudinal air guide. Meanwhile, the air supply direction is adjusted by combining the transverse air guide piece and the longitudinal air guide piece, and the circulation of indoor air under the condition that the indoor air is not directly blown to a user can be controlled, so that the uniformity of indoor temperature is improved, and the comfort of the air conditioner is improved.
In this embodiment, the air conditioner control method includes the steps of: receiving a first preset instruction; when the first preset instruction is received, acquiring the current indoor temperature and the current air supply temperature; comparing the indoor temperature with the air supply temperature; when the absolute value of the difference between the indoor temperature and the air supply temperature is larger than or equal to a first preset temperature difference, the transverse air guide piece of the air conditioner is controlled to directly rotate to a first preset angle, and the longitudinal air guide piece of the air conditioner is controlled to directly rotate to a second preset angle. Through receiving first instruction of predetermineeing, when receiving first instruction of predetermineeing, control air conditioner gets into the state of avoiding air supply direct-blow, it is concrete, combine indoor temperature and air supply temperature's comparison result, when the absolute value of the difference of indoor temperature and air supply temperature is greater than or equal to first predetermined difference in temperature, the wind sense that the user probably experienced this moment is stronger, acquire the current operational mode of air conditioner, adjust the angle of horizontal wind-guiding piece and vertical wind-guiding piece according to the operational mode, make the air supply of air conditioner skew user's home range, in order to avoid the air supply direct-blow human body. Through controlling the transverse air guide piece to directly rotate to a first preset angle, the longitudinal air guide piece directly rotates to a second preset angle, the process that a user manually adjusts the angle of the air guide piece is omitted, and the operation of the air conditioner is simplified. And the horizontal air guide piece has a wider range for adjusting air supply in the horizontal direction, and when the longitudinal air guide piece adjusts air supply in the vertical direction, the air supply range can be adjusted by combining the properties of cold air and hot air, namely the physical properties that the cold air tends to sink and the hot air tends to float. Meanwhile, the arrangement of the first preset angle or the second preset angle is beneficial to avoiding the situation that the angle of the air guide piece deviates to guarantee the position of the air conditioner in a good running state due to lack of relevant knowledge of the air conditioner in the process of automatically adjusting the air guide piece by a user, so that the comfort of the air conditioner is guaranteed.
In a second embodiment of the present invention, as shown in fig. 4, the step of controlling the longitudinal wind guide of the air conditioner to directly rotate to the second preset angle includes:
step S410, acquiring the current operation mode of the air conditioner;
step S420, when the operation mode is a refrigeration mode, controlling a longitudinal air guide of the air conditioner to rotate upwards so as to supply air upwards;
and step S430, when the operation mode is the heating mode, controlling the longitudinal air guide of the air conditioner to rotate downwards so as to supply air downwards.
In this embodiment, the air blowing direction of the longitudinal air guide is determined by combining physical properties of the cold air or the hot air. When the air conditioner is in a cooling mode, as shown in fig. 5, the longitudinal air guide member is controlled to directly rotate upwards, so that the sent cold air flows upwards, and the cold air sinks under the action of gravity due to higher density of the cold air, so that the indoor temperature is uniform, and meanwhile, the air supply is prevented from directly blowing a human body. When the air conditioner is in a heating mode, as shown in fig. 6, the longitudinal air guide member is controlled to directly rotate downwards, so that the sent hot air flows downwards, and the hot air floats upwards under the action of buoyancy because the density of the hot air is low, so that the indoor temperature is uniform, and meanwhile, the air supply is prevented from directly blowing a human body.
In the third embodiment of the present invention, as shown in fig. 7, after step S410, the air conditioner control method further includes the steps of:
step S440, when the operation mode is a refrigeration mode, increasing the air supply speed of the air conditioner;
and S450, reducing the air supply speed of the air conditioner when the operation mode is the heating mode.
In this embodiment, when the air supply direction of the air conditioner is controlled, the air supply speed of the air conditioner is adjusted to reduce the wind sensation, avoid the air supply direct blowing user and improve the comfort of the air conditioner. Specifically, when the air conditioner is in the cooling mode, as shown in fig. 5, since the cool air is sent upward, the air supply distance is increased by increasing the air supply speed of the air conditioner, so as to avoid the user's moving range and prevent the user from directly blowing. When the air conditioner is in the heating mode, as shown in fig. 6, since the hot air is sent downward, the air supply distance is reduced by reducing the air supply speed of the air conditioner to avoid the user's moving range, so as to avoid directly blowing the user.
In the fourth embodiment of the present invention, as shown in fig. 8, step S440 includes:
step S441, when the absolute value of the difference between the indoor temperature and the air supply temperature is greater than or equal to a second preset temperature difference, increasing the air supply speed of the air conditioner to a first preset air speed;
and step S442, when the absolute value of the difference between the indoor temperature and the air supply temperature is smaller than a third preset temperature difference, increasing the air supply speed of the air conditioner to a second preset air speed.
The second preset temperature difference is larger than or equal to the third preset temperature difference, and the first preset wind speed is larger than the second preset wind speed. In the present embodiment, the degree of reducing the air flow speed of the air conditioner is determined according to the magnitude of the absolute value of the difference between the indoor temperature and the air supply temperature. As the absolute value of the difference between the indoor temperature and the supply air temperature increases, the wind sensation that the user may feel increases accordingly, and therefore, the supply air speed of the air conditioner is increased by a large margin, and the supply air distance is increased further, thus being far away from the user's range of motion, to improve the comfort of the air conditioner.
Further, as shown in fig. 9, step S450 includes:
step S451, when the absolute value of the difference between the indoor temperature and the air supply temperature is greater than or equal to a fourth preset temperature difference, reducing the air supply speed of the air conditioner to a third preset air speed;
step S452, when the absolute value of the difference between the indoor temperature and the air supply temperature is smaller than a fifth preset temperature difference, reducing the air supply speed of the air conditioner to a fourth preset air speed;
the fourth preset temperature difference is greater than or equal to the fifth preset temperature difference, and the third preset wind speed is less than the fourth preset wind speed. The degree of reducing the air speed of the air supply of the air conditioner is determined according to the absolute value of the difference between the indoor temperature and the air supply temperature. With the increase of the absolute value of the difference between the indoor temperature and the air supply temperature, the wind sense which can be felt by a user is correspondingly increased, so that the air supply speed of the air conditioner is reduced in a larger range, the wind sense brought by the larger difference between the indoor temperature and the air supply temperature is compensated, and the comfort of the air conditioner is improved.
In the fifth embodiment of the present invention, as shown in fig. 10, after step S450, the air conditioner control method further includes the steps of:
step S461, acquiring the indoor temperature in a first preset time period, and calculating the absolute value of the temperature variation of the indoor temperature in the first preset time period;
step S462, comparing the absolute value of the temperature variation with a sixth preset temperature difference;
and step S463, when the absolute value of the temperature change amount is smaller than the sixth preset temperature difference, generating a prompt signal, or increasing the air supply speed of the air conditioner.
In the present embodiment, since it is considered that the air conditioner cannot effectively heat if the blowing air speed is too low, the change in the indoor temperature is monitored after the blowing air speed of the air conditioner is reduced. The first preset time period is a certain time period after the air supply speed is reduced, and the variation of the indoor temperature in the first preset time period can be obtained by calculating the difference between the highest temperature and the lowest temperature in the first preset time period, or the difference between the highest temperature and the lowest temperature is calculated after the bad point of the temperature-time curve in the first preset time period is removed and smoothed, so that the accuracy of judgment is improved. The ninth preset temperature difference is the temperature variation of the indoor temperature in the first preset time period in the normal heating state of the air conditioner. If the absolute value of the temperature variation is smaller than the sixth preset temperature difference, the fact that the air supply speed of the air conditioner is too low at the moment and normal heating is difficult is indicated, and a user is reminded to process the air supply speed by generating a prompt signal. Or the air speed of the air supply of the air conditioner is directly increased, the heating capacity of the air conditioner is enhanced, the relation between the heating effect of the air conditioner and the reduction of the wind sensation is balanced, and the comfort of the air conditioner is improved as much as possible.
In the sixth embodiment of the present invention, as shown in fig. 11, after step S410, the air conditioner control method further includes the steps of:
step S471, when the operation mode is the refrigeration mode, acquiring a minimum condensation critical wind speed value and a maximum condensation critical wind speed value of the air conditioner according to a first preset angle and a second preset angle;
step S472, acquiring the current air supply speed of the air conditioner;
step S473, judging whether the current air supply speed is greater than or equal to the minimum condensation critical speed and whether the current air supply speed is less than or equal to the maximum condensation critical speed;
if yes, executing step S474, controlling the air conditioner to supply air at the current air supply speed;
if not, executing the step S475, and controlling the air conditioner to supply air at the minimum condensation critical air speed when the current air supply air speed is less than the minimum condensation critical air speed; and when the current air supply speed is greater than the maximum of the condensation critical air speed, controlling the air conditioner to supply air at the maximum of the condensation critical air speed.
When the air conditioner is in a refrigeration mode, when the transverse air guide piece rotates to a first preset angle and the longitudinal air guide piece rotates to a second preset angle, the first preset angle and the second preset angle are always in a more inclined position, so that an effective air supply opening of the air conditioner is correspondingly reduced, and on one hand, when the air supply speed of the air conditioner is low, because the air flow disturbance is small, indoor water vapor with higher temperature meets air supply with lower temperature, the water vapor is easy to condense and liquefy to generate condensation at the narrow air supply opening; on the other hand, when the air supply speed of the air conditioner is high, the refrigerating capacity sent out in unit time is large, and indoor water vapor with high temperature meets air supply with low temperature, and is easy to condense and liquefy to generate condensation, so that the comfort of the air conditioner is influenced. Therefore, in this embodiment, when the air conditioner operates in the cooling mode, the minimum condensation critical wind speed and the maximum condensation critical wind speed of the air conditioner are obtained according to the first preset angle and the second preset angle, and when the air supply wind speed of the air conditioner is within the range defined by the minimum condensation critical wind speed and the maximum condensation critical wind speed, the air conditioner is controlled to supply air at the current air supply wind speed. So as to avoid blowing the human body directly; when the air speed of the air conditioner is out of the range limited by the minimum value of the condensation critical air speed and the maximum value of the condensation critical air speed, when the current air speed is less than the minimum value of the condensation critical air speed, the air conditioner is controlled to supply air at the minimum value of the condensation critical air speed, and when the current air speed is greater than the maximum value of the condensation critical air speed, the air conditioner is controlled to supply air at the maximum value of the condensation critical air speed, so that condensation is avoided.
In the seventh embodiment of the present invention, as shown in fig. 12, after step S300, the air conditioner control method further includes the steps of:
step S510, when the absolute value of the difference between the indoor temperature and the air supply temperature is larger than or equal to a seventh preset temperature difference, reducing the running frequency of a compressor of the air conditioner;
and step S520, when the absolute value of the difference between the indoor temperature and the air supply temperature is smaller than the eighth preset temperature difference, increasing the running frequency of the compressor.
Wherein the seventh preset temperature difference is greater than or equal to the eighth preset temperature difference. Since the user feels the wind sensation related to the difference between the indoor temperature and the supply air temperature, when the absolute value of the difference between the indoor temperature and the supply air temperature is large, the cooling or heating capacity of the air conditioner is reduced by reducing the operating frequency of the compressor to reduce the absolute value of the difference between the indoor temperature and the supply air temperature, thereby reducing the wind sensation of the user. When the absolute value of the difference between the indoor temperature and the air supply temperature is small, the operation frequency of the compressor is increased, and the refrigerating or heating capacity of the air conditioner is enhanced, so that the refrigerating or heating effect of the air conditioner is guaranteed under the condition of small wind sensation. When the absolute value of the difference between the indoor temperature and the air supply temperature is between the seventh preset temperature difference and the eighth preset temperature difference, the operation frequency of the compressor can be selected not to be adjusted so as to avoid the reduction of the service life of the compressor caused by frequently adjusting the operation frequency; of course, the operation frequency of the compressor may be selected to be appropriately adjusted, and a specific adjustment manner may be implemented by appropriately decreasing the cooling or heating capacity of the air conditioner with reference to an increase in the absolute value of the difference between the indoor temperature and the supply air temperature. There is not definite big or small relation between the seventh preset difference in temperature and the first preset difference in temperature, under the normal condition, can set up the seventh preset difference in temperature and be greater than the first preset difference in temperature, that is to say, change the air supply direction in order to reduce the wind sense preferentially through the position that changes vertical wind guide, and under the great circumstances of difference of indoor temperature and air supply temperature, the mode of changing compressor operating frequency reduces the wind sense in addition, in order to reduce the change of the operating frequency of compressor, the life of extension compressor, avoid the air supply to blow directly the user simultaneously, improve the travelling comfort of air conditioner.
In the eighth embodiment of the present invention, as shown in fig. 13, step S520 includes:
step S521, acquiring the current operation mode of the air conditioner;
step S522, when the operation mode is the refrigeration mode, acquiring the condensation critical frequency of the compressor according to the first preset angle and the second preset angle;
step S523, acquiring a target operation frequency of the compressor;
step 524, judging whether the target running frequency is less than the condensation critical frequency;
if yes, executing step S525, and controlling the compressor to operate at the target operation frequency;
if not, step S526 is executed to control the compressor to operate at the condensation critical frequency.
When the air conditioner is in the mode of refrigeration, rotate to first angle of predetermineeing when horizontal wind guide, vertical wind guide rotates when the angle is predetermine to the second, because first angle of predetermineeing and the second angle of predetermineeing often are in more inclined to one side position, consequently, the effective supply-air outlet of air conditioner is corresponding to be reduced, in constrictive supply-air outlet department, the indoor vapor of higher temperature meets with the air supply of lower temperature, easy condensation liquefaction and produce the condensation, influence the travelling comfort of air conditioner. Therefore, in the present embodiment, when the air conditioner is operated in the cooling mode, the condensation critical frequency of the compressor is determined according to the first preset angle and the second preset angle, and when the compressor is operated above the condensation critical frequency, condensation will start to be generated due to the low supply air temperature. In order to avoid the generation of condensation, the upper limit of the operating frequency of the compressor is the condensation critical frequency. The target operation frequency of the compressor can be obtained by combining experimental results or theoretical calculation according to parameters such as indoor temperature, air supply temperature and the like, and the operation frequency of the compressor can also be gradually increased at a preset frequency interval. Before increasing the operating frequency of the compressor, firstly judging whether the target operating frequency to which the compressor is to be increased exceeds the upper limit limited by the condensation critical frequency, and if the target operating frequency is greater than or equal to the condensation critical frequency, controlling the compressor to operate at the condensation critical frequency to avoid the generation of condensation; and if the target operation frequency is less than the condensation critical frequency, controlling the compressor to operate at the target operation frequency so as to reduce wind sensation.

The ninth preset temperature difference is a temperature variation of the indoor temperature in the second preset time period in a normal cooling or heating state of the air conditioner. If the absolute value of the temperature variation is smaller than the ninth preset temperature difference, the fact that the frequency of the air conditioner compressor is too low at the moment is indicated, normal refrigeration or heating is difficult, and a user is reminded to process the air conditioner compressor by generating a prompt signal. Or, the operation frequency of the compressor is directly increased, so that the cooling or heating capacity of the air conditioner is enhanced, the relation between the cooling or heating effect of the air conditioner and the reduction of the wind sensation is balanced, and the comfort of the air conditioner is improved as much as possible.
