Fig. 1 is a flow chart illustrating a method for controlling a wind speed of an air conditioner according to the present invention. As shown in fig. 1, a method for controlling wind speed of an air conditioner according to an embodiment of the present invention includes: step 101, acquiring current body sensing temperature based on indoor humidity information and indoor temperature information.
The main body of the method for controlling the wind speed of the air conditioner according to the embodiment of the present invention is a wind speed control device of the air conditioner.
The application scenario of the air speed control method of the air conditioner provided by the embodiment of the invention is that after a user activates the air conditioner body to enter a cooling or heating mode, the temperature information and the humidity information in the space where the air conditioner system is located are fed back in real time by the sensing module, and the automatic air supply mode executed by the air conditioner system in the corresponding mode is adjusted in an adaptive manner.
The sensing module periodically collects temperature information and humidity information in a space where the air conditioning system is located at specified time intervals, and sends the sensing information to the air speed control device of the air conditioner. The working cycle of the sensing module is not particularly limited in the embodiments of the present invention.
Optionally, the sensing module may perform the collection operation in a default duty cycle.
Alternatively, the user may send a cycle change instruction to enable the sensing module to accept and respond to the instruction, and change the working cycle to the cycle indicated by the instruction to perform the collection operation.
Before step 101, a user needs to send an activation command through a transmission medium to activate an operation mode of the air conditioning system, so that an indoor unit in the air conditioning system operates at a default wind speed of the mode, and an outdoor unit operates at a default frequency of the mode.
The operation mode includes, but is not limited to, a heating mode, a cooling mode, a dehumidifying mode, and the like, which is not specifically limited in this embodiment of the present invention.
Optionally, the user may transmit the activation instruction through the control device in a wireless communication manner between the control device and the air conditioning system, so that the air conditioning system initializes the operating mode.
Optionally, the user may send an activation instruction in a voice interaction manner, and the air conditioning system receives the activation instruction and initializes a corresponding working mode after performing voice recognition.
Specifically, in step 101, after the air conditioner starts the working mode, the air speed control device of the air conditioner receives humidity information and temperature information acquired by the sensing module in the current working period, and calculates by using the humidity information and the temperature information to obtain the current sensible temperature.
The embodiment of the invention does not specifically limit the calculation mode of the current sensible temperature.
Preferably, the general formula of sensible temperature published in 1984 by robert stedman can be used for calculation, and the calculation formula is as follows:
AT＝1.07T+0.2e-0.65V-2.7
wherein AT is sensible temperature (unit is), T is air temperature, namely temperature information (unit is), e is water vapor pressure (unit is hectopar), V is wind speed (unit is meter/second), RH is relative humidity, namely humidity information (unit is percent, which represents percentage of ratio of actual water vapor pressure in air to saturated water vapor pressure AT the current air temperature).
It will be appreciated that e and V may both be determined as a constant based on historical experience during actual use of the air conditioning system. It can be seen that the sensible temperature is lower as the relative humidity is higher and the wind speed is higher.
It should be understood that, the number of the humidity sensors and the temperature sensors in the sensing module is not limited in particular in the embodiments of the present invention.
Optionally, a set of humidity sensor and temperature sensor may be included in the sensing module, and the wind speed control device of the air conditioner may acquire humidity data and temperature information currently acquired by the set of sensing module.
Optionally, the sensing modules may include multiple sets of humidity sensors and temperature sensors in one-to-one correspondence, and the wind speed control device of the air conditioner performs addition and averaging by using humidity data collected by the humidity sensors in the sensing modules respectively to acquire humidity information. In a similar way, the temperature data collected by the temperature sensors in each group of sensing modules are added and averaged to obtain temperature information.
And 102, acquiring a somatosensory temperature difference value based on the current somatosensory temperature and the target somatosensory temperature.
The target sensible temperature is a predetermined appropriate temperature sensed by the user.
The target sensible temperature is a target value of sensible temperature sensed by a human body. The embodiment of the invention does not specifically limit the setting of the target sensible temperature.
The target body temperature may be, for example, an empirical value of a suitable temperature for human perception, such as 26 ℃. The target sensible temperature may also be an appropriate temperature that is set individually by a service user of the wind speed control device of the air conditioner.
Specifically, in step 102, the wind speed control device of the air conditioner determines a sensible temperature difference from the current humidity information acquired in step 101 and a preset target sensible temperature.
The embodiment of the invention does not specifically limit the calculation mode of the somatosensory temperature difference.
For example, the sensible temperature difference may be an absolute value of a difference between the current humidity information and the target sensible temperature.
For example, the sensible temperature difference may also be calculated according to different working modes, where the difference is between the current humidity information and the target sensible temperature.
And 103, generating a control instruction to adjust the rotating speed of the indoor unit under the condition that the somatosensory temperature difference value is larger than or equal to a preset threshold value.
It should be noted that the threshold is preset, and the threshold is set with respect to the somatosensory temperature difference.
The preset threshold is used for comparing the somatosensory temperature difference obtained in the step 102, and when the somatosensory temperature difference is closer to the threshold, it is indicated that the current somatosensory temperature is closer to a proper temperature of a human body.
Illustratively, the preset threshold may be a numerical value, for example, the preset threshold is 0.
For example, the preset threshold may also be an interval, which is referenced to a temperature difference that does not cause a significant perceptual change in the human body, for example, the preset threshold is [0,6 ].
Specifically, in step 103, the air speed control device of the air conditioner compares the sensible temperature difference obtained in step 102 with a preset threshold, and the comparison result is divided into two types: the comparison was successful and failed.
If the comparison is successful, the condition that the somatosensory temperature difference is larger than or equal to the preset threshold value indicates that the current somatosensory temperature exceeds or is close to the target somatosensory temperature suitable for the human body, namely the air-conditioning system cannot reach the optimal somatosensory temperature of the user under the action of the current moment, the air-conditioning air speed control device sends a control instruction to the indoor unit.
The indoor unit receives and responds to the control instruction, and adjusts on the basis of the default rotating speed of the current working mode of the air conditioning system, and then the air volume generated by the change of the air speed can enable the temperature sensitivity of the next body to be closer to the target sensible temperature than the current sensible temperature, so that automatic air control is realized in each working mode.
If the comparison fails, the sensible temperature difference is smaller than the preset threshold value, which indicates that the current sensible temperature is lower than the target sensible temperature suitable for the human body, that is, the air conditioning system exceeds the optimal sensible temperature of the user at the current moment, the air speed control device of the air conditioner is not needed to further control the indoor unit, so that the next integral sensible temperature is kept consistent or slightly reduced compared with the current sensible temperature, and the sensible temperature sensed by the user indoors is fused with the ambient temperature and gradually reduced to the optimal sensible temperature.
The traditional wind speed control method only considers the condition of indoor dry bulb temperature. If in the cooling mode, the indoor temperature is not high, but the humidity is very high, the user still feels very uncomfortable at this moment, and rapid cooling is needed. However, the temperature difference between the indoor dry-bulb temperature and the optimal sensible temperature is not large, so that the indoor unit cannot be driven to increase the rotating speed, and the requirements of users cannot be met.
Similarly, if in the heating mode, the indoor temperature is not low, but the humidity is very high, the temperature sensed by the human body is very low, and the user needs to heat quickly, but the temperature difference between the indoor dry bulb temperature detected by the air speed control device of the air conditioner and the optimal temperature sensed by the air speed control device is very small, so that the indoor unit cannot be driven to increase the rotating speed, and the user's requirements cannot be met.
The calculated human body sensing temperature is determined by the indoor temperature and humidity comprehensively, and in a refrigerating mode or a heating mode, due to the fact that the humidity is introduced, when the humidity is very high, the calculated sensing temperature is closer to the real sensing temperature of a user, and an obvious temperature difference exists between the sensing temperature and the optimal sensing temperature, so that the indoor unit can be driven to adjust the rotating speed, and the requirements of the user cannot be met.
According to the embodiment of the invention, based on indoor humidity information and temperature information, the current sensible temperature is calculated, the sensible temperature difference is calculated by combining the target sensible temperature, and a control instruction is sent to the indoor unit by decision-making according to the sensible temperature difference so as to control the rotating speed of the outdoor unit to be adjusted, so that comprehensive analysis according to the environmental humidity and temperature is realized, after more accurate sensible temperature is obtained, adjustment is carried out by utilizing the difference of the sensible temperature, the control precision and efficiency of the wind speed are improved, the requirements of users can be met quickly and accurately, and the user experience is optimized.
On the basis of any one of the above embodiments, after acquiring the somatosensory temperature difference, the method further includes: and generating a shutdown instruction to control the indoor unit to stop running under the condition that the somatosensory temperature difference value is smaller than a preset threshold value.
Specifically, after step 102, if the comparison result between the sensible temperature difference obtained in step 102 and the preset threshold value is a failure in comparison, the air speed control device of the air conditioner transmits a stop instruction to the indoor unit.
The indoor unit receives and responds to the stop instruction, the indoor unit stops running under the current working mode of the air conditioning system, fresh air quantity is not generated any more, and the sensible temperature sensed indoors by a user and the ambient temperature are gradually fused to the optimal sensible temperature.
According to the embodiment of the invention, a shutdown instruction is decided to be sent to the indoor unit based on the somatosensory temperature difference value so as to control the outdoor unit to stop running, so that comprehensive analysis is carried out according to the ambient humidity and the ambient temperature, more accurate somatosensory temperature is obtained, when the somatosensory temperature meets the requirement of the optimal temperature in the current working mode, the rotating speed of the indoor unit is stopped, the current working mode is not strengthened, the control precision and efficiency of the wind speed are improved, the shutdown can be carried out after the requirement of a user is met, the energy efficiency is saved, and the user experience is optimized.
On the basis of any one of the embodiments, when the somatosensory temperature difference value is greater than or equal to the preset threshold value, a control instruction is generated to adjust the rotation speed of the indoor unit, and the method specifically includes: and under the condition that the somatosensory temperature difference value is matched with the target temperature difference interval, generating a target instruction so as to adjust the rotating speed of the indoor unit to a target gear.
And the target temperature difference interval corresponds to the target gears one by one.
Before step 103, at least two continuous target temperature difference intervals need to be divided between the upper limit and the lower limit of the sensible temperature difference value, so as to quantify different sensible temperature difference levels.
Correspondingly, N target gears are correspondingly divided for the rotating speed of the indoor unit according to the set N individual temperature sensing difference levels.
N is an integer greater than or equal to 1, and the target temperature difference interval and the corresponding target gear division are not particularly limited in the embodiment of the present invention.
For example, the wind speed control device of the air conditioner may divide a plurality of target temperature difference sections between the upper limit and the lower limit of the sensible temperature difference on average. And the target gears corresponding to the target temperature difference intervals are sequentially increased by the same rotating speed interval value.
For example, the wind speed control device of the air conditioner can be divided into a plurality of target temperature difference intervals in a customized manner between the upper limit and the lower limit of the sensible temperature difference. Correspondingly, the proportion of the rotating speed corresponding to the target gear in the whole rotating speed interval is the same as the proportion of the target temperature difference interval corresponding to the target gear in the total interval consisting of the upper limit and the lower limit.
Specifically, the air speed control device of the air conditioner compares the calculated sensible temperature difference value with a pre-divided target temperature difference interval.
When the sensible temperature difference is in the nth target temperature difference range, the air speed control device of the air conditioner may generate a target command corresponding to the range and transmit the target command to the indoor unit.
And the indoor unit receives and responds to the target instruction, and adjusts the rotating speed of the indoor unit to the nth target gear after analyzing the instruction.
Wherein N is an integer less than or equal to N. Therefore, when N is closer to N, it is indicated that the current sensible temperature is less than the requirement of the optimal temperature in the current working mode, and the rotating speed of the indoor unit needs to be increased to the corresponding gear, so that the current working mode is strengthened.
According to the embodiment of the invention, under the condition that the control instruction is generated based on decision to adjust the wind speed, the target instruction corresponding to the magnitude of the somatosensory temperature difference is generated by comparing the somatosensory temperature difference with the target temperature difference interval, so that the indoor unit adjusts the rotating speed to the corresponding target gear under the magnitude, the rotating speed of the indoor unit is quantitatively adjusted according to the actual somatosensory temperature difference, the control precision and efficiency of the wind speed are improved, energy efficiency saving is also considered, and user experience is optimized.
On the basis of any of the above embodiments, the target temperature difference interval comprises a first interval, a second interval, a third interval and a fourth interval with increasing temperatures.
The target gears comprise a first gear, a second gear, a third gear and a fourth gear with gradually increased rotating speeds.
It should be noted that, in advance, 4 continuous target temperature difference intervals need to be divided between the upper limit and the lower limit of the sensible temperature difference value, so as to quantify 4 sensible temperature difference levels.
The numerical setting of the 4 target temperature difference intervals in the embodiment of the present invention is not specifically limited.
Preferably, each target temperature difference interval with increasing temperature is a first interval, a second interval, a third interval and a fourth interval in sequence. Wherein the first interval may be [0,2), the second interval may be [2,4), the third interval may be [4,6), and the fourth interval may be [6, 10).
Correspondingly, 4 target gears are correspondingly set for the rotating speed of the indoor unit according to the set 4 individual temperature sensing difference levels.
The numerical setting of the 4 target gears is not particularly limited in the embodiment of the present invention.
Preferably, each target gear with the increasing rotation speed is a first gear, a second gear, a third gear and a fourth gear in sequence. The first gear is a low-wind-speed gear, the corresponding indoor unit has a rotating speed of 500 revolutions per minute (r/min), the second gear is a medium-wind-speed gear, the corresponding indoor unit has a rotating speed of 700r/min, the third gear is a high-wind-speed gear, the corresponding indoor unit has a rotating speed of 1000r/min, the fourth gear is a high-wind-speed gear, and the corresponding indoor unit has a rotating speed at least greater than 1000r/min, for example, 1200 r/min.
Specifically, in step 103, when the sensible temperature difference is within a certain target temperature difference interval, the air speed control device of the air conditioner may generate a target command corresponding to the interval and transmit the target command to the indoor unit.
Optionally, when the target temperature difference interval in which the sensible temperature difference value is located is the first interval, that is, it is stated that the current sensible temperature slightly does not meet the requirement of the optimal temperature in the current working mode, the air speed control device of the air conditioner sends a target instruction to the indoor unit, so that the indoor unit adjusts the rotating speed of the indoor unit to the first gear, and the current working mode is strengthened to the weakest extent.
