As shown in fig. 1 to 3, the present invention provides a control method for controlling an air conditioner after the air conditioner is turned on to heat a mode, the control method comprising:
S100, after the outdoor temperature is in a first preset range and the indoor temperature is in a second preset range, determining whether the compressor, the outdoor fan and the indoor fan of the air conditioner are all in a stable running state.
The first preset range is generally limited to be between minus 2 degrees and minus 7 degrees, namely, the outdoor temperature is lower, and the heating capacity of the air conditioner evaporation heat exchange system can be limited. The second preset range is determined based on the set temperature (target temperature), i.e., the second preset range represents a temperature range less than the set temperature, and a temperature range less than 25 ℃ is generally defined as the second preset range, i.e., the set temperature at this time is 25 ℃. The outdoor temperature being in the first preset range and the indoor temperature being in the second preset range represents that the air conditioner is still in the heating mode.
The method comprises the steps of determining whether a compressor, an outdoor fan and an indoor fan of an air conditioner are in a stable running state or not, and determining according to the running frequency of the compressor, the rotating speed of the outdoor fan and the rotating speed of the indoor fan.
S300, after the compressor, the outdoor fan and the indoor fan are all in a stable running state, determining whether an outdoor heat exchanger coil of the air conditioner starts frosting.
Generally, when the compressor, the outdoor fan and the indoor fan are all in a stable running state, the heating capacity representing the evaporation heat exchange of the current air conditioner is stable, and cannot provide more heating capacity, if the outdoor heat exchanger coil begins to frost, the heating capacity of the evaporation heat exchange of the air conditioner is weakened, and the judgment is generally carried out by monitoring the temperature change on the outdoor heat exchanger coil.
S500, after determining that the outdoor heat exchanger coil starts to frost, determining whether the temperature rise amplitude of the temperature in the inner chamber in the first unit time is less than or equal to a first threshold value.
The temperature rise range is the difference between the first indoor temperature at the initial time point in the first unit time and the second indoor temperature at the end time point in the first unit time, namely, the temperature rise range=the second indoor temperature-the first indoor temperature, and the heating effect of the air conditioner which does not start auxiliary heating after the outdoor heat exchanger coil begins to frost can be judged through the temperature rise range in the first unit time.
The first unit time can be preset in the controller of the air conditioner in advance, can be set manually through a network, and can be set according to the current environment condition after the controller learns by itself, wherein the air conditioner has an AI self-learning function.
The indoor temperature is generally detected periodically, namely, the temperature rise amplitude of the indoor temperature is obtained once every first unit time, so that auxiliary heating is controlled to be started in time.
And S700, after the temperature rise amplitude is smaller than or equal to a first threshold value, controlling the air conditioner to start auxiliary heating.
The first threshold may be preset in a preset parameter of the air conditioner controller according to an environmental factor, or may be a specific value determined by the controller according to the current environment and the use habit of the user by self learning, and when the temperature rise amplitude is smaller than or equal to the first threshold, the controller determines that the heating effect of the current air conditioner which is not started for auxiliary heating is not ideal or cannot meet the requirement of the user, so that the air conditioner is controlled to start auxiliary heating at the moment so as to ensure the heating effect.
Generally, the first threshold is set to 0, that is, when the indoor temperature is not changed or reduced after the first unit time passes, it is necessary to control the air conditioner to turn on auxiliary heating.
According to the above, it can be understood that, for the case that the indoor temperature is in the first preset range and the indoor temperature is in the second preset range, after the compressor, the outdoor fan and the indoor fan of the air conditioner are all in the stable running state, it is confirmed that the heating amount of the air conditioner depending on the compressor reaches the limit, after the outdoor heat exchanger coil is determined to start frosting, auxiliary heating is started timely according to the change condition of the indoor temperature, and the situation that the air conditioner still has heating amount when auxiliary heating is not started, auxiliary heating is started prematurely, so that electric energy is meaningless loss is avoided.
In some embodiments, the control method further comprises:
s610, when the temperature rise amplitude is determined to be larger than the first threshold value, determining whether the temperature rise rate of the temperature in the inner chamber in the second unit time is smaller than the second threshold value.
The second unit time may be preset in advance in the controller of the air conditioner, or may be set manually through a network, or may be set according to the current environment situation after the controller learns itself, and generally, the temperature rising rate is determined by obtaining the third indoor temperature at the time starting point of the second unit time, the fourth indoor temperature at the time ending point of the second unit time, and the second unit time, that is, the temperature rising rate= (fourth indoor temperature-third indoor temperature)/the second unit time.
Generally, the second unit time is less long than the first unit time. In some examples, the first unit time is a positive integer multiple of the second unit time, and the first unit time and the second unit time are not equal, e.g., the first unit time may be 3 minutes and the second unit time may be 1 minute.
The temperature rising rate can reflect the heating effect of the current air conditioner after the outdoor heat exchanger coil begins to frost, and when the temperature rising rate is smaller than a certain value or is negative, the condition that the current air conditioner does not start auxiliary heating can be determined, and the heating effect is basically zero.
And S620, controlling the air conditioner to start auxiliary heating when the temperature rising rate is smaller than the second threshold value.
The second threshold is generally set to 0, i.e. when the temperature rising rate is 0 or the temperature rising rate is negative, auxiliary heating is turned on. For some special cases, when the rising rate of the indoor temperature is 0 and the indoor temperature has reached the set temperature, auxiliary heating of the air conditioner can be unnecessary to be started, so that electric energy is saved.
It can be understood that when the temperature rising rate is smaller than a certain value (for example, 2 ℃ per minute), although the indoor temperature rising amplitude is still larger than 0 at this time, the user is not satisfied with the temperature rising rate, and at this time, auxiliary heating can be started based on the control method, so that the temperature rising rate is increased, and the indoor temperature reaches the set temperature as soon as possible.
In other examples, the first unit time may be set to a positive integer multiple of the second unit time as described above, and the first unit time and the second unit time are not equal. Here, the first unit time may be divided into a plurality of second unit times that are continuously distributed, and a temperature rise rate of the temperature in the inner chamber of each second unit time may be determined. Furthermore, the change trend of the temperature rising rate of the temperature in the inner chamber in the first unit time can be determined according to the temperature rising rates of the temperatures in the inner chambers in the plurality of second unit time which are continuously distributed, and when the change trend of the temperature rising rate of the temperature in the inner chamber in the first unit time is determined to be gradually reduced, the gradual reduction of the heating performance of the air conditioner is indicated, and the starting of auxiliary heating of the air conditioner can be controlled.
In some embodiments, S100, determining whether the compressor, the outdoor fan, and the indoor fan of the air conditioner are all in a stable operation state includes:
S110, after the air conditioner enters a heating mode for a preset time, determining whether the running frequency of the compressor, the rotating speed of the outdoor fan and the rotating speed of the indoor fan are consistent in at least three continuous third unit time.
The preset time may be time data pre-stored in the controller, or time data determined by the controller according to the environmental condition after self-learning. The air conditioner is made to enter a heating mode to operate for a preset time so as to enable the operation of the air conditioner to be stable, so that the heating quantity of the current air conditioner can be determined to be stable, or the limit of the heating quantity is reached.
The operation frequency of the compressor, the rotation speed of the outdoor fan and the rotation speed of the indoor fan can reflect the heating quantity condition of the air conditioner under the condition that auxiliary heating is not started, and generally, the heating quantity condition of the air conditioner can be determined by monitoring the change condition of three parameters in a certain time.
The third unit time is generally 30 seconds, and may be pre-stored in the controller, or may be self-learned by the controller and then self-determined according to the environmental state.
And S120, after determining that the operation frequency of the compressor, the rotation speed of the outdoor fan and the rotation speed of the indoor fan are consistent for at least three continuous third unit time, determining whether the compressor, the outdoor fan and the indoor fan are in a stable operation state.
Wherein, because there is the error in the mechanical operation, therefore, to judging whether the compressor operating frequency keeps unanimous in three continuous third unit time, can allow the difference between the maximum value and the minimum value of the compressor operating frequency in three continuous third unit time to be in standard frequency error range, then can judge that the compressor is in steady operation state.
Similarly, for judging whether the rotation speeds of the outdoor fans are consistent in three continuous third unit time, the difference between the maximum value and the minimum value of the rotation speeds of the outdoor fans in the three continuous third unit time can be allowed to be in a standard rotation speed error range, and then the outdoor fans can be judged to be in a stable running state.
Similarly, for judging whether the rotation speeds of the indoor fans are consistent in three continuous third unit time, the difference between the maximum value and the minimum value of the rotation speeds of the indoor fans in the three continuous third unit time can be allowed to be in a standard rotation speed error range, and then the indoor fans can be judged to be in a stable running state.
In some embodiments, S110, determining whether the operating frequency of the compressor, the rotational speed of the outdoor fan, and the rotational speed of the indoor fan are all consistent for at least three consecutive third unit times includes:
And obtaining the average running frequency of the compressor in three continuous third unit time, and if the difference value between the running frequency of the compressor in each third unit time and the average running frequency is smaller than the first standard difference value, determining that the running frequency of the compressor is consistent in at least three continuous third unit time.
That is, if the compressor operation frequencies of the compressors in three consecutive third unit times are h1, h2, and h3, respectively, the average operation frequency in the three consecutive third unit times is h0= (h1+h2+h3)/3, the differences q1=h1-h 0, q2=h2-h 0, q3=h3-h 0 between each compressor operation frequency and the average operation frequency are calculated, respectively, and if q1, q2, and q3 are smaller than the first standard difference q0, it is determined that the operation frequencies of the compressors remain consistent for at least three consecutive third unit times.
It is noted that when comparing the difference between the compressor operating frequency and the average operating frequency with the first standard deviation, it is necessary to perform absolute value processing on the difference, i.e., to compare the sizes of only the digital portions.
The first standard deviation value may be data preset in the controller, and may be a real-time value determined by the controller according to the ambient temperature after the controller learns by itself.
Acquiring first average rotating speeds of the outdoor fan in three continuous third unit time, and determining that the rotating speeds of the outdoor fan are at least consistent in three continuous third unit time if the difference value between the rotating speeds of the outdoor fan and the first average rotating speeds in each third unit time is smaller than the second standard difference value.
The method comprises the steps of obtaining the outdoor fan rotating speeds v1, v2 and v3 of the outdoor fan in three continuous third unit time by referring to the judging method of whether the corresponding compressor frequency is in a stable state, wherein the average rotating speed in the three continuous third unit time is v0= (v1+v2+v3)/3, respectively calculating the difference value w1=v1-v0, w2=v2-v0 and w3=v3-v0 of the rotating speed and the average rotating speed of each outdoor fan, and determining that the rotating speeds of the outdoor fan are consistent in at least three continuous third unit time if the w1, the w2 and the w3 are smaller than the second standard difference value w 0.
It should be noted that when the difference between the outdoor fan speed and the average speed is compared with the second standard deviation, the difference needs to be subjected to absolute value processing, that is, only the size of the digital portion is compared.
The second standard deviation value may be data preset in the controller, and may be a real-time value determined by the controller according to the ambient temperature after the controller learns by itself.
And acquiring second average rotating speeds of the indoor fan in three continuous third unit time, and if the difference value between the rotating speed of the outdoor fan in each third unit time and the second average rotating speed is smaller than the third standard difference value, determining that the rotating speeds of the indoor fan are consistent in at least three continuous third unit time.
The method for determining whether the indoor fan is in the steady operation state is consistent with the method for determining the outdoor fan, and a person skilled in the art can understand and implement determining whether the indoor fan is in the steady operation state according to the above description, so that the description is not repeated here.
After the running frequency of the compressor, the rotating speed of the outdoor fan and the rotating speed of the indoor fan are respectively kept consistent in the same three continuous third unit time, the running frequency of the compressor, the rotating speed of the outdoor fan and the rotating speed of the indoor fan are determined to be kept consistent in at least three continuous third unit time.
That is, it is necessary to determine that the operation frequency of the compressor, the rotation speed of the outdoor fan, and the rotation speed of the indoor fan are consistent for at least three consecutive third unit times after determining that the operation frequency of the compressor, the rotation speed of the outdoor fan, and the rotation speed of the indoor fan are consistent for at least three consecutive third unit times, respectively, in the same three consecutive third times.
In some embodiments, S300, determining whether an outdoor heat exchanger coil of an air conditioner begins to frost, comprises:
