Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to an air conditioner control method and device based on fuzzy control.
Background
With the continuous popularization of the low-carbon and environment-friendly concept, the variable frequency air conditioner is favored by a plurality of consumers due to energy conservation, high efficiency, environment protection and comfort. The existing fuzzy control method of the variable frequency air conditioner can change the running frequency and the output power of the variable frequency air conditioner only according to the instant operation of a user, but the default state of the user is not the lowest running frequency and the lowest output power when the user starts the variable frequency air conditioner, the user can not set the energy saving of the variable frequency air conditioner according to the energy saving requirement, and the actual test experience can know that the existing air conditioner product is accompanied with the precipitation of condensed water when in the refrigeration operation, and the user can feel drier in the refrigeration mode, so that the situation is caused by excessive dehumidification, the partial dehumidification belongs to unnecessary energy consumption, much electric quantity can be wasted, and the effect of reducing the cost by using the variable frequency air conditioner cannot be achieved.
At present, energy-saving modes used by some air conditioners are fixed modes, and users cannot make proper selection and adjustment according to actual use environments and temperature changes. Due to the difference of the use environment of the variable frequency air conditioner and the set habit of the user, the actual energy efficiency of the variable frequency air conditioner is still different to a certain extent. There is no mode that can better judge the indoor load, further control the running frequency of the compressor and promote the air conditioner to run according to the energy-saving mode of the required refrigerating capacity. Therefore, the energy-saving control mode (achieving the cooling effect but not excessively dehumidifying) of the variable frequency air conditioner has great practical value and market. Through technical retrieval and analysis, the current fuzzy control technology mainly has the following defects:
1. in order to pursue the refrigeration effect, the initial operation frequency under a specific environment is calculated too much, so that excessive dehumidification is caused in the temperature reduction process, the electric quantity is wasted, and the room is too dry, so that the comfort of a human body is influenced;
2. when fuzzy calculation needs high-frequency operation, frequency is finely adjusted mainly according to temperature difference (difference value between room temperature and set temperature) and temperature drop rate, frequency adjustment speed is slow, and due to long temperature drop time, the temperature of the pipe is always at a lower temperature, so that dehumidification capacity is large, and ineffective energy consumption is large;
3. after the target temperature is reached, fuzzy control enters stabilization period control, the frequency runs according to the frequency when the target temperature is reached, and then the frequency is finely adjusted at the stabilization period to slowly reduce the frequency.
Aiming at the problem that fuzzy control of the air conditioner is not intelligent enough in the related technology, an effective solution is not provided at present.

When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.
Example 1
The air conditioner control method based on fuzzy control provided by the invention is explained with reference to the accompanying drawings.
The air conditioner control method based on fuzzy control provided by the invention can be applied to air conditioner equipment, such as: the air conditioner for home, business, and ship, etc. may be implemented by installing an Application (APP) on a terminal device or writing a control program in a master controller, and fig. 1 shows an optional flowchart of the air conditioner control method based on fuzzy control in this embodiment, and as shown in fig. 1, the method may include the following steps:
s102, acquiring air conditioner target set temperature TIs provided withAnd the ambient temperature T outside the air conditionerOuter coverDetermining the initial operating frequency F of the air-conditioning compressorInitial；
Preferably, the air-conditioning target set temperature T is obtainedIs provided withAnd the ambient temperature T outside the air conditionerOuter coverDetermining the initial operating frequency F of the air-conditioning compressorInitialBefore, still include: providing a selection interface for selecting different energy saving modes in response to the triggered operation of starting the energy saving control, wherein the different energy saving modes are correspondingly provided with target set temperatures TIs provided with(ii) a Determining a target set temperature T for control in response to triggered operation of a selected energy saving modeIs provided with。
The air conditioning system is internally provided with a plurality of energy-saving modes (such as energy-saving 1-3 modes), when a user presses an energy-saving key and then enters the selection of the energy-saving 1-3 modes, the corresponding set temperature T is obtained according to the selected modeIs provided withFor example, energy saving 1 is 24 ℃/65%, energy saving 2 is 26 ℃/65%, and energy saving 3 is 28 ℃/60%; preferably, the temperature of each energy-saving mode can be adjusted by a user according to actual requirements.
One of the functions of the above step S102 is to provide an optimized initial frequency. The specific optimization principle is illustrated as follows: at present, the normal initial operation frequency of the air conditioner is unreasonable to calculate, and according to the relation between the room air conditioner and the room heat load, the temperature is slowly reduced when the room air temperature reaches the upper limit of the room heat exchange at the lower outdoor side ambient temperature, the operation frequency of the compressor continuously operates at high frequency, the air outlet temperature is reduced, a large amount of cold energy is used for dehumidifying the room, the latent heat quantity is increased, the effect of cooling the room is not obvious, and the power consumption is large. According to the reverse Carnot cycle principle, under the higher outdoor side ambient temperature, the compressor must improve the condensation temperature of the air conditioner by improving the frequency, and the heat exchange quantity of the outer machine is increased, so that the heat exchange quantity of the indoor side is improved, the room temperature drop rate is improved, the time for reaching the target temperature is reduced, and the power consumption of the air conditioner is reduced. Therefore, the control is performed by using the initial low frequency when the outdoor temperature is low and the initial high frequency when the outdoor temperature is high.

When the control is specific, the indoor environment temperature T can be detected in real timeInner partDetecting outdoor ambient temperature T in real timeOuter coverObtaining the set temperature as TIs provided with. Meanwhile, the energy-saving initial operation frequency F is calculated by combining the detected external environment temperatureInitialAnd the difference value delta T between the indoor environment temperature and the set temperature; then, T can be determinedOuter coverWhether the virtual temperature control condition is met or not, and if the virtual temperature control condition is met, the ambient temperature T in the air conditionerInner partAnd a target set temperature TIs provided withIs taken as the virtual temperature difference tVirtual temperature difference(determined by the refrigeration system, obtained by temperature drop experiments, tVirtual temperature differencePreferably 6-8 ℃, and the value is generally the best 8 ℃), otherwise the ambient temperature T in the air conditionerInner partAnd a target set temperature TIs provided withThe temperature difference is the ambient temperature T in the air conditionerInner partAnd a target set temperature TIs provided withThe difference of (D) is recorded as tFuzzy temperature difference(tFuzzy temperature difference＝TInner part-TIs provided with). After the determination, adjusting the initial operating frequency F of the air conditioner compressorInitial。
In step S106, a virtual temperature difference stage is added. The virtual temperature difference platform aims to enable the frequency adjustment to reach the target frequency more quickly, so that the time of high-frequency operation is shortened, and the power consumption is reduced. Under the condition of low outdoor temperature, the initial low frequency is adopted, and at the moment, the frequency is easily increased to the target frequency without passing through a virtual temperature difference platform. However, when the temperature is high outdoors and high in temperature, the virtual temperature difference platform is required to be added when the initial high frequency is adopted, so that the frequency adjustment is quickly increased to the target frequency, the time for adjusting the frequency is shortened, the room temperature is reduced more quickly, the condition that the temperature of the pipe is in low-temperature dehumidification for a long time is reduced, and the dehumidification capacity is reduced.
In the above preferred embodiment, the initial frequency of the air conditioner compressor is determined according to the target set temperature of the air conditioner and the external environment temperature of the air conditioner, when the air conditioner is controlled, the virtual temperature difference platform is added in combination with the outdoor environment temperature, and when the external environment temperature of the air conditioner satisfies the virtual temperature control condition, the virtual temperature difference value is used as the temperature difference between the internal environment temperature of the air conditioner and the target set temperature, so as to adjust the initial frequency of the compressor and control the output of the air conditioner. The control mode combines the control of the air conditioner with the ambient temperature in the air conditioner, the ambient temperature outside the air conditioner and the target set temperature to determine and estimate the air conditioner load, so that the frequency of the air conditioner compressor is dynamically adjusted, the problem of insufficient intellectualization of fuzzy control of the air conditioner in the prior art is effectively solved, and the intelligent control of the air conditioner is improved.
In an alternative embodiment, the initial operating frequency F of the air conditioner compressor is adjustedInitialThe method can be realized by adopting the following scheme: calculating the ambient temperature T in the air conditioner in unit timeInner partThe rate of temperature change of; according to the determined ambient temperature T in the air conditionerInner partAnd a target set temperature TIs provided withTemperature difference of (1), ambient temperature T in air conditioner per unit timeInner partThe temperature change rate enters an air conditioner fuzzy control table, and the frequency increment delta F of the air conditioner compressor is calculated; according to the initial operating frequency F of the air-conditioning compressorInitialCalculating the target operation frequency F of the air-conditioning compressor by using the frequency increment delta F of the air-conditioning compressor1Wherein F is1＝FInitial+. DELTA.F; adjusting the operating frequency of the air-conditioning compressor to a target operating frequency F1。
In another optional implementation mode of the invention, the scheme is further optimized to provide the operation frequency in the stable period, so that the intelligent control of the air conditioner is further improved. In concrete implementation, the operation frequency of the air conditioner compressor is adjusted to the target operation frequency F1Then, the method further comprises the following steps: acquiring and judging ambient temperature T in air conditioner in real timeInner partWhether or not to drop to threshold temperature T in stationary phaseStabilizationPreferably, the threshold temperature T of the stationary phaseStabilizationMay be stabilized 1 ℃ above the target, i.e.TStabilization＝TIs provided with+1 ℃ the present invention is not limited thereto, and may be adjusted according to the actual circumstances, for example, 1.5 ℃ or 2 ℃ higher than the target stability; if the ambient temperature T in the air conditionerInner partDecrease to threshold temperature T in stationary phaseStabilizationDetermining the ambient temperature T of the air conditioner from the initial detectionInner partDown to the threshold temperature T of the stationary phaseStabilizationRate of temperature drop of(ii) a Determining the heat load of a room where the air conditioner is located according to the temperature drop rate, and determining the operating frequency f of an air conditioner compressor in a stable period; and adjusting the running frequency of the air conditioner compressor to the running frequency f. Preferably, when the air conditioner compressor operation frequency is adjusted to the operation frequency f, the air conditioner compressor operation frequency is controlled to be decreased to the operation frequency f at a preset frequency decreasing rate, for example, at a frequency decreasing rate of 1 Hz/s. The present invention is not limited to this, and can be adjusted according to the actual situation, for example, the down-conversion speed of 1.5Hz/s, the down-conversion speed of 2 Hz/s.
In the above preferred embodiment, a frequency control scheme in the stabilization period is provided, the heat load of the room is estimated by the temperature drop rate of 1 ℃ which is finally close to the target temperature and humidity, and when the room temperature reaches the target temperature and humidity, the frequency is reduced to the target frequency which can meet the heat load of the room at the fixed frequency reduction speed (1 Hz/s). Further providing intelligence in control.
In addition, after controlling the operation frequency of the air conditioner compressor to drop to the operation frequency f at the preset frequency reduction frequency, the method further comprises the following steps: after the running time of the air conditioner compressor is adjusted to the running frequency fThe running time meets a first preset time threshold (such as 10min), detecting the ambient temperature T in the air conditioner every other second preset time threshold (such as 5min)Inner partThe amount of change in (c); according to the ambient temperature T in the air conditioner detected every second preset time threshold valueInner partAnd controlling the operation of the air conditioner compressor. Wherein, the temperature T of the environment in the air conditioner is detected according to the threshold value every second preset timeInner partControlling the operation of the air conditioner compressor, including: the ambient temperature T in the air conditioner detected every second preset time threshold valueInner partAnd a target set temperature T of the air conditionerIs provided with(e.g., 0.6 ℃) for comparison; if the ambient temperature T in the air conditioner is detected every second preset time threshold valueInner partGreater than the target set temperature T of the air conditionerIs provided withAnd when the temperature difference exceeds the preset control temperature difference, controlling the air conditioner to enter air conditioner fuzzy control, and controlling the ambient temperature T in the air conditioner based on the fuzzy controlInner partDropping to the target set temperature T of the air conditionerIs provided with(ii) a Re-determining the operation frequency f of the air conditioner compressor in the stable period and regulating the operation frequency of the air conditioner compressorTo the operating frequency f.
Specifically, for example, the frequency is decreased to f at a frequency decreasing rate of 1Hz/s, the operation is stabilized for 10min, and then the inner loop change condition every 5min is continuously detected, if T isInner ring after 5min-TIs provided withIf the temperature is higher than 0.6 ℃, the room is stabilized to T by reentering the fuzzy controlIs provided withAnd then recalculating the operating frequency of the stable period to operate, otherwise keeping the operating frequency f of the original stable period to operate all the time.
In the above preferred embodiment, a feedback adjustment mechanism is provided, after the frequency control in the stabilization period is performed, the temperature change of the room is detected in real time, when the heat load of the room changes, the temperature of the room changes, and according to the magnitude of the temperature change, the feedback adjustment mechanism is performed to control the frequency of the compressor to enter the fuzzy control again, so as to adjust the temperature to the target temperature.
Through the series of control, energy consumption caused by unnecessary dehumidification and temperature overshoot can be reduced, and the effects of energy conservation and comfort are achieved.
The method described above will be further described in conjunction with fig. 2 and examples to better understand embodiments of the present invention:
the problem of energy consumption of air conditioners is always a difficult problem which is difficult to fundamentally solve, most air conditioners in the market consider that the temperature can be rapidly reduced only by continuously increasing the frequency to achieve the refrigeration effect in order to pursue the refrigeration effect, and the frequency is slowly adjusted after the target temperature of a room is reached, so that unnecessary dehumidification is caused in the temperature reduction process, and temperature overshoot is caused while the temperature range is maintained, which are unnecessary energy consumption. In order to solve the problem, a brand-new control method is determined in the attached drawing 2, and the method comprises the steps of adjusting the initial frequency, adding a virtual temperature difference platform, controlling the frequency control method in the stabilization period, monitoring the room load in time through a feedback adjustment mechanism, and thus achieving the purpose of automatically calculating the room load and adjusting the frequency.
