Based on the hardware architecture of the air conditioner based on the air conditioning system control technology, the embodiment of the control method of the air conditioner is provided.
Referring to fig. 2, in a first embodiment, the control method of the air conditioner includes the steps of:
Step S10, determining a temperature control curve according to the temperature difference to be regulated and the temperature reaching time;
In this embodiment, this embodiment proposes an air conditioner variable frequency control scheme based on temperature and a temperature reaching duration. Firstly, determining a temperature control curve according to the temperature difference to be regulated and the temperature reaching time. The temperature difference to be regulated is characterized as the temperature difference between the current temperature detected by the temperature sensor of the air conditioner and the target temperature desired to be reached by the user. The temperature reaching time is characterized in that the air conditioner changes the current temperature to the target temperature in a refrigerating or heating mode, and the air conditioner needs working time, wherein the temperature reaching time is the temperature reaching time expected by a user.
Alternatively, in some embodiments, the temperature reaching duration may be determined by the air conditioner, where the air conditioner determines a thermal load value in the current environment, obtains a target temperature expected to be reached by the user, and predicts the temperature reaching duration for reaching the target temperature according to the thermal load value in the current environment. Specifically, the determination of the thermal load value Q may be obtained according to the formula q=kf (T n-Tw) a, where k is a heat transfer coefficient, F is an air conditioning active area (i.e., an indoor area), T n is an indoor air temperature, T w is an outdoor air temperature, a is a temperature difference correction coefficient, where k, a are known parameters, and T n and T w may be measured according to installation of corresponding temperature sensors, and F may be input by a user or installation of a laser scanning radar on the air conditioner.
Alternatively, in other embodiments, the warm-up period may be entered directly by the user. Specifically, a user inputs expected temperature reaching time through modes such as an APP (application), a remote controller and the like, the APP or the remote controller sends the temperature reaching time to an air conditioner end, and the air conditioner generates a corresponding temperature control curve according to the temperature reaching time.
Optionally, the temperature control curve is determined in various manners, and the obtained curve is different in type based on the difference of the determination manners, and optionally, the curve type can be a straight line, a parabola, a logarithmic curve and the like. Different temperature control curves, which correspond to different control parameters, also differ with respect to the current temperature that should be reached at the moment.
Step S20, determining target control parameters of the air conditioner based on the temperature control curve and the current time point;
In this embodiment, after determining the temperature control curve, the current time point of the air conditioner is obtained, and the target control parameter of the air conditioner is determined based on the temperature control curve and the current time point. The current time point is characterized as a time point between an initial time when the air conditioner starts to operate cooling/heating and the current time. For example, the initial time is 0, and after 5 minutes, the current time point is 5 minutes. The obtained current time point is consistent with the time point of the horizontal axis on the temperature control curve.
Optionally, the air conditioner obtains the coordinate position of the time point corresponding to the current time point on the temperature control curve according to the current time point, and determines the control parameter of the air conditioner at the coordinate position as the target control parameter. When the air conditioner enters the next working period, determining the current time point of the air conditioner again and updating the target control parameters of the air conditioner.
Specifically, in some embodiments, the air conditioner is provided with a working period with a certain duration, the air conditioner is required to ensure that in the working period, the currently detected indoor temperature changes from the initial temperature at the starting time of the period to the sub-target temperature corresponding to the working period, when the next working period is entered, the air conditioner changes from the sub-target temperature as the new initial temperature to another sub-target temperature corresponding to the next working period again, and so on until the air conditioner reaches the target temperature finally expected by the user after the air conditioner has undergone the working time of the air conditioner corresponding to the temperature reaching duration.
It should be noted that, whether the air conditioner reaches the target temperature during the whole temperature reaching period or the sub-target temperature which the air conditioner should reach in each working cycle, the control parameters of the air conditioner are changed.
For example, the air conditioner is set to have a working period of 3min, the working time of the air conditioner is set to be the initial time 0, and when the air conditioner works in the working period of 0-3min, the indoor temperature delta T which is required to be changed is set to be 1 ℃ by the temperature control curve, and the control parameters comprise the frequency of the compressor and the rotating speed of the inner fan. When the air conditioner detects that the heat load in the room changes (for example, when a person in the room enters or external air flows in after the door of the room is opened, etc.) during the working process of the air conditioner, if the air conditioner is still controlled according to the current control parameters, the current temperature in the room cannot be reduced by 1 ℃ when the time point of 3min is reached, and therefore, the compressor frequency and/or the inner fan rotating speed need to be increased. The compressor frequency is increased to 55HZ, and the rotating speed of the inner fan is increased to 1300r/min, so that the refrigerating/heating rate of the air conditioner is increased, and the current room temperature is reduced by 1 ℃ when reaching the time point of 3 min.
It will be understood, of course, that if the heat load in the room during the duty cycle varies too much to exceed the adjustable range of the cooling/heating components of the air conditioner, and the target temperature for the indian song cannot be reached during the duty cycle, the control parameters can be adjusted during the next duty cycle, or the control parameters in all duty cycles can be increased/decreased, so as to realize temperature-oriented parameter control.
And step S30, controlling the air conditioner to operate according to the target control parameters.
In this embodiment, after the target control parameter is determined, the air conditioner is controlled to operate according to the target control. Optionally, the control parameters include a compressor frequency and an internal fan speed, and the air conditioner is controlled by adjusting the compressor frequency and/or the internal fan speed.
In the technical scheme provided by the embodiment, the temperature control curve is determined through the temperature difference to be regulated and the temperature reaching time length, so that the variable frequency control strategy with the temperature as the guide is executed based on the control parameter corresponding to the current time point of the air conditioner on the temperature control curve, and the air conditioner control logic of the self-adaptive heat load is realized.
Referring to fig. 3, in the second embodiment, based on the first embodiment, the step S10 includes:
step S11, a horizontal axis coordinate interval is determined according to the temperature reaching time length, and a vertical axis coordinate interval is determined according to the temperature difference to be regulated;
step S12, determining a curve formulation strategy corresponding to the air conditioner based on the horizontal axis coordinate interval and the vertical axis coordinate interval;
and step S13, formulating the temperature control curve according to the curve formulation strategy.
Optionally, the present embodiment provides a manner how to determine a temperature control curve according to a temperature reaching duration and a temperature difference to be regulated and controlled, in this embodiment, the temperature control curve is formulated by a preset curve formulation strategy, the temperature reaching duration and the temperature difference to be regulated and controlled are used as matching conditions of the curve formulation strategy, a horizontal axis coordinate interval (corresponding to the temperature reaching working time of the air conditioner) is determined by the temperature reaching duration, a vertical axis coordinate interval (corresponding to the indoor initial temperature and the target temperature) is determined by the temperature difference to be regulated and the corresponding curve formulation strategy is matched according to the horizontal axis coordinate interval and the vertical axis coordinate interval, so that a corresponding temperature control curve is formulated according to the strategy.
Referring to fig. 4, fig. 4 is a schematic diagram of a temperature control curve, the vertical axis of the temperature control curve is the temperature, the horizontal axis is the starting time of the air conditioner, the starting time of the air conditioner is taken as the initial time, the temperature in the current environment is 32 ℃, the target temperature set by the user is 26 ℃, the temperature difference Δt to be regulated is-6 ℃, the expected temperature reaching time T of the user is 15min at the moment, the temperature control curve shown in fig. 3 is determined according to Δ T, T, and the temperature control of the air conditioner is performed with the temperature as a guide in the next 15 minutes, so that the temperature detected by the temperature sensor of the air conditioner at the time point is consistent with the temperature on the curve.
In the technical scheme provided by the example, the corresponding curve making strategy is determined through the temperature reaching time and the temperature difference to be regulated, so that the temperature control curve of the air conditioner in the environment is determined according to the corresponding strategy, and further the variable frequency control of the air conditioner with the temperature as the guide is realized.
Referring to fig. 5, in a third embodiment, based on any one of the embodiments, the step S13 includes:
step S131, when the determined curve formulation strategies are more than two, selecting one curve formulation strategy from the curve formulation strategies according to preset rules as a target curve formulation strategy;
And step S132, formulating the temperature control curve according to the target curve formulation strategy.
Optionally, in this embodiment, when the determined curve formulation policy is more than two, the most suitable policy is selected as the target formulation policy of the temperature control curve according to a certain rule.
Wherein, the step S131 includes:
Step S1311, obtaining an energy efficiency ratio corresponding to the temperature control curve formulated by the air conditioner according to each curve formulation strategy during operation, and determining the curve formulation strategy with the highest energy efficiency ratio as the target curve formulation strategy;
Alternatively, the preset rule may be: and selecting the most energy-saving strategy from the plurality of curve formulation strategies as a target strategy. Specifically, the power consumption of the air conditioner is generally related to the speed of temperature change, so that a strategy capable of minimizing the slope of the temperature control curve in each curve formulation strategy is selected as a target control strategy
Or, step S1312, obtaining the operating power corresponding to the temperature control curve formulated by the air conditioner according to each curve formulation strategy during operation, and determining the curve formulation strategy with the minimum operating power as the target curve formulation strategy;
Optionally, the preset rules are similar to those described above, and policy selection is performed from the energy saving perspective. Specifically, when the air conditioner operates according to the temperature control curve established by each curve establishment strategy, the strategy with the smallest product of the corresponding working current and working voltage is selected as the target establishment strategy.
Or, step S1313, obtaining a health value corresponding to the air conditioner when the temperature control curve formulated by each curve formulation policy runs, and determining the curve formulation policy of the health value closest to a preset health value as the target curve formulation policy;
optionally, because the air-conditioning room has strong tightness, indoor air and outdoor air cannot be exchanged, harmful microorganisms such as bacteria and viruses in the indoor air are easy to breed and reproduce, and air quality is easy to be reduced, so that the preset rule can be as follows: and selecting a strategy with the health value closest to the preset health value from a plurality of curve formulation strategies as a target curve formulation strategy.
Exemplary, setting the optimal indoor environment parameters for the health status of the human body is: indoor-outdoor temperature difference Δt=5 ℃; relative humidity rh=40%, corresponding health value at the environmental parameter is 100, and mapping function H1 between the internal and external temperature difference, humidity and health value is established. And then according to the mapping function H1, simulating health values corresponding to environment parameters when the air conditioner operates under different temperature control curves, and selecting one curve closest to the preset health value 100 from the health values corresponding to each curve, wherein the corresponding control strategy is the target control strategy.
Or, in step S1314, a comfort value corresponding to the temperature control curve formulated by the air conditioner according to each curve formulation strategy during operation is obtained, and the curve formulation strategy with the comfort value closest to the preset comfort value is determined as the target curve formulation strategy.
Optionally, in order to ensure the comfort level of the human body when the air conditioner is in operation, the target operation parameter combination may be determined by a comfort value, which is characterized as a quantized value of the comfort level of the human body in the environment under the air conditioner. The preset rules may therefore be: and selecting a strategy with the comfort value closest to the preset comfort value from the plurality of curve formulation strategies as a target curve formulation strategy. Alternatively, the comfort value determination parameter may be determined by the temperature in the environment, the relative humidity, and/or the air outlet speed of the air conditioner.
For example, the temperature T0 of the human body in a relatively comfortable state is set to 24 ℃, the relative humidity RH0 is set to 30%, the air outlet speed V0 is set to 0.2m/s, and the preset comfort value is set to 0, namely the optimal comfort value, at the aforesaid temperature T0, the relative humidity RH0 and the air outlet speed V0, wherein if the temperature is greater than 0, the user feels the heat, and if the temperature is less than 0, the user feels the cold. And establishing a mapping function H2 among the temperature, the relative humidity and the air outlet speed, simulating comfort values corresponding to environment parameters when the air conditioner operates under different temperature control curves according to the mapping function H2, and selecting one curve closest to a preset comfort value 0 in the comfort values corresponding to the curves, wherein a corresponding control strategy is a target control strategy.
In the technical scheme provided by the embodiment, when the control strategies are multiple, the target control strategy is selected based on the energy-saving, health, comfort and other angles, so that the air conditioning requirements of different users are met, and the product use experience of the users is improved.
Referring to fig. 6, in the fourth embodiment, before step S30, based on any embodiment, the method further includes:
step S40, determining whether a heat source exists in a detection area of the temperature measuring module;
Step S50, if the heat source exists, determining a parameter optimization value according to the heat value of the heat source;
The step S30 includes:
Step S31, optimizing control parameters in the target control parameters based on the parameter optimization values to obtain optimized control parameters;
And step S32, controlling the air conditioner to operate according to the optimized control parameters.
Alternatively, in the present embodiment, since the heat load value in the room is changed when the external heat source enters the operation area of the air conditioner, the air conditioner is provided with a temperature measuring module, and the temperature measuring module monitors whether the heat source exists in the detection area. The heat source is characterized by an object with heat larger than a preset heat threshold, such as a common indoor object of a hot pot, a hot water bag, a household appliance running for a long time, and the like.
Alternatively, the detection area may be an active area of an air conditioner, such as an entire room.
Alternatively, the temperature measuring module may be an infrared temperature measuring sensor.
Further, when it is determined that a heat source exists in the detection area, a parameter optimization value of the control parameters of the air conditioner is determined according to the heat value of the heat source, the control parameters in the target control parameters are optimized based on the parameter optimization value, the optimized control parameters are obtained, and finally the air conditioner is controlled to operate according to the optimized control parameters.
Alternatively, the optimization may be a sum. For example, the set control parameters include a compressor frequency, the determined target compressor frequency is 52HZ, and if the parameter optimization value determined according to the heat value is 3, the obtained optimized control parameter is 52+3=55 HZ.
Alternatively, the optimization may be a product, and the set control parameter includes a compressor frequency, where the determined target compressor frequency is 50HZ, and if the parameter optimization value determined according to the heat value is 1.2, the obtained optimized control parameter is 50×1.2=60 HZ.
In the technical scheme provided by the embodiment, the target control parameters are optimized when the heat load of the room changes by introducing the parameter optimization values, so that the air conditioner can still operate according to the corresponding temperature values and time on the temperature control curve even if the heat load of the room changes, the effectiveness of the control logic guided by the temperature is ensured, and the product use experience of a user is improved.
