It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
According to an embodiment of the present invention, there is provided a control method of an electric appliance. The control method of the electric appliance can be applied to room air conditioners, and can also be applied to room end control of central air conditioners, dehumidifiers, mobile air conditioners and other equipment. The embodiment of the invention utilizes the artificial intelligence technology to control the electrical equipment to adjust the operation parameters, adjusts the operation parameters to the environment and the conditions, meets the requirements of users and simultaneously has the highest energy efficiency, achieves the aim of energy saving, simultaneously accumulates the operation data into the reference value of the electrical equipment, and continuously learns to realize the maximization of energy saving.
The following examples are described taking an example in which the electric appliance is an air conditioner.
Fig. 1 is a schematic flow chart of an embodiment of a control method of an electrical appliance according to the present invention. The control method of the electric appliance may include:
s102, detecting operation parameters of the electric appliance during operation;
the air conditioner operation parameters comprise parameters such as compressor frequency, external fan rotating speed and electronic expansion valve opening degree, and the air conditioner can collect the parameters in operation in real time.
S104, acquiring the operation energy efficiency of the electrical appliance under the operation parameters to obtain a first energy efficiency;
the operating energy efficiency can be calculated by the following formula.
Operating capacity/operating power = operating energy efficiency, wherein operating capacity is a nominal amount of change of the environmental parameter by the electrical appliance per unit time. Such as the cooling capacity and the heating capacity of the air conditioner.
The way to calculate the running capacity includes the following two ways:
the first method comprises the following steps:
optionally, obtaining the operation energy efficiency of the electrical appliance under the operation parameter, and obtaining the first energy efficiency includes: acquiring target data and pre-stored data detected by a sensor, wherein the target data comprises operation data of the electric appliance and environment data of the environment where the electric appliance is located, and the pre-stored data comprises pre-stored data which is associated with the operation parameters; inputting the target data and the pre-stored data into a capability calculation model to generate the operation capability of the electric appliance; and taking the ratio of the operation capacity to the power as the first energy efficiency.
The air conditioner is provided with an indoor side air inlet temperature and humidity sensor, an indoor side air outlet temperature and humidity sensor, indoor environment data (such as air outlet temperature, humidity, air inlet temperature and humidity) and electric appliance operation data (such as a current windshield) detected by the sensors in real time, and air quantity of each air gear stored in a database, and the operation capacity is calculated by adopting an indoor side air inlet and outlet enthalpy difference method, so that the refrigerating/heating capacity is obtained. Wherein, the wind quantity of each wind shield is measured in the development stage of the air conditioner and is stored in a database (the data does not consider the influence of the atmospheric pressure).
And the second method comprises the following steps:
optionally, obtaining the operation energy efficiency of the electrical appliance under the operation parameter, and obtaining the first energy efficiency includes: acquiring environmental data of an environment where the electric appliance is located before operation, the type of the electric appliance and operation parameters of the electric appliance; determining target data of the electric appliance according to the environment data, the type and the operation parameters, wherein the target data comprises operation data of the electric appliance and environment data of the environment where the electric appliance operates; inputting the target data and the pre-stored data into a capability calculation model to generate the operation capability of the electric appliance; and taking the ratio of the operation capacity to the power as the first energy efficiency.
Under the condition that the air conditioner is not provided with the sensor, according to the operating parameter data of multiple working conditions and multiple models, the air outlet temperature, the humidity, the indoor environment temperature, the empirical values of the heat exchanger tube temperature and the stored air quantity of each wind gear in the database are obtained, and the operating capacity is calculated by adopting an indoor air inlet and outlet enthalpy difference method, so that the refrigerating/heating quantity is obtained. Wherein, the wind quantity of each wind shield is measured in the development stage of the air conditioner and is stored in a database (the data does not consider the influence of the atmospheric pressure).
In the embodiment, the difference of secondary parameters such as atmospheric pressure is ignored, because the calculated operation capability is mainly used for comparing the energy efficiency and the capability before and after adjustment, and the comparison result is not influenced by ignoring the parameter difference of atmospheric pressure.
Compared with the two operation methods, the second method can obtain the operation result without additionally arranging a sensor, and the method can be applied to the air conditioner without the sensor to obtain the energy efficiency of the air conditioner.
S106, adjusting the operation parameter to be a first parameter, and acquiring the energy efficiency of the electric appliance operating under the first parameter to obtain a second energy efficiency;
in order to optimize the energy efficiency of the air conditioner during operation, the parameters which have the highest energy efficiency and are suitable for the current working condition are searched by adjusting the operation parameters. Therefore, when the operation parameters are adjusted, whether the air conditioner meets the requirements of the user under the current operation parameters is judged, if the requirements are met, the operation parameters are continuously adjusted to improve the energy efficiency, and if the requirements of the user are not met, the air conditioner is enabled to meet the requirements of the user firstly, and then the operation parameters are continuously adjusted to improve the energy efficiency. That is, adjusting the operating parameter to a first parameter comprises: detecting whether the environmental parameters under the operating parameters meet target conditions; if the environmental parameters meet the target conditions, acquiring the operation capability of the electrical appliance, and adjusting the operation parameters to the first parameters under the condition of keeping the operation capability; if the environmental parameter does not meet the target condition, the operation capacity is increased or maximized to meet the target condition, and the operation parameter is adjusted to the first parameter under the condition of keeping the operation capacity, wherein the operation capacity is the rated amount of change of the environmental parameter caused by the electric appliance in unit time.
The environment parameters comprise the temperature, the humidity and the like of the current environment, the operation parameters comprise the frequency of a compressor, the rotating speed of an external fan and the opening degree of an electronic expansion valve, and when the air conditioner operates under the operation parameters, if the environment parameters can reach target conditions (the target conditions are the temperature and/or the humidity set by a user), the operation parameters are continuously adjusted to be the first parameters. When adjusting the operating parameters, one operating parameter at a time is adjusted. For example, any one of the compressor frequency, the external fan rotation speed, and the opening degree of the electronic expansion valve is adjusted. Adjusting one parameter at a time can avoid the situation that the environmental parameters fluctuate greatly due to the simultaneous adjustment of a plurality of parameters.
If the current operation parameters can not enable the environmental parameters to reach the target conditions, the refrigerating capacity or the heating capacity of the air conditioner is increased, or the air conditioner is enabled to operate in a mode of the maximum refrigerating/heating capacity, the environmental parameters can meet the target conditions as soon as possible, and after the target conditions are met, the operation parameters are adjusted to be the first parameters again. Similarly, when adjusting the operating parameters, one operating parameter is adjusted each time, which is not described in detail.
It should be noted that each adjustment of the operating parameter is based on the last operating parameter, but the operating parameter may be different and the direction of adjustment may also be different. The direction of adjustment is either an increasing parameter or a decreasing parameter. After the adjustment of the operation parameters is finished, after a certain time state is stable (generally several minutes), the adjusted capacity and energy efficiency are calculated again, and comparative analysis is carried out.
S108, comparing the second energy efficiency with the first energy efficiency, and if the second energy efficiency is higher than the first energy efficiency, continuing to adjust the first parameter to be a second parameter; and if the second energy efficiency is lower than the first energy efficiency, adjusting the first parameter to be a third parameter, wherein the adjustment direction of the first parameter to be the second parameter is opposite to the adjustment direction of the first parameter to be the third parameter.
According to the embodiment of the invention, whether the parameters are continuously adjusted is determined by comparing the energy efficiency before and after the parameters are adjusted, the electric appliance is enabled to operate under the optimal energy efficiency in the parameter adjusting process, the automatic energy efficiency adjustment under different working conditions is realized, and the effect of saving the most energy under the condition of meeting the user requirements is achieved.
To avoid wasting energy by repeatedly adjusting the operating parameter, before adjusting the first parameter to be the third parameter, the method further comprises: if the second energy efficiency is lower than the first energy efficiency, judging whether the first parameter is reversely adjusted or not, and if the first parameter is not reversely adjusted, determining that the first parameter is reversely adjusted to be the third parameter; and if the first parameter is adjusted reversely, taking the adjusted first parameter as the optimal operation parameter under the current working condition. Meanwhile, in order to make the adjustment direction and method of parameters (such as environment and operation parameters) more accurate and faster, expert experience stored in a database can be referred to.
And if the operation parameter is adjusted to be the first parameter, calculating that the second energy efficiency is lower than the first energy efficiency, and judging whether the first parameter is adjusted reversely. If the first parameter is increased to a forward adjustment, the first parameter is decreased to a reverse adjustment. If the first parameter is adjusted reversely, the first parameter is the optimal parameter under the current working condition, the target condition can be met, the energy efficiency can be optimized, continuous adjustment is not needed, and the first parameter can be stored to be used as the operation parameter adopted under the same power consumption at the next time. If the first parameter is not adjusted reversely, the first parameter can be continuously adjusted to be the third parameter.
In a case where the second energy efficiency is higher than the first energy efficiency, the method further includes: and storing the first parameter to use the first parameter as a reference parameter for improving energy efficiency.
Fig. 2 is a flow diagram of a preferred version of a method according to an embodiment of the invention. This is explained below with reference to fig. 2.
Step 1, acquiring indoor environment humidity and temperature, acquiring indoor air outlet temperature and humidity, and acquiring the number of indoor windscreens and air deflectors;
and 2, calculating the current capacity and energy efficiency according to the temperature, the humidity, the windshield and the grid number of the air deflectors.
Step 3, adjusting the operation parameters according to the recorded operation parameters under the current working condition or the empirical operation parameter range in the operation database;
step 4, calculating the adjusted capacity and energy efficiency;
step 5, judging whether the energy efficiency is high, if so, continuing to adjust the operation parameters, exploring and optimizing, and returning to the previous step 4; if not, executing the next step 6;
step 6, judging whether the reverse direction is adjusted; if so, the parameter is the optimal operation parameter under the current working condition, and the parameter is stored in a database so as to operate; if not, adjusting the parameters in the opposite direction, searching for optimization, and returning to the step 4.
According to the embodiment, the air conditioner can search the more energy-saving operation parameters by itself, the operation parameters are stored in the database as experience, and the optimal energy efficiency experience parameters are executed under the condition of the same working condition (indoor environment temperature and humidity and outdoor environment temperature and humidity) next time, namely the most energy-saving effect under the condition of meeting the user requirements is realized.
