Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the present application, and it is obvious that the described embodiments are some, but not all embodiments of the present application. 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 application.
The terms first, second and the like in the description and in the claims of the present application are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It will be appreciated that the data so used may be interchanged under appropriate circumstances such that embodiments of the application may be practiced in sequences other than those illustrated or described herein, and that the terms "first," "second," and the like are generally used herein in a generic sense and do not limit the number of terms, e.g., the first term can be one or more than one. In addition, "and/or" in the specification and claims means at least one of connected objects, a character "/" generally means that a preceding and succeeding related objects are in an "or" relationship.
The following explains the terms referred to in the embodiments of the present application:
frequency conversion air conditioner: the frequency conversion air conditioner is internally provided with frequency converters, the voltage of daily electricity consumption is 220V, the frequency is 50Hz, the current with the frequency of 50Hz is rectified and filtered to obtain direct current with the voltage of about 310V, and the direct current is inverted to obtain a frequency conversion power supply for controlling the operation of the compressor. The variable frequency power supply can convert the power grid frequency of 50Hz into 30-130 Hz, and the variable frequency air conditioner is an air conditioner using a variable frequency compressor and a fuzzy control technology and can adjust the refrigerating speed according to the change of indoor air temperature. For example, in a room with 15 square meters, the variable frequency air conditioner has the temperature regulating speed 6-10 minutes faster than that of a fixed frequency type air conditioner. After the set temperature is reached, the variable frequency air conditioner can run at low speed with the power of only 10% of the constant frequency air conditioner, so as to adjust the fine loss of the temperature and maintain the constant temperature state. Based on the principle, for the variable frequency air conditioner, whether the air conditioner is in the low power consumption operation state can be determined through the operation power of the compressor of the variable frequency air conditioner.
The air conditioner is used as a large power consumer in daily life of residents in summer and winter, and a large amount of electric energy is consumed every year. In the related art, the power consumption of the air conditioner has been largely reduced by improving the energy efficiency level of the air conditioner and increasing the power utilization rate of the air conditioner using a variable frequency compressor. But in the use process of the air conditioner, the energy consumption of the air conditioner can be further reduced while the use comfort of a user is improved by reasonably controlling the air conditioner, and the aims of energy conservation and emission reduction are favorably fulfilled.
The following describes the air conditioner control method provided in the embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
As shown in fig. 1, an air conditioner control method provided in an embodiment of the present application may include the following steps 101 to 103:
step 101, under the condition that the air conditioner runs in a refrigeration working mode, obtaining environmental parameters of the current environment of the area where the air conditioner is located.
Wherein the environmental parameters include: ambient temperature and ambient humidity.
For example, in order to achieve the best cooling effect when the air conditioner is operated in the cooling operation mode, cooling measures that can make a user more comfortable need to be made according to the ambient temperature and the ambient humidity of the current environment.
It should be noted that, in summer with higher humidity, the sensible temperature of the user is proportional to the ambient humidity at the same temperature, that is, the lower the ambient humidity is, the more comfortable the user feels at the same temperature. Based on this, when the air conditioner refrigerates, the dehumidification and cooling operation can be carried out according to certain priority according to the ambient temperature and the ambient humidity of the current environment.
After the comfort level is promoted in the body of user, also can not set up lower settlement temperature to can save power consumption to a certain extent.
And 102, calculating a first difference value and a second difference value according to the environment parameter.
Wherein the first difference is a difference between the ambient temperature and a set temperature; the second difference is a difference between the ambient humidity and a preset humidity.
For example, the set temperature may be a temperature set by a user on a remote controller of the air conditioner. The preset humidity is a humidity value determined by the somatosensory comfort level of the user in the air conditioner at different humidity.
Illustratively, when the comparison result of the first difference and the second difference is obtained, the main factors influencing the user somatosensory comfort level under the current environment can be reflected to a certain extent. When the first difference is smaller than the second difference, the fact that the environmental humidity is a main factor influencing the somatosensory comfort of the user is shown; when the second difference is smaller than the first difference, the ambient temperature is a main factor influencing the body feeling comfort of the user.
And 103, determining and executing target operation corresponding to the comparison result according to the comparison result of the first difference and the second difference.
Illustratively, the comparison result of the first difference and the second difference may include the following three types:
results 1:
in result 1, the first difference is smaller than the second difference.
Illustratively, the step 103 may include the following steps 103a1 and 103a 2:
step 103a1, controlling the compressor of the air conditioner to operate according to a first preset operation power and controlling the fan of the air conditioner to rotate according to a first preset rotating speed under the condition that the first difference is smaller than the second difference, so as to reduce the environmental humidity of the current environment.
Step 103a2, when the compressor operates according to the first preset operating power and the fan of the air conditioner rotates according to the first preset rotating speed, if the third difference is greater than the fourth difference, controlling the compressor to operate according to the second operating power and controlling the fan to rotate according to the second rotating speed.
Wherein the third difference is a difference between the ambient temperature after the humidity is reduced and the set temperature; the fourth difference is the difference between the environment humidity after the humidity is reduced and the preset humidity; the second running power is the running power corresponding to the set working mode of the air conditioner; the second rotating speed is a rotating speed corresponding to the set wind speed of the air conditioner.
For example, the first preset operation power may be an operation power corresponding to the dehumidification mode. The dehumidification mode is a preset working mode of the air conditioner when the air conditioner leaves a factory, and has corresponding compressor running power and fan rotating speed. Therefore, when dehumidification is needed, the working parameters corresponding to the set initial mode of the air conditioner can be directly called.
For example, when the first difference is smaller than the second difference, it indicates that the ambient humidity is a main factor affecting the user's sensory comfort, and at this time, the priority for reducing the indoor ambient humidity is higher.
For example, as shown in fig. 2, when the air conditioner is in the cooling mode, the temperature and the humidity of the current environment are obtained in real time, and the difference Δ T between the environment temperature and the set temperature and the difference Δ H between the environment humidity and the preset humidity are calculated. And then comparing the delta T with the delta H, and if the delta T is less than the delta H, controlling the air conditioner to firstly dehumidify and then refrigerate.
It should be noted that, when the air conditioner dehumidifies, the ambient temperature may be reduced as well as the ambient humidity of the current environment, so that the ambient temperature and the ambient humidity of the current environment need to be monitored in real time, and the air conditioner is controlled to switch from the dehumidification operation mode to the refrigeration operation mode after the ambient parameters satisfy certain conditions.
Results 2:
in result 2, the above-mentioned first difference is equal to the second difference.
Illustratively, the step 103 may include the following steps 103 b:
103b, under the condition that the first difference value is equal to the second difference value, if the first difference value is smaller than a preset temperature difference threshold value, controlling a compressor of the air conditioner to operate according to first preset operation power, and controlling a fan of the air conditioner to rotate according to a first preset rotating speed so as to reduce the environment humidity of the current environment; otherwise, controlling the compressor to operate according to the second operation power and controlling the fan to rotate according to the second rotating speed.
The second operation power is the operation power corresponding to the set working mode of the air conditioner; the second rotation speed is a rotation speed corresponding to a set wind speed of the air conditioner.
For example, when the first difference is equal to the second difference, it is also necessary to consider whether the difference between the current ambient temperature and the set temperature exceeds a preset temperature difference threshold. When first difference is less than preset difference threshold value, show that ambient humidity is the main factor that influences user's body and feels comfort level, and this moment, it is higher to reduce indoor ambient humidity's priority. When the first difference is larger than or equal to the preset temperature difference threshold value, the ambient temperature is the main factor influencing the user body feeling comfort level, and at the moment, the priority for reducing the indoor ambient temperature is higher.
For example, as shown in fig. 2, when Δ T is equal to Δ H, it is also necessary to determine the magnitude between Δ T and T1 (i.e., the above-mentioned preset temperature difference threshold). When the delta T is less than T1, the environmental humidity is a main factor influencing the somatosensory comfort of a user, and at the moment, the priority for reducing the indoor environmental humidity is higher, and dehumidification is needed first and then refrigeration is needed; when the delta T is larger than or equal to T1, the environment temperature is the main factor influencing the user body feeling comfort level, at the moment, the priority for reducing the indoor environment temperature is high, and refrigeration and dehumidification are needed.
Results 3:
in result 3, the first difference is larger than the second difference.
Illustratively, the step 103 may include the following steps 103c1 and 103c 2:
and 103c1, controlling the compressor of the air conditioner to operate according to a second operation power and controlling the fan of the air conditioner to rotate according to a second rotating speed to reduce the temperature of the current environment under the condition that the first difference is larger than the second difference.
And 103c2, under the conditions that the compressor operates according to the second operating power and the fan rotates according to the second rotating speed, if a fifth difference value is smaller than a sixth difference value, controlling the compressor to operate according to a first preset operating power and controlling the fan to rotate according to a first preset rotating speed so as to reduce the environmental humidity of the current environment.
Wherein the fifth difference is a difference between the reduced ambient temperature and the set temperature; and the sixth difference is the difference between the environment humidity after the temperature is reduced and the preset humidity.
