Based on the air conditioner, an embodiment of the present invention provides a method for controlling an air conditioner, where an execution main body is a controller, and the method is shown in fig. 2 as a flowchart of the method for controlling an air conditioner, and includes the following steps:
step S202, acquiring indoor dry bulb temperature in high-temperature and high-humidity environmentDegree T Dry ball And a first temperature T of the evaporator coil 1 ；
Specifically, in a high-temperature and high-humidity environment, the controller obtains the dry bulb temperature T through the indoor environment dry bulb temperature sensing unit Dry ball And acquiring a first temperature T of the evaporator coil through a temperature sensor 1 (ii) a It should be noted that here the evaporator coil first temperature T 1 The lowest temperature of the evaporator coil at that time.
Step S204, analyzing the temperature T of the dry bulb Dry ball And a predetermined threshold, and based on the analysis and the first temperature T of the evaporator coil 1 Adjusting the operating parameters of the air conditioner to obtain first target operating parameters;
in practical application, because the human body needs to sense the temperature more strongly than the humidity, the embodiment of the invention preferentially adjusts the temperature in the high-temperature and high-humidity environment. During normal refrigeration, the operation of rapidly lowering the temperature mainly comprises: (1) The running frequency of the compressor is quickly increased to increase the mass flow of the refrigerant and improve the refrigerating capacity of the air conditioner; (2) The rotating speed of the indoor fan is quickly increased so as to increase the air supply quantity of the air conditioner and improve the refrigerating capacity of the air conditioner; (3) The rotating speed of the outdoor fan is rapidly increased to increase the supercooling degree of the condenser of the air conditioner and improve the refrigerating capacity of the air conditioner; (4) Properly increasing the opening of an outdoor machine throttling device (namely an electronic expansion valve) to improve the mass flow of the refrigerant, reduce the superheat degree of the refrigerant in an evaporator and improve the refrigerating capacity of the air conditioner; (5) Adjusting the angle of an air deflector of the indoor unit to the position with the maximum air output so as to increase the air supply quantity of the air conditioner and improve the refrigerating capacity of the air conditioner; (6) The angle of the air sweeping blade of the indoor unit is adjusted to the position with the maximum air output so as to increase the air supply quantity of the air conditioner and improve the refrigerating capacity of the air conditioner.
Therefore, in order to realize temperature adjustment, the operating parameters of the air conditioner include at least one of the following: the operation frequency of the compressor, the rotating speed of the indoor fan, the rotating speed of the outdoor fan, the opening degree of the electronic expansion valve, the angle of the air deflector and the angle of the wind sweeping blade; and by analysing the dry-bulb temperature T Dry ball Obtaining an analysis result in relation to a predetermined threshold, and obtaining the sum of the analysis resultFirst temperature T of evaporator coil 1 Adjusting the operation parameters of the air conditioner to obtain a first target operation parameter, so that the dry bulb temperature T is achieved when the air conditioner operates according to the first target operation parameter Dry ball Adjusted to a temperature range comfortable for the user. It should be noted that the type and the number of the specific operating parameters may be set according to actual situations, and the embodiment of the present invention does not limit the description of the types and the numbers.
In one possible embodiment, the preset threshold includes a first preset threshold, a second preset threshold and a third preset threshold, where the first preset threshold > the second preset threshold > the third preset threshold; the analysis adjustment process includes: (1) Firstly, the temperature T of the dry bulb is judged Dry ball Whether it is greater than or equal to a first preset threshold and, if so, according to a first adjustment mode and a first temperature T of the evaporator coil 1 Adjusting the operating parameters of the air conditioner to obtain first target operating parameters; (2) If dry bulb temperature T Dry ball Is less than a first preset threshold value, and at the moment, the dry bulb temperature T is judged Dry ball Whether the current value is greater than or equal to a second preset threshold value; if so, then according to a second adjustment mode and the evaporator coil first temperature T 1 Adjusting the operating parameters of the air conditioner to obtain first target operating parameters; (3) On the contrary, if the dry bulb temperature T is lower than the normal temperature Dry ball Is less than a second preset threshold value, and at the moment, the dry bulb temperature T is judged Dry ball Whether the threshold value is greater than or equal to a third preset threshold value; if so, then according to a third adjustment mode and the evaporator coil first temperature T 1 And adjusting the operating parameters of the air conditioner to obtain first target operating parameters. Preferably, the first preset threshold is 35 ℃, the second preset threshold is 25 ℃, the third preset threshold is 20 ℃, and the specific first preset threshold, the second preset threshold and the third preset threshold may be set according to actual situations, and only the first preset threshold and the second preset threshold may be set in some scenes, or multiple preset thresholds and the like may be set, for example, the first preset threshold, the second preset threshold and the third preset threshold are set by dividing the 20 ℃ to 35 ℃ into multiple sections, so as to set multiple preset thresholds, which is not limited in the embodiment of the present invention.
Wherein the first, second and third adjustment modes are in mutual operationWhen the parameters are adjusted, the adjustment processes are different, for example, when the compressor frequency in the operation parameters is adjusted, the first adjustment mode is adjusted to the highest frequency, the second adjustment mode is adjusted to 90% of the highest frequency, the third adjustment mode is adjusted to 80% of the highest frequency, when the indoor fan rotating speed is adjusted, the first adjustment mode is adjusted to the highest wind level, the second adjustment mode is adjusted to 90% of the highest wind level, the third adjustment mode is adjusted to 80% of the highest wind level, and the like, namely, each adjustment mode and the evaporator coil first temperature T 1 The adjusted first target operating parameters are different, so that the adjusted first target operating parameters of each mode correspond to the corresponding preset threshold values.
Therefore, by setting different preset thresholds and analyzing the dry bulb temperature T Dry ball In relation to a predetermined threshold value, and according to different analysis results, adopting a corresponding adjustment mode and a first temperature T of the evaporator coil 1 The operation parameters of the air conditioner are adjusted, the stability of temperature adjustment in a high-temperature and high-humidity environment can be ensured, discomfort caused by rapid cooling in an ultra-strong refrigeration mode is avoided, and the comfort level of a user is ensured.
Step S206, in the process of controlling the air conditioner to operate according to the first target operation parameter, acquiring the indoor wet bulb temperature T Wet ball And a second temperature T of the evaporator coil 2 ；
When the air conditioner operates according to the first target operation parameter, the indoor ambient temperature at this time satisfies the temperature range within which the user is comfortable, but if the ambient humidity (relative humidity > 80%) is still very high, heat dissipation from the human body will be suppressed, resulting in the user feeling sultry and reduced comfort. Therefore, the humidity needs to be adjusted, and specifically, the controller obtains the wet bulb temperature T through the indoor environment wet bulb temperature sensing unit Wet ball And acquiring a second temperature T of the evaporator coil by a temperature sensor 1 To adjust the humidity; it should be noted that here the evaporator coil second temperature T 2 The minimum temperature of the temperature adjusted evaporator coil at this time.
