The following several specific embodiments may be combined with each other, and details of the same or similar concepts or processes may not be repeated in some embodiments. Embodiments of the present application will be described below with reference to the accompanying drawings.
Fig. 3 is a flowchart illustrating a control method of an air conditioner according to an embodiment of the present application. As shown in fig. 3, a method for controlling an air conditioner according to an embodiment of the present application includes:
s101: after the air conditioner runs in a refrigeration mode or a dehumidification mode for a preset time, respectively acquiring a first temperature of an inner coil in a first evaporator and a second temperature of the inner coil in a second evaporator according to a preset time period.
The air conditioner in the control method of the air conditioner provided by the embodiment of the application comprises a first evaporator and a second evaporator, and when the air conditioner operates in a cooling mode or a dehumidification mode and has operated for a preset time period, the current temperatures of respective inner coils of the first evaporator and the second evaporator are respectively obtained according to a preset time period, and the obtained current temperatures of the respective inner coils of the first evaporator and the second evaporator are the first temperature and the second temperature.
For example, temperature sensors may be respectively disposed at the centers or corresponding positions of the respective inner coils of the first evaporator and the second evaporator, and the set temperature sensors may obtain the current temperatures of the respective inner coils according to a preset time period, that is, the first temperature of the inner coil in the first evaporator and the second temperature of the inner coil in the second evaporator. A plurality of temperature sensors may be disposed at corresponding positions of the respective inner coils of the first evaporator and the second evaporator, so as to determine average values of current temperatures acquired by the plurality of temperature sensors disposed in the respective inner coils of the first evaporator and the second evaporator as the first temperature and the second temperature, respectively. The present embodiment is not limited to the arrangement position and the number of the temperature sensors.
The preset time period may be 20 or 30s, or may be set according to some parameters such as specific performance and power consumption of the air conditioner in an actual working condition, which is not limited in this embodiment.
In addition, the embodiment of the application does not limit the specific operation state and working mode of the refrigeration mode or the dehumidification mode of the air conditioner, and all working conditions in the refrigeration mode or the dehumidification mode are the refrigeration mode or the dehumidification mode related to the embodiment of the application. The method comprises the steps that after the air conditioner runs in a refrigeration mode or a dehumidification mode for a preset time, the current temperatures of coils in a first evaporator and a second evaporator are obtained according to a preset time period, wherein the corresponding current temperatures are obtained after the preset time period so as to improve the accuracy of the obtained current temperatures. The preset time period may be 10 minutes, 15 minutes, and the like, for allowing the air conditioner to enter the cooling mode or the dehumidifying mode for a smooth period, which is not limited in this embodiment.
S102: and if the first temperature and the second temperature are determined to meet the preset control conditions, starting a refrigeration optimization mode of the air conditioner so as to adjust the refrigeration flow of the air conditioner according to the first temperature, the second temperature and a preset control strategy.
After the current temperatures of the respective inner coils of the first evaporator and the second evaporator are obtained according to a preset time period, whether the obtained current temperatures meet preset control conditions or not is determined, if the obtained current temperatures meet the preset control conditions, namely, if the obtained current temperatures meet the preset control conditions, a refrigeration optimization mode of the air conditioner is started, so that the refrigeration flow of the air conditioner is adjusted according to the first temperature, the second temperature and a preset control strategy, and the current refrigeration mode or the dehumidification mode of the air conditioner is optimally controlled.
Whether the first temperature and the second temperature meet the preset control condition or not is used for indicating whether the air conditioner starts a refrigeration optimization mode of the air conditioner or not, if yes, the air conditioner is started, otherwise, the air conditioner control method provided by the embodiment of the application is ended if not.
In one possible design, a possible implementation manner of determining that the first temperature and the second temperature satisfy the preset control condition in step S102 is shown in fig. 4. Fig. 4 is a flowchart illustrating another control method of an air conditioner according to an embodiment of the present disclosure. As shown in fig. 4, the present embodiment includes:
s201: the first temperature and the second temperature are compared with a preset temperature.
S202: and if the value of the first temperature higher than the preset temperature is greater than or equal to a first preset threshold value, and the value of the second temperature lower than the preset temperature is less than or equal to a second preset threshold value, determining that the first temperature and the second temperature meet a first preset control condition.
S203: and if the value of the second temperature higher than the preset temperature is greater than or equal to a first preset threshold value, and the value of the first temperature lower than the preset temperature is less than or equal to a second preset threshold value, determining that the first temperature and the second temperature meet a second preset control condition.
The preset control condition comprises a first preset control condition or a second preset control condition.
And comparing the acquired first temperature and the acquired second temperature with a preset temperature respectively, wherein if the value of the first temperature higher than the preset temperature is greater than or equal to a first preset threshold value, and the value of the second temperature lower than the preset temperature is less than or equal to a second preset threshold value, the temperature difference between the first temperature and the second temperature is greater than an initially designed temperature difference, so that the first temperature and the second temperature can be determined to meet a first preset control condition. If the comparison shows that the value of the second temperature higher than the preset temperature is greater than or equal to the first preset threshold value, but the value of the first temperature lower than the preset temperature is less than or equal to the second preset threshold value, it also indicates that the temperature difference between the first temperature and the second temperature exceeds the originally designed temperature difference, and it can be determined that the first temperature and the second temperature satisfy the second preset control condition. If the first temperature and the second temperature are determined to meet the first preset control condition or the second preset control condition, it is indicated that the air outlet temperature difference at the two sides of the air conditioner obviously exists, and the refrigeration optimization mode of the air conditioner needs to be started to reduce the temperature difference between the first temperature and the second temperature.
In particular, assume thatFirst temperature in T1The second temperature is expressed as T2Expressed as the preset temperature TSIn this case, the first preset control condition and the second preset control condition in the above description of the embodiment can be expressed as the following relational expression (1) and relational expression (2), respectively:
T1-Ts≥T0and Ts-T2≤T0 (1)
T2-Ts≥T0And Ts-T1≤T′0 (2)
Wherein, T0Is a first preset threshold value, T'0Is a second preset threshold.
