Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a control method and device of an air conditioner and the air conditioner in an embodiment of the invention with reference to the accompanying drawings.
Fig. 1 is a flowchart of a control method of an air conditioner according to an embodiment of the present invention, and as shown in fig. 1, the control method of the air conditioner includes:
s101, acquiring the outdoor environment temperature and the outdoor environment humidity.
In the embodiment of the invention, the temperature sensor and the humidity sensor can be arranged on the outdoor unit of the air conditioner, the outdoor environment temperature is detected and obtained through the temperature sensor, and the outdoor environment humidity is detected and obtained through the humidity sensor.
And S102, determining the entering conditions of the corresponding defrosting mode according to the outdoor environment temperature and the outdoor environment humidity.
In the embodiment of the present invention, the entry condition of the defrosting mode corresponding to the acquired outdoor environment temperature and the acquired outdoor environment humidity may be determined according to the outdoor environment temperature and the outdoor environment humidity acquired in step S101.
As a possible implementation manner, an environment area where the air conditioner is located may be determined according to the outdoor environment temperature and the outdoor environment humidity acquired in step S101, and then, according to the environment area, the entry condition of the corresponding defrosting mode may be determined. As a possible implementation, the environmental area may include: a high temperature and low humidity region (e.g., the middle east region), a high temperature and high humidity region (e.g., the south china region), a low temperature and high humidity region (e.g., the northern european region, canada), or a low temperature and low humidity region (e.g., the northern chinese region). When the outdoor environment temperature is detected to be high temperature and the outdoor environment humidity is detected to be low humidity, determining that the environment area where the air conditioner is located is a high temperature and low humidity area; when the outdoor environment temperature is detected to be high temperature and the outdoor environment humidity is detected to be high humidity, determining that the environment area where the air conditioner is located is a high temperature and high humidity area; when the outdoor environment temperature is detected to be low and the outdoor environment humidity is detected to be high, determining that the environment area where the air conditioner is located is a low-temperature high-humidity area; and when the outdoor environment temperature is detected to be low temperature and the outdoor environment humidity is detected to be low humidity, determining that the environment area where the air conditioner is located is a low-temperature low-humidity area.
In the high-temperature low-humidity area, because the high temperature and the low humidity are low, the domestic variable frequency air conditioner is not easy to frost when in the heating mode, and therefore, as a feasible implementation mode, the entering conditions of the defrosting mode in the high-temperature low-humidity area can be as follows: after the compressor is operated accumulatively for a preset first set time T1, the middle temperature T3 of the outdoor heat exchanger is less than a preset first temperature threshold T30, and the outdoor ambient temperature T4 is greater than a preset first outdoor ambient temperature threshold T40. Specifically, the first set time T1, the first temperature threshold T30, and the first outdoor environment temperature threshold T40 may be preset, the outdoor unit heat exchanger middle temperature T3 is detected and obtained by a temperature sensor arranged in the middle of the outdoor unit heat exchanger, and the outdoor environment temperature T4 is detected and obtained by a temperature sensor arranged on the outdoor unit of the air conditioner, so that the entering condition of the high-temperature and low-humidity regional defrosting mode is as follows: after the compressor is operated accumulatively for a preset first set time T1, T3 < T30 and T4 > T40. For example, setting T1 at 90 minutes, T30 at-15 ℃, T40 at-22 ℃, the high temperature and low humidity region defrosting mode entry conditions are as follows: after 90 minutes cumulative compressor operation T3 < -15 ℃ and T4 > -22 ℃.
In the high-temperature and high-humidity area, because the humidity is high but the temperature is high, when the household variable frequency air conditioner operates in the heating mode, the air conditioner usually does not frost or frosts more, and therefore, as a feasible implementation manner, the entering conditions of the defrosting mode in the high-temperature and high-humidity area can be as follows: after the compressor is operated for the first set time T1 cumulatively, the temperature T3 of the middle part of the heat exchanger of the outdoor unit is smaller than a first temperature threshold T30, and the outdoor environment temperature T4 is larger than a first outdoor environment temperature threshold T40; or, the outdoor environment temperature T4 is continuously lower than the preset second outdoor environment temperature threshold T41 for a time equal to a second set time T2, and the second set time T2 is greater than the first set time T1; alternatively, the outdoor ambient temperature T4 continues to be lower than the preset third outdoor ambient temperature threshold T42 for a time equal to a third set time T3, the third outdoor ambient temperature threshold T42 is less than the second outdoor ambient temperature threshold T41, and the third set time T3 is less than the first set time T1. Specifically, a first set time T1, a second set time T2, a third set time T3, a first temperature threshold T30, a first outdoor environment temperature threshold T40, a second outdoor environment temperature threshold T41, and a third outdoor environment temperature threshold T42 may be preset, where T2 > T1, T3 < T1, and T42 < T41, the outdoor heat exchanger middle temperature T3 is detected and obtained by a temperature sensor arranged in the outdoor unit heat exchanger middle, and the outdoor environment temperature T4 is detected and obtained by a temperature sensor arranged in the outdoor unit of the air conditioner, so that the high-temperature and high-humidity area defrosting mode entering condition is as follows: after the compressor is operated accumulatively for a preset first set time T1, T3 is less than T30, and T4 is more than T40; alternatively, the duration of T4 < T41 is equal to T2; or the duration of T4 < T42 is equal to T3. For example, setting T1 to 90 minutes, T2 to 120 minutes, T3 to 3 minutes, T30 to-15 ℃, T40 to-22 ℃, T41 to 3 ℃, and T42 to-8 ℃, the high temperature and high humidity region defrosting mode entry conditions are: t3 < -15 ℃ and T4 > -22 ℃ after 90 minutes of cumulative compressor operation; alternatively, the duration of time T4 < 3 ℃ is equal to 120 minutes; alternatively, the duration of T4 < -8 ℃ is equal to 3 minutes.
Since the low-temperature and high-humidity region is low-temperature and high-humidity, the domestic inverter air conditioner is most prone to frosting when operating in the heating mode, and therefore, as a feasible implementation manner, the entering conditions of the defrosting mode of the low-temperature and high-humidity region can be as follows: after the compressor is operated accumulatively for a preset fourth set time T4, the middle temperature T3 of the outdoor heat exchanger is less than a preset second temperature threshold T31, the outdoor environment temperature T4 is greater than a first outdoor environment temperature threshold T40, the fourth set time T4 is less than a first set time T1 and greater than a third set time T3, and the second temperature threshold T31 is greater than a first temperature threshold T30; alternatively, the time that the outdoor ambient temperature T4 continues to be lower than the second outdoor ambient temperature threshold T41 is equal to the second set time T2; alternatively, the outdoor ambient temperature T4 continues to be lower than the third outdoor ambient temperature threshold T42 for a time equal to the third set time T3. Specifically, a second set time T2, a third set time T3, a fourth set time T4, a second temperature threshold T31, a first outdoor environment temperature threshold T40, a second outdoor environment temperature threshold T41, and a third outdoor environment temperature threshold T42 may be preset, where T3 < T4 < T1, and T31 > T30. Detect through the temperature sensor who sets up in outdoor unit heat exchanger middle part and acquire outdoor unit heat exchanger middle part temperature T3, detect through the temperature sensor who sets up on the outdoor machine of air-conditioner and acquire outdoor ambient temperature T4, then the regional mode entering condition of defrosting of low temperature and high humidity is: after the compressor is operated accumulatively at T4, T3 is less than T31, and T4 is more than T40; alternatively, the duration of T4 < T41 is equal to T2; or the duration of T4 < T42 is equal to T3. For example, setting T2 to 120 minutes, T3 to 3 minutes, T4 to 30 minutes, T31 to-1 ℃, T40 to-22 ℃, T41 to 3 ℃, and T42 to-8 ℃, the low-temperature high-humidity region defrosting mode entry conditions are as follows: after 30 minutes of cumulative compressor operation, T3 < -1 ℃ and T4 > -22 ℃; alternatively, the duration of T4 < 3 ℃ is equal to 120 minutes; alternatively, the duration of T4 < -8 ℃ is equal to 3 minutes.
In the low-temperature and low-humidity area, because the humidity is low but the temperature is low, when the household variable frequency air conditioner operates in the heating mode, frosting is not easy to occur, and therefore, as a feasible implementation mode, the entering conditions of the defrosting mode of the low-temperature and low-humidity area can be as follows: after the compressor is operated accumulatively for a preset fifth set time T5, the intermediate temperature T3 of the outdoor heat exchanger is less than a preset third temperature threshold T32, the outdoor ambient temperature T4 is greater than the first outdoor ambient temperature threshold T40, the fifth set time T5 is less than the first set time T1 and greater than the fourth set time T4, and the third temperature threshold T32 is greater than the first temperature threshold T30 and less than the second temperature threshold T31. Specifically, a fifth set time T5, a third temperature threshold T32, and a first outdoor ambient temperature threshold T40 may be preset, where T4 < T5 < T1, and T30 < T32 < T31. Detect through the temperature sensor who sets up in outdoor unit heat exchanger middle part and acquire outdoor unit heat exchanger middle part temperature T3, detect through the temperature sensor who sets up on the outdoor machine of air-conditioner and acquire outdoor ambient temperature T4, then the regional mode of defrosting of low temperature low humidity entering condition is: after T5 time of cumulative operation of the compressor, T3 < T32, and T4 > T40. For example, setting T5 at 60 minutes, T32 at-5 ℃, T40 at-22 ℃, the low-temperature and low-humidity region defrosting mode entering conditions are as follows: t3 < -5 ℃ and T4 > -22 ℃ after 60 minutes of cumulative compressor operation.
And S103, performing defrosting control on the air conditioner according to the determined entering condition of the defrosting mode.
In the embodiment of the invention, when the temperature of the middle part of the heat exchanger of the outdoor unit of the air conditioner and the outdoor environment temperature meet the entry condition of the defrosting mode determined in the step S102, the air conditioner is controlled to enter the defrosting mode, and the defrosting control is carried out on the air conditioner by adopting the control logics of various different defrosting large conditions, so that the defrosting function of the same air conditioner can be commonly used in different environment areas, and the comfort of a user for using the heating function of the air conditioner is improved.
