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, as shown in fig. 1, the control method of the air conditioner including the steps of:
s101, obtaining the outdoor environment temperature T4 and the outdoor heat exchanger temperature T3.
In the embodiment of the invention, a temperature sensor can be arranged outdoors, the outdoor environment temperature T4 can be detected by the temperature sensor in real time, and the air conditioner can acquire the outdoor environment temperature T4 at the current moment from the outdoor temperature sensor in real time. The temperature sensor can be arranged on the outdoor heat exchanger, the temperature sensor can detect the temperature T3 of the outdoor heat exchanger in real time, and the air conditioner can obtain the temperature T3 of the outdoor heat exchanger at the current moment from the temperature sensor of the outdoor heat exchanger in real time.
And S102, adjusting the running frequency of the outdoor unit of the air conditioner according to the outdoor environment temperature T4 and the outdoor heat exchanger temperature T3.
In the embodiment of the present invention, the outdoor environment temperature T4 obtained in step S101 may be compared with the outdoor heat exchanger temperature T3, and if the error between the outdoor environment temperature T4 and the outdoor heat exchanger temperature T3 is within a predetermined error range, the detected outdoor environment temperature T4 is accurate, and the operating frequency of the outdoor unit of the air conditioner may be adjusted according to the detected outdoor environment temperature T4. If the error between the outdoor environment temperature T4 and the outdoor heat exchanger temperature T3 exceeds the predetermined error range, the outdoor unit may be subjected to direct solar radiation, so that a certain error exists in the detected outdoor environment temperature T4, that is, the detected outdoor environment temperature T4 is higher than the actual outdoor environment temperature, the operating frequency of the outdoor unit of the air conditioner can be adjusted according to the detected outdoor heat exchanger temperature T3, so as to compensate for the detection deviation of the outdoor environment temperature T4, which is caused by the direct solar radiation of the outdoor unit of the air conditioner, ensure that the operating frequency of the outdoor unit can correspond to the actual outdoor environment, and ensure the refrigeration effect.
The control method of the air conditioner provided by the embodiment of the invention comprises the following steps of firstly, obtaining the outdoor environment temperature and the outdoor heat exchanger temperature; and then adjusting the running frequency of the outdoor unit of the air conditioner according to the outdoor environment temperature and the temperature of the outdoor heat exchanger. In this embodiment, the operating frequency of the outdoor compressor is determined not only by the outdoor ambient temperature, but by the outdoor ambient temperature and the temperature of the outdoor heat exchanger, so that the detection deviation of the outdoor ambient temperature caused by the direct sunlight of the outdoor unit of the air conditioner can be compensated, the operating frequency of the outdoor unit can be ensured to correspond to the actual outdoor environment, and the refrigeration effect can be ensured
Fig. 2 is a flowchart of a control method of an air conditioner according to another embodiment of the present invention. As shown in fig. 2, based on the embodiment shown in fig. 1, step S102 may specifically include:
s201, obtaining a first candidate operating frequency of the outdoor unit of the air conditioner according to the outdoor ambient temperature T4.
As a possible implementation manner, in an embodiment of the present invention, the step S201 may include: determining an outdoor environment temperature range to which the outdoor environment temperature belongs according to the outdoor environment temperature; and determining a first candidate operating frequency corresponding to the outdoor environment temperature range according to the corresponding relation between the outdoor environment temperature range and the first candidate operating frequency which is stored in advance. Specifically, the outdoor environment temperature may be divided into a plurality of temperature intervals, and then the outdoor environment temperature T4 is compared with the temperature intervals, where the temperature interval where T4 falls is the outdoor environment temperature range to which T4 belongs. For example, the outdoor ambient temperature may be divided into (— ∞, T41), [ T41, T42), [ T42, T43), [ T43, T44), [ T44, T45), [ T45, + ∞) six different temperature intervals, where T41, T42, T43, T44, and T45 are preset temperature values. If the outdoor ambient temperature T4 falls within the (∞, T41) temperature range at this time, the outdoor ambient temperature range to which the outdoor ambient temperature T4 belongs is (∞, T41), i.e., T4 < T41.
Furthermore, a mapping relation between the outdoor environment temperature range and the outdoor unit operation frequency is pre-established and stored in a storage module in the air conditioner. After the outdoor environment temperature range is obtained, the mapping relation can be inquired to obtain a first candidate running frequency of the outdoor unit, which is matched with the obtained outdoor environment temperature range.
And S202, acquiring a second candidate operating frequency of the outdoor unit of the air conditioner according to the temperature T3 of the outdoor heat exchanger.
As a possible implementation manner, in an embodiment of the present invention, the step S202 may include: determining the temperature range of the outdoor heat exchanger to which the temperature of the outdoor heat exchanger belongs according to the temperature of the outdoor heat exchanger; and determining a second candidate operating frequency corresponding to the temperature range of the outdoor heat exchanger according to the pre-stored corresponding relation between the temperature range of the outdoor heat exchanger and the second candidate operating frequency. Specifically, the temperature of the outdoor heat exchanger may be divided into a plurality of temperature intervals, and then the temperature T3 of the outdoor heat exchanger is compared with the temperature intervals, where the temperature interval in which T3 falls is the temperature range of the outdoor heat exchanger to which T3 belongs. For example, the outdoor heat exchanger temperature may be divided into (— ∞, T31), [ T31, T32), [ T32, T33), [ T33, T34), [ T34, T35), [ T35, + ∞) six different temperature intervals, where T31, T32, T33, T34, and T35 are preset different temperature values. If the outdoor heat exchanger temperature T3 falls within the (— ∞, T31) temperature range at this time, the outdoor heat exchanger temperature range to which the outdoor heat exchanger temperature T3 belongs is (— ∞, T31), i.e., T3 < T31.
Furthermore, a mapping relation between the temperature range of the outdoor heat exchanger and the running frequency of the outdoor unit is pre-established and stored in a storage module in the air conditioner. After the temperature range of the temperature of the outdoor heat exchanger is obtained, the mapping relation can be inquired, and a second candidate running frequency of the outdoor unit matched with the obtained temperature range of the outdoor heat exchanger is obtained.
S203, if the first candidate running frequency is inconsistent with the second candidate running frequency, the running frequency is adjusted to be the second candidate running frequency. And if the first candidate running frequency is consistent with the second candidate running frequency, adjusting the running frequency to be the first candidate running frequency.
In the embodiment of the invention, the acquired first candidate running frequency is compared with the acquired second candidate running frequency, if the first candidate running frequency is inconsistent with the second candidate running frequency, the outdoor unit is possibly subjected to direct sunlight, so that the detection of the outdoor environment temperature T4 has deviation, namely the detected outdoor environment temperature T4 is higher than the actual outdoor environment temperature, at the moment, the running frequency of the outdoor unit of the air conditioner needs to be adjusted to be the second candidate running frequency, so that the temperature detection deviation of the outdoor unit of the air conditioner caused by the direct sunlight is avoided, and the running frequency of the outdoor unit is ensured to be corresponding to the actual outdoor environment temperature; if the first candidate operation frequency is consistent with the second candidate operation frequency, it is indicated that the outdoor unit does not detect the outdoor environment temperature T4 under the influence of direct sunlight, and the outdoor environment temperature T4 is accurately detected, and the operation frequency of the outdoor unit of the air conditioner is adjusted to be the first candidate operation frequency.
The steps S201 to S203 in the above embodiment will be described in detail with reference to table 1. Table 1 is a table showing mapping relationships between the outdoor environment temperature range, the outdoor heat exchanger temperature range, and the operation frequency of the outdoor unit of the air conditioner according to an embodiment of the present invention. Wherein Fa (F1-F5) is the maximum operating frequency of the outdoor unit of the air conditioner, and Fa increases and then decreases with the increase of the outdoor environment temperature, for example, F1-F5 increase and then decrease, F1-F3 increase and F3-F5 decrease. As a possible implementation manner, after the outdoor unit is started, the operation frequency is F0, the detected outdoor environment temperature T4 is 19 ℃, the temperature is compared with each outdoor environment temperature range to obtain that the outdoor environment temperature T4 is within the range of T4 < T41, the mapping relation between the outdoor environment temperature range T4 < T41 and the operation frequency of the outdoor unit is queried to obtain that the first candidate operation frequency corresponding to the outdoor environment temperature range is F1; the detected temperature T3 of the outdoor heat exchanger is 40 ℃, the temperature is compared with the temperature ranges of the outdoor heat exchangers to obtain the temperature T3 of the outdoor heat exchanger within the range of T3 to T31, the mapping relation between the temperature range T3 to T31 of the outdoor heat exchanger and the operation frequency of the outdoor unit is inquired, and the second candidate operation frequency corresponding to the temperature range of the outdoor heat exchanger at the moment is F1. At this time, the first candidate operating frequency and the second candidate operating frequency are both F1, which indicates that the outdoor unit does not detect the outdoor environment temperature due to the direct sunlight and detects the outdoor environment temperature accurately, so that the Fa maximum operating frequency corresponding to the outdoor unit of the air conditioner is F1, and the outdoor unit frequency is changed from the initial frequency F0 to the operating frequency F1. As another possible implementation manner, after the outdoor unit is turned on, the operation frequency F0 is, when the outdoor unit is affected by direct sunlight, still 19 ℃ of the air temperature, but the detected outdoor environment temperature T4 is changed to 28 ℃ under the direct sunlight, the T4 is compared with each outdoor environment temperature range, so as to obtain the outdoor environment temperature T4 within the range of T41 ≤ T4 ≤ T42, the mapping relationship between the outdoor environment temperature range T41 ≤ T4 ≤ T42 and the outdoor unit operation frequency is queried, so as to obtain the first candidate operation frequency F2 corresponding to the outdoor environment temperature range at this time, but because the detected outdoor heat exchanger temperature T3 is still 40 ℃, the temperature is compared with each outdoor heat exchanger temperature range, so as to obtain the outdoor heat exchanger temperature T3 within the range of T3 ≤ T31, the mapping relationship between the outdoor heat exchanger temperature range T3 ≤ T31 and the outdoor unit operation frequency is queried, so as to obtain the second candidate operation frequency F1 corresponding to the outdoor heat exchanger temperature, at this time, since the first candidate operating frequency does not match the second candidate operating frequency, it is determined that there is a deviation in the detection of the outdoor environment temperature T4, that is, the detected outdoor environment temperature T4 is higher than the actual outdoor environment temperature, and therefore, the outdoor unit operating frequency is adjusted to the second candidate operating frequency F1 corresponding to the outdoor heat exchanger temperature range.
