In the related art, in the heating process of the existing air conditioner, a high windshield switches a low windshield, most of control logics are controlled by reducing frequency and sacrificing heating capacity, and after a user starts a heating mode, when the windshield is switched, besides a strong windshield, other running windshields only have one limiting frequency in the whole temperature region of the indoor environment temperature, so that the indoor temperature is slowly increased, and the user experience comfort level is reduced. For example, in the indoor low temperature region, the temperature is low in the air-conditioner, and the air-out temperature is low, and the high pressure does not exceed the risk of evaporimeter high temperature protection, because the user switches the windscreen, carries out frequency limitation and leads to heating to experience and feels poor. If in the indoor high temperature interval, the temperature is high in the air conditioner, and the air-out temperature is high, and the risk that high pressure exceeds the high temperature protection of the evaporator is great, because the user switches the windscreen, the fast decline of wind speed leads to the rapid rise of air conditioner indoor unit coil pipe temperature, exceeds the high temperature protection temperature of the evaporator and shuts down.
Based on the above situation, an embodiment of the present invention provides a frequency control method of a compressor, a controller, an air conditioner, and a computer-readable storage medium, where the frequency control method of the compressor includes, but is not limited to, the following steps:
under the heating condition, a target operation windshield is determined according to a windshield instruction input by a user, a target frequency-reducing coefficient is obtained according to the indoor environment temperature and the target operation windshield, the initial operation frequency is determined according to the outdoor environment temperature, and the initial operation frequency of the compressor is subjected to frequency reduction according to the target frequency-reducing coefficient so as to obtain the target operation frequency of the compressor.
According to the technical scheme of the embodiment of the invention, the embodiment of the invention can control the running frequency of the compressor according to the combination of the indoor environment temperature and the target running windshield, and avoids the condition that the running frequency of the compressor is directly changed due to the switching of the windshield.
The embodiments of the present invention will be further explained with reference to the drawings.
As shown in fig. 1, fig. 1 is a schematic diagram of a system architecture platform for performing a frequency control method of a compressor according to an embodiment of the present invention.
The system architecture platform 1000 of the present invention includes one or more processors 1001 and a memory 1002, and fig. 1 illustrates one processor 1001 and one memory 1002 as an example.
The processor 1001 and the memory 1002 may be connected by a bus or other means, such as the bus shown in fig. 1.
The memory 1002, which is a non-transitory computer-readable storage medium, may be used to store non-transitory software programs as well as non-transitory computer-executable programs. Further, the memory 1002 may include high-speed random access memory, and may also include non-transitory memory, such as at least one magnetic disk storage device, flash memory device, or other non-transitory solid state storage device. In some embodiments, memory 1002 optionally includes memory 1002 located remotely from processor 1001, which may be connected to system architecture platform 1000 via a network. Examples of such networks include, but are not limited to, the internet, intranets, local area networks, mobile communication networks, and combinations thereof.
Those skilled in the art will appreciate that the device architecture shown in FIG. 1 does not constitute a limitation of system architecture platform 1000, and may include more or fewer components than those shown, or some components in combination, or a different arrangement of components.
In the system architecture platform 1000 shown in fig. 1, the processor 1001 may be configured to call a frequency control program of the compressor stored in the memory 1002, so as to implement a frequency control method of the compressor.
Based on the hardware structure of the system architecture platform 1000, various embodiments of the air conditioner of the present invention are proposed.
Specifically, the air conditioner according to the embodiment of the present invention includes, but is not limited to, an indoor unit and an outdoor unit, wherein the indoor unit is provided with a controller and an evaporator, the outdoor unit is provided with a compressor, and the controller may include a processor 1001 and a memory 1002 as shown in fig. 1.
Various embodiments of the frequency control method of the compressor of the present invention are proposed based on the above-described module hardware structure of the air conditioner.
As shown in fig. 2, fig. 2 is a flowchart of a frequency control method of a compressor according to an embodiment of the present invention. The method for controlling the frequency of the compressor according to the embodiment of the present invention includes, but is not limited to, step S100, step S200, step S300, and step S400.
Step S100, under the heating condition, acquiring a windshield instruction input by a user, and determining a target operation windshield according to the windshield instruction;
step S200, acquiring outdoor environment temperature, and determining initial operation frequency according to the outdoor environment temperature;
step S300, acquiring indoor environment temperature, and obtaining a target frequency reduction coefficient according to the indoor environment temperature and a target operation windshield;
and step S400, determining a target operation frequency according to the initial operation frequency and the target frequency reduction coefficient.
Specifically, under the heating condition, the air conditioner receives a windshield instruction input by a user, determines a target operation windshield according to the windshield instruction, determines a target frequency-reducing coefficient according to the target operation windshield and the indoor environment temperature, and reduces the frequency of the initial operation frequency according to the target frequency-reducing coefficient to obtain the target operation frequency of the compressor. The embodiment of the invention introduces the indoor environment temperature as a limiting condition in order to realize that the running frequency of the compressor can not influence the heating effect and the temperature of the coil pipe of the indoor unit. When the indoor environment temperature is low, even if the target running windshield is a low windshield, the target frequency reduction coefficient can be very low, namely, the initial running frequency is not subjected to frequency reduction, or the frequency reduction degree is small, so that the compressor can run at a high running frequency when the target running windshield is low but the indoor environment temperature is low, and the heating effect is not influenced. Under the condition with the windscreen, indoor ambient temperature is higher, and the range that the frequency descends is bigger, and target frequency reduction coefficient can increase promptly to even make the same target operation windscreen, the compressor is greater at the degree of falling the frequency of indoor ambient temperature time initial operating frequency, guarantees when indoor ambient temperature is high, reduces the influence to indoor set coil pipe temperature, improves the reliability of air conditioner operation.
It should be noted that the target frequency-reducing coefficient may be determined by looking up a table, that is, the corresponding target frequency-reducing coefficient may be found in the table according to the target operating windshield and the indoor ambient temperature.
It is understood that the target down-conversion coefficient in the table represents a down-conversion degree, which may be a specific down-conversion value or a down-conversion percentage, and the embodiment of the present invention is not limited in particular.
It is understood that the initial operating frequency in step S200 may be determined by:
acquiring outdoor environment temperature, and determining an operation frequency interval corresponding to the outdoor environment temperature according to the outdoor environment temperature;
and determining an initial operating frequency according to the operating frequency interval.
In the heating condition, in order to ensure the heating effect, the initial operating frequency of the compressor needs to consider the outdoor environment temperature, the current operating frequency interval of the air conditioner can be judged according to the outdoor environment temperature, and the frequency of the outdoor environment temperature T4 interval is divided according to the outdoor environment temperature. Temperature T4: the maximum operation F1 gear in the A-B interval, the maximum operation F2 gear in the C-D interval, the maximum operation F3 gear in the E-F interval, the maximum operation F4 gear in the G-H interval, the maximum operation F5 gear in the I-J interval, and the maximum operation F6 gear in the K-L interval, for example: the temperature of the A-B interval is T4 and is 24-27 ℃. The temperature interval is decreased in sequence, and the frequency is gradually increased from F1 to F6.
It is understood that the initial operating frequency in step S200 may also be determined by:
and taking the maximum frequency value in the operation frequency interval as the initial operation frequency.
It is understood that the initial operating frequency in step S200 may also be determined by:
determining a first operating frequency corresponding to the indoor environment temperature according to the indoor environment temperature;
and if the first operating frequency is less than the maximum frequency value, taking the first operating frequency as the initial operating frequency.
Under the heating condition, along with the rise of the indoor environment temperature, the requirement of a user on the heating effect is reduced, and the compressor does not need to operate at a high operation frequency, so that the first operation frequency of the compressor under the current indoor environment temperature is obtained according to the indoor environment temperature, and when the first operation frequency is smaller than the maximum frequency value determined according to the outdoor environment temperature, the first operation frequency is used as the initial operation frequency of the compressor, so that the energy consumption of the air conditioner can be reduced, and the user experience is not influenced.
It is understood that the initial operating frequency in step S200 may also be determined by:
determining a second operating frequency corresponding to the target operating windshield according to the target operating windshield;
and if the second operating frequency is less than the first operating frequency, taking the second operating frequency as the initial operating frequency.
The minimum frequency of the maximum frequency value obtained according to the outdoor environment temperature, the first operation frequency obtained according to the indoor environment temperature and the second operation frequency obtained according to the target operation windshield is used as the initial operation frequency, and the aims of further reducing the energy consumption of the air conditioner and saving resources are achieved under the condition that the heating effect of the air conditioner is not influenced.
Referring to fig. 3, the frequency control process in step S300 may be specifically implemented by the following steps:
step S210, acquiring an indoor environment temperature, and determining a temperature interval corresponding to the indoor environment temperature according to the indoor environment temperature, wherein the temperature interval is obtained by performing interval division on a preset temperature range;
and step S220, obtaining a target frequency reduction coefficient according to the temperature interval and the target running windshield.
And interval division is carried out according to the indoor environment temperature interval: a-b is interval 1, c-d is interval 2, e-f is interval 3, g-h is interval 4, i-j is interval 5, such as the interval a-b is 15-18 ℃ (the temperature units referred to below are all centigrade, and will be collectively described by "degree" for simplicity).
Referring to fig. 4, the frequency control process in step S220 may be specifically implemented by the following steps:
step S310, determining a first frequency modulation coefficient according to the temperature interval;
step S320, determining a second frequency modulation coefficient according to the target running windshield;
step S330, a target frequency reduction coefficient is determined according to the first frequency modulation coefficient and the second frequency modulation coefficient.
The method comprises the steps that a first frequency modulation coefficient can be obtained according to a temperature interval corresponding to the indoor environment temperature, the first frequency modulation coefficient can be increased along with the increase of the indoor environment temperature, a second frequency modulation coefficient is determined by a target operation windshield, the second frequency modulation coefficient can be reduced along with the increase of a gear of the target operation windshield, and a target frequency reduction coefficient is determined according to the first frequency modulation coefficient and the second frequency modulation coefficient. For example, the first fm factor is 2 in the temperature range of 15 degrees to 18 degrees, and the first fm factor is 3 in the temperature range of 18 degrees to 21 degrees. When the running windshield is a low windshield, the second frequency modulation coefficient is 4, and when the running windshield is a high windshield, the second frequency modulation coefficient is 2. Therefore, when the temperature range is 15-18 ℃ and the windshield is low, the target frequency-reducing coefficients can be 2, 3 and 4, when the temperature range is 18-21 ℃ and the windshield is low, the target frequency-reducing coefficients can be 3 and 4, the target frequency-reducing coefficients obtained are different according to different temperature ranges even if the target running windshields are the same, and the compressor is correspondingly subjected to frequency reduction according to the target frequency-reducing coefficients, so that the target running frequency is prevented from being directly limited according to the windshields. The influence of the indoor environment temperature on the target operation frequency of the compressor is fully considered, and the heating effect is ensured.
It should be noted that the above-mentioned numerical value represents the degree of frequency modulation, which can be understood as a gear, or the magnitude of the frequency reduction percentage, and is not a specific frequency modulation parameter. For example, a target downconversion factor of 2 represents a 20% reduction based on the initial operating frequency, and as another example, a target downconversion factor of 2 represents a 4Hz reduction based on the initial operating frequency, etc., to name but a few examples.
Referring to fig. 5, the frequency control process in step S330 may be specifically implemented by the following steps:
step S410, if the first frequency modulation coefficient is larger than the second frequency modulation coefficient, the second frequency modulation coefficient is used as a target frequency reduction coefficient;
in step S420, if the first fm coefficient is not greater than the second fm coefficient, the first fm coefficient is used as a target down-conversion coefficient.
The first frequency modulation coefficient is obtained according to the indoor environment temperature, if the first frequency modulation coefficient is not larger than the second frequency modulation coefficient, the indoor environment temperature is in a lower interval at the moment, in this case, the change of a target operation windshield is not considered, the first frequency modulation coefficient is used as a target frequency reduction coefficient, the low operation frequency of the compressor caused by switching the windshield in a low-temperature interval is avoided, and the heating effect is ensured. If the first frequency modulation coefficient is larger than the second frequency modulation coefficient, the indoor environment temperature is in a higher interval, and in this case, the indoor environment temperature is not considered, the initial operation frequency is subjected to frequency reduction directly according to the second frequency modulation coefficient of the target operation windshield as a target frequency reduction coefficient, and the heating effect is not greatly influenced.
The target down-conversion factor determined from the indoor ambient temperature and the target operating windshield can be referred to in table 1, as follows:
