Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The invention provides a variable frequency control method and a control device of an air conditioner and the air conditioner, which are described below with reference to the accompanying drawings. Before the embodiments of the present invention are explained in detail, the entire application scenario is described first. The frequency conversion control method, the frequency conversion control device, the electronic equipment and the computer readable storage medium of the air conditioner provided by the embodiment of the invention can be applied to the local air conditioner, can also be applied to a cloud platform in the Internet field, or can be applied to cloud platforms in other kinds of Internet fields, or can also be applied to third-party equipment. The third-party device may include a plurality of different types such as a mobile phone, a tablet computer, a notebook, a vehicle-mounted computer, and other intelligent terminals.
The following description is only given by taking an inverter control method applied to an air conditioner as an example, and it should be understood that the control method of the embodiment of the present invention may also be applied to a cloud platform and a third-party device.
It should be further noted that the inverter control method of the air conditioner provided by the present invention has universality, that is, the method is simultaneously suitable for the air conditioner to perform cooling or heating in a low temperature environment or a high temperature environment, and the cooling of the air conditioner will be described as an example hereinafter without losing generality.
As shown in fig. 1, according to the inverter control method of the air conditioner in the embodiment of the first aspect of the present invention, the air conditioner is connected to a power supply, and the power supply at least includes a solar power supply device. The frequency conversion control method comprises the following steps:
and 300, acquiring the total input power of the power supply to the air conditioner according to the power supply type, and performing frequency conversion adjustment on the air conditioner according to the total input power.
According to the frequency conversion control method of the air conditioner, the specific working process is as follows: in step 100, after the air conditioner is turned on, the solar power supply device supplies power to the air conditioner and inputs corresponding solar input power to the air conditioner, and the controller obtains the current solar input power and the minimum power required by the operation of the air conditioner, where the minimum power refers to the power of the entire air conditioner when the compressor, the fan, and other components all operate at their respective minimum powers, and the minimum power may be pre-stored in the system in advance or obtained through detection.
For step 200, after the controller acquires the solar input power and the minimum power, the controller compares the current solar input power with the minimum power of the air conditioner, and when the controller determines that the solar input power cannot meet the requirement of the air conditioner for running at the minimum power, the controller judges that the air conditioner needs to adopt a hybrid power supply type, so that the air conditioner is simultaneously supplied with power through the solar power supply device and the mains supply; when the controller determines that the solar input power can meet the requirement of the air conditioner for running at the lowest power, the controller judges the power supply type of the air conditioner needing to be supplied with the solar power, so that the air conditioner is supplied with the power only through the solar power supply device.
For step 300, after the power supply of the air conditioner is adjusted according to the specific power supply type, the controller further obtains the total input power of all power supplies to the air conditioner, and performs frequency conversion adjustment on the air conditioner according to the specific size of the total input power, so that the operating frequency of components such as a compressor and the like in the air conditioner is matched with the total input power, the normal operation of the air conditioner is ensured, and the problem of air conditioner failure caused by unstable current and voltage is avoided.
It is understood that the hybrid power supply refers to a type in which the commercial power and the solar power supply device simultaneously supply power to the air conditioner, and the solar power supply refers to a type in which the air conditioner is supplied with power only through the solar power supply device.
In summary, according to the frequency conversion control method of the air conditioner of the embodiment of the invention, the power supply mode of the air conditioner is adjusted based on the solar input power and the minimum power required by the operation of the air conditioner, so that the air conditioner can normally operate, and the purpose of saving energy is achieved by combining the solar power supply, so that the supply of commercial power is reduced on the premise of ensuring the normal operation of the air conditioner, and the green and environment-friendly energy supply mode is achieved by the solar power supply.
Furthermore, the method can also carry out frequency conversion adjustment on the air conditioner based on different power supply modes, so that the operating frequency of components such as a fan, a compressor and the like in the air conditioner can be matched with the total input power, the normal operation of the air conditioner is ensured, and the problem of air conditioner faults caused by unstable current and voltage is avoided.
According to some embodiments of the present invention, the step of determining a first control logic according to the solar input power and the minimum power, and adjusting the power supply type of the air conditioner based on the first control logic specifically includes:
determining that the solar input power is not lower than the lowest power, determining the power supply type of the air conditioner to supply power for solar energy and supplying power through a solar power supply device;
and determining that the solar input power is lower than the minimum power, determining that the power supply type of the air conditioner is hybrid power supply, and supplying power through a solar power supply device and mains supply.
Therefore, when the solar power supply device supplies power to the air conditioner independently, if the solar input power cannot meet the requirement of the air conditioner for running according to the lowest power (namely the solar input power is lower than the lowest power), extra commercial power needs to be introduced to supply power to the air conditioner, and the power supply type of the air conditioner is hybrid power supply, namely the solar power supply device and the commercial power supply power the air conditioner at the same time; if the solar input power can meet the requirement of the air conditioner for operation according to the lowest power (namely the solar input power is greater than or equal to the lowest power), the air conditioner adopts a power supply type of solar power supply, so that the input of commercial power is avoided, the power consumption is reduced, and the air conditioner is green and environment-friendly.
According to some embodiments of the invention, the step of determining the power supply type of the air conditioner as hybrid power supply and supplying power through the solar power supply device and the commercial power supply specifically comprises:
under the hybrid power supply, simultaneously supplying power to the air conditioner through a commercial power and solar power supply device, and acquiring the actual operating power of the air conditioner;
and adjusting the commercial power input power of the commercial power to the air conditioner according to the comparison result between the solar energy input power and the actual operation power.
In this embodiment, after the air conditioner enters the power supply type of hybrid power supply, the controller will adjust the commercial power input power of the commercial power to the air conditioner according to the specific size of the solar power input power of the solar power supply device to the air conditioner, so that the commercial power and the solar power supply device meet the power consumption requirement of the air conditioner.
Specifically, the step of adjusting the commercial power input power of the commercial power to the air conditioner according to the comparison result of the solar energy input power and the actual operation power specifically includes:
and adjusting the mains supply input power according to the difference between the solar energy input power and the actual operation power, so that the sum of the mains supply input power and the solar energy input power is not lower than the actual operation power.
For example, when the actual operating power is the set operating power, the commercial power input power is the set operating power minus the current solar input power; and if the actual operation power is the correction power, the commercial power input power is the correction power minus the current solar input power.
In a specific embodiment of the present invention, the step of determining the type of power supply of the air conditioner as hybrid power supply and supplying power through the solar power supply device and the utility power specifically includes:
under the hybrid power supply, the solar power supply device is controlled to supply power to the air conditioner according to the maximum solar input power, and the commercial power input power is adjusted according to the solar input power and the actual operating power, so that the sum of the commercial power input power and the solar input power is not lower than the actual operating power.
Therefore, the solar power supply device is controlled to supply power to the air conditioner according to the maximum solar input power, the power supply proportion occupied by the mains supply under the hybrid power supply can be reduced as much as possible, so that the power is saved, the waste of redundant energy is avoided, and the air conditioner is more environment-friendly to operate.
According to some embodiments of the present invention, in the step of performing variable frequency regulation on the air conditioner according to the total input power of the power supply to the air conditioner: the power supply comprises a solar power supply device, and the total input power is solar input power; or the power supply comprises a solar power supply device and a mains supply, and the total input power is the sum of the mains supply input power and the solar input power.
It can be understood that, no matter the air conditioner is in the power supply type of solar power supply or in the power supply type of hybrid power supply, there is a possibility that the total external input power is smaller than or greater than the rated power of the air conditioner, so that in the solar power supply or hybrid power supply, if the controller detects that the total input power is smaller than or greater than the rated power of the air conditioner, the controller further performs frequency conversion adjustment on the air conditioner, so that the actual operating power of the air conditioner matches the total input power.
According to some embodiments of the invention, before the step of performing variable frequency regulation on the air conditioner according to the total input power, the variable frequency control method further comprises: and acquiring the rated power of the air conditioner.
The step of carrying out frequency conversion adjustment on the air conditioner according to the total input power specifically comprises the following steps: and determining a second control logic according to the total input power and the rated power, and carrying out variable frequency adjustment on the air conditioner based on the second control logic.
In this way, the operation type of the variable frequency regulation of the air conditioner can be determined by comparing the total input power with the rated power of the air conditioner, and specifically, the controller can perform the frequency increasing up-regulation of the air conditioner or the frequency decreasing down-regulation of the air conditioner according to the comparison result between the total input power and the rated power.
For example, the step of determining a second control logic according to the total input power and the rated power, and performing variable frequency adjustment on the air conditioner based on the second control logic specifically includes:
performing frequency-up regulation on the air conditioner according to the condition that the total input power is higher than the rated power;
and performing frequency reduction adjustment on the air conditioner according to the condition that the total input power is lower than the rated power.
Therefore, the actual operation power of the air conditioner is changed through frequency conversion adjustment or frequency boosting adjustment, so that the actual operation power of the air conditioner can be matched with the total input power of an external power supply, the stable operation of the air conditioner is ensured, and the problem of air conditioner faults caused by unstable current and voltage is avoided.
According to some embodiments of the present invention, the step of determining a second control logic according to the total input power and the rated power, and performing variable frequency regulation on the air conditioner based on the second control logic specifically includes:
and adjusting the frequency conversion gear of the air conditioner according to the range of the percentage of the total input power relative to the rated power.
In this embodiment, the air conditioner may have two or more frequency conversion stages, each corresponding to a different frequency range. During the operation of the air conditioner, the controller adjusts the air conditioner to a variable frequency gear corresponding to the range in which the percentage of the total input power relative to the rated power is located according to the range in which the percentage is located.
For example, the step of adjusting the variable-frequency gear of the air conditioner according to the range of the percentage of the total input power relative to the rated power includes:
adjusting the air conditioner to a first variable frequency gear according to the fact that the percentage located interval is a first percentage interval;
adjusting the air conditioner to a second variable frequency gear according to the percentage interval as a second percentage interval;
adjusting the air conditioner to a third variable frequency gear according to the percentage interval as a third percentage interval;
adjusting the air conditioner to a fourth variable frequency gear according to the fourth percentage interval;
adjusting the air conditioner to a fifth variable frequency gear according to the fifth percentage interval;
the first percentage interval, the second percentage interval, the third percentage interval, the fourth percentage interval and the fifth percentage interval are sequentially reduced, and the frequencies in the first frequency conversion gear, the second frequency conversion gear, the third frequency conversion gear, the fourth frequency conversion gear and the fifth frequency conversion gear are sequentially reduced.
Further, the first percentage interval is 100% to 110%, the second percentage interval is 90% to 100%, the third percentage interval is 70% to 80%, the fourth percentage interval is 50% to 60%, and the fifth percentage interval is 35% to 45%.
