Air conditioners can be divided into fixed frequency and variable frequency. The fixed frequency air conditioning compressor operates at a substantially fixed frequency, and the ambient temperature is regulated by switching the compressor on and off, but this approach can result in sudden fluctuations in temperature and high energy consumption. In contrast, the variable frequency air conditioner adjusts the operating frequency by changing the power supply frequency of the compressor, thereby achieving a constant temperature, having less temperature fluctuation and saving energy. In variable frequency air conditioners, PFC (Power Factor Correction ) circuits are often used to increase the power factor. When the input voltage is low and the current is high, the power factor is reduced, and the PFC function is started. However, the PFC function in the current air conditioner is only judged once, and is not adjusted again in the operation process, so that the PFC function is very easy to cause the shutdown of the air conditioner when defrosting, and the user experience is affected.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
The embodiment of the invention provides a control method of a PFC circuit in an air conditioner, which is a variable-frequency air conditioner and comprises an electric control board, wherein the PFC circuit is arranged on the electric control board, and the variable-frequency work of the air conditioner can be controlled through the PFC circuit.
As shown in fig. 1, the control method of the PFC circuit in the air conditioner includes the steps of:
step S110: and under the condition that the air conditioner is in a defrosting mode, acquiring the first voltage of the air conditioner in real time.
In order to ensure a refrigerating effect and safety and stability of equipment during operation of the air conditioner, the air conditioner has a plurality of operation modes. Among these modes, the defrost mode is a special operation mode for frosting the surface of the evaporator inside the air conditioner. When the air conditioner is switched from other modes (such as refrigeration, heating, ventilation and the like) to the defrosting mode, the control system of the PFC circuit starts to monitor and control the working state of the air conditioner in real time.
In the defrosting mode, a control system in the air conditioner monitors the first voltage of the air conditioner in real time according to the set parameters and the real-time environmental conditions. The first voltage refers to the voltage of the air conditioner in the defrosting mode.
Step S120: and controlling to start or stop the PFC circuit according to the first voltage and the first setting range which are acquired currently.
After the first voltage is determined. The first voltage is used as a reference for determining whether the voltage is within a set range. Once the first voltage is determined, the PFC circuit needs to be controlled according to the relationship between the first voltage currently acquired and the first set range.
When the first voltage is within the first set range, measures are needed to start the PFC circuit. This is because, in this range, stability of the voltage is ensured, the PFC circuit is started, and the PFC circuit can further improve stability of the voltage by improving the power factor, improving the quality of power supply, and ensuring normal operation of the electrical equipment. At this time, we can optimize the performance of the air conditioner by adjusting the components in the PFC circuit, such as the capacitor, the inductor, etc.
Conversely, when the first voltage is outside the first set range, we need to turn off the PFC circuit. This is because the stability of the voltage may be affected at this time, and starting the PFC circuit may instead cause the voltage to fluctuate more, adversely affecting the electrical equipment (for example, if the voltage continues to decrease, the current may be too high and shut down). In this case, we should turn off the PFC circuit in time to avoid degradation of the circuit performance.
In summary, when the first voltage is processed, we need to flexibly adjust the control strategy of the PFC circuit according to the relationship between the voltage and the set range. The PFC circuit is turned on when the voltage is stable, and the PFC circuit is turned off when the voltage is unstable, so that the stability of the voltage and the normal operation of the electrical equipment can be ensured.
Step S130: under the condition of starting the PFC circuit, if the continuously acquired first voltage is out of the first set range, the PFC circuit is closed.
Step S140: under the condition of closing the PFC circuit, if the continuously acquired first voltage is within a first set range within a preset time, the PFC circuit is started.
To better achieve voltage control, regular detection and maintenance of PFC circuits is also required. By monitoring the voltage change in real time, the problem of voltage stability can be found in time, and corresponding measures can be taken.
Specifically, in the case of turning on the PFC circuit, if the continuously acquired first voltages are all outside the first set range, the PFC circuit needs to be turned off. This is because, when the voltage exceeds the set range, the PFC circuit may not be able to effectively perform voltage regulation, and may even cause damage to the device. Therefore, it is necessary to turn off the PFC circuit in time.
In the case of turning off the PFC circuit, if the continuously acquired first voltages are within the first set range for the preset time, it should be considered to turn on the PFC circuit again. This is because the PFC circuit can exert its function under the condition of stable voltage, thereby improving the utilization ratio of electric power and reducing the energy consumption of the device.
In addition, the setting range and the preset time of the PFC circuit are required to be reasonably adjusted. According to the actual running condition of the power system and the change of the load, the voltage setting range and the preset time of the PFC circuit are adjusted so as to realize more accurate voltage control.
The control method of the PFC circuit in the air conditioner provided by the invention aims at the real-time adjustment of the PFC function of the air conditioner according to the real-time operation condition of the air conditioner when the air conditioner operates in a defrosting mode. The method effectively improves the stability and reliability of the air conditioner in the running process, and brings more comfortable and convenient use experience for users.
In particular embodiments, the construction of the air conditioner is more complex than conventional air conditioners because it incorporates an additional component, the compressor. The compressor plays a vital role in an air conditioning system and is responsible for compressing a refrigerant from a gaseous state to a liquid state, thereby achieving a refrigerating effect of the air conditioner.
During operation of the air conditioner, when a PFC (power factor correction) circuit is turned on, it is electrically connected to the compressor. The connection is used for enabling the PFC circuit to adjust the current of the compressor, improving the utilization rate of the current and reducing the energy consumption. In the process, the PFC circuit can optimize the current of the compressor, so that the current of the compressor is more stable in the running process, and the overall performance of the air conditioner is improved.
Conversely, when the PFC circuit is turned off, it is disconnected from the compressor. This is because in this case the PFC circuit is no longer required for the conditioning system to regulate the current in order to avoid unnecessary burden on the compressor and other electrical equipment. Closing the PFC circuit helps to extend the service life of the air conditioning apparatus, while also helping to reduce the failure rate of the apparatus.
In conclusion, the design ensures the refrigerating effect of the air conditioner, and simultaneously can realize the efficient utilization of energy sources and reduce the running cost. By reasonably controlling the opening and closing of the PFC circuit, the air conditioner can be automatically adjusted under different operating environments, and the optimal performance is realized. The energy utilization rate of the air conditioner is improved, the burden on the environment is reduced, and the energy-saving and environment-friendly requirements of the current society are met.
As shown in fig. 2 and 3, before the step of acquiring the first voltage of the air conditioner in real time in the case that the air conditioner is in the defrosting mode, the method further includes:
Step S210: and acquiring a second voltage of the air conditioner in real time.
In this step, the air conditioning system monitors and records the second voltage value of the air conditioner in real time. This voltage value will be used as an important basis for judging the working state of the air conditioner.
Step S220: and judging whether the second voltage acquired currently is in a second setting range or not.
And judging whether the second voltage acquired currently is in a second setting range or not. At this stage, the system compares the second voltage value measured in real time with a predetermined second voltage range.
Step S230: and judging whether the air conditioner is in a defrosting mode or not under the condition that the second voltage is out of a second set range.
Step S240: and under the condition that the second voltage is in a second set range, starting the PFC circuit and controlling the compressor to start at the last shutdown frequency.
When the second voltage is outside the second set range, it is necessary to determine whether the air conditioner is in the defrost mode. When it is determined that the defrosting mode is in, the process proceeds to step S110. And when the defrosting mode is judged not to be in, switching to other control modes.
Then, in the case that the second voltage is within the second set range, the air conditioner may be operated normally. At this time, we need to turn on PFC circuit, which is an important part of the control system of the air conditioner. The PFC circuit controls various operation parameters of the air conditioner, and ensures that the air conditioner operates in an optimal state.
Furthermore, when the second voltage is within the second set range, we need to control the compressor to start at the last stop frequency. This is to prevent the compressor from generating excessive current during the start-up process, thereby affecting the stable operation of the air conditioner. The last shutdown frequency refers to the operating frequency of the compressor prior to the last shutdown. By starting the compressor at this frequency, a smooth transition of the compressor during the start-up process can be ensured, avoiding damage to the air conditioner.
As shown in fig. 3 and 4, in the case that the second voltage is outside the second set range, the step of determining whether the air conditioner is in the defrost mode further includes:
Step S410: and in the case that the air conditioner is not in the defrosting mode, closing the PFC circuit.
Step S420: and adjusting the PFC circuit according to the continuously acquired second voltage and the second setting range.
In the case where the air conditioner is not in the defrost mode, we need to turn off the PFC circuit. This is because it has been previously determined that the second voltage currently acquired is not in the second setting range, and is not adapted to the PFC circuit, and closing the PFC circuit helps to ensure the normal operation of the air conditioner.
After the PFC circuit is turned off, the PFC circuit needs to be adjusted according to the second voltage and the second setting range that are continuously acquired. The second voltage and the second setting range are important parameters for measuring the running state of the air conditioner, and by adjusting the parameters, better effect of the air conditioner in the defrosting process can be achieved.
In adjusting the PFC circuit, close attention is required to the variation of the second voltage. If the second voltage obtained continuously is within the second set range within the preset time, the current running state of the air conditioner is stable, and the PFC circuit is started. The start-up of the PFC circuit helps to improve the energy efficiency of the air conditioner.
However, if the second voltage that continues to be acquired is outside the second set range, this means that an abnormal operation condition of the air conditioner may occur. In this case, we should immediately turn off the PFC circuit to prevent the abnormal operation from damaging the air conditioner. Meanwhile, the air conditioner needs to be further checked to find out the reason of abnormal operation, and corresponding maintenance and adjustment are performed.
In summary, through the adjustment to the PFC circuit, the stable operation of the air conditioner can be ensured in real time, and the operation stability of the air conditioner is improved.
Based on the above embodiment, it should be noted that the first setting range u= (a+1) ×u 1, range parameterU 1 is the rated voltage of the current region, X is the initial judgment coefficient, and B is the high-temperature compensation coefficient.
Wherein, the range parameter A is that the upper and lower limit value can be positive or negative. The initial determination coefficient of X is 1, which decreases year by year, and the decreasing coefficients of different models are different, for example, it may be 0.1.B corresponds to a high temperature compensation coefficient, which is relatively higher when the high temperature duration is longer.
Typically, a is typically ±0.1, i.e. the first set range is 90% to 110% of the rated voltage of the current region.
In addition, the second setting range is different from the first setting range in value range so as to adapt to different working modes of the air conditioner. For example, the second setting range U 2＝(C+1)×U1, where the range parameter C corresponds to other parameters; u 1 is the rated voltage of the current region.
It can be understood that the air conditioner has a plurality of working modes when in operation, and a group of corresponding control parameters (setting range) can be independently set for adapting the PFC circuit and the air conditioner to work in an optimal state.
For example, the air conditioner should set different setting ranges in a fresh air mode, a cooling mode or a heating mode, and compare the different setting ranges with the current voltage to adjust the PFC circuit of the air conditioner.
