Example 1
In accordance with an embodiment of the present invention, there is provided a method embodiment of adjusting an operating frequency of a wind turbine, where the steps illustrated in the flowchart of the drawings may be implemented in a computer system, such as a set of computer executable instructions, and where a logical order is illustrated in the flowchart, in some cases, the steps illustrated or described may be performed in an order different than that illustrated or described herein.
Fig. 1 is a flowchart of a method for adjusting an operating frequency of a wind turbine according to an embodiment of the present invention, and as shown in fig. 1, the method for adjusting an operating frequency of a wind turbine includes the following steps:
step S102, after the outdoor unit of the air conditioner is powered on and started, the initial operation frequency of a fan corresponding to the outdoor unit is determined based on the detected first parameter of the outdoor unit.
In actual engineering installation of the air conditioner, conditions for installing the outdoor unit are diversified. Because the outdoor units have different installation conditions, the capacity of the outdoor units has certain influence on the running frequency of the fans, for example, if the running frequency of the fans of the outdoor units with small capacity is too high, the reliability of the outdoor units is influenced, extra power consumption is caused, and extra cost is increased.
Therefore, after the outdoor unit is powered on, the air conditioner automatically detects parameters such as the current operating state of the outdoor unit, the capacity of the outdoor unit, and the installation conditions of the outdoor unit (e.g., the ambient temperature, the static pressure, etc. of the area where the outdoor unit is located) to determine the initial operating frequency of the fan corresponding to the outdoor unit.
That is, the first parameter may include at least one of: current operation state of the outdoor unit, capacity of the outdoor unit, and installation conditions of the outdoor unit.
Fig. 2 is a flowchart of a method for determining an initial operating frequency of a fan according to an embodiment of the present invention, and as shown in fig. 2, the method includes the following steps:
step S201 starts.
Step S202, determining that the outdoor unit is in a normal operation state.
Step S203, detecting the ambient temperature of the outdoor unit, the installation static pressure of the outdoor unit, and the capacity of the outdoor unit, and obtaining a detection result.
And S204, determining the initial operating frequency of the fan according to the detection result.
It should be noted that, when the static pressure of the outdoor unit is higher and the outdoor environment temperature is higher, the initial operation frequency of the outdoor unit is also higher.
And step S104, acquiring a second parameter of the outdoor unit in the process that the fan operates at the initial operating frequency.
For example, the second parameter may be: the current operation capacity of the outdoor unit, the actual capacity of the outdoor unit, the ambient temperature of the outdoor unit, the defrosting times and defrosting time of the outdoor unit, and the like.
And step S106, determining a correction value required to correct the initial operating frequency of the fan according to the second parameter.
And step S108, adjusting the initial operation frequency based on the correction value.
Through the steps, after the outdoor unit of the air conditioner is powered on and started, the initial operating frequency of the fan corresponding to the outdoor unit is determined based on the detected first parameter of the outdoor unit; then, in the process that the fan runs at the initial running frequency, a second parameter of the outdoor unit is obtained; determining a correction value required to correct the initial operating frequency of the fan according to the second parameter; and adjusting the initial operating frequency based on the correction value. Compared with the defect that the air conditioner cannot meet the requirements of users only by means of controlling the operating frequency of the fan by means of high and low voltages of the air conditioner in the related art, the method for adjusting the operating frequency of the fan provided by the embodiment of the invention can achieve the purpose of adjusting the operating frequency of the fan by detecting parameters such as the ambient temperature, the defrosting times and the defrosting time of the outdoor unit, achieve the technical effects of improving the operating reliability and comfort of the outdoor unit, and further solve the technical problem that the method for controlling the operating frequency of the fan of the air conditioner in the related art is low in reliability.
In step S106, determining a correction value that needs to be corrected for the initial operating frequency of the fan according to the second parameter may include: and after the second parameter is obtained, analyzing the second parameter, and determining a correction value required to correct the initial operating frequency of the fan based on the analysis result obtained by analysis.
In the embodiment of the present invention, the operation frequency of the fan of the outdoor unit is mainly affected by at least one of the following factors: the method comprises the following steps of starting the operation frequency of a fan, the current operation capacity of the outdoor unit, the actual capacity of the outdoor unit, the environment temperature of the outdoor unit, and the defrosting times and defrosting time of the outdoor unit. It should be noted that the operation frequency of the fan of the outdoor unit may also be influenced by other factors. The following description is made.
In one aspect, in the case that the second parameter is the current operation capacity of the outdoor unit and the actual capacity of the outdoor unit, in step S106, determining a correction value that needs to be corrected for the initial operation frequency of the fan according to the second parameter may include: determining a ratio I of the current operation capacity of the outdoor unit to the actual capacity of the outdoor unit; judging whether the ratio I is smaller than a first threshold value or not to obtain a first judgment result; under the condition that the first judgment result shows that the first ratio is smaller than the first threshold, determining a first correction value which needs to correct the initial operating frequency of the fan; and determining a correction value four which needs to correct the initial operating frequency of the fan under the condition that the first judgment result shows that the ratio I is not less than the first threshold value. Here, the first correction value is not 0, and the fourth correction value is 0.
The current operation capacity represents the capacity required when the indoor unit is actually started. For example, one outdoor unit a is a unit connected with 5 indoor units, and the capacity of the unit is 280 hundred watts (i.e., the actual capacity of the outdoor unit is 280 hundred watts), and currently, only 2 indoor units of the 5 indoor units connected with the outdoor unit a are in an operating state, so the current operating capacity of the outdoor unit may be 150 hundred watts.
That is, in the multi-split system, one outdoor unit is connected to a plurality of indoor units, or a plurality of outdoor units are connected to a plurality of indoor units in actual installation. According to the requirements of actual users, the starting number of the indoor units is not fixed, so that the capacities of the outdoor units in actual operation are different, the heat exchange born by each outdoor unit is also inconsistent, and the running frequencies of fans of the outdoor units are also different.
In this case, the adjusting the initial operating frequency based on the correction value in step S108 may include: when the first judgment result shows that the ratio I is smaller than the first threshold value, reducing the initial operation frequency by a first correction value; and determining that the initial operating frequency does not need to be adjusted based on the correction value four under the condition that the first judgment result shows that the ratio I is not less than the first threshold value.
Fig. 3 is a flowchart of adjusting the initial operating frequency based on a correction value according to an embodiment of the present invention, and as shown in fig. 3, in a case where it is determined that the outdoor unit normally operates, the capacity actually allocated by the outdoor unit (i.e., the current operating capacity of the outdoor unit) is detected, a ratio (i.e., a ratio of two) of the capacity actually allocated by the outdoor unit to the actual capacity of the outdoor unit is calculated, and when it is determined that the initial operating frequency of the fan needs to be corrected according to the determined ratio of two (i.e., in a case where the first determination result indicates that the ratio of one is smaller than the first threshold), a first correction value that the initial operating frequency of the fan needs to be corrected is determined, and the initial operating frequency is decreased by the first correction value, so as to achieve the.
And when the first judgment result shows that the ratio I is not less than the first threshold, the correction value IV is 0, that is, the initial operating frequency is determined not to be adjusted based on the correction value IV.
On the other hand, in the case that the second parameter is the ambient temperature of the area where the outdoor unit is located, in step S106, determining a correction value that needs to correct the initial operating frequency of the fan according to the second parameter may include: when the ambient temperature of the area where the outdoor unit is located reaches the preset temperature of the air conditioner, determining a second ratio of the current operation capacity of the outdoor unit to the target operation capacity of the outdoor unit; judging whether the ratio II is smaller than a second threshold value or not to obtain a second judgment result; determining a second correction value which needs to correct the initial operating frequency of the fan under the condition that the second judgment result shows that the second ratio is smaller than a second threshold value; and determining a correction value four which needs to correct the initial operating frequency of the fan under the condition that the second judgment result shows that the ratio value two is not less than the second threshold value. Here, the second correction value is not 0, and the fourth correction value is 0.
For example, the ambient temperature of the outdoor unit is not always constant during the operation of the outdoor unit, and the ambient temperature is constantly changed during the day. When the ambient temperature is increased or decreased, the output frequency of a fan of the outdoor unit can be adjusted to improve the operation reliability of the outdoor unit, so that the actual requirements of customers are met. Specifically, after the air conditioner starts to operate, the operation state of the outdoor unit is automatically detected, and the ambient temperature and the current operation capacity of the outdoor unit are monitored in real time. When the air conditioner operates in a cooling/heating mode, if the ambient temperature reaches the preset temperature of the air conditioner, calculating a second ratio of the current operation capacity of the outdoor unit to the target operation capacity, and if the second ratio is smaller than a second threshold, indicating that the operation capacity of the target outdoor unit is low, the operation frequency of a fan of the outdoor unit needs to be increased, namely, the operation frequency of the fan needs to be adjusted, otherwise, controlling the fan to operate at the current operation frequency, namely, the correction value of the current operation frequency of the fan is 0. In the refrigeration mode, the higher the ambient temperature is, the larger the frequency adjustment value of the fan of the outdoor unit is; conversely, in the heating mode, the lower the ambient temperature is, the larger the frequency adjustment value of the fan of the outdoor unit is.
In this case, the adjusting the initial operating frequency based on the correction value in step S108 may include: under the condition that the second judgment result shows that the ratio II is smaller than the second threshold value, increasing the initial operation frequency by a second correction value; and determining that the initial operating frequency does not need to be adjusted based on the correction value four under the condition that the second judgment result shows that the ratio value two is not less than the second threshold value.
Fig. 4 is a flowchart illustrating an alternative adjustment of the initial operating frequency based on a correction value according to an embodiment of the present invention, as shown in fig. 4, when it is determined that the outdoor unit normally operates, it is determined that the initial operating frequency of the fan needs to be adjusted, an ambient temperature of the outdoor unit and a current operating capability of the outdoor unit are detected, a ratio (i.e., a ratio three) between the current operating capability and a target operating capability is determined, when it is determined that the initial operating frequency of the fan needs to be corrected according to the determined ratio, a correction value two for correcting the initial operating frequency is determined, and the initial operating frequency is increased by the correction value two, so as to achieve an object of accurately adjusting the initial operating frequency of the fan.
On the other hand, in step S106, in the case that the second parameter is the defrosting time of the outdoor unit and the defrosting time of the outdoor unit, determining a correction value that needs to be corrected for the initial operating frequency of the fan according to the second parameter may include: determining a current operation state of the air conditioner; when the current running state of the air conditioner is in a refrigeration mode, determining a correction value four for correcting the initial running frequency of the fan; when the current operation state of the air conditioner is in a heating mode, determining a correction value four for correcting the initial operation frequency of the fan if the first defrosting time of the outdoor unit is not more than the preset defrosting time and the first defrosting time of the outdoor unit is not more than the preset defrosting time; and under the condition that the current operation state of the air conditioner is in a heating mode, if the first defrosting time of the outdoor unit is greater than the preset defrosting time, and the first defrosting time of the outdoor unit is greater than the preset defrosting time, determining a third correction value which needs to correct the initial operation frequency of the fan. Here, the correction value three is not 0, and the correction value four is 0.
For example, when the air conditioner is in the cooling operation mode, the outdoor unit may discharge heat to the air, and the outdoor unit does not frost, so the defrosting correction is 0 (i.e., the correction value is four); on the contrary, when the air conditioner operates in the heating mode, the outdoor unit can absorb heat in the air, and at the moment, if the high pressure is too low, the surface of the condenser is very easy to frost, and the use of the air conditioner is influenced by frequent frosting of the outdoor unit, so that the initial operation frequency needs to be adjusted.
In this case, the adjusting the initial operating frequency based on the correction value in step S108 may include: under the condition that the current operation state of the air conditioner is in a heating mode, if the first defrosting time of the outdoor unit is greater than the preset defrosting time, and the first defrosting time of the outdoor unit is greater than the preset defrosting time, increasing the initial operation frequency by a third correction value; when the current operation state of the air conditioner is in a heating mode, determining that the initial operation frequency does not need to be adjusted based on the correction value IV under the conditions that the first defrosting time of the outdoor unit is not more than the preset defrosting time and the first defrosting time of the outdoor unit is not more than the preset defrosting time; and when the current running state of the air conditioner is in the cooling mode, determining that the initial running frequency does not need to be adjusted based on the correction value IV.
Fig. 5 is a flowchart illustrating an adjustment of the initial operation frequency based on the correction value according to another embodiment of the present invention, as shown in fig. 5, when it is determined that the outdoor unit is in the on operation state, it is determined whether the outdoor unit is in the heating mode; if so, after the outdoor unit is operated for a preset heating time period, detecting the defrosting times and defrosting time of the outdoor unit in the preset time period, determining a third correction value for correcting the initial operating frequency of the fan when the initial operating frequency of the fan needs to be corrected based on the detected defrosting times and defrosting time, and increasing the initial operating frequency by the third correction value; and under the condition that the judgment result is no, determining that the correction value for correcting the initial operation frequency of the fan is 0.
It should be noted that the defrosting time in the embodiment of the present invention refers to the time required for the last defrosting of the multiple times of defrosting of the outdoor unit in a predetermined time period.
In an optional embodiment, after the initial operating frequency is adjusted based on the correction value, the method for adjusting the operating frequency of the wind turbine may further include: acquiring defrosting times II and defrosting time II of the outdoor unit; determining a correction value V which needs to correct the adjusted initial operating frequency of the fan under the condition that the second defrosting time is greater than the preset defrosting time and the second defrosting time is greater than the preset defrosting time; and adjusting the initial operating frequency of the adjusted fan by using the correction value five. Here, the correction value five is not 0.
Specifically, the adjusting the initial operating frequency of the adjusted fan by using the correction value five may include: and increasing the adjusted initial operating frequency of the fan by a correction value five.
For example, after an outdoor unit is operated for a predetermined time period for heating, the defrosting times n and the defrosting time t of the outdoor unit in the predetermined time period are detected. When the defrosting times are not more than the preset defrosting times and the defrosting time is not more than the preset defrosting time, determining that the current operating frequency of the fan of the outdoor unit is within a reasonable range, and continuing to operate the fan at the current operating frequency; on the contrary, when the current operating frequency of the fan is determined to be smaller, the current operating frequency of the fan needs to be increased. And after the initial operating frequency of the fan is corrected, the condition that the defrosting time is not more than the preset defrosting time is still not met, and when the defrosting time is not more than the preset defrosting time, the adjusted operating frequency of the fan is adjusted again.
It should be noted that the number of times of adjusting the operating frequency of the fan is not unlimited, but at most cannot exceed a predetermined number of times of adjustment.
That is, the larger the defrosting time of the outdoor unit is, the longer the defrosting time is, which indicates that the operating frequency of the fan of the outdoor unit is relatively low, and the fan frequency needs to be increased until the defrosting time and the defrosting time of the outdoor unit meet the following conditions: the defrosting times are not more than the preset defrosting times, and the defrosting time is not more than the preset defrosting time.

Specifically, the initial operating frequency of the fan is adjusted by using the sum of the first correction value and the second correction value. And when the initial operation frequency of the fan is determined not to be adjusted, determining the correction value to be 0, namely, the initial operation frequency of the fan is not required to be adjusted.
That is, the second parameter includes both: when the current operation capacity of the outdoor unit, the actual capacity of the outdoor unit, and the ambient temperature of the outdoor unit are used, the initial operation frequency of the fan needs to be adjusted according to the sum of the first correction value and the second correction value caused by the current operation capacity of the outdoor unit, the actual capacity of the outdoor unit, and the ambient temperature of the outdoor unit, so as to improve the accuracy of correcting the initial operation frequency of the fan.
