As known from the background art, the existing air conditioner is not adapted to the electricity consumption environment, so that the air conditioner cannot safely operate in an unstable power grid environment and electricity is wasted.
Therefore, the embodiment of the invention provides a method for adapting the operating frequency of an air conditioner to the electricity utilization environment and related equipment, in the scheme, the electricity utilization type of a conduction signal is detected, if the conduction signal is detected to be the conduction signal generated by a private enterprise, the operating frequency of the air conditioner is switched to a power gear, when the current voltage of the air conditioner is detected to be a preset percentage of the normal voltage, the operating frequency of the air conditioner is changed according to the current voltage, so that the operating frequency of the air conditioner is adapted to the electricity utilization environment, the matching of the operating frequency of the air conditioner with the local electricity utilization environment is realized, the safe operation of the air conditioner in an unstable power grid environment is ensured, and meanwhile, the intelligent electricity saving is realized.
As shown in fig. 1, a flow chart of a method for adapting an operating frequency of an air conditioner to an electrical environment is provided in an embodiment of the present invention, where the method for adapting the operating frequency of the air conditioner to the electrical environment mainly includes the following steps:
step S101: in the running process of the air conditioner, when the air conditioner computer board receives the conduction signal, the electricity utilization type of the conduction signal is detected.
In step S101, the on signal is identified by the detecting device in the running state, and is sent to the air conditioner computer board by the detecting device in a level signal mode.
The electricity consumption type of the conduction signal comprises a municipal power generation conduction signal and a private enterprise power generation conduction signal.
Fig. 2 is a circuit diagram of actual wiring between an air conditioner and a power supply party according to an embodiment of the present invention.
In fig. 2, the electric box is connected to municipal electricity and private enterprise electricity respectively, a detection device is arranged between one end of the electric box and the air conditioner indoor unit, the electric box is connected through a signal wire, and the other end of the electric box is connected to the user ammeter.
When private enterprises conduct electricity, the detection device which is always in operation can recognize the conducting information, and then the conducting signal is sent to the computer board of the air conditioner internal unit in a high-low level mode, namely, the conducting signal is sent to the air conditioner computer board in a high-low level mode.
In the specific implementation step S101, during the operation of the air conditioner, the air conditioner computer board receives the conduction signal, and when the air conditioner computer board receives the conduction signal, the electricity type of the conduction signal is detected, so as to detect whether the conduction signal is a conduction signal for private power generation or a conduction signal for municipal power generation.
Step S102: and judging whether the conduction signal is generated by a private enterprise, if so, executing the step S103, and if not, ending the operation.
In the specific implementation step S102, whether the conduction signal is a conduction signal generated by a private enterprise is determined, if yes, it is indicated that the power grid environment generated by the private enterprise is unstable, and the operation frequency of the air conditioner needs to be changed, so that the air conditioner can safely operate in the unstable power grid environment and save electricity, and therefore, step S103 is executed; if not, the on signal is the on signal of municipal power generation, and the air conditioner can safely operate and save electricity because the municipal power generation is stable, so that the operation is finished without changing the operation frequency of the air conditioner.
Step S103: and switching the operating frequency of the air conditioner to a power gear, and determining the normal voltage of the electricity environment where the air conditioner is positioned.
In step S103, the power gear is the Ln gear.
Assuming that the total running power of the air conditioner is 3000W, the l1 gear is 1500W, and the l2 gear is 2500W, the parameter can be set by a technician according to specific requirements, and the invention is not limited.
The electricity environment where the air conditioner is located is a power grid environment of a local area where the air conditioner is connected and obtains electric energy from the local area, and specifically, in the embodiment of the invention, the electricity environment where the air conditioner is located is a household electricity environment where electric energy is obtained from a power grid environment where private enterprises generate electricity, and also can be an office electricity environment where electric energy is obtained from the power grid environment where private enterprises generate electricity.
In the specific implementation process of step S103, under the condition that the conducting signal is determined to be a conducting signal generated by private enterprises, the running frequency of the air conditioner is switched to a power gear so as to achieve the effect of saving electricity, and then the normal voltage of the electricity utilization environment where the air conditioner is located, or the normal voltage of the current electricity utilization environment where the air conditioner is located, or the normal voltage of the local electricity utilization environment is determined.
It is understood that during operation of the air conditioner, the air conditioner computer board determines the normal voltage of the grid environment for private enterprises to generate electricity.
Step S104: the current voltage of the electricity consumption environment is detected.
In the specific implementation process of step S104, because different users have different distances from private enterprise power plants, the private enterprise power generation can be unstable, so that the air conditioner computer board detects the current voltage of the power utilization environment where the air conditioner is located, and the operation frequency of the air conditioner can be changed according to the current voltage.
Preferably, in a specific embodiment, the current voltage of the electricity consumption environment is detected at intervals of a preset time.
For example, the current voltage of the electricity usage environment is detected for each period T.
Step S105: and judging whether the current voltage is a preset percentage of the normal voltage, if so, executing the step S106, and if not, ending the operation.
In step S105, the preset percentage may be expressed as X%.
In the specific implementation step S105, whether the current voltage is a preset percentage of the normal voltage or not is determined, that is, whether the current voltage of the electricity environment where the air conditioner is located is X% of the normal voltage or not is determined, if yes, it is indicated that the electricity environment where the air conditioner is located is unstable, that is, the power grid environment where private enterprises generate electricity is unstable, and if the air conditioner cannot safely operate, the step S106 is executed; if not, the power consumption environment where the air conditioner is located is stable, namely the power grid environment where private enterprises generate power is stable, the air conditioner can safely run, and then the operation is finished.
Step S106: and adjusting the operating frequency of the air conditioner compressor.
In step S106, the operation frequencies of the air conditioner compressors are all pre-fixed in the corresponding parameters of the air conditioner computer board.
In the specific implementation process of step S106, when it is determined that the current voltage of the electricity environment where the air conditioner is located is a preset percentage of the normal voltage, that is, when it is determined that the current voltage of the electricity environment where the air conditioner is located is X% of the normal voltage, the operation frequency of the air conditioner compressor is adjusted based on the current voltage of the electricity environment where the air conditioner is located, which is detected by the air conditioner computer board.
Preferably, in a specific embodiment, if the current voltage is a preset percentage of the normal voltage, determining the normal frequency of the air conditioner compressor; and changing the operating frequency of the air conditioner compressor on the basis of the normal frequency.
As can be seen from the above, after the normal frequency of the air conditioner compressor is determined, the operating frequency of the compressor is changed based on the normal frequency.
Step S107: judging whether the current voltage is unstable or not, and judging whether the voltage change rate of the current voltage exceeds the preset voltage change rate or not, if so, executing the step S108, and if not, ending the operation.
In step S107, the preset voltage change rate may be denoted as K.
In the specific implementation step S107, whether the current voltage is unstable or not is determined, and whether the voltage change rate of the current voltage exceeds the preset voltage change rate, that is, whether the current voltage is unstable or not is determined, and whether the voltage change rate of the current voltage exceeds the preset voltage change rate K or not is determined, if yes, the power consumption environment of the air conditioner is unstable, that is, the power grid environment of private enterprise power generation is unstable, and the air conditioner cannot safely operate, then step S108 is executed; if not, the current voltage is stable, or the voltage change rate of the current voltage does not exceed the preset voltage change rate, namely the electricity utilization environment where the air conditioner is positioned is stable, namely the power grid environment where private enterprises generate electricity is stable, the air conditioner can safely run, and then the operation is finished.
Step S108: and analyzing the corresponding parameters of the current voltage.
In the specific implementation step S108, when it is determined that the current voltage is unstable and the voltage change rate of the current voltage exceeds the preset voltage change rate, that is, it is determined that the current voltage is unstable and the voltage change rate of the current voltage exceeds the preset voltage change rate K, the corresponding parameters of the current voltage of the electricity environment where the air conditioner is located are analyzed, specifically: the rate of change of voltage in the current voltage is analyzed.
Step S109: and judging whether the voltage change rate is smaller than or equal to the preset voltage change rate, if so, executing the step S110, and if not, executing the step S111.
In the specific implementation process of step S109, determining whether the voltage change rate is less than or equal to the preset voltage change rate, that is, determining whether the absolute value of the voltage change rate of the current voltage is within the absolute value of the preset voltage change rate, if yes, executing step S110; if not, it is indicated that the voltage change rate of the current voltage is greater than the preset voltage change rate, that is, the absolute value of the voltage change rate of the current voltage is greater than the absolute value of the preset voltage change rate, step S111 is performed.
Step S110: changing the operating frequency of the air conditioner compressor to a target frequency value according to the first frequency, and enabling the target frequency value to adapt to the current voltage.
In step S110, the first frequency is a frequency of nHz per minute.
In the specific implementation process of step S110, when the voltage change rate is less than or equal to the preset voltage change rate, the operating frequency of the air-conditioning compressor is changed to a target frequency value according to the first frequency, so that the target frequency value is adapted to the current voltage. That is, in determining that the absolute value of the voltage change rate of the current voltage is within the absolute value of the preset voltage change rate, the operating frequency of the air conditioner compressor is changed to the target frequency value at a frequency of nHz per minute, so that the target frequency value is adapted to the current voltage.
For example, if the voltage change rate |k1| is within |k|, the operation frequency of the air-conditioning compressor is changed to the target frequency value at the frequency of nHz per minute.
Step S111: and changing the operating frequency of the air conditioner compressor to a target frequency value according to the second frequency, so that the target frequency value is adapted to the current voltage.
In step S111, the second frequency is the frequency of mHz per minute.
In the specific implementation process of step S111, under the condition that the voltage change rate of the current voltage is determined to be greater than the preset voltage change rate, the operating frequency of the air conditioner compressor is changed to a target frequency value according to the second frequency, so that the target frequency value is adapted to the current voltage. That is, in the case where it is determined that the absolute value of the voltage change rate of the present voltage is greater than or equal to the absolute value of the preset voltage change rate, the operating frequency of the air conditioner compressor is changed to the target frequency value at the frequency of mHz per minute, so that the target frequency value is adapted to the present voltage.
For example, if the voltage change rate |k2| is equal to or greater than |k|, the operating frequency of the air-conditioning compressor is changed to the target frequency value at the frequency of mHz per minute.
For example, assuming that the current voltage of the electricity environment in which the air conditioner is located is 190V, the current voltage of the electricity environment in which the air conditioner is located is 200V, the voltage change rate is 10, the frequency value is 55Hz (target frequency value) from 46Hz (current frequency value), the frequency change value is 3Hz, and the frequency change value of the voltage change rate below 10 (for example, 6V) is 2Hz.
The calculation is specifically performed with reference to the following rules:
when the voltage change rate is a value of |k|, the frequency change value is YHz;
frequency change value n=y/(|k1|/|k|);
the frequency change value m=y/(|k2|/|k|).
Step S112: based on the current voltage, the operating frequency of the air conditioner is changed, so that the operating frequency of the air conditioner is adapted to the electricity utilization environment.
In the specific implementation step S112, after detecting the current voltage of the electricity environment where the air conditioner is located and determining that the current voltage is a preset percentage of the normal voltage, the air conditioner computer board stably outputs the current voltage, and changes the air conditioner operation frequency by using the current voltage, so that the air conditioner operation frequency is adapted to the electricity environment.
Based on the above, it can be understood that after changing the operation frequency of the air conditioner compressor to the target frequency value, the air conditioner computer board changes the operation frequency of the air conditioner based on the target frequency value, that is, the air conditioner computer board changes the operation frequency of the air conditioner based on the current voltage, so that the operation frequency of the air conditioner is adapted to the electricity consumption environment.
According to the method for adapting the operating frequency of the air conditioner to the electricity utilization environment, the electricity utilization type of the conduction signal is detected, if the conduction signal is detected to be the conduction signal generated by a private enterprise, the operating frequency of the air conditioner is switched to the power gear, when the current voltage of the air conditioner is detected to be a preset percentage of the normal voltage, the operating frequency of the air conditioner is changed according to the current voltage, so that the operating frequency of the air conditioner is adapted to the electricity utilization environment, the matching of the operating frequency of the air conditioner with the local electricity utilization environment is realized, the safe operation of the air conditioner in an unstable power grid environment is ensured, and meanwhile intelligent electricity saving is realized.
