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, 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.
Fig. 1 is a schematic flow chart of a method for controlling an operation mode of an air conditioner based on a load according to the present invention.
In order to further describe the method for controlling the operation mode of the air conditioner based on the load provided by the present invention, the following description will be made with reference to fig. 1.
In an exemplary embodiment of the present invention, as can be seen in fig. 1, a method for controlling an operation mode of an air conditioner based on a load may include steps 110 to 130, and each step will be described below.
In step 110, in the case that the utility power grid does not supply power normally, the air conditioner is controlled to operate according to the lowest operating power gear of the energy saving mode.
In step 120, the total current supplied to the unit space and the total current of the load of the additional power consumers in the unit space are monitored in real time in the case that the air conditioner is operated in the lowest operation power gear.
In one embodiment, the total supply current and the total load current may be monitored in real time based on the signal receiving module. The signal receiving module can be connected with the input end of the stock power supply, so that the total power supply current in the unit space can be obtained based on the current value flowing into the input end of the stock power supply. The signal receiving module can be connected with the output end of the stock power supply, so that the total load current in the unit space can be obtained based on the current value flowing out of the output end of the stock power supply. The sources of the stock power sources can be community power generation, a commercial power grid, a personal generator and the like.
In step 130, a target operating power gear of the air conditioner in the energy saving mode is determined based on the total supply current and the total load current, and the air conditioner is controlled to operate according to the target operating power gear.
The additional power consumption electric appliance is other electric appliances except for the air conditioner in the unit space, such as an electric lamp, a television, a refrigerator and the like. The unit space may be a space formed in units of a user's home.
In one embodiment, the power source of the air conditioner may be derived from an indoor stand-by power outlet, wherein the indoor stand-by power outlet may be powered based on mains electricity to ensure continuous and efficient operation of the air conditioner. When the utility power grid does not normally supply power, the air conditioner can not operate according to the preset mode, and if the operation mode of the air conditioner is not adjusted in time, the air conditioner is stopped due to current limiting.
In the application process, when the fact that the commercial power grid does not normally supply power is monitored, the air conditioner can be automatically controlled to operate according to the lowest operation power gear of the energy-saving mode. The air conditioner operates according to the lowest operation power gear, namely the outdoor unit of the air conditioner operates according to the lowest operation power gear.
It will be appreciated that in the event that the utility grid fails to function properly, the user may also be able to draw power in other ways, such as a community generator or a home small generator to compensate. In addition, if the total load electricity consumption in the unit space is small, the air conditioner can not be operated according to the lowest operation power gear, and the personalized requirements of users cannot be effectively met.
In the application process, the total power supply current L0 in the unit space and the total load current L1 of the additional power consumption electric appliances in the unit space can be further monitored in real time under the condition that the air conditioner operates according to the lowest operating power gear. And determining a target operation power gear of the air conditioner in the energy-saving mode based on the total power supply current L0 and the total load current L1, and controlling the air conditioner to operate according to the target operation power gear.
The target operating power gear can be determined in an individualized way according to the current practical temperature condition on the premise that the available total current is not exceeded, so that the target operating power gear of the air conditioner in the energy-saving mode can be adjusted in an individualized way according to the electricity load of the unit space on the premise that the air conditioner cannot stop due to current limiting, and the experience and satisfaction of a user in the use process are improved.
In a further exemplary embodiment of the invention, it may be determined that the utility grid is not normally powered in the following manner:
determining the receiving condition of the signal receiving module for receiving the characterization signal, wherein the signal receiving module has the capability of receiving the characterization signal; the characterization signal is sent by a signal sending module, the signal sending module is powered by a mains supply grid, and the characterization signal is a preset frequency band signal;
and under the condition that the signal receiving module does not receive the characterization signal, determining that the commercial power grid does not normally supply power.
In one embodiment, the signal transmission module and the signal receiving module can also be characterized by wireless signal transmission under the condition that the signal transmission module is normally powered, including but not limited to Wifi, NB-IOT, loRa, zigBee. The signal transmitting module transmits the characterization signal, the signal receiving module receives the characterization signal, and the characterization signal and the signal receiving module are transmitted through wireless signals, so that multi-node control can be realized, the coverage area is wide, the power consumption is low, the influence of power grid operation fluctuation is small, signal transmission distortion caused by the influence of voltage fluctuation on the characterization signal is avoided, and the transmission of the characterization signal can be realized independently of the power grid operation condition.
In one embodiment, the signal receiving module may be installed beside the indoor unit of the air conditioner or built-in inside the indoor unit. The power source of the signal receiving module can be a power source from the indoor unit, and the signal wire is connected with the signal receiving module and the computer board of the indoor unit, so that signal transmission can be performed to the indoor unit based on the signal receiving module.
In yet another embodiment, the signaling module may be capable of transmitting the characterizing signal when the utility grid may be providing power to the signaling module normally. In other words, the signal sending module supplies power to the utility power grid, and if the utility power grid can supply power to the utility power grid, the signal sending module can send the characterization signal. Further, since the signal receiving module has the capability of receiving the characterization signal, the signal receiving module can receive the characterization signal when the signal transmitting module can transmit the characterization signal. In addition, when the utility power grid supplies power to the signal sending module normally, in other words, the utility power grid can supply power to the electric appliance normally, the signal receiving module can receive the characterization signal in the scene. When the utility power grid cannot normally supply power to the signal transmission module, in other words, the utility power grid cannot normally supply power to the electric appliance, the signal receiving module cannot receive the characterization signal in the scene.
Based on the characteristic signal receiving condition received by the signal receiving module, whether the commercial power grid supplies power normally can be determined. In an example, in the event that the signal receiving module does not receive the characterizing signal, it is determined that the utility grid is not normally powered. Through the embodiment, whether the commercial power grid supplies power normally can be automatically judged at lower cost.
According to the method for controlling the operation mode of the air conditioner based on the load, the air conditioner is controlled to operate according to the lowest operation power gear of the energy-saving mode under the condition that the commercial power grid does not normally supply power; under the condition that the air conditioner operates according to the lowest operating power gear, monitoring the total current of power supply in the unit space and the total current of load of an additional power consumption electric appliance in the unit space in real time; the target operation power gear of the air conditioner in the energy-saving mode is determined based on the total power supply current and the total load current, and the air conditioner is controlled to operate according to the target operation power gear, so that the target operation power gear of the air conditioner in the energy-saving mode is individually adjusted according to the power consumption load of the unit space on the premise that the air conditioner cannot stop due to current limiting, and the experience and satisfaction of a user in the use process are improved.
Fig. 2 is a schematic flow chart of determining a target operating power gear of the air conditioner in an energy saving mode based on a total power supply current and a total load current.
The process of controlling the operation mode of the air conditioner based on the load will be described with reference to fig. 2.
In an exemplary embodiment of the present invention, as can be seen in conjunction with fig. 2, determining a target operating power level of the air conditioner in the energy saving mode based on the total supply current and the total load current may include steps 210 to 230, which will be described below.
In step 210, the total current available is determined based on the difference between the total current supplied and the total current of the load.
In step 220, a maximum operating power value corresponding to the total current available is determined based on the total current available.
In step 230, a target operating power gear of the air conditioner in the energy saving mode is determined based on the maximum operating power value.
The target operation power value corresponding to the target operation power gear is smaller than or equal to the maximum operation power value.
In one embodiment, the total power supply current L0 (corresponding to the total power supply current) and the other electrical appliance current L1 (corresponding to the total load current) may be monitored based on the signal receiving module. Further, the available total current l2=l0-L1 is determined based on the difference between the supply total current L0 and the load total current L1.
It is understood that the maximum current at which the air conditioner can operate is L2, and the maximum operating power value may be determined based on the maximum current L2 at which the air conditioner can operate. In other words, the operating power of the air conditioner must be less than or equal to the maximum operating power value.
In yet another embodiment, the target operating power gear of the air conditioner in the energy-saving mode can be determined based on the maximum operating power value, so that on the premise that the air conditioner is not stopped due to current limiting, the target operating power gear of the air conditioner in the energy-saving mode can be adjusted individually according to the electric load of the unit space, and experience and satisfaction of a user in the using process can be improved. In the application process, the target operating power gear is also determined based on the external temperature in a personalized manner, so that the final target operating power gear does not exceed the maximum operating power value and can be matched with the external temperature in a personalized manner.
Fig. 3 is a schematic flow chart of determining a target operating power gear of an air conditioner in an energy saving mode based on a maximum operating power value.
The process of determining a target operating power level of the air conditioner in the energy saving mode based on the maximum operating power value will be further described with reference to fig. 3.
In an exemplary embodiment of the present invention, as can be seen in conjunction with fig. 3, determining a target operating power gear of the air conditioner in the energy saving mode based on the maximum operating power value may include steps 310 to 360, and each step will be described separately.
In step 310, an outdoor temperature value of the unit space is acquired in real time.
In step 320, an initial operation power value of the air conditioner is determined based on the outdoor temperature value and a preset map, wherein the map includes correspondence between different outdoor temperature values and different operation power values.
In one embodiment, an outdoor temperature value of a unit space may be acquired in real time, and an initial operation power value of an air conditioner corresponding to the outdoor temperature value may be determined according to the outdoor temperature value.
In yet another example, the initial operating power value may be determined according to a preset mapping table. The mapping table includes correspondence between different outdoor temperature values and different operation power values. For example, when the outdoor temperature value is a ℃, the corresponding initial operation power value is akW. When the outdoor temperature value is B ℃, the corresponding initial operation power value is bkW.
In step 330, the indoor temperature value of the unit space is acquired in real time.
In step 340, an adjusted operating power value is determined based on the indoor temperature value and the initial operating power value.
In yet another embodiment, an indoor temperature value of the unit space may also be acquired, and a final operation power value (corresponding to the adjusted operation power value) may be determined based on the indoor temperature value and the initial operation power value together. With this embodiment, a feedback mechanism may be formed, for example in summer, because the indoor temperature may be cooler than the outdoor temperature, there may be a need to operate at the initial operating power value to cool. In order to conserve energy and meet user requirements, an adjusted operating power value may be determined based on the indoor temperature value and the initial operating power value.
In step 350, in the case where the adjusted operation power value is less than or equal to the maximum operation power value, the adjusted operation power value is taken as the target operation power value, and the target operation power gear of the air conditioner is determined based on the target operation power value.
In step 360, in the case that the adjusted operation power value is greater than the maximum operation power value, the maximum operation power value is taken as the target operation power value, and the target operation power gear of the air conditioner is determined based on the target operation power value.
In yet another embodiment, when the adjusted operation power value is less than or equal to the maximum operation power value, it is indicated that the operation mode of the air conditioner does not exceed the maximum operation power value that can be carried by the air conditioner under the condition that the operation mode is individually matched with the external temperature. In this scenario, the maximum operating power value may be taken as the target operating power value, and a target operating power gear of the air conditioner may be determined based on the target operating power value. By the embodiment, the air conditioner can operate according to the operation mode of personalized matching of the external temperature on the premise that the maximum operation power value carried by the air conditioner is not exceeded.
In yet another embodiment, when the adjusted operation power value is greater than the maximum operation power value, it is indicated that the operation mode of the air conditioner exceeds the maximum operation power value that the air conditioner can carry under the condition of individually matching the external temperature. In this scenario, the adjusted operating power value may be taken as the target operating power value, and a target operating power gear of the air conditioner may be determined based on the target operating power value.

Fig. 4 is a schematic flow chart of determining an adjusted operating power value based on an indoor temperature value and an initial operating power value according to the present invention.
The process of determining the adjusted operating power value based on the indoor temperature value and the initial operating power value will be described below with reference to fig. 4.
In an exemplary embodiment of the present invention, as can be appreciated in conjunction with fig. 4, determining the adjusted operating power value based on the indoor temperature value and the initial operating power value may include steps 410 through 430, each of which will be described separately below.
In step 410, a temperature difference between the outdoor temperature value and the indoor temperature value is determined.
In step 420, an operating power adjustment value is determined based on the temperature difference;
in step 430, an adjusted operating power value is determined based on the initial operating power value and the operating power adjustment value.
In one embodiment, for a scenario where the outdoor temperature value is greater than the indoor temperature value, the temperature difference may be derived based on a difference between the outdoor temperature value and the indoor temperature value.
In yet another embodiment, for a scenario in which the outdoor temperature value is less than the indoor temperature value, the temperature difference may be obtained based on a difference between the indoor temperature value and the outdoor temperature value.

Fig. 5 is a second flowchart of a method for controlling an operation mode of an air conditioner based on a load according to the present invention.
Another process of controlling the operation mode of the air conditioner based on the load will be described with reference to fig. 5.
In an exemplary embodiment of the present invention, as can be seen in fig. 5, the method for controlling the operation mode of the air conditioner based on the load may include steps 510 to 540, wherein steps 510 to 530 are the same as or similar to steps 110 to 130, and the specific implementation and the beneficial effects thereof are as described above, but the embodiment is not limited thereto, and step 540 will be described below.
In step 540, in the case that the signal receiving module receives the characterization signal, the air conditioner is controlled to operate according to the current operation mode.
It can be understood that, since the characterization signal is emitted by the signal sending module, if the utility power grid can supply power normally, the signal sending module can emit the characterization signal, and then the signal receiving module can receive the characterization signal in a preset time period. Therefore, if the signal receiving module can receive the characterization signal in the preset time period, it can be stated that the utility power grid can normally supply power; if the signal receiving module cannot receive the characterization signal within the preset time period, the fact that the commercial power grid cannot supply power normally is indicated.
In one embodiment, the normal supply of the utility grid is illustrated when the signal receiving module receives the characterization signal within a preset time period.
Further, when the situation that the commercial power grid can supply power normally is detected, the fact that the local power grid is sufficient in power supply is indicated. In this scenario, the air conditioner is not required to be adjusted to perform the energy-saving mode, but is still controlled to operate according to the current operation mode. Through the embodiment, the air conditioner can be ensured to operate according to the setting of a user under the condition that the power supply of the power grid is sufficient, so that the experience and satisfaction of the user can be improved.
In this embodiment, it can be determined whether the utility power grid can normally supply power without adding additional cost, and further, the operation mode of the air conditioner can be automatically controlled at low cost, so that the experience and satisfaction degree of the user in the use process can be improved.
In yet another exemplary embodiment of the present invention, the characterization signal may be transmitted between the signal transmitting module and the signal receiving module in the following manner:
and loading the characterization signal on the current formed by the mains supply power grid, and transmitting the characterization signal on the power line so that the characterization signal is transmitted to the signal receiving module by the signal sending module, wherein the mains supply power grid forms the current under the condition that the mains supply power grid supplies power normally, and the power line has the signal transmission capability.
In one embodiment, a high voltage power line, a medium voltage power line, or a low voltage distribution line may be utilized as an information transmission medium instead of WIFI, infrared transmission. The signal transmission module can be used for acquiring a preset frequency band signal in the mains supply grid, modulating the preset frequency band signal and obtaining a modulated signal (which can correspond to the characterization signal). And loading the modulated signal to a power line for transmission. It should be noted that, under the condition that the utility power grid supplies power normally, the power line has the signal transmission capability. In other words, under the condition that the utility power grid supplies power normally, the signal receiving module can receive the signal sent by the signal sending module.
Further, at the signal receiving module end, when the signal receiving module receives the modulated signal based on the power line, the modulated signal can be demodulated again based on the signal receiving module to obtain a demodulated signal, and whether the demodulated signal includes a preset frequency band signal or not is judged. If the demodulated signal comprises a preset frequency band signal, the utility power grid can supply power normally. Through the embodiment, the transmission of the characterization signals can be ensured to be only related to the normal power supply condition of the commercial power grid, and the influence of whether the WIFI communication signals are good or not and whether the infrared transmission distance is close enough or not can be avoided, so that the accurate receiving condition of the characterization signals received by the signal receiving module can be ensured, and whether the commercial power grid is normally supplied or not can be determined.
Fig. 6 is a schematic diagram of an application scenario of the method for controlling an operation mode of an air conditioner based on a load.
To further describe the method for controlling the operation mode of the air conditioner based on the load provided by the present invention, the following description will be made with reference to fig. 6.
In an exemplary embodiment of the present invention, as can be seen in fig. 6, for a region where power supply is deficient, each home may be configured with an electrically controlled switching box (corresponding to the power conversion device in fig. 6) placed outdoors, and the electrically controlled switching box may be divided into an input terminal and an output terminal. As can be seen from fig. 6, the input terminal is composed of personal power generation, community power generation and commercial power. The output may be connected with the stock power source 1 to the stock power source N. In the application process, the power supply of the input end can come from respective power supplies, such as commercial power, community power generation, personal power generator and the like, and the power supply of the output end is connected to a household stock power socket (corresponding to the stock power supply). In addition, the mains supply is directly connected to a household mains supply socket (corresponding to the mains supply) for use by the unnecessary continuous electric appliance. The indoor unit 1 of the present invention may be powered by a normal power supply.
In fig. 6, N represents a zero line, and L represents a live line. S2 represents a signal connection line between the indoor unit and the outdoor unit. The indoor unit 1 and the receiving module (corresponding to the signal receiving module of the present invention) may be connected through a signal line to ensure signal transmission therebetween.
In one example, the transmit module (corresponding signaling module) may be mounted in a three-pin plug format. The transmitting module may be powered by mains electricity. The receiving module is arranged beside the indoor unit 1 or internally arranged in the indoor unit, the power supply mode of the receiving module is from the indoor unit power supply, and the receiving module is connected with the indoor unit computer board through a signal wire, so that the signal transmission of the receiving module is ensured.
The air conditioner power supply can come from an indoor stock power socket, continuous operation is guaranteed, the transmitting module is inserted into an indoor commercial power socket, the receiving module is arranged on or beside the indoor unit, the number of the receiving modules is not limited to 1, the number of the receiving modules is equal to the number of the indoor units according to the number of the air conditioners arranged at home, and only one transmitting module can be used or a plurality of transmitting modules can be used.
In the application process, when the commercial power is normally supplied, the transmitting module is provided with a power supply to supply power to the receiving module, signals can be normally transmitted to the receiving module, the power line carrier communication is normal, the receiving module only performs signal analysis, does not issue an energy-saving command, and the air conditioner can operate according to the user setting.
When the commercial power is not available, other power supply forms supply power to the household, the commercial power socket is in a non-power state, the transmitting module cannot transmit signals to the receiving module, and the program sets the receiving module to send commands to the computer version in the air conditioner so as to enable the air conditioner to enter an energy-saving mode, control the air conditioner to operate in an energy-saving mode, and ensure that other electrical appliances can operate under the condition of limited power capacity. Therefore, the operation of the air conditioner can be automatically controlled to meet the actual condition of power supply, and the experience and satisfaction of a user in the use process are improved on the premise that the normal operation of other electric appliances is ensured.
Further, when the air conditioner enters the energy-saving mode for the first time and operates according to the lowest gear of the energy-saving mode, the receiving module can detect the total current L0 of the power supply source (corresponding to the total current of the power supply) and the electric current L1 of other electric appliances (corresponding to the total current of the load) after entering the energy-saving mode, and find out the residual usable current L2=L0-L1 (corresponding to the total usable current) of the air conditioner. And the operating frequency of the compressor of the outdoor unit is regulated according to the maximum current of the air conditioner being L2, so that the current L in the operation process of the air conditioner is always less than or equal to L2-a, wherein a is a current correction value, the air conditioner is ensured not to stop due to current limiting, and specific parameters are adjustable. In the following, it will be described how the current L during operation of the air conditioner is always at < L2-a. The detection of the total current L0 of the power supply can flow to the receiving module through an S0 signal connecting wire; the other electric current L1 can flow to the receiving module through the S1 signal connecting wire.
In one example, outdoor temperature values for a unit space may be acquired in real time; and determining an initial operation power value of the air conditioner based on the outdoor temperature value and a preset mapping table. Further, an adjusted operating power value is determined based on the indoor temperature value and the initial operating power value. When the adjusted operation power value is smaller than or equal to the maximum operation power value, taking the adjusted operation power value as a target operation power value, and determining the target operation power gear of the air conditioner based on the target operation power value; and under the condition that the adjusted operation power value is larger than the maximum operation power value, taking the maximum operation power value as a target operation power value, and determining a target operation power gear of the air conditioner based on the target operation power value.
According to the method for controlling the operation mode of the air conditioner based on the load, the air conditioner is controlled to operate according to the lowest operation power gear of the energy-saving mode under the condition that the commercial power grid is not normally supplied with power; under the condition that the air conditioner operates according to the lowest operating power gear, monitoring the total current of power supply in the unit space and the total current of load of an additional power consumption electric appliance in the unit space in real time; the target operation power gear of the air conditioner in the energy-saving mode is determined based on the total power supply current and the total load current, and the air conditioner is controlled to operate according to the target operation power gear, so that the target operation power gear of the air conditioner in the energy-saving mode is individually adjusted according to the power consumption load of the unit space on the premise that the air conditioner cannot stop due to current limiting, and the experience and satisfaction of a user in the use process are improved.
