The implementation manner of the present application will be further described in detail below with reference to the drawings and embodiments. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

In the description of the embodiments of the present application, the terms "first" and "second" are used for description purposes only, and cannot be understood as indicating or implying relative importance.

In the description of the embodiments of this application, it should be noted that unless otherwise specified and limited, the terms "connected" and "connected" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection, Or integrated connection; it can be mechanical connection or electrical connection; it can be direct connection or indirect connection through an intermediary. Those of ordinary skill in the art can understand the specific meanings of the above terms in the embodiments of the present application in specific situations.

In the description of this specification, descriptions referring to the terms "one embodiment", "some embodiments", "example", "specific examples", or "some examples" mean that specific features described in connection with the embodiment or example , structures, materials or features are included in at least one embodiment or example of the embodiments of the present application. In this specification, the schematic representations of the above terms are not necessarily directed to the same embodiment or example. Furthermore, the described specific features, structures, materials or characteristics may be combined in any suitable manner in any one or more embodiments or examples. In addition, those skilled in the art can combine and combine different embodiments or examples and features of different embodiments or examples described in this specification without conflicting with each other.

The present application provides an energy-saving control method for an air conditioner, which may be a wall-mounted air conditioner, a cabinet-type air conditioner, a window-type air conditioner, or a ceiling-mounted air conditioner. As shown in Figure 1, the control method for energy saving of the air conditioner includes the following steps:

Step S110: Obtain the season of the scene where the air conditioner is located.

During the operation of the air conditioner, the user may control the air conditioner through an electronic device or a remote controller. In this process, if the air conditioner receives an instruction to turn on the energy-saving function, the air conditioner can use sensors or cloud servers to obtain the season information of the current scene, thereby judging the season of the current scene. If the air conditioner does not receive an instruction to turn on the energy-saving function, it maintains the current working state.

For example, when the air conditioner is cooling or heating the room, after the air conditioner receives an instruction to activate the energy-saving function, it can judge the season through information such as temperature and humidity detected by the sensor, or obtain the season of the current scene through the cloud server.

Step S120: Based on the working mode of the air conditioner, determine the preset power corresponding to the season.

Since the air conditioner works differently when cooling and heating, after obtaining the seasonal information, first judge the current working mode of the air conditioner, and select the corresponding preset power according to the different working modes.

If it is determined that the air conditioner is in the cooling mode, the preset cooling power of the air conditioner is determined according to the cooling condition of the air conditioner in the season. If it is determined that the air conditioner is in the heating mode, the preset heating power of the air conditioner is determined according to the heating condition of the air conditioner in the season.

Specifically, if the air conditioner is in the condition of spring cooling, the preset cooling power is determined according to the corresponding working conditions of spring cooling. If the air conditioner is in the cooling state in summer, the preset cooling power is determined according to the corresponding working conditions of cooling in summer. If the air conditioner is in the cooling state in autumn, the preset cooling power is determined according to the corresponding working conditions of the cooling in autumn. If the air conditioner is in the cooling condition in winter, the preset cooling power is determined according to the corresponding working condition of cooling in winter.

If the air conditioner is in the spring heating state, the preset heating power is determined according to the corresponding working conditions of the spring heating. If the air conditioner is in the heating state in summer, the preset heating power is determined according to the corresponding working conditions of the summer heating. If the air conditioner is in the heating state in autumn, the preset heating power is determined according to the corresponding working conditions of the autumn heating. If the air conditioner is in the heating state in winter, the preset heating power is determined according to the corresponding working conditions of the winter heating.

Step S130: Control the operation of the air conditioner based on the preset power.

After determining the preset power, the preset power is the total power of the air conditioner, including the power of the compressor, indoor fan, outdoor fan and other structures. Controlling the operation of the air conditioner based on the preset power can avoid using voltage or current alone for control. Problems that affect the cooling or heating effect, and running the air conditioner with a certain power can ensure the stable operation of the air conditioner in the scene of voltage fluctuations.

The air conditioner energy-saving control method provided in this application, by obtaining the season of the scene where the air conditioner is located, according to the working mode of the air conditioner, judges the preset power corresponding to the season; finally uses the preset power to control the operation of the air conditioner, for different seasons , on the premise of ensuring the working effect of the air conditioner as much as possible, reduce the energy consumption of the air conditioner when it is working, and improve the user experience. .

Based on the above embodiment, as shown in FIG. 2, according to the heating condition of the air conditioner in the season, the step of determining the preset cooling power of the air conditioner includes:

Step S210: If the air conditioner is cooling in spring or autumn, determine that the preset cooling power is the limited cooling power.

During the cooling process of the air conditioner, in order to reduce the energy consumption of the air conditioner, as the temperature drops, it is necessary to adjust the cooling power of the air conditioner accordingly.

When the air conditioner is cooling in spring or autumn, determine the preset cooling power as the cooling limit power, limit the power operation of the air conditioner, and reduce the energy consumption of the air conditioner.

Step S220: If the air conditioner is cooling in summer, determine that the preset cooling power is the rated cooling power.

When the air conditioner is cooling in summer, it is determined that the preset cooling power is the cooling limit power, that is, the air conditioner needs to operate normally in order to ensure the air conditioning effect during cooling in summer.

Step S230: If the air conditioner is cooling in winter, then determine the preset cooling power as the cooling stop power.

When the air conditioner is cooling in winter, the preset cooling power is determined to be the cooling shutdown power, that is, the air conditioner can be stopped for internal circulation during cooling in winter.

Specifically, during cooling in spring, due to the moderate temperature, in order to reduce energy consumption, the power operation of the air conditioner can be limited, and the energy consumption of the air conditioner can be reduced by operating at 70% of the rated power. When cooling in autumn, run at 80% of the rated power to reduce the energy consumption of the air conditioner. During cooling in summer, in order to ensure the air conditioning effect, the air conditioner needs to operate normally at 100% of the rated power. When cooling in winter, due to the low temperature, the air conditioner can be shut down for internal circulation.

Based on the above embodiment, as shown in FIG. 3 , according to the heating condition of the air conditioner in the season, the step of determining the preset heating power of the air conditioner includes:

Step S310: If the air conditioner is heating in spring or autumn, determine that the preset heating power is the heating limit power.

During the heating process of the air conditioner, in order to reduce the energy consumption of the air conditioner, as the temperature rises, the heating power of the air conditioner needs to be adjusted accordingly.

When the air conditioner is heating in spring or autumn, the preset heating power is determined as the heating limit power, and the power operation of the air conditioner is limited to reduce the energy consumption of the air conditioner.

Step S320: If the air conditioner is heating in summer, then determine the preset heating power as the heating shutdown power.

When the air conditioner is heating in summer, the preset heating power is determined to be the heating shutdown power, that is, the air conditioner can be stopped for internal circulation during heating in summer.

Step S330: If the air conditioner is heating in winter, determine that the preset heating power is the rated heating power.

When the air conditioner is heating in winter, the preset heating power is determined to be the limited heating power, that is, the air conditioner needs to operate normally in order to ensure the air conditioning effect during heating in winter.

In some remote areas, the voltage is unstable. In order to ensure the energy-saving operation of the air conditioner in these areas, step S130: based on the preset power, the steps of controlling the operation of the air conditioner include:

Step S1301: Obtain adjustment parameters.

As shown in Figure 4, the adjustment parameters can be obtained before obtaining the season of the scene where the air conditioner is located. At 210-230V.

If the input voltage is in the preset range, and the input voltage is in the range of 210-230V, the step of obtaining the season of the scene where the air conditioner is located is directly performed.

If the input voltage is outside the preset range, and the input voltage is outside 210-230V, the adjustment parameter is determined based on the ratio of the input voltage to the rated voltage.

Step S1302: Adjust the preset power based on the adjustment parameter, and determine a new preset power.

After the adjustment parameters are determined, the preset power can be directly adjusted in proportion to determine a new preset power. New preset power=preset power×adjustment parameter.

Step S1303: Control the operation of the air conditioner based on the preset power and the new preset power.

In order to reduce the energy consumption of the air conditioner when the voltage is high, when the new preset power is greater than the preset power, the operation of the air conditioner can be controlled based on the preset power. When the new preset power is less than or equal to the preset power, the operation of the air conditioner is controlled based on the new preset power. Thus, it can be ensured that when the voltage is relatively high, the operation of the air conditioner can be controlled with a relatively small preset power, thereby reducing the energy consumption of the air conditioner. When the voltage is too small, the preset power can be adjusted by adjusting the parameters to ensure the operation of the air conditioner.
