The following describes the components of the energy saving device of the air conditioner in detail with reference to fig. 2:

For example, the processor 11 is a Central Processing Unit (CPU), an Application Specific Integrated Circuit (ASIC), or one or more Integrated circuits configured to implement embodiments of the present invention, such as: one or more Digital Signal Processors (DSPs), or one or more Field Programmable Gate Arrays (FPGAs).

Also, as an example, the energy saving device of the air conditioner may include a plurality of processors, such as the processor 11 and the processor 15 shown in fig. 2. Each of these processors may be a Single-core processor (Single-CPU) or a Multi-core processor (Multi-CPU). A processor herein may refer to one or more devices, circuits, and/or processing cores for processing data (e.g., computer program instructions).
The Memory 12 may be a Read-Only Memory (ROM) or other type of static storage device that can store static information and instructions, a Random Access Memory (RAM) or other type of dynamic storage device that can store information and instructions, an Electrically Erasable Programmable Read-Only Memory (EEPROM), a Compact Disc Read-Only Memory (CD-ROM) or other optical Disc storage, optical Disc storage (including Compact Disc, laser Disc, optical Disc, digital versatile Disc, blu-ray Disc, etc.), magnetic disk storage media or other magnetic storage devices, or any other medium that can be used to carry or store desired program code in the form of instructions or data structures and that can be accessed by a computer, but is not limited to such. The memory 12 may be self-contained and coupled to the processor 11 via a communication bus 14. The memory 12 may also be integrated with the processor 11.
In a specific implementation, the memory 12 is used for storing data in the present invention and software programs for executing the present invention.

It should be noted that, in the embodiment of the present invention, the energy saving device of the air conditioner may be a split type air conditioner, a window type air conditioner, a mobile air conditioner, or other refrigeration equipment, or may be a remote controller corresponding to the refrigeration equipment.
In order to solve the problem of electric energy waste caused by low energy efficiency when an air conditioner is used for cooling or heating, an embodiment of the present invention provides an energy saving method for an air conditioner, as shown in fig. 3, the method may include:
201. and after entering the energy-saving mode, determining the operating frequency of the compressor according to the difference value between the set temperature and the current indoor temperature.
When the air conditioner is in a cooling or heating mode, and when the energy-saving device of the air conditioner determines to enter the energy-saving mode, the operating frequency of the compressor can be calculated according to the difference value between the set temperature of the user and the current indoor temperature. The energy-saving device of the air conditioner can determine to enter the energy-saving mode when receiving the triggering operation of a user on an energy-saving key on the energy-saving device of the air conditioner.
202. The operating frequency is compared to the first frequency and the second frequency.
The first frequency and the second frequency may be threshold values pre-stored in an energy saving device of the air conditioner, the first frequency is a lower threshold value, and the second frequency is a maximum allowable operating frequency in the energy saving mode. And the energy efficiency ratio corresponding to any frequency which is greater than or equal to the first frequency and less than or equal to the second frequency is greater than or equal to the preset energy efficiency ratio.
Illustratively, in conjunction with fig. 1, assuming the preset energy efficiency ratio is 3, the first frequency is 13Hz and the second frequency is 75 Hz.
203. And determining a target operating frequency according to the comparison result, wherein the target operating frequency is greater than or equal to the first frequency and less than or equal to the second frequency.
Wherein the energy saving device of the air conditioner may determine the target operation frequency according to the comparison result after comparing the operation frequency with the first frequency and the second frequency. Specifically, if the operating frequency is greater than or equal to the first frequency and less than or equal to the second frequency, the operating frequency is determined as the target operating frequency; if the operating frequency is greater than the second frequency, determining the second frequency as a target operating frequency; if the operating frequency is less than the first frequency, the first frequency is determined to be the target operating frequency. Thus, the target operation frequency is always in the frequency band with relatively high energy efficiency, and the energy saving of the air conditioner is realized.
For example, assuming that the operation frequency determined by the energy saving device of the air conditioner according to the temperature difference is 80 hertz (Hz), the first frequency is 20Hz, and the second frequency is 60Hz, fig. 4 is a schematic diagram of a power curve and a power consumption difference relationship of the compressor respectively operating at the frequency of 80Hz and the frequency of 60Hz, wherein the power consumption difference refers to a difference between the power consumption of the compressor operating at the frequency of 80Hz and the power consumption of the compressor operating at the frequency of 60Hz in a certain period of time, as shown in fig. 4, when the compressor is controlled to operate at the frequency of 60Hz instead of the frequency of 80Hz in the prior art, the maximum operation power of the air conditioner can be reduced from 1080 watts (W) to 780W, which effectively reduces the peak load of the power grid. And as can be seen from fig. 4, the power consumption of the compressor operating at a frequency of 60Hz is always less than the power consumption of the compressor operating at a frequency of 80Hz, indicated by 0.32KW/h in the table of fig. 4: the compressor operates for 5 hours and 30 minutes at the frequency of 60Hz, and saves electricity consumption compared with 5 hours and 30 minutes at the frequency of 80 Hz.
204. And controlling the compressor to operate at the target operation frequency.
After the target operation frequency is determined, the energy-saving device of the air conditioner can control the compressor to operate at the target operation frequency. When the user switches to other modes, for example, the current cooling or heating mode is switched to a dehumidification mode, an air supply mode or the like, or the user reenters the cooling or heating mode, the energy-saving device of the air conditioner exits the energy-saving mode, and the user can reenter the energy-saving mode by re-triggering the energy-saving key.
Further, in the embodiment of the present invention, the energy saving device of the air conditioner may further adjust the upper threshold of the operating frequency according to the triggering operation of the user, so as to improve the user experience. Specifically, as shown in fig. 5, before the step 202, the method may further include:
205. and determining the number of times of triggering the energy-saving key by the user within the preset time after the triggering operation is received.
The energy-saving device of the air conditioner can start timing after receiving the triggering operation of the energy-saving key by the user, determine the triggering times N of the energy-saving key by the user within the preset time, and compare the triggering times N with the preset times M. If the triggering times N are greater than the preset times M, the upper limit threshold value is not updated, and the pre-stored second frequency is still used; if the triggering time N is less than or equal to the preset time M, the upper threshold is updated, and specifically, the following step 206 may be performed:
206. and if the triggering times are less than or equal to the preset times, updating the second frequency according to the second frequency, the triggering times and a prestored third frequency.
And the third frequency represents the frequency value for triggering the reduction of the energy-saving key once. If the triggering time N is less than or equal to the preset time M, the energy saving device of the air conditioner may adopt the following formula: f2 ═ F2-F3 × N, and the updated second frequency F2' is determined, where F2 is the prestored second frequency, F3 is the prestored third frequency, and N is the number of triggers. Accordingly, step 202 is to compare the operating frequency with the first frequency and the updated second frequency.
The energy-saving method of the air conditioner provided by the invention is characterized in that after the operating frequency of the compressor is determined according to the temperature difference, the operating frequency is compared with the pre-stored first frequency and second frequency, and the target operating frequency is determined according to the comparison result so as to control the compressor to operate under the target operating frequency, wherein the target operating frequency is greater than or equal to the first frequency and less than or equal to the second frequency. Because the energy efficiency ratio corresponding to any frequency in the range taking the first frequency as the lower limit and the second frequency as the upper limit is larger than or equal to the preset energy efficiency ratio, the compressor can operate in a frequency section with high energy efficiency ratio, and the purpose of energy conservation is achieved. And, through setting up the upper limit value of target operating frequency, not only can alleviate the electric wire netting load when the power consumption peak, moreover indirect restriction the temperature of the air outlet of air conditioner, avoided the too fast rising or the reduction of temperature of air outlet, improved user experience.
