Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Because most of the existing air conditioner power saving modes are that a user sets an ECO power saving mode through a remote controller, the air conditioner automatically changes the lower limit of the refrigeration set temperature and the upper limit of the heating set temperature, and controls the operating frequency and power of a press through the set temperature of the user, thereby preventing the temperature from being too cold or too hot and achieving the purpose of saving power. Although the method can achieve the effect of saving power to a certain extent, if the indoor temperature can not reach the set temperature all the time, the power consumption of the air conditioner will not change, and the purpose of saving power can not be achieved. Moreover, some users do not want to change the set temperature, but want to save power, and this method cannot meet the personalized requirements of the users. Therefore, the embodiment of the invention provides an air conditioner power saving method which is used for solving the technical problems in the prior art.
Fig. 1 is a schematic flow chart of a power saving method for an air conditioner according to an embodiment of the present invention, as shown in fig. 1, the method includes:
s1, acquiring a target power saving gear set by a user, and determining a current threshold range corresponding to the target power saving gear, wherein the current threshold range is determined based on the slow down frequency point current and the up frequency point current of the air conditioner;
and S2, detecting the current value of the air conditioning press, and adjusting the current value to be within the current threshold range.
Specifically, in the power saving method for an air conditioner provided in the embodiment of the present invention, the execution main body may be a built-in controller of the air conditioner, so as to implement power saving control of the air conditioner.
Step S1 is executed first to obtain a target power saving gear set by the user, where the target power saving gear may be set by the user through a remote controller of the air conditioner. The remote controller can be provided with an ECO power saving mode, after the user selects the ECO power saving mode, a display panel of the remote controller or a display panel of the air conditioner displays each power saving gear of the air conditioner for the user to select, and the user selects a proper target power saving gear according to the requirement. In the embodiment of the present invention, the power saving gears of the air conditioner may include at least two gears, preferably three gears, and the operating power ranges from low to high are L1, L2, and L3, and the operating power ranges corresponding to L1, L2, and L3 are sequentially increased, and the power saving level is sequentially decreased.
After the user sets the power saving gear in the target, a target gear setting instruction can be generated, and the target gear setting instruction is used for representing the target power saving gear set by the user. The controller may receive the target gear setting instruction, and the reception of the target gear setting instruction indicates that the target power saving gear set by the user is obtained.
The controller may store a corresponding relationship between each power saving gear and a current threshold range, the current threshold range may include an upper current threshold and a lower current threshold, the upper current threshold may be a current at a slow down frequency point of the compressor in the air conditioner, and the lower current threshold may be a current at an up frequency point of the compressor in the air conditioner. After the controller acquires the target power-saving gear, the controller can determine the current threshold range corresponding to the target power-saving gear according to the stored corresponding relation.
Four current values are corresponding to each power saving gear in the air conditioner, and as shown in fig. 2, the four current values respectively comprise a stop point current value I1, a fast frequency-reduction point current value (1Hz/S) I2, a slow frequency-reduction point value (1Hz/10S) I3 and an ascending point current value I4 of a compressor in the air conditioner, and the four current values can be preset. Because the current threshold range is related to the running frequency of the compressor in the air conditioner, the controller determines the current threshold range corresponding to the target power saving gear, the change of the running frequency of the compressor in the air conditioner can be limited through the target power saving gear set by a user, and a theoretical basis is provided for the power saving of the air conditioner.
Then, step S2 is executed. The current value of the air conditioning press is detected, and the current value can be determined through elements such as an ammeter and a current transformer, and can also be determined through a sampling circuit, which is not specifically limited in the embodiment of the invention. After the current value is detected, the current value may be adjusted to be within a current threshold range. When the current value is adjusted to be within the current threshold range, the running frequency of the air conditioner press can be limited between the slow down frequency point and the up frequency point, and therefore power saving is achieved.
According to the air conditioner power saving method provided by the embodiment of the invention, the power saving gear is associated with the running frequency of the compressor in the air conditioner, the corresponding current threshold range can be determined through the target power saving gear set by a user, and then the running frequency of the compressor of the air conditioner can be limited between the slow down frequency point and the up frequency point by adjusting the current value of the compressor of the air conditioner to be within the current threshold range, so that the power saving is realized. The power saving effect realized by the method is not limited by the temperature set by the user, can be realized under the condition that the set temperature is not changed, and can also realize power saving even if the indoor temperature can not reach the set temperature all the time. Moreover, the target power saving gear is set by the user independently, so that the individual requirements of the user can be met, the system is more humanized, and the experience of the user is improved.

Specifically, in the embodiment of the invention, when the current value of the air conditioning press is adjusted, the current value can be achieved through a closed-loop control strategy, that is, the operation frequency of the air conditioning press is controlled through the closed-loop control strategy. The closed-loop control strategy may be a PID control strategy, or may be other control strategies, which is not specifically limited in the embodiment of the present invention.
In the embodiment of the invention, the current value of the air conditioner compressor is adjusted through a closed-loop control strategy, so that the adjusting process is more refined, and the adjusting result is more reliable.

and adjusting the rotating speed of the outdoor air conditioner fan based on the operating frequency and the outdoor environment temperature.
Specifically, in the embodiment of the present invention, after the operating frequency of the air conditioning compressor is controlled by adjusting the current value to be within the current threshold range, the operating frequency of the air conditioning compressor and the outdoor ambient temperature may also be obtained. The operating frequency of the air conditioning press can be detected by the frequency detection device, and the outdoor environment temperature can be acquired by the temperature sensor.
After the operating frequency and the outdoor environment temperature of the air conditioning compressor are obtained, the rotating speed of the outdoor air conditioning fan can be adjusted according to the operating frequency and the outdoor environment temperature. The adjusting mode can be that firstly, the optimal rotating speed is determined according to the corresponding relation among the operating frequency, the outdoor environment temperature and the rotating speed of the outdoor air-conditioning fan, and then the rotating speed of the outdoor air-conditioning fan is adjusted according to the optimal rotating speed, namely the rotating speed of the outdoor air-conditioning fan is adjusted to the optimal rotating speed.
In the embodiment of the invention, the rotating speed of the outdoor air-conditioning fan is adjusted according to the operating frequency of the air-conditioning press and the outdoor environment temperature. On the basis that the power saving effect is realized by adjusting the current value to the current threshold value range to control the running frequency of the air conditioner compressor, the power saving effect is further realized by controlling the rotating speed of the outdoor air conditioner fan, and the power saving effect is more obvious.

Specifically, in the embodiment of the present invention, when the rotation speed of the outdoor air-conditioning fan is adjusted, the controller may store in advance a corresponding relationship between the operating frequency range of the air-conditioning press, the outdoor environment temperature range, and the rotation speed of the outdoor air-conditioning fan. The division of the operating frequency range of the air conditioning press and the outdoor environment temperature range can be performed according to needs, and the number of corresponding ranges can also be set according to needs, which is not specifically limited in the embodiment of the invention. For example, the operating frequency f (Hz) of the air conditioning press is divided into three operating frequency ranges of the air conditioning press by using A, B (A is less than or equal to B) with f being less than A, A, f is less than or equal to B and f is more than or equal to B. By utilizing two outdoor environment temperature given values of T1 and T2(T1 is not less than T2), the outdoor environment temperature T is divided into three outdoor environment temperature ranges, namely T is less than T1, T is not less than T1 and not more than T2, and T is not less than T2. Different operating frequency ranges of the air conditioning compressor and different outdoor environment temperature ranges correspond to different rotating speeds of the outdoor air conditioning fan, and the specific corresponding relation can be shown in table 1.
