Description
Technical Field
The invention relates to the technical field of air conditioners, in particular to a starting control method of an air conditioner.
Background
With the increasing living standard, the requirements of people on the quality of life are higher and higher, and the requirements are particularly obvious on household appliances. Taking an air conditioner as an example, in order to meet the requirement of a user for rapid cooling/heating and bring comfortable use experience to the user, when the conventional air conditioner is just started, the compressor is generally rapidly increased to a higher frequency (for example, the compressor is increased to the maximum working frequency). In the process of rapidly raising the frequency of the compressor to a high frequency, in order to ensure normal oil return, the compressor is usually forced to operate for a period of time at a certain or certain fixed frequency (oil return frequency), and the frequency is continuously raised after the oil return is stable. However, the arrangement mode of forcing the compressor to continuously operate for a period of time at the oil return frequency enables the frequency rising time of the compressor to be too long in the process of starting the air conditioner for rapid cooling/heating, and the speed of the compressor reaching the maximum working frequency is slowed down, so that the effect of rapid heating/cooling of the air conditioner is influenced.
In order to solve the above problems of the air conditioner, the patent application with publication number CN107576016A discloses a method and a system for controlling an air conditioner. Specifically, the control method mainly comprises the following steps: starting a compressor of an air conditioner; continuously increasing the frequency of the compressor in stages according to a plurality of set speeds; after the frequency is continuously increased in stages, judging whether the frequency of the compressor reaches a first target frequency; and stopping the frequency increasing of the compressor when the frequency of the compressor reaches the first target frequency. The application mainly shortens the frequency increasing time of the compressor and achieves the purpose of rapid refrigeration/heating by canceling the continuous operation stage on the oil return frequency in the frequency increasing process of the compressor and then enabling the compressor to continuously increase the frequency in stages at different frequency increasing speeds after the compressor is started. Although the above control method solves the problem of poor rapid heating/cooling effect in the prior art to a certain extent, the following defects are also unavoidable: first, not all users need to perform rapid cooling/heating after the air conditioner is turned on, nor are all users suitable for rapid cooling/heating under all environmental conditions, so the control method has a problem of poor universality in actual use. Secondly, the rapid frequency rise of the air conditioner can correspondingly cause the noise to be increased, and for some special users or occasions (such as insomnia users or libraries), the use experience of the users is greatly influenced by the generation of the noise.
Accordingly, there is a need in the art for a new method for controlling the start-up of an air conditioner to solve the above-mentioned problems.

and adjusting the rotating speed of the outer fan according to the corresponding relation between the outdoor environment temperature and/or the frequency of the compressor and the rotating speed of the outer fan.
In a preferred technical solution of the above starting control method of the air conditioner, the frequency increasing stage includes a plurality of frequency increasing sub-stages, the fitting formula correspondingly includes a plurality of fitting sub-formulas, and calculating the frequency increasing speed of the compressor at the frequency increasing stage according to the fitting formula further includes:
and respectively calculating the frequency increasing speed of each frequency increasing sub-stage of the compressor according to each fitting sub-formula.

and controlling the compressor to continuously increase the frequency according to the frequency increasing speed of each frequency increasing sub-stage.
In the preferable technical scheme of the starting control method of the air conditioner, the rotating speed of the inner fan is in direct proportion to the frequency increasing speed of the compressor.

The method for controlling the starting of the air conditioner can improve the universality of the air conditioner and improve the use experience of a user.
Specifically, the rotation speed of the inner fan is in direct proportion to the frequency increasing speed of the compressor. When the rotating speed of the inner fan is low, the user does not strongly want to control the air conditioner to perform quick cooling/heating, the frequency increasing speed of the compressor calculated according to the fitting formula is relatively low, the compressor performs frequency increasing according to the frequency increasing speed, and the noise can be reduced while the cooling/heating effect of the air conditioner is ensured; when the rotating speed of the inner fan is high, the fact that a user urgently needs the air conditioner to perform rapid cooling/heating is described, the frequency increasing speed of the compressor calculated according to the fitting formula is relatively high, the compressor performs frequency increasing according to the frequency increasing speed, the air conditioner can be rapidly cooled/heated, the cooling/heating time is greatly shortened, and good use experience is brought to the user. And through repeated tests, observation, analysis and comparison of the inventor, under the condition of adopting the technical scheme of the invention to carry out quick refrigeration/heating, the frequency increasing speed of the air conditioner can be increased by times or even tens of times compared with the prior art, and the frequency jump of the air conditioner is realized.

It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. For example, although the present invention is described with reference to the operation of an air conditioner in a cooling mode, such an application scenario is not always the same, and those skilled in the art may also apply the method of the present invention to other application scenarios, such as a heating mode or a dehumidifying mode of an air conditioner, without departing from the principle of the present invention.
First, it should be noted that, in general, air conditioners each include an indoor unit and an outdoor unit, where the indoor unit is provided with an indoor heat exchanger, an internal fan, and the like, and the outdoor unit is provided with a compressor, an electronic expansion valve, an external fan, an outdoor heat exchanger, and the like. The indoor unit is also usually provided with a control system for controlling the operation of the air conditioner, and the control system comprises a control module, a judgment module, a calculation module, an acquisition module and the like. The physical forms of the control module, the judgment module, the calculation module and the acquisition module may be independent from each other, and certainly, the control module, the judgment module, the calculation module and the acquisition module may also be functional units integrated on one physical module. The control system of the air conditioner comprises a memory, a processor and a computer program which is stored in the memory and can run on the processor, wherein the computer program can complete the functions of the control module, the judgment module and the acquisition module. The physical arrangement of the air conditioners is the conventional arrangement mode of the air conditioners in the prior art, and should not be considered as the limitation of the control method of the invention.
Referring to fig. 1, fig. 1 is a flowchart illustrating a method for controlling a start-up of an air conditioner according to the present invention.
As shown in fig. 1, in order to solve the problems of poor universality and poor user experience of the conventional start-up control method for the air conditioner, the invention provides a start-up control method for the air conditioner, which mainly comprises the following steps:
s100, acquiring the rotating speed of an inner fan; after the air conditioner is started and an operation mode (such as refrigeration) and an operation wind speed are selected by pressing a switch by a user, the air conditioner acquires the operation wind speed set by the user, namely the rotating speed of the inner fan, by receiving an instruction of the user.
S200, calculating the frequency rising speed of the compressor in the frequency rising stage according to a fitting formula, wherein if the fitting formula is determined according to the corresponding relation between the rotating speed of the inner fan and the frequency rising speed of the compressor, and if the rotating speed of the inner fan is higher and the rotating speed of the inner fan is higher in direct proportion relation with the frequency rising speed of the compressor, the frequency rising speed of the compressor is higher, and the frequency rising speed of the compressor in the frequency rising stage is calculated by an air conditioner control system according to the fitting formula;

s500, when the frequency of the compressor reaches the stable working frequency, the compressor stops increasing the frequency, and if the current frequency reaches the stable working frequency, the control system controls the compressor to maintain the stable working frequency to continue working.
According to the air conditioner starting control method, the universality of the air conditioner can be improved, and the use experience of a user can be improved. In other words, the method and the device solve the problems of poor universality and poor user experience of the conventional air conditioner starting control method, improve the comfort of the air conditioner and improve the user experience.
The principles of the present invention are further explained with reference to fig. 2. Fig. 2 is a graph of the rising speed of the compressor in the control method of the present invention.
In one possible embodiment, as shown in fig. 2, the compressor has only one frequency increasing stage, and the fitting formula of the frequency increasing stage is that the rotating speed of the inner fan is in a direct proportion relation with the frequency increasing speed of the compressor, and preferably, the frequency increasing speed is any value from 0.5Hz to 30 Hz. For example, the fitting formula of the up-conversion speed can be: v-krn+ b, where v represents the up-conversion speed (Hz/s) of the compressor, rnRepresenting the rotating speed (r/min) of the inner fan, k is a proportionality coefficient, and b is a constant. The scaling factor k and constant b of the fitting equation may be determined as follows: the wind speed of the air conditioner is assumed to be five from low to high, and the corresponding rotating speeds of the fans in the ground are rn1＝500r/min、rn2＝700r/min、rn3＝900r/min、rn4＝1200r/min、rn51500r/min, thereby, let rn1When the frequency is 500r/min, the frequency raising speed v1＝0.5Hz/s，rn5When the frequency is 1500r/min, the frequency raising speed v530Hz/s, k is 0.0295, b is-14.25, and v is therefore 0.0295rn-14.25. After the fitting formula is calculated, the fitting formula is preset in a control system of the air conditioner, so that after a user starts the air conditioner to select a mode and an air speed each time, the control system can determine the frequency increasing speed of the compressor and control the frequency increasing operation of the compressor according to the frequency increasing speed.
Referring now to table 1, in one possible embodiment, the stable operating frequency may be determined based on a correspondence between the outdoor ambient temperature and the stable operating frequency.

Wherein, TaoRepresenting the outdoor ambient temperature, fwRepresenting the stable operating frequency of the compressor, feRepresenting the nominal operating frequency of the compressor.
Referring to tables 2 and 3, in a possible embodiment, in order to better improve the experience of the user in using the air conditioner, improve the refrigeration effect, and improve the working stability and the service life of the compressor, the method for controlling the start-up of the air conditioner according to the present invention may further include the following steps:
and adjusting the opening degree of the electronic expansion valve according to the corresponding relation between the outdoor environment temperature and the frequency of the compressor and the opening degree of the electronic expansion valve.
And adjusting the rotating speed of the outer fan according to the corresponding relation between the outdoor environment temperature and the rotating speed of the outer fan.

Wherein, TaoRepresents the outdoor ambient temperature, rwRepresenting the rotational speed of the outer fan.
Through the control mode, the starting control method of the air conditioner has the advantages that: the method for controlling the starting of the air conditioner can improve the universality of the air conditioner and improve the use experience of a user. Specifically, the rotation speed of the inner fan is in direct proportion to the frequency increasing speed of the compressor. When the set wind speed is low, namely the rotating speed of the inner fan is low, the user does not strongly want to control the air conditioner to perform quick refrigeration, the frequency-increasing speed of the compressor calculated according to the fitting formula is relatively low, the compressor performs frequency-increasing according to the frequency-increasing speed, and the noise can be reduced while the refrigeration effect of the air conditioner is ensured; when setting for that the wind speed is high, when interior fan rotational speed is high promptly, explain that the user urgently needs the air conditioner to refrigerate fast this moment, the speed of raising the frequency of the compressor that calculates according to the fitting formula this moment is higher relatively, and the compressor carries out the raising the frequency according to this speed of raising the frequency, can make the air conditioner refrigerate fast, greatly shortens refrigerated time, produces cold wind fast, reduces indoor temperature, improves user experience. The parameters such as the stable working frequency of the compressor, the opening of the electronic expansion valve, the rotating speed of the outer fan and the like are correspondingly determined through the parameters such as the outdoor environment temperature, the working frequency of the compressor and the like.
Further, repeated experiments, observation, analysis and comparison of the inventor show that the frequency raising speed of the compressor can be stably controlled to be 0.5-30Hz/s on the premise of ensuring the stable operation of the compressor by accurately controlling the oil output of the compressor, the opening degree of the electronic expansion valve, the rotating speed of the outer fan, the oil-liquid separator and the like, and particularly the maximum frequency raising speed can reach astonishing 30 Hz/s. Those skilled in the art will appreciate that the prior art compressors typically have a frequency up-conversion rate of 0.5 to 1Hz/s, and that few compressors achieve the frequency up-conversion rate of the present invention while maintaining stable operation. Therefore, when the air conditioner performs quick refrigeration, the frequency increasing speed of the air conditioner can be increased by multiple times or even tens of times compared with the prior art, so that the frequency jump of the air conditioner is realized, and the use experience of a user is greatly improved.
Of course, the above embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art may also make any type of adjustment on the above parameters without departing from the principle of the present invention, as long as the adjusted technical solution can improve the frequency raising speed on the premise of ensuring normal oil return of the compressor. For example, the form of the fitting formula and the parameters of the air conditioner may be adjusted based on different application scenarios, for example, the fitting formula may also be v-krn 2+ b, the air speed of the air conditioner can be 4 or 6, the rotating speed of the inner fan corresponding to the lowest air speed can be 400r/min or 600r/min, and the rotating speed of the inner fan corresponding to the highest air speed can be 1400r/min or 1600 r/min. For another example, the opening degree of the electronic expansion valve may be based on the outdoor loopThe corresponding relationship between the ambient temperature or the frequency of the compressor and the opening degree of the electronic expansion valve is adjusted, and the rotating speed of the external fan can be adjusted according to the corresponding relationship between the outdoor ambient temperature and the frequency of the compressor and the rotating speed of the external fan (as shown in the following table 4).
TABLE 4 outer fan speed control table (2)
Wherein, TaoRepresenting the outdoor ambient temperature, f representing the operating frequency of the compressor, rwRepresenting the rotational speed of the outer fan.
In addition, in order to further improve the refrigeration effect of the air conditioner, the frequency-raising stage of the compressor may be further subdivided into a plurality of frequency-raising sub-stages, and correspondingly, each frequency-raising sub-stage includes a fitting sub-formula, and the fitting sub-formulas may only have different coefficients or may have different fitting sub-formulas. For example, the frequency raising stage of the compressor may include three frequency raising sub-stages, and each frequency raising sub-stage corresponds to a fitting sub-formula of v1＝k1rn+b1、v2＝k2rn+b2、v3＝k3rn+b3. After the user determines the wind speed, the control system respectively calculates the frequency raising speed of each frequency raising sub-stage of the corresponding compressor according to each fitting sub-formula, and then controls the compressor to sequentially raise the frequency according to the frequency raising speed of each frequency raising sub-stage. If the relationship of the frequency raising speeds of the three frequency raising sub-stages is calculated as v1>v2>v3(of course, the relationship may be other such as v1<v2<v3Etc.), then through controlling the compressor with the mode that the speed of rising frequency reduces gradually, when realizing the quick refrigeration of air conditioner, guarantee that the compressor oil return is normal, reduce the process noise gradually, increase of service life.
The following briefly describes the operation flow of an air conditioner to which the control method of the present invention is applied, with reference to fig. 1 and 2. The working process of the air conditioner can be as follows:
starting the air conditioner → selecting the refrigeration mode and setting the wind speed to be the maximum wind speed → calculating the raising frequency speed v of the compressor according to the fitting formula, and determining the stable working frequency f according to the table 1, the table 2 and the table 3wTarget opening degree B of expansion valve and rotating speed r of external fanw→ the compressor performs fast frequency raising according to the raising speed v, the expansion valve opens according to the target opening degree B, the external fan rotates according to the rotating speed rwOperation → after a period of time the compressor reaches a stable operating frequency fwThen, the frequency is maintained, the opening degree B of the electronic expansion valve is adjusted according to the table 2, and the rotating speed r of the external fan is adjustedwAdjusted according to table 4.
Finally, although the embodiment is described by taking a cooling mode as an example, it is obvious that such an application scenario is not constant, and those skilled in the art may also apply the control method of the present invention to other modes of an air conditioner, such as a heating mode or a dehumidification mode of an air conditioner, without departing from the principle of the present invention.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
