It should be understood that the data so used may be interchanged under appropriate circumstances such that embodiments of the present disclosure described herein may be made. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover non-exclusive inclusions.
The term "plurality" means two or more unless otherwise specified.
In the embodiment of the present disclosure, the character "/" indicates that the preceding and following objects are in an or relationship. For example, A/B represents: a or B.
The term "and/or" is an associative relationship that describes objects, meaning that three relationships may exist. For example, a and/or B, represents: a or B, or A and B.
The control method for the air conditioner provided by the embodiment of the disclosure is applied to the air conditioner with a quick cooling and/or quick heating mode. Here, through making the setting different from the common mode to the rotating speed of the compressor in the fast cooling or fast heating mode in the air conditioner production and manufacturing process, when the user selects the fast cooling or fast heating mode, the set target temperature is lower than the actual temperature to achieve the fast cooling effect, and the set target temperature is higher than the actual temperature to achieve the fast heating effect.
It should be noted that the rapid cooling or rapid heating mode is only one expression that can represent the cooling or heating effect of the air conditioner, and may have other expressions with similar meanings.
Referring to fig. 1, an embodiment of the present disclosure provides a control method for an air conditioner to implement control of the air conditioner. The control method for the air conditioner includes:
and step S01, acquiring the indoor environment temperature under the condition that the air conditioner compressor runs at the speed exceeding the rated speed, and determining the current initial temperature according to the indoor environment temperature.
Here, the air conditioner compressor is operated above the rated rotating speed to express that the air conditioner is in a working condition of quick heating or quick cooling; the indoor ambient temperature refers to a real-time indoor ambient temperature.
In practical application, the air conditioner compressor can be operated above the rated rotating speed by selecting a quick heating or quick cooling mode of the air conditioner by a user.
Optionally, determining the current initial temperature according to the indoor ambient temperature includes: and acquiring a plurality of indoor environment temperatures collected within a preset time after the compressor runs at the rated speed, and determining one indoor environment temperature as the current initial temperature.
Here, the predetermined time period is used to indicate that the air conditioner enters a fast heating or fast cooling mode and the relevant operation parameters are matched accordingly. The predetermined period of time here may be 0, i.e., the indoor ambient temperature is collected from the moment the compressor is operated above the rated speed.
Therefore, after the air conditioner is determined to be in the quick heating or quick cooling mode, the indoor environment temperature is obtained to serve as the current initial temperature for comparison with the reference temperature in the magnitude relation.
And step S02, acquiring the current set temperature and the current reference temperature of the air conditioner in the current operation mode.
Here, the current operation mode includes, but is not limited to, a cooling mode and a heating mode; the set temperature is the target temperature of the indoor environment of the user set by the user, and the set temperature can be the temperature which is reserved in the memory of the air conditioner and is set by the user last time, can also be set for the first time, and can also be set by the starting at this time.
The current reference temperature is used for expressing the morning and evening of the indoor environment temperature intervening in the running frequency control process of the compressor. In the heating mode, the lower the current reference temperature is, the earlier the indoor environment temperature is involved in the control process of the running frequency of the compressor is represented; in the cooling mode, the higher the current reference temperature is, the earlier the indoor environment temperature is involved in the compressor operation frequency control process.
In the practical application process, the air conditioner operation mode can depend on the operation of a user, and can also be directly judged according to the target temperature of the air conditioner and the indoor environment temperature of the current user. Specifically, when the target temperature is greater than the indoor ambient temperature, the air conditioner is in a heating mode, and when the target temperature is less than the indoor ambient temperature, the air conditioner is in a cooling mode.
And step S03, determining the current temperature difference according to the current set temperature and the current indoor environment temperature.
And step S04, determining a target control mode corresponding to the current operation mode, the current initial temperature, the current reference temperature and the current temperature difference according to the matching relation between the air conditioner operation mode, the initial temperature and the reference temperature, the matching relation between the temperature difference and the first preset value and the corresponding relation between the compressor operation frequency control modes.
Here, the target control manner means a control manner of the operating frequency of the compressor.
The first preset value is an absolute value of a difference between a preset temperature and a temperature when the PID control is started, and if the first preset value is smaller, the PID control is started when the difference between the preset temperature and the current indoor environment temperature is smaller. In practical application, the first preset value can be modified according to practical situations.
And step S05, controlling the running frequency of the compressor according to the target control mode.
In some optional embodiments, a remote controller and a control panel of the air conditioner are provided with a "rapid heating" and/or a "rapid cooling" option, which can be used to trigger the operation of the method flow for controlling the air conditioner in the embodiments of the present disclosure; thus, after the user selects the option of 'fast heating' or 'fast cooling', the air conditioner generates relevant instructions and responds to the execution.
In still other alternative embodiments, the air conditioner may also generate the "rapid heating" or "rapid cooling" command by detecting a trigger, a timing trigger, or the like.
By adopting the control method for the air conditioner provided by the embodiment of the disclosure, under the condition that the air conditioner compressor runs at a speed higher than the rated speed, the target control mode of the air conditioner is determined according to the corresponding relation among the air conditioner running mode, the matching relation between the initial temperature and the reference temperature, the matching relation between the temperature difference and the first preset value and the corresponding relation among the factors of the compressor running frequency control mode, and then the running frequency of the compressor is controlled. The indoor environment temperature is used as the parameter of the control logic of the operation frequency of the air conditioner compressor, the existing control logic for controlling the operation frequency of the compressor according to the outdoor environment temperature is improved, the operation of the air conditioner is more scientific, the effect of quick heating or quick refrigerating is better, and the requirements of a user on quick heating or quick refrigerating in the use process of the air conditioner can be met.

Alternatively, in the case where the matching relationship between the current initial temperature and the current reference temperature is that the current initial temperature is less than or equal to the current reference temperature, the target control manner of the compressor may be determined such that the compressor is operated at the maximum frequency. Therefore, the compressor operates at the maximum frequency, the heating efficiency can be improved, and the difference between the indoor environment temperature and the set temperature can be reduced as soon as possible.
