At present, after the air conditioning equipment is set at a preset temperature by a user, the air conditioning equipment supplies air to the outside according to a preset frequency, and the average temperature of the indoor space is adjusted to the preset temperature within a certain time. In some scenarios, the user needs to adjust the outlet air temperature of the air conditioning device, such as to obtain a cooler or warmer temperature at the outlet relative to a preset temperature, for example, a rapid cooling after a heavy exercise in summer, or a warmer hot air in winter, etc. However, the air conditioning equipment in the related art can only control the average temperature of the indoor space to be consistent with the preset temperature set by the user, and cannot set and adjust the outlet air temperature near the air outlet, so that the requirements of the user on local rapid heating and cooling cannot be met, and the user experience is poor.
In order to solve the technical problem, the present disclosure provides a control method for an air conditioning device, in which a first compressor correction frequency is obtained based on first preset configuration information, a first deviation value and a second deviation value by obtaining set indoor temperature information and target outlet air temperature information, and reference indoor temperature information and reference outlet air temperature information, so as to adjust an operating frequency of a compressor, thereby providing a relatively warmer or cooler area near an air outlet of the air conditioning device, satisfying a demand that a user desires local rapid cooling or heating, and improving user experience.
An exemplary embodiment of the present disclosure provides a control method of an air conditioning apparatus, as shown in fig. 1, including:
s100, acquiring set indoor temperature information and target outlet air temperature information;
s200, acquiring reference indoor temperature information and reference air outlet temperature information, wherein the reference indoor temperature information is the temperature of the indoor environment obtained through detection, and the reference air outlet temperature information is the temperature of the air outlet obtained through detection;
s300, obtaining a first compressor correction frequency according to a first deviation value between set indoor temperature information and reference indoor temperature information and a second deviation value between target outlet air temperature information and reference outlet air temperature information based on first preset configuration information, wherein the first preset configuration information is used for representing the corresponding relation between the first deviation value and the first compressor correction frequency, and the second deviation value and the first compressor correction frequency;
s400, adjusting the running frequency of the compressor based on the first compressor correction frequency.
In step S100, indoor temperature information T is set 1 Is the target average temperature or gear information related to the target average temperature that the air-conditioning apparatus is operated so that the indoor environment in which it is located reaches. Setting indoor temperature information T 1 Typically input by the user is the temperature that the user wishes the indoor environment to reach. Target air-out temperature information T 2 Is an air conditioning deviceProvision is made for the average temperature reached by the local region of the air outlet of the air-conditioning apparatus or for gear information relating to this average temperature. The user may set the temperature information of the air conditioning device through an input device of the air conditioning device, which may be, for example, a remote controller, an application in a terminal device, or the like.

In step S200, the indoor temperature information T is referred to 3 Is the temperature of the indoor environment at the present moment obtained by a detection mode, and refers to the air outlet temperature information T 4 Is the temperature at the air outlet or the area near the air outlet at the current moment obtained by the detection means. Reference indoor temperature information T 3 The temperature sensor on the air conditioning equipment can be used for detecting in real time or at certain preset time intervals, or other temperature sensors arranged indoors can be used for detecting in real time or at certain preset time intervals and then transmitting the detected temperature to the air conditioning equipment. Reference air-out temperature information T 4 May be obtained by real-time detection or successive detection at certain preset intervals by a temperature sensor provided at or near the air outlet of the air conditioning apparatus.
In step S300, the first preset configuration information may be set in the air conditioning equipment when the air conditioning equipment is shipped from a factory, or may be stored in the cloud server, and when the first preset configuration information needs to be used, the first preset configuration information may be retrieved from the cloud server and executed in the air conditioning equipment.
The first preset configuration information is related to the correction frequency of the compressor. The compressor can extract the refrigerant from the low-pressure area, then the refrigerant is compressed and sent to the high-pressure area to be compressed, and the compression speed of the refrigerant in the compressor is adjusted by controlling the module output frequency and voltage of the three-phase induction motor in the compressor, so that the refrigerating or heating speed of the air conditioning equipment is controlled.
According to the set indoor temperature information T 1 With reference to indoor temperature information T 3 A first deviation value delta T1 between, and target outlet air temperature information T 2 And reference air-out temperature information T 4 And obtaining a first compressor correction frequency F by the second deviation value delta T2, wherein the first preset configuration information is used for representing the corresponding relation between the first deviation value delta T1 and the second deviation value delta T2 and the first compressor correction frequency F. That is, the indoor temperature information T can be set based on each detection 1 And reference indoor temperature information T 3 Calculating a first deviation value delta T1 according to the target air outlet temperature information T obtained by each detection 2 And reference air-out temperature information T 4 And the calculated second deviation value delta T2 is used for comparing the first deviation value delta T1 and the second deviation value delta T2 obtained each time with each preset threshold value in the first preset configuration information so as to obtain corresponding first compressor correction frequency F, and on the basis of the current running frequency of the compressor, the first compressor correction frequency F is used for modifying so as to adjust the refrigerating or heating speed of the air conditioning equipment.
For example, the reference indoor temperature information T may be started after the air conditioning apparatus is operated for a certain period of time, for example, 10 minutes, or after the open-loop control is exited 3 And reference air-out temperature information T 4 Detecting and acquiring with reference to indoor temperature information T 3 And reference air-out temperature information T 4 The detection interval time can be once every 3 minutes, so that the first deviation value delta T1 and the second deviation value delta T2 can be obtained in time, whether the air outlet temperature at the current moment meets the requirements of a user or not can be detected in time, the correction frequency F of the first compressor can be adjusted in time, and the use experience of the user is improved.
Here, it should be noted that, in the present embodiment, in order to realize rapid cooling or heating at the air outlet, the frequency of the compressor is adjusted by using the first compressor correction frequency F, and at the same time, a second compressor correction frequency (described in detail later) is calculated according to the set indoor environment temperature and the temperature change rate in the indoor environment, and the operating frequency of the compressor is adjusted by using the second compressor correction frequency. The first compressor correction frequency F and the second compressor correction frequency are used for jointly adjusting the running frequency of the compressors without contradiction, and the first compressor correction frequency F and the second compressor correction frequency can be simultaneously operated or alternately operated.
In some possible embodiments, the first deviation value Δ T1 is the set indoor temperature information T 1 With reference to indoor temperature information T 3 The absolute value of the difference of (a).
Illustratively, the first deviation value Δ T1 is expressed as:
△T1＝|T 1 –T 3 |
since the air conditioning equipment will refer to the indoor temperature information T 3 Adjust to set indoor temperature information T 1 Reaching or approaching the desired indoor temperature information T 1 Then, the frequency of the compressor is automatically adjusted to keep the indoor temperature at the set indoor temperature information T 1 And the phenomenon of supercooling or overheating can not occur. Therefore, in general, when the first deviation value Δ T1 is larger, it indicates that the difference between the indoor environment temperature at the current moment and the indoor environment temperature demanded by the user is larger, and the frequency of the compressor needs to be adjusted, so as to increase the cooling or heating speed of the air conditioning equipment.
In some possible embodiments, when the preset mode is the cooling mode, the second deviation value Δ T2 is the reference outlet air temperature information T 4 And target air-out temperature information T 2 A difference of (d); when the preset mode is the heating mode, the second deviation value Δ T2 is the target outlet air temperature information T 2 And reference air-out temperature information T 4 The difference of (a).
In this embodiment, in the cooling mode, if the second deviation value Δ T2 is a positive value, it means the target outlet air temperature information T 2 Lower than reference air-out temperature information T 4 And the air outlet temperature at the air outlet does not reach the cooling degree required by the user, the first compressor is required to correct the frequency F to adjust the running frequency of the compressor, and the refrigerating speed of the air conditioning equipment is accelerated. In the heating mode, if the second deviation Δ T2 is a positive value, it means the target outlet air temperature information T 2 Higher than reference air-out temperature information T 4 The air outlet temperature at the air outlet is not warm enough, and the first compressor correction frequency F is needed to adjust the operating frequency of the compressor, so that the heating speed of the air conditioning equipment is increased.
In the cooling mode, if the second deviation value Δ T2 is a negative value, it means the target outlet air temperature information T 2 Higher than reference air-out temperature information T 4 When the air outlet temperature at the air outlet exceeds the cooling requirement of the user, the first compressor correction frequency F is needed to adjust the operation frequency of the compressor, so that the refrigeration speed of the air conditioning equipment is reduced. In the heating mode, if the second deviation value Δ T2 is a negative value, it means the target outlet air temperature information T 2 Lower than reference air-out temperature information T 4 The description shows that the outlet air temperature at the outlet is too warm, and the first compressor correction frequency F needs to be used to adjust the operating frequency of the compressor, so as to slow down the heating speed of the air conditioning equipment.
In one example, referring to fig. 2, a control method of the air conditioning apparatus related to the present embodiment will be described in detail:

And at the moment, the air outlet temperature information T is referred to 4 The requirement of the user on local quick cooling and heating is met beyond the warm or cool requirement of the user, so that the existing output frequency of the compressor is kept without adjusting the frequency of the compressor, and the indoor temperature environment can reach the comfortable temperature environment required by the user as soon as possible.
