现有技术中，变频空调器的频率控制逻辑是由室外环境温度决定的，在不同的外部环境温度下，均对应有一个固定频率来控制空调压缩机的运行。然而，这种变频控制方式仅仅考虑外部环境温度因素，使得空调器需要运行一段时间后才能慢慢进入PID控制模式调频，耗费时间较长，调节能力差，且容易在频率调节过程中引起达温停机现象。In the existing technology, the frequency control logic of the inverter air conditioner is determined by the outdoor ambient temperature. Under different external ambient temperatures, there is a corresponding fixed frequency to control the operation of the air conditioner compressor. However, this frequency conversion control method only considers the external environmental temperature factor, so the air conditioner needs to run for a period of time before slowly entering the PID control mode for frequency adjustment, which takes a long time, has poor adjustment ability, and is prone to temperature rise during the frequency adjustment process. shutdown phenomenon.
因此，如何更好地实现空调器的变频控制已成为业界亟待解决的问题。Therefore, how to better realize frequency conversion control of air conditioners has become an urgent problem in the industry.

本申请提供的空调器变频控制方法，通过考虑室内环境温度与用户设定的目标温度之间的温差，增加基于该温差的分段控制逻辑，根据该温差和预设温差阈值分段区间，确定该温差所属的温差阈值区间及对应的目标运行频率确定方式，从而得到空调压缩机的目标运行频率，并控制空调压缩机在目标运行频率下运行，可以实现变频空调器的分段式控制，极大地提升了变频空调器进行频率调节的效率以及稳定性，避免了现有技术中在频率调节过程中容易引起的达温停机现象。The air conditioner frequency conversion control method provided by this application considers the temperature difference between the indoor ambient temperature and the target temperature set by the user, adds segmented control logic based on the temperature difference, and determines the segmented interval based on the temperature difference and the preset temperature difference threshold.

The interval may be an interval greater than the first temperature difference threshold, and the first temperature difference threshold may be 6°C, 8°C, etc.
需要说明的是，由于现有变频空调器频率控制逻辑是由室外环境温度决定的，当室内环境温度与用户设定的温度之间的温差很大，用户需要快速制冷或制热，而室外环境温度使得空调压缩机的运行频率并不高，变频空调器并不能进行快速制冷或制热。It should be noted that since the frequency control logic of the existing inverter air conditioner is determined by the outdoor ambient temperature, when the temperature difference between the indoor ambient temperature and the temperature set by the user is large, the user needs rapid cooling or heating, and the outdoor environment The temperature causes the air conditioning compressor to run less frequently, and the inverter air conditioner cannot perform rapid cooling or heating.
在本实施例中，可以直接计算室内环境温度与用户设定的目标温度之间的温差，在该温差包含于预设温差阈值分段区间中的第二温差阈值区间的情况下，说明该温差很大，用户需要进行快速制冷或制热，由此，可以 根据第二温差阈值区间对应的目标运行频率的确定方式，直接确定目标运行频率为空调压缩机的最大频率，即此时将空调压缩机调节至最大频率运行。In this embodiment, the temperature difference between the indoor ambient temperature and the target temperature set by the user can be directly calculated. If the temperature difference is included in the second temperature difference threshold interval in the preset temperature difference threshold segment interval, the temperature difference is explained. is very large, the user needs to perform rapid cooling or heating. Therefore, according to the determination method of the target operating frequency corresponding to the second temperature difference threshold interval, the target operating frequency can be directly determined to be the maximum frequency of the air conditioner compressor, that is, the air conditioner will be compressed at this time.

本申请实施例所描述的目标固定频率指的是空调器预先设定的基于室外环境温度确定的空调压缩机运行频率。例如，空调器制热时，室外环境温度在5℃至10℃，空调压缩机对应在一个固定频率运行；室外环境温度0℃至5℃，空调压缩机对应在另一个固定频率运行。The target fixed frequency described in the embodiment of this application refers to the air conditioning compressor operating frequency preset by the air conditioner and determined based on the outdoor ambient temperature. For example, when the air conditioner is heating, when the outdoor ambient temperature is 5°C to 10°C, the air conditioner compressor runs at a fixed frequency; when the outdoor ambient temperature is 0°C to 5°C, the air conditioner compressor runs at another fixed frequency.
本申请实施例所描述的目标频率变化阈值可以根据所属温差阈值区间的温差阈值大小设定，也就是说，温差阈值较大的温差阈值区间对应的目标频率变化阈值可以设定大一些，温差阈值较小的温差阈值区间对应的目标频率变化阈值可以设定小一些。例如，第一温差阈值区间为2℃～4℃时，目标频率变化阈值可以取值为5Hz、6Hz、7Hz等；第一温差阈值区间为4℃～6℃时，目标频率变化阈值可以取值为10Hz、11Hz、12Hz等，本申请实施例中对此不做具体限定。The target frequency change threshold described in the embodiments of this application can be set according to the temperature difference threshold value of the temperature difference threshold interval to which it belongs. That is to say, the target frequency change threshold value corresponding to the temperature difference threshold interval with a larger temperature difference threshold value can be set larger, and the temperature difference threshold value can be set larger. The target frequency change threshold corresponding to a smaller temperature difference threshold interval can be set smaller. For example, when the first temperature difference threshold interval is 2°C to 4°C, the target frequency change threshold can be 5Hz, 6Hz, 7Hz, etc.; when the first temperature difference threshold interval is 4°C to 6°C, the target frequency change threshold can be a value of 5Hz, 6Hz, 7Hz, etc. It is 10Hz, 11Hz, 12Hz, etc., which is not specifically limited in the embodiments of this application.

示例性地，在本实施例中，当第一温差阈值取值为6℃，第一温差阈值区间可以取值为0℃～2℃，2℃～4℃，或4℃～6℃，那么第一阈值子区间可以是2℃～4℃，或4℃～6℃。For example, in this embodiment, when the first temperature difference threshold is 6°C, the first temperature difference threshold interval can be 0°C to 2°C, 2°C to 4°C, or 4°C to 6°C, then The first threshold sub-interval may be 2°C to 4°C, or 4°C to 6°C.

在本申请实施例中，目标频率变化阈值可以根据所属温差阈值区间的温差阈值大小设定，如第一阈值子区间为2℃～4℃时，目标频率变化阈值可以为5Hz；第一阈值子区间为4℃～6℃时，目标频率变化阈值可以为10Hz；In this embodiment of the present application, the target frequency change threshold can be set according to the temperature difference threshold of the temperature difference threshold interval to which it belongs. For example, when the first threshold sub-interval is 2°C to 4°C, the target frequency change threshold can be 5 Hz; When the interval is 4℃~6℃, the target frequency change threshold can be 10Hz;
也就是说，在室内环境温度与用户设定的目标温度之间的温差包含于第一阈值子区间如2℃～4℃的情况下，根据第一阈值子区间对应的目标运行频率确定方式，第一运行频率可以基于目标固定频率与目标频率变化阈值求和得到，如目标固定频率为30Hz，目标频率变化阈值为5Hz，则此时第一运行频率为35Hz，由此，可以确定空调压缩机的目标运行频率为35Hz；That is to say, when the temperature difference between the indoor ambient temperature and the target temperature set by the user is included in the first threshold sub-interval, such as 2°C to 4°C, according to the target operating frequency determination method corresponding to the first threshold sub-interval, The first operating frequency can be obtained based on the sum of the target fixed frequency and the target frequency change threshold. For example, the target fixed frequency is 30Hz and the target frequency change threshold is 5Hz. Then the first operating frequency is 35Hz at this time. From this, the air conditioning compressor can be determined The target operating frequency is 35Hz;
在室内环境温度与用户设定的目标温度之间的温差包含于第一阈值子区间如4℃～6℃的情况下，如目标固定频率为30Hz，目标频率变化阈值为10Hz，则此时第一运行频率为40Hz，可以确定空调压缩机的目标运行频率为40Hz。在确定空调压缩机的目标运行频率之后，可以控制空调压缩机在目标运行频率下运行。When the temperature difference between the indoor ambient temperature and the target temperature set by the user is included in the first threshold sub-interval, such as 4°C to 6°C, if the target fixed frequency is 30Hz and the target frequency change threshold is 10Hz, then at this time, the If the operating frequency is 40Hz, it can be determined that the target operating frequency of the air conditioning compressor is 40Hz. After the target operating frequency of the air conditioning compressor is determined, the air conditioning compressor can be controlled to operate at the target operating frequency.

本申请实施例所描述的第二运行频率指的是基于目标固定频率与目标频率变化阈值的差值得到的，其用于在室内环境温度与用户设定的目标温度之间的温差包含于第二阈值子区间的情况下，控制空调压缩机的运行。The second operating frequency described in the embodiment of this application is obtained based on the difference between the target fixed frequency and the target frequency change threshold, which is used when the temperature difference between the indoor ambient temperature and the user-set target temperature is included in the first In the case of two threshold sub-intervals, the operation of the air conditioning compressor is controlled.
在本申请实施例中，目标频率变化阈值可以根据所属温差阈值区间的温差阈值大小设定，如第二阈值子区间为0℃～2℃时，目标频率变化阈值可以为5Hz；In the embodiment of the present application, the target frequency change threshold can be set according to the temperature difference threshold of the corresponding temperature difference threshold interval. For example, when the second threshold sub-interval is 0°C to 2°C, the target frequency change threshold can be 5Hz;
也就是说，在室内环境温度与用户设定的目标温度之间的温差包含于第二阈值子区间如0℃～2℃的情况下，根据第二阈值子区间对应的目标运行频率确定方式，第二运行频率可以基于目标固定频率与目标频率变化阈值的差值得到，如目标固定频率为50Hz，目标频率变化阈值为5Hz，则此时第二运行频率为45Hz，由此，可以确定空调压缩机的目标运行频率为45Hz，控制空调压缩机在45Hz运行。That is to say, when the temperature difference between the indoor ambient temperature and the target temperature set by the user is included in the second threshold sub-interval, such as 0°C to 2°C, according to the target operating frequency determination method corresponding to the second threshold sub-interval, The second operating frequency can be obtained based on the difference between the target fixed frequency and the target frequency change threshold. For example, the target fixed frequency is 50Hz and the target frequency change threshold is 5Hz. At this time, the second operating frequency is 45Hz. From this, the air conditioner compression can be determined The target operating frequency of the machine is 45Hz, and the air conditioning compressor is controlled to run at 45Hz.
在本申请实施例中，当检测到室内环境温度与用户设定的目标温度之间的温差较小时，在原有基于室外环境温度决定的目标固定频率的基础上，进一步减小空调压缩机的运行频率，有利于空调器平稳地进入PID控制模式，极大地提升了变频空调器进行频率调节的效率以及稳定性，可以避免 现有技术中容易引起的达温停机现象。In the embodiment of the present application, when the temperature difference between the indoor ambient temperature and the target temperature set by the user is detected to be small, the operation of the air conditioning compressor is further reduced based on the original target fixed frequency determined based on the outdoor ambient temperature. The frequency is conducive to the smooth entry of the air conditioner into the PID control mode, which greatly improves the efficiency and stability of the frequency adjustment of the inverter air conditioner, and can avoid the temperature shutdown phenomenon that is easily caused in the existing technology.
由此，在确定室内环境温度与用户设定的目标温度之间的温差包含于预设温差阈值分段区间中的第一温差阈值区间的情况下，根据第一温差阈值区间对应的目标运行频率确定方式，可以确定出空调压缩机的目标运行频率，进而可以控制空调器压缩机在目标运行频率下运行，实现对变频空调器的分段式控制。Therefore, when it is determined that the temperature difference between the indoor ambient temperature and the target temperature set by the user is included in the first temperature difference threshold interval among the preset temperature difference threshold segmented intervals, the target operating frequency corresponding to the first temperature difference threshold interval is The determination method can determine the target operating frequency of the air conditioner compressor, and then control the air conditioner compressor to operate at the target operating frequency, thereby achieving segmented control of the inverter air conditioner.
本申请实施例的方法，通过在原有室外环境温度调频方式的基础上，设定多段温差阈值区间的调控区间，针对实际室内环境温度与用户设定的目标温度之间的温差，动态确定空调压缩机的目标运行频率，实现分段式控制变频空调器的调频过程，有利于提升变频空调器进行频率调节的效率以及稳定性。The method of the embodiment of the present application dynamically determines the air conditioner compression based on the temperature difference between the actual indoor ambient temperature and the target temperature set by the user by setting a multi-section temperature difference threshold interval based on the original outdoor ambient temperature frequency modulation method. The target operating frequency of the inverter air conditioner is realized in a segmented manner to control the frequency adjustment process of the inverter air conditioner, which is conducive to improving the efficiency and stability of the frequency adjustment of the inverter air conditioner.
基于上述实施例的内容，作为一种可选的实施例，基于该温差和预设温差阈值分段区间，确定空调压缩机的目标运行频率，包括：Based on the contents of the above embodiments, as an optional embodiment, determining the target operating frequency of the air conditioning compressor based on the temperature difference and the preset temperature difference threshold segment interval includes:

在PID控制模式下，确定空调压缩机的目标运行频率。In PID control mode, determine the target operating frequency of the air conditioning compressor.
具体地，本申请实施例所描述的第三温差阈值区间可以是预设温差阈值分段区间的连续多段温差阈值区间中，表征室内环境温度与用户设定的目标温度之间的温差为负值的阈值区间，其可以为小于第二温差阈值的区间，即第二温差阈值为0℃。Specifically, the third temperature difference threshold interval described in the embodiment of the present application may be a continuous multiple temperature difference threshold interval of preset temperature difference threshold segment intervals, indicating that the temperature difference between the indoor ambient temperature and the target temperature set by the user is a negative value. The threshold interval may be an interval smaller than the second temperature difference threshold, that is, the second temperature difference threshold is 0°C.
在本实施例中，在确定室内环境温度与用户设定的目标温度之间的温差为负值，即该温差包含于预设温差阈值分段区间中的第三温差阈值区间的情况下，可以控制空调器直接进入PID控制模式；通过在PID控制模式下，基于PID控制原理，计算空调压缩机的目标运行频率，动态调节空调压缩机的运行频率，控制变频空调器的运行。In this embodiment, when it is determined that the temperature difference between the indoor ambient temperature and the target temperature set by the user is a negative value, that is, the temperature difference is included in the third temperature difference threshold interval in the preset temperature difference threshold segmented interval, it can be Control the air conditioner to directly enter the PID control mode; in the PID control mode, based on the PID control principle, calculate the target operating frequency of the air conditioning compressor, dynamically adjust the operating frequency of the air conditioning compressor, and control the operation of the inverter air conditioner.
本申请实施例的方法，通过考虑实际室内环境温度与用户设定的目标温度之间的温差，在该温差为负值时控制变频空调器进入PID控制模式，可以更加有效地实现变频空调器平稳过渡到PID控制。The method of the embodiment of the present application considers the temperature difference between the actual indoor ambient temperature and the target temperature set by the user, and controls the inverter air conditioner to enter the PID control mode when the temperature difference is negative, which can more effectively achieve the stability of the inverter air conditioner. Transition to PID control.
可选地，在本申请的一个具体实施例中，通过检测室外环境温度，来确定空调压缩机的初始运行频率，进而通过检测室内环境温度与用户设定 的目标温度之间的温差，若该温差在第二温差阈值区间上，即该温差大于6℃，则控制空调压缩机以最大频率运行；Optionally, in a specific embodiment of the present application, the initial operating frequency of the air conditioning compressor is determined by detecting the outdoor ambient temperature, and then by detecting the temperature difference between the indoor ambient temperature and the target temperature set by the user. If the If the temperature difference is within the second temperature difference threshold interval, that is, the temperature difference is greater than 6°C, the air conditioning compressor is controlled to run at the maximum frequency;
若该温差在第一温差阈值区间中的第一阈值子区间4℃～6℃上，则在初始运行频率的基础上加上10HZ，以此确定空调压缩机的第一运行频率；若该温差在第一温差阈值区间中的第一阈值子区间2℃～4℃之间，则在初始运行频率的基础上加上5HZ，以此确定空调压缩机的第一运行频率；If the temperature difference is within the first threshold sub-interval of 4°C to 6°C in the first temperature difference threshold interval, then 10HZ is added to the initial operating frequency to determine the first operating frequency of the air conditioning compressor; if the temperature difference In the first threshold sub-interval of the first temperature difference threshold interval between 2°C and 4°C, 5HZ is added to the initial operating frequency to determine the first operating frequency of the air conditioning compressor;
若该温差在第一温差阈值区间中的第二阈值子区间0℃～2℃上，则在初始运行频率的基础上减去5HZ，以此确定空调压缩机的第二运行频率；If the temperature difference is within the second threshold sub-interval of 0°C to 2°C in the first temperature difference threshold interval, then 5HZ is subtracted from the initial operating frequency to determine the second operating frequency of the air conditioning compressor;
若该温差在第三温差阈值区间上，即该温差低于0℃，则控制空调器直接进入PID控制模式进行调频。If the temperature difference is within the third temperature difference threshold interval, that is, the temperature difference is lower than 0°C, the air conditioner is controlled to directly enter the PID control mode for frequency modulation.
需要说明的是，在本实施例中，在空调器制热时，室内环境温度与用户设定的目标温度之间的温差通过用户设定的目标温度减去室内环境温度得到；在空调器制冷时，室内环境温度与用户设定的目标温度之间的温差通过室内环境温度减去用户设定的目标温度得到。It should be noted that in this embodiment, when the air conditioner is heating, the temperature difference between the indoor ambient temperature and the target temperature set by the user is obtained by subtracting the indoor ambient temperature from the target temperature set by the user; when the air conditioner is cooling When , the temperature difference between the indoor ambient temperature and the user-set target temperature is obtained by subtracting the user-set target temperature from the indoor ambient temperature.
现有变频空调器的控制方法仅考虑了室外环境温度的情况，不能满足不同用户的需求，若同一地区的两个用户，一个设定了较高温度，另一个设定了较低温度，但是空调器却以同一频率运行，其中一个用户的需求势必需要耗费更长的时间才能达到，由此不能满足二者不同的需求，用户体验不佳。The existing control method of inverter air conditioners only considers the outdoor ambient temperature and cannot meet the needs of different users. If there are two users in the same area, one sets a higher temperature and the other sets a lower temperature, but However, the air conditioner runs at the same frequency, so it will take longer to meet the needs of one user. Therefore, the different needs of the two cannot be met, and the user experience is poor.
通过本申请实施例的方法，一方面可以满足用户的不同需求，当用户设定温度与室内温度温差较大时，加速制冷或制热；另一方面可以实现分段式控制，随着室内温度与设定温度接近，频率逐渐降低，寻求稳态频率控制，不容易造成达温停机的现象。Through the methods of the embodiments of this application, on the one hand, the different needs of users can be met. When the temperature difference between the user's set temperature and the indoor temperature is large, cooling or heating can be accelerated; on the other hand, segmented control can be achieved, and as the indoor temperature changes, When the temperature is close to the set temperature, the frequency gradually decreases to seek steady-state frequency control, which will not easily cause shutdown when the temperature reaches temperature.
