发明人所知晓的相关技术中，为空调机组设置了最高运行频率，以防止室外风机无上限的增大运行频率，导致空调机组的风叶或者电机损坏。通常最高运行频率为固定值，不可改变。然而，在空调机组的风机持续高频运行时产生的噪音是多联室外机 噪音的主要来源之一。风机长时间的持续高频运行，其产生的噪音可能会对用户的生活、休息等造成影响。
有鉴于此，本公开的实施例提供了一种运行频率的调节方法和装置，以至少解决空调机组长时间持续高频运行产生噪音较大的技术问题。
在本公开的实施例中，采用对空调机组的当前最高运行频率进行修正的方式，在获取到空调机组的当前运行状态之后，在检测到当前运行状态与预设时长内空调机组的历史运行状态相匹配的情况下，确定噪音修正值，然后根据噪音修正值以及第一最高运行频率确定空调机组的当前最高运行频率，并根据当前最高运行频率调节空调机组的当前运行频率。
容易注意到的是，空调机组的历史运行状态表征了用户的使用习惯。在本公开中，根据用户的使用习惯来智能化调节空调机组的运行频率，保证了用户使用空调机组的舒适性。另外，根据用户的使用习惯来确定噪音修正值，并根据修正值来确定空调机组的当前最高运行频率，进而根据当前最高运行频率调节空调机组的当前运行频率，可以降低空调机组运行时所产生的噪音，减少噪音对用户的工作、生活等的影响。
由此可见，本公开所提供的方案达到了控制空调机组的运行频率的目的，从而实现了降低空调机组所产生的噪音的技术效果，进而解决了空调机组长时间持续高频运行产生噪音较大的技术问题。
根据本公开实施例，提供了一种运行频率的调节方法，需要说明的是，在附图的流程图示出的步骤可以在诸如一组计算机可执行指令的计算机系统中执行，并且，虽然在流程图中示出了逻辑顺序，但是在某些情况下，可以以不同于此处的顺序执行所示出或描述的步骤。
图1是本公开实施例的运行频率的调节方法流程图，如图1所示，该方法包括如下步骤：
步骤S102，获取空调机组的当前运行状态。
需要说明的是，空调机组的当前运行状态包括但不限于空调机组的运行模式、空调机组的开机数量以及空调机组的当前运行频率等，其中，空调机组的运行模式包括但不限于制冷模式和制热模式。
在一些实施例中，上述空调机组为多联机系统中的空调机组，多联机系统具有数据采集设备，数据采集设备可获取到空调机组的当前运行状态。例如，数据采集设备可以检测空调机组的运行模式，并采集空调机组的当前运行频率。
步骤S104，在检测到当前运行状态与预设时长内空调机组的历史运行状态相匹配的情况下，确定噪音修正值。
在步骤S104中，空调机组的历史运行状态表征了用户使用空调机组的使用习惯，在一些实施例中，预设时长为与当前时间相差预设时长的时间点到当前时间的时间段，例如，预设时长为24小时。
另外，噪音修正值用于对空调机组的当前最高运行频率进行修正，其中，当前最高运行频率为空调机组可运行的最高运行频率。例如，多联机系统中的处理器根据停机的室内机容量以及开机容量来计算上述噪音修正值，其中，停机的室内机容量表征温度达到预设温度时出现停机的室内机容量。
此外，还需要说明的是，确定当前运行状态与预设时长内空调机组的历史运行状态相匹配，可以保证用户的舒适性。而在确定当前运行状态与预设时长内空调机组的历史运行状态相匹配的情况下，才确定噪音修正值对空调机组的当前最高运行频率进行修正，进而通过修正降低空调机组的风机运行时所产生的噪音，不仅保证了用户的舒适性，还减少了噪音对用户的影响。
步骤S106，根据噪音修正值以及第一最高运行频率确定空调机组的当前最高运行频率。
在一些实施例中，上述第一最高运行频率为空调机组在预设时长内的最高运行频率，例如，当前时间为12点，则第一最高运行频率为昨天12点至当前时间的24小时内，空调机组的风机的最高运行频率。
步骤S108，根据当前最高运行频率调节空调机组的当前运行频率。
在确定了空调机组的当前最高运行频率之后，处理器根据对空调机组的当前运行频率进行调节。
具体的，处理器检测空调机组的当前运行频率是否大于当前最高运行频率，如果检测到空调机组的当前运行频率大于当前最高运行频率，则控制空调机组按照当前最高运行频率运行。由此可见，步骤S108可以控制空调机组的当前运行频率不会超过当前最高运行频率，从而达到了降低空调机组的风机的运行频率的目的，进而实现了减少空调机组的风机长时间高频运行所产生的噪音。
基于上述步骤S102至步骤S108所限定的方案，可以获知，采用对空调机组的当前最高运行频率进行修正的方式，在获取到空调机组的当前运行状态之后，在检测到当前运行状态与预设时长内空调机组的历史运行状态相匹配的情况下，确定噪音修正 值，然后根据噪音修正值以及第一最高运行频率确定空调机组的当前最高运行频率，并根据当前最高运行频率调节空调机组的当前运行频率。
容易注意到的是，空调机组的历史运行状态表征了用户的使用习惯。本公开的实施例根据用户的使用习惯智能化调节空调机组的运行频率，保证了用户使用空调机组的舒适性。另外，根据用户的使用习惯来确定噪音修正值，并根据修正值来确定空调机组的当前最高运行频率，进而根据当前最高运行频率调节空调机组的当前运行频率，可以降低空调机组运行时所产生的噪音，减少噪音对用户的工作、生活等的影响。
由此可见，本公开的实施例通过控制空调机组的运行频率的目的，能够降低空调机组所产生的噪音，从而解决了空调机组长时间持续高频运行产生噪音较大的技术问题。
在一些实施例中，在获取空调机组的当前运行状态之前，空调机组的处理器检测空调机组是否开机，并在检测到空调机组处于开机状态的情况下，获取空调机组的开机数量以及环境参数，然后根据开机数量以及环境参数在历史数据库中确定最优历史运行数据，并控制空调机组按照最优历史运行数据运行。其中，上述环境参数包括但不限于天气参数，例如，环境温度、湿度和风速等。
容易注意到的是，最优历史运行数据表征了空调机组以该运行数据运行时，用户的舒适度体验效果最好。因此，当空调机组开机运行时，根据空调机组的开机数量、天气参数等条件，首先在历史数据库中匹配最优历史运行数据，使得空调机组按照历史运行最优数据运行，可以提高用户的舒适度体验。
需要说明的是，上述最优历史运行数据可以为处理器对用户使用空调机组的使用习惯进行记录学习所得到的运行数据，也可以为对互联网中的相关数据进行机器学习以及智能分析所得到的空调机组的运行数据。
在一些实施例中，多联机系统对应的处理器还对用户的使用习惯(即空调机组的历史运行状态)进行定义。具体的，处理器首先获取第一预设时长内空调机组每天都开机的第一开机数量，以及第一预设时长内开启过的空调机组的第二开机数量，并获取连续第二预设时长内每天最多开启的空调机组的第三开机数量，以及第二预设时长内开启过的空调机组的第四开机数量。然后计算第一开机数量与第二开机数量的比值，得到第一比值，以及计算第三开机数量与第四开机数量的比值，得到第二比值。最后根据第一比值与第三阈值的关系，以及第二比值与第四阈值的关系确定空调机组的历史运行状态。
例如，定义用户使用习惯1为：连续X天(即第一预设时长)内在同一种运行模式(例如，制冷模式)下每天都会开机的室内机的数量(即第一开机数量)和在相同日期(即连续X天)内所有开启过的室内机的数量(即第二开机数量)的比值(即第一比值)大于等于M(即第三阈值)，且连续Y天(即第二预设时长)内每天都会开启的室内机的开启数量(即第三开机数量)与开启过的室内机的数量(即第四开机数量)的比值(即第二比值)大于等于N1(即第四阈值)；
定义用户使用习惯2为：连续X天内在同一种运行模式下每天都会开机的室内机的数量和在相同日期内所有开启过的室内机的数量的比值≥M，且N1≥连续Y天内每天最多的内机开启数量与所有室内机的数量比值≥N2；
定义用户使用习惯n为：连续X天内在同一种运行模式下每天都会开机的室内机的数量和在相同日期内所有开启过的室内机的数量的比值≥M，且Nn-1≥连续Y天内每天最多的内机开启数量与所有室内机的数量比值≥Nn；
如上述举例所示，处理器可根据不同的条件，定义多种不同的用户使用习惯。
在一些实施例中，在检测到当前运行状态与预设时长内空调机组的历史运行状态相匹配的情况下，处理器确定噪音修正值。具体的，处理器首先检测当前运行状态是否满足舒适性控制条件，其中，舒适性控制条件为满足用户舒适性需求的空调机组的运行参数，然后，在检测到当前运行状态满足舒适性控制条件的情况下，根据第一预设时长内停机的室内机容量与开机容量的比值确定第一修正值，并在第一修正值大于等于第一阈值的情况下，确定第一阈值为噪音修正值，在第一修正值小于第一阈值的情况下，确定第一修正值为噪音修正值，其中，停机的室内机容量表征温度达到预设温度时出现停机的室内机容量。
在检测到当前运行状态不满足舒适性控制条件的情况下，根据第一预设时长内停机的室内机容量与开机容量的比值确定第二修正值，并在第二修正值小于等于第一阈值的情况下，确定第一阈值为噪音修正值；在第二修正值大于第一阈值的情况下，确定第二修正值为噪音修正值。
在一些实施例中，噪音修正值满足下式：
噪音修正值＝(0.75-第一预设时长内停机的室内机容量/第一预设时长内室内机的开机容量)*当前机组风机最高运行频率*K
在上式中，第一预设时长内停机的室内机容量可以为过去24小时内出现过的温度达到预设温度时室内机停机的总容量，第一预设时长内室内机的开机容量可以为过 去24h内总开机室内机容量，K为系数。
在检测到用户对空调机组的当前使用状态和过去24h的使用习惯相符时，处理器进一步判断空调机组的当前运行状态是否满足温度舒适性运行条件，如果满足，则进一步计算第一修正值；如果不满足，则进一步计算第二修正值。
在一些实施例中，在计算得到噪音修正值之后，处理器对第一修正值进行负向寻优，即对负值优先选取，例如，如果第一修正值大于0，则噪音修正值的取值为0；如果第一修正值小于等于0，则噪音修正值的取值为第一修正值。处理器对第二修正值进行正向寻优，即对正值优先选取，例如，如果第二修正值小于0，则噪音修正值的取值为0；如果第二修正值大于等于0，则噪音修正值的取值为第二修正值。
通过对第一修正值进行负向寻优保证了用户的噪音体验，对第二修正值进行正向寻优保证了用户的舒适性体验。
在一种可选的实施例中，舒适性控制条件包括温度舒适性条件和噪音舒适性条件，其中，温度舒适性条件的优先级大于噪音舒适性条件。需要说明的是，温度舒适性条件是指空调机组的运行参数是否满足用户对温度舒适性的要求，噪音舒适性条件是指空调机组的运行参数是否满足用户对噪音舒适性的要求。其中，在空调机组处于制冷模式的情况下，温度舒适性条件包括如下条件中的至少一个：系统低压处于预设低压范围内，以及室内机的进管温度和出管温度中的至少一个处于预设温度范围内，例如，当空调机组制冷运行时，检测空调机组的系统低压以及室内机的进管温度和出管温度中的至少一个，如果系统低压达到预设低压范围，并且，室内机的进管温度处于第一温度范围内，出管温度处于第二温度范围内，则确定满足温度舒适性条件；在空调机组处于制热模式的情况下，温度舒适性条件包括如下条件中的至少一个：系统高压处于预设高压范围内，以及室内机的进管温度和出管温度中的至少一个处于预设温度范围内，例如，空调当机组制热运行时，检测系统高压以及室内机的进管温度和出管温度中的至少一个，若系统高压达到预设高压范围，并且，室内机的进管温度处于第一温度范围内，出管温度处于第二温度范围内，则确定满足温度舒适性条件。
在一些实施例中，在确定了噪音修正值之后，处理器根据噪音修正值以及第一最高运行频率确定空调机组的当前最高运行频率。具体的，在检测到当前运行状态满足舒适性控制条件的情况下，获取第一最高运行频率与第二最高运行频率中较小的频率作为第一运行频率，并根据噪音修正值对第一运行频率进行修正，得到当前最高运行频率，其中，第二最高运行频率为空调机组在历史最优运行数据中的最高运行频率； 在检测到当前运行状态不满足舒适性控制条件的情况下，获取第一最高运行频率与第二最高运行频率中较大的频率作为第二运行频率，并根据噪音修正值对第二运行频率进行修正，得到当前最高运行频率。
在一些实施例中，空调机组的当前最高运行频率满足下式：
当前最高运行频率＝F(第一最高运行频率，第二最高运行频率)+噪音修正值
在上式中，第一最高运行频率可以为过去24小时内空调机组的风机的最高运行频率，第二最高运行频率为历史最优运行数据中风机的最高运行频率。其中，在检测到当前运行状态满足舒适性控制条件的情况下，F(第一最高运行频率，第二最高运行频率)的值取第一最高运行频率和第二最高运行频率中的较小值；在检测到当前运行状态不满足舒适性控制条件的情况下，F(第一最高运行频率，第二最高运行频率)的值取第一最高运行频率和第二最高运行频率中的较大值。
在一些实施例中，图2示出了上式的运行频率的调节方法的流程图，具体的，首先通过大数据手段分析并总结出用户使用空调机组的使用规律，并根据使用规律确定用的使用习惯，即得到空调机组的历史运行状态。然后在空调机组开机时，获取空调机组的当前运行状态，并从数据库中匹配到历史最优运行数据，使空调机组按照历史最优运行数据运行，进而保证了用户的舒适度。在一些实施例中，多联机系统的处理器检测空调机组的当前运行状态，并判断空调机组的当前运行状态是否符合过去24小时的用户使用习惯，如果符合，则进一步检测空调机组的当前运行状态是否满足温度舒适性条件，如果满足，则计算第一修正值，并对第一修正值进行负向寻优；如果不满足，则计算第二修正值，并对第二修正值进行正向寻优。通过对第一修正值进行负向寻优，或对第二修正值进行正向寻优，可以得到噪音修正值。最后，根据噪音修正值以及过去24小时的最高运行频率计算出当前最高运行频率。
需要说明的是，在上述过程中，如果空调机组的当前运行状态不符合过去24小时的用户使用习惯，则空调机组按照用户输入的控制指令正常运行。
在一些实施例中，本公开还提供了更加简洁的空调机组的运行频率的处理方法，如图3所示，当噪音自适应功能有效时，通过判断用户的使用习惯与预定义使用习惯是否相同来对空调机组的风机的运行频率进行修正，以降低室外机运行时产生的噪音。具体的，用户设置空调机组的噪音自适应控制功能有效。然后采用上述实施例所介绍的方法定义用户使用空调机组的使用习惯，并检测空调机组当前的运行状态，并判断空调机组当前的运行状态是否和过去24小时内用户的使用习惯相符。如果是， 则多联机系统的处理器计算确定噪音修正值。
具体的，处理器根据第一预设时长内停机的室内机容量与开机容量的比值确定第一修正值，然后在第一修正值大于等于第一阈值的情况下，确定第一阈值为噪音修正值；在第一修正值小于第一阈值的情况下，确定第一修正值为噪音修正值。可选的，
噪音修正值满足下式：
噪音修正值＝(0.75-第一预设时长内停机的室内机容量/第一预设时长内室内机的开机容量)*当前机组风机最高运行频率*F
在上式中，第一预设时长内停机的室内机容量可以为过去24小时内出现过的温度达到预设温度时室内机停机的总容量，第一预设时长内室内机的开机容量可以为过去24h内总开机室内机容量，F为系数，该系数为根据环境温度所确定的预设值。另外，上述空调机组的风机的运行频率最大不能超过预设值a。
在一些实施例中，如图3所示，在确定了噪音修正值之后，处理器根据噪音修正值以及过去24小时的最高运行频率计算出当前最高运行频率。其中，处理器使用噪音修正值对第一最高运行频率进行修正，得到空调机组的当前最高运行频率。然后，处理器检测空调机组的当前运行状态。在当前运行状态满足预设条件的情况下，控制空调机组的风机正常运行，即空调机组按照用户输入的控制指令正常运行，退出该控制。其中，预设条件包括如下至少之一：空调机组出现保护；空调机组存在保护风险；空调机组的运行参数达到预设阈值；和空调机组的当前运行状态与预设时长内空调机组的历史运行状态不匹配。
需要说明的是，当空调机组的运行参数大于第一阈值时，空调机组出现保护而停机，例如，空调机组的系统高压对应的温度值高于65℃，则空调机组出现保护。当空调机组的运行参数处于预设范围内时，则确定空调机组存在保护风险，例如，检测到空调机组的系统高压对应的温度值为63℃，还未达到空调机组保护停机的第一阈值时，则确定空调机组出现保护风险。另外，上述预设阈值为能够使空调机组正常运行的参数。
由上可知，本公开所提供的上述方案根据用户使用习惯，智能化调节空调机组的风机的运行频率，在保证用户使用舒适性的同时，尽可能降低风机运行时产生的噪音，减少噪音对用户的工作、生活等造成影响。
