技术领域
本申请涉及空调技术领域，例如涉及一种空调的控制方法、控制装置和空调。
背景技术
目前，空调通常采用比例-积分-微分(Proportion Integral Differential，PID)控制算法实现室内温度控制，在PID控制算法中，实际室内温度与设定室内温度的温度差值越大，则空调压缩机的运行频率越大，空调的制冷能力/制热能力越强，越容易比较快速地使实际室内温度达到设定室内温度，以消除温度差值；并且，在温度差值在死区温度范围内的情况下，空调停止运行。
在实现本申请实施例的过程中，发现相关技术中至少存在如下问题：
在空调停止运行后，室内空间与外界仍继续热交换，导致实际室内温度与设定室内温度的温度差值超出死区温度范围，即，室内温度出现波动，而该温度波动会导致空调继续运行，并在实际室内温度与设定室内温度的温度差值再次进入死区温度范围的情况下，空调再停止运行，这样空调反复起停，并伴随室内温度波动，降低了用户的温度体验。

在空调的常规控制过程中，如果设定室内温度与实际室内温度的温度差值过大，则空调的实际制冷能力或实际制热能力比较高，如果设定室内温度和实际室内温度的温度差值较小，则空调的实际制冷能力或制热能力较弱，甚至停机。
在本申请实施例提供的空调的控制方法中，在设定室内温度和实际室内温度的温度差值较小的情况下，记录实际室内温度将要达到设定室内温度至达到设定温度时所需的时长，并依据该时长重新确定压缩机频率以及风机转速，依据重新确定的压缩机频率和风机转速控制空调，在实际室内温度达到设定室内温度的过程中，使空调实现不停机地运行，以避免空调启停导致的实际室内温度的波动，提高实际室内温度的稳定性，提高用户的温度体验。
当然，在设定室内温度和实际室内温度较大的情况下，本申请实施例对空调的制冷控制过程或制热控制过程不做具体限定，可以是常规的PID控制方法，可以是其他现有技术中的控制方法。
以下对本申请实施例提供的空调的控制方法进行具体说明：
图1是本申请实施例提供的一种空调的控制方法的流程示意图，该空调的控制方法可通过空调的控制器执行。结合图1所示，空调的控制方法包括：
S101、获得第一实际室内温度。
这里的获得第一实际室内温度，指的是在空调的调节作用下，实际室内温度趋近设定室内温度且达到设定室内温度之前，获得第一实际室内温度。
例如在空调处于制热过程中，实际室内温度低于设定室内温度，且实际室内温度从未达到过(大于或等于)设定室内温度的情况，即为实际室内温度趋近设定室内温度且达到设定室内温度之前的情况。
或者，在空调处于制冷过程中，实际室内温度高于设定室内温度，且实际室内温度从未达到过(小于或等于)设定室内温度的情况，即为实际室内温度趋近设定室内温度且达到设定室内温度之前的情况。
S102、获得设定室内温度与第一实际室内温度的第一温度差值。
S103、获得第一温度差值的绝对值由第一温度阈值缩小至第二温度阈值所需的间隔时长。
其中，第二温度阈值小于温度死区阈值，第二温度阈值用于表示可将第一温度差值等价为零；例如，第二温度阈值可为0℃，或者第二温度阈值为大于零且小于温度死区阈值的最大值的任一值，例如，第二温度阈值可为1℃。
第一温度阈值通常大于或等于温度死区阈值，在现有的其他温度控制方法中，在温度差值小于或等于温度死区阈值的情况下，则停止执行温度调节过程。在本申请实施例中，第一温度阈值大于或等于温度死区阈值，则可使空调由其他常规控制方法顺利地切换至本控制方法，空调可实现持续运行。
在一些应用场景中，第一温度阈值可为1℃～3℃。例如，第一温度阈值可为1℃、2℃或3℃。
无论空调处于制冷过程还是制热过程，在空调的调节作用下，第一温度差值的绝对值不断缩小。可将第一温度差值的绝对值等于第一温度阈值的时刻，记为第一时刻；之后第一温度差值的绝对值持续缩小，将第一温度差值的绝对值等于第二温度阈值时刻，记为第二时刻，计算获得第一时刻和第二时刻之间的间隔时长，该间隔时长即为间隔时长。
S104、根据时长、压缩机频率与风机转速的对应关系，确定与间隔时长对应的第一压缩机频率和第一风机转速。
时长、压缩机频率与风机转速的对应关系，可预先存储在数据库中，在获得间隔时长之后，通过查询数据库，即可获得与间隔时长对应的第一压缩机频率以及第一风机转速。
可选地，根据时长、压缩机频率与风机转速的对应关系，确定与间隔时长对应的第一压缩机频率和第一风机转速，包括：在间隔时长小于第一时长阈值的情况下，将风机的最低转速确定为第一风机转速，将压缩机的最低频率确定为第一压缩机频率。
或者，根据时长、压缩机频率与风机转速的对应关系，确定与间隔时长对应的第一压缩机频率和第一风机转速，可包括：在间隔时长大于或等于第一时长阈值，且小于或等于第二时长阈值的情况下，在设定转速区间中确定第一风机转速，在设定频率区间中确定第一压缩机频率。
或者，根据时长、压缩机频率与风机转速的对应关系，确定与间隔时长对应的第一压缩机频率和第一风机转速，可包括：在间隔时长大于第二时长阈值的情况下，将原风机转速确定为第一风机转速，将原压缩机频率确定为第一压缩机频率；其中，原压缩机频率为第一温度差值的绝对值大于第二温度阈值且小于第一温度阈值时的压缩机频率，原风机转速为第一温度差值的绝对值大于第二阈值且小于第一温度阈值时的风机转速。
间隔时长越小，表示空调对房间温度的调节能力越强，包括以下三种情况：空调自身的制冷能力或制热能力较强，或者，房间空间的体积较小，或者，空调自身的制冷能力或制热能力较强且房间空间的体积较小；间隔时长越大，表示空调对房间温度的调节能力越弱，包括以下三种情况：空调自身的制冷能力或制热能力较弱，或者，房间空间的体积较大，或者，空调自身的制冷能力或制热能力较弱且房间空间的体积较小。
在上述技术方案中，可以是第一压缩机频率以及第一风机转速与空调对房间温度的调节能力相适配，根据第一压缩机频率以及第一风机转速控制空调，有利于房间温度稳定，实现了空调的不停机运行。
上述的设定转速区间的最小值可大于或等于风机的最低转速，设定转速区间的最大值可小于或等于风机转速的最高转速，或者，设定转速的最大值可小于或等于原风机转速；上述设定频率区间的最小值可大于或等于压缩机的最低频率，设定频率区间的最大值可小于或等于压缩机的最高频率，或者，设定频率区间的最大值可小于或等于原压缩机频率。
可将设定转速区中的任一值确定为第一风机转速，例如，可将设定转速区间的中间值确定为第一风机转速。同理，可将设定频率区间中的任一值确定为第一压缩机频率，例如，可将设定频率区间中的中间值确定为第一压缩机频率。
另外，还可通过其他方式在设定转速区间中确定第一风机转速，例如，获得第二时长阈值与第一时长阈值的时长阈值差值；在设定转速区间确定与时长阈值差值反相关，且与间隔时长正相关的第一风机转速。
具体地，可通过如下方式在设定转速区间中确定第一风机转速：
Figure PCTCN2022122775-appb-000001
其中，R 1为第一风机转速，R min为设定转速区间的最小值，R max为设定转速区间的最大值，ΔT为间隔时长，T 1为第一时长阈值，T 2为第二时长阈值。
通过上述方式确定的第一风机转速，可以与空调对房间温度的调节能力更加匹配。在空调持续运行的过程中，可使室内温度更加稳定。
可通过其他方式在设定频率区间中确定第一压缩机频率，例如：获得第二时长阈值与第一时长阈值的时长阈值差值；在设定频率区间中确定与时长阈值差值反相关，且与间隔时长正相关的第一压缩机频率。
具体地，可通过如下方式在设定频率区间中确定第一压缩机频率：
Figure PCTCN2022122775-appb-000002
其中，f 1为第一压缩机频率，f min为设定频率区间的最小值，f max为设定频率区间的最大值，ΔT为间隔时长，T 1为第一时长阈值，T 2为第二时长阈值。
通过上述方式确定的第一压缩机频率，可以与空调对房间温度的调节能力更加匹配。在空调持续运行的过程中，可使室内温度更加稳定。
在一些具体应用中，第一时长阈值可为5min～15min。例如，第一时长阈值可为5min、10min或15min。第二时长阈值可为50min～70min，例如，第二时长阈值可为50min、55min、60min、65min或70min。
以下对同时在设定转速区间中确定第一风机转速，在设定频率区间中确定第一压缩机频率，进行说明。
可选地，在设定转速区间中确定第一风机转速，在设定频率区间中确定第一压缩机频率，包括：将室内机的原盘管温度确定为设定盘管温度；其中，原盘管温度为第一温度差值等于第二温度阈值时的盘管温度；在设定转速区间中确定第一风机转速，根据实际盘管温度和设定盘管温度在设定频率区间中确定第一压缩机频率，使实际盘管温度维持在设定盘管温度。
这样，首先确定第一风机转速，再动态确定第一压缩机频率，动态确定的第一压缩机频率有利于将实际盘管温度维持在设定盘管温度，在空调的不停机运行过程中，有利于进一步维持室内温度的稳定。
进一步地，根据实际盘管温度和设定盘管温度在设定频率区间中确定第一压缩机频率，包括：在制热过程中，在实际盘管温度低于设定盘管温度的情况下，在设定频率区间中确定一频率较高的第一压缩机频率；在实际盘管温度高于设定盘管温度的情况下，在设定频率区间中确定一频率较低的第一压缩机频率。
根据实际盘管温度和设定盘管温度在设定频率区间中确定第一压缩机频率，还可包括：在制冷过程中，在实际盘管温度低于设定盘管温度的情况下，在设定频率区间中确定一频率较低的第一压缩机频率；在实际盘管温度高于设定盘管温度的情况下，在设定频率区间中确定一频率较高的第一压缩机频率。
这样可将实际盘管温度维持在设定盘管温度。
通过上述技术方案，即可获得使空调的制冷能力或制热能力与室内空间体积相匹配的 第一压缩机频率以及第一风机转速。
S105、根据第一压缩机频率和第一风机转速控制空调。
在本申请实施例中，根据第一压缩机频率和第一风机转速控制空调，指的是使压缩机的实际运行频率维持在第一压缩机频率，以及使室内风机的实际转速维持在第一风机转速。
在设定室内温度与第一实际室内温度的第一温度差值缩小至第一温度阈值的情况下，表示第一实际室内温度将要达到设定室内温度；在第一温度差值缩小至第二温度阈值的情况下，表示第一实际室内温度已达温；第一实际室内温度即将达温至达温所需的间隔时长可反映空调的自身制冷能力/制热能力与房间空间体积的对应关系，即，间隔时长可反映空调对房间温度的调节能力，利用间隔时长对应第一压缩机频率以及第一风机转速对空调进行控制，可以使空调的运行状态与空调对房间的调节能力相匹配，便于在空调不停机的情况下，仍使实际室内温度维持稳定，避免出现空调频繁启停的现象，提高实际室内温度的稳定性，提高用户的温度体验。
为了实现对室内温度的闭环控制，在根据第一压缩机频率和第一风机转速控制空调持续运行第一时长之后，空调的控制方法还包括：获得第二实际室内温度，以及设定室内温度与第二实际室内温度的第二温度差值；在第二实际室内温度超过设定室内温度，且第二温度差值的绝对值大于或等于第三温度阈值的情况下，根据第二压缩机频率控制空调，第二压缩机频率小于第一压缩机频率。
或者，在根据第一压缩机频率和第一风机转速控制空调持续运行第一时长之后，空调的控制方法还可包括：获得第二实际室内温度，以及设定室内温度与第二实际室内温度的第二温度差值；在第二实际室内温度超过设定室内温度，且第二温度差值的绝对值小于第三温度阈值的情况下，继续根据第一压缩机频率和第一风机转速控制空调。
或者，在根据第一压缩机频率和第一风机转速控制空调持续运行第一时长之后，空调的控制方法还可包括：在第二实际室内温度未超过设定室内温度的情况下，如果间隔时长小于第一时长阈值，则在设定转速区间中确定第二风机转速，在设定频率区间中确定第三压缩机频率，并根据第三压缩机频率和第二风机转速控制空调；如果间隔时长大于或等于第一时长阈值，且小于或等于第二时长阈值，将原风机转速确定为第二风机转速，将原压缩机频率确定为第三压缩机频率，并根据第三压缩机频率和第二风机转速控制空调。
上述第三温度阈值可为1℃～3℃。例如，第三温度阈值可为1℃、2℃或3℃。
这样，在空调不停机运行的过程中，实现了对室内温度的闭环控制，更有利于维持室内温度的稳定。

S205、根据第一压缩机频率和第一风机转速控制空调持续运行第一设定时长。
其中，第一设定时长与空调对房间的调温能力正相关。对于按照好的空调而言，空调的最大制冷功率或最大制热功率越大，则第一设定时长越大；空调所在房间的体积越大，则第一设定时长越小。
具体地，第一设定时长可以是3min～8min。例如，第一设定时长可为3min、4min、5min、6min、7min或8min。
S206、获得第二实际室内温度，以及设定室内温度与第二实际室内温度的第二温度差值。
S207、在第二实际室内温度超过设定室内温度，且第二温度差值的绝对值大于或等于第三温度阈值的情况下，根据第二压缩机频率控制空调，第二压缩机频率小于第一压缩机频率。
可选地，第二实际室内温度超过设定室内温度，包括：在空调处于制冷模式下，第二实际室内温度小于设定室内温度；在空调处于制热模式下，第二实际室内温度大于设定室内温度。
第二压缩机频率可为零，即，表示空调停机。
S208、在第二实际室内温度超过设定室内温度，且第二温度差值的绝对值小于第三温度阈值的情况下，继续根据第一压缩机频率和第一风机转速控制空调。
S209、在第二实际室内温度未超过设定室内温度的情况下，如果间隔时长小于第一时长阈值，则在设定转速区间中确定第二风机转速，在设定频率区间中确定第三压缩机频率，并根据第三压缩机频率和第二风机转速控制空调；如果间隔时长大于或等于第一时长阈值，且小于或等于第二时长阈值，将原风机转速确定为第二风机转速，将原压缩机频率确定为第三压缩机频率，并根据第三压缩机频率和第二风机转速控制空调。
其中，第二实际室内温度未超过设定室内温度，包括：在空调处于制冷模式下，第二实际室内温度大于或等于设定室内温度；在空调处于制热模式下，第二实际室内温度小于或等于设定室内温度。

第二设定时长大于第一设定时长，以减少对空调的反复调节，降低室内温度的变化速率，提高室内温度的稳定性。
具体地，第二设定时长可以是8min～13min。例如，第二设定时长可为8min、9min、10min、11min、12min或13min。
该步骤中的第二压缩机频率不为零。
S308、获得第三实际温度，以及设定室内温度与第三实际温度的第三温度差值。
