具体实施方式
为使本公开的目的、技术方案和优点更加清楚，下面将对本公开的技术方案进行 详细的描述。显然，所描述的实施例仅仅是本公开一部分实施例，而不是全部的实施例。基于本公开中的实施例，本领域普通技术人员在没有做出创造性劳动的前提下所得到的所有其它实施方式，都属于本公开所保护的范围。
发明人注意到，在一些应用场景中，如空调内机和空调外机的厂家或型号不同，空调内机和空调外机不能进行数据通信，空调外机不能获取到室内数据，只能依靠温控器提供的外机开关机电平信号实现开关机控制。这种情况下，空调外机由于不能获取室内数据只能按照固定的控制方式如固定功率运行，可能导致空调外机功率与室内需求不匹配的情况出现。若外机功率小于室内需求，则空调持续工作时间会较长，影响用户体验；若外机功率大于室内需求，则会出现空调外机频繁开停状况，影响空调能效。
图1为本公开一些实施例提供的房间面积获取方法的流程图，如图1所示，该房间面积获取方法，包括步骤S11-步骤S15。
在S11：根据空调型号参数设定房间面积初始值。
在一些实施例中，空调型号参数包括空调的制冷量。在设定房间面积初始值后，当前房间面积值为房间面积初始值。
在S12：获取空调外机开机稳定运行至温度点停机的稳定运行时长和停机次数。
在S13：根据稳定运行时长和停机次数估计房间面积初始值与房间面积实际值的偏差，输出偏差结果，偏差结果包括当前房间面积值偏大或当前房间面积值偏小。
应理解，估计房间面积初始值与房间面积实际值的偏差即估计当前房间面积值与房间面积实际值的偏差。
在S14：根据偏差结果调整房间面积初始值，根据调整后房间面积值重新进行估计。
应理解，如果S13输出的偏差结果为当前房间面积值偏大，则在步骤S14将房间面积初始值调小；如果S13输出的偏差结果为当前房间面积值偏小，则在步骤S14将房间面积初始值调大。
在调整房间面积初始值后，当前房间面积值为调整后的房间面积值。根据稳定运行时长和停机次数重新估计调整后的房间面积值与房间面积实际值的偏差，输出偏差结果。换言之，以调整后的房间面积值作为房间面积初始值重复执行步骤S13。
在S15：在本次估计输出的偏差结果与上一次估计输出的偏差结果不同时，将当前房间面积值作为房间面积实际值。
例如，本次估计输出的偏差结果为当前房间面积值偏大，上一次估计输出的偏差结果为当前房间面积值偏小。又例如，本次估计输出的偏差结果为当前房间面积值偏小，上一次估计输出的偏差结果为当前房间面积值偏大。在这些情况下，当前房间面积值是根据上一次输出的偏差结果对房间面积初始值进行调整后的房间面积值，
发明人知晓的房间面积获取方法是通过空调内机与空调外机进行通信，空调内机直接将室内面积信息发送至空调外机，以便于外机调整运行参数实现稳定运行。但发明人注意到，在一些应用场景中，如空调内机和空调外机的厂家或型号不同，空调内机和空调外机不能进行数据通信，空调外部不能获取到室内数据，只能依靠温控器提供的外机开关机电平信号实现开关机控制。这种情况下，空调外机由于不能获取室内数据只能按照固定的控制方式如固定功率运行，可能导致空调外机功率与室内需求不匹配的情况出现，因此需要在内外机无通讯情况下，使外机可以准确获取内机所在房间的面积。
上述实施例中，房间面积获取方法包括根据空调型号参数设定房间面积初始值，获取空调外机开机稳定运行至温度点停机的稳定运行时长和停机次数，根据稳定运行时长和停机次数估计房间面积初始值与房间面积实际值的偏差，输出偏差结果，偏差结果包括当前房间面积值偏大或当前房间面积值偏小；根据偏差结果调整所述房间面积初始值，根据调整后房间面积值重新进行估计；在本次估计输出偏差结果与上一次估计输出偏差结果不同时，将当前房间面积值作为房间面积实际值。这样的方式下，可以在内外机无法通讯的情况下准确获取房间面积，之后根据房间面积调整外机运行参数，从而解决外机功率与室内需求不匹配的问题，提高用户体验，提高外机运行稳定性。
图2为本公开另一些实施例提供的房间面积获取方法的流程图。如图2所示，在一些实施例中，该房间面积获取方法包括步骤S201、S202、S203、S207和S208。在另一些实施例中，该房间面积获取方法包括步骤S201、S202、S203、S204、S207和S208。在又一些实施例中，该房间面积获取方法包括步骤S201、S202、S205、S207和S208。在还一些实施例中，该房间面积获取方法包括步骤S201、S202、S205、S206、S207和S208。在还一些实施例中，该房间面积获取方法包括步骤S201、S202、S203、S204、S205、S206、S207和S208。
在S201：根据空调的制冷量设定房间面积初始值。
例如，若空调制冷量为1.5匹，设定房间面积初始值为20平方米。
在S202：获取空调外机开机稳定运行至温度点停机的稳定运行时长和停机次数。
在一些实施例中，获取空调外机开机稳定运行至温度点停机的稳定运行时长，包括：
S2021：获取外机开机至稳定运行时的第一时间点；
S2022：获取外机稳定运行后至接收到停机信号时的第二时间点；
S2023：将第二时间点与所述第一时间点的时间差作为空调外机开机稳定运行至到达温度点停机的稳定运行时长。
在一些实施例中，房间面积获取方法还包括：
若预设时间内接收到停机信号的次数超过预设次数阈值，则判定开关控制异常。
在一些应用场景中，温控器出现异常或认为频繁控制开关机。若使用本公开的方法进行房间面积估计每一轮输出偏差结果都是房间面积偏大，需要持续减小房间面积，最终会导致输出房间面积实际值过小，由于外机功率调整与房间面积实际值对应，在外机再次开机时，会造成室内制冷/制热效果不佳，影响用户体验。
本公开一些实施例中，通过判断是否出现开关控制异常可以有效避免上述情况出现。例如，若检测到在5min内超过3次收到开、关机信号，则判断为开关控制异常，此时，初始化房间面积为房间面积初始值，确保外机开机后不会因为开关控制异常造成估计的房间实际面积太小，导致开机功率过低。
在S203：若稳定运行时长大于预设稳定运行时长阈值，则输出偏差结果为当前房间面积值偏小。
本公开一些实施例中，预设稳定运行时长阈值为1小时。
在S204：按照预设第一步进值增加房间面积。
本公开一些实施例中，第一步进值为1平方米。
一些实施例中，若增加房间面积达到预设房间面积值上限值后，输出偏差结果为当前房间面积值偏小，将房间面积值上限值作为房间面积实际值。
因受到上限值限制，上限值对应外机最大功率，房间面积无法增加到实际房间大小，说明外机即使满功率运行也无法满足室内需求，这种情况下，控制外机保持最大功率运行。
在S205：若稳定运行时长小于预设稳定运行时长阈值，且，停机次数不小于预设次数，且，本次稳定运行时长与上一次稳定运行时长的差值小于预设时长差值，则输出偏差结果为当前房间面积值偏大。
本公开一些实施例中，预设稳定运行时长阈值为1小时，预设次数为3次，预设时长差值为3分钟。
在S206：按照预设第二步进值减小房间面积。
本公开一些实施例中，第二步进值为1平方米。
一些实施例中，若减小房间面积达到预设房间面积值下限值后，输出偏差结果为当前房间面积值偏大，将房间面积值下限值作为房间面积实际值。
因受到下限值限制，下限值对应外机最低功率，房间面积无法减小到实际房间面积大小，说明外机选型功率过大，性能过剩，为保持机组稳定可靠，保持外机最低功率运行。
在S207：根据调整后房间面积值重新进行估计。
在S208：在本次估计输出偏差结果与上一次估计输出偏差结果不同时，将当前房间面积值作为房间面积实际值。
通过多轮调整后，房间面积值达到实际房间大小，此时外机功率与室内需求相匹配。
在一些实施例中，房间面积获取方法还包括步骤S209-步骤S211。
在S209：判断房间面积实际值与房间面积初始值的差值是否大于预设差值，若是，执行S210，否则，执行S211。
在S210：检测到用户关机时，根据空调型号参数设定房间面积初始值。
在S211：检测到用户关机时，将房间面积实际值设定为房间面积初始值。
在一些实施例中，检测用户关机方法包括但不限于以下方式：
方式1，停机超过预设时间(例如1h)没有收到开机信号。因为在制冷模式下超过1h不开机，房间肯定会热起来，温控器肯定会发出控制开机指令，因此，若超过1h没有收到开机信号，认为是人为关机，制热同理。
方式2，接收到温控器发出关机信号。
在一些实施例中，检测用户关机方法包括方式1和方式2中的一种或多种。
考虑到外机运行要能够实现室内的快速制冷或制热问题，如果遇到长时间没有开机，季节、气候等因素会影响室内功率需求的变化，因此若本次估计出的房间面积实际值比房间面积初始值小预设值(例如3平方米)，则在检测到用户关机时，重新设定初始值为房间面积初始值，以确保不会出现因为开机功率过低影响用户体验的情况。
一些实施例中，如图3所示，获取房间面积的具体过程包括如下步骤。
步骤1，机组上电，根据机型预设房间面积S 房。
步骤2，进行数据初始化，例如，到温度点停机次数＝0，本次稳定运行时长T 稳＝0，上一次稳定运行时长T 上一次稳＝0，上一次估计房间大小偏差结果＝0；进入待机状态，持续检测是否有开机信号。
步骤3，外机收到开机信号后，机组开机，直到稳定运行一段时间(例如5min)，T 稳开始计时。
步骤4，持续检测是否有关机信号，当外机稳定运行1小时(T 稳>1h)没有收到关机信号,则判断S 房偏小，并记录估计房间大小状态为偏小，然后S 房增加1m 2，T稳重新计时。
步骤5，如果上一次估计房间状态偏大，则判断完成对房间大小的估计，保持当前S’ 房状态运行直至收到关机信号，执行步骤8；否则重新执行步骤4。
步骤6，如果外机稳定运行时间不足1小时(T 稳<1h)收到关机信号，到温度点停机次数+1，然后判断到温度点停机次数是否大于3次，且稳定运行时间是否和上一次稳定运行时间接近(|T 稳-T 上一次稳|≤3min)。如果符合则判断S 房偏大，并记录估计房间大小状态为偏大，然后S 房减少1m 2。
步骤7，记录本次稳定运行时间后关机，然后进入停机时长判断。如果停机不超过1h接收到开机信号，则确定是到温度点停机，保存数据，然后执行步骤2。
步骤8，判断S’ 房是否比根据机型预设房间面积S 房小3m 2，如果是，执行步骤1；否则，执行步骤2。
如果停机超过1h，则判断用户关机。
本公开一些实施例可以实现无通讯外机在有温控器持续提供开机信号的情况下，经过长时间稳定运行后，压缩机频率出现提升，并一直保持稳定运行。通过多轮估计，无通讯外机在一定时间内接收到多次停机信号后，再次开机直到压缩机频率稳定，压缩机稳定运行频率降低。并且，当压缩机频率经过算法调节后，短时间内频繁收到温控器开关机信号，判断为开关控制异常，压缩机频率恢复为初始面积对应值。
本公开一些实施例中，在空调内外机没有直接数据交互的情况下，能够自动调节外机运行参数以适应室内需求，优化室内温度调节效果，提高用户体验，避免了因内外机缺少数据交互，造成室内温度调节超调或欠调的问题，同时也能够实现更好的节能效果。并且，能够减少外机正常运行过程的停机次数，让空调外机运行更稳定，延长空调使用寿命。
图4为本公开一些实施例提供的空调外机控制方法的流程图，如图4所示，该空调外机控制方法，包括步骤S41和步骤S42。
在S41：根据上述实施例所述的房间面积获取方法得到房间面积实际值。
在S42：根据房间面积实际值控制空调外机的空调运行参数。
本公开一些实施例中，空调运行参数包括但不限于压缩机的频率和外风机转速等。
一些实施例中，根据房间面积实际值控制空调外机的空调运行参数可以通过预设房间面积与空调运行参数对照表，通过查表方式获取空调运行参数以控制空调外机稳定运行。
需要说明的是，本公开对空调外机的控制方法并不限定，本公开所提供的空调外机控制方法适用于其他根据房间面积对空调外机进行控制的应用场景中。
发明人知晓的房间面积获取方法是通过空调内机与空调外机进行通信，空调内机直接将室内面积信息发送至空调外机，以便于外机调整运行参数实现稳定运行。但在一些应用场景中，如空调内机和空调外机的厂家或型号不同，空调内机和空调外机不能进行数据通信，空调外部不能获取到室内数据，只能依靠温控器提供的外机开关机电平信号实现开关机控制。这种情况下，空调外机由于不能获取室内数据只能按照固定的控制方式如固定功率运行，可能导致空调外机功率与室内需求不匹配的情况出现。
