Description

用于控制空调升温灭菌的方法及装置、空调
本申请基于申请号为202010759123.9、申请日为2020年07月31日的中国专利申请提出，并要求该中国专利申请的优先权，该中国专利申请的全部内容在此引入本申请作为参考。
技术领域
本申请涉及智能家电技术领域，例如涉及一种用于控制空调升温灭菌的方法及装置、空调。
背景技术
目前，家居环境的洁净和健康性已被越来越多的用户所重视，空调作为一种常见调节室内环境温湿度的空气设备，其洁净程度的高低能够极大的影响到室内环境的洁净性。从空调长期的使用经验来看，在空调长时间运行后，室内换热器表面可能存在病菌、细菌、霉菌等微生物，常规自清洁无法有效灭菌，导致病菌通过空调在房间内循环，不利于人体健康。针对这一情况，现有空调厂家也研发制造了很多具备高温清洁功能的空调产品，通过升高室内换热器的温度，实现高温杀菌、清洁。
在实现本公开实施例的过程中，发现相关技术中至少存在如下问题：
在室内换热器升温灭菌的过程中，内盘管温度波动较大，导致换热器不能稳定的维持在目标温度上，使得灭菌效果差。
发明内容
为了对披露的实施例的一些方面有基本的理解，下面给出了简单的概括。所述概括不是泛泛评述，也不是要确定关键/重要组成元素或描绘这些实施例的保护范围，而是作为后面的详细说明的序言。
本公开实施例提供了一种用于控制空调升温灭菌的方法及装置、空调，以解决室内换热器升温灭菌时，内盘管温度波动较大导致换热器温度不能稳定在目标温度上，灭菌效果差的技术问题。
在一些实施例中，所述方法包括：将目标换热器的温度升至目标温度以上进行灭菌；根据室内盘管温度设置节流装置的开度，使所述室内盘管温度与所述目标温度的差值小于阈值。

通过在空调自清洁执行升温过程时，根据室内盘管温度设置节流装置的开度，以调节管路内流动的制冷剂，使得室内盘管温度靠近换热器的目标温度。如此，在升温灭菌过程中，细菌通过空气循环附着在室内盘管和换热器的翅片上，由于室内盘管温度在节流装置的调节下能够稳定在目标温度附近，使得换热器温度快速稳定达到目标温度后，也能够稳定在目标温度上，避免了温度波动导致灭菌效果不理想情况的发生，使得空调能够在目标温度上高效稳定的进行灭菌清洁。

具体实施方式
为了能够更加详尽地了解本公开实施例的特点与技术内容，下面结合附图对本公开实施例的实现进行详细阐述，所附附图仅供参考说明之用，并非用来限定本公开实施例。在以下的技术描述中，为方便解释起见，通过多个细节以提供对所披露实施例的充分理解。然而，在没有这些细节的情况下，一个或多个实施例仍然可以实施。在其它情况下，为简化附图，熟知的结构和装置可以简化展示。
本公开实施例的说明书和权利要求书及上述附图中的术语“第一”、“第二”等是用于区别类似的对象，而不必用于描述特定的顺序或先后次序。应该理解这样使用的数据在适当情况下可以互换，以便这里描述的本公开实施例的实施例。此外，术语“包括”和“具有”以及他们的任何变形，意图在于覆盖不排他的包含。
除非另有说明，术语“多个”表示两个或两个以上。
本公开实施例中，字符“/”表示前后对象是一种“或”的关系。例如，A/B表示：A或B。
术语“和/或”是一种描述对象的关联关系，表示可以存在三种关系。例如，A和/或B，表示：A或B，或，A和B这三种关系。
结合图1所示，本公开实施例提供一种用于控制空调升温灭菌的方法，包括：
步骤S01，将目标换热器的温度升至目标温度以上进行灭菌。
在执行步骤S01的升温过程时，在目标换热器为室内换热器时，空调调整系统内冷媒流向与制热模式的冷媒流向一致，使得输入目标换热器(即室内换热器)的冷媒为高温冷媒，以利用高温冷媒加热目标换热器，实现高温灭菌的清洁作用。
这里，在一些可选的实施例中，空调的遥控器和控制面板上新增有“灭菌功能”或“灭菌功能”等的清洁选项，该清洁选项可用于触发运行本实施例中空调升温灭菌的清洁流程。这样在用户对该清洁选项进行选定操作后，空调生成相关的清洁指令，并响应执行，使得目标换热器的温度升至目标温度以上。
在又一些可选的实施例中，空调也可以通过检测触发、定时触发等方式生成相关的清洁指令，例如，空调增设有微生物检测装置，可用于检测一种或多种特定类型微生物的含量，则在检测到的微生物的含量高于设定的含量阈值时，说明空调滋生的微生物较多，空调生成相关的清洁指令；又或者，空调具有计时模块，可用于统计空调累计运行的时长如制冷模式或者除湿模式的累计运行时长，这里随着空调制冷模式或者除湿模式的累计运行时长的增加，空调内部冷凝的冷凝水也就越多并且在该种湿润环境中微生物繁殖增长的数目也就越多，因此可以设定在空调累计运行时长超过设定时长阈值时，空调生成相关的清洁指令，使得目标换热器温度升至目标温度以上进行灭菌清洁。
在又一些可选的实施例中，空调也可以与空调原有清洁功能进行联动触发，如在用户选定原有清洁功能后，在执行该原有清洁功能限定的清洁流程之前生成清洁指令并执行本申请的清洁方法流程，或者在执行该原有清洁功能限定的清洁流程之后生成清洁指令并执行本申请的清洁方法流程；也即用户在选定一原有清洁功能之后，空调是先后执行了两种不同的清洁流程，通过双重清洁的方式有效保障了空调内部的洁净度。
例如，空调原有清洁功能为喷淋清洗功能，该喷淋清洗功能是将水喷淋至空调的换热器上，以通过流水冲刷的方式清洁换热器，则一种可选的实施方式是本申请的升温灭菌方法流程是在执行喷淋清洗功能之前运行，也即在用户选定喷淋清洗功能之后，先控制执行本申请升温灭菌方法流程杀灭细菌等微生物，之后在执行喷淋清洗功能，这样流水不仅可以冲洗掉灰尘、油污等污垢，同时也可以将换热器上被杀灭的微生物一并冲刷掉。
又例如，空调原有清洁功能为凝霜-化霜的清洁模式，包括先将空调系统内冷媒流向调整为与制冷模式的冷媒流向一致，使输入室内换热器的冷媒为低温冷媒，以利用低温冷媒的吸热蒸发作用降低室内换热器的温度，使得室内空气流经室内换热器时，水蒸气就在室内换热器上进行凝结，水汽从气态-液态-固态的转变过程中能够剥离室内换热器表面的灰尘、油污等污垢，不仅可以提高对体积较大的污染物的清洁效果，同时也能够使污垢深层的微生物裸露出来，从而更易被杀灭。在满足化霜条件后，将空调系统内冷媒流向调整为与制热模式的冷媒流向一致，此时输入室内换热器的冷媒为高温冷媒，以利用高温冷媒加热室内换热器，室内换热器表面上凝结的冰霜在吸收热量后融化，从而实现“化霜”。达到化霜温度后，室内换热器继续升温至目标温度以上，从而在化霜基础上进一步的实现 “灭菌”的清洁。
步骤S02，根据室内盘管温度设置节流装置的开度，使室内盘管温度与目标温度的差值小于阈值。
这里，阈值用于表示一个较小的数值，在室内盘管温度与目标温度的差值小于该阈值时，认为室内盘管温度接近目标温度，以实现将室内盘管温度稳定在目标温度附近的目的。可选地，阈值的取值范围为[0.5,2]，可以是0.5、1、1.5或2。
在持续升温过程中，以及达到目标温度后的设定时长内，根据室内盘管温度设置节流装置的开度，使得室内盘管温度靠近目标温度，避免室内盘管温度波动导致换热器温度不稳定，不能很好的完成灭菌清洁。
采用本公开实施例提供的用于控制空调升温灭菌的方法，通过在空调自清洁执行升温过程时，根据室内盘管温度设置节流装置的开度，以调节管道内流通的制冷剂，使得室内盘管温度靠近换热器的目标温度。如此，在升温灭菌过程中，细菌通过空气循环附着在室内盘管和换热器的翅片上，由于室内盘管温度在节流装置的调节下能够稳定在目标温度附近，使得换热器温度快速稳定达到目标温度后，也能够稳定在目标温度上，因此空调能够在目标温度上高效稳定的进行灭菌清洁。
可选地，目标温度满足如下条件：
T 0+T 阈值＜T pmax          (1)
其中，T 0为目标温度，T 阈值为调节数值，其取值范围为2℃～3.5℃，T pmax为室内盘管的最高温度。如此，根据室内盘管的最高温度确定换热器的目标温度，使得目标温度在满足灭菌要求的同时，不影响空调系统的整机压力条件。可选地，室内盘管的最高温度T pmax是根据制冷剂种类确定的。
例如是，对于其内流通R32制冷剂的空调制冷系统来说，室内盘管的最高温度为63℃，则目标温度与调节数值之和小于63℃。具体地，调节数值T 阈值设置为3℃，则目标温度T 0的取值范围为小于60℃。考虑到杀菌清洁的要求，将目标温度设定为56摄氏度以上。如此，在该目标温度下，一方面能够实现空调的高温杀菌功能，在高温环境下清洁清除换热器翅片上滋生或附着的细菌，清除室内空气中附着的病毒、细菌；另一方面，能够满足系统压力条件，使得制冷系统稳定运行。
可选地，室内盘管温度越高，节流装置的开度越大。这里，室内盘管温度是指升温过程中和/或达到目标温度后的预设时长内，室内盘管的温度。通过根据室内盘管温度设置节流装置的开度，使得室内盘管温度稳定在目标温度上。室内盘管温度较高时，增大节流装置的开度，以增加制冷剂的流动速度，加快降温，使室内盘管温度稳定在目标温度上。
例如是，当室内盘管温度与目标温度相近时，设置节流装置开度为第一阈值的较小开度，此时制冷剂流量较低，使得室内盘管温度缓慢上升，不断趋近到设定温度；当室内盘管温度相对于目标温度较高时，设置节流装置开度为第二阈值的开度，这里第二阈值对应的开度高于第一阈值。此时，通过增加节流装置的开度提高管路内制冷剂流量，实现降温， 使得室内盘管温度逐渐降低至设定温度；当室内盘管温度接近室内盘管的最高温度时，设置节流装置开度为较高的第三阈值的开度，这里第三阈值对应的开度高于第二阈值。此时，通过增大节流装置的开度，增加管路内制冷剂流量、流速，实现快速降温，使得室内盘管温度可以维持在目标温度上。
示例性的，表1中示出一种可选的室内盘管温度T p与节流装置开度F s的对应关系。
表1
室内盘管温度T p(℃) 节流装置开度F s
T p<T 0+1 F 1
T 0+1≤T p≤T 0+3 F 1+x
T p>T 0+3 F 1+y
其中，F 1表示一对应于相应室内盘管温度的节流装置预设开度，x、y分别表示不同的开度增量，其中x表示的开度增量小于y表示的开度增量。
如表1所示，在本实施例中，对室内盘管温度预设3个温度区间，其对应的节流装置开度的数值依次增大。表1中示出了室内盘管温度所在的不同温度区间所对应的节流装置开度的取值，在本实施例中，升温灭菌的自清洁过程中节流装置开度的取值可以通过查表的方式确定。
可选地，节流装置的开度根据如下方式确定：
F s＝a×T p+k           (2)
其中，F s为节流装置的开度，T p为室内盘管温度，k为修正参数，a为大于0的加权值。
如此，根据算式(2)可通过室内盘管温度设定空调的节流装置开度。室内盘管温度越高，节流装置开度就越高。需要注意的是，在算式(2)的计算时，进行F s、T p数值的代数式求值，不进行单位换算。
这里，空调预设有室内盘管温度与加权值a的关联关系，该关联关系包括室内盘管温度与加权值a的一一对应关系，通过查找该关联关系就能够获取与当前室内盘管温度所对应的加权值a的取值，得到一与当前室内盘管温度对应的修正前的节流装置开度值。可选地，加权值a的取值还与空调接收清洁指令前的工作模式有关。根据不同的工作模式，为加权值a设置不同的数值。
可选地，修正参数k根据室内盘管温度与目标温度的差值以及室外环境温度确定的。如此，在根据室内盘管温度设置节流装置的开度时，通过室内盘管温度与目标温度的差值以及室外环境温度共同对节流装置的开度进行修正，使得对节流装置开度的调整更加精准，能够通过节流装置开度的调节，进一步将室内盘管温度稳定在目标温度上，使得空调整机运行平稳，高温灭菌效果好。
可选地，根据室内盘管温度与目标温度的差值及室外环境温度确定修正系数，包括：确定室内盘管温度与目标温度的差值所在的温度区间；根据预设的对应关系，确定温度区 间和室外环境温度所对应的修正系数。
这里，空调预设有室内盘管温度与目标温度的差值、室外环境温度与修正系数的关联关系，该关联关系包括室内盘管温度与目标温度的差值所在的温度区间、室外环境温度与修正系数取值的对应关系。因此通过查找该关联关系就能够获取与当前室内盘管温度与目标温度的差值和室外环境温度所对应的修正系数，进而控制节流装置根据该修正系数调节开度后改变管路内制冷剂的流量。
可选地，在室外环境温度相同的情况下，室内盘管温度与目标温度的差值所在的温度区间越高，修正系数k的取值越大。
如此，对于同一室外环境温度下的不同室内机，根据其室内盘管温度与目标温度差值所在的温度区间调节修正系数k的取值，以修正节流装置的开度，使其能够对室内盘管温度产生影响，不断趋近目标温度。
可选地，在室内盘管温度与目标温度的差值相同的情况下，室外环境温度越高，修正系数k的取值越大。如此，在室内盘管温度、空调目标温度相同的情况下，根据室外环境温度调节修正系数k的取值，以修正节流装置的开度，使其能够对室内盘管温度产生影响，不断趋近目标温度。
可选地，实时的或按照预定时间间隔获取室内盘管温度。例如是，在对换热器的升温过程中，实时的获取室内盘管温度以设置节流装置的开度。也可以是，在对换热器的升温过程中，按照预定时间间隔获取室内盘管温度以设置节流装置的开度。这里，预定时间间隔可以是1min，2min，4min或5min。
采用本公开实施例提供的用于控制空调升温灭菌的方法，通过在空调自清洁执行升温过程时，根据室内盘管温度调节节流装置的开度，以调整管路内流通的制冷剂，使得室内盘管温度靠近换热器的目标温度。如此，在升温灭菌过程中，细菌通过空气循环附着在室内盘管和换热器的翅片上，由于室内盘管温度在节流装置的调节下能够稳定在目标温度附近，使得换热器温度快速稳定达到目标温度后，也能够稳定在目标温度上，因此空调能够在目标温度上高效稳定的进行灭菌清洁。
结合图2所示，本公开实施例提供的另一种用于控制空调升温灭菌的方法，包括：
步骤S11，将目标换热器的温度升至目标温度以上进行灭菌。
步骤S12，根据室内盘管温度设置节流装置的开度，使室内盘管温度与目标温度的差值小于阈值。
步骤S13，在室内盘管温度与所述目标温度的差值大于或等于阈值的情况下，根据室内盘管温度和室外环境温度设置室内风机的转速。
在调节节流装置开度后，无法使得室内盘管温度与目标温度的差值小于阈值的情况下，通过调节室内风机转速，实现驱使室内盘管温度不断趋近目标温度，使得换热器温度快速稳定达到目标温度后，也能够稳定在目标温度上，因此空调能够在目标温度上高效稳定的进行灭菌清洁
可选地，根据室内盘管温度、室外环境温度共同设置室内风机的转速，使室内盘管温度与目标温度的差值小于阈值。这里的阈值与前述实施例中的阈值意义相同，用于表述一个较小的数值，在室内盘管温度与目标温度的差值小于该阈值时，认为室内盘管温度接近目标温度，以实现将室内盘管温度稳定在目标温度附近的目的。
可选地，室内盘管温度越高，室内风机的转速越高。这里，室内盘管温度是指升温过程中和/或达到目标温度后的预设时长内，室内盘管的温度。通过根据室内盘管温度调节室内风机转速，使得室内盘管温度稳定在目标温度上。室内盘管温度较高时，提高室内风机转速以加快送风实现室内盘管温度的快速降温，使其维持在目标温度上。
例如是，当室内盘管温度与目标温度相近时，设置室内风机以较低转速转动，缓慢吹风，使得室内盘管温度不断趋近到目标温度；当室内盘管温度相对于目标温度较高时，设置室内风机以较高转速转送，加快送风，使得室内盘管温度逐渐降低至目标温度；当室内盘管温度接近室内盘管的最高温度时，设置室内风机高速转动，实现快速降温，使得室内盘管温度可以维持在目标温度上。
如表2所示，空调内预设有室内盘管温度、室外环境温度与室内风机转速之间的对应关系。

根据室内盘管温度与室外环境温度共同设置室内风机的转速，其中室内盘管温度与室内风机的转速成正相关关系；室外环境温度与室内风机的转速成正相关关系。表3的横表头为从小到大依次设置的多个室外环境温度数值，column(n)为室外环境温度数值与对应室内风机转速所在的列；纵表头为从小到大依次设置的多个室内盘管温度数值，line(l)为室内盘管温度数值与对应室内风机转速所在的行；column(n)与line(l)所交集处为室外环境温度与室内盘管温度所对应的室内风机转速。可以根据研发阶段对典型工况的实验数据，对根据室内盘管温度确定的室内风机转速、根据室外环境温度确定的室内风机转速进行拟合后获得上述的对应关系。这里，室内风机转速可以是具体的转数，也可以是转速所在的档位。
可选地，在获取室内盘管温度、室外环境温度后，通过查表的方式在表3中取最接近实际温度的数值所在行、列对应的室内风机转速，实现根据室内盘管温度、室外环境温度 共同设置室内风机的转速，能够通过室内风机转速的调节，使室内盘管温度不断趋近目标温度，达到杀菌清洁的要求。
具体地，表3示出了一种可选的室内环境温度、室外环境温度与室内风机转速之间的对应关系。

其中，R1表示室内风机转速的范围为(430,470)，x、y、z分别为转速增量，其中，x表示的转速增量小于y表示的转速增量。这里，需要注意的是，增加转速增量后的风机转速仍然小于或等于相同条件下预设的空调静音最大转速。当增加转速增量后的风机转速高于该条件下的空调静音最大转速时，以空调静音最大转速运转。
采用本公开实施例提供的用于控制空调升温灭菌的方法，通过在空调自清洁执行升温过程时，根据室内盘管温度调节节流装置的开度，以调整管路内流通的制冷剂，使得室内盘管温度靠近换热器的目标温度，并在室内盘管温度无法趋近换热器目标温度的情况下，根据室内盘管温度与室外环境温度共同调节室内风机转速，以使得室内盘管温度稳定在目标温度上。室内盘管温度较高时，提高室内风机转速以加快送风实现室内盘管温度的快速降温，使其维持在目标温度上。如此，在升温灭菌过程中，细菌通过空气循环附着在室内盘管和换热器的翅片上，由于室内盘管温度在节流装置的调节下能够稳定在目标温度附近，使得换热器温度快速稳定达到目标温度后，也能够稳定在目标温度上，因此空调能够在目标温度上高效稳定的进行灭菌清洁。
结合图3所示，本公开实施例提供另一种用于控制空调升温灭菌的方法，包括：
步骤S21，响应于清洁指令，对目标换热器进行凝霜。
通过控制空调，使目标换热器凝霜。在本实施例中以室内换热器作为目标换热器。对目标换热器的凝霜操作包括关闭四通阀，控制室内机导板向上，控制压缩机运行频率、节流装置开度固定，使得室内换热器凝霜。
步骤S22，满足化霜条件后，将目标换热器的温度升至目标温度以上进行化霜和灭菌。
可选地，目标温度为一高于化霜温度的数值，目标温度的取值范围为55℃至65℃。可以是55℃、60℃或65℃。在执行步骤S12的升温过程时，空调调整系统内冷媒流向与制热模式的冷媒流向一致，此时输入室内换热器的冷媒为高温冷媒，以利用高温冷媒加热室内换热器，室内换热器表面上凝结的冰霜在吸收热量后融化，从而实现“化霜”。这里，化霜温度可以根据霜层厚度、环境温度、环境湿度中的一个或多个共同确定。达到化霜温度后，室内换热器继续升温至设定温度以上，从而在化霜基础上进一步的实现“灭菌”。
步骤S23，根据室内盘管温度、室外环境温度共同设置节流装置的开度，使室内盘管温度与目标温度的差值小于阈值。
空调内预设有室内盘管温度、室外环境温度与节流装置开度之间的对应关系。根据室内盘管温度与室外环境温度共同设置节流装置的开度，其中室内盘管温度的高低与节流装置开度的大小正相关关系；室外环境温度与节流装置开度的大小成正相关关系。可以根据研发阶段对典型工况的实验数据，对根据室内盘管温度确定的节流装置开度、根据室外环境温度确定的节流装置开度进行拟合后获得上述的对应关系。这里，节流装置开度可以是具体的开度数值，也可以是开度所在的档位。
可选地，在获取室内盘管温度、室外环境温度后，通过查表的方式在预存的对应关系中取最接近实际温度的数值所在行、列对应的节流装置开度，实现根据室内盘管温度、室外环境温度共同设置节流装置开度，能够通过节流装置开度的调节，调整管路内流通的制冷剂，使室内盘管温度不断趋近目标温度，达到杀菌清洁的要求。
具体地，表4示出了一种可选的室内环境温度、室外环境温度与节流装置开度之间的对应关系。

T p3 T p>T s+3 F1+n F1+k+n F1+2k+n
其中，F1表示室外环境温度低于17℃，室内盘管温度与目标温度的差值小于1的情况下对应的节流装置开度，m、n、k分别为开度增量，其中，n表示的开度增量大于m表示的开度增量。
步骤S24，满足灭菌完成条件后，退出清洁模式，控制空调恢复到清洁前的工作模式。
其中，灭菌完成条件包括以下条件中的一个或多个：室内换热器的盘管温度在第一预设时长中，数值持续大于第一设定温度；室内换热器的盘管温度变化量，在第一预设时长中，数值持续小于第一设定变化量；压缩机的连续运行时间大于第二预设时长；换热器达到目标温度的时长满足第二预设时长。其中，第一预设时长设定为5-7分钟，第二预设时长设定为30-35分钟。这样，通过统计升温过程中设定时间内温度变化情况或压缩机的工作情况，在满足灭菌完成条件后，退出清洁模式。
采用本公开实施例提供的用于控制空调升温灭菌的方法，通过在空调自清洁的凝霜-化霜程序后，继续执行升温过程，并根据室内盘管温度调节室节流装置开度，使得室内盘管温度靠近换热器的目标温度。如此，在升温灭菌过程中，细菌通过空气循环附着在室内盘管和换热器的翅片上，由于室内盘管温度在室内风机的调节下能够稳定在目标温度附近，使得换热器温度快速稳定达到目标温度后，也能够稳定在目标温度上，因此空调能够 在目标温度上高效稳定的进行灭菌清洁。
如图4所示，本公开实施例提供的一种用于控制空调升温灭菌的方法，包括：
步骤S31，将目标换热器的温度升至目标温度以上进行灭菌。
步骤S32，根据室内盘管温度设置室内风机的转速，使室内盘管温度与目标温度的差值小于阈值。
步骤S33，在满足灭菌完成条件的情况下，判断是否满足除霜条件，当满足除霜条件时，执行对室外换热器进行除霜，否则退出升温灭菌的清洁模式，控制空调恢复到灭菌清洁前的工作模式。
可选地，除霜条件是根据室外环境温度与室外换热器盘管温度确定的。其中，室外换热器盘管温度可以通过室外换热器上的除霜传感器采集。通过采集室外环境温度可以计算室外空气的凝露点温度。比较该凝露点温度与室外换热器盘管温度的大小，当室外换热器盘管温度在设定时间内持续小于或等于该凝露点温度时，满足该除霜条件，对室外换热器进行除霜。
可选地，凝露点温度是通过如下方式获得的：
T es＝C×T ao-e           (3)
其中，T es为凝露点温度，T ao为室外环境温度，C为根据室外环境温度确定的加权值，e为常数。
可选地，当室外环境温度小于0℃时，加权值C的数值设定为0.8；当室外环境温度大于或等于0℃时，加权值C的数值设定为0.6。常数e的取值范围为4-7，可以是4、5、6或7。
可选地，对于室外换热器的除霜，可通过设置在室外换热器上的除霜电路实现对室外换热器的加热除霜；也可通过冷媒流向进行切换，使得空调切换到以室外换热器作为冷凝器工作的状态，对室外换热器进行除霜，使得冷媒在流经室外换热器时冷凝放热，提高室外换热器的温度，以化除室外换热器上附着的冰霜，并在室外换热器上附着的冰霜化除后，保持以室外换热器作为冷凝器的工作状态继续运行，使室外换热器的温度继续升高至退出除霜模式。
可选地，还可以通过在室外换热器上设置除霜传感器，已通过除霜传感器对室外换热器表面霜层情况或室外换热器的盘管温度的感应实现除霜模式的进入、退出。例如，除霜条件包括，除霜传感器检测室外换热器的外盘管温度小于第三设定温度。此时进入除霜模式，开启室外换热器上设置的除霜电路进行加热除霜。当除霜传感器检测到室外换热器的外盘管温度大于或等于第四设定温度时，退出除霜模式。可选地，同时退出升温灭菌的清洁模式，控制空调恢复到凝霜前的工作模式。
采用本公开实施例提供的用于控制空调升温灭菌的方法，通过在凝霜过程后执行升温流程，并在升温流程后，在空调满足除霜条件的情况下，执行除霜流程。通过除霜流程，一方面对室外换热器在室内换热器快速的升温过程中产生的霜层进行了清理，另一方面实 现了室外换热器的清洁。其中，在升温过程中根据室内盘管温度调节节流装置开度，使得室内盘管温度靠近换热器的目标温度。如此，在升温灭菌过程中，细菌通过空气循环附着在室内盘管和换热器的翅片上，由于室内盘管温度在节流装置的调节下能够稳定在目标温度附近，使得换热器温度快速稳定达到目标温度后，也能够稳定在目标温度上，因此空调能够在目标温度上高效稳定的进行灭菌清洁。

此外，上述的存储器101中的逻辑指令可以通过软件功能单元的形式实现并作为独立的产品销售或使用时，可以存储在一个计算机可读取存储介质中。
存储器101作为一种计算机可读存储介质，可用于存储软件程序、计算机可执行程序，如本公开实施例中的方法对应的程序指令/模块。处理器100通过运行存储在存储器101中的程序指令/模块，从而执行功能应用以及数据处理，即实现上述实施例中用于控制空调升温灭菌的方法。
存储器101可包括存储程序区和存储数据区，其中，存储程序区可存储操作系统、至少一个功能所需的应用程序；存储数据区可存储根据终端设备的使用所创建的数据等。此外，存储器101可以包括高速随机存取存储器，还可以包括非易失性存储器。
