技术领域Technical field

本申请涉及空调技术领域，尤其涉及空调器的控制方法、空调器和计算机可读存储介质。The present application relates to the technical field of air conditioning, and in particular to a control method of an air conditioner, an air conditioner and a computer-readable storage medium.

背景技术Background technique

随着经济技术的发展，空调器的应用越来越广泛，空调器的性能也越来越多样化。其中，大多数空调器具有自清洁功能，通过先制冷结霜凝结换热器上的脏物，再制热或制冷融霜将脏物带走，以清洁换热器。目前，大多空调器制冷结霜一般通过空调制冷运行时对换热器相应的风机运行进行调控，使换热器盘管温度足够低在换热器表面结霜。With the development of economy and technology, the application of air conditioners is becoming more and more widespread, and the performance of air conditioners is becoming more and more diversified. Among them, most air conditioners have a self-cleaning function. They first cool and condense the dirt on the heat exchanger, and then heat or cool and defrost to take away the dirt to clean the heat exchanger. At present, most air conditioner refrigeration frosts are generally controlled by regulating the operation of the corresponding fan of the heat exchanger during the refrigeration operation of the air conditioner, so that the temperature of the heat exchanger coil is low enough to form frost on the surface of the heat exchanger.

然而，目前空调器在自清洁模式的制冷结霜阶段内风机控制参数一般是单一且固定的，风机控制参数在空调器出厂前保存在存储器中，然而当存储参数出现错误或空调器出厂后更换室内机时，容易造成风机控制参数与空调器的实际运行特性不匹配，导致空调器的制冷结霜阶段无法正常结霜，影响空调器的自清洁效果。并且，空调器在自清洁的结霜阶段的时长一般为预先设置的固定时长，而空调器的应用场景多样化，这容易造成自清洁结霜状态与空调器的实际工况不匹配，换热器上所结的霜层容易过厚或过薄，导致空调器的自清洁效果不佳。However, the current fan control parameters of air conditioners during the refrigeration and frosting phase of self-cleaning mode are generally single and fixed. The fan control parameters are stored in the memory before the air conditioner leaves the factory. However, when the stored parameters are incorrect or the air conditioner is replaced after leaving the factory, When using an indoor unit, it is easy to cause a mismatch between the fan control parameters and the actual operating characteristics of the air conditioner, causing the air conditioner to be unable to frost normally during the cooling and frosting phase, affecting the self-cleaning effect of the air conditioner. Moreover, the duration of the self-cleaning frosting phase of the air conditioner is generally a preset fixed duration, and the application scenarios of air conditioners are diverse, which can easily lead to a mismatch between the self-cleaning frosting state and the actual operating conditions of the air conditioner, resulting in poor heat exchange. The frost layer on the air conditioner is easily too thick or too thin, resulting in poor self-cleaning effect of the air conditioner.

The frost layer can meet the cleaning requirements and effectively improve the self-cleaning effect of the air conditioner.

此外，制冷结霜阶段的运行时长不是预先设置的固定值，也是根据空调器所在环境的室内环境温度确定的，基于此，可保证目标换热器的结霜状态与室内环境的实际温度情况相匹配，有效避免目标换热器上所结霜层过厚或过薄，实现空调器自清洁效果的有效提高。In addition, the running time of the refrigeration frosting phase is not a preset fixed value, but is also determined based on the indoor ambient temperature of the environment where the air conditioner is located.

Matching can effectively prevent the frost layer on the target heat exchanger from being too thick or too thin, and effectively improve the self-cleaning effect of the air conditioner.

步骤S10，在空调器的自清洁模式下，获取所述空调器的室内机所属的目标类型；Step S10, in the self-cleaning mode of the air conditioner, obtain the target type to which the indoor unit of the air conditioner belongs;

自清洁模式具体为空调器以清洗室内换热器为目标运行的空调模式。自清洁模式可在接收到用户输入的自清洁模式的启动指令时开启，也可在空调器监测到其运行达到设定条件时开启。The self-cleaning mode is specifically an air conditioning mode in which the air conditioner operates with the goal of cleaning the indoor heat exchanger.

The target type is one of at least two preset types.

具体的，可根据室内机中的电机类型将室内机划分成第一类型和第二类型；或，根据室内机是否允许制冷与制热切换将室内机划分成第三类型和第四类型。其中，所述第一类型的室内机中的电机为直流电机，所述第二类型的室内机中的电机为交流电机，所述第三类型的室内机为单冷机，第四类型的室内机为冷暖机。Specifically, the indoor unit can be divided into the first type and the second type according to the motor type in the indoor unit; or the indoor unit can be divided into the third type and the fourth type according to whether the indoor unit allows switching between cooling and heating. Wherein, the motor in the first type of indoor unit is a DC motor, the motor in the second type of indoor unit is an AC motor, the third type of indoor unit is a single cooler, and the fourth type of indoor unit The machine is a heating and cooling machine.

在本实施例中，目标类型包括第一类型、第二类型和第三类型中的一种。基于此，可在第一类型、第二类型以及第三类型中确定其中之一为所述空调器的室内机所属的目标类型。在其他实施例中，目标类型也可包括第三类型和第四类型中的一种，基于此，可在第三类型和第四类型中确定室内机所属的目标类型。In this embodiment, the target type includes one of a first type, a second type, and a third type. Based on this, one of the first type, the second type, and the third type may be determined to be the target type to which the indoor unit of the air conditioner belongs. In other embodiments, the target type may also include one of the third type and the fourth type. Based on this, the target type to which the indoor unit belongs can be determined in the third type and the fourth type.

步骤S20，根据所述目标类型确定风机控制参数；Step S20, determine the fan control parameters according to the target type;

具体的，可预先设置有用于室内换热器结霜的室内风机运行的多种预设参数，多种预设参数保存在空调器的存储器中，读取存储器中的多种预设参数，在多种预设参数中确定其中之一为风机控制参数。Specifically, a variety of preset parameters for indoor fan operation for indoor heat exchanger frosting can be preset. The multiple preset parameters are stored in the memory of the air conditioner, and the multiple preset parameters in the memory are read. One of the multiple preset parameters is determined to be the fan control parameter.

风机控制参数可包括室内风机的转速控制参数和/或开闭控制参数等。在本实施例中，所述风机控制参数包括风机参数集合中之一，所述风机参数集合包括：The fan control parameters may include rotation speed control parameters and/or opening and closing control parameters of the indoor fan.

Alternatively, different target types can correspond to the same fan control parameters. The fan control parameters corresponding to the target type are the operating parameters of the indoor fan that can make the frost layer on the surface of the indoor heat exchanger in the indoor unit of the target type reach the preset condition. The preset condition is specifically that the frost layer on the indoor heat exchanger reaches the preset thickness range within the target time. In this embodiment, the preset thickness range has a maximum value and a minimum value. In other embodiments, the preset thickness range is specifically a range greater than or equal to the set thickness. The corresponding relationship between the target type and the fan control parameters can be set in advance, and the fan control parameters corresponding to the target type can be determined based on the corresponding relationship.

步骤S30，控制所述空调器制冷运行且根据所述风机控制参数控制所述空调器的室内风机运行，以使所述空调器的室内换热器结霜；Step S30, control the cooling operation of the air conditioner and control the indoor fan operation of the air conditioner according to the fan control parameters, so as to frost the indoor heat exchanger of the air conditioner;

空调器制冷运行时室内换热器处于蒸发状态吸热、室外换热器处于冷凝状态放热。When the air conditioner is running for cooling, the indoor heat exchanger is in the evaporation state to absorb heat, and the outdoor heat exchanger is in the condensation state to release heat.

控制空调器制冷运行并根据风机控制参数控制室内风机运行达到目标时长后可执行步骤S40。这里的目标时长可为预先设置的固定时长，也可为根据空调器的实际运行情况所确定的时长。在目标时长内处于蒸发状态的目标换热器表面结霜，所结的霜层将目标换热器表面的脏物凝结。Step S40 can be executed after controlling the cooling operation of the air conditioner and controlling the operation of the indoor fan according to the fan control parameters to reach the target duration. The target duration here can be a preset fixed duration, or a duration determined based on the actual operating conditions of the air conditioner. Frost forms on the surface of the target heat exchanger that is in the evaporation state within the target duration, and the resulting frost layer condenses the dirt on the surface of the target heat exchanger.

具体的，开始计时获得计时时长并根据风机控制参数控制室内风机运行，在计时时长小于或等于目标时长时维持根据风机控制参数控制目标风机运行，在计时时长大于目标时长时执行步骤S40。Specifically, the timing is started to obtain the timing duration and the operation of the indoor fan is controlled according to the fan control parameters. When the timing duration is less than or equal to the target duration, the target fan operation is controlled according to the fan control parameters. When the timing duration is greater than the target duration, step S40 is executed.

风机控制参数为风机持续开启时，控制目标风机持续开启并维持目标时长后执行步骤S40；风机控制参数为风机持续关闭时，控制目标风机持续关闭且维持目标时长后执行步骤S40。When the fan control parameter is that the fan continues to be turned on, step S40 is executed after controlling the target fan to continue to be turned on and maintained for the target duration; when the fan control parameter is that the fan is continuously turned off, step S40 is performed after controlling the target fan to be continuously turned off and maintained for the target duration.

当风机控制参数为风机交替开启和关闭时，控制室内风机开启一段时长后关闭一段时长，若计时时长小于或等于目标时长则返回执行控制室内风机开启一段时长后关闭一段时长的步骤，若计时时长大于目标时长则执行步骤S40。或者，当风机控制参数为风机交替开启和关闭时，控制室内风机关闭一段时长后开启一段时长，若计时时长小于或等于目标时长则返回执行控制室内风机关闭一段时长后开启一段时长的步骤，若计时时长大于目标时长则执行步骤S40。When the fan control parameter is to alternately turn on and off the fan, control the indoor fan to turn on for a period of time and then turn off for a period of time. If the timing duration is less than or equal to the target duration, return to the step of controlling the indoor fan to turn on for a period of time and then turn off for a period of time. If the timing duration is If it is greater than the target duration, step S40 is executed. Or, when the fan control parameter is that the fan is turned on and off alternately, the indoor fan is controlled to be turned off for a period of time and then turned on for a period of time. If the timing duration is less than or equal to the target duration, return to the step of controlling the indoor fan to be turned off for a period of time and then turned on for a period of time. If If the timing duration is greater than the target duration, step S40 is executed.

当风机控制参数为风机先开启后关闭时，可控制室内风机先开启第一时长再关闭第二时长后执行步骤S40。When the fan control parameter is that the fan is turned on first and then turned off, the indoor fan can be controlled to be turned on for a first time and then turned off for a second time before step S40 is performed.

当风机控制参数为风机先关闭后开启时，可控制室内风机先关闭第二时长再开启第一时长后执行步骤S40。When the fan control parameter is that the fan is turned off first and then turned on, the indoor fan can be controlled to be turned off for a second period of time and then turned on for a first period of time before step S40 is performed.

步骤S40，控制所述空调器制热运行或制冷运行，以使所述目标换热器融霜。Step S40: Control the heating operation or cooling operation of the air conditioner to defrost the target heat exchanger.

控制空调器制冷运行并根据风机控制参数控制室内风机运行达到目标时长(即自清洁模式的结霜阶段)时，空调器进入自清洁模式的融霜阶段。When the cooling operation of the air conditioner is controlled and the indoor fan operation is controlled according to the fan control parameters to reach the target duration (i.e., the frosting phase of the self-cleaning mode), the air conditioner enters the defrosting phase of the self-cleaning mode.

在融霜阶段内，空调器的室内机为冷暖机时，空调器制热运行，室内换热器从蒸发状态切换至冷凝状态放热，空调器制热运行过程中室内换热器可依次经过融霜和干燥过程。其中，在融霜过程中所释放的热量使室内换热器表面的霜层融化，融霜水将霜层中所凝结的脏物带走，以实现对室内换热器的清洁。在空调器制热融霜过程中压缩机以允许运行的最大频率运行并维持第一预设时长(例如10分钟或15分钟等)。During the defrost phase, when the indoor unit of the air conditioner is a heating and cooling unit, the air conditioner operates for heating, and the indoor heat exchanger switches from the evaporation state to the condensation state to release heat. During the heating operation of the air conditioner, the indoor heat exchanger can pass through the Defrost and drying process. Among them, the heat released during the defrost process melts the frost layer on the surface of the indoor heat exchanger, and the defrost water takes away the condensed dirt in the frost layer to clean the indoor heat exchanger. During the heating and defrosting process of the air conditioner, the compressor operates at the maximum allowed operating frequency and maintains the first preset time period (such as 10 minutes or 15 minutes, etc.).

在融霜阶段内，空调器的室内机为单冷机时，空调器维持制冷运行，目标换热器维持蒸发状态，融霜阶段的室内换热器的盘管温度大于结霜阶段的室内换热器的盘管温度，室内换热器表面的冰霜从流经室内换热器的冷媒中吸收热量融化，融霜水将霜层中所凝结的脏物带走，以实现对目标换热器的清洁。在空调器制冷融霜过程中压缩机以低于制冷结霜阶段的频率运行。空调器的制冷融霜运行过程可维持第二预设时长(例如20分钟或25分钟等)，其中第二预设时长大于上述的第一预设时长。During the defrost phase, when the indoor unit of the air conditioner is a single cooler, the air conditioner maintains cooling operation and the target heat exchanger maintains the evaporation state. The coil temperature of the indoor heat exchanger in the defrost phase is greater than that of the indoor heat exchanger in the frost phase. The coil temperature of the heater, the frost on the surface of the indoor heat exchanger absorbs heat from the refrigerant flowing through the indoor heat exchanger and melts, and the defrost water takes away the condensed dirt in the frost layer to achieve the target heat exchanger. of cleanliness.

In the self-cleaning mode of the air conditioner, this method determines the fan control parameters of the air conditioner in the self-cleaning refrigeration and frosting stage according to the target type to which the indoor unit belongs. It avoids the mismatch between the fan control parameters and the operating characteristics of the air conditioner caused by the pre-storage error of a single fixed fan control parameter or the replacement of the indoor unit, effectively improves the matching degree between the control effect of the indoor fan and the operating characteristics of the indoor unit, and ensures the self-cleaning of the air conditioner.

In this embodiment, the preset thickness range has a maximum value and a minimum value. In other embodiments, the preset thickness range is specifically a range greater than or equal to the set thickness.

在空调器进入自清洁模式后，可实时检测室内环境温度；也可在空调器运行达到结霜条件时获取室内环境温度。After the air conditioner enters the self-cleaning mode, the indoor ambient temperature can be detected in real time; the indoor ambient temperature can also be obtained when the air conditioner reaches frosting conditions.

In other embodiments, the indoor ambient temperature can also be detected through other temperature detection modules located outside the indoor unit in the indoor environment. Among them, the indoor ambient temperature is the current real-time temperature of the environment where the air conditioner is located.

不同的室内环境温度对应不同的目标时长。在本实施例中，目标时长与室内环境温度呈正相关。也就是说，室内环境温度越高则目标时长越长，室内环境温度越低则目标时长越短。在其他实施例中，在室内环境温度大于预设温度时目标时长与室内环境温度呈正相关，在室内环境温度小于或等于预设温度时目标时长为固定值或室内环境温度与目标时长呈负相关。Different indoor ambient temperatures correspond to different target durations. In this embodiment, the target duration is positively correlated with the indoor ambient temperature. In other words, the higher the indoor ambient temperature, the longer the target duration, and the lower the indoor ambient temperature, the shorter the target duration. In other embodiments, when the indoor ambient temperature is greater than the preset temperature, the target duration is positively correlated with the indoor ambient temperature. When the indoor ambient temperature is less than or equal to the preset temperature, the target duration is a fixed value or the indoor ambient temperature is negatively correlated with the target duration. .

室内环境温度与目标时长之间的对应关系可预先设置，对应关系可具有映射关系、计算公式等形式。基于此，可通过室内环境温度代入预设公式计算得到目标时长；也可通过室内环境温度查询预设映射关系将匹配得到的结果作为目标时长。The corresponding relationship between the indoor ambient temperature and the target duration can be set in advance, and the corresponding relationship can be in the form of mapping relationship, calculation formula, etc. Based on this, the target duration can be calculated by substituting the indoor ambient temperature into the preset formula; the preset mapping relationship can also be queried through the indoor ambient temperature and the matching result can be used as the target duration.

在本实施例中，在空调器清洁模式下，制冷结霜阶段的运行时长不是预先设置的固定值，也是根据空调器所在环境的室内环境温度确定的，基于此，可保证目标换热器的结霜状态与室内环境的实际温度情况相匹配，有效避免目标换热器上所结霜层过厚或过薄，实现空调器自清洁效果的有效提高。In this embodiment, in the air conditioner cleaning mode, the running time of the refrigeration and frosting phase is not a preset fixed value, but is also determined based on the indoor ambient temperature of the environment where the air conditioner is located. Based on this, the operation time of the target heat exchanger can be guaranteed. The frosting state matches the actual temperature of the indoor environment, effectively preventing the frost layer on the target heat exchanger from being too thick or too thin, and effectively improving the self-cleaning effect of the air conditioner.

进一步的，在本实施例中，进一步的，在本实施例中，根据所述室内环境温度确定所述空调器结霜运行的目标时长的步骤包括：确定所述室内环境温度所在的温度区间；确定所述温度区间对应的预设运行时长为所述目标时长；其中，所述目标时长与所述温度区间内的温度呈正相关。Further, in this embodiment, further, in this embodiment, the step of determining the target duration of frosting operation of the air conditioner according to the indoor ambient temperature includes: determining the temperature interval in which the indoor ambient temperature is located; The preset running time corresponding to the temperature interval is determined to be the target time length; wherein the target time length is positively correlated with the temperature in the temperature interval.

其中，可预先将划分有至少两个预设温度区间，每个预设温度区间对应设置一个预设运行时长，预设运行时长与预设温度区间内的温度呈正相关。所划分的预设温度区间的数量可根据实际情况进行设置。Among them, at least two preset temperature intervals can be divided in advance, and each preset temperature interval is corresponding to a preset operating time, and the preset operating time is positively correlated with the temperature in the preset temperature interval. The number of divided preset temperature intervals can be set according to the actual situation.

具体的，可在至少两个预设温度区间中确定当前室内环境温度所在的温度区间，将该温度区间所对应关联的预设运行时长确定为目标时长。Specifically, the temperature interval in which the current indoor ambient temperature is located can be determined among at least two preset temperature intervals, and the preset running time corresponding to the temperature interval is determined as the target time length.

在本实施例中，预设温度区间的数量为三个，按照其区间内温度的大小从大到小排列依次为第一温度区间、第二温度区间以及第三温度区间，例如，在本实施例中，将大于或等于20℃的温度集合划分为第一温度区间，将小于20℃且大于或等于10℃的温度集合划分为第二温度区间，将小于20℃的温度集合划分为第三温度区间。需要说明的是，在其他实施例中，温度区间的临界值还可根据实际需求设置为其他数值。每个温度区间对应的预设运行时长依次为第一预设时长、第二预设时长以及第三预设时长，则当室内环境温度位于第一温度区间内时确定第一预设时长为目标时长，当室内环境温度位于第二温度区间内时确定第二预设时长为目标时长，当室内环境温度位于第三温度区间内时确定第三预设时长为目标时长。In this embodiment, the number of preset temperature intervals is three, and the temperatures in the intervals are arranged from large to small as the first temperature interval, the second temperature interval and the third temperature interval. For example, in this embodiment In this example, the temperature set greater than or equal to 20°C is divided into the first temperature interval, the temperature set less than 20°C and greater than or equal to 10°C is divided into the second temperature interval, and the temperature set less than 20°C is divided into the third temperature interval. temperature range. It should be noted that in other embodiments, the critical value of the temperature range can also be set to other values according to actual needs. The preset operating time corresponding to each temperature interval is the first preset time, the second preset and the third preset time. When the indoor ambient temperature is within the first temperature interval, the first preset time is determined as the target. Duration, when the indoor ambient temperature is within the second temperature range, the second preset duration is determined as the target duration, and when the indoor ambient temperature is within the third temperature range, the third preset duration is determined as the target duration.
