空调化霜控制方法及空调控制器
相关申请
本申请要求2018年06月13日申请的，申请号为201810608423.X，名称为“空调化霜控制方法及空调控制器”的中国专利申请的优先权，在此将其全文引入作为参考。
技术领域
本申请涉及设备控制技术领域，特别是涉及一种基于自学习的空调化霜控制方法及空调控制器。
背景技术
传统空气源热泵在冬季制热运行时，空气侧换热器处于低压侧，湿度大时运行一段时间后会结霜，需要进行化霜以保证空调正常运行。现有的化霜方法主要有定时化霜和分环境温度区间的半智能化霜方法。
在实现本申请过程中，发明人发现现有的化霜方法至少具有以下缺陷：
采用定时化霜的方式来控制空调进入化霜状态时，有时进入化霜的时间并不合适，可能还未结霜就进行化霜，也可能霜已经积攒很多了还没进入化霜状态，从而会严重影响空调的使用效果，而且定时化霜不节能。
半智能化霜则需要在开发时投入大量的人力与时间进行试验验证，而且涉及化霜的一些参数在机器出厂时是属于厂家级参数，实际工况变化时机器不能智能调节，需要厂家开发人员手动控制，由于实验室内不能验证所有的工况，因此，售后机组会出现程序验证不完全导致的低压保护等故障。

本申请提出的一种基于自学习的空调化霜控制方法及空调控制器，能够解决传统空调化霜不智能问题，有效提升机组运行的智能化，同时保证机组安全、高效运行。图1示意性示出了本申请一个实施例的空调化霜控制方法的方法流程图。参照图1，本申请实施例的空调化霜控制方法具体包括以下步骤：
步骤S101、按照预设的时间间隔采集机组在当前制热周期内空气侧换热器的低压温度和各个温度采集时刻对应的制热运行时间。
步骤S102、根据获取的所述低压温度和所述制热运行时间计算各个温度采集时刻对应的低压温度变化率和低压降低幅度值。
步骤S103、当所述低压温度变化率或所述低压降低幅度值满足对应的化霜条件时，控制机组进入化霜操作。
其中，低压温度变化率对应的第一预设化霜条件为低压温度变化率小于或等于预设的变化率阈值；低压降低幅度值对应的第二预设化霜条件为低压降低幅度值小于或等于预设的温度阈值。具体的，通过可判断低压温度变化率和所述低压降低幅度值是否满足对应的化霜条件，决定机组进入化霜的时间，当所述低压温度变化率小于或等于预设的变化率阈值，或所述低压降低幅度值小于或等于预设的温度阈值时，则控制机组进入化霜操作。
在本申请实施例中，空调控制器按照预设的时间间隔采集空调机组运行过程中t0、t1、t2...等时刻的低压温度T0、T1、T2。其中t0是低压温度采集启示时间，t0为压缩机频率升高到机组在该工况下允许的最高频率的时刻，通过计算机组低压温度变化率和低压降低幅度，根据比较φ的变化规律和低压降低幅度ΔT0做出机组是否满足化霜的判断，并进行化霜动作，并且每次化霜时都进行智能计算，最终使空调在当前环境条件下选择在最适宜的时机进入化霜。
具体的，低压温度变化率φ和低压降低幅度值ΔT0的计算公式如下：
ΔT0＝(T2-T0)∈[-14，-4]℃且T2≥-30℃，φ＝(T2-T1)/(t2-t1)，其中，低压变化率φ在运行期间的不同时间呈现出一定的规律性，φ一般先是逐渐减小，减到最小后，逐步升高，变化范围为φ∈[-1.4，-0.2]℃/min。预设的时间间隔可为预设的固定值，也可以根据应用环境进行设定。本实施例中时间间隔的取值为1min，即每1min采集并计算1次。
例如，φ在一个制热周期内的变化和ΔT0进行比较，判定哪个先满足对应的预设化霜条件，如果φ在一个制热周期内的检测时间段内先达到预设的变化率阈值，即-1.4℃/min，而ΔT0尚未达到规定的化霜进入条件，则机组根据低压温度变化率φ，确定机组进入化霜操作的时机。
本实施例中，空调控制器主要负责采集空调机组在当前制热期间的工作参数，如空气 侧换热器的低压温度和各个温度采集时刻对应的制热运行时间、环境温度等。其中，低压压力值的变化如图2，随制热时间的变化，低压由于结霜的原因逐渐降低，尤其在湿度很大的情况下，低压的变化趋势如图2。
本申请实施例提供的空调化霜控制方法，使得空调器动态的、灵活的根据采集的运行参数和运行参数的变化率及变化幅度自动判断机组结霜情况，自主决定机组进入化霜的时间，以控制机组进入化霜操作，使得空调能够适应更加复杂的工况而无需人工干预，有效提升机组运行的智能化，同时保证机组安全、高效运行。本申请和传统化霜方法相比能避免延迟化霜带来的运行安全问题，以及提前化霜导致的热量损失。
在一个实施方式中，本申请提供的空调化霜控制方法还包括：根据当前制热周期内各个温度采集时刻对应的低压温度变化率和低压降低幅度值确定下一个制热周期的制热时间长度。
本申请为了还能够通过当前制热周期化霜的时间，修正下一个制热周期机组进入化霜的时间。具体实现如下：获取当前制热周期内的第一制热运行时间和第二制热运行时间，所述第一制热运行时间根据所述低压温度变化率满足对应的化霜条件时对应的制热运行时间进行确定，所述第二制热运行时间根据所述低压降低幅度值满足对应的化霜条件时对应的制热运行时间进行确定。选取所述第一制热运行时间与所述第二制热运行时间中时间长度较小的值作为下一个制热周期的制热时间长度，以根据下一个制热周期的制热时间长度，控制下一个制热周期机组进入化霜操作的时间。
其中，第一制热运行时间为当前制热周期内所述低压温度变化率满足对应的化霜条件时对应的制热运行时间，或当前制热周期内所述低压温度变化率满足对应的化霜条件时对应的制热运行时间延长预设时间长度后的制热运行时间。在实际应用中，可以通过将低压温度变化率达到预设的变化率阈值时对应的制热运行时间延长预设时间长度，以保证临界值覆盖，进而在提升机组运行的智能化的同时，保证机组安全、高效运行。其中，在一个具体示例中，预设时间长度可选为1-5分钟。具体的，预设时间长度的具体取值可预先设置，也可根据外部环境的温度和湿度情况进行调整，本申请不对其进行具体限定。
其中，第二制热运行时间为当前制热周期内所述低压降低幅度值满足对应的化霜条件时对应的制热运行时间。
本申请实施例提供的空调化霜控制方法，通过根据低压温度变化率φ在一个制热周期内的变化和低压降低幅度值ΔT0，选取低压温度变化率和低压降低幅度值中先满足对应的预设化霜条件的制热运行时间确定后一个制热周期的制热时间长度，进而控制后一个制热周期机组进入化霜操作的时间，使得空调能够适应更加复杂的工况而无需人工干预，有效 提升机组运行的智能化，同时保证机组安全、高效运行。
在一个实施方式中，在所述判断所述低压温度变化率和所述低压降低幅度值是否满足对应的化霜条件之前，所述方法还包括：获取外部环境温度；根据所述外部环境温度确定所述温度阈值。
按照环境温度对低压降低幅度值的温度阈值进行设定，具体划分标准如下：
T环≥-5℃，ΔT0＝-14℃；
-14-℃≤T环＜-5℃，ΔT0＝-14℃+(-5℃-T环)；
T环≤-15℃，ΔT0＝-4℃。
在实际应用中，可以按照环境温度对低压降低幅度值的温度阈值进行设定，确保温度阈值取值的准备，进而在提升机组运行的智能化的同时，保证机组安全、高效运行。
在一个实施方式中，当按照所述预设的变化率阈值或预设的温度阈值进行化霜操作控制过程中机组出现过低压保护时，则分别对所述预设的变化率阈值和预设的温度阈值进行修正，以在下一个制热周期时根据修正后的变化率阈值和温度阈值进行第一制热运行时间和第二制热运行时间的确定。
如果机组在结霜很厚的情况下没有化霜就断电或关机，要求机组记忆上一个周期的运行参数并在首次开机时依照上次运行的控制进行化霜。如果依照上述规则运行时机组出现过低压保护，则运算修正模块修正当前φ和ΔT0，具体为：φ在当前存储值得基础上升高指定单位，例如：0.2℃，ΔT0在当前存储值的基础上升高指定单位，例如：2℃，并且机组再次启动运行时，开机马上进行化霜，故障清除之后按修正后的修正程序1运行。
在一个可选方案中，还可以在机组增加湿度传感器，可以按照湿度进行智能化霜，湿度大时制热间隔时间缩短，湿度小时，制热间隔时间增长，使得机组化霜更智能。
本申请实施例提出的基于自学习的空调化霜控制方法，解决了传统空调化霜不智能的问题，由于拥有自学习功能，可以使空调动态的、灵活的根据采集的参数和运行过程参数的变化率及变化幅度自动判断机组结霜情况，自主决定机组进入化霜的时间，使机组化霜更智能，可以适应任何工况而健康、安全的运行。和传统化霜方法相比能避免延迟化霜带来的运行安全问题或提前化霜导致的热量损失。
本本申请实施例以化霜为例说明，但该方法的应用不限于化霜，可以扩展至其他方面如：根据用户的生活习惯进行运行等。
对于方法实施例，为了简单描述，故将其都表述为一系列的动作组合，但是本领域技术人员应该知悉，本申请实施例并不受所描述的动作顺序的限制，因为依据本申请实施例，某些步骤可以采用其他顺序或者同时进行。其次，本领域技术人员也应该知悉，说明书中 所描述的实施例均属于优选实施例，所涉及的动作并不一定是本申请实施例所必须的。
