Description

空调室外机的除尘方法、装置及空调室外机

技术领域
本公开涉及空调设备技术领域，具体而言，涉及一种空调室外机的除尘方法、除尘装置及空调室外机。
背景技术
空调室外机长期暴露在外，换热器上容易沾染灰尘。积尘严重时，会影响换热效果，还会降低机组使用寿命。
为解决这一问题，已知的方法有两种。一种方法是清洁提醒，机组判断换热器积尘后提醒清洁，然后需要人工清理。这种方法费时费力。另一种方法是机组判断换热器积尘后自动除尘，通过风机反转除尘。这种方法需要精确判断换热器积尘情况，如果除尘过于频繁，则浪费能源，且除尘时空调无法工作，影响用户体验。如果除尘不够及时，则灰尘会越积越多，最后风机反转也无法除掉灰尘。
针对相关技术中如何精准确定机组除尘周期从而保证除尘效果的问题，目前尚未提出有效的解决方案。

图1是根据本公开实施例的机组除尘方法的流程图；
图2是根据本公开实施例的机组除尘装置的结构框图。
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明白，下面结合实施方式和附图，对本公开做进一步详细说明。在此，本公开的示意性实施方式及其说明用于解释本公开，但并不作为对本公开的限定。
下面结合附图详细说明本公开的可选实施例。
实施例1
图1是根据本公开实施例的空调室外机(以下简称机组)的除尘方法的流程图，如图1所示，该方法包括以下步骤：
步骤S101，确定机组的积尘系数；
步骤S102，根据积尘系数确定累计积尘值；
步骤S103，判断累计积尘值是否超过预设值，如果是，则触发除尘操作。
通过本实施例，能够实现空调室外机的自动除尘，免去人工清理环节。并且实现针对空调室外机除尘时机的精确判断，及时除尘，避免不必要的浪费，提高机组性能及使用寿命。
本实施例中涉及的积尘系数的大小，与工作模式和/或工作频率有关。也就是说，需要先确定机组的工作模式和/或工作频率，再根据工作模式和/或工作频率确定机组的积尘系数。上述工作模式分为待机模式和运行模式。待机模式下与运行模式下有不同的积尘系数，一般情况下，待机模式下的积尘系数小于运行模式下的积尘系数。积尘系数还与工作频率(风机频率)有关，一般情况下，风机频率越高，积尘系数越大。
在一些实施例中，积尘系数通过以下方式确定：在机组首次上电时，对机组进行定位；根据定位信息获取当地的空气质量参数；根据空气质量参数确定积尘系数。例如，对于不同的空气质量或者不同的季节，其对应的积尘系数也有所不同。可以根据 需求或经验设置空气质量参数与积尘系数的对应表，依此来确定与空气指令参数对应的积尘系数。
在一些实施例中，确认积尘系数的方式为：在机组首次上电时，对机组进行定位，根据定位信息获取当地的空气质量参数；以及，确定机组的工作模式和/或工作频率；结合空气质量参数，以及，工作模式和/或工作频率，确定机组的积尘系数。也就是说，在具体实现时，可以基于经验或需求，预先设置空气质量参数、工作模式和/或工作频率，与积尘系数的对应关系，根据该对应关系可以准确得到积尘系数。基于此，可以同时考虑当地空气状况以及机组当前工作状况，确定最合适的积尘系数。
当然，积尘系数的确定方式并不仅限于前面介绍的几种实施方式，还可以是机组出厂默认设置一个系数，后续随着机组的运行再进行调整。积尘系数的确定综合考虑各个影响因素(例如空气质量、工作模式和工作频率等)，在一些实施例中，积尘系数的确定考虑上述多个因素中的一个或多个。
表1是示例性说明风机频率与积尘系数的关系。将风机频率划分为多个区间，不同区间对应不同的积尘系数。当然，在上例中的数值只是为了解释实施方式，不代表真实值，具体各参数应根据不同机型的特性来制定，积尘系数的区间划分也不限于表1中的例子。
表1
风机频率f f＝0 0＜f≤30 30＜f≤60 60＜f
积尘系数 1 1.5 2 2.5
在确定积尘系数之后，在机组使用过程中，根据积尘系数确定累计积尘值，具体可以通过以下公式实现：累计积尘值Y＝∑积尘系数K×时间t。例如，预设值X为500，机组的积尘系数K参见表1，当机组待机300h，风机在40Hz下运行60h。此时累计积尘值Y＝1×300+2×60＝420，累计积尘值Y＜预设值X，则机组不进入除尘运行。后续机组继续运行，风机以30Hz运行到第54个小时时，累计积尘值Y＝1×300+2×60+1.5×54＝501＞预设值X。此时触发机组的除尘操作
对于上述预设值X的设置，在机组出厂时有一个默认预设值。机组首次上电调试时，对机组定位，根据定位信息设置预设值。具体地址，可以是通过大数据分析，根据定位信息采集当地其他机组的预设值，计算当地其他机组的预设值的平均值，将平均值确定为预设值。后续维护人员也可以根据实际除尘效果调节预设值。
当机组判断累计积尘值超出预设值，需除尘时，可以选择在下一次停机后执行风 机反转除尘，也可以立即停机，执行一次风机反转除尘操作。对于选择哪种除尘方式，可以根据用户需要进行选择，也可以根据累计除尘值与预设值的差值大小确定，如果二者差值较大(例如差值超过预设阈值)，则立即停机进行风机反转除尘，如果差值较小，则待机组正常停机后再风机反转除尘。基于此，能够立即实现机组的除尘，也可以等机组正常停机时再执行除尘操作。能够准确把控除尘时机，避免过度除尘浪费资源，也避免除尘不及时影响机组使用。

通过本实施例，能够实现空调室外机的自动除尘，免去人工清理环节。并且实现针对空调室外机除尘时机的精确判断，及时除尘，避免不必要的浪费，提高机组性能及使用寿命。
在一些实施例中，上述第一处理模块10，具体用于确定机组的工作模式和/或工作频率；根据工作模式和/或工作频率确定机组的积尘系数。上述第二处理模块20通过以下公式确定累计积尘值：累计积尘值Y＝∑积尘系数K×时间t。
