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。
相关技术中,对于结构较为庞大的空调机组设备或者多级联的空调系统,例如大型的中央空调机组等,往往会在室外布置多个不同容量的室外机,这些室外机组合在一起构成一个室外机组。空调机组运行时,每次从上述室外机组中选择一个或多个室外机来配合室内机协同运行。相关技术的方案在控制室外机组运行时没有考虑到室内机和室外机的具体运行情况,而是按照预先设定好的控制方案,机械地控制某几个室外机的运行。例如,第一个运行周期,按顺序控制1号室外机、3号室外机、4号室外机运行;在第二个运行周期,按顺序控制2号室外机、3号室外机、1号室外机运行。相关技术的方案没有考虑到实际场景中室内机和室外机的具体运行情况,导致不能充分地发挥各个室外机的性能,使得室外机组的运行能效较低、运行成本较高。同时,由于是按照预先设定好的控制方案,机械地控制室外机的运行,没有考虑到被控制运行的室外机的当前运行健康状态,例如,可能某几个室外机当前已经出现了一些运行不稳定的特征,出现了运行异常,但基于相关技术方案仍然会机械地控制上述室外机继续运行,导致室外机组的整体运行存在一定安全风险,也会对室外机的使用寿命造成影响,降低了整个机组运行的安全性和可靠性。可见,相关技术方案在具体实施时,往往存在室外机组运行能效低、稳定性差的技术问题。
针对产生上述问题的根本原因,本公开根据当前运行的室内机的容量数据、室外机和室内机的历史运行数据,来准确地确定出能针对性匹配且具有较高效能的室外机组合,从而提高了室外机的运行效能。此外,本公开基于室外机的健康度来确定各个室外机组合的优先级,再按照室外机组合的优先级轮换运行室外机组合,提高了室外机组整体运行的稳定性,从而解决了相关技术方案存在的室外机组运行能效低、稳定 性差的技术问题,达到高效、节能、稳定地运行室外机组的技术效果。
基于上述思考思路,本公开实施方式提供了一种室外机运行控制方法,参阅图1所示的根据本公开一些实施例的室外机运行控制方法的流程示意图,该方法具体包括以下步骤。
步骤S11:获取当前运行的室内机的容量数据。
在一些实施方式中,在运行诸如空调机组设备或者多级联空调系统时,需要同时运行室内机和室外机,使之相互配合、协同工作。例如,用户在开启室内的空调机(即一种室内机)降温时,还需要同时运行布置于室外的空调外机(即一种室外机),室内机和室外机相互配合才能达到降温的效果。
在一些实施方式中,需要说明的是,布置于室外的空调外机可以是一种包括多个并联的室外机的室外机组。该室外机组所包含的多个室外机可以分别独立运行,不受其他室外机的影响;且不同室外机的运行能力可以相同,也可以不同。
在一些实施方式中,运行室外机时,先获取当前运行的室内机的容量数据,以确定出当前室内机具体的运行情况;进而可以根据室内机的运行情况,确定出室外机的运行目标,以准确地配合室内机的运行。例如,可以先采集当前系统中开机运行的室内机的总容量(记为Q)作为上述当前运行的室内机的容量数据,进而根据室内机的总容量,有针对性地确定出室外机组合方式,根据该组合方式运行室外机组中的室外机,以更好地配合室内机的运行,提高运行效能。
步骤S13:获取并根据室外机和室内机的历史运行数据,确定出与当前运行的室内机的容量数据匹配的多种室外机组合,其中,室外机组合的运行效能满足预设的能效要求。
在一些实施方式中,上述室外机和室内机的历史运行数据可以理解为:历史上在室外机和室内机协作运行时所记录的与室外机和室内机运行相关的参数数据。
在一些实施方式中,上述室外机和室内机的历史运行数据包括以下至少之一:室内机的历史容量数据、室外机的历史目标高压、室外机的历史目标低压、压缩机频率和风机频率。需要说明的是,上述所列举的运行数据只是为了更好地说明本公开实施方式。根据具体的应用场景和控制需求,还可以引入其他类型的参数数据作为上述室外机和室内机的历史运行数据。例如,还可以引入室内机和室外机中其他负载的开关状态作为上述室外机和室内机的历史运行数据。对此,本公开不作限定。
在一些实施方式中,上述获取室外机和室内机的历史运行数据,包括:在每次运 行室外机和室内机时,采集并保存本次运行的室外机和室内机的运行数据,作为后续再运行该方法步骤时室外机和室内机的历史运行数据。
在一些实施方式中,上述室外机组合可以理解为一种对应于一个周期的室外机组的运行方案。根据上述室外机组合可以确定出一个周期内参与运行的室外机,以及参与运行的室外机的运行顺序。上述室外机组合可以包含有一个室外机,例如1号室外机,表示在该周期内只运行1号室外机。上述室外机组合可以包含顺序排列的多个室外机,例如2号室外机、3号室外机、4号室外机,表示在该周期内先运行2号室外机,再运行3号室外机,最后运行4号室外机。需要说明的是,上述所列举的室外机组合只是一种示意性说明。根据具体的应用场景,还可以包含有其他形式的室外机组合。对此,本公开不作限定。
在一些实施方式中,上述根据室外机和室内机的历史运行数据,确定出与当前运行的室内机的容量数据匹配的多种室外机组合,包括:根据室内机的历史容量数据、室外机的历史目标高压、室外机的历史目标低压,确定历史换热量;根据压缩机频率、风机频率,确定历史消耗功率;根据历史换热量、历史消耗功率,确定历史能效数据;根据历史能效数据、当前运行的室内机的容量数据,确定出满足预设的能效要求的多种室外机组合,作为匹配的室外机组合。
在一些实施方式中,上述满足预设的能效要求的室外机组合,可以理解为:在一个周期中,按照顺序运行室外机组合中的各个室外机,如果整体的能源利用率大于或等于预设的能源利用率阈值,则该室外机组合为满足预设的能效要求的室外机组合。其中,上述预设的能源利用率阈值的具体数值可以根据具体的节能要求或者能效规则灵活设定。对此,本公开不作限定。
按照上述方式,通过参考历史能效数据,可以有针对性地确定出匹配当前运行的室内机的容量数据且具有较高能效的多种室外机组合。
在一些实施方式中,为了能够更加准确、高效地确定出前述匹配当前运行的室内机的容量数据且具有较高能效的多种室外机组合,还可以预先利用所获取的室外机和室内机的历史运行数据,通过学习训练,建立出对应的预设模型。其中,上述预设模型可以通过模型运算确定出与当前运行的室内机的容量数据匹配、且能量利用率大于或等于预设的能源利用率阈值的室外机组合。以当前运行的室内机的容量数据作为模型输入,输入进训练好的预设模型中,预设模型根据当前运行的室内机的容量数据进行模型运算,得到模型输出,从而获得上述多种匹配的室外机组合。
其中,上述利用所获取的室外机和室内机的历史运行数据,通过学习训练,建立出对应的预设模型,包括:将所获取的室外机和室内机的历史运行数据确定为用于模型训练的样本数据;根据室外机和室内机的历史运行数据,分别计算对应的能效利用率,并根据上述能效利用率标注对应的样本数据,得到标注后的样本数据;将标注后的样本数据不断地输入预设的神经网络模型进行多次的学习、训练,以建立得到上述预设模型。
需要说明的是,上述所列举的实现方式只是一种示意性说明。根据具体情况,也可以采用其他合适的方式来根据室外机和室内机的历史运行数据,确定出与当前运行的室内机的容量数据匹配的多种室外机组合。对此,本公开不作限定。
步骤S15:获取并根据预设时间段内的室外机的预设指标参数,确定室外机组合的优先级。
在一些实施方式中,上述步骤S15,包括以下步骤。
步骤S1:获取并根据预设时间段内的室外机的预设指标参数,确定室外机的健康度。
在一些实施方式中,上述预设时间段内的室外机的预设指标参数,可以理解为:一种能够反映室外机近段时间内的运行状态是否存在异常的指标参数。其中,上述预设的时间段可以是当前起向前一周内(即最近一周内)。上述所列举的预设时间段只是一种示意性说明。根据具体的精度要求还可以将其他时长的时间段作为上述预设的时间段。例如,还可以将当前起向前3天内(即最近3天内)所对应的时间段作为预设时间段等等。对此,本公开不作限定。
在一些实施方式中,上述预设时间段内的室外机的预设指标参数,包括以下至少之一:吸气过热度、排气温度、高压保护的触发次数和排气保护的触发次数。需要说明的是,上述所列举的预设指标参数只是为了更好地说明本公开实施方式。还可以引入其他能够反映室外机运行状态是否存在异常的参数数据作为上述预设指标参数。对此,本公开不作限定。
在一些实施方式中,上述获取预设时间段内的室外机的预设指标参数,包括:每次运行室外机时,记录并保存该次运行时室外机的预设指标参数,以及对应的记录时间;根据记录时间,获取并得到预设时间段内的室外机的预设指标参数。
在一些实施方式中,上述健康度可以理解为一种衡量当前室外机的运行状态的异常程度的参数数据。一个室外机的健康度的数值越低,则该室外机的异常程度越高, 运行时存在的可靠性风险越大。对应的,一个室外机的健康度的数值越高,则该室外机的异常程度越低,运行时存在的可靠性风险越小。
在一些实施方式中,上述根据预设时间段内的室外机的预设指标参数,确定室外机的健康度,包括:将初始健康度设置为100;统计在预设的时间段内,室外机的预设指标参数中大于等于预设参数阈值的预设指标参数的个数;将初始健康度减去上述大于等于预设参数阈值的预设指标参数的个数,得到的差作为室外机的健康度。
例如,每当统计到一个预设时间段内的室外机的吸气过热度大于等于预设的吸气过热度的参数阈值时,相应的将初始健康度数值减1。
需要说明的是,上述所列举的确定健康度的方式只是一种示意性说明。根据具体情况,也可以采用其他合适的方式来确定室外机的健康度。对此,本公开不作限定。
步骤S2:根据室外机的健康度,确定室外机组合的优先级。
在一些实施方式中,上述根据室外机的健康度,确定室外机组合的优先级,包括:根据每种室外机组合中所包含的室外机的健康度,来确定室外机组合的优先级。其中,上述室外机组合的优先级用于确定室外机组合运行的先后顺序。例如,一个室外机组合的优先级越高,该室外机组合按顺序靠前运行;对应的,一个室外机组合的优先级越低,该室外机组合按顺序靠后运行。
在一些实施方式中,可以统计每一种室外机组合中健康度小于等于健康度阈值的室外机的数量;根据每一种室外机组合中健康度小于等于健康度阈值的室外机的数量确定该室外机组合的优先级。例如,一个室外机组合中健康度小于等于健康度阈值的室外机的数量较多,则说明该室外机组合整体运行时相对存在的运行风险相对较高,因此可以将该室外机组合的优先级设置得相对较低;对应的,一个室外机组合中健康度小于等于健康度阈值的室外机的数量越小,则说明该室外机组合整体运行时存在的运行风险相对较低,因此可以将该室外机组合的优先级设置得相对较高。
进一步,对于每一种室外机组合而言,还可以根据该室外机组合中多个室外机的健康度,确定该室外机组合中不同室外机的运行顺序。例如,对于包含有1号室外机、2号室外机和3号室外机的室外机组合而言,其中1号室外机的健康度为95,2号室外机的健康度为92,3号室外机的健康度为75,基于上述3个室外机的健康度,可以按照健康度从高到低的顺序,确定该室外机组合的中室外机的运行顺序,即确定在该室外机组合中,先运行健康度最高的1号室外机,再运行健康度次之的2号室外机,最后运行健康度最低的3号室外机,从而可以提高该室外机组合整体运行的稳定性和 可靠性。
在一些实施方式中,在确定室外机组合时,还可以先根据前述室外机和室内机的历史运行数据得到各个室外机组合的能效数据,然后再确定各个室外机组合的优先级。例如,将室外机组合中的能效数据较高的室外机组合确定为优先级较高的室外机组合。之后,再根据室外机的健康度,对室外机组合的优先级进行调整,并将调整后的室外机组合的优先级确定为最终的室外机的优先级。该方案考虑到室外机组合的能效数据,可以提高室外机组的运行能效,达到节能运行的效果。
步骤S17:根据室外机组合的优先级,轮换运行多种室外机组合。
在一些实施方式中,上述步骤S17,包括:根据室外机组合的优先级,确定室外机组合的运行顺序;按照室外机组合的运行顺序,轮换运行多种室外机组合。
在一些实施方式中,可以根据室外机组合的优先级,多次轮换运行对应的室外机组合。对于多次轮换中的每一轮轮换,基于室外机组合的优先级确定运行顺序,然后再根据该运行顺序来运行各个室外机组合。
例如,在第一次轮换运行中,按照室外机组合的优先级,先运行优先级较高的室外机组合中的室外机,再运行优先级较低的室外机组合中的室外机,按顺序依次完成多种室外机组合的运行后,完成了第一次轮换运行。在完成第一次轮换运行后,检测当前室内机是否仍然处于运行状态,如果确定当前室内机仍然处于运行状态,开始第二次轮换运行,在第二次轮换运行中,可以按照第一次轮换运行中的运行顺序,按顺序运行多种室外机组合,完成第二次轮换运行。在完成第二次轮换运行后,检测当前室内机是否仍然处于运行状态,如果确定当前室内机没有处于运行状态,可以停止室外机运行;如果确定当前室内机仍然处于运行状态,可以按照上述方式继续进行第三次、第四次的轮换运行,直到室内机没有处于运行状态为止。
在本公开实施方式中,根据当前运行的室内机的容量数据、室外机和室内机的历史运行数据,来准确地确定出能针对性匹配且具有较高效能的室外机组合,从而提高了室外机的运行效能。此外,本公开基于根据室外机近期的预设指标参数所确定的室外机的健康度,来确定各个室外机组合的优先级,再按照室外机组合的优先级轮换运行室外机组合,提高了室外机组整体运行的稳定性,从而解决了相关技术方案存在的室外机组运行能效低、稳定性差的技术问题,达到高效、节能、稳定地运行室外机组的技术效果。
在一些实施例中,室外机和室内机的历史运行数据包括以下至少之一:室内机的 历史容量数据、室外机的历史目标高压、室外机的历史目标低压、压缩机频率和风机频率。需要说明的是,上述所列举的运行数据只是为了更好地说明本公开的实施方式。根据具体的应用场景,还可以引入其他类型的运行数据作为上述室外机和室内机的历史运行数据。对此,本公开不作限定。
在一些实施例中,上述根据室外机和室内机的历史运行数据,确定出与当前运行的室内机的容量数据匹配的多种室外机组合,包括:根据室内机的历史容量数据、室外机的历史目标高压、室外机的历史目标低压,确定历史换热量;根据压缩机频率、风机频率,确定历史消耗功率;根据历史换热量、历史消耗功率,确定历史能效数据;根据历史能效数据、当前运行的室内机的容量数据,确定出满足预设的能效要求的多种室外机组合,作为匹配的室外机组合。

基于上述室外机运行控制装置,本公开还提供了一种室外机运行控制设备,其中, 该设备包含有上述室外机运行控制装置所涉及的功能模块,以便能够实现对应的功能应用。
应用本公开提供的室外机运行控制方法和装置可以高效、节能地控制空调机组的室外机组稳定运行。图3所示为根据本公开一些实施例的室外机运行控制方法和装置的一些应用场景的示意图。在本场景示例中,所要控制的是空调机系统中由4个室外机并联组成的室外机组,以配合空调机系统的室内机组的运行。基于本公开实施方式所提供的方法可以先综合判断运行节能性、可靠性以及室外机的运行时间等多种因素,再对空调机组的运行进行有效、合理地轮换控制。
首先,可以根据当前开机的室内机容量(即当前运行的室内机的容量数据),确定出高能效组合(即满足预设的能效要求的室外机组合)。
可以先获取当前系统中开机运行的室内机的总容量Q,根据该数值确定满足:a0*Qcb≤Q≤b0*Qcb关系的对应室外机的容量,作为参考,其中0<a0<b0<1。
进一步,根据节能规则,来寻找具有高能效的组合。例如,先根据机组历史运行数据(即室外机和室内机的历史运行数据)进行自学习,确定出高能效组合。其中,上述机组历史运行数据包括:室内机的历史容量数据、室外机运行的目标高压、目标低压等一系列运行参数。进而可以根据上述运行参数计算出对应换热量(即历史换热量)。同时,还可以根据压缩机、风机频率以及系统高低压参数和其他负载的开关状态计算出机组的消耗功率情况(即历史消耗功率)。再结合换热量可以评估出历史运行数据对应的能效(即历史能效数据)。根据历史运行能效情况,确定不同开机内机容量下对应的高能效组合外机(即确定出满足预设的能效要求的室外机组合)。
还可以同时引入运行可靠性的判断。此处的运行可靠性又可以称为健康度,可以理解为一种结合机组运行时的吸气过热度、排气温度等参数以及高压保护、排气保护等异常保护次数等(即预设指标参数)对室外机机组的运行稳定性、可靠性进行评价的数据。
在本场景示例中,可以将近期运行过程(即预设时间段内)中各项参数指标均在正常的范围内,并且未出现过各种异常保护的室外机的健康度确定为100,若各项参数超出允许的正常范围,例如运行压力、排气温度等超出范围,或者出现过异常保护,例如排气高温保护等,则减少对应的分值,得到最后的差作为对应的健康度。
再根据健康度来确定优先级,按照以下的健康度评分的规则来确定对应的优先级: 若健康度≤T,则具有该室外机的轮换组合(即室外机组合)的优先级降为最低,并且当该轮换组合的累计运行时间达到a小时,则进其他组合的轮换。其中,正常的轮换周期为b小时,且a<b。在一些实施例中,例如,a设置为2,b设置为8,T设置为70。
运行室外机时,可以先按照上述方式根据当前开机内机容量和节能性判断规则,确定用于轮换的室外机组合的优先级。然后,根据健康度规则,例如,某个优先级中存在健康度≤70的室外机,则对应的室外机组合优先级降为最低。最终,机组按照上述确定的室外机组合的优先级依次进行轮换运行。
在场景示例中,设定每一个室外机组合的正常的轮换周期(即正常的运行时长)为8小时,即当某个组合累计运行时间达到8小时时,进行其他组合的轮换;当室外机组合中包括健康度≤70的室外机,则该组合累计运行时间达到2小时,就会进行其他组合的轮换。
通过上述场景示例,验证了应用本公开实施方式提供的室外机运行控制方法和装置的有益效果。根据当前运行的室内机的容量数据、室外机和室内机的历史运行数据,来准确地确定出能针对性匹配且具有较高效能的室外机组合,从而提高了室外机的运行效能。此外,本公开基于根据室外机近期的预设指标参数所确定的室外机的健康度,来确定各个室外机组合的优先级,再按照室外机组合的优先级轮换运行室外机组合,提高了室外机组整体运行的稳定性,从而解决了相关技术方案存在的室外机组运行能效低、稳定性差的技术问题,达到高效、节能、稳定地运行室外机组的技术效果。
