如果室外机内存在一个室外风机A,若该室外风机A故障,则禁止该室外机运行,整个空调系统停止运行;若该室外风机A无故障,则室外风机A进入正常运转控制,整个空调系统正常运行。
如果室外机内存在两个室外风机A1和A2,若室外风机A1和A2均故障时,则禁止该室外机运行,整个空调系统停止运行;若室外风机A1和A2均无故障,则室外风机A1和A2分别进入正常运转控制,整个空调系统正常运行;若室外风机A1和A2中一个室外风机故障,则有故障的室外风机进入应急运转控制,即禁止该室外风机运转,无故障的室外风机进入正常运转控制,整个空调系统正常运行。
此处所说的正常运转控制与现有空调器中控制室外风机运转的方式无异,可参考现有空调器控制室外风机的方式获知,例如,可以按照室外机压缩机频 率、吸排气压力、温度等参数周期性地控制室外风机的转速,并实时监测室外风机的运转状态、故障信息等。
如图1所示,本实施例空调室外机主要包括风机状态获取模块11、运转控制模块12和机组状态获取模块13。
本实施例风机状态获取模块11用于获取各室外风机的运转状态,此处的运转状态包括室外风机有故障时的应急运转状态和室外风机无故障时的正常运转状态。
具体地,设置有系统初始化模块14,用于获取当前室外机中室外风机的数量以配置确定机组种类,包括单风机室外机组和多风机室外机组。
本实施例中,以双风机室外机组为例说明多风机室外机组。
并且,为了保证室外风机在应急运转时的控制,系统初始化模块14还会初始化应急运转用状态标识变量,例如计数变量、计时变量等,其中计数变量用于计数当前室外机中所具有室外风机的数量,计时变量用于计时室外机在应急运转时的应急运转时间。
在本实施例中,风机状态获取模块11基于所确定的机组种类(单风机室外机组或多风机室外机组)判定相应室外风机的运转状态。
在本实施例中,室外风机的运转状态可以通过如下方式进行设定。
在室外机运行过程中,一旦发现存在室外风机故障,则对应将该室外风机的运转状态设定为应急运转状态,此种设定可以通过风机状态设定模块(未示出)设定,例如人工拨码设定。
当然,此种设定也可以采取其他软件程序自动识别室外风机的故障情况,并将具有故障的室外风机的运转状态设定为应急运转状态,等等。
本实施例运转控制模块12用于根据室外风机的运转状态,控制室外风机执行正常运转控制或应急运转控制。应急运转状态对应应急运转控制,正常运转状态对应正常运转控制。
在采集到该室外风机的运转状态为应急运转状态时,针对该室外风机,则进入应急运转控制。在采集到该室外风机的运转状态为正常运转状态时,针对该室外风机,则进入正常运转控制。
对于单风机室外机组来说,存在如下两种情况:1)室外风机A的运转状态为正常运转状态时,单风机室外机组正常运行;2)室外风机A的运转状态为应急运转状态时,禁止单风机室外机组运行。
对于双风机室外机组来说,存在如下三种情况:1)室外风机A1和A2的运转状态均为正常运转状态时,双风机室外机组正常运行;2)室外风机A1和A2的运转状态均为应急运转状态,禁止双风机室外机组运转;3)室外风机A1和A2中之一的运转状态为正常运转状态,而室外风机A1和A2中另一个的运转状态为应急运转状态,应急运转状态的室外风机进入应急运转控制,而正常运转状态的室外风机转入正常运转控制。
本实施例机组状态获取模块13根据运行的室外机,获取机组运行参数,例如吸排气压力、温度等参数。
如上所述的系统初始化模块14还会初始化机组运行参数,例如室外机压缩机吸排气压力、温度等参数。
对于具有进入正常运转控制的室外风机的室外机(即运行的室外机),通过设置的异常控制模块15实时监测机组运行参数,例如吸排气压力、温度等参数,实时监测空调室外机运行状态。
例如一旦吸排气压力超过压力限值或温度超过温度限值,为避免影响空调系统可靠性,则空调系统停机,否则,空调器继续运行并继续对室外机运行情状态进行监控。
为了避免在双风机室外机组的第3)种情况下有故障的室外风机的相关故障影响系统运行,系统不再监测该室外风机的异常信息。
此外,为了防止室外机长时间处于应急运转中影响系统可靠性,在本实施例中,系统设置有应急运转时间阈值,在所计时的室外机进入应急运转时的应急运转时间超过应急运转时间阈值时,则空调系统停机,以等待恢复重试状态。
其中室外机进入应急运转是指室外机处于如上所述的双风机室外机组的第3)中情况。
本申请提供的空调室外机,在单室外机存在多室外风机时,在室外机中的一部分室外风机故障时,通过对有故障的室外风机进行应急运转控制,而对无故障的室外风机进行正常运转控制,实现及时存在室外风机故障时,空调器在一段时间内也能正常运行,延长空调器的使用时间,减少在室外风机故障时用户不能使用空调器的抱怨,提升用户使用体验;且为申请及调配备件赢得一定时间,提升服务质量。
