下面参考附图描述本发明实施例的空调器及其自清洗控制方法、装置和存储介质。
在描述本发明实施例的空调器及其自清洗控制方法、装置和存储介质之前,对本发明实施例的空调器结构进行说明。
如图1所示,本发明实施例的空调器包括空调压缩机101、四通换向阀102、室外换热器103、电子膨胀阀104(下文为节流装置)、室内换热器105和高压检测阀106,其中,高压检测阀106设置于空调压缩机101和四通换向阀102之间,以获取排气口的高压侧压力,其余结构与现有技术空调器之中的工作原理相同或相似,在此不再赘述。
图2为根据本发明实施例的空调器的自清洗控制方法的流程示意图。
如图2所示,空调器的自清洗控制方法,包括以下步骤:
S101,在空调器进入自清洗模式时,控制空调器进行制冷运行。
可选地,用户可通过空调器遥控器或移动终端上的APP控制空调器进入自清洗模式。
S102,在空调器进行制冷运行的过程中,获取压缩机排气口的高压侧压力,记录空调器进行制冷运行的时间。
也就是说,在空调器进行制冷运行的过程中,可通过上述设置于空调压缩机和四通换向阀之间的高压检测阀获取压缩机排气口的高压侧压力P,以及,记录空调器进行制冷运行的时间SL,进而,根据高压侧压力P和空调器制冷运行的时间SL,判断是否控制空调器切换到制热运行。
S103,根据高压侧压力和空调器进行制冷运行的时间控制空调器切换到进行制热运行。
具体地,在本发明的实施例中,如图3所示,根据高压侧压力和空调器进行制冷运行的时间控制空调器切换到进行制热运行,包括:
S201,判断高压侧压力是否大于等于第一压力阈值或者空调器进行制冷运行的时间是否大于等于第一时间阈值。
可选地,第一压力阈值P1和第一时间阈值S1可根据空调器的参数进行相应的设定,例如,在本发明的实施例中,第一压力阈值P1可设置为5.5Mpa,第一时间阈值S1可设置为10min。
S202,如果高压侧压力大于等于第一压力阈值或者空调器进行制冷运行的时间大于等于第一时间阈值,则控制空调器切换到进行制热运行。
也就是说,当高压侧压力P大于等于第一压力阈值P1或者空调器进行制冷运行的时间SL大于等于第一时间阈值S1,例如P≥5.5Mpa或者SL≥10min时,可认为空调器制冷运行过程中的结霜程度达到空调器的自清洗需求,此时,可控制空调器切换到进行制热运行,进入化霜自清洗过程。
应理解的是,若高压侧压力P和空调器进行制冷运行的时间SL未满足控制空调器切换到进行制热运行的条件,则可控制空调器维持制冷运行,以控制空调器继续结霜。
S104,在空调器进行制热运行的过程中,获取室外换热器底部的温度,记录空调器进行制热运行的时间。
可选地,在空调器进行制热运行的过程中,可通过设置在室外换热器底部的温度传感器,获取室外换热器底部的温度T,并记录空调器进行制热运行的时间SR,进而,根据室外换热器底部的温度T和空调器进行制热运行的时间SR,判断是否控制空调器退出自清洗模式。
S105,根据室外换热器底部的温度和空调器进行制热运行的时间控制空调器退出自清洗模式。
具体地,在本发明的实施例中,如图4所示,根据室外换热器底部的温度和空调器进行制热运行的时间控制空调器退出自清洗模式,包括:
S301,判断室外换热器底部的温度是否大于等于第一温度阈值或者空调器进行制热运行的时间是否大于等于第二时间阈值。
可选地,第一温度阈值T1和第二时间阈值S2可根据空调器的运行参数进行相应的设定,例如,在本发明的实施例中,第一温度阈值T1可设置为18℃,第二时间阈值S2可设置为10min。
S302,如果室外换热器底部的温度大于等于第一温度阈值或者空调器进行制热运行的 时间大于等于第二时间阈值,则控制空调器退出自清洗模式。
也就是说,当室外换热器底部的温度T大于等于第一温度阈值T1或者空调器进行制热运行的时间SR大于等于第二时间阈值S2,例如T≥T1或SR≥S2时,可认为空调器已完成化霜自清洗,此时,控制空调器退出自清洗模式。
应理解的是,若室外换热器底部的温度T或空调器进行制热运行的时间SR未满足控制空调器退出自清洗模式的条件,则可控制空调器维持制热运行,以控制空调器继续进行化霜自清洗。
进一步地,在本发明的实施例中,在控制空调器进行制冷运行的过程中,还控制压缩机以第一频率运行,控制节流装置以第一开度打开,控制室内风机和室外风机停止运行。
应理解的是,在控制空调器进行制冷运行的过程中,通过控制压缩机以第一频率运行,控制节流装置以第一开度打开,控制室内风机和室外风机停止运行,以控制空调器进行结霜。
可选地,第一频率和第一开度可根据空调器的运行参数进行相应的设定,例如,第一频率可设置为70hz,第一开度可设置为节流装置最大开度的五分之一。
进一步地,在本发明的实施例中,在控制空调器进行制热运行的过程中,还控制压缩机以第二频率运行,控制节流装置以第二开度打开,控制室内风机停止运行,控制室外风机以第一转速运转。
应理解的是,在控制空调器进行制热运行的过程中,通过控制压缩机以第二频率运行,控制节流装置以第二开度打开,控制室内风机停止运行,控制室外风机以第一转速运转,以控制空调器进行化霜自清洗。
可选地,第二频率、第二开度和第一转速可根据空调器的运行参数进行相应的设定,第二频率可设置为70hz,第二开度可设置为节流装置最大开度的三分之一,第二转速可设置为850rad/min。
可以理解的是,在本发明的实施例中,第二开度大于第一开度。
下面结合附图5与本发明的具体实施例,对本发明的空调器的自清洗控制方法做进一步的说明,用户选择空调器运行自清洗模式之后,执行步骤S1。
S1,在空调器进入自清洗模式时,控制空调器进行制冷运行。
S2,控制压缩机以第一频率运行,控制节流装置以第一开度打开,控制室内风机和室外风机停止运行。
S3,获取压缩机排气口的高压侧压力P,记录空调器进行制冷运行的时间SL。
可选地,可每隔10秒检测一次压缩机排气口的高压侧压力P。
S4,判断高压侧压力P是否大于等于第一压力阈值P1或空调器进行制冷运行的时间 SL是否大于等于第一时间阈值S1,如果是,则执行步骤S5;如果否,则执行步骤S2。
S5,控制空调器切换到进行制热运行。
S6,控制压缩机以第二频率运行,控制节流装置以第二开度打开,控制室内风机停止运行,控制室外风机以第一转速运转。
S7,获取室外换热器底部的温度T,记录空调器进行制热运行的时间SR。
