本公开涉及空调技术领域,具体涉及一种冷媒泄漏控制方法、装置、空调器、计算机可读存储介质、计算机程序产品和计算机程序。
本部分提供的仅仅是与本公开相关的背景信息,其并不必然是现有技术。
基于气候、建筑结构等方面因素的影响,现有市场中,如北美地区的一些空调器,将主要采用R454B冷媒取代R410A冷媒,而R454B冷媒为可燃冷媒,因此需要安装冷媒传感器进行冷媒泄露检测,当检测到冷媒泄露值超过冷媒泄漏保护阈值时室内机和室外机需要及时按照既定的保护程序响应。
相关技术中,北美地区的美式风管机通常多为室内机与室外机互不通讯,导致当室内机发生冷媒泄漏时,室外机无法响应保护程序。此外,北美市场多为替换市场,用户室内机、室外机不会一同更换,而是仅更换单独的室内机或室外机。但是,当用户需要更换新的产品时,现有控制方式无法实现冷媒泄露保护功能,用户不得不将室内机和室外机同时更换,导致更换成本较高。
发明内容
本公开的目的在于提供一种冷媒泄漏控制方法、装置、空调器、计算机可读存储介质、计算机程序产品和计算机程序,用以至少解决针对北美市场的美式风管机的室内机与室外机互不通讯,导致当室内机发生冷媒泄漏时,室外机无法响应保护程序的技术问题。该目的是通过以下技术方案实现的:
本公开的第一方面实施例提出了一种空调器的冷媒泄漏控制方法,所述空调器包括室内机和室外机,所述室外机内设有外风机和压缩机,所述室内机内设有内风机,所述空调器还包括内机通用转换板,所述内机通用转换板与所述室内机电连接,且所
述内机通用转换板设有与压缩机电连接的第一通信端口,所述空调器的冷媒泄漏控制方法包括:
获取所述室内机的冷媒泄漏浓度;和
根据所述室内机的冷媒泄漏浓度大于或等于预设泄漏保护阈值,控制所述内风机以预设风档运行,并控制所述内机通用转换板通过所述第一通信端口向所述室外机输出压缩机停机信号,以使所述压缩机被停机。
根据本公开实施例提供的空调器的冷媒泄漏控制方法,通过增加设置线控器和与线控器通信连接的内机通用转换板,内机通用转换板与室内机通信连接,且内机通用转换板设置有与室外机通信连接的第一通信端口,从而使得室外机能够通过第一通信端口与室内机通信连接,进而可在室内机发生冷媒泄漏,且冷媒泄漏浓度超过预设泄漏保护阈值的情况下,室外机能够及时执行冷媒保护程序,以降低室内机发生引燃或爆炸的风险。
具体地,通过实时获取室内机的冷媒泄漏浓度,冷媒泄漏浓度可通过室内机内设置的冷媒传感器进行监测,当冷媒泄漏浓度大于或等于预设泄漏保护阈值时,室内机具有发生引燃或爆炸的安全风险,此时通过控制内风机以预设风档强制运行,从而将室内机内的冷媒吹向室内,以降低室内机的冷媒浓度。同时,控制内机通用转换板通过第一通信端口向室外机输出压缩机停机信号,使压缩机被强制停机,从而使得压缩机无法继续向室内机提供冷媒,以使室内机内的冷媒泄漏浓度在内风机的运转下快速降低,进而降低室内机发生引燃或爆炸的风险。同时,由于增加了内机通用转换板,使得室内机能够通过内机通用转换板适配不同类型的室外机,从而可在室外机需要更换时,无需更换室内机,有助于降低产品的更换成本。
可以理解的,室内机能够向线控器输出供电信号,线控器与内机通用转换板通信连接,从而使内机通用转换板能够接收和输出压缩机停机信号。此外,线控器还可以通过内机通用转换板向室内机输出内风机启动信号。

请参见图1,本公开的第一方面提出了一种空调器的冷媒泄漏控制方法,空调器包括室内机和室外机,室外机内设有外风机和压缩机,室内机内设有内风机,空调器还包括内机通用转换板,内机通用转换板与室内机电连接,且内机通用转换板设有与压缩机电连接的第一通信端口,空调器的冷媒泄漏控制方法包括步骤S10至S30。
步骤S10:获取室内机的冷媒泄漏浓度。
步骤S20:判断室内机的冷媒泄漏浓度是否大于或等于预设泄漏保护阈值。
步骤S30:根据室内机的冷媒泄漏浓度大于或等于预设泄漏保护阈值,控制内风机以预设风档运行,并控制内机通用转换板通过第一通信端口向室外机输出压缩机停机信号,以使压缩机被停机。
在本实施例中,本公开实施例提供的空调器的冷媒泄漏控制方法,通过增加设置线控器和与线控器通信连接的内机通用转换板,内机通用转换板与室内机通信连接,且内机通用转换板设置有与室外机通信连接的第一通信端口,从而使得室外机能够通过第一通信端口与室内机通信连接,进而可在室内机发生冷媒泄漏,且冷媒泄漏浓度超过冷媒泄漏保护阈值的情况下,室外机能够及时执行冷媒保护程序,以降低室内机发生引燃或爆炸的风险。
具体地,通过实时获取室内机的冷媒泄漏浓度,室内机的冷媒泄漏浓度可通过室内机内设置的冷媒传感器进行监测,基于冷媒泄漏浓度大于或等于预设泄漏保护阈值,通过控制内风机以预设风档强制运行将室内机内的冷媒吹向室内,以降低室内机的冷媒浓度,并且控制内机通用转换板通过第一通信端口向室外机输出压缩机停机信号,使压缩机被强制停机,从而使得压缩机无法继续向室内机提供冷媒,以使室内机内的冷媒泄漏浓度在内风机的运转下快速降低,进而降低室内机发生引燃或爆炸的风险,并且
由于增加了内机通用转换板,使得室内机能够通过内机通用转换板适配不同类型的室外机,从而可在室外机需要更换时,无需更换室内机,有助于降低产品的更换成本。
可以理解的,室内机能够向线控器输出供电信号,线控器与内机通用转换板通信连接,从而使内机通用转换板能够接收和输出压缩机停机信号。此外,线控器还可以通过内机通用转换板向室内机输出内风机启动信号。
请参见图2,根据本公开的一些实施例,空调器的冷媒泄漏控制方法还包括:
步骤S40:根据室内机的冷媒泄漏浓度小于预设泄漏保护阈值,控制内机通用转换板通过第一通信端口向室外机保持输出压缩机运行信号,以使压缩机维持当前运转状态。
在本实施例中,可以理解的,室内机的冷媒泄漏浓度小于预设泄漏保护阈值说明室内机不存在冷媒泄漏的情况,或者冷媒泄漏浓度较小,此时未触发冷媒泄漏保护程序,则控制内机通用转换板通过第一通信端口保持输出压缩机运行信号,使压缩机维持当前运转状态,并且使内风机维持当前风档运行。
请参见图3,根据本公开的一些实施例,在获取所述室内机的冷媒泄漏浓度的步骤之后,所述空调器的冷媒泄漏控制方法还包括:
步骤S50:根据室内机的冷媒泄漏浓度大于或等于预设报警阈值,控制开启报警状态;
其中,预设报警阈值小于预设泄漏保护阈值。
在本实施例中,示例性地,空调器还包括报警装置,报警装置可以为采用语音播报形式或发射警示灯光的报警器等。
值得说明的是,开启报警状态时室内机的冷媒泄漏浓度低于预设泄漏报警阈值,用以及时提醒操作人员对室内机进行检查和维修。响应于获取到室内机的冷媒泄漏浓度达到预设泄漏保护阈值,立即控制开启冷媒泄漏保护程序。响应于冷媒泄漏浓度再次降低至小于预设泄漏保护阈值,控制报警装置关闭报警状态。
根据本公开的一些实施例,控制内风机以预设风档运行的步骤中,预设风档为内风机的最高风档。
请参见图4,根据本公开的一些实施例,空调器的冷媒泄漏控制方法还包括:
步骤S60:控制外风机运转至预设时长。
在本实施例中,示例性地,预设时长可以设置在3分钟至15分钟的范围内。
压缩机在运转过程中会产生较大热量,当压缩机突然停机后,室外机的温度仍然较高,此时通过控制外风机持续运转预设时长,例如,继续运转5分钟、10分钟或15
分钟,以保持对室外机进行压缩机停机后的持续散热,待运转至预设时长后再控制外风机停止运转,从而有助于保障室外机内如压缩机、室外换热器等各设备件的使用性能。
本公开第一方面实施例提供了一种空调器的冷媒泄漏控制方法,适用于上述任一实施例的空调器,其中,空调器的冷媒泄漏控制方法包括:
获取室内机的冷媒泄漏浓度;
根据室内机的冷媒泄漏浓度大于或等于预设泄漏保护阈值,控制启动报警状态;和
根据室内机的冷媒泄漏浓度小于预设泄漏保护阈值,控制内机通用转换板通过第一通信端口向室外机保持输出压缩机待机或运行信号,以使压缩机维持当前运转状态。
请参见图10,本公开第二方面实施例提供了一种空调器100的控制装置200,包括:存储器220和处理器210,存储器220被配置为存储计算机程序,计算机程序被处理器210执行时实现如第一方面任一实施例的空调器100的冷媒泄漏控制方法的步骤。
请参见图5和图9,本公开第三方面实施例提供了一种空调器100,包括室内机110、室外机130、线控器120、内机通用转换板140、冷媒传感器150、报警器160和第二方面任一实施例所述的控制装置200。
其中,室外机130内设有外风机和压缩机,室内机110内设有内风机111;内机通用转换板140分别与室内机110和线控器120通信连接,且内机通用转换板140设有与压缩机电连接的第一通信端口15;冷媒传感器150和报警器160,设于室内机110内;控制装置200与线控器120、内机通用转换板140、外风机、压缩机、内风机111和冷媒传感器150电连接,用于执行计算机程序时实现如第一方面任一实施例的空调器100的冷媒泄漏控制方法。
在本实施例中,线控器120和室外机130也设有第一通信端口15,线控器120的第一通信端口15与内机通用转换板140上的第一通信端口15通信连接,内机通用转换板140上的第一通信端口15与室外机130上的第一通信端口15通信连接,取消了线控器120与室外机130之间的信号线。
可以理解的,第一通信端口15为压缩机启停信号端口。
在一些实施例中,内机通用转换板140还设有冷媒传感器信号端口17,冷媒传感器信号端口17与冷媒传感器150电连接。室内机110、内机通用转换板140、线控器120和室外机130均设有内风机启动信号端口13,内风机启动信号端口13之间通信连接。
基于冷媒传感器150保护程序未触发,线控器120发出的信号由内机通用转换板
140中转后发送到室内机110的控制板上,并且内机通用转换板140将线控器120发出的压缩机运行信号发送到室外机130,此时室内机110、室外机130均可正常运行。基于冷媒传感器150检测到冷媒泄露浓度达到冷媒泄漏保护阈值,控制报警器160启动报警,并控制内风机111以预设风档强制运行,并且向室外机130输出压缩机停机信号,使得压缩机停止运行,从而实现在冷媒泄露浓度达到冷媒泄漏保护阈值时,室外机130的压缩机能够自动停机保护。
参见图6,根据本公开的一些实施例,线控器120、内机通用转换板140、室内机110和室外机130均设有公共端口12,线控器120上的公共端口12与内机通用转换板140上的公共端口12之间通信连接,内机通用转换板140上的公共端口12与室外机130上的公共端口12之间通信连接。
根据本公开的一些实施例,线控器120、内机通用转换板140、室内机110和室外机130均设有除霜信号端口16,线控器120和室外机130上的除霜信号端口16与内机通用转换板140上的除霜信号端口16之间通信连接。
根据本公开的一些实施例,线控器120、内机通用转换板140、室内机110和室外机130均设有四通阀换向信号端口14,线控器120和室外机130上的公共端口12与内机通用转换板140上的四通阀换向信号端口14之间通信连接。
根据本公开的一些实施例,室内机110、内机通用转换板140和线控器120均设有供电信号端口11,供电信号端口11之间通信连接。
在本实施例中,为便于说明,记除霜信号端口16为W,四通阀换向信号端口14为B,供电信号端口11为R,内风机111启动信号为G,公共端口12为C,第一通信端口15为Y。
内机通用转换板140上进一步增加W、B、C端口,并通过信号线将内机通用转换板140的W、Y、B、C端口与室外机130W、Y、B、C端口连接,并且取消线控器120与室外机130之间的W、Y、B、C信号线。此时室外机130的Y、B信号由内机通用转换板140提供,C为公共端,除霜模式条件下,室外机130的W信号发送到内机通用转换板140,再由内机通用转换板140发送到室内机110。基于冷媒泄漏保护程序未触发,线控器120经过内机通用转换板140向内机发送的Y、G、B信号保持当前状态(持续发送或断开),内风机111保持当前状态(运行或停机),并且内机通用转换板140向室外机130发送的Y、B信号也保持当前状态(持续发送或断开)。基于冷媒泄露保护程序将处于触发状态,无论线控器120是否经过内机通用转换板140向室内机110发送Y、G、B信号,内风机111均按保护程序设定的风档强制运行,内机通用转换板140均控制内风机111按保护程序设定的风档强制运行,并且内机通用转换
板140强制向室外机130输出压缩机停机信号,压缩机被强制停机。
在一些实施例中,参见图7,线控器120、内机通用转换板140和室外机130均设置有第一运行频率信号端口151和第二运行频率信号端口152,线控器120与内机通用转换板140上的第一运行频率信号端口151之间通信连接,内机通用转换板140与室外机130上的第一运行频率信号端口151之间通信连接,线控器120与内机通用转换板140上的第二运行频率信号端口152之间通信连接,内机通用转换板140与室外机130上的第二运行频率信号端口152之间通信连接。
在本实施例中,压缩机为双级压缩机,双级压缩机可以是由两台压缩机组成,也可以是由一台压缩机组成的单机两级系统,其中一个或两个汽缸作为高压缸,其余几个汽缸作为低压缸。即空调器100具有双级压缩机制冷循环功能,其是指来自蒸发器的制冷剂要经过低压与高压压缩机两次压缩后,才进入冷凝器。并在两次压缩中间设置中间冷却器。
为便于说明,记第一运行频率信号端口151和第二运行频率信号端口152分别为Y1和Y2。
示例性地,Y1用于输出压缩机低频运行信号,Y2用于输出压缩机高频运行信号。也就是说,响应于室外机130接收到Y1信号,压缩机按低频运行,响应于室外机130接收到Y1和Y2信号,压缩机以高频运行。
基于冷媒泄漏保护程序未触发,线控器120经过内机通用转换板140向室内机110发送的Y1、Y2、G、B信号保持当前状态(持续发送或断开),内风机111保持当前状态(运行或停机),并且内机通用转换板140向室外机130发送的Y1、Y2、B信号也保持当前状态(持续发送或断开)。基于冷媒泄露保护程序处于触发状态,无论线控器120是否经过内机通用转换板140向室内机110发送Y1、Y2、G、B信号,内风机111均按保护程序设定的风档强制运行,并且内机通用转换板140通过第一通信端口15向室外机130输出压缩机停机信号,或输出断开Y1+Y2信号,压缩机被强制停机。
参见图8,根据本公开的一些实施例,内机通用转换板140上仅设有第一运行频率信号端口151与第二运行频率信号端口152,室外机130上的第一运行频率信号端口151与第二运行频率信号端口152对应与内机通用转换板140上的第一运行频率信号端口151与第二运行频率信号端口152通信连接,并与线控器120上的第一运行频率信号端口151与第二运行频率信号端口152保持断开。
基于冷媒泄漏保护程序未触发,内风机111保持当前状态(运行或停机),线控器120经过内机通用转换板140向室内机110发送的Y1、Y2、G、B信号保持当前状
态(持续发送或断开),内电机保持当前状态(运行或停机),并且内机通用转换板140向室外机130发送的Y1、Y2信号也保持当前状态(持续发送或断开)。基于冷媒泄露保护程序处于触发状态,此时无论线控器120是否经过内机通用转换板140向室内机110发送Y1、Y2、G、B信号,内风机111均按照保护程序设定的风档强制运行,并且内机通用转换板140通过第一通信端口15向室外机130输出压缩机停机信号,或并且输出断开Y1+Y2信号,压缩机被强制停机。
本公开第四方面实施例提供了一种计算机可读存储介质,计算机可读存储介质上存储有计算机程序,计算机程序被处理器210执行时实现如第一方面任一实施例的空调器100的冷媒泄漏控制方法。
本公开第五方面实施例提供了一种计算机程序产品,包括计算机程序,所述计算机程序在被处理器执行时实现上述第一方面任一实施例的空调器的冷媒泄漏控制方法。
本公开第六方面实施例提供了一种计算机程序,包括计算机程序代码,当所述计算机程序代码在计算机上运行时,使得所述计算机执行上述第一方面任一实施例的空调器的冷媒泄漏控制方法。
需要说明的是,前述实施例对空调器的冷媒泄漏控制方法和装置的解释说明也适用于本公开实施例的计算机可读存储介质、计算机程序产品和计算机程序,此处不再赘述。
本公开所有实施例均可以单独被执行,也可以与其它实施例相结合被执行,均视为本公开要求的保护范围。
以上所述,仅为本公开较佳的具体实施方式,但本公开的保护范围并不局限于此,任何熟悉本技术领域的技术人员在本公开揭露的技术范围内,可轻易想到的变化或替换,都应涵盖在本公开的保护范围之内。因此,本公开的保护范围应以权利要求的保护范围为准。
