具体实施方式
现在将参照附图对示例实施方式进行更全面地描述。
提供了示例实施方式以使得本公开是彻底的并将向本领域技术人员全面地传达本公开的范围。阐述了许多诸如特定部件、装置以及方法的示例的许多的具体细节，以提供对本公开的实施方式的全面理解。对本领域技术人员而言将明显的是不必采用特定细节，示例性实施方式可以以许多不同的形式实施，并且任何一者都不应被解释为限制本公开的范围。在一些示例实施方式中，对众所周知的过程、众所周知的装置结构、以及众所周知的技术没有进行详细描述。
本文所使用的专业术语仅出于描述特定示例实施方式的目的，并不意在是限制性的。如本文所使用的，除非上下文另外清楚地指明，否则单数形式“一”，“一个”和“该”可以意在也包括复数形式。术语“包括”、“包含”、“包括有”以及“具有”是开放性的，并因此指定所陈述的特征、整数、步骤、操作、元件和/或部件的存在，但并不排除存在或添加一个或更多个其他特征、整数、步骤、操作、元件、部件和/或它们的组。除非特别表明按执行顺序执行，否则文中所述的方法步骤、流程和操作不应被解释为必须要求它们按讨论的或示出的特定顺序来执行。还应当理解的是可以采用附加的步骤或替代性步骤。
当元件或层被称为“在另一元件或层上”、“接合至”、“连接至”，或“联接至”另一元件或层时，该元件或层可直接在另一元件或层之上、接合、连接或联接至另一元件或层，或者可以存在居间元件或层。相反，当元件被称为“直接在另一元件或层上”、“直接接合至”、“直接连接至”或“直接联接至”另一元件或层时，可以不存在居间元件或层。用于描述元件之间关系的其他词语应该以相同的方式理解(例如，“在…之间”与“直接在…之间”、“相邻于”与“直接相邻于”等)。如本文所使用的术语“和/或”包括关联列举的项中的一个或更多个项的任意及所有组合。
尽管可以在本文中使用术语第一、第二、第三等来描述各个元件、部件、区域、层和/或部段，但这些元件、部件、区域、层和/或部段不应该受这些术语的限制。这些术语可仅用于将一个元件、部件、区域、层或部段与另一区域、层或部段区分开。诸如“第一”、“第二”和其他数值的术语在本文中使用时不意味着次序或顺序，除非上下文明确指示。因此，在不脱离示例实施方式的教示的情况下，下文讨论的第一元件、部件、区域、层或部段可以称为第二元件、部件、区域、层或部段。
出于易于说明的目的，本文中可以使用诸如“内”、“外”、“在…下面”、“在…下方”、“下”、“在…上方”、“上”等空间相关术语以描述图中所示的一个元件或特征与另一元件或特征的关系。空间相关术语可以意在涵盖装置在使用或操作中的除图中所描绘的取向之外的不同取向。例如，如果图中的装置被翻转，则被描述为“在其他元件或特征的下方”或“在其他元件或特征的下面”的元件将被定向成“在其他元件或特征的上方”。因而，示例术语“在…下方”可涵盖“在…上方”和“在…下方”这两个取向。该装置可以以其他方式定向(旋转90度或处于其他取向)，并且文中使用的空间相关描述词被相应地解释。
参照图1，提供了热泵系统10，该热泵系统10可以包括压缩机12、换向阀14、室内热交换器16、膨胀装置18以及室外热交换器20。压缩机12可以是例如涡旋式压缩机、往复式压缩机或旋叶式压缩机，或者可以是任意其他类型的压缩机。换向阀14可以是能够操作成控制工作流体流过热泵系统10的方向的四通阀。控制器(未示出)可以使换向阀14在对应于冷却模式的第一位置(未示出)与对应于加热模式的第二位置(在图1中示出)之间切换。
在冷却模式中，例如，室外热交换器20可以操作为冷凝器或气体冷却器并且可以通过将热从工作流体传递至环境空气来冷却从压缩机12接收的排出压力工作流体。在加热模式中，室外热交换器20可以操作为蒸发器。
在冷却模式下，室内热交换器16可操作为蒸发器并且可以将热从待被冷却的空间(例如房屋或建筑物内的房间)传递至室内热交换器16内的工作流体。在加热模式下，室内热交换器16可以操作为冷凝器或气体冷却器并且可以将热从由压缩机12排出的工作流体传递至待被加热的空间。在热泵系统10的操作期间，风扇22可以经由回气管24从待被加热或冷却的空间抽吸空气，并迫使该空气穿过室内热交换器16以在室内热交换器16内的工作流体与空气之间传递热。经加热或经冷却的空气可通过供气管道26从室内热交换器16被迫至待被加热或被冷却的空间。
热泵系统10也可以包括回气温度传感器30、供气温度传感器32、液体管线温度传感器34、以及外部空气温度传感器38。回气温度传感器30可以布置在回气管24内并且可以测量流动通过回气管24的空气的温度。供气温度传感器32可以布置在供气管26内并可测量流经供气管26的空气的温度。液体管线温度传感器34可以布置在室内热交换器16与膨胀装置18之间并可测量在室内热交换器16与膨胀装置18之间流动的工作流体的温度。外部空气温度传感器38可以布置在任意适当的位置用以测量房屋或建筑物外部的环境空气的温度。
如图2所示，传感器30、32、34、38可以与远程定位或定位在现场的处理装置40通信。在一些实施方式中，传感器30、32、34、38中的任意传感器或所有传感器可以安装在上述位置中。在一些实施方式中，传感器30、32、34、38中的任意传感器或所有传感器可以是可以由技术人员暂时放置在上述位置中、在这些位置中获得温度测量值并将数据传输至处理装置40的手持传感器。传感器30、32、34、38中的任意传感器或所有传感器可以结合至新安装的热泵系统中，或传感器30、32、34、38中的任意传感器或所有传感器可以针对已经安装在房屋或建筑物内的预先存在的热泵系统而被改造。在一些配置中，外部空气温度传感器38可以是天气监测和/或天气预报系统或实体中的温度计或其他传感器。在这种配置中，处理器40可以经由例如因特网、(蓝牙)或蜂窝连接从由天气监测和/或天气预报系统或实体中的传感器38测量的外部空气温度。
处理装置40可以包括具有能够执行下述功能的硬件(例如，处理器和/或存储器)和软件的云计算模块。处理装置40可以与服务器通信，服务器例如可以通过网络连接或蜂窝网络接收来自传感器30、32、34、38的数据。处理装置40可以按需、间歇地或实时地从传感器30、32、34、38接收数据。在一些实施方式中，处理装置40可以位于承包商或技术人员的便携式计算装置(例如，笔记本电脑、平板电脑、智能手机或其他装置)上，或者位于安装有热泵系统10的房屋或建筑物内(例如在用于热泵系统10的恒温器(未示出)或控制模块(未示出)中)。
处理装置40可以同样与布置成远离处理装置40和/或传感器30、32、34、38的一个或更多个通知装置42通信。通知装置42可以包括例如台式计算机、笔记本电脑、手提式计算机装置、平板电脑或智能手机中的任意者，或者可以包括任意其他计算装置或电子信息显示装置。在一些实施方式中，所述一个或更多个通知装置42可以是壁安装式恒温器单元的一部分。
如接下来将描述的，处理装置40可以：基于从一个或更多个传感器30、32、34、38接收的数据来诊断热泵系统10的故障状态(例如未充注状态、过充状态和/或限流状态)，证实热泵系统10的充注水平，和/或在热泵系统10的初始安装期间为技术人员提供指导以便将适量的工作流体添加至热泵系统10内。从处理装置40输出的通知、警报、更新和/或其他的信息可以被传输至一个或更多个通知装置42并可被访问或在其上显示。在一些实施方式中，从处理装置40输出的通知、警报、更新和/或其他信息可以经由电子邮件、文本信息、即时信息、多媒体信息传输至通知装置42。在一些实施方式中，通知装置42可以包括基于来自处理装置40的输出来提供通知、警告、更新、和/或其他信息的移动应用(例如，智能手机或平板电脑应用)。
参照图1至图3，将详细描述当热泵系统10处于加热模式下时诊断故障状态的方法。该方法可以包括确定热泵系统10的低效率的和/或无效的操作原因是否为充注不足状态(即，热泵系统10内的工作流体不足)、过充状态(即，热泵系统10内工作流体过多)、或热泵系统10内的流动限制(即，液体管线内的工作流体流限制或在室外热交换器20或室内热交换器16处的空气流限制)。
在步骤110处，回气温度传感器30、供气温度传感器32以及液体管线温度传感器34可以在它们各自位置处检测温度并将此数据传输至处理装置40。如上所述，检测和传输此数据可以是按需地、间歇地、平均每隔一定时间段、或实时地执行。在步骤120处，处理装置40可以确定回气温度减液体管线温度所得的值。当热泵系统10在加热模式下操作时，液体管线温度可以为由液体管线温度传感器34所检测的温度。
在步骤130处，处理装置40可以确定在步骤120处计算的值(供气温度减液体管线温度)是高于还是低于第一预定值。第一预定值可以对应于特定热泵系统和/或可以基于由外部空气温度传感器38所确定的当前外部空气温度。
如果处理装置40确定(在步骤130处)在步骤120处所确定的值低于第一预定值，则处理装置40可以在步骤140处计算液体管线温度与回气温度的差值。在步骤150处，处理装置40可以确定在步骤140所计算的值(液体管线温度减回气温度)是高于还是低于第二预定值。第二预定值可以对应于特定热泵系统和/或可以基于由外部空气温度传感器38确定的当前外部空气温度。如果在步骤150处处理装置40确定在步骤140处所计算的值低于第二预定值，则处理装置40可以在步骤160处给通知装置42发送指示出热泵系统10充注不足并且工作流体应当加入热泵系统10的通知。如果在步骤150处处理装置40确定在步骤140处所计算的值高于第二预定值，则处理装置40可以在步骤170处确定：系统充注是充分的和/或任何系统故障都与系统充注无关。
如果在步骤130处处理装置40确定在步骤120处所确定的值高于第一预定值，则处理装置40可以在步骤180处计算供气温度与回气温度的差值。在步骤190，处理装置40可以确定在步骤180处计算的值(供气温度减回气温度)是高于还是低于第三预定值。第三预定值可以对应于特定的热泵系统和/或可以基于由外部空气温度传感器38确定的当前外部空气温度。如果在步骤190处处理装置40确定在步骤180处所计算的值低于第三预定值，则处理装置40可以在步骤200处给通知装置42发送指示出在热泵系统10内存在工作流体流限制的通知。如果在步骤190处处理装置40确定在步骤180处所计算的值高于第三预定值，则处理装置40可以在步骤210处给通知装置42发送指示出热泵系统10被过充注并且应该减少热泵系统10中的工作流体的量的通知。
除了诊断热泵系统10的故障之外，处理装置40例如可以按需或以预定的时间间隔执行上述方法步骤以证实热泵系统10的充注。如果处理装置40确定热泵系统10被过充注、充注不足和/或存在一些其他故障状态，处理装置40可以给通知装置42发送适当的通知，如上所述。
技术人员也可以使用处理装置40和通知装置42来在热泵系统10初始安装到房屋或建筑物内期间执行热泵系统10的初始充注。即，实时供气温度测量、回气温度测量、液体管线温度测量和外部空气温度测量可以由处理装置40来处理，并且可以经由通知装置42为技术人员提供来自处理装置40的实时反馈，该实时反馈指示出热泵系统10何时已经达到最佳充注水平(即，技术人员何时应该停止对热泵系统10添加工作流体)。
例如，处理装置40可以监测(实时)液体管线温度与回气温度的差值。该值可以随着技术人员在初始系统充注期间添加工作流体而继续增大，直至达到最佳充注水平为止。一旦达到最佳充注水平，对热泵系统10添加更多工作流体会使液体管线温度与回气温度的差值减小。因此，处理装置40和通知装置42可以在液体管线温度与回气温度的差值开始减小时就通知技术人员。当技术人员收到此通知时，他或她可以停止对热泵系统10添加工作流体。
上述第一预定值、第二预定值和第三预定值可以被选择为对应于特定的热泵系统，并且可以通过例如实验或从查找表来确定。
