制冷电器和使噪声冲击最小化的方法 技术领域
本主题总体涉及诸如空调电器和冰箱电器的制冷电器，并且更具体地涉及用于使由这种电器产生的噪声的冲击最小化的特征和方法。
背景技术
通常，制冷电器(例如，冰箱电器、空调电器等)产生的噪声量随着时间的流逝而减少。技术的进步允许现代消费电器产生比几年前大多数消费电器更少的噪声。先进的阻尼材料也减少了现代电器发出的可听噪声量。然而，来自制冷电器(例如，在容纳制冷电器的房间内)的过多或不期望的噪声仍然是用户经常关注的问题。
如果制冷电器包括根据不同的速度和时间表运行的多个流体推动单元，诸如泵、压缩机或风扇，则可能加剧这些关注的问题。虽然这种电器由于它们可以对不同的条件(例如，环境温度、使用负荷等)做出响应并响应于这些条件改变其运行而可以比以前的电器更高效，但所产生的噪声甚至可能更易被感知。作为示例，对于用户来说，可能更显著的是风扇的速度在多个档位(例如，低档位和高档位)之间瞬间切换，然后将风扇维持在单个速度档位。作为另一个示例，与同时启动风扇和压缩机时相比，对于用户来说可能更显著的是突然分别启动风扇和压缩机，因为噪声的多次突然增加可能引起用户的注意。在任一示例中，由电器产生的噪声的明显变化和即时变化(即，可变噪声级)可以比单个持续噪声级更易被感知，即使持续噪声级在量级(例如，如以分贝dB为单位测量的)上大于可变噪声级。因此，可变噪声级将经常打扰用户并降低用户对给定电器的整体享受。
已经尝试通过使用相位与噪声的相位相反的声音(例如，抗噪声信号)来掩蔽或消除噪声。然而，这种系统通常增加电器的整体复杂性和成本。比如，需要有源声源(诸如扬声器)来传输这种声音。这些部件可能特别增加材料成本和组装复杂性。而且，可能难以在要被掩蔽的声音的音量或频率迅速变化的环境中实施主动声音掩蔽。
因此，提供一种被构造为解决上述问题中的一个或多个的消费电器将是有用的。特别地，提供一种具有用于使可检测冲击(例如，用户感知的听觉冲击)最小化的特征的制冷电器可以是有利的，该冲击由制冷电器中的一个或多个流体推动单元引 起

在本公开的另一个示例性方面中，提供了一种冰箱电器。该冰箱电器可以包括壳体、第一流体推动单元(FMU)、第二FMU以及控制器。壳体可以限定冷藏室。第一FMU可以安装到壳体，以产生制冷电器上的第一流体流动。第二FMU可以与第一FMU分离地安装到壳体，以产生制冷电器上的第二流体流动。控制器可以与第一FMU和第二FMU可操作地通信。控制器可以被配置为发起冷却运行。冷却操作可以包括：启动第一FMU，以产生第一流体流动；以第一预定斜升率在第一预定斜升时段内将第一FMU的速度档位逐渐提高到第一运行速度档位；在启动第一FMU之后启动第二FMU，以产生第二流体流动；以及以第二预定斜升率在第二预定斜升时段内将第二FMU的速度档位逐渐提高到第二运行速度档位。

现在转向附图，图1提供了制冷电器的立体图。具体地，图1提供了根据本公开的示例性实施方式的冰箱电器100。图2提供了冰箱电器100的前视图，其中冰箱门体128和冷冻门体130被示出为处于打开位置。
冰箱电器100包括箱体或壳体102，该箱体或壳体沿着竖向V在顶部104与底部106之间延伸，沿着侧向L在第一侧108与第二侧110之间延伸，并且沿着横向T在前侧112与后侧114之间延伸。竖向V、侧向L以及横向T中的每一个彼此互相垂直。
壳体102限定用于接收食品以便储存的冷藏室。特别地，壳体102限定设置在壳体102的顶部104处或与其相邻设置的新鲜食物室122和设置在壳体102的底部106处或与其相邻设置的冷冻室124。由此可见，冰箱电器100通常被称为下置式冰箱。然而，认识到，本公开的益处适用于其他类型和样式的制冷电器(例如，上置式冰箱电器、对开门式冰箱电器、整体式末端空调电器、整体式中央空调电器、分体式空调系统等)。因此，本文阐述的描述仅出于例示性目的，而无意于在任何方面 限于任何特定的制冷电器构造。
在所例示的实施方式中，冷冻室124通常沿着侧向L在左壁与右壁之间延伸，沿着竖向V在底壁与顶壁之间延伸，并且沿着横向T在室开口与后壁之间延伸。在可选实施方式中，冰箱电器100还包括中梁，该中梁设置在冷冻室124内，以将冷冻室124分为第一冷冻室和第二冷冻室。可选地，中梁通常可以沿着横向T在室开口与后壁之间延伸，并且沿着竖向V在底壁与顶壁之间延伸。这样，中梁通常可以是竖直定向的，并且将冷冻室124分成两个(例如，尺寸相等)的室180、182(图3)。
冰箱门体128可旋转地铰接到壳体102的边缘，以便选择性地接近新鲜食物室122。类似地，冷冻门体130可旋转地铰接到壳体102的边缘，以便选择性地接近冷冻室124。为了防止冷空气泄漏，冰箱门体128、冷冻门体130或壳体102可以在门体128、130与壳体102相遇的界面处限定一个或多个密封机构(例如，橡胶垫圈)。冰箱门体128和冷冻门体130在图1中被示出为处于关闭位置，并且在图2中被示出为处于打开位置。
冰箱电器100还包括用于分配液态水或冰的分配组件132。分配组件132包括分配器134，该分配器被设置在冰箱电器100的外部上或安装到该外部(例如，在冰箱门体128中的一个上)。分配器134包括用于获取冰和液态水的排放口136。被示出为拨片的致动机构138安装在排放口136下方，以便操作分配器134。在另选示例性实施方式中，可以使用任意合适的致动机构来操作分配器134。例如，分配器134可以包括传感器(例如，超声传感器)或按钮，而不是拨片。设置控制面板140，以便控制操作模式。例如，控制面板140包括多个用户输入(未标记)，诸如水分配按钮和冰分配按钮，这些用户输入用于选择期望的操作模式，诸如碎冰或非碎冰。
排放口136和致动机构138是分配器134的外部零件，并且安装在分配器凹部142中。分配器凹部142设置在预定高度处，该预定高度方便用户取冰或水，并且使得用户能够在不需要弯腰的情况下且在不需要打开冰箱门体128的情况下取冰。在示例性实施方式中，分配器凹部142设置在接近用户的胸部水平的水平处。根据示例性实施方式，分配组件132可以从制冰机152接收冰，该制冰机设置在冷藏室(例如，新鲜食物室122)的子室中。如将理解的，制冰机152可以包括一个或多个用于选择性地供应液态水以便冷冻的水阀。另外或另选地，可以在制冰机152内或在冰箱电器100内的别处设置一个或多个加热元件159(例如，以选择性地加热制冰机模具主体的部分或对冰箱电器100的各种部分除霜)。比如，冰箱电器100还可以包括 设置在新鲜食物室122或冷冻室124内的加热元件159。在这种实施方式中，加热元件159通常被构造为升高对应新鲜食物室122(例如，其蒸发器)或冷冻室124(例如，其蒸发器)的温度。另外或另选地，加热元件159可以被设置为帮助防止蒸发器198的不期望冻结或促进其解冻(例如，经由传导或通过加热穿过蒸发器198循环的空气)。通常，加热元件159可以包括一个或多个加热元件，诸如带状电阻加热器、加热线圈或任意其他合适的加热元件。
在一些实施方式中，冰箱电器100还包括控制器144。冰箱电器100的运行通常可以由控制器144来调节，该控制器可操作地耦合到控制面板140。在示例性实施方式中，控制面板140表示通用I/O(“GPIO”)装置或功能块。在其他示例性实施方式中，控制面板140包括输入部件，诸如包括旋转拨号盘、按钮、触摸板以及触摸屏的各种电气、机械或机电输入装置中的一个或多个。控制面板140可以经由一条或多条信号线或共享的通信总线与控制器144通信。控制面板140提供用于用户对冰箱电器100的运行的操纵的选择。响应于用户对控制面板140的操纵，控制器144运行冰箱电器100的各种部件。例如，如下面讨论的，控制器144与密封冷却系统190的各种部件可操作地耦合或通信(图3和图4)。控制器144还可以与各种传感器通信，诸如例如室温度传感器156或环境温度传感器158。控制器144可以从这些温度传感器156、158接收信号，这些信号对应于传感器各自位置内的大气或空气的温度。而且，控制器144可以基于从控制面板140、传感器156、158或冰箱电器100的另一个合适部分接收的信号来发起一个或多个运行(例如，冷却运行)。
控制器144包括存储器和一个或多个处理装置，诸如微处理器、CPU等，诸如通用或专用微处理器，该微处理器可操作为执行与冰箱电器100的运行关联的编程指令或微控制代码。存储器可以表示诸如DRAM的随机存取存储器或诸如ROM或FLASH的只读存储器。在一些实施方式中，处理器执行存储在存储器中的永久编程指令。对于某些实施方式，指令包括软件包，该软件包用于运行冰箱电器100，并且例如执行运行例程，该运行例程包括下面参照图6描述的示例方法600。存储器可以是与处理器分开的部件，或者可以机载地包括在处理器内。另选地，控制器144可以在不使用微处理器的情况下(例如，使用离散的模拟或数字逻辑电路的组合；诸如开关、放大器、积分器、比较器、触发器、与门等)构建为执行控制功能，而不是依靠软件。
在一些实施方式中，如本领域技术人员所知的，各种储存部件被安装在新鲜食物室122和冷冻室124内，以方便食品在其中的储存。特别地，储存部件包括安装 在新鲜食物室122或冷冻室124内的盒146、抽屉148以及层架150。盒146、抽屉148以及层架150用于接收食品(例如，饮料或固体食品)，并且可以帮助组织这些食品类别。作为示例，抽屉148可以接收新鲜食品(例如，蔬菜、水果或奶酪)，并且增加这种新鲜食品的使用寿命。
现在转向图3至图5，提供了冰箱电器100的多个示意图，以例示例如密封冷却系统190的各种部分。具体地，图3提供了前示意图，该前示意图例示了在冷藏室122、冷冻室124内或与其热连通的密封冷却系统190的部分。对于图3，注意的是，为了清楚起见，去除门体128、130(图1)。图4提供了后示意图，该后示意图例示了与冷藏室122、冷冻室124(图3)隔开的、冰箱电器100的后部(例如，机械室200)上或内的密封冷却系统190的部分。
密封冷却系统190通常被构造为执行蒸汽压缩循环，该蒸汽压缩循环用于冷却冰箱电器100内(例如，新鲜食物室122和冷冻室124内)的空气。设置一个或多个流体推动单元(FMU)(例如，压缩机、风扇、鼓风机、泵等)，以推动对应的流体(诸如制冷剂流体或空气)穿过密封冷却系统190(例如，如在压缩机的情况下)或穿过密封冷却系统190的一部分(例如，如在风扇的情况下)。
在某些实施方式中，一个或多个FMU设置有多个运行速度档位(例如，低速档位、中速档位以及高速档位)。各个运行速度档位可以是预定速度档位，该预定速度档位通常对应于流体流经或流过FMU的期望体积流量。FMU的低速档位可以对应于相对较慢的体积流量；FMU的中速档位可以对应于中等体积流量，该中等体积流量大于低速档位的体积流量；FMU的高速档位可以对应于相对较快的体积流量，该体积流量大于低速档位或中等档位的体积流量。由此，一个或多个FMU可以是变速FMU(例如，变速压缩机、变速风扇、变速鼓风机、变速泵等)。
在所例示的实施方式中，密封冷却系统190包括至少一个FMU(例如，第一FMU或压缩机192)、冷凝器194、膨胀装置196以及蒸发器198，这些部件串联连接并填充有制冷剂。在一些实施方式中，在密封冷却系统190的运行期间，气态制冷剂流入压缩机192(例如，设置为变速压缩机)中，该压缩机192运行以增大制冷剂的压力。制冷剂的该压缩升高其温度，该温度通过使气态制冷剂穿过冷凝器194来降低。在冷凝器194内，发生与周围空气的热交换，以便冷却制冷剂并使得制冷剂冷凝为液态。在可选实施方式中，至少一个FMU(例如，第二FMU或冷凝器风扇218)指向冷凝器194(例如，在机械室200内)，以选择性地帮助与冷凝器194和环境空气换热。例如，冰箱电器100可以包括冷凝器风扇218(例如，设置为变速风扇)，该冷 凝器风扇与机械室200流体连通，以便推动空气穿过冷凝器194。
膨胀装置196可以被设置为例如阀、毛细管或从冷凝器194接收液态制冷剂的其他限制装置。液态制冷剂从膨胀装置196进入蒸发器198。在离开膨胀装置196并进入蒸发器198时，液态制冷剂的压力下降并蒸发。由于制冷剂的压降和相变，蒸发器198相对于冰箱电器100的新鲜食物室122和冷冻室124是凉的。由此可见，产生冷却空气并且对冰箱电器100的新鲜食物室122和冷冻室124进行制冷。由此，蒸发器198是一种热交换器，该热交换器将热量从经过蒸发器198的空气传递到流过蒸发器198的制冷剂。
应当理解，所例示的密封冷却系统190仅仅是密封冷却系统190的示例性构造，该密封冷却系统可以包括附加的部件(例如，一个或多个附加的蒸发器、压缩机、膨胀装置或冷凝器)。作为示例，密封冷却系统190还可以包括储液器199。储液器199可以设置在蒸发器198的下游，并且可以被构造为在将来自制冷剂流的冷凝制冷剂传递到压缩机192之前收集它。
总体参照图3和图4，蒸发器198的一部分可以设置在冷冻室124内(例如，与冷冻室124的内胆的后壁相邻)。在另外或另选的实施方式中，蒸发器198的一部分设置在新鲜食物室122上或内(例如，与新鲜食物室122的内胆的后壁相邻)。密封冷却系统190的其他部件(例如，压缩机192和冷凝器194)可以位于冰箱电器100的机械室200内。
在所例示的实施方式中，蒸发器198包括第一蒸发器部分204、第二蒸发器部分206以及第三蒸发器部分208。第一蒸发器部分204、第二蒸发器部分206以及第三蒸发器部分208可以流体连通地(例如，串联或并联)连接，使得制冷剂在第二蒸发器部分206或第三蒸发器部分208之前首先穿过第一蒸发器部分204。在示例性实施方式中，第一蒸发器部分204通过固定导管支路连接到第二蒸发器部分206和第三蒸发器部分208。在诸如图5所例示的实施方式的另选实施方式中，第一蒸发器部分204通过多路阀210连接到第二蒸发器部分206、第三蒸发器部分208，该多路阀用于将制冷剂选择性地引导到第二蒸发器部分206和第三蒸发器部分208。如图例示，第一蒸发器部分204设置在第一冷冻室180内，第二蒸发器部分206设置在第二冷冻室182内，并且第三蒸发器部分208设置在新鲜食物室122内。然而，应当理解，根据另选实施方式，用于蒸发器198的任意其他合适的构造是可能的并且在本公开的范围内。
冰箱电器100还可以包括一个或多个FMU，诸如风扇，以帮助使空气循环穿过蒸 发器198和冷藏室122、冷冻室124中的一个或多个。作为示例，冰箱电器100可以包括至少一个FMU(例如，第三FMU或第一风扇212)，该FMU与第一蒸发器部分204流体连通，以便推动空气穿过第一蒸发器部分204。可选地，第一风扇212被设置为变速风扇。作为另外或另选示例，冰箱电器100可以包括至少一个FMU(例如，第四FMU或第二风扇214)，该FMU与第二蒸发器部分206流体连通，以便推动空气穿过第二蒸发器部分206。可选地，第二风扇214被设置为变速风扇。作为另一个另外或另选示例，冰箱电器100可以包括至少一个FMU(例如，第五FMU或第三风扇216)，该FMU与第三蒸发器部分208流体连通，以便推动空气穿过第三蒸发器部分208。可选地，第三风扇216被设置为变速风扇。
如所理解的，冰箱电器100内的一个或多个风扇(例如，风扇212、214、216、218)可以被设置为与对应的热交换器(例如，第一蒸发器部分204、第二蒸发器部分206、第三蒸发器部分208、冷凝器194等)流体连通的任意合适的风扇(例如，轴流风扇，径向鼓风机等)。作为示例，第一风扇212可以是轴流风扇，该轴流风扇设置在第一蒸发器部分204与第一冷冻室180之间，以选择性地循环空气并促进第一蒸发器部分与第一冷冻室之间的热交换。作为另一个示例，第二风扇214可以是轴流风扇，该轴流风扇设置在第二蒸发器部分206与第二冷冻室182之间，以选择性地循环空气并促进第二蒸发器部分与第二冷冻室之间的热交换。作为又一个示例，第三风扇216可以是轴流风扇，该轴流风扇设置在第三蒸发器部分208与新鲜食物室122之间，以选择性地循环空气并促进第三蒸发器部分与新鲜食物室之间的热交换。作为又一个示例，冷凝器风扇218可以是设置在机械室200内以使空气在其中循环的轴流风扇。
虽然FMU(例如，192、212、214、216以及218)通常可以根据冰箱电器100的冷却需求来启动和控制，但如下面将描述的，FMU的启动和运行(例如，速度档位)可以错开或按顺序排列。
现在转向图6，提供了根据本公开的示例性实施方式的方法600的流程图。通常，方法600提供了一种运行制冷电器的方法，该制冷电器诸如如上所述的包括多个FMU的冰箱电器100(图1)。方法600可以比如由控制器114(图1)执行。例如，如所讨论的，控制器144可以可操作地耦合到一个或多个FMU(例如，192、212、214、216以及218)、室传感器156、环境传感器158或用户控制面板140。在运行期间，控制器144可以向FMU(例如，192、212、214、216以及218)、室传感器156、环境传感器158或用户控制面板140发送信号或从其接收信号。控制器144通常还可 以可操作地耦合到电器100的其他合适部件，以便于冰箱电器100的运行。
在610处，方法600包括以下步骤：启动第一FMU，以产生第一流体流动。通常，第一FMU可以从静止开始运行，使得第一流体流动在大体静止(例如，流体流速为零)之后开始。第一FMU可以被设置为例如压缩机、风扇、鼓风机、泵或用于推动流体(例如，制冷剂、水、空气等)穿过相对静态的主体的任意其他以有源方式提供动力的部件。作为示例，如果第一FMU被设置为压缩机，则610可以包括启动压缩机，使得制冷剂流过密封冷却系统。作为另一个示例，如果第一FMU被设置为风扇，则610可以包括使风扇从静止旋转，使得穿过风扇外壳并且在对应的室(例如，如上所述)内产生主动气流。在一些这种实施方式中，如上所述，风扇是冷凝器风扇。
在某些实施方式中，第一FMU被设置为多个FMU中声音最大的一个。换言之，第一FMU可以是在其对应的运行速度档位下产生最高量级(例如，如用户将在使用制冷电器期间所假定的，如从制冷电器前面的位置以分贝为单位测量的)的噪声的FMU。
在一些实施方式中，610通过接收冷却信号来发起或激起。通常，冷却信号通常可以指示一个或多个FMU的启动将是期望的(例如，以冷却或以其他方式降低制冷电器的一部分内的温度)。如通常理解的，可以根据一个或多个方法或顺序来确定冷却是必要的。在可选实施方式中，冷却信号指示对应温度传感器在制冷电器的一部分处检测到的温度已经升高到设定温度极限以上。比如，冷却信号可以从一个或多个温度传感器(诸如上述温度传感器)接收。在另外或另选的实施方式中，冷却信号指示已经发起冰分配操作。比如，冷却信号可以响应于用户致动致动机构或拨片而从分配器接收。有利地，启动第一FMU可以掩蔽由加热元件、从制冷电器或在制冷电器内落下的冰的移动、引导水以重新注满制冰机的水阀的启动等产生的噪声。
在620处，方法600包括以下步骤：以第一预定斜升率在第一预定斜升时段内将第一FMU的速度档位逐渐提高到第一运行速度档位。由此，620通常在610后发生，并且提供大于零的运行速度档位。在一些实施方式中，第一运行速度档位是预定速度档位，该预定速度档位通常对应于流体流经或流过第一FMU的期望体积流量。第一预定斜升率是逐渐提高第一FMU的速度档位(例如，从零或静止)的提高率。逐渐提高可以持续几秒钟(例如，3到5秒)，并且响应于第一FMU达到第一运行速度档位而停止。一旦达到第一运行速度档位，则第一FMU可以继续以第一运行速度运行(例如，直到对于第一FMU期望新的运行速度档位、冷却运行结束、或者不再期 望启动第一FMU为止)。有利地，与从静止到第一运行速度档位的即时无限制的提高相比，速度的逐渐提高可能在听觉上更不可感知(例如，对于用户而言)。
在630处，方法600包括以下步骤：在启动第一FMU之后启动第二FMU(例如，以产生第二流体流动)。换言之，630仅在610之后发生或开始。通常，第二FMU可以从静止开始运行，使得第二流体流动在大体静止(例如，流体流速为零)之后开始。第二FMU可以被设置为例如压缩机、风扇、鼓风机、泵或用于推动流体(例如，制冷剂、水、空气等)穿过相对静态的主体的任意其他以有源方式提供动力的部件。作为示例，如果第二FMU被设置为压缩机，则630可以包括启动压缩机，使得制冷剂流过密封冷却系统。作为另一个示例，如果第二FMU被设置为风扇，则630可以包括使风扇从静止旋转，使得穿过风扇并且在对应的室(例如，如上所述)内产生主动气流。有利地，由第二FMU产生的噪声的至少一部分可以被由第一FMU产生的噪声掩蔽。
在一些实施方式中，第二FMU的启动(即630)被延迟设定的顺序时段(例如，以秒为单位定义)。换言之，仅在设定的顺序时段到期时才可以允许630开始。在到期之前，可以将第二FMU保持为不活动或者以其他方式阻止其启动。可选地，设定的顺序时段可以在第一FMU达到设定的运行速度档位之前到期。由此，630可以在620的至少一部分期间发生。
在另选实施方式中，第二FMU的启动(即630)在第一FMU达到第一运行速度档位之后发起。换言之，630可以在620之后发生。在一些这种实施方式中，630响应于620(例如，紧随其后)发生。在其他实施方式中，630被进一步延迟，直到设定的时间段在第一FMU达到第一运行速度档位之后到期为止。
在640处，方法包括以下步骤：以第二预定斜升率在第二预定斜升时段内将第二FMU的速度档位逐渐提高到第二运行速度档位。由此，640通常在630后发生，并且提供大于零的运行速度档位。在一些实施方式中，第二运行速度档位是预定速度档位，该预定速度档位通常对应于流体流经或流过第二FMU(例如，与第一流体流动或第一运行速度档位分开)的期望体积流量。第二预定斜升率是逐渐提高第二FMU的速度档位(例如，从零或静止)的提高率。逐渐提高可以延续几秒钟(例如，3到5秒)，并且响应于第二FMU达到第二运行速度档位而停止。一旦达到第二运行速度档位，则第二FMU可以继续以第二运行速度运行(例如，直到对于第二FMU期望新的运行速度档位、冷却运行结束、或者不再期望启动第二FMU为止)。有利地，与从静止到第二运行速度档位的即时无限制的提高相比，速度的逐渐提高可能在听觉上 更不可感知(例如，对于用户而言)。
如上所述，第二FMU的启动可以在第一FMU达到第一运行速度档位之前发生。在一些这种实施方式中，640在第一预定斜升时段期间发起。在另选实施方式中，640仅在第一FMU已经达到第一运行速度档位之后才发起。
在某些实施方式中，方法600不仅提供第一FMU和第二FMU的速度档位的逐渐提高，还提供逐渐降低。逐渐降低可以在达到第一运行速度档位和第二运行速度档位之后(例如，当第一FMU和第二FMU这两者分别以第一运行速度档位和第二运行速度档位活动地运行时)开始。在一些这种实施方式中，方法600包括以下步骤：以第一预定降低率从第一运行速度档位逐渐地(例如，在第一预定降低时段内，诸如可以以秒为单位测量的)降低第一FMU的速度档位。逐渐降低可以一直持续到例如第一FMU达到零的速度档位或者以其他方式不活动为止。类似地，方法600可以包括以下步骤：以第二预定降低率从第二运行速度档位逐渐地(例如，在第二预定降低时段内，诸如可以以秒为单位测量的)降低第二FMU的速度档位。逐渐降低可以一直持续到例如第二FMU达到零的速度档位或者以其他方式不活动为止。
可选地，第二FMU的逐渐降低可以与第一FMU的逐渐降低重叠。比如，随着第一FMU的速度档位降低，第二FMU的速度档位也可以降低。
另外或另选地，第二FMU的逐渐降低可以仅在第一FMU的逐渐降低已经开始之后开始。
而且另外或另选地，第一FMU的逐渐降低可以被配置为仅在第二FMU的逐渐降低结束之后才结束。由此，第一FMU可以从第二FMU活动之前的时间到第二FMU不活动之后的稍后时间保持活动。在一些这种实施方式中，第一FMU的逐渐降低可以被配置为在预定时间段内发生，该预定时间段对应于密封冷却系统内的压力均衡(例如，蒸发器与冷凝器之间的均衡)。例如，第一FMU可以是冷凝器风扇，而第二FMU可以是压缩机。由此，在压缩机达到不活动状态和对应密封冷却系统内的制冷剂压力之后，冷凝器风扇可以保持活动。
有利地，由第一FMU产生的噪声可以掩蔽由第二FMU或密封冷却系统产生的噪声。
在某些实施方式中，如上所述，第一FMU被设置为变速FMU。由此，第一FMU可以具有多个第一运行速度档位。作为示例，第一FMU可以具有第一低速档位、第一中速档位以及第一高速档位。在一些这种实施方式中，方法600还包括以下步骤：再次提高第一FMU的速度档位(即，在620之后)。例如，第一FMU的速度档位可以 从第一低速档位提高到第一中速档位或第一高速档位。再次提高第一FMU的速度档位也可以逐渐发生(例如，分别地，以等于或不同于第一预定斜升率的预定斜升率在等于或不同于第一预定时间段的预定时间段内)。类似地，如果方法600提供第一FMU的逐渐降低，则方法600可以进一步提供降低第一FMU的速度档位(例如，从第一高速档位降低到第一中速档位或第一低速档位)。
在另外或另选实施方式中，如上所述，第二FMU被设置为变速FMU。由此，第二FMU可以具有多个第二运行速度档位。作为示例，第二FMU可以具有第二低速档位、第二中速档位以及第二高速档位。在一些这种实施方式中，方法600还包括以下步骤：再次提高第二FMU的速度档位(即，在640之后)。例如，第二FMU的速度档位可以从第二低速档位提高到第二中速档位或第二高速档位。再次提高第二FMU的速度档位也可以逐渐发生(例如，分别地，以等于或不同于第二预定斜升率的预定斜升率在等于或不同于第二预定时间段的预定时间段内)。类似地，如果方法600提供第二FMU的逐渐降低，则方法600可以进一步提供降低第二FMU的速度档位(例如，从第二高速档位降低到第二中速档位或第二低速档位)。
注意，虽然图6处仅列出了两个FMU，但方法600可以包括另外FMU的类似启动。比如，可以设置第三FMU，并且方法600可以包括以下步骤：在启动第二FMU之后启动第三FMU，以产生第三流体流动；以及以第三预定斜升率在第三预定时间段内将第三FMU的速度档位逐渐提高到第三运行速度档位。在另外的示例中，如鉴于以上描述将理解的，可以类似地顺序启动另外的FMU，以逐渐提高速度。
在另外的实施方式中，作为方法600的一部分，可选择性地启动以大体恒定的频率产生一个或多个不期望的噪声的一个或多个有声电子元件(例如，如上所述的制冰机、水阀或加热元件)。比如，方法600可以包括以下步骤：在610之后的设定延迟时段内启动有声电子元件。在一些这种实施方式中，有声电子元件在620期间或在第一FMU继续以第一运行速度档位运行的同时启动。比如，可以在第一FMU(例如，冷凝器风扇)启动的同时(例如，在620期间或之后)启动加热元件，以便在蒸发器处进行除霜操作。由此，有声电子元件的启动可以被调整为与第一FMU的运行重叠，并且由有声电子元件产生的噪声的至少一部分可以有利地被由第一FMU产生的噪声掩蔽。
现在转向图7，该图例示了随着时间(如以秒为单位测量的)流逝由示例性制冷电器(例如，冰箱电器100-图1)产生的噪声(如以分贝为单位测量的)。如上所述，示例性制冷电器可以包括多个FMU，诸如第一FMU、第二FMU、第三FMU、第四FMU 以及第五FMU。而且，如所理解的，各个FMU在不运行时将产生0噪声级，但通常将随着对应速度档位提高而增加噪声产生。
通常，各个FMU可以单独启动。在所例示的图中，第一FMU(例如，被设置为压缩机或另选地设置为冷凝器风扇)被启动并以第一预定斜升率逐渐提高速度(即，速度档位逐渐提高)，直到达到运行速度档位为止。随着第一FMU的速度提高，第二FMU(例如，被设置为冷凝器风扇或另选地设置为压缩机)被启动并以第二预定斜升率逐渐提高速度，直到达到第二运行速度档位为止。在第二FMU达到第二运行速度档位之后，第三FMU(例如，被设置为第一蒸发器风扇)被启动并以第三预定斜升率逐渐提高速度，直到达到第三运行速度档位为止。随着第三FMU的速度提高，第四FMU(例如，被设置为第二蒸发器风扇)被启动并以第四预定斜升率逐渐提高速度，直到达到第四运行速度档位为止。随着第四FMU的速度提高，第五FMU(例如，被设置为第三蒸发器风扇)被启动并以第五预定斜升率逐渐提高速度，直到达到第五运行速度档位为止。
注意，虽然图7例示了被启动并提高速度的特定顺序的FMU，但根据本公开，另选实施方式可以在多个FMU之间提供任意合适的顺序或速度提高。
本书面描述使用示例对本发明进行了公开(其中包括最佳模式)，并且还使本领域技术人员能够实施本发明(其中包括制造和使用任何装置或系统并且执行所包含的任何方法)。本发明的可专利范围通过权利要求进行限定，并且可以包括本领域技术人员能够想到的其它的示例。如果这种其它的示例包括与权利要求的字面语言没有区别的结构元件，或者如果这种其它的示例包括与权利要求的字面语言没有实质区别的等同结构元件，则期望这种其它的示例落入权利要求的范围中。
