在本申请的描述中，需要说明的是，除非另有明确的规定和限定，术语“安装”、“相连”、“连接”应做广义理解，例如，可以是固定连接，也可以是可拆卸连接，或一体地连接；可以是机械连接，也可以是电连接；可以是直接相连，也可以通过中间媒介间接相连，可以是两个元件内部的连通。对于本领域的普通技术人员而言，可以具体情况理解上述术语在本申请中的具体含义。
本申请中空调器通过使用压缩机200、冷凝器、膨胀阀和蒸发器来执行空调器的制冷循环。制冷循环包括一系列过程，涉及压缩、冷凝、膨胀和蒸发，并向已被调节和热交换的空气供应制冷剂。
压缩机200压缩处于高温高压状态的制冷剂气体并排出压缩后的制冷剂气体。所排出的制冷剂气体流入冷凝器。冷凝器将压缩后的制冷剂冷凝成液相，并且热量通过冷凝过程释放到周围环境。
膨胀阀使在冷凝器中冷凝的高温高压状态的液相制冷剂膨胀为低压的液相制冷剂。蒸发器蒸发在膨胀阀中膨胀的制冷剂，并使处于低温低压状态的制冷剂气体返回到压缩机200。蒸发器可以通过利用制冷剂的蒸发的潜热与待冷却的材料进行热交换来实现制冷效果。在整个循环中，空调器可以调节室内空间的温度。
空调器的室外单元是指制冷循环的包括压缩机200和室外热交换器的部分，空调器的室内单元包括室内热交换器，并且膨胀阀可以提供在室内单元或室外单元中。
室内热交换器和室外热交换器用作冷凝器或蒸发器。当室内热交换器用作冷凝器时，空调器用作制热模式的加热器，当室内热交换器用作蒸发器时，空调器用作制冷模式的冷却器。
如图1，根据本申请一些实施例中的空调器，包括安装在室外空间中的室外单元。室外单元，通过管连接到安装在室内空间中的室内单元。室外单元中可设有压缩机200、室外热交换器、室外风扇、膨胀器和制冷循环的类似部件，室内单元中也可设有室内热交换器和室内风扇。
根据本申请的一些实施例中，室内单元中的室内风扇位于壳体100内部的大致中央部分。该室内风扇是在室内机的长度方向(左右方向)上呈细长的大致圆筒形状的交叉流动风扇。通过对室内风扇进行旋转驱动，室内空气从吸入口被吸入而通过空气过滤器之后通过室内热交换器而生成的调节空气从吹出口被吹出至室内。室内风扇根据室内风扇马达的转速进行旋转，转速越大，则从吹出口吹出的调节空气的风量越多；
在风速调整的模式中，存在自动设定和手动设定这两种模式。在自动设定模式中，控制器依照存储在存储器中的程序自动地设定风量或风量。在手动设定模式中，用户能够使用遥控器的风量或风速设定开关设定多个不同等级档位的风速或风量。这里，从风速较小的一方起依次称为第一风速、第二风速、第三风速、第四风速、以及第五风速。
如图1或图3，根据本申请一些实施例中的室外空调器，室外单元中设置的压缩机200，压缩机200的频率范围在30Hz-130Hz，且压缩机200的频率可根据空调器的运行模式，室内外温度及风速档位等级，调整压缩机200的频率，以适应空调器当前的运行状态，保证空调器的节能性能。
压缩机200可设置于室外单元的壳体100中，且压缩机200上连接有管路500，且压缩机200的吸气口和出气口上连接的管，管通过将膨胀阀、室外热交换器、室内热交换器和气液分离器连接形成空调器的制冷循环回路。
如图1，根据本申请的一些实施例中，如图1，空调器包括壳体100，壳体100中安装有构成制冷循环的多个部件。壳体100包括限定底部构造的前板110、限定后部构造的后板、限定底部构造的底板130、设置在底表面的两侧的侧板140、以及限定顶部外观的顶板120。
底板130。设置有连接架，连接架用于将整个壳体100连接到室外空间的壁上，或用于将整个壳体100固定到放置壳体100的面上。
连接架连接到底板130，连接架中可限定联接到壁的安装孔。例如，安装板可以联接到壁上，且壳体100可设置为安装在连接架上。
壳体100可以是在分离式空调的情况下设置室外空间中的室外单元壳体100，也可以是一体式空调的情况下的空调的自身壳体100。而且，在广义上，连接架可被理解为壳体100的一个部件。
如图2和图3，根据本申请的一些实施例中，壳体100上贴附有减振垫400，减振垫400为长度优选为300mm，宽度优选为150mm，厚度优选为2mm的油泥，重量为200g。
减振垫400用于阻断管路500的振动向壳体100的传递，有效防止壳体100发生振动产生的噪音。
减振垫400设置于壳体100的内壁上，且相对于管路500设置，且减振垫400设置于壳体100的侧板140上，且相邻于管路500设置。
如图3，根据本申请的一些实施例中，由于连接到压缩机200上的管路500具有一定的共振频率，且该共振频率可能会和压缩机200的工作频率一致而引起管路500振动，所以在压缩机200的管路500上设置有第一减振锤310和第二减振锤320。
第一减振锤310和第二减振锤320用于将管路500的固有共振频率改变为第一频率，以避开压缩机200在高频运行过程中运行的稳定频率，所以当压缩机200在高频运行时不会引起管路500的振动。
第一减振锤310和第二减振锤320设置于管路500上。
当空调器在制热模式下，压缩机200需要稳定在95Hz的高频范围内运行，而压缩机200第一减振锤310的质量在300g-400g之间，第二减振锤320的质量在150g-200g之间，且当第一减振锤310的质量为360g，第二减振锤320的质量为175g时，第一减振锤310和第二减振锤320将管路500的共振频率由95Hz(固有共振频率)改变为90Hz(第一频率)，所以压缩机200在95Hz范围内运行时不会引起管路500振动。
如图4-7，根据本申请的一些实施例中，第二减振锤320包括下壳体3310、上盖体3220和包裹层3400，且下壳体3310内形成有可填充减振材料的空腔3110，包裹层3400形成有用于套设管路500的卡套结构320。
通过上盖体3220和下壳体3310的配合连接，可在下壳体3310的空腔3110内可替换、增加或减少地放置有减振材料，以将管路500原有的共振频率改变为在一定的范围内的任一值，可根据需求改变管路500的共振频率；另外，第二减振锤320可移动的设置于吸气管510上，可以相对于吸气管510上下移动，压缩机200在运行过程中，吸气管510路500晃动，下减振锤跟着管路500晃动，可以有效的吸收或耗散吸气管510上的振动能量；包裹层3400的卡套结构320的直径大于管路500的直径，以实现将第二减振锤320可移动地连接于管路500上，具体的，卡套结构320的直径比吸气管510路500的直径大5mm-10mm，优选为7mm。
第一减振锤310设置于压缩机200的吸气管510上；第二减振锤320可移动地设置于压缩机200的吸气管510上，具体的，下壳体3310设置于吸气管510上，上盖体3220盖设于下壳体3310上；包裹层3400包裹于下壳体3310和上盖体3220，且套设在管路500上。
另外，下壳体3310和上盖体3220的材质为金属、塑料或陶瓷等，能够保证下壳体3310和上盖体3220的耐高温和刚度性能，在90-120℃范围内不会发生软化变形现象；若下壳体3310和上盖体3220的材质为钣金，则下壳体3310和上盖体3220的厚度为0.4-1mm，最优为0.6mm；若下壳体3310和上盖体3220的材质为塑料，则下壳体3310和上盖体3220的厚度为0.8-1.5mm，最优为1.2mm；包裹层3400的材质为橡胶或硅胶等，也可以保证包裹层3400的耐高温性能，在80-110℃范围内不会发生软化变形现象，此外，包裹层3400不会对配管产生腐蚀；减振材料可选择为金属颗粒、液体等材料，以使得在减振锤晃动过程中，减振材料在下壳体3310的腔体内部无规则晃动，进而耗散振动能量。减振材料填充到下壳体3310的腔体填充度(减振材料体积与腔体容积之比)为60％-100％，最优为95％。
根据本申请的一些实施例中，空调器还设置有控制器，控制器具有内置于室外单元内的室外控制装置和内置于室内单元内的室内控制装置。这些室外控制装置和室内控制装置构成为相互由信号线连接，能够相互发送/接收信号。
室外单元的室外控制装置控制压缩机200、膨胀阀、及室外风扇等。因此，室外单元具备:用于测定室外空气的温度的室外温度传感器；用于测定在室外热交换器的特定的场所流动的制冷剂的温度的室外热交换器温度传感器；用于检测从压缩机200排出的制冷剂的温度的排出管温度传感器；以 及用于检测被压缩机200吸入的气体制冷剂的温度的吸入管温度传感器。
并且，室外控制装置与室外温度传感器至吸入管温度传感器连接，以接收与室外温度传感器至吸入管温度传感器测定的温度相关的信号。该室外控制装置构成为例如包含CPU(未图示)和存储器、能够依照存储在存储器中的程序等进行室外单元的控制的结构。
室内单元的室内控制装置控制室内风扇等。因此，室内单元具备:用于实时获取室内空间的温度的室内温度传感器；和用于测定在室内热交换器的特定的场所流动的制冷剂的温度的室内热交换器温度传感器。并且，室内控制装置与室内温度传感器和室内热交换器温度传感器连接，以接收与室温变换器和室内热交换器温度变换器测定的温度相关的信号。该室内制御装置构成为例如包含CPU和存储器、能够依照存储在存储器中的程序等进行室内单元的控制的结构。
控制器电连接于压缩机200和室内温度传感器，如图9。
参照图8和图10，根据本申请的空调器的控制方法，其应用于如上的空调器中，控制方法包括；
S101，判断空调器当前的运行模式及风速档位等级。
S102，若空调器为制热模式且风速档位等级在预设等级范围内，使压缩机升频并跳过预定频率范围至第一预设频率运行。
其中，第一频率在预定频率范围内，第一预设频率高于预定频率范围。
当空调器的运行模式为制热模式时，且风速档位等级在预定档位范围内时，压缩机200需要升高到95Hz(第一预设频率)运行，且升频的过程中必然经过第一频率，所以当空调器为制热模式且风速档位等级在预设等级范围内，使得压缩机200升高频率并越过、修正或避开预定频率范围至第一预设频率运行，能够保证空调器在制热模式下将室内温度达到预定温度范围；同时，由于压缩机200在升频的过程中跳过了第一频率所在的预定频率范围，所以使得压缩机200在升频的过程中不会与管路500的第一频率一致而引起管路500的振动，直接杜绝了管路500噪音的产生。
另外，预定频率范围为88Hz-90Hz，经研发人员试验得出，在设置有第一减振锤和第二减振锤的情况下，压缩机200升频的过程中运行到该预定频率范围时在空调器的不同方向均会产生达到40dB-60dB的噪音，所以使压缩机200的升频过程中跳过该预定频率范围，能够有效保证空调器的静音运行， 提升用户体验。
为了保证空调器的正常工作，根据本申请的一些实施例中，控制方法还包括：
若空调器为制冷模式，或风速档位等级未在预设等级范围内，使压缩机以额定频率运行；
其中，额定频率低于预定频率范围。
当空调器的运行模式为制冷模式，或风速档位等级不在预定档位范围内时，压缩机200不需要升高第一预设频率进行运行，所以第二预设频率不会高于第一预设频率，且不高于预定频率范围，进而压缩机的运行频率也不会遇见第一频率而引起空调器中管路500的振动，所以使得压缩机200升高频率至第二预设频率，即可保证空调器在制冷模式下将室内温度保持在预定温度范围内。
为了保证空调器的运行能够使得室内空间的温度达到预设温度，保证用户体验，本申请的一些实施例中，方法还包括：
在压缩机以第一预设频率运行后；
若室内温度和预设温度之差小于预定值时，使压缩机由第一预设频率降频并跳过预定频率范围至稳定频率运行；
若室内温度和预设温度之差不小于预定值时，保持压缩机以第一预设频率运行；
其中，稳定频率低于预定频率范围。
当压缩机200升频至第一预设频率后，室内空间中的空气温度会在空调器的作用下升高至预设温度范围内，此时，如果压缩机200继续保持需求频率运行，会使得温度继续升高，且浪费了大量的电能；所以当室内空间中的空气温度会在空调器的作用下升高至预设温度范围内，会控制压缩机200降频至稳定频率下运行，且保持空调器的当前的运行模式不变，在降频的同时会跳过预设频率范围，避免在降频过程中引起管路的振动；当室内空间中的空气温度未到达预设温度范围内时，会继续保持压缩机200在第一预设频率下运行，且保持空调器的当前的运行模式不变。
根据本申请的控制方法，其可以依靠控制器及空调器的其他硬件设备实现，在此不多做限定。
根据本申请的第一构思，由于增设了第一减振锤和第二减振锤，将第一 减振锤设置于与压缩机连接的吸气管上，将第二减振锤设置于与压缩机连接的吸气管上，进而改变了吸气管和吸气管的共振频率，将管路的共振频率改变为第一频率，所以使得管路的共振频率和压缩机的运行频率不一致，避免压缩机引起管路振动产生噪音的情况出现。
根据本申请的第二构思，由于增设了减振垫，将减振垫设置于壳体的侧板的内壁上，且减振垫相对于管路设置，且减振垫相邻于管路设置，即，减振垫设置于管路和壳体的侧板之间，所以可以阻断振动由管路向壳体的传递，切断了振动的传递路径，有效降低了壳体噪音的产生。
根据本申请的第三构思，由于改进了减振锤的结构，将减振锤设置为可打开并更换、增减填充物的结构，当管路的共振频率由于环境因素发生改变时，所以可通过改变减振锤内的填充物将管路的共振频率稳定在第一频率，配合空调器的控制方法，有效的避免了壳体和管路振动或噪音的产生。
根据本申请的第四构思，由于改进了空调器的控制方法，控制方法包括：判断所述空调器当前的运行模式及风速档位等级；若所述空调器为制热模式且风速档位等级在预设等级范围内，使所述压缩机升频并跳过预定频率范围至第一预设频率运行，所以以使得压缩机的运行频率避开预定频率范围；其中，所述第一频率在所述预定频率范围内，所述第一预设频率高于所述预定频率范围，可以避免压缩机引起管路共振而产生噪音的问题。
具体地，本申请的目的之一就在于提供一种减震锤，减震锤设于配管上，用于减小配管的振动，提高空调器的运行可靠性。
参照图11，减震锤包括壳体组件3100和阻尼减振材料(未标示)，壳体组件3100的内部形成有封闭的空腔3110，空腔3110内填充阻尼减振材料。
通过阻尼减振材料对配管的振动能量进行耗散，起到耗能减振的作用，从而减小空调器的工作噪音，提高空调器的运行可靠性。
本申请一些实施例中，阻尼减振材料的形态为固体形态或液体形态或气体形态。固体形态包括润滑脂、石英砂、金属颗粒、陶瓷颗粒、橡胶颗粒等,采用颗粒物时颗粒的直径在26目-5mm之间，最优为1-3mm；液体形态包括油、水等；气体形态包括空气、压缩空气等。减震锤在随配管振动的过程中，阻尼减振材料在空腔内无规则晃动，进而耗散振动能量。
阻尼减振材料填充空腔的60-100％，最优为95％，以达到最优减振效果。
本申请一些实施例中，参照图12，壳体组件3100上设有卡槽3200，卡槽3200形成一侧具有开口3210的通孔结构，卡槽3200与配管可拆卸连接，实现减震锤与配管之间的可拆卸连接，便于减震锤的拆装。
卡槽3200紧靠空腔3110、且沿空腔3110的长度方向延伸，围成空腔3110的侧壁和围成卡槽3200的侧壁中，重叠的部分呈与配管适配的弧型壁3120。弧型壁3120包裹在配管的外周，增大与配管的接触面积，有助于提高减振耗能效果。
本申请一些实施例中，参照图12至图14，壳体组件3100包括内壳体3300和包裹层3400，包裹层3400包覆在内壳体3300的外部，内壳体3300的内部形成空腔3110，包裹层3400上设置卡槽3200。
内壳体3300的材质为金属或塑料或陶瓷等，内壳体3300需要具有耐高温性能，在90-120℃范围内不会发生软化变形现象。
若内壳体3300的材质为钣金，则内壳体3300的厚度为0.4-1mm，最优为0.6mm。若内壳体3300的材质为塑料，则内壳体3300的厚度为0.8-1.5mm，最优为1.2mm。
包裹层3400和卡槽3200的材质为橡胶或硅胶等，包裹层3400和卡槽3200也需要具有耐高温性能，在80-110℃范围内不会发生软化变形现象。此外，包裹层3400和卡槽3200不会对配管产生腐蚀。
内壳体3300包括下壳体3310和上盖体3220，以便于阻尼减振材料的填充及密封。
包裹层3400与卡槽3200一体注塑成型，便于加工。
本申请一些实施例中减震锤的加工过程为：
内壳体成型：若内壳体3300采用塑料，则通过注塑成型下壳体3310和上盖体3220；若内壳体3300采用钣金，则通过钣金冲压成型下壳体3310和上盖体3220；
阻尼减振材料填充：将阻尼减振材料填充到下壳体3310内；
密封：将下壳体3310和上盖体3220密封，将阻尼减振材料密封在空腔3110中；
包裹层成型：将得到的填充有阻尼减振材料的内壳体3300在特定模具中定位，然后在其外侧注塑成型包裹层3400和卡槽3200。
实施例一中通过独立的内壳体3300对阻尼减振材料进行盛装和密封， 便于加工和阻尼减振材料的密封。
本申请一些实施例中，参照图15和图16，壳体组件3100包括下壳体3510和上盖体3520，下壳体3510和上盖体3520扣合密封形成空腔3110，下壳体3510上设有卡槽3200。
下壳体3510、上盖体3520、以及卡槽3200的材质为橡胶或硅胶，下壳体3510与卡槽3200一体注塑成型。
本申请一些实施例中减震锤的加工过程为：
壳体组件成型：壳体组件3100采用橡胶或硅胶，通过注塑成型下壳体3510与卡槽3200的整体结构，注塑成型上盖体3520；
阻尼减振材料填充：将阻尼减振材料填充到下壳体3510内；
密封：将下壳体3510和上盖体3520密封，将阻尼减振材料密封在空腔3110中。
本申请一些实施例中壳体组件3100自身同时实现阻尼减振材料的盛装与密封、与配管的连接等功能，简化加工步骤。
在本说明书的描述中，具体特征、结构、材料或者特点可以在任何的一个或多个实施例或示例中以合适的方式结合。
以上，仅为本申请的具体实施方式，但本申请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申请揭露的技术范围内，可轻易想到的变化或替换，都应涵盖在本申请的保护范围之内。因此，本申请的保护范围应以所述权利要求的保护范围为准。
