下面参考附图描述根据本申请实施例的空调***100。
如图1所示，根据本申请第一方面实施例的空调***100，包括：压缩机1、换向组件2、室外换热组件、室内换热器4、节流装置5和冷媒支路6。
具体地，压缩机1具有吸气口12和排气口11。可选地，压缩机1可以为立式压缩机1，如图1所示。在本申请下面的描述中，以压缩机1为立式压缩机1为例进行说明。当然，本领域内的技术人员可以理解，压缩机1还可以为卧式压缩机1(图未示出)。这里，需要说明的是，“立式压缩机1”可以理解为压缩机1的压缩机1构的气缸的中心轴线垂直于压缩机1的安装面的压缩机1。相应地，“卧式压缩机1”可以理解为气缸的中心轴线大致平行于压缩机1的安装面的压缩机1。
如图1所示，压缩机1包括吸气口12和排气口11，其中，排气口11可以形成在压缩机1的顶部。吸气口12可以形成在压缩机1的侧壁上。进一步地，压缩机1还可以包括气液分离器，气液分离器与吸气口12相连，以防止压缩机1出现液击现象，由此，可以提高压缩机1的可靠性。
换向组件2包括第一接口21、第二接口22、第三接口23和第四接口24。可选地，换向组件2为四通阀。其中，第一接口21可以与排气口11相连，第三接口23可以与吸气口12相连。室外换热组件包括室外换热器3和底盘8，室外换热器3设在底盘8上，室外换热器3的一端(例如图1中室外换热器3的左端)与第二接口22相连，室内换热器4连接在第四接口24和室外换热器3的另一端(例如图1中室外换热器3的右端)之间。节流装置5设置在室外换热器3与室内换热器4之间。可选地，节流装置5可以为毛细管、电子膨胀阀等。
其中，第一接口21可以与第二接口22和第四接口24中的其中一个换向连通，第三接口23可以与第二接口22和第四接口24中的另一个换向导通。例如，当第一接口21与第二接口22连通时，第三接口23与第四接口24连通；当第一接口21与第四接口24连通时，第三接口23与第二接口22连通。由此，可以通过换向组件2方便地实现空调***100在不同工作模式之间的切换。例如，可以通过换向组件2实现冷媒流向的切换，进而实现空调***100在制冷模式、制热模式等之间的切换。
例如，当空调***100运行制冷模式时，可以使换向组件2的第一接口21与第四接口24连通，第三接口23与第二接口22连通。制冷模式下，冷媒可以依次经过压缩机1 的排气口11、换向组件2的第一接口21、第四接口24、室外换热器3、节流装置5、室内换热器4、换向组件2的第二接口22、换向组件2的第三接口23，最后从压缩机1的吸气口12回到压缩机1，如此循环。此时室内换热器4为蒸发器，室外换热器3为冷凝器。冷媒流经室内换热器4时，和空气进行换热，吸收空气中的热量，以此达到制冷的目的。
当空调***100运行制热模式时，通过换向组件2可以实现对冷媒流向的切换，换向组件2的第一接口21与第二接口22连通，第三接口23与第四接口24连通。制热模式下，冷媒依次经过压缩机1的排气口11、换向组件2的第一接口21、换向组件2的第二接口22、室内换热器4、节流装置5、室外换热器3、换向组件2的第四接口24、换向组件2的第三接口23，最后从压缩机1的吸气口12回到压缩机1，如此循环。此时室外换热器3为蒸发器，室内换热器4为冷凝器。冷媒流经室内换热器4时，和空气进行换热，向空气中释放热量，以此达到制热的目的。
冷媒支路6的进口61与排气口11相连，冷媒支路6的出口与吸气口12相连，冷媒支路6上设有第一换热装置71，第一换热装置71设在底盘8上。当冷媒支路6连通时，经压缩机1压缩后的高温冷媒可以经排气口11进入冷媒支路6，高温冷媒进入第一换热装置71后，可以对底盘8加热，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，进而可以避免底盘8上的积水打烂室外风机的风叶。进入第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
例如，在本申请的一些实施例中，当空调***100运行制热模式时，可以控制冷媒支路6连通，此时经压缩机1压缩的一部分高温冷媒进入室内换热器4中换热，经室内换热器4换热后的冷媒经节流装置5后进入室外换热器3中换热，经室外换热器3换热后的冷媒，经压缩机1的吸气口12进入压缩机1内压缩。与此同时，经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中，通过高温冷媒对底盘8加热，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，进而避免底盘8上的积水打烂室外风机的风叶。在第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
当空调***100运行除霜模式时，可以控制冷媒支路6连通，此时经压缩机1压缩的一部分高温冷媒进入室外换热器3中换热，经室外换热器3换热后的冷媒经节流装置5后进入室内换热器4中换热，经室内换热器4换热后的冷媒，经压缩机1的吸气口12进入压缩机1内压缩。与此同时，经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中，通过高温冷媒对底盘8加热，避免底盘8上的水结冰，从而 可以避免冰雪等堵塞底盘8的排水口，进而避免底盘8上的积水打烂室外风机的风叶。在第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
由此，通过设置冷媒支路6，并在冷媒支路6上设置第一换热装置71，可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，进而避免底盘8上的积水打烂室外风机的风叶，减少了空调***100的耗电量，有效地节约了能源。
例如，在本申请的一些具体实施例中，当空调***100运行制热模式时，可以获取室外温度T，当室外温度T大于第一预设值T1且小于第二预设值T2时，可以开启冷媒支路6，使得经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中，通过高温冷媒对底盘8加热，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，进而避免底盘8上的积水打烂室外风机的风叶。由此，可以在保证空调***100制热效果的同时，节约了能源。
可选地，第一预设值T1可以为0～3℃，第二预设值T2可以为5～10℃。例如，第一预设值T1可以为3℃，第二预设值可以为7℃。在本申请的一些实施例中，在空调***100运行制热模式时，当3℃＜T＜7℃时，可以开启冷媒支路6，使得部分冷媒进入第一换热装置71对底盘8加热。
在本申请的一些具体实施例中，当空调***100运行除霜模式时，可以获取室外温度T，当室外温度T大于第一预设值T3且小于第二预设值T4时，可以开启冷媒支路6，使得经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中，通过高温冷媒对底盘8加热，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，进而避免底盘8上的积水打烂室外风机的风叶。由此，可以在保证空调***100制热效果的同时，节约了能源。
可选地，第三预设值T3可以为-3～0℃，第四预设值T4可以为0～5℃。例如，第三预设值T1可以为0℃，第二预设值可以为3℃。在本申请的一些实施例中，在空调***100运行制热模式时，当0℃＜T＜3℃时，可以开启冷媒支路6，使得部分冷媒进入第一换热装置71对底盘8加热，避免融化水结冰，直至除霜动作结束。
根据本申请实施例的空调***100，通过设置冷媒支路6，并在冷媒支路6上设置第一换热装置71，可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，避免底盘8上的积水打烂室外风机的风叶。由此，可以在保证空调***100制热效果的同时，减少了空调***100的耗电量，节约了能源。
根据本申请的一些实施例，冷媒支路6的进口61包括第一进口611和第二进口612，第一进口611与第二接口22相连，第二进口612与第四接口24相连。当空调***100运行制热模式时，换向组件2的第一接口21与第四接口24连通，部分高温冷媒可以经第四接口24进入冷媒支路6。当空调***100运行除霜模式时，换向组件2的第一接口21与第二接口22连通，部分高温冷媒可以经第二接口22进入冷媒支路6。由此，在空调***100运行制热模式和除霜模式时，均可以使得部分高温冷媒进入冷媒支路6，通过高温冷媒对底盘8进行加热。
进一步地，第一进口611与第一换热装置71之间可以设有第一开关阀91。可选地，第一开关阀91可以为电磁阀。第一开关阀91打开时，第一进口611与第二接口22之间连通，当换向组件2的第一接口21与第二接口22连通时，冷媒可以进入冷媒支路6。第一开关阀91关闭时，第一进口611与第二接口22断开，此时冷媒不能进入冷媒支路6。例如，在除霜模式下，可以根据室外温度判断是否需要开启第一开关阀91。
第二进口612与第一换热装置71之间可以设有第二开关阀92。可选地，第二开关阀92可以为电磁阀。第二开关阀92打开时，当换向组件2的第一接口21与第四接口24连通时，冷媒可以进入冷媒支路6。第二开关阀92关闭时，第二进口612与第四接口24断开，此时冷媒不能进入冷媒支路6。例如，在制热模式下，可以根据室外温度判断是否需要开启第二开关阀92。
由此，通过设置第一开关阀91和第二开关阀92，可以根据实际运行情况控制冷媒支路6的通断，优化了空调***100的性能。
可以理解的是，在本申请的另一些实施例中，参照图2，冷媒支路6的进口61也可以连接在排气口11和换向组件2的第一接口21之间。这样，当冷媒支路6连通时，从排气口11排出的部分冷媒可以进入换向组件2，另一部分冷媒可以进入冷媒支路6。由此，在空调***100运行制热模式和除霜模式时，同样均可以使得部分高温冷媒进入冷媒支路6，通过高温冷媒对底盘8进行加热。
进一步地，冷媒支路6的进口61处可以设有第五开关阀95。可选地，第五开关阀95为电磁阀。
根据本申请的一些实施例，空调***100还包括第二换热装置72，第二换热装置72包括第一换热流路和第二换热流路，第一换热流路串联在第一换热装置71和吸气口12之间，第二换热流路串联在室内换热器4和室外换热器3之间。也就是说，从第一换热装置71中流出的冷媒可以进入第一换热流路，并流向吸气口12。从室内换热器4流出的冷媒可以进入第二换热流路并流向室外换热器3，或者从室外换热器3流出的冷媒可 以即进入第二换热流路并流向室内换热器4。
参照图1和图2，在制热模式下，当冷媒支路6打开时，从第一换热装置71中流出的冷媒可以流向第一换热流路，从室内换热器4流出的冷媒可以流向第二换热流路，第一换热流路内的冷媒和第二换热流路内的冷媒在第二换热装置72内换热后，第一换热流路中的冷媒可以流向压缩机1的吸气口12，第二换热流路中的冷媒可以经第一节流装置5节流后，进入室外换热器3内换热后流向压缩机1的吸气口12。这样，一方面，从第一换热装置71中流出的冷媒在第二换热装置72内换热后，可以吸收热量，提高温度，进而可以提升冷媒回气温度。另一方面，从室内换热器4流出的冷媒在第二换热装置72内换热后，温度降低，进而可以在室外换热器3中获取更多的热量，有利于提高制热效果。
根据本申请的一些实施例，冷媒支路6还包括分流支路62，分流支路62的第一端连接在第一换热装置71和第一换热流路之间，分流支路62的第二端连接在室外换热器3和室内换热器4之间。分流支路62打开时，从第一换热装置71流出的冷媒可以进入室内换热器4换热。
例如，当空调***100运行除霜模式时，在第一换热装置71内换热后的冷媒可以进入室内换热器4换热后流向吸气口12，由此有利于提高冷媒的回气温度。
在本申请的一些实施例中，分流支路62的第二端可以连接在室外换热器3和节流装置5之间。当空调***100运行除霜模式时，在第一换热装置71内换热后的冷媒，先经节流装置5节流后，进入室内换热器4换热后流向吸气口12，由此有利于提高冷媒的回气温度。
根据本申请的一些实施例，分流支路62上设有第三开关阀93，第三开关阀93可以打开或者关闭分流支路62。可选地，第三开关阀93为电磁阀。分流支路62的第一端与第一换热流路之间设有第四开关阀94。可选地，第四开关阀94为电磁阀。第四开关阀94打开时，从第一换热装置71流出的冷媒可以经第一换热流路流向吸气口12。第四开关阀94关闭时，从第一换热装置71流出的冷媒可以经分流支路62流向室内换热器4，进而流向吸气口12。
例如，空调***100制热运行时，可以打开第四开关阀94，并关闭第三开关阀93。当空调***100运行除霜模式时，可以打开第三开关阀93并关闭第四开关阀94。由此，可以根据空调***100的实际运行情况控制冷媒支路6中冷媒的流向，有利于优化空调***100的性能。
根据本申请的一些实施例，空调***100还包括电加热件81，如图3所示，电加热 件81设在底盘8上。电加热件81可以用于辅助加热底盘8，避免底盘8加热。
例如，当室外温度较低，通过冷媒支路6内的冷媒已经提供足够的热量来融化底盘8上的冰雪时，可以开启电加热件81，利用电加热件81加热底盘8，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口。由此，可以根据实际需要，选择不同的加热方式，在保证空调***100制热效果的同时，节约了能源。
根据本申请的一些实施例，第一换热装置71包括相对设置的第一换热部711、第二换热部712和连接部713，第一换热部711和第二换热部712分别连接在连接部713的两端且彼此相对设置。可选地，电加热件81设置在第一换热部711和第二换热部712之间。由此，可以使得第一换热装置71和电加热件81的排布更加紧凑，有利于减小第一换热装置71和电加热件81的整体占用空间，使得底盘8上各部件的排布更加合理。
可选地，第一换热装置71可以为U形换热管。U形管换热器的换热面积大，且结构简单、紧凑、密封性能高，不仅安装方便，后期检修、清洗也方便。
图4示出了根据本申请实施例的空调***100的控制方法的控制流程图。
如图4所示，根据本申请第二方面实施例的空调***100的控制方法，包括：
判断空调***100是否开启制热运行或是否进入除霜模式；
若空调***100开启制热运行或进入除霜模式，获取当前室外温度T；
在空调***100制热运行时，若室外温度T大于第一预设值T1且小于第二预设值T2，控制冷媒支路6连通；
在空调***100进入除霜模式时，若室外温度T大于第三预设值T3且小于第四预设值T4，控制冷媒支路6连通。
在制热模式下，当室外温度T满足T1＜T＜T2时，可以控制冷媒支路6打开，此时经压缩机1压缩的一部分高温冷媒进入室内换热器4中换热，经室内换热器4换热后的冷媒经第一节流装置5后进入室外换热器3中换热，经室外换热器3换热后的冷媒，经压缩机1的吸气口12进入压缩机1内压缩。与此同时，经压缩机1压缩的另一部分高温冷媒可以经冷媒支路6进入第一换热装置71中，通过高温冷媒对底盘8加热，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，在第一换热装置71内换热后的冷媒经压缩机1的吸气口12进入压缩机1内压缩。
由此，可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口。
例如，在本申请的一些实例中，第一预设值T1可以为0～3℃，第二预设值T2可以 为5～10℃。例如，第一预设值T1可以为3℃，第二预设值可以为7℃。在本申请的一些实施例中，在空调***100运行制热模式时，当3℃＜T＜7℃时，可以开启冷媒支路6，使得部分冷媒进入第一换热装置71对底盘8加热。
第三预设值T3可以为-3～0℃，第四预设值T4可以为0～5℃。例如，第三预设值T1可以为0℃，第二预设值可以为3℃。在本申请的一些实施例中，在空调***100运行制热模式时，当0℃＜T＜3℃时，可以开启冷媒支路6，使得部分冷媒进入第一换热装置71对底盘8加热，避免融化水结冰，直至除霜动作结束。
根据本申请第二方面实施例的空调***100的控制方法，通过设置冷媒支路6，并在冷媒支路6上设置第一换热装置71，可以通过压缩机1压缩后的一部分高温冷媒加热底盘8上的水，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口，避免底盘8上的积水打烂室外风机的风叶。由此，可以在保证空调***100制热效果的同时，减少了空调***100的耗电量，节约了能源。
根据本申请的一些实施例，在空调***100运行制热模式时，当室外温度T大于等于第二预设值T2时，室外温度T较高，空调器***基本不会结冰且制热能力能够充分保证，此时可以关闭冷媒支路6。可以理解的是，当底盘8上设有电加热件81时，在空调***100运行制热模式时，当室外温度T大于等于第二预设值T2时，电加热件81也关闭。由此，可以保证空调***100制热能力的同时，减少耗电量。
进一步地，当底盘8上设有电加热件81时，在空调***100运行除霜模式时，当室外温度T小于等于第一预设值T1时，可以打开电加热件81，通过电加热件81对底盘8进行加热，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口。
例如，在除霜模式下，当室外温度小于等于0℃时，可以打开电加热件81，通过电加热件81对底盘8进行加热，避免底盘8上的水结冰，从而可以避免冰雪等堵塞底盘8的排水口。
在本申请的一些进一步实施例中，开启电加热件81后，可以根据室外温度T调整电加热件81的输出功率，在节能的同时实现底盘8不结冰。
例如，在本申请的一些实施例中，当T≤﹣15℃，可以关闭冷媒支路6，并控制电加热件81以最大功率W1运行，直至除霜动作结束。确保底盘8化霜的水滴可以及时排除底盘8，避免其结冰打烂风叶。
当-15℃<T≤-8℃，可以关闭冷媒支路6，并控制电加热件81以功率W2运行，直至除霜动作结束。其中W1>W2。在保证底盘8化霜的水滴及时排除的同时降低电加热件81的功耗，节约电能。
当-8℃<T≤-2℃，可以关闭冷媒支路6，并控制电加热件81以功率W3运行，直至除霜动作结束。其中W1>W2>W3。在保证底盘8化霜的水滴排除效率的同时降低电加热件81功耗，进一步节约电能。
当-2℃<T≤0℃，可以关闭冷媒支路6，并控制电加热件81以功率W3运行，直至除霜动作结束。其中W1>W2>W3>W4。在保证底盘8化霜的水滴排除效率的同时降低电加热管功耗，进一步节约电能。
