本发明的再一个目的在于提供一种空调。
为实现上述目的，本发明第一方面技术方案提供了一种空调系统，包括：压缩机、室外换热器、室内换热器以及设于压缩机、室外换热器以及室内换热器之间，用于切换制冷模式和制热模式的四通阀，该空调系统还包括：第一分离器，连接于室外换热器与室内换热器之间，第一分离器的第一口与室外换热器管路连接，第一分离器的第二口与室内换热器管路连接；辅助支路，与室内换热器并联于气液分离器与四通阀之间，辅助支路的一端与气液分离器的第三口相连，其中，气液分离器的第三口为气相出口。
在该技术方案中，通过在室外换热器与室内换热器之间，设置第一分 离器，制冷时，压缩机排出的高温高压蒸汽经四通阀流入室外换热器，制冷剂在室外换热器中部分冷凝成液，部分成气态，气液两相的制冷剂在第一分离器中进行气液分离，分离后气态制冷剂从第一分离器的第二口连通到室内换热器出口，液态制冷剂从第一分离器的第一口进入蒸发器后进行蒸发换热，之后在蒸发器出口处与旁通过来的气态制冷剂混合，混合后制冷剂蒸汽经四通阀进入低压罐后回到压缩机，由于气态制冷剂比体积大，会产生较大的流动阻力，该辅助支路的设置大大提升了系统能效；另外，制热模式运行下，由室内换热器进入第一分离器的制冷剂为液态，此时第一分离器可以存储较大量的制冷剂，从而减少了由于制热时室内换热器容积小导致制冷剂充注过量的可能性。
另外，本发明提供的上述技术方案中的空调系统还可以具有如下附加技术特征：
在上述技术方案中，优选地，辅助支路包括：相互串联的毛细管以及单向阀，其中在冷媒由气液分离器流向四通阀时，单向阀导通。
在该技术方案中，通过相互串联的毛细管以及单向阀，在冷媒由气液分离器流向四通阀时，导通的单向阀可避免因旁通支路压损过低导致气液分离器里有更多的冷媒蒸发成气态经旁通支路直接到蒸发器出口，导致额外的冷量损失；在制热时，压缩机排出的高温高压制冷剂蒸汽经四通阀流通到室内换热器，由于单向阀单向导通的特性，高温高压蒸汽无法通过辅助支路进入气液分离器，减少了热能的浪费。
在上述任一技术方案中，优选地，还包括：第二分离器，设于四通阀与压缩机之间，第二分离器对流入压缩机的冷媒进行气液分离。
在该技术方案中，通过在四通阀与压缩机之间设置第二分离器，对流入压缩机的冷媒进行气液分离，储存多余液体，以减少大量液体涌入压缩机，起到调节流量的作用。
在上述任一技术方案中，优选地，四通阀包括：第一阀口，与压缩机的排气口管路连接；第二阀口，与室外换热器相连；第三阀口，与第二分离器的进气口相连，冷媒经第二分离器的出气口通过管路排入压缩机的回气口；第四阀口，与室内换热器相连。
在该技术方案中，通过四通阀的四个阀口的启闭，可快速完成制冷和制热的切换，提高了效率并简化了工作。制冷循环时，从压缩机排出的高温高压蒸汽经第一、第二阀口进入到室外换热器，冷凝后经第一分离器进行气液分离，其中的液态制冷剂从第一分离器进入蒸发器进行换热，再与辅助支路的气态制冷剂混合，经四通阀的第三、四阀口回到压缩机，完成制冷循环；制热循环时，从压缩机排出的高温高压蒸汽制冷剂经第一、四阀口进入到室内换热器，冷凝后经第一分离器进行气液分离，进入蒸发器进行吸热蒸发，蒸发后的制冷剂蒸汽经四通阀的第助支路的气态制冷剂混合，经四通阀的第二、第三阀口进入第二分离器，最终进入压缩机，完成制热循环。
在上述任一技术方案中，优选地，还包括：微控制器，与四通阀电连接，空调系统处于制冷模式时，微控制器控制四通阀的第一阀口与第二阀口连通，第三阀口与第四阀口连通，空调系统处于制热模式时，微控制器控制四通阀的第一阀口与第四阀口相连，第二阀口与第三阀口相连。
在该技术方案中，通过与四通阀电连接的微控制器，在制冷模式时控制四通阀的第一阀口与第二阀口连通，使压缩机排出的高温高压蒸汽流通到室外换热器中冷凝；第三与第四阀口连通，使蒸汽换热后的制冷剂从蒸发器流通到第二分离器中；在制热模式时，微控制器控制四通阀第一阀口与第四阀口相连，使压缩机排出的高温高压蒸汽流通到室内换热器中冷凝；第二阀口与第三阀口相连，使吸热蒸发后的制冷剂从蒸发器流通到第二分离器中。
在上述任一技术方案中，优选地，辅助支路包括：单向节流阀，设于辅助支路上，单向节流阀单向导通由第一分离器流向四通阀的冷媒。
在该技术方案中，通过在辅助支路上设置单向节流阀，对第一分离器流向四通阀的冷媒进行单向导通，可在制冷模式时，让气态制冷剂从单向阀流向四通阀，减小了液态制冷剂从蒸发器流通时的流动阻力，提升了系统能效；制热模式时，压缩机排出的高温高压制冷剂蒸汽经四通阀流向室内换热器，仅单向导通的单向阀阻止高温高压蒸汽制冷剂进入气液分离器，从而减少了热能的浪费。
在上述任一技术方案中，优选地，还包括：节流件，设于连接室外换热器以及第一分离器的第一口的管路上，节流件对在连接室外换热器以及第一分离器的管路中流动的冷媒进行降温降压处理。
在该技术方案中，通过节流件的设置，在室外换热器中冷凝的高温高压液态制冷剂经节流件，形成了低温低压的气液两相制冷剂，有利于蒸汽换热，从而提高系统能效。
本发明第二方面的技术方案还提供了一种空调，该空调包括上述第一方面技术方案中任一空调系统。
在该技术方案中，通过采用上述任一项方案的空调系统，可以减少普通空调室内换热器容积小，制热时制冷剂充注量过量，系统运行不良的可能性，同时还可以提升空调整体的能效。
在上述任一技术方案中，优选地，还包括：信号接收器，与空调系统中的微控制器电连接，信号接收器接收外界信号并向微控制器发送控制信号，微控制器响应于控制信号切换空调的运行模式。
在该技术方案中，通过与空调系统中的微控制器电连接信号接受器，可接收到外界信号并向微控制器发送控制信号，微控制器响应于控制信号切换空调的运行模式，从而实现空调的遥控，使的空调的调节操作更加便利和人性化。
在上述任一技术方案中，优选地，信号接收器包括：红外传感器、蓝牙接收器、WIFI接收器。
在该技术方案中，通过选用红外传感器、蓝牙接收器、WIFI接收器等不同的信号接收器，可以实现遥控器遥控、语音遥控、手机遥控等多种遥控方式，进一步简化了空调的操控，提高了操控的便利性、舒适性。

在下面的描述中阐述了很多具体细节以便于充分理解本发明，但是，本发明还可以采用其他不同于在此描述的其他方式来实施，因此，本发明的保护范围并不受下面公开的具体实施例的限制。

具体实施例：
本发明中的一个具体实施例中，如图3所示的空调系统，包括：压缩机102、室外换热器112、室内换热器120以及设于压缩机102、室外换热器112以及室内换热器120之间，通过微控制器控制的用于切换制冷模式和制热模式的四通阀114，该空调系统还包括：第一分离器108，连接于室外换热器112与室内换热器120之间，第一分离器108的第一口与室外换热器112管路连接，第一分离器108的第二口106与室内换热器120管路连接；辅助支路，与室内换热器120并联于气液分离器与四通阀114之间，辅助支路的一端与气液分离器的第三口122相连，其中，气液分离器的第三口122为气相出口；节流件110，连接于第一分离器108和室外换热器112之间；第二分离器104，连接于四通阀114和压缩机102之间。
在该具体实施例中，室内换热器选用微通道换热器，其内容积远远小于常规换热器内容积，在制冷模式中，压缩机102排出的高压高温蒸汽经四通阀114流入室外换热器112；制冷剂在室外换热器112中冷凝成液；高温高压的液态制冷剂经节流件节流后，形成低温低压的气液两相制冷剂；气液两相的制冷剂在第一分离器108中进行气液分离，分离后气态制冷剂从辅助支路经单向阀118连通到室内换热器120出口而液态制冷剂从第一分离器108的进入蒸发器后进行蒸发换热，之后在蒸发器出口处与旁通过来的气态制冷剂混合；气态制冷剂的比体积大，有较大的流动阻力，从辅助支路流通，减小了液态制冷剂进入蒸发器的阻力，提升了系统能效；混合后的制冷剂蒸汽经四通阀114进入第二分离器104后回到压缩机102；制热模式运行下，压缩机102排出的高温高压制冷剂蒸汽经四通阀114流通到室内换热器120，此时，由于单向阀118仅能单相导通，因此高温高压制冷剂蒸汽无法通过旁通支路进入气液分离器，减少了热能的浪费。高温高压的制冷剂蒸汽经室内换热器120冷凝后，形成液态制冷剂经气液分离器流通到节流件110，节流后低温低压的制冷剂在室外换热器112中从环境中吸热蒸发，蒸发后的制冷剂蒸汽经四通阀114进入第二分离器104 再回到压缩机102，由于第一分离器108处于室内换热器120与节流件110之间，在制热运行模式下进入第一分离器108的制冷剂为液态，因而此时第一分离器108可以存储较大量的制冷剂，从而减少了热泵空调室内换热器120过小时制冷、制热制冷剂充注量不平衡的可能性。
以上结合附图详细说明了本发明的技术方案，本发明提供了一种空调系统和空调，通过在室外换热器和室内换热器之间连接的第一分离器，以及连接在第一分离器和四通阀之间的辅助支路，实现了气液两态的制冷剂分离流通，减小了液态制冷剂的流通阻力，提高了空调系统的能效，同时，第一分离器还在制热循环时，可以存储较大量的液态制冷剂，在不增加室内换热器内容及的前提下，解决了热泵空调室内换热器过小时制冷、制热制冷剂充注量不平衡的问题，降低了成本，节省了空间。
