所述室外机1包括压缩机11、两个室外换热单元12和阀组件13，所述高压气管5与所述压缩机11的排气口连通，所述低压气管6与所述压缩机11的吸气口连通，一个所述室外换热单元12具有一端与所述高压气管5连通且另一端与所述液管4连 通的第三状态和一端与所述低压气管6连通且另一端与所述液管4连通的第四状态，从而满足在第三状态下该室外换热单元12进行冷凝，在第四状态下该室外换热单元12进行蒸发的目的。
另一所述室外换热单元12具有一端与所述液管4连通且另一端通过所述阀组件13与所述高压气管5连通的第五状态和一端与所述液管4连通且另一端通过所述阀组件13与所述低压气管6连通的第六状态，且所述阀组件13控制所述室外换热单元12在所述第五状态和所述第六状态之间切换，通过采用两个室外换热单元12，能够根据所有所述室内换热机构2的需求分别调节两个室外换热单元12的工作状态，进而保证冷凝和蒸发的换热面积与需求匹配的目的，增加系统的舒适性，而且通过阀组件13，能够调节对应的室外换热单元12的工作状态，也即调节室外换热单元12或与高压气管5连通进行冷凝、或与低压气管6连通进行蒸发、或与高压气管5和低压气管6均不连通而不进行工作的三种状态，进而满足压缩机11在不降频的条件下切换空调系统的工作状态的目的，能够有效的降低主阀体在切换过程中产生的噪音。
所述阀组件13包括高压电磁阀131和低压电磁阀132，所述高压电磁阀131的一端形成所述阀组件13的高压入口，另一端形成所述阀组件13的高压出口，所述低压电磁阀132的一端与所述高压出口连通，另一端形成所述阀组件13的低压出口，且所述高压入口直接或间接与所述压缩机11的排气口连通，所述高压出口与对应的所述室外换热单元12连通，所述低压出口与所述低压气管6连通，利用高压电磁阀131和低压电磁阀132对对应的室外换热单元12的压力值进行快速调节，降低主阀体在切换时需要克服的压力值，进而不需要压缩机11进行降频操作，并且保证主阀体在切换状态时，不会产生过大噪音。

如以图1中的室内换热机构2为例：其中室内换热机构2包括两个空调室内机21、一个制冷水机构、一个制热水机构和一个地暖管路33；
1、在空调系统有室内制冷需求、制冷水需求或两种需求同时存在时，外机运行状态一致：制冷四通阀14掉电(制冷四通阀14的D端与C端连通)，外侧换热器作为冷凝器，将高温高压气体冷却为低温高压液体，经过外机EEV节流后，变为低温低压液体经过液管4进入模式转换器。
冷媒进入模式转换器后，对于有空调制冷的内机支路和有制冷水需求的支路，对应支路的第一电磁阀(或第三电磁阀)处于掉电状态，第二电磁阀(或第四电磁阀)处于上电状态，对于空调室内机21来讲，冷媒经过内机EEV后进入内侧换热器进行蒸发，通过低压气管6回到外机；对于制冷水机构，冷媒经过发生器31与水换热后回到外机。而发生器31中吸收冷媒能量的水降至我们所需要的温度进入水箱32储存，便于生活实用。
2、在空调系统有室内制热需求、制热水、地暖采暖需求或几种需求同时存在时，外机运行状态一致：制冷四通阀14上电(制冷四通阀14的D端与E端连通)。系统启动时，高温高压气体直接经过高压气管5进入模式转换器。
高温冷媒进入模式转换器后，对于进行制热的空调室内机21和制热水机构，对应支路的第一电磁阀处于上电状态，第二电磁阀处于掉电状态，对于控制制热支路来讲，高温冷媒通过气管进入空调室内机21冷凝后经液管4回到外机换热器蒸发，之后回到压缩机11；对于制热水机构，高温冷媒经过发生器31对水进行加热，换热后也是经液管4回到外机换热器；经过发生器31加热的水加热到目标温度后，就会储存在水箱32进行保温，供人们日常使用；对于需要地暖采暖需求的支路，就直接利用高温冷媒对水进行加热，供日常取暖使用。
3、在空调系统需要实现同时空调制冷、空调制热、生活冷水、生活热水、地暖采暖功能时，外机运行状态为：制冷四通阀14上电(制冷四通阀14的D端与E端连通)。系统启动时，高温高压气体直接经过高压气管5进入模式转换器。
其中分支1至分支5沿图1中远离室外机1的方向依次设置：
分支1(空调室内机21制冷)：空调制冷：第三电磁阀关闭，第四电磁阀上电，冷媒经过液管4进入内机，换热后，经低压气管6回到外机；
分支2(空调室内机21制热)：空调制热：第三电磁阀上电，第四电磁阀掉电，冷媒经过高压气管5进入内机，换热后经过液管4一部分进入到制冷内机中，一部分回到外机系统中。
分支3(制热水机构)：生活热水：第一电磁阀上电，第二电磁阀掉电，冷媒经过高压气管5进入发生器31，换热后经过液管4一部分进入到制冷内机中，一部分回到外机系统中。经过发生器31加热的水加热到目标温度后，就会储存在水箱32进行保温，供人们日常使用
分支4(制冷水机构)：生活冷水：第一电磁阀关闭，第二电磁阀上电，冷媒经过液管4进入发生器31，换热后，经低压气管6回到外机，发生器31中吸收冷媒能量的水降至我们所需要的温度进入水箱32储存，便于生活实用。
分支5(地暖管路33)：地暖采暖：第一电磁阀上电，第二电磁阀掉电，冷媒经过高压气管5进入发生器31，换热后经过液管4一部分进入到制冷内机中，一部分回到外机系统中，而在发生器31中换热后的水进入地暖管道，供日常取暖使用。
以上所述实施例仅表达了本公开的几种实施方式，其描述较为具体和详细，但并不能因此而理解为对本公开专利范围的限制。应当指出的是，对于本领域的普通技术人员来说，在不脱离本公开构思的前提下，还可以做出若干变形和改进，这些都属于本公开的保护范围。因此，本公开专利的保护范围应以所附权利要求为准。
