根据本申请的一个方面提供了一种两管制喷气增焓多联机***，两管制喷气增焓多联机***包括如上述任一实施例的两管制喷气增焓室外机，因此，该两管制喷气增焓多联机***具有如上述任一实施例的两管制喷气增焓室外机的全部有益效果。

如图3所示，制冷时，高温高压气态冷媒从喷气增焓压缩机16出来，首先经过换向组件18，和第四单向阀34进入室外换热器10冷凝，冷凝后的高压液态冷媒经过第一单向阀28后，冷媒进入过冷器20主路入口，另外一部分冷媒经过节流组件22节流后从过冷器20辅路入口进入过冷器20，从过冷器20辅出口流出，然后经过第一电磁阀26进入喷射口166。从过冷器20主路入口进入过冷器20冷凝成过冷的高压液态冷媒从过冷器20主路出口流出经过第二单向阀30从高压阀经过进入制冷剂流向切换装置46入口，从制冷剂流向切换装置46气液分离器液侧出口流出，经过制冷剂流向切换装置46第一过冷装置和第二过冷装置过冷后，经过制冷单向阀和内机电子膨胀阀从液管进入两管制喷气增焓室内机44，在两管制喷气增焓室内机44蒸发换热后，形成的低压气态冷媒通过回气管低压阀回到两管制喷气增焓室外机，经过单向阀第六单向阀38和换向组件18回到低压罐，再回到回气口164。
如图4所示，制热时，高温高压气态冷媒从喷气增焓压缩机16出来，分别经过第二电磁阀42和换向组件18及第七单向阀40两路到高压阀，再从高压阀通过高压管流到制冷剂流向切换装置46入口，进入气液分离器，从气液分离器气侧出口经过制热电磁阀从气管进入两管制喷气增焓室内机44，在两管制喷气增焓室内机44被冷凝成高压液态冷媒后，流过两管制喷气增焓室内机44电子膨胀阀，变成高压两相冷媒，流过制冷剂流向切换装置46的节流元件回到低压管经过低压阀进入两管制喷气增焓室外机，经过第三单向阀32后进入过冷器20主路入口，从过冷器20主路出口，出来后，冷媒一部分通过节流组件22变成低压两相态冷媒进入室外换热器10吸热，然后经过换向组件18回到低压罐，随后进入回气口164；另外一部分冷媒通过节流组件22后进入过冷器20辅路入口，从过冷器20辅路出口出来后， 中压气态冷媒经过第一电磁阀26进入压缩机压缩腔。
图7所示的压焓图表明本申请提供的两管制喷气增焓多联机***可显著增加制热内机的能力，尤其是在低温工况下。图中C点所示为喷气增焓压缩机喷气口状态，主路冷媒先通过低压腔进入喷气增焓压缩机，被压缩到B点后，与C点喷入喷气增焓压缩机的冷媒混合达到D状态，再继续压缩。从喷气口C喷入压缩机的冷媒是中压冷媒，密度比回气口A点的冷媒密度大的多，使得冷媒循环量大大增加，同时排气过热度降低，可以增大压比。从而使得制热能力得到极大提高。
如图7所示，制冷时，***可以有更低的过冷度，因此用更低的冷媒循环量可以实现相同的制冷能力，从而提高能效。由于喷焓时排气过热度SH＜SH’，高温制冷时，***频率可以跑的更高而提高高温制冷能力。
如图5所示为两管制喷气增焓多联机***在主制热模式下的示意图，其中管路内的冷媒流向如图中所示，如图6所示为两管制喷气增焓多联机***在主制冷模式下的示意图，其中管路内的冷媒流向如图中所示。
