第一连接管11的第一端连接于第一单向阀24和第一冷凝器23之间的第一管道25上，第二端连接于第二冷凝器33和储液罐34之间的第二管道35上，且第一连接管11上设置有第一电磁阀101；
第二连接管12的第三端连接于第一单向阀24和第一蒸发器21之间的第一管道25上，第四端连接于制冷剂泵31和第二蒸发器32之间的第二管道35上，且第二连接管12上设置有第二电磁阀102；
旁通管7的两端分别连接压缩机22相对的两端，且旁通管7上设置有旁通单向阀71。
需要说明的是，该装置具有多种运行模式，包括：
①第一种模式：先开启压缩机22，旁通单向阀71单向截止，制冷剂泵31关闭、第一电磁阀101和第二电磁阀102均关闭，此时相当于只运行第一循环回路，第一循环回路为空调装置的常用循环之一，能满足空调装置的正常使用。
②第二种模式：关闭压缩机22、第一电磁阀101和第二电磁阀102均关闭，开启制冷剂泵31。此时，相当于只运行第二循环回路，第二循环回路为空调装置的常用循环之一，同样用于满足空调装置的正常使用。
③第三种模式：开启压缩机22，旁通单向阀71单向截止，第一电磁阀101和第二电磁阀102均关闭，开启制冷剂泵31。此时，相当于第一循环回路和第二循环回路分别独立地运行。
④第四种模式：关闭压缩机22，旁通单向阀71打开，第一电磁阀101和第二电磁阀102均开启，开启制冷剂泵31。此时，存在两种循环支路，一个循环支路为制冷剂泵31-第二电磁阀102-第一蒸发器21-旁路单向阀71-第一冷凝器23-第一电磁阀101-储液罐34-制冷剂泵31；另一个循环支路为制冷剂泵31-第二蒸发器32-第二冷凝器33-储液罐34-制冷剂泵31。 在第四种模式中，明显可以将第一冷凝器23、第二冷凝器33、第一蒸发器21和第二蒸发器32均利用起来，从而能够有效提升多模式循环空调装置在低温季节的使用能效比。
还需补充说明的是，在第四种模式中，能有效增大多模式循环空调装置中的冷量调节范围。在现有的空调装置中，因压缩机存在最低转速限制，对低负载的调节能力较差，一般只能设定在30％-100％范围内输出冷量。本实施例中设置有第一连接管11、第二连接管12和旁通管7，可以在低负载时通过制冷剂泵31调节冷量的输出，从而实现0％-100％的冷量调节。
请参阅图2，在一个具体的实施方式中，多模式循环空调装置还包括第三连接管13和第四连接管14；
第二蒸发器32和第二冷凝器33之间的第二管道35上设置有第二单向阀36；
第三连接管13的第五端连接于压缩机22和第一冷凝器23之间的第一管道25上，第六端连接于第二单向阀36和第二冷凝器33之间的第二管道35上，且第三连接管13上设置有第三电磁阀103；
第四连接管14的第七端连接于第一蒸发器21和压缩机22之间的第一管道25上，第八端连接于第二蒸发器32和第二单向阀36之间的第二管道35上，且第四连接管14上设置有第四电磁阀104。
具体地，在本实施例中，延伸出第五种模式，具体地为：
⑤第五种模式：开启压缩机22，旁通单向阀71单向截止，第二单向阀36单向截止，第一电磁阀101和第二电磁阀102均关闭，第三电磁阀103和第四电磁阀104均开启，开启制冷剂泵31。此时，存在两个支路循环，一个为压缩机22-第一冷凝器23-第一单向阀24-第一蒸发器21-压缩机22；另一循环为压缩机22-第三电磁阀103-第二冷凝器33-储液罐34-制冷剂泵31-第二蒸发器32-第四电磁阀104-压缩机22。第五种模式中主要用于高温季节，同样能有效利用第一冷凝器23、第二冷凝器33、第一蒸发器21和第二蒸发器32，提升换热效果，提升能效比。
请参阅图3，在另一个具体的实施方式中，多模式循环空调装置还包括第五连接管15；
第五连接管15的第九端连接于第一电磁阀101和第一管道25之间的第一连接管11上，第十端连接于第三连接管13上；
第五连接管15上设置有第五电磁阀105。
本实施例中，可以延伸出第六种模式，具体为：
⑥第六种模式：循环为压缩机22-第一冷凝器23-第五电磁阀105-第三电磁阀103-第二冷凝器33-储液罐34-制冷剂泵31-第二电磁阀102-第一蒸发器21-压缩机22。本实施例中，冷媒可以直接接入第一冷凝器23和第二冷凝器33，有利于降低整个循环系统的循环压力，同时使进入第一电子膨胀阀26的冷媒的过冷度增加，提升冷循环的单位制冷量，从而有利于提升制冷效率。
请参阅图3，在另一个具体的实施方式中，多模式循环空调装置还包括第六连接管16；
第六连接管16的第十一端连接于第二电磁阀102和第一管道25之间的第二连接管12上，第十二端连接于第四连接管14上；
第六连接管16上设置有第六电磁阀106。
具体地，本实施例可以延伸出第七种模式，具体为：
⑦第七种模式：循环为压缩机22-第一冷凝器23-第一电磁阀101-储液罐34-制冷剂泵31-第二蒸发器32-第四电磁阀104-第六电磁阀106-第一蒸发器21-压缩机22。本实施例中，可以同时为两个房间输送冷量，满足多场所的使用的需求。

具体地，通过蒸发风机4同时对第一蒸发器21、第二蒸发器32进行冷却，且第一温度传感器51检测出风温度，在第一温度传感器51检测到出风温度超过设定值时蒸发风机4增大转速来增加出风量，以确保冷却效果。
可选地，多模式循环空调装置还包括用于提升第一冷凝器23和第二冷凝器33换热量的冷凝风机6；
第一冷凝器23、第二冷凝器33和冷凝风机6沿冷凝风机6的出风方向依次设置，且冷凝风机6的出风端设置有第二温度传感器52；
第二温度传感器52与冷凝风机6电连接。
具体地，通过冷凝风机6同时对第一冷凝器23、第二冷凝器33进行冷却，且第二温度传感器52检测出风温度，在第二温度传感器52检测到出风温度超过设定值时冷凝风机6增大转速来增加出风量，以确保冷却效果。
