在现有的一些联供系统中，一次系统和二次系统之间增加了储能设备，如水箱、胆等，其中一次系统包括热源设备，二次系统包括换热末端，通过储能设备实现一次系统和二次系统之间的温度和压力耦合功能，即储能设备起到储能和缓冲的功能。
应该注意，上面对技术背景的介绍只是为了方便对本申请的技术方案进行清楚、完整的说明，并方便本领域技术人员的理解而阐述的。不能仅仅因为这些方案在本申请的背景技术部分进行了阐述而认为上述技术方案为本领域技术人员所公知。
发明内容
发明人发现，在现有的包含储能设备的联供系统中，热源设备流出的流体流入储能设备，和储能设备中的流体混合之后再供应换热末端，热源设备流出的流体不能直接流入换热末端，进而不能实现快速的制热或制冷，另外，当热源设备包括多个热源时，不同热源流出的流体也会在储能设备中混合之后再供应换热末端，使得能够提供较高温度的流体的热源中的高温流体无法直接被供应到换热末端以实现快速制热，同理，低温热源的低温流体也无法直接被供应到换热末端以实现快速制冷。
针对上述问题中的至少之一，本申请实施例提供一种换热系统，可以在对一次系统和二次系统进行耦合的基础上，使换热系统中的流体能够直接地被供应至换热末端，从而实现快速制热/制冷。

第一方面的实施例
本申请第一方面的实施例提供一种换热系统，图1是本申请实施例的换热系统的一 个示意图，如图1所示，该换热系统包括：胆10、第一热源20、换热末端30，第一热源20的出口21用于通过第一管路41和胆10的第一入口11连接，换热末端30的入口31用于通过第二管路42和胆10的第一出口12连接，换热系统还包括第三管路43，第三管路43用于将第一管路41中的至少部分流体引导至第二管路42或换热末端30，如第三管路43可用于将第一管路41中的一部分流体引导至第二管路42或换热末端30，或者，第三管路43可用于将第一管路41中的全部流体引导至第二管路42或换热末端30。
由此，通过第三管路43将第一管路41中的至少部分流体引导至第二管路42或换热末端30，第一热源20中的高温流体或低温流体可直接供应换热末端30，从而实现快速制热或制冷，同时，第一热源20、换热末端30均连接胆10，能够通过胆10实现一次系统和二次系统之间耦合功能。
在本申请实施例中，换热系统中的流体可以为常用的各种冷媒，如低温冷水、氟利昂等，也可以为各种常用的热媒，如热水等，本申请对此不作限制，可根据实际需要而选择合适的流体，胆可存储换热系统中的流体，从而平衡第一热源侧和换热末端侧的压力、温度，也即实现一次系统和二次系统之间的耦合功能，胆可以为开放式，如一端具有开口而使胆内存储的流体与外部接触，或者，胆也可以为封闭式。值得注意的是，在以下说明中，如无特别指出，以水作为流体的例子进行说明，但本申请不限于此。
在本申请实施例中，第一热源可以为换热系统中常用的热源设备，只要第一热源能够提供如下功能：制热功能，或者制冷功能，或者即可提供制热功能又可提供制冷功能，换言之，第一热源可向第一管路中提供高温热媒以制热，或者可向第一管路中提供低温冷媒以制冷，或者可以根据需要向第一管路中提供高温热媒或低温冷媒。但不限于此，第一热源还可以提供其他功能，例如第一热源还可以提供生活用水，如热水或冷水，可根据实际需要选择具有相应功能的第一热源。
例如，在本申请实施例中，第一热源可以为以下设备中的任意一者或组合：燃气热水装置、电热水装置、热泵和太阳能热水器，其中电热水装置、燃气热水装置均可用于提供生活用水，也均可用于采暖，如电热水装置、燃气热水装置可以为壁挂炉，热泵可用于制冷或制热。例如，第一热源可以包括一个或多个燃气热水装置，多个燃气热水装置可以串联和/或并联，或者，第一热源可以包括一个或多个电热水装置，多个电热水装置可以串联和/或并联，或者，第一热源可以包括一个或多个热泵，多个热泵可以串联和/或并联，或者，第一热源可以包括至少一个燃气热水装置和至少一个热泵，燃气热水装 置和热泵可以串联或并联，或者，第一热源可以包括至少一个电热水装置和至少一个热泵，电热水装置和热泵可以串联或并联，或者，第一热源可以包括至少一个燃气热水装置和至少一个电热水装置，燃气热水装置和电热水装置可以串联或并联。
在本申请实施例中，第一热源可以为多个子热源的组合，各个子热源中的流体通过与各自对应的第三管路被引导至第二管路或换热末端，第三管路的数量为至少一个，也就是说，多个子热源可通过串联和/或并联的方式构成第一热源，各个子热源可通过分别与其对应的相同的第三管路或不同的第三管路将其流体引导至第二管路或换热末端，其中各子热源可以为燃气热水装置、电热水装置、热泵、太阳能热水器中的任意一者。可根据实际需要而选择合适的第一热源。
在本申请实施例中，换热末端可以为常见的换热系统的末端设备，例如可以为风盘、地暖、散热器、其它形式的换热器等设备中的至少一者，本申请对此不作限制，其中，其它形式的换热器可以为换热系统的除了风盘、地暖、散热器之外的其它的换热末端设备，此外，换热末端的数量也可以为一个或多个，值得注意的是，此处的换热末端的数量表示换热末端的组数，如连接同一管路中的一个或多个换热设备可看作一个或一组换热末端，如图1中示出包含2个风盘的一个(组)换热末端，本申请对此不作限制，可根据实际需要而选择合适的换热末端以及相应的数量。值得注意的是，在以下说明中，以风盘作为换热末端30的例子进行说明，但本申请并不限于此。
也就是说，本申请实施例的换热系统可包括一个或多个第一热源，以及一个或多个换热末端，如图1示出了换热系统包括一个第一热源和一个换热末端的情况，此外，换热系统还可包括1个第一热源和2个换热末端，或者换热系统还可包括2个第一热源和1个换热末端，或者换热系统还可包括2个第一热源和2个换热末端等，在此不一一列举。
在本申请实施例中，第三管路43的连接方式可以有多种，例如，图1中示出第三管路43可设置于胆10的内部，但本申请不限于此，第三管路43也可设置于胆10的外部，或者，第三管路43可以包括设置于胆10的内部的部分管路以及设置于胆10的外部的部分管路，换言之，第三管路43可以为2个，分别设置于胆10的内部和外部，此外，第三管路43也可以多于两个，本申请对此不作限制，以下进行详细说明。
在一些实施例中，当第三管路43设置于胆10的内部的情况下，如图1所示，第三管路43的两端可分别连接第一入口11和第一出口12，但本申请不限于此，例如，还可以为，第三管路的一端连接第一入口11，另一端靠近第一出口12，或者，第三管路的 一端连接第一出口12，另一端靠近第一入口11，或者，第三管路的一端靠近第一入口11，另一端靠近第一出口12，第三管路可采用各种方式固定于胆10的内部，本申请对此不作限制。由此，能够通过第三管路43将第一管路41中的流体引导至第二管路42，从而实现快速制冷或制热。
在本申请实施例中，第三管路43设置于胆10的上部，也就是说，第三管路43在胆10内处于靠上部的位置，由此，胆10内第三管路43周围的水温较高，在速热时，能够抑制通过第三管路43引导至换热末端30的水温的降低，但本申请不限于此，第三管路43可设置于胆10内的其它位置。
在本申请实施例中，当第三管路43设置于胆10的内部的情况下，第三管路43的两端均为开口，从而能够通过第三管路43的两端连接或靠近第一入口11、第一出口12，而将第一管路41中的流体引导至第二管路42中。
在一些实施例中，第三管路43的周壁可设置有开孔，由此，第三管路43中的流体可通过开孔而流入胆10内，胆10内的流体也可流入第三管路43中，从而在实现快速制热或制冷的同时能够满足换热末端的不同流量需求，并确保一次系统和二次系统之间的压力平衡。
在本申请实施例中，对于第三管路43的周壁的开口位置、数量、孔径均不作限制，例如，开口的数量可以为一个或多个，多个开口可沿第三管路43的周向等间隔或不等间隔地设置于第三管路43的壁部，但本申请不限于此，只要通过设置于周壁的开口以供流体在第三管路43和胆10内之间流动，从而能够满足换热终端侧的流量需求即可。
在一些实施例中，第三管路43的靠近第一入口11侧的开孔密度不大于靠近第一出口12侧的开孔密度，也就是说，在靠近第一入口11和靠近第一出口12的相同的管路面积上，近第一出口侧的开孔总面积大，由此，一方面，将靠近第一出口12侧的开孔密度设置得较大，能够使靠近第一出口侧的第三管路43从胆10中引入更多流体，满足换热末端的流量需求，并且有利于使第三管路43内的水流入第二管路42中，另一方面，将靠近第一入口11侧的开孔密度设置得比较小，能够防止用于速热/速冷的流体过多的进入胆10而影响换热末端的速热/速冷效果。但本申请不限于此，第三管路43的靠近第一入口侧的开孔密度也可以大于靠近第一出口侧的开口密度。由此，便于生产以及安装。
在本申请实施例中，图1示出设置于胆10的内部的第三管路43为中空的柱状，由此，便于第三管路43的生产以及能够容易地将第三管路43组装到胆10内，但本申请不限于此，例如，第三管路43还可以为弧状或弯折形状，在第三管路43内部和胆内之 间的压力差较大时，能够增大第三管路43和胆10内之间的流体的流动的流量，满足换热末端的流量需求，更好地平衡一次系统和二次系统之间的压力。此外，图1中示出胆10的第一入口11和第一出口12分别设置于胆10的两侧，即径向上相对的位置，但本申请不限于此，例如第一入口11和第一出口12还可以设置于胆10的同一侧，由此，通过利用例如弧状的第三管路43，使第三管路43的弧状部分位于胆10的中心部分，在第三管路43内部和胆内之间的压力差较大时，能够确保第三管路43和胆10内之间的引流，满足换热末端的流量需求，更好地平衡一次系统和二次系统之间的压力。但本申请不限于此，第一入口11和第一出口12还可以设置于胆的其它位置。
在一些实施例中，第三管路43可位于胆10的外部，例如，第三管路43的一端可连接第一管路41，第三管路43的另一端可连接第二管路42，或者第三管路43的一端可连接第一管路41，第三管路43的另一端可连接换热末端30。由此，第三管路43的安装更为简单，且同样可以达到快速制热/制冷的效果。
在一些实施例中，第一入口11和第一出口12可以为同一开孔，如图2所示，第一入口11和第一出口12为同一开孔O，第一管路41和第二管路42具有相同的第一部分管路412，第二管路42包括第一部分管路412和第三管路43，换言之，第二管路42不包括第一部分管路412的部分可称为第三管路43，第三管路43将第一管路41中的至少部分流体引导至换热末端30。由此，可减少胆的开口数量，以简单的方式形成第三管路43。
在图2所示的换热系统中，第一管路41中的高温流体或低温流体可不和胆10内的水混合而直接供应换热末端30，能够实现快速制热或快速制冷，同时，当第一管路41中的水流量大于换热末端30所需水流量时，第一管路41中过量的水可以通过第一部分管路412流入胆10内，当第一管路41中的水流量小于换热末端30所需水流量时，胆10内的水还可以流入第三管路43中作为补充流量，从而实现一次系统和二次系统之间的压力耦合，值得说明的是，在胆10内的水流入第三管路43中作为补充流量的情况下，虽然供应给换热末端30的水中混合了胆10内的水，但和第一管路41中的水流入胆10之后再从胆向换热末端供应水的情况相比，第一管路41中的水能够完全流入第三管路43中，由此，图2所示换热系统仍然能够实现更快速的制热或制冷效果。
在图1和图2所示系统中，示出了换热系统包括1个第一热源和1个换热末端的情况，以下对于换热系统包括其它数量的第一热源和换热末端的情况进行举例说明。

以上对于第一热源的数量为1个或2个的情况进行了示例性说明，但本申请不限于此，第一热源20的数量还可以为其它数值，本申请对此不作限制，可根据实际需要(如换热系统中的功率等)而选择合适数量的第一热源20，此外，图4中示出了2个第一热源20(20-1、20-2)并联的连接方式，但本申请不下于此，2个或多于2个的第一热源20还可以串联，可根据实际需要(如换热系统中的功率等)而确定多个第一热源20的合适的连接方式。
在一个或多个实施例中，如图1所示，换热末端30的出口32通过第一回流管路51和胆10的第三入口13连接，第一热源20的入口22通过第二回流管路52和胆10的第二出口14连接。由此，在回流管路中，第一热源20和换热末端30均连接胆10，能够通过胆10实现一次系统和二次系统之间的耦合功能。但不限于此，例如换热末端30的出口32可直接与第一热源20的入口22连接，由此，回流水能够直接回流至第一热源20中。
在一个或多个实施例中，如图1所示，换热系统还具有第三回流管路53，第三回流管路53将第一回流管路51中的至少部分流体引导至第二回流管路52或第一热源10，由此，能够将回收的流体直接流入第一热源以再次利用，能够提高能量利用效率。例如，当第一回收管路中的回收流体的温度为低温流体时，可将其直接流入第一热源，以作为用于提供制冷功能的冷媒，当第一回收管路中的回收流体的温度为高温流体时，可将其直接流入第一热源，以作为用于实现制热功能的热媒，从而实现高效的能量回收利用。

以上对于换热系统具有第一热源的情况进行了说明，第一热源可以为以下设备中的任意一者或组合：燃气热水装置、电热水装置、热泵和太阳能热水器，但本申请不限于此，换热系统还可包括第二热源，第二热源可以为以下设备中的任意一者或组合：燃气热水装置、电热水装置、热泵和太阳能热水器。以下进行详细说明。
在一个或一些实施例中，如图6所示，换热系统还包括第二热源60和第五管路45，第二热源60的出口61通过第四管路44和胆10的第二入口15连接，第五管路45连接第四管路44和以下任意一者或组合：第一管路41、第二管路42、第三管路43、换热末端30，也就是说，第五管路45的一端连接第四管路44，另一端连接第一管路41、第二管路42、第三管路43、换热末端30这四者中的任意一者或组合。
由此，通过第五管路45连接第四管路44和以下任意一者或组合：第一管路41、第二管路42、第三管路43和换热末端30，第二热源60中的热媒或冷媒也可供应至换热 末端30，能够实现快速制热或制冷，同时，第一热源、第二热源、换热末端均连接胆，能够通过胆实现一次系统和二次系统之间的耦合功能。
在本申请实施例中，换热系统包括第二热源60的情况下，换热系统中关于第一热源20、胆10以及换热末端30之间的连接方式可参见上述的相关说明，在此不再重复，以下举例说明第二热源60及相关管路在换热系统中的设置方式。
在一个或多个实施例中，如图6所示，胆10的第二入口15和胆的第一入口11、胆的第一出口12为不同开口，第五管路45的一端连接第四管路44，第五管路45的另一端连接第一管路41。由此，第四管路44中的流体可依次流经第五管路45、第一管路41和第三管路43，从而供应至换热末端30，从而用于实现快速制热或制冷。
在本申请实施例中，如图6所示，第四管路44和/或第五管路45中可设置有第一流量控制装置81，其中，第一流量控制装置81可以为包括三通阀、电动阀、二通阀中的任意一者。
由此，通过第一流量控制装置81，能够控制流体在第一管路41和第五管路45中的流动，获得更好的快速制热或制冷效果，同时，当第一流量控制装置81断开时，流体可以经第四管路44流入胆，当第一流量控制装置81连通时，流体可以流经第五管路45，从而更直接地被供应至换热末端30。
例如，在本申请实施例中，第一热源20和第二热源60可以为相同热源设备或不同热源设备，当第一热源20和第二热源60为不同热源设备时，第一热源20和第二热源60的功能可能不完全相同，例如第一热源20为燃气热水装置或电热水装置，如壁挂炉，其可以提供制热功能以及提供生活用水，第二热源60可以为热泵，其可以提供制冷或制热功能，但热泵的高温热水的最高温度会低于壁挂炉的高温热水的最高温度。在此情况下，当第一热源20为壁挂炉，第二热源60为热泵时，通过第一流量控制装置81的控制，能够获得更好的快速制热或制冷效果。
例如，当换热末端需要实现制热时，可控制第一流量控制装置81而防止第五管路45中的流体流入第一管路41中，作为第一热源20的壁挂炉的高温热水依次经过第一管路41、第三管路43，从而供应至换热末端30，由于壁挂炉的高温热水的温度高于热泵的高温热水的温度，通过第一流量控制装置81的控制，能够避免热泵中的热水混入壁挂炉产生的高温热水而降低供应至换热末端30的高温热水的温度，从而实现换热末端的快速制热。
在一些实施例中，当换热末端30需要的热水流量大于壁挂炉的高温热水流量时， 第一流量控制装置81可打开，从而将壁挂炉产生的高温热水和热泵产生的高温热水一起供应至换热末端30，能够尽量减少或避免将胆10内温度较低的水作为补充流量而供应至换热末端，从而既能够满足换热末端的大流量需求又满足了换热末端的快速制热。
在一些实施例中，当换热末端30存在制冷需求时，作为第一热源的壁挂炉不向第一管路41中供应热水，第一流量控制装置81可打开，热泵产生的低温冷水可依次流经第四管路44、第五管路45、第一管路41以及第三管路43，从而供应至换热末端30，实现换热末端30的快速制冷。
在本申请实施例中，第一流量控制装置81在第四管路44和/或第五管路45中的设置位置可以为多处，例如，如图6所示，第一流量控制装置81可设置于第五管路45的两端之间的位置，第一流量控制装置81可以为例如电动阀或二通阀，但不限于此，例如，第一流量控制装置81还可设置于第五管路45和第四管路44相连接的位置，第一流量控制装置81可以为例如三通阀，此外，第一流量控制装置81也可设置于第五管路45和第一管路41相连接的位置，第一流量控制装置81可以为例如三通阀，此外，第一流量控制装置81也可设置于第四管路44，如第一流量控制装置81可位于第五管路45和第四管路44相连接的位置与第二入口15之间，第一流量控制装置81可以为例如电动阀或二通阀。
图6示出了第五管路45连接第四管路44和第一管路41的一个示例，但本申请不限于此，如图7所示，当第三管路43包括设置于胆10内的部分管路和设置于胆10外的部分管路的情况下，例如第三管路43的两端均分别连接第一管路41和第二管路42，但不限于此，如第三管路43的位于胆10外的部分管路的两端可分别连接第一管路41和换热末端30，在此情况下，胆10的第二入口15和胆10的第一入口11可以为同一开孔m，第四管路44和第一管路41具有相同的第二部分管路414，第二部分管路414连接第四管路44和第三管路43，因此，第二部分管路414即为第五管路45。
在图7所示换热系统中，第一热源20的热媒或冷媒可依次流经第一管路41、第三管路43、第二管路42而供应至换热终端30，实现快速制热或制冷，第二热源60的热媒或冷媒也可通过第四管路44、第三管路43而供应至换热终端30，实现快速制热或制冷。当换热末端存在较大流量需求时，第一热源20和第二热源60中的热媒或冷媒可一起供应至换热末端，从而既能够满足换热末端的大流量需求又满足了换热末端的快速制热。
在本申请实施例中，如图7所示，第一管路41中还可设置第四流量控制装置84， 第四流量控制装置84可以为单向阀，第四流量控制装置84可设置于第五管路45以及设置于胆10的外部的第三管路43和第一管路41连接的位置，由此，通过第四流量控制装置84能够防止第二热源60的出水流入第一热源20。
图8示出了第五管路45连接第四管路44和第一管路41的另一个示例，如图8所示，胆的第一入口和第一出口为同一开孔，即第一管路41和第二管路42连接胆10的同一开孔，第一管路41和第二管路42具有相同的第一部分管路412，第二管42路包括第一部分管路412和第三管路43，在此情况下，第五管路45也可与第一管路41连接，如图8所示，胆的第二入口、第一入口和第一出口为同一开孔，第四管路44连接第二热源60和胆10，第四管路44和第一管路部分412具有相同的第三部分管路445，换言之，第四管路44和第一管路41或第二管路42具有相同的第三部分管路445，第四管路44包括第三部分管路445和第五管路45。由此，第四管路44中的流体可依次流经第五管路45、第二管路42，从而供应至换热末端30，从而用于实现快速制热或制冷。
在图8所示换热系统中，第一热源20的热媒或冷媒可依次流经第一管路41、第三管路43而供应至换热终端30，实现快速制热或制冷，第二热源60的热媒或冷媒也可通过第五管路45、第二管路42而供应至换热终端30，实现快速制热或制冷。当换热末端存在较大流量需求时，第一热源20和第二热源60中的热媒或冷媒可一起供应至换热末端，从而既能够满足换热末端的大流量需求又满足了换热末端的快速制热或制冷。
在本申请实施例中，如图8所示，第二管路42中还可设置第五流量控制装置85，第五流量控制装置85可以为单向阀，第五流量控制装置85可设置于第一部分管路412的非第三部分管路445的部分，由此，通过第五流量控制装置85能够防止第一热源20的出水流入第二热源60。
图9示出了第五管路45连接第四管路44和第二管路42的情况，如图9所示，第三管路43设置于胆10的内部，第三管路43的两端分别连接第一管路41和第二管路42，胆10的第二入口15和胆的第一入口11、第一出口12为不同开口，在此情况下，第五管路45的一端可连接第四管路44，第五管路45的另一端可连接第二管路42。
在图9所示换热系统中，第一热源20的热媒或冷媒可依次流经第一管路41、第三管路43、第二管路42而供应至换热终端30，实现快速制热或制冷，第二热源60的热媒或冷媒也可通过第四管路44、第五管路45、第二管路42而供应至换热终端30，实现快速制热或制冷。当换热末端30存在较大流量需求时，第一热源20和第二热源60中的热媒或冷媒可一起供应至换热末端30，从而既能够满足换热末端的大流量需求又满足 了换热末端的快速制热或制冷。
在本申请实施例中，如图9所示，第二管路42中还可设置第二流量控制装置82，第二流量控制装置82可以为单向阀，第二流量控制装置82设置于第二管路42和第五管路45相连接的位置和第一出口12之间，由此，通过第二流量控制装置82能够防止第二热源60的出水流入第一热源20。
在一个或多个实施例中，如图6所示，换热末端30的出口32通过第一回流管路51和胆10的第三入口13连接，第一热源20的入口22通过第二回流管路52和胆10的第二出口14连接，第二热源60的入口62通过第四回流管路54和胆10的第三出口16连接。由此，在回流管路中，第一热源20、第二热源60和换热末端30均连接胆10，能够通过胆10实现一次系统和二次系统之间的耦合功能。
但本申请不限于此，例如，换热末端30的出口32可直接与第一热源20的入口22连接，第二热源60的入口62通过第四回流管路54和胆10的第三出口16连接；或者，换热末端30的出口32通过第一回流管路52和胆10的第三入口13连接，第一热源20的入口22通过第二回流管路52和胆10的第二出口14连接，第二热源60的入口62直接与换热末端30连接；或者，换热末端30的出口32直接与第一热源20的入口22连接，第二热源60的入口62直接与换热末端30连接。可根据实际需要而选择合适的回流管路连接方式。
在一个或多个实施例中，换热系统还具有第三回流管路53(见图6)和/或第五回流管路(图中未示出)，第三回流管路将第一回流管路51中的至少部分流体引导至第二回流管路52或第一热源20，第五回流管路将第一回流管路51中的至少部分流体引导至第四回流管路54或第二热源60。由此，能够将回收的流体直接流入第一热源和/或第二热源以再次利用，能够提高能量利用效率。例如，当第一回收管路中的回收流体的温度为低温流体时，可将其直接流入第一热源和/或第二热源，以作为用于提供制冷功能的冷媒，当第一回收管路中的回收流体的温度为高温流体时，可将其直接流入第一热源和/或第二热源，以作为用于实现制热功能的热媒，从而实现高效的能量回收和利用。

第二方面的实施例
本申请第二方面的实施例提供一种胆，用于换热系统，关于换热系统的说明，请见上述第一方面的实施例，此处省略说明。
图10是本申请实施例的胆的一个示意图。
如图10所示，胆10包括第一入口11和第一出口12，第一入口11用于通过第一管路连接第一热源，第一出口12用于通过第二管路连接换热末端，胆10还包括第三管路43，第三管路43用于将第一管路中的至少部分流体引导至第二管路或换热末端。
关于第一管路、第一热源、第二管路、换热末端，请见上述第一方面的实施例中关于第一管路41、第一热源20、第二管路42、换热末端30的说明，其内容合并于此。
由此，第三管路43用于将第一管路中的流体引导至第二管路或换热末端，第一热源中的高温流体或低温流体可直接供应换热末端，从而实现快速制热或制冷，同时，第一热源、换热末端均连接胆，能够通过胆实现一次系统和二次系统之间的耦合功能。
在一个或多个实施例中，如图10所示，第三管路43设置于胆10的内部，但本申请不限于此，第三管路43也可位于胆10的外部，第三管路43的一端连接第一入口11，第三管路43的另一端连接第一出口12。本申请对此不作限制，可根据实际需要而选择合适的设置方式。

在一个或多个实施例中，第三管路43的周壁可设置有开孔，由此，第三管路43中的流体可通过开孔而流入胆10内，胆10内的流体也可流入第三管路43中，从而在实现快速制热或制冷的同时能够满足换热末端的不同流量需求，并确保一次系统和二次系统之间的压力平衡。
在一个或多个实施例中，第三管路43的靠近第一入口11侧的开孔密度不大于靠近第一出口12侧的开孔密度，也就是说，在靠近第一入口11和靠近第一出口12的相同的管路面积上，近第一出口侧的开孔总面积大，由此，一方面，将靠近第一出口12侧的开孔密度设置得较大，能够使靠近第一出口侧的第三管路43从胆10中引入更多流体，满足换热末端的流量需求，并且有利于使第三管路43内的水流入第二管路中，另一方面，将靠近第一入口11侧的开孔密度设置得比较小，能够防止用于速热/速冷的流体过多的进入胆10而影响换热末端的速热/速冷效果。但本申请不限于此，第三管路43的靠近第一入口侧的开孔密度也可以大于靠近第一出口侧的开口密度。由此，便于生产以及安装所述第三管路的靠所述第一入口侧的开孔密度不大于靠所述第一出口侧的开孔密度。
在一个或多个实施例中，如图10所示，第三管路43设置于胆10的上部，也就是说，第三管路43在胆10内处于靠上部的位置，由此，胆10内第三管路43周围的水温较高，在速热时，能够抑制通过第三管路43引导至换热末端的水温的降低，但本申请不限于此，第三管路43可设置于胆10内的其它位置。本申请对此不作限制，可根据实际需要将第三管路43设置在但10内合适的位置。
在一个或多个实施例中，如图11所示，胆10还包括第二入口15和第五管路(图中未示出)，第二入口15用于通过第四管路连接第二热源，第五管路连接第四管路和以下任意一者或组合：第一管路、第二管路、第三管路、换热末端。

关于第二热源、第四管路、第五热源，请见上述第一方面的实施例中关于第二热源60、第四管路44、第五管路45的说明，其内容合并于此。
在一个或多个实施例中，第二入口15和第一入口11是同一开孔，由此，能够减少胆10的开孔数量，便于胆10的生产和安装，在此情况下，第四管路和第一管路具有相 同的第二部分管路，由此，第四管路中的流体可依次流经第一管路和第三管路，从而供应至换热末端，从而用于实现快速制热或制冷。具体可见上述第一方面实施例中的相关说明，其内容合并于此。
但本申请不限于此，例如，如图11所示，在一个或多个实施例中，第二入口15和第一入口11为不同开孔，第五管路的一端连接第四管路，第五管路的另一端连接第一管路。由此，第四管路中的流体可依次流经第五管路、第一管路和第三管路，从而供应至换热末端，从而用于实现快速制热或制冷。
在一个或多个实施例中，第四管路和/或第五管路中设置有第一流量控制装置。由此，通过第一流量控制装置81，能够控制流体在第一管路41和第五管路45中的流动，获得更好的快速制热或制冷效果。第一流量控制装置81可以为包括三通阀、电动阀、二通阀中的任意一者。具体可见上述第一方面实施例中的相关说明，其内容合并于此。
在一个或多个实施例中，第一管路、第二管路、第四管路、第五管路和第一流量控制装置均设置在同一壳体内。例如，第一管路、第二管路、第四管路、第五管路、第一流量控制装置和胆10连接之后，并外部设置有一壳体，或者，第一管路、第二管路、第四管路、第五管路和第一流量控制装置可以作为模块化产品生产并且其外周为一壳体，之后改模块化产品和胆10连接组装。本申请对此不作限制，可根据实际需要而进行选择。
值得注意的是，以上仅为胆10、第三管路43的示例性说明，关于胆10、第三管路43以及相关的部件，还可见上述第一方面的实施例中的说明，其内容合并于此。
以上结合具体的实施方式对本申请进行了描述，但本领域技术人员应该清楚，这些描述都是示例性的，并不是对本申请保护范围的限制，且本申请说明书中的上述各个实施方式之间相似部分相互参照即可，每个实施方式重点说明的都是与其它实施方式不同之处。本领域技术人员可以根据本申请的精神和原理对本申请做出各种变型和修改，这些变型和修改也在本申请的范围内。
