发明内容
为了克服现有技术的上述缺陷，本发明实施例所要解决的技术问题是提供了一种联供系统及其控制器和控制方法，其能够确保联供系统能够智能地供给热水负荷和采暖负荷。
为了实现上述目的，本发明所采用的技术方案内容具体如下：
本发明公开了一种联供系统的控制方法，所述联供系统包括第一热源，所述联供系统的控制方法包括以下步骤：
控制第一热源供给热水负荷直至所述热水负荷被所述第一热源满足；
当所述热水负荷被所述第一热源满足，且存在对采暖负荷的需求时，改变所述第一热源的运行状态，在使所述热水负荷被满足的基础上，供给所述采暖负荷；
或者，
控制第一热源供给采暖负荷直至所述采暖负荷被所述第一热源满足；
当所述采暖负荷被所述第一热源满足，且存在对热水负荷的需求时，改变所述第一热源的运行状态，在使所述采暖负荷被满足的基础上，供给所述热水负荷。
本发明还公开了一种联供系统的控制器，所述联供系统的控制器执行如上述的联供系统的控制方法。
本发明还公开了一种联供系统，所述联供系统包括：如上述所述的联供系统的控制器；第一热源；分别能与所述第一热源连通的第一流道和第二流道；

与现有技术相比，本发明的有益效果在于：
通过上述联供系统的控制方法能够确保联供系统能够智能地供给热水负荷和采暖负荷，具体而言，当热水负荷和采暖负荷中的一个优先被第一热源满足之后或者第一热源被配置为优先满足热水负荷和采暖负荷中的一个时，热水负荷和采暖负荷中的另一个再出现或同时出现热水负荷和采暖负荷中的另一个时，若第一热源具有富裕的输出负荷，在能够确保在先的负荷或被配置为优先级较高的负荷持续被满足的前提下，改变自身运行状态以将富裕的输出负荷供给再出现的热水负荷和采暖负荷中的另一个或被配置为优先级低的负荷。这样就能够避免因另一个负荷的出现而造成第一热源对在先的负荷供给的不足，或者，两个负荷同时出现而造成第一热源对被配制为优先级较高的负荷供给的不足，与此同时，又能够在一定程度上使得第一热源能够兼顾到在后的负荷或被配制为优先级较低的负荷，使得第一热源被最大化利用。

第一末端17用于供给热水负荷，其可以为能够输出热水以供用户使用的一类装置。具体而言，第一末端17可以是水的加热装置，其能对水进行加热并将加热后的水供给用户使用，也可以是热水的输出装置，例如，生活中使用的龙头、花洒等装置，能够将第一热源1通过第一流道2输出的如热水一类的热流体直接输出供给用户使用。第二末端8则用于供给采暖负荷。第二末端8可以为供热采暖的一类装置，例如，第二末端8可以至少包括以下之一：风盘、地暖、暖气片、墙内换热设备等等，在本申请中并不对其做具体的限定。
作为可行的，图2为本发明实施例中联供系统在第二种实施方式下的结构示意图，如图2所示，第一热源1可以包括多个第一子热源11，多个第一子热源11并联连接。为了实现多个第一子热源11均能够独立的控制流体分流至第一流道2和第二流道3的流量，第一流量控制装置4可以包括多个第一子流量控制装置41，第一流道2包括多个第一子流道21，第二流道3包括多个第二子流道31。第一子流量控制装置41用于控制相对应的第一子热源11的流体分流至相对应的第一子流道21和第二子流道31的流量。例如，第一子流道21和第二子流道31能与自己相对应的第一子热源11相连通。第一子流量控制装置41可以设置在自己相对应的第一子流道21和第二子流道31的连通处， 亦或者，对于一个第一子热源11，相对应的第一子流量控制装置41为两个，其分别设置在相对应的第一子流道21和第二子流道31上。多个第一子流道21的下游可以合并为一个流道并用于为第一末端17供应热量，同理，多个第二子流道31的下游可以合并为一个流道并用于为第二末端8供应热量。
进一步的，当第一末端17和第二末端8都需要热量，但是所需热量的温度不同时，通过并联的多个第一子热源11可以将第一热源1中的部分第一子热源11与另外一部分第一子热源11分别产生不同温度的热量，从而分别供给至第一末端17和第二末端8。例如，第一末端17供给的热水需要达到高温，如80度以上，但是第二末端8供给采暖的热水只需要达到65度左右，此时，就可以将第一热源1中的部分第一子热源11生成80度以上的热流体，而另外一部分第一子热源11生成65度左右的热流体，从而分别供给第一末端17和第二末端8，以满足两者完全不同的温度需求。
又例如，在天气炎热的时候，当第一末端17供给的为热水负荷，第二末端8供给的采暖负荷为冷负荷时，此时，就可以将第一热源1中的部分第一子热源11处于制热运行状态以生成热流体，通过第一子流量控制装置41向第一末端17输送，从而满足第一末端17的热水负荷，而另外一部分第一子热源11则处于制冷运行状态以生成冷流体，通过第一子流量控制装置41向第二末端8输送，从而满足第二末端8的冷负荷。通过并联的多个第一子热源11和第一子流量控制装置41的配合可以将不同第一子热源11生成的热流体和冷流体分别输送给第一末端17和第二末端8，以满足完全不同类型的热量需求。
图3为本发明实施例中联供系统在第三种实施方式下的结构示意图，如图3所示，本申请实施例中的联供系统可以包括：第二热源5；分别能与第二热源5连通的第三流道6和第四流道7。第二流量控制装置19，用于控制第二热源5的流体分流至第三流道6和第四流道7的流量，第三流道6和第四流道7分别用于为第一末端17和第二末端8提供热量。
第二热源5可以是能够提供热量的任意一类装置，其可以将提供的热量以流体携带的形式通过第三流道6供给至第一末端17和/或通过第四流道7供给至第二末端8。例如，第二热源5可以包括热泵装置或燃气热水器或电热水器等等，在本申请中并不对其做具体的限定，也可以是上述一类装置的任意组合。第二流量控制装置19控制第二热源5的流体分流至第三流道6和第四流道7的流量，第二流道3控制装置的功能、具体安装的位置等可以与第一流道2控制装置相类似，在此不再赘述。通过第二流量控制装 置19可以对第二热源5提供的热流体进行合理的分配，使其根据第一末端17和第二末端8具体不同的需求，供给相对应流量的热流体，从而满足第一末端17和第二末端8变化的需求。
由于第一热源1能够分别给第一末端17和第二末端8供给热流体或冷流体，第二热源5也能够分别给第一末端17和第二末端8供给热流体或冷流体，因此，通过第一流量控制装置4和第二流量控制装置19的控制，可以使得第一热源1产生的流体以合理的分流供给至第一末端17和第二末端8，同时，第二热源5产生的流体也可以以合理的分流供给至第一末端17和第二末端8，这样使得第一末端17和第二末端8需要的不同负荷可以合理的选择性的被满足。另外，通过第一热源1和第二热源5的配合在某些时刻可以更大范围的满足第一末端17或第二末端8需要的负荷，使得整个联供系统的兼顾性更佳。
作为可行的，第二热源5也可以包括多个第二子热源，多个第二子热源并联连接。第二流量控制装置19包括多个第二子流量控制装置，第三流道6包括多个第三子流道，第四流道7包括多个第四子流道，第二子流量控制装置用于控制相对应的第二子热源的流体分流至相对应的第三子流道和第四子流道的流量。同理，通过并联的多个第二子热源和第二子流量控制装置的配合可以将第一热源1中的部分第一子热源11与另外一部分第一子热源11分别产生不同温度的热量，从而分别供给至第一末端17和第二末端8；也可以将不同第二子热源生成的热流体和冷流体分别输送给第一末端17和第二末端8，以满足完全不同类型的热量需求。
作为可行的，在一些实施方式中，第二子流量控制装置可以只需要控制相对应的第二子热源产生的流体完全流入第三子流道或者第四子流道，以供给后出现的采暖负荷或热水负荷，在这些情况下，第二子流量控制装置可以包括分别设置在第三子流道和第四子流道上的开关阀或设置在第三子流道和第四子流道连通处的三通阀。
在一种可行的实施方式中，如图1至图3所示，第二流道3和第四流道7的出口用于与第二末端8相连通，从而使得第一热源1和第二热源5生成的流体能够直接通入第二末端8中，以提供相应的热量。第一流道2和第三流道6的出口用于与第一末端17相连通，从而使得第一热源1和第二热源5生成的流体能够直接通入第一末端17中，以提供相应的热量。
在一种可行的实施方式中，图4为本发明实施例中联供系统在第四种实施方式下的结构示意图，如图4所示，联供系统可以包括：具有第一换热流道和第二换热流道的第 一换热装置9。第二流道3可以包括第二换热流道，第四流道7包括第一换热流道，第二流道3用于与第二末端8相连通。第一热源1生成的流体在流经第一换热装置9的第二换热流道以后，再输送至第二末端8中，而第二热源5生成的流体则流经第一换热装置9的第一换热流道，在此期间能够与第二换热流道中流经的第一热源1生成的流体进行换热，从而进一步提高或降低第一热源1生成的流体的温度，具体可以根据第二末端8的需求所确定。
在上述实施方式中，当第一热源1运行产生的流体的温度不足够高或者不足够低时，可以通过第二热源5运行产生的流体去进一步升高或降低第一热源1运行产生的流体的温度，最终使得输入至第二末端8的流体的温度达到要求。例如，当第一热源1为热泵时，在天气温度较低时，热泵制取高温流体的性能偏低，其不易产生温度较高的热流体以满足第二末端8的需求，此时，第二热源5可以是燃气热水器或电热水器等，其依然能够产生温度较高的热流体，通过第二热源5产生的热流体进一步给第一热源1产生的温度偏低一些的热流体进行加热，以最终使得输入至第二末端8的流体的温度达到要求。由于热泵在较多运行工况下(比如制取温度偏低的流体时)具有较高的能耗比，其与燃气热水器或电热水器等一类的第二热源5配合使用在满足第二末端8需求的同时，也兼顾了联供系统的能耗比和经济效益。同理，在天气温度较高时，在热泵制取冷流体的性能偏低，其不易产生温度较低的冷流体以满足第二末端8的需求，此时，第二热源5可以是热泵，其可以产生流量较小的、但温度较低的冷流体，通过第二热源5产生的冷流体进一步给第一热源1产生的温度偏高一些的、但流量偏大的冷流体进行进一步降低，以最终使得输入至第二末端8的流体的温度达到要求。
为了进一步提高第一热源1生成的流体在流经第一换热装置9的第二换热流道与第二热源5生成的、流经第一换热装置9的第一换热流道的流体之间的换热效率，第一换热装置9可以采用板式换热器。另外，板式换热器还可以满足换热流体的高流量。
在一种可行的实施方式中，联供系统可以包括具有第三换热流道的第二换热装置10，第一流道2用于与第三换热流道相连通。在该方式中，第一热源1生成的热流体可以输送至第二换热装置10的第三换热流道中以与第二换热装置10中的水进行换热，从而达到对第二换热装置10中的水的加热目的，第二换热装置10中加热后的水则可以输出供给用户使用。同理，联供系统可以包括具有第四换热流道的第三换热装置12，第三流道6用于与第四换热流道相连通。第二热源5生成的热流体可以输送至第三换热装置12的第四换热流道中以与第三换热装置12中的水进行换热，从而达到对第三换热装置 12中的水的加热目的，第三换热装置12中加热后的水也可以输出供给用户使用。当然的，第二换热装置10和第三换热装置12的内部可以分别与水源23相连通，以补水。
在另一种可行的实施方式中，联供系统可以包括具有第三换热流道和第四换热流道的第二换热装置10；第一流道2用于与第三换热流道相连通；第三流道6用于与第三换热流道相连通。在该方式中，第一热源1生成的热流体通过第一流道2可以输送至第二换热装置10的第三换热流道中，以对第三换热装置12中的水进行换热。第二热源5生成的热流体通过第三流道6输送至第二换热装置10的第四换热流道中，以对第二换热装置10中的水进行换热。第一热源1和第二热源5能够同时对第二换热装置10中的水进行换热，从而能够进一步提高第二换热装置10中的水的加热速度，以减少用户的等待时间。
在又一种可行的实施方式中，如图4所示，联供系统可以包括具有第三换热流道的第二换热装置10和具有第四换热流道的第三换热装置12，第三换热装置12与第二换热装置10相连通；第一流道2用于与第三换热流道相连通；第三流道6用于与第四换热流道相连通。在该方式中，第一热源1生成的热流体可以输送至第二换热装置10的第三换热流道中以与第二换热装置10中的水进行换热，从而达到对第二换热装置10中的水的加热目的；第二热源5生成的热流体可以输送至第三换热装置12的第四换热流道中以与第三换热装置12中的水进行换热，从而达到对第三换热装置12中的水的加热目的。第三换热装置12与第二换热装置10相连通，从而使得两者中的水可以同时供给用户。另外，第一热源1与第二热源5分别独立的对第三换热装置12与第二换热装置10进行加热，因此，对两者中的水的加热程度和加热温度可以完全不同。当然的，第二换热装置10和第三换热装置12的内部可以与水源23相连通，以补水。
在上述实施方式中，进一步，如图4所示，第二换热装置10可以具有用于存储水的第一储水腔。第三换热装置12具有用于存储水的第二储水腔。第一储水腔与第二储水腔相连通，从而达到第三换热装置12与第二换热装置10相连通。第三换热流道能与第一储水腔中的存储水进行换热；第四换热流道能与第二储水腔中的存储水进行换热。第二换热装置10的与第一储水腔相连通的出水口能与第三换热装置12的与第二储水腔相连通的进水口相连通。第二换热装置10的与第一储水腔相连通的进水口用于与水源23相连通。第三换热装置12的与第二储水腔相连通的出水口用于供给热水。
在该结构中，水源23的水可以先进入至第二换热装置10的第一储水腔，通过第一热源1输送至第三换热流道的热流体进行初步加热至第一预设温度，当第三换热装置12 中的水向外输出供给用户使用后，第二换热装置10的第一储水腔中处于第一预设温度的水就能补充至第三换热装置12的第二储水腔中，之后，第二热源5输送至第四换热流道的热流体能对第三换热装置12中的水二次加热至更高的温度。通过上述加热方式，可以对第一热源1和第二热源5产生热流体的不同能力进行阶梯利用，以提高整个联供系统的能耗比。
例如，当第一热源1为热泵，第二热源5为燃气热水器或电热水器时，由于热泵制取温度偏低的热流体时，其能耗比较高，具有很高的性价比优势，但是其制取高温流体时，其能耗比就会大幅下降，不再具有较高的性价比，因此，可以先采用热泵对第二换热装置10的第一储水腔中刚补入的水进行初步加热至第一预设温度，之后再利用能够燃气热水器或电热水器等产生的热流体对流入至第三换热装置12中的水进行二次加热至更高的温度。
作为可行的，如图4所示，联供系统可以包括：分别能与第一热源1连通的第一回流流道13和第二回流流道14，第一回流流道13和第二回流流道14分别用于与第二换热装置10的第三换热流道和第二末端8的出口相连通。同理，联供系统可以包括：能与第二热源5连通的第四回流流道16，第四回流流道16能与第一换热流道的出口相连通。联供系统可以包括：能与第二热源5连通第三回流流道15，第三回流流道15能与第四换热流道的出口相连通。在上述方式中，通过回流流道可以将经过第三换热流道、第二末端8、第四换热流道、第一换热流道进行换热后的流体进行循环利用，同时换热后的流体依然具有少量的冷负荷或热负荷，其优于外界重新输入的流体，因此，可以减轻第一热源1和第二热源5的运行功率。
为了驱动流体在第一流道2和第二流道3中流动，相对应的，如图4所示，可以在第一流道2或第一回流流道13上设置第一循环泵20，可以在第二流道3或第二回流流道14上设置第二循环泵22。同样的，可以在第三流道6或第三回流流道15上设置第三循环泵，可以在第四流道7或第四回流流道16上设置第四循环泵。
在本申请的第一个实施例中，图5为本发明实施例中联供系统的控制方法在第一种实施方式下的步骤流程图，如图5所示，联供系统的控制方法可以包括以下步骤：
S101：控制第一热源1供给热水负荷直至热水负荷被第一热源1满足。
S102：当热水负荷被第一热源1满足，且存在对采暖负荷的需求时，改变第一热源1的运行状态，在使热水负荷被满足的基础上，供给采暖负荷。
在该实施例中，当先出现热水负荷时或者当联供系统的第一热源1用于优先满足热 水负荷时，例如，第一末端17需要热水负荷时，控制第一热源1向第一末端17供给热水负荷直至第一末端17的热水负荷被第一热源1满足。热水负荷可以指，能够输出热水以供用户使用的一类装置在对水进行加热时所需的负荷，例如，维持设定温度的热水供给下所需的负荷，或，维持设定加热速度下的给水加热所需的负荷。在该处，热水负荷被第一热源1满足可以具体包括下述情形：第一热源1通过热流体向第一末端17单位时间内输出的热功率满足第一末端17单位时间内的需求(例如，当第一末端17需求设定温度的热水时，所述第一热源1可以处于运行状态以保证设定温度的热水的供给)。当热水负荷被第一热源1满足，且存在对采暖负荷的需求时，例如，之后第二末端8出现对采暖负荷的需求，或者第二末端8出现对采暖负荷的需求与第一末端17对热水负荷的需求同时出现，此时，改变第一热源1的运行状态，从而使热水负荷在被继续满足的基础上，第一热源1还能够向第二末端8供给采暖负荷。采暖负荷可以指供热采暖一类装置在进行供热时所需的负荷，例如，维持设定温度的采暖流体供给下所需的负荷。
在本申请的第二个实施例中，图6为本发明实施例中联供系统的控制方法在第二种实施方式下的步骤流程图，如图6所示，联供系统的控制方法可以包括以下步骤：
S101：控制第一热源1供给采暖负荷直至采暖负荷被第一热源1满足。
S102：当采暖负荷被第一热源1满足，且存在对热水负荷的需求时，改变第一热源1的运行状态，在使采暖负荷被满足的基础上，供给热水负荷。
在该实施例中，当先出现采暖负荷时或者当联供系统的第一热源1用于优先满足采暖负荷时，例如，第二末端8需要采暖负荷时，控制第一热源1向第二末端8供给采暖负荷直至第二末端8的采暖负荷被第一热源1满足。在该处，采暖负荷被第一热源1满足具体可以包括以下情形：第一热源1通过热流体向第二末端8单位时间内输出的热功率达到第二末端8单位时间内的需求(例如，为保持室内的温度逐步上升至设定温度，使第一热源1可以处于运行状态以保证室内温度的上升)。当采暖负荷被第一热源1满足，且存在对热水负荷的需求时，例如，之后第一末端17出现对热水负荷的需求，或者第二末端8出现对采暖负荷的需求与第一末端17对热水负荷的需求同时出现，此时，改变第一热源1的运行状态，从而使采暖负荷在被继续满足的基础上，第一热源1还能够向第一末端17供给热水负荷。
通过上述联供系统的控制方法能够确保联供系统能够智能地供给热水负荷和采暖负荷，具体而言，当热水负荷和采暖负荷中的一个优先被第一热源1满足之后或者第一热源1被配置为优先满足热水负荷和采暖负荷中的一个时，热水负荷和采暖负荷中的另 一个再出现或同时出现时，若第一热源1具有富裕的输出负荷，在能够确保在先的负荷或被配置为优先级较高的负荷持续被满足的前提下，改变自身运行状态以将富裕的输出负荷供给再出现的热水负荷和采暖负荷中的另一个或被配置为优先级较低的负荷。这样就能够避免因另一个负荷的出现而造成第一热源1对在先的负荷供给的不足，或者，两个负荷同时出现而造成第一热源1对被配制为优先级较高的负荷供给的不足，与此同时，又能够在一定程度上使得第一热源1能够兼顾到在后的负荷或被配制为优先级较低的负荷，使得第一热源1被最大化利用。
在上述两种实施例中，在步骤S201中，当第一热源1为单一热源时，改变第一热源1的运行状态具体可以包括：提高第一热源1的运行功率，从而使得第一热源1提高的该部分功率供给后出现的热水负荷和采暖负荷中的其中一个。通过第一流量控制装置4可以将第一热源1提高的该部分功率相对应的流体分流至后出现的热水负荷和采暖负荷中的其中一个相对应的流道。
当第一热源1包括至少两个并联的第一子热源11时，改变第一热源1的运行状态具体可以包括：增加第一子热源11的运行数量；和/或，提高至少部分处于已经运行的第一子热源11的运行功率。
具体而言，若存在未运行的第一子热源11，则基于后出现的或相对第一热源1供给优先级较低的采暖负荷的需求或热水负荷的需求确定未运行的第一子热源11的开启数量，并使新开启的第一子热源11用于在使热水负荷被满足的基础上，供给采暖负荷，亦或者，在使采暖负荷被满足的基础上，供给热水负荷。当未运行的第一子热源11的功率能够满足后出现的采暖负荷的需求或热水负荷的需求时，可以通过上述方法满足后出现的或相对第一热源1供给优先级较低的采暖负荷的需求或热水负荷的需求，由于新开启的第一子热源11与之前已开启的第一子热源11是并联设置，因此，新开启的第一子热源11可以完全独立的运行，如此，新开启的第一子热源11的运行模式(例如可以包括制冷模式或制热模式等)或产出同一类型流体(热流体或冷流体)的温度可以与之前已开启的第一子热源11的不同，这样可以满足供给后出现的或者优先级较低的采暖负荷的需求或热水负荷的需求，该需求可以是与之前已开启的第一子热源11完全不同类型的热量需求，还可以是与之前已开启的第一子热源11完全不同的温度需求，进而实现不会影响到之前已经开启的第一子热源11的运行。通过上述步骤，可以满足第一末端17和第二末端8完全不同的温度需求或者不同类型的热量需求。
在该方式中，由于第一子流量控制装置41只需要控制相对应的第一子热源11产生 的流体完全流入第一子流道21或者第二子流道31，以供给后出现的或相对第一热源1供给优先级较低的采暖负荷或热水负荷，因此，第一子流量控制装置41可以包括分别设置在第一子流道21和第二子流道31上的开关阀或设置在第一子流道21和第二子流道31连通处的三通阀。
若所有第一子热源11均已开启，所有第一子热源11的总的运行功率未达到所有第一子热源11的总的最大额定功率，则可以提高所有第一子热源11中的至少部分的运行功率。通过上述方法可以在第一子热源11均已开启的前提下满足后出现的或相对第一热源1供给优先级较低的采暖负荷的需求或热水负荷的需求。通过第一子流量控制装置41可以将第一子热源11提高的该部分功率相对应的流体分流至后出现的热水负荷和采暖负荷中的其中一个相对应的流道，从而供给后出现的热水负荷和采暖负荷中的其中一个。
若存在未运行的第一子热源11，且未运行的第一子热源11的总的运行功率不能满足新存在的采暖负荷的需求或热水负荷的需求，已经处于运行状态的第一子热源11的总的运行功率未达到已经处于运行状态的第一子热源11的总的最大额定功率时，则可以开启未运行的第一子热源11并提高已经处于运行状态的第一子热源11中的至少部分的运行功率。当未运行的第一子热源11的功率不能够满足后出现的采暖负荷的需求或热水负荷的需求时，通过上述方法可以最大化的提高第一热源1向外的输出功率，从而最大可能的满足后出现的或相对第一热源1供给优先级较低的采暖负荷的需求或热水负荷的需求。在该步骤中，可以通过第一子流量控制装置41可以将第一子热源11提高的该部分功率相对应的流体分流至后出现的或相对第一热源1供给优先级较低的热水负荷和采暖负荷中的其中一个相对应的流道，将新开启的第一子热源11输出的流体输送至后出现的或相对第一热源1供给优先级较低的热水负荷和采暖负荷中的其中一个相对应的流道，最终供给后出现的或相对第一热源1供给优先级较低的热水负荷和采暖负荷中的其中一个。
在上述改变第一热源1的运行状态的步骤中，如果提高了已经处于运行状态的第一子热源11中的至少部分的运行功率，作为可选的，可以对所有已经处于运行状态的第一子热源11进行重新分配，以使其中部分供给热水负荷，部分供给采暖负荷。这样就可以避免一个第一子热源11输出的流体需要被第一子流量控制装置41分成两部分，分别供给热水负荷和采暖负荷。尤其当热水负荷和采暖负荷所需的流体的温度不同的，通过上述方法可以使得多个第一子热源11分成两部分，这两部分第一子热源11可以生成 不同温度的流体从而分别供给热水负荷和采暖负荷。
若第一热源1供给采暖负荷且采暖负荷为冷负荷、存在对热水负荷的需求时，改变第一热源1的运行状态可以包括：保持处于制冷工作状态的第一子热源11的数量不变，若存在未运行的第一子热源11，则将至少部分未运行的第一子热源11用于供给热水负荷。亦或者，若第一热源1供给热水负荷，存在对采暖负荷的需求，采暖负荷为冷负荷时，改变第一热源1的运行状态可以包括：保持处于制热工作状态的第一子热源11的数量不变，若存在未运行的第一子热源11，则将至少部分未运行的第一子热源11用于制冷以供给采暖负荷。
在上述情况下，第一热源1包括即能够产生冷负荷、又能够产生热负荷的一类装置，如并联的多个热泵。当热水负荷和采暖负荷所需的流体的冷热负荷不同时，通过上述方法可以使得多个第一子热源11分成两部分，这两部分第一子热源11以不同的运行模式运行，即制冷模式和制热模式，从而可以生成不同冷热性质的流体，以分别供给采暖负荷和热水负荷。
进一步的，联供系统的控制方法还可以包括以下步骤：
针对于第一个实施例中，在执行改变第一热源1的运行状态，在使热水负荷被满足的基础上，供给采暖负荷的步骤之后，若热水负荷增大，则减少供给采暖负荷的第一子热源11的运行数量，以用于供给增大的热水负荷。针对于第二个实施例中，在执行改变第一热源1的运行状态，在使采暖负荷被满足的基础上，供给热水负荷的步骤之后，若采暖负荷增大，则减少用于供给热水负荷的第一子热源11的运行数量，以用于供给增大的采暖负荷。通过上述步骤，在第一热源1同时供给热水负荷和采暖负荷以后，若优先被供给的或被配置为优先级较高的热水负荷或采暖负荷增大，则减少供给后出现的或被配置为优先级较低的采暖负荷或热水负荷相对应的第一子热源11的运行数量，以用于供给优先被供给的或被配置为优先级较高的热水负荷或采暖负荷。这样能够使得优先被供给的或被配置为优先级较高的热水负荷或采暖负荷始终被优先满足，不会出现优先被供给的或被配置为优先级较高的热水负荷或采暖负荷后续出现变化而造成无法被满足。
在第一个实施例的步骤S102中，当联供系统包括第二热源5，第二热源5也可以用于满足采暖负荷时，若第一热源1的运行比第二热源5的运行更具有优势时，则当热水负荷被第一热源1满足，且存在对采暖负荷的需求时，改变第一热源1的运行状态，在使热水负荷被满足的基础上，供给采暖负荷。同理，在第二个实施例的步骤S102中， 当联供系统包括第二热源5，第二热源5也可以用于满足热水负荷时，若第一热源1的运行比第二热源5的运行更具有优势时，则当采暖负荷被第一热源1满足，且存在对热水负荷的需求时，改变第一热源1的运行状态，在使采暖负荷被满足的基础上，供给热水负荷。该优势可以为能耗比优势或者为性价比优势。
通过上述方法步骤，当联供系统存在能够用于满足后出现的或相对第一热源1供给优先级较低的采暖负荷或热水负荷的第二热源5时，当存在后出现的或相对第一热源1供给优先级较低的采暖负荷或热水负荷时，优先采用更具有优势的第一热源1去供给后出现的或相对第一热源1供给优先级较低的采暖负荷或热水负荷。当优势为能耗比优势时，可以使得整个联供系统在运行过程中更加节能环保；当优势为性价比优势时，可以使得整个联供系统在运行过程中更加节约运行成本。
若在改变第一热源1的运行状态的步骤被执行后，后出现的或相对第一热源1供给优先级较低的采暖负荷或热水负荷无法被满足，则再运行第二热源5，从而进一步供给后出现的或相对第一热源1供给优先级较低的采暖负荷或热水负荷，进而尽最大可能使得后出现的或相对第一热源1供给优先级较低的采暖负荷或热水负荷被满足。
在第一个实施例的步骤S102中，在联供系统包括第二热源5，第二热源5也可以用于满足采暖负荷的前提下，当热水负荷被第一热源1满足，且存在对采暖负荷的需求时，可以改变第一热源1的运行状态并运行第二热源5，在使热水负荷被满足的基础上，供给采暖负荷。
在上述步骤中，可以提高第一热源1的功率，并运行第二热源5，将第一热源1和第二热源5整体增加的功率以用于供给采暖负荷。上述提高第一热源1的功率为提高第一热源1总体的功率，可以包括启动未处于运行状态的第一子热源11，和/或提高至少部分已经运行的第一子热源11的功率，或者提高单个的第一热源1的功率等。提高第一热源1的功率，通过第一流量控制装置4将第一热源1提高的该部分功率相对应的流体分流至第二流道3以供给采暖负荷。运行第二热源5，在一种可行的方式中，通过第二流量控制装置19将第二热源5运行产生的功率相对应的流体分流至第四流道7以供给采暖负荷。在另一种可行的方式中，运行第二热源5，通过第二流量控制装置19将第二热源5运行产生的功率相对应的流体分流去进一步升高或降低第一热源1运行产生的流体的温度，最终使得输入至第二末端8的流体的温度达到要求，具体而言，将第一热源1提高的该部分功率相对应的流体通过第二流量控制装置19分流，流经第一换热装置9的第二换热流道以后，再输送至第二末端8中，而将第二热源5生成的流体通过第 二流量控制装置19分流流入第一换热装置9的第一换热流道，在此期间能够与第二换热流道中流经的第一热源1生成的流体进行换热，从而进一步提高或降低第一热源1生成的流体的温度。通过上述方法，第二热源5产生的流体所携带的热量或冷量便通过第一热源1产生的流体，输送给第二末端8。
同理，在第二个实施例的步骤S102中，在联供系统包括第二热源5，第二热源5也可以用于满足采暖负荷的前提下，当采暖负荷被第一热源1满足，且存在对热水负荷的需求时，改变第一热源1的运行状态并运行第二热源5，在使采暖负荷被满足的基础上，供给热水负荷。
在上述步骤中，可以提高第一热源1的功率，并运行第二热源5，将第一热源1和第二热源5整体增加的功率以用于供给热水负荷。同理，上述提高第一热源1的功率为提高第一热源1总体的功率，可以包括启动未处于运行状态的第一子热源11，和/或提高至少部分已经运行的第一子热源11的功率，或者提高单个的第一热源1的功率。
例如，可以通过第一热源1和第二热源5一起对热水进行加热。如第一热源1生成的热流体通过第一流道2可以输送至第二换热装置10的第三换热流道中，以对第三换热装置12中的水进行换热；第二热源5生成的热流体通过第三流道6输送至第二换热装置10的第四换热流道中，以对第三换热装置12中的水进行换热。又例如，第一热源1生成的热流体可以输送至第二换热装置10的第三换热流道中以与第二换热装置10中的水进行换热，从而达到对第二换热装置10中的水的加热目的；第二热源5生成的热流体可以输送至第三换热装置12的第四换热流道中以与第三换热装置12中的水进行换热，从而达到对第三换热装置12中的水的加热目的，第三换热装置12中加热后的水也可以输出供给用户使用。
又例如，也可以控制第一热源1先将水加热至第一预设温度，之后，控制第二热源5再对水进行二次加热。如联供系统包括具有第三换热流道的第二换热装置10和具有第四换热流道的第三换热装置12，第三换热装置12与第二换热装置10相连通，且第二换热装置10具有用于存储水的第一储水腔，第三换热装置12具有用于存储水的第二储水腔，第一储水腔与第二储水腔相连通，从而达到第三换热装置12与第二换热装置10相连通，第三换热流道能与第一储水腔中的存储水进行换热，第四换热流道能与第二储水腔中的存储水进行换热，第二换热装置10的与第一储水腔相连通的出水口能与第三换热装置12的与第二储水腔相连通的进水口相连通，第二换热装置10的与第一储水腔相连通的进水口用于与水源23相连通，第三换热装置12的与第二储水腔相连通的出水口 用于供给热水时，可以控制第一热源1生成的热流体通过第一流道2流入第三换热流道，控制第二热源5生成的热流体通过第三流道6流入第四换热流道。通过上述方法，可以对第一热源1和第二热源5产生热流体的不同能力进行阶梯利用，以提高整个联供系统的能耗比。
在第一个实施例的步骤S102中，若第二热源5的运行比第一热源1的运行更具有优势时，当热水负荷被第一热源1满足，且存在对采暖负荷的需求时，优先运行第二热源5，在使热水负荷被满足的基础上，供给采暖负荷。在第二个实施例的步骤S102中，若第二热源5的运行比第一热源1的运行更具有优势时，当采暖负荷被第一热源1满足，且存在对热水负荷的需求时，优先运行第二热源5，在使采暖负荷被满足的基础上，供给热水负荷。
通过上述方法当存在后出现的或者相对第一热源1供给优先级较低的采暖负荷或热水负荷时，可以优先运行更加具有优势的热源，从而去供给后出现的或者相对第一热源1供给优先级较低的采暖负荷或热水负荷，这样可以使得整个联供系统整体运行的能耗比更高，更加节能环保；或者，可以使得整个联供系统整体运行的性价比更高，加节约运行成本。
在上述步骤后，若执行优先运行第二热源5的步骤之后，若采暖负荷或热水负荷没有被满足，则改变第一热源1的运行状态，供给采暖负荷或热水负荷，从而使得后出现的或者相对第一热源1供给优先级较低的采暖负荷或热水负荷能够最大可能的得到满足。
进一步的，当联供系统包括第二热源5时，在第一个实施例中，在执行改变第一热源1的运行状态，在使热水负荷被满足的基础上，供给采暖负荷的步骤之后，若热水负荷增大，则减少供给采暖负荷的第一子热源11的运行数量，以用于供给增大的热水负荷。若减少用于供给热水负荷的第一子热源11的运行数量的步骤被执行，则可以运行第二热源5，以供给热水负荷；在第二个实施例中，在执行改变第一热源1的运行状态，在使采暖负荷被满足的基础上，供给热水负荷的步骤之后，若采暖负荷增大，则减少用于供给热水负荷的第一子热源11的运行数量，以用于供给增大的采暖负荷。若减少用于供给采暖负荷的第一子热源11的运行数量的步骤被执行，则运行第二热源5，以供给采暖负荷。
通过上述步骤，在存在后出现的或者相对第一热源1供给优先级较低的采暖负荷或热水负荷时，如果优先被供给的或者相对第一热源1供给优先级较高的热水负荷或采暖 负荷增大，则优先改变第一热源1的运行状态，从而尽可能的仅通过第一热源1就满足优先被供给的或者相对第一热源1供给优先级较高的热水负荷或采暖负荷；而通过运行第二热源5，去弥补第一热源1供给后出现的或者相对第一热源1供给优先级较低的采暖负荷或热水负荷的减少量，这样可以使第一热源1满足优先被供给的热水负荷或采暖负荷，同时通过第二热源5的运行，满足后出现的或者相对第一热源1供给优先级较低的采暖负荷或热水负荷，还可以尽可能的避免运行的第二热源5需要后续分流。
本申请中联供系统的控制器18可以执行上述联供系统的控制方法。进一步的，本申请实施例中的联供系统可以包括执行上述联供系统的控制方法的控制器18。作为可行的，该控制器18可以用于与第一热源1、第二热源5通过电力线载波通信或串行通信。控制器18可以用于与第一流量控制装置4、第二流量控制装置19通过电力线载波通信或串行通信。当然的，在其它可行的实施方式中，控制器18可以与第一热源1、第二热源5、第一流量控制装置4和第二流量控制装置19通过其它现有的方式实现通信，如电性连接方式实现通信，有线、无线传输方式实现通讯等等。
上述实施方式仅为本发明的优选实施方式，不能以此来限定本发明保护的范围，本领域的技术人员在本发明的基础上所做的任何非实质性的变化及替换均属于本发明所要求保护的范围。
