下面结合图1-图5描述本申请的制热系统及其控制方法。
具体地，本实施例提供一种制热系统，包括：制热器100、太阳能热水器200、导管300、第一阀门400、保温箱500、第一循环泵800、第一温度传感器、第二温度传感器与第一液位传感器。
具体地，制热器100包括蓄热箱110，蓄热箱110具有保温功能，较好地采用外壁为保温材料的保温箱。
可选地，制热器100为制热空调扇，制热空调扇具有盘管，盘管的一部分位于蓄热箱110内，蓄热箱110内填充导热材料。
当不需要空调扇进行制热时，可在蓄热箱110内先存蓄一定的热量。
在需要空调扇进行制热时，可先采取蓄热箱110内存储的热量进行供热。当制热空调扇制热时，蓄热箱110内的热量与盘管进行热交换，再通过风扇将盘管的热量传递至环境中。
太阳能热水器200指的是一般放置在屋顶等能够接受光照位置处，通过接收光照紫外线对水进行加热的热水器。目前，太阳能热水器200多用于洗澡等人们的日常生活用水所需。
具体地，太阳能热水器200具有储水箱210，用于存储太阳能热水器 200加热的热水，储水箱210具有出水口211与回水口212。一般地，储水箱210位于太阳能热水器200的本体上，通过水管将存储的热水导流至水龙头，以供用户洗澡等所需热水。
保温箱500具有第一进水口510与第一排水口520，导管300包括第一导管310与第二导管320，第一导管310连接在出水口211与第一进水口510之间，第二导管320的一端连接第一排水口520，第二导管320部分位于蓄热箱110内。
一般而言，太阳能热水器200的储水箱210容量不大，多数是在参考用户洗澡等生活用水量所设计，因此在直接向制热器100一端输送热水时，容易导致太阳能热水器200内的热水量不满足用户的其他生活用水。
本实施例通过设置保温箱500，太阳能热水器200产出的热水可导流至保温箱500内进行保温储存，提高太阳能热水器200制备热水的体积量，以同时满足制热器100供热，以及用户的日常生活用水。
具体地，储水箱210内的热水先通过第一导管310导流到保温箱500内，由于储水箱210的高度多数情况下高于保温箱500的高度，储水箱210内的热水可在重力作用下直流到保温箱500内。或者，在第一导管310上设置循环泵，以确保储水箱210内的热水能够导流到保温箱500内。
保温箱500内的热水通过第二导管320与蓄热箱110进行热交换。具体地，第二导管320内热交换后的水可直接排走，或者第二导管320的另一端连接回水口212，第二导管320上设有第一循环泵800，导管300内与蓄热箱110热交换后的水通过第一循环泵800返回到太阳能热水器200的储水箱210中。

具体地，第二导管320部分位于蓄热箱110内，保温箱500内的热水通过第二导管320与蓄热箱110进行热交换。
具体地，第一温度传感器位于保温箱500内，用于检测保温箱500内温度，并发送至控制装置。
具体地，第二温度传感器位于储水箱210内，用于检测储水箱210内 温度，并发送至控制装置。
具体地，第一液位传感器位于保温箱500内，用于检测保温箱500内液面高度，并发送至控制装置。
具体地，控制装置分别与所述第一温度传感器、所述第二温度传感器和所述第一液位传感器通讯连接，用于接收保温箱温度、储水箱温度与保温箱液面高度，计算保温箱液面高度比，依据上述参数控制太阳能热水器向保温箱提供热水。
较好地，本实施例所述的制热系统还包括回水箱600，回水箱600具有第二进水口610与第二排水口620，第二导管320包括第三导管321与第四导管322，第三导管321连接在第一排水口520与第二进水口610之间，第四导管322连接在第二排水口620与回水口212之间，第三导管321部分位于蓄热箱110内，第一循环泵800设在第四导管322上，第二阀门410设在第三导管321上，第四导管322上设有第三阀门420。
具体地，如图2所示，保温箱500与回水箱600为一个整体箱体，保温箱500与回水箱600之间通过绝热层进行分隔。一般地，保温箱500内的水温多在50℃以上，而与蓄热箱110进行热交换后的热水会降低到30℃左右或以下，通过回水箱600对热交换后的水进行储存，以在合适的情况下返回至储水箱210内。
保温箱500内的热水先通过第三导管321与蓄热箱110进行热交换，热交换后的水进入到回水箱600中，并在第一循环泵800的驱动下返回到储水箱210中。
较好地，第三导管321上设有第二循环泵810，以便于更好的驱动保温箱500内的热水在第三导管321内流通，控制流速，提高第三导管321内的热水与蓄热箱110的热交换效率。
较好地，第三导管321上设有第二阀门410，以对第三导管321的流动进行控制。
较好地，保温箱500与回水箱600之间通过导通管700连通，导通管700上设有第四阀门430；回水箱600设在保温箱500下方，或者导通管700上设有第三循环泵。当保温箱500内留存低温水时，可先将保温箱500内的低温水排至回水箱600内，再控制储水箱210内的热水导流到保温箱 500内。
较好地，制热系统还包括第二液位传感器，第二液位传感器位于回水箱600内，用于检测回水箱600内液面高度。
较好地，制热系统还包括紫外传感器，紫外传感器用于检测太阳能热水器200接收的紫外线强度。
在上述制热系统的具体实施方式基础上，本实施例还提供一种制热系统的控制方法，如图4所示，包括如下步骤：
步骤S100、获取保温箱温度Tb、储水箱温度Tc与保温箱液面高度，确定保温箱液面高度比Hb；
步骤S200、基于保温箱温度Tb、储水箱温度Tc与保温箱液面高度比Hb，控制储水箱210与保温箱500之间第一阀门400的启闭。
具体地，太阳能热水器在太阳光照射下，能够对水进行加热，在储水箱温度Tc加热到一定的温度时，才满足向保温箱500内注入热水的要求，并且通过保温箱温度Tb来控制储水箱温度Tc的热水是否向保温箱500内注入，以及通过保温箱液面高度比Hb来调节储水箱210向保温箱500内注入热水的水量。
本实施例通过保温箱温度Tb、储水箱温度Tc与保温箱液面高度比Hb，控制第一阀门400的启闭，以在储水箱210内热水满足热量需求时向保温箱500内注入热水，并根据保温箱500内的温度和液面高度比，来调控储水箱210向保温箱500内注入热水的开启时间与关闭时间，以确保保温箱500内存储有最大热量的热水，以便于更好的向蓄热箱110进行加热。
具体地，步骤200中，基于保温箱温度Tb、储水箱温度Tc与保温箱液面高度比Hb，控制储水箱210与保温箱500之间第一阀门400的启闭包括：
当储水箱温度Tc大于或等于第二预设温度T2时，开启第一阀门400，并基于保温箱温度Tb与保温箱液面高度比Hb确定第一阀门400的开启时间与开启时长。
具体地，第二预设温度T2在60℃以上，例如第二预设温度T2取值65℃，当储水箱温度Tc大于或等于65℃时，向第一阀门400发送开启信号，并基于保温箱温度Tb与保温箱液面高度比Hb确定第一阀门400的开 启时间与开启时长。
具体地，基于保温箱温度Tb与保温箱液面高度比Hb确定第一阀门400的开启时间与开启时长包括：
当保温箱温度Tb小于第一预设温度T1并且保温箱液面高度比Hb大于第一预设高度比H1时，控制第一阀门400处于关闭状，开启第四阀门430，直至保温箱液面高度比Hb降低至小于或等于第一预设高度比H1，关闭第四阀门430，开启第一阀门400，直至所述保温箱液面高度比Hb大于或等于第二预设高度比H2时，关闭所述第一阀门400。第一预设温度T1在45℃至55℃范围内，优选50℃。第一预设高度比H1小于5％，优选为0％。当保温箱温度Tb小于50℃并且保温箱液面高度比Hb大于0％时，认定保温箱500内留存有水温不高的冷水，如若注入储水箱210的热水，将导致保温箱500内冷水与热水混合，注入热水后的保温箱500内水温无法满足向蓄热箱110供热的要求，因此先开启第四阀门430，将保温箱500内的冷水排出；直至保温箱液面高度比Hb降低至等于0％，表明保温箱500内的冷水排尽，关闭第四阀门430，开启第一阀门400，储水箱210内的热水注入到保温箱500内。具体地，第二预设高度比H2在90％以上，优选为95％，当保温箱500内热水量达到95％以上时，保温箱500热水充满，关闭第一阀门400，储水箱210停止向保温箱500内注入热水。
当保温箱温度Tb小于第一预设温度T1并且保温箱液面高度比Hb小于或等于第一预设高度比H1时，开启第一阀门400，直至保温箱液面高度比Hb大于或等于第二预设高度比H2时，关闭第一阀门400。当保温箱温度Tb小于50℃并且保温箱液面高度比Hb等于0％时，认定保温箱500内不存在冷水，直接开启第一阀门400，储水箱210内的热水注入到保温箱500内。当保温箱500内热水量达到95％以上时，保温箱500热水充满，关闭第一阀门400，储水箱210停止向保温箱500内注入热水。
具体地，基于保温箱温度Tb与保温箱液面高度比Hb确定第一阀门400的开启时间与开启时长还包括：
当保温箱温度Tb大于或等于第一预设温度T1并且保温箱液面高度比Hb小于或等于第三预设高度比H3时，开启第一阀门400，直至保温箱液面高度比Hb大于或等于第二预设高度比H2时关闭第一阀门400。
具体地，第三预设高度比H3在55％至65％范围内，优选为60％，在保温箱温度Tb大于或等于50℃，并且保温箱液面高度比Hb小于或等于60％时，才开启第一阀门400，直至保温箱液面高度比Hb增大至95％，表明保温箱500热水注满，关闭第一阀门400。在保温箱温度Tb高于50℃并且保温箱液面高度比Hb大于60％时，保温箱500内热水满足蓄热箱11的换热需求，此时以储水箱210水量满足其他用水为先，在保温箱液面高度比Hb小于或等于60％时才通过储水箱210注入热水，以在太阳能热水器200与制热器100之间的热水共用平衡。
具体地，在运行步骤S200时，还获取回水箱液面高度，确定回水箱液面高度比，当回水箱液面高度比大于或等于第四预设高度比H4时，开启第三阀门420与第一循环泵800，直至回水箱液面高度比降低至小于或等于第五预设高度比H5。
具体地，第四预设高度比H4指的是回水箱内水位液面较高，需要对回水箱600进行排水时的预设高度比；第五预设高度比H5指的是回水箱600内水位安全比，在回水箱600内水位小于第五预设高度比H5时，不需要将回水箱600内的水排出，较好地在5％至30％范围内。当回水箱液面高度比大于或等于第四预设高度比H4时，开启第三阀门420与第一循环泵800，将回水箱600内的水导回至储水箱210内，直至回水箱液面高度比降低至小于或等于第五预设高度比H5，防止回水箱600内存满水而阻碍保温箱500与蓄热箱110之间的热交换。
具体地，存储器内存储有多个第四预设高度比H4，在满足对应条件时，第四预设高度比H4获取不同的取值。
具体地，在储水箱温度Tc小于第二预设温度T2时，第四预设高度比H4在70％至90％范围内，优选为80％。当储水箱温度Tc小于65℃时，储水箱210内温度不高，不适宜向储水箱210内回流水，导致储水箱210内水温下降，在回水箱600的水量达到80％以上时，再将回水箱600内的水导流回储水箱210内。
可选地，在保温箱温度Tb小于第一预设温度T1，并且储水箱温度Tc小于第二预设温度T2时，第四预设高度比H4在70％至90％范围内，优选为80％。当保温箱温度Tb小于50℃，并且储水箱温度Tc小于65℃时， 储水箱210内温度不高，不适宜向储水箱210内注入回水箱600中温度较低的水，在回水箱600的水量达到80％以上时，再将回水箱600内的水导流回储水箱210内。
具体地，在运行步骤S200时，还获取紫外强度值，当紫外强度值小于第一预设强度值时，第四预设高度比H4在40％至90％范围内，优选为80％；
当紫外强度值大于第二预设强度值时，第四预设高度比H4在10％至30％范围内，优选为20％；
第一预设强度值小于第二预设强度值。
具体地，当紫外强度值小于第一预设强度值时，指的是当前太阳能热水器接收的紫外线强度不高，太阳能热水器转化为热水的速度不高，或者转化为热水的温度不高。只要紫外强度值小于第一预设强度值，不论保温箱500与储水箱210的温度如何，第四预设高度比H4取值均为80％，以防止回水箱600内的水回流至储水箱210内而导致水温上升进一步减慢。
具体地，当紫外强度值大于第二预设强度值时，指的是当前太阳能热水器接收的紫外线强度较高，太阳能热水器转化为热水的速度较快，或者转化为热水的温度较高。只要紫外强度值大于第一预设强度值，不论保温箱500与储水箱210的温度如何，第四预设高度比H4取值均为20％，以在回水箱600中存留的水量超过20％就导流回储水箱210内，也不会对储水箱210内水温造成较大的影响。
同样地，步骤S200中，还获取紫外强度值，第二预设高度比H2在紫外强度值小于第一预设强度值时的取值小于紫外强度值大于第二预设强度值时的取值，第一预设强度值小于第二预设强度值。当光照强度比较大时，储水箱内水温上升以及最终温度较高，因此储水箱210向保温箱500内注水的水量可以比光照强度不足时大，即便储水箱210向保温箱500注入了较多的热水，足够的光照强度也会尽快加热储水箱210内的热水，满足太阳能热水器200向用户的生活用水提供热水。
同样地，步骤S200中，还获取紫外强度值，第三预设高度比H3在紫外强度值小于第一预设强度值时的取值小于紫外强度值大于第二预设强度值时的取值，第一预设强度值小于第二预设强度值。当光照强度比较大时，储水箱内水温上升以及最终温度较高，因此保温箱500内水量不足30％时， 储水箱210就向保温箱500内注入热水，即便储水箱210向保温箱500注入了较多的热水，足够的光照强度也会尽快加热储水箱210内的热水，满足太阳能热水器200向用户的生活用水提供热水。
