Description

一种耦合热泵热水器的温控系统 技术领域
本发明涉及一种耦合热泵热水器的温控系统，更具体地讲，本发明涉及一种利用循环水耦合热泵热水器的温控系统。
背景技术
为了舒适的生活，人们往往需要安装空调、地暖、热水器等设备来调节室温以及提供使用的热水。热水器通常会选用热泵热水器。
热泵热水器，也称为空气源热泵热水器，即空气能热水器，其工作原理与空调器极为相似，采用少量的电能驱动压缩机运行，高压的液态工质经过膨胀阀后在蒸发器内蒸发为气态，并从空气中吸收大量的热能；气态工质被压缩机压缩成为高温、高压的液态工质，然后进入冷凝器放热而把水加热....如此不断地循环加热，可以把水加热至50℃-65℃。在这一过程中，消耗1份的电能驱动压缩机运行，可同时从环境空气中吸收转移约4份的热量到水中。因此，相对于普通的电热水器来说，空气能热水器可以节约近3/4的电能。即普通电热水器消耗4Kw.h电能产出的热水，使用空气能热水器只需要1Kw.h电就可以了。
而上述的这些设备都需要独立的室外主机来与环境进行热量交换，但是在公寓、出租屋等特殊居住地，由于整体空间较小，很难安装下如此多的室外主机，安装、维护困难，导致用户生活不够便利。
因此，有必要提供一种温控系统，其既能提供日常生活所需的生活热水，又能调节室内环境温度，而且占用空间小、节约电能。
发明内容
本发明的目的是提供一种利用循环水耦合热泵热水器的温控系统，从而一次性地解决室内热水供应和室温调节的问题。
为了实现本发明的发明目的，本发明提供了一种利用循环水耦合热泵热水器的温控系统，该温控系统包括：
换热主机，该换热主机上设置有换热器和散热系统；
供水管道，该供水管道与所采用的换热器相连通；
回水管道，该回水管道与供水管道之间并联安装有至少一个室温控制装置；
热泵热水器，该热泵热水器包括温升水箱、热泵蒸发器和压缩机；其中，温升水箱上设置有换热管，该换热管两端分别与热泵蒸发器和压缩机相连通；换热管与热泵蒸发器之间设置有膨胀阀；热泵蒸发器与压缩机相连通，并耦合至回水管道或供水管道上；温升水箱上设置有冷水入口和热水出口；
缓冲水箱，该缓冲水箱分别与回水管道末端和换热器相连通，缓冲水箱、供水管道和回水管道内设置有循环水体；
水泵，该水泵设置于供水管道或回水管道上。
在上述的技术方案中，换热主机对循环水体进行温度调节，使一定温度的水从供水管道流出，然后通过各室温控制装置可 以对室内温度进行调节，之后水温发生变化并通过回水管道回流至缓冲水箱内之后继续流动至换热主机内进行调温循环，而热泵热水器上的热泵蒸发器耦合至回水管道或供水管道上，热泵蒸发器吸收其内的循环水体的热量，使热泵蒸发器内的热媒温度升高并使循环水体水温下降，然后通过压缩机和换热管对温升水箱内的水进行加热，以提供生活热水；热泵热水器原本需要一个独立的室外主机，利用耦合的形式，可将热泵热水器的室外主机通过循环水体由换热主机进行代劳，使室温调节系统和热水供应系统共用一个换热主机，从而节省空间占用，且多户可以共用一台换热主机，对于公寓、出租屋这种性质的居住房具有显著意义。同时，循环水体本身就具有一定的蓄能能力，即使换热主机不工作的状态下，循环水体依然能具备较大的热能储能，供热泵热水器使用，使整体也更为节能。在夏天对换热主机功率要求较大的情况下，热泵热水器上的热泵蒸发器使循环水体的水温降低，而由于夏天本身就需要输出低温水体，因此耦合反而可以减轻换热主机的负担；在冬天，虽然热泵热水器会增大换热主机的负担，但换热主机本身的制热能力就强于制冷能力，冬天换热主机的的功率有足够的富余，因此通过热泵热水器也可以很好的平衡换热主机的四季负担，使换热主机的四季功率更加均衡，从而使整体效能更加均衡。
优选地，在上述本发明的技术方案中，换热主机可以包括换热蒸发器、四通阀、换热压缩机和电子膨胀阀；其中，换热蒸发器的一端与四通阀相连通，另一端与电子膨胀阀相连通， 而电子膨胀阀的另一端则连通至换热器上；换热压缩机的两个端口分别与四通阀相连通，而四通阀又与换热器相连通。
作为上述技术方案的进一步改进，换热管可以呈螺旋状固定于温升水箱内。
作为上述技术方案的进一步改进，缓冲水箱可以设置于换热主机底部，以使整个结构更为紧凑。
在本发明的技术方案中，室温控制装置优选为多个，例如可以包括至少一个的风机盘管和/或至少一个的地暖，从而在天热时可以利用风机盘管为多个房间提供冷风，而在天冷时可以利用地暖为多个房间供热。
作为上述技术方案的进一步改进，热泵蒸发器可串联耦合至回水管道上。
在本发明的技术方案中，温控系统还可以进一步包括分流支路，该分流支路与回水管道或供水管道并联，其中，热泵蒸发器设在分流支路。
设立分流支路的优点是，可以降低回水管道或进水管道的水阻力，平衡了回水管道或进水管道及分流支路的水压力，从而可以保持温控系统处于较高的效能，而且方便安装。
在本发明设立分流支路的技术方案中，优选地，分流支路的直径小于回水管道或供水管道直径。
在本发明设立分流支路的技术方案中，为了更好地控制水循环回路以及系统的压力，温控系统还可以进一步包括压力调节阀，该压力调节阀可以设在回水管道或供水管道上，其中，分流支路与压力 调节阀两端的回水管道或供水管道连通。
上述的压力调节阀可以为机械式阀，也可以为电动式阀；如果压力调节阀选用电动式阀，则更便于使其与热泵热水器联动。
在本发明设立分流支路的技术方案中，温控系统还可以进一步包括三通阀，该三通阀设在回水管道或供水管道上、且与分流支路的一端连通。
本发明的温控系统将热泵蒸发器耦合于回水管道或供水管道上，通过耦合的形式，将热泵热水器的室外主机通过循环水体由换热主机进行代劳，从而使室温调节系统和热水供应系统共用一个换热主机，进而节省空间占用，而且可以多户共用一台换热主机；从某种意义讲，本发明的温控系统可以看作是一种耦合热泵热水器的热泵空调，而且通过设置分流支路，可以降低回水管道或进水管道的水阻力，从而平衡回水管道或进水管道及分流支路的水压力，保证整个温控系统处于较高的效能。

参照图1至图2，其显示了本发明利用循环水耦合热泵热水器的温控系统的一具体实施方式，该具体实施方式中温控系 统包括：
换热主机1，该换热主机1上设置有换热器11和散热系统；
供水管道2，该供水管道2与换热器11相连通；
回水管道3，该回水管道3与供水管道2之间并联安装有至少一个室温控制装置如41、42等；
热泵热水器6，该热泵热水器6包括温升水箱61、热泵蒸发器63和压缩机64；温升水箱61上设置有换热管62，换热管62两端分别与热泵蒸发器63和压缩机64相连通；换热管62与热泵蒸发器63之间设置有膨胀阀67，热泵蒸发器63与压缩机64相连通，热泵蒸发器63耦合至回水管道3或供水管道2上，温升水箱上设置有冷水入口65和热水出口66；
缓冲水箱，该缓冲水箱与换热器11以及回水管道3末端相连通，缓冲水箱、供水管道2和回水管道3内设置有循环水体；
水泵，该水泵设置于供水管道2或回水管道3上。
换热主机1对循环水体进行温度调节，使一定温度的水从供水管道2流出，然后通过室温控制装置可以对室内温度进行调节，之后水温发生变化并通过回水管道3回流至缓冲水箱内之后继续流动至换热主机1内进行调温循环；热泵热水器6上的热泵蒸发器63耦合至回水管道3或供水管道2上，热泵蒸发器63吸收其内的循环水体的热量，从而使热泵蒸发器63内的热媒温度升高并使循环水体的水温下降，然后通过压缩机64和换热管62对温升水箱61内的水进行加热，从而提供生活热水；热泵热水器6原本需要一个独立的室外主机，而通过耦合的形 式，将热泵热水器6的室外主机通过循环水体由换热主机1进行代劳，从而使室温调节系统和热水供应系统共用一个换热主机1，进而节省空间占用，而且可以多户共用一台换热主机1。
由于循环水体本身就具有一定的蓄能能力，即使在换热主机1不工作的状态下，循环水体依然能具备较大的热能储能，可供热泵热水器6使用，从而使整体也更为节能。
在夏天对换热主机1功率要求较大的情况下，热泵热水器6上的热泵蒸发器63使循环水体的水温降低，而由于夏天本身就需要输出低温水体，因此耦合反而可以减轻换热主机1的负担；而冬天虽然热泵热水器6会增大换热主机1的负担，但是换热主机1本身的制热能力就强于制冷能力，在冬天换热主机1的功率有足够的富余，因此通过热泵热水器6也可很好地平衡换热主机1的四季负担，使换热主机1的四季功率更加均衡。
在上述的方案中，优选热泵蒸发器63串联耦合至回水管道3上，热泵蒸发器63也可以串联耦合至供水管道2上，热泵蒸发器63也可以通过并联的形式耦合至回水管道3和供水管道2上，具体选择根据使用需求和安装需求来决定。
进一步地，换热主机1包括换热蒸发器12、四通阀15、换热压缩机13和电子膨胀阀14；换热蒸发器12的一端与四通阀15相连通，；换热蒸发器12的另一端与电子膨胀阀14相连通；电子膨胀阀14的另一端连通至换热器11上，压缩机64的两个端口分别与四通阀15相连通，四通阀15与换热器11相连通。
优选地，换热管62可以呈螺旋状固定于温升水箱61内， 换热管62也可以呈螺旋状盘绕于温升水箱61的外表面，具体的实施方式根据生产需求来实时选择。
作为一种更具体的实施方案，缓冲水箱可以设置于换热主机1底部。
作为另一种更具体的实施方案，室温控制装置可以为风机盘管41和/或地暖42。
图3所示为本发明利用循环水耦合热泵热水器的温控系统的另一具体实施方式，其中，温控系统包括换热主机1、供水管路2、回水管道3、温控装置4、缓冲水箱5和热泵热水器6；换热主机1包括换热器11和散热系统；热泵热水器6结构如图2所示，也包括温升水箱61、热泵蒸发器63和压缩机64，温升水箱61上设置有换热管62，换热管62两端分别与热泵蒸发器63和压缩机64相连通；热泵蒸发器63与压缩机64相连通，热泵蒸发器63耦合至回水管道3或供水管道2上，温升水箱上设置有冷水入口和热水出口；热泵蒸发器63耦合至回水管道3或供水管道2上；回水管道3与供水管道2之间并联安装有至少一个室温控制装置4；
换热器11和热泵蒸发器63采用的双流道换热方式；温控装置4为室温控制装置可以为风机盘管和/或地暖；
图3所示的温控系统还包括分流支路7；
该分流支路7与回水管道3并联，热泵蒸发器63设在分流支路上。分流支路7的直径和回水管道的直径匹配，确保回水畅通，分流支路的流量和热泵蒸发器63的能量匹配。这样的技术 方案消除了现有技术直接串联在回水管道3、从而影响循环的缺陷。回水管道3的局部和分流支路7可以作为一个整体部件，消费者安装时，安装快捷方便；
或者说：分流支路7包括分流进液管和分流出液管，分流进液管与热泵蒸发器63进流端连接，分流出管与热泵蒸发器63的出液端连通。
可选择地，分流支路的直径小于回水管道或供水管道直径。
图3所示的温控系统还可包括压力调节阀8，压力调节阀8设在回水管道3或供水管道2上，分流支路与压力调节阀8两端的回水管道或供水管道连通。分流支路7和压力调节阀8制成一个部件，使用安装时，安装方便。
压力调节阀8可以为机械式阀；压力调节阀和分流支路7构成并联部件，根据批次、功能相应要求，成批量生产；
压力调节阀8也可以为电动式阀，压力调节阀8和热泵热水器6联动。采用这样的结构，在热泵热水器6的工作时，分流支路7的流量及压力自动增加，停止工作时，分流支路7的流量及压力自动减少。即，热泵热水器6工作、静止状态，分流支路7的流量及压力转换。
图4所示所示为本发明利用循环水耦合热泵热水器的温控系统的再一具体实施方式，其与图3所示的温控系统基本相同，但本实施方式还包括三通阀9，三通阀9设在回水管道3或供水管道2上且与分流支路7的一端连通，热泵蒸发器63设在分流支路7上。
尽管说明给出和描述了本发明的部分具体实施方式，本领域的普 通技术人员可以理解：在不脱离本发明的原理和宗旨的情况下可以对这些实施方式进行多种变化、修改、替换和变型。
