采用低功率泵与太阳能热水器置换热水的储热水组合装置 技术领域
本发明涉及太阳能热水器和电热水器领域， 具体是一种采用低功率循环泵与太阳能热水 器置换热水的储热水组合装置。
背景技术
目前， 储水式电热水器虽然具备安装、 使用方便， 热水输出管线短、 即开加热， 带压用 水， 洗浴感好， 安全耐用等特点， 但热水的来源只是单一依靠电加热， 耗电量大， 不节能； 而太阳能热水器， 虽然节能， 但在楼宇住宅楼中应用时存在一定的缺陷， 例如， 太阳能集热 装置和储热水箱连在一体的太阳能热水器， 都在住宅楼顶摆放， 热水输出管线长， 每次使用 热水时， 需放掉管内大量冷水， 即浪费水， 也不方便； 依靠水落差洗浴， 对比储水式电热水 器的自来水压力洗浴， 舒适感差； 在寒冷地区使用时， 为了防止输水管线的冻堵都加装管路 电伴热带， 不但浪费能源， 伴热带老化维护不及时时易短路着火， 不安全。 太阳能集热装置 和储热水箱分开的太阳能热水器， 一种是： 技术要求储热水箱与太阳能集热器距离不能过长 (一般不超过 3米)，所以太阳能集热装置挂在阳台或者建筑南立面上，储热水箱则也挂在阳 台或建筑南墙高于太阳能集热装置的位置上， 例如： 中国专利申请号 03235642.0 (公开号 CN2651665Y)o 由于建筑学对建筑南立面有美观度设计要求， 所以这一种太阳能热水器必须 统一设计、统一安装， 需要一次性投资， 使这一种太阳能热水器不能实现推广； 另有一种是: 太阳能集热装置安装在建筑屋顶， 储热水箱安装在室内， 在开式状态下采用循环泵通过循环 管路进行上、 下水箱（太阳能集热装置水箱和室内储热水箱） 强制循环换热， 来完成两水箱 置换热水过程， 例如： 中国专利申请号 200510056986.5 (公开号 CN1837711A)和申请号 200820210687.1 (公开号 CN201293394Y)专利， 在较高楼房上（2楼以上）使用时， 就需要 采用较高扬程、 较大功率的循环泵， （一般功率： 300W-750W)额定扬程 15-40米， 有效扬 程 8-35米， 噪音较高 （一般在 70分贝以上)， 大于 40分贝的室内噪音标准， 制约推广。 另 夕卜， 在循环泵启动换热时不能正常带压使用热水， 也不方便； 还有， 申请号 200510056986.5 (公开号 CN1837711A)专利， 在每次使用热水时都要开启自来水总阀 （闸阀 8) 非常不方 便。
发明内容
针对上述情况， 本发明提供一种采用低功率泵与太阳能热水器（集热器）置换热水的储 热水组合装置， 并且实现本发明装置与太阳能热水器（集热器）远距离、 大高度差的热水置 换。

该装置按储水式电热水器方式安装， 具有储水式电热水器所有功能特点和热水的使用方 式， 将上水管接口和下水管接口分别与楼顶 （上方） 的太阳能热水器（集热器） 的上水管和 下水管相连， 储热水箱中的低温水与太阳能热水器（集热器） 吸收太阳光能产生的高温水可 以通过该装置控制系统控制各阀件、 泵动作来进行置换， 进行置换时， 带压自来水； 或者， 带压水顶进太阳能热水器（集热器） 的上水管和下水管， 将管中的空气和太阳能热水器（集 热器）上集热水箱中上端的空气通过排气装置顶出系统外， 使太阳能热水器（集热器）及上 水管和下水管与本发明装置处于同一密闭压力系统， 因此就可以利用较低功率的循环泵 （可 选用静音屏蔽泵， 功率： 60W-120W, 噪音低， 40分贝以下， 满足国家标准： 室内小于 45 分贝），将本发明装置储热水箱中的低温水与安装在楼顶的太阳能热水器（集热器）中的高温 热水进行强制循环置换， 解决了开式状态下强制循环换热的传统分体式太阳能热水器需要的 大功率、 高扬程泵的噪音大、 耗电大而制约推广的问题； 也解决储水式电热水器单一的依靠 电加热的大量耗电问题； 解决需要统一安装的传统分体式太阳能热水器， 因为需要一次性投 资而不能实现推广问题； 该装置可以在室内任意用水点安装， 热水输出管线短、 即开加热， 解决现有整体式太阳能热水器在使用使放冷水，不方便问题；置换结束后，太阳能热水器（集 热器） 的上水管和下水管中的水可以依靠自然落差通过排放管路排空， 排空后上水管和下水 管中无水， 无需加装管路防冻电伴热带， 解决现有整体式太阳能热水器在寒冷地区使用时为 了防止管路冻睹需要加装管路电伴热带， 浪费电源， 伴热带老化维护不及时时短路着火、 不 安全问题。
本发明的有益效果是：
1、 本发明是由储热水箱、 电加热器、 循环水泵和各种控制阀、 传感部件以及智能控制 系统组成的， 即可依靠电能制热水又可以依靠太阳能制热水的一种新型的制热水装置， 具有 储水式电热水器所有功能特点和热水的使用方式； 如果将上水管接口、 下水管接口和排放管 接口的管口分别与太阳能热水器（集热器）的上水管和下水管相连及再与一条排空管路相连， 该装置储热水箱中的低温水与太阳能热水器（集热器） 吸收太阳光能产生的高温水通过该装 置中的小功率静音循环泵及各阀件、 功能部件的动作进行置换， 就可以完成太阳能制热水过 程； 该装置可以解决： 储水式电热水器单一的依靠电加热制热水的耗电问题； 也保证了在利 用太阳能制热水的装置在任何天气情况下的热水的连续使用。
2、 本发明装置可以利用较低功率的循环泵（可选用静音屏蔽泵， 功率： 60W-120W, 噪 音低， 40分贝以下， 满足国家标准： 室内小于 45分贝） 实现本发明装置储热水箱中的低温 水与安装在楼顶的太阳能热水器（集热器） 中的、 远距离、 大高度差的热水进行强制循环置 换， 解决了开式状态下强制循环换热的分体式太阳能热水器需要的大功率、 高扬程泵的噪音 大、 耗电大而制约推广的问题， 使利用太阳能制生活热水的节能方法和产品能够被广泛的应 用与推广。
3、 本发明装置可以在室内任意用水点安装， 热水输出管线短、 即开加热， 解决现有整 体式太阳能热水器在使用使放冷水， 不方便问题。
4、、 本发明装置的储热水箱中的低温水与楼顶太阳能集热器水箱中的太阳能制成的高温 水置换结束后， 太阳能热水器（集热器） 的上水管和下水管中的水可以依靠自然落差排空， 排空后上水管和下水管中无水， 无需加装管路防冻电伴热带， 解决现有整体式太阳能热水器 在寒冷地区使用时为了防止管路冻睹需要加装管路电伴热带， 浪费电源， 伴热带老化维护不 及时时短路着火、 不安全问题。
5、 本发明装置通过太阳能制热水时基本上可以实现一次性与太阳能热水器 （集热器） 中的热水进行置换（每天可实现 1-2次)， 置换结束后， 储热水箱中的水温基本上可以升至使 用（洗浴）标准，故此对本发明装置的储热水箱和与本发明装置配套选用的太阳能热水器（集 热器）上的集热水箱的容量及太阳能热水器（集热器） 上的太阳能集热面积进行科学合理的 匹配设计， 就更能达到节水、 节能的目的。 例如： 储热水箱和集热水箱的容量设定 50L， 太 阳能热水器（集热器） 的集热面积设定给 100L容量的集热水箱配套的面积， 即 2倍匹配， 所以太阳能热水器（集热器）吸收光能， 就可能在半天时间将集热水箱中的 50L水加热到设 定温度 (45-70°C ), 与储热水箱中的低温进行置换后， 再用半天时间将集热水箱中与储热水 箱置换过来的 50L低温水再次加热， 达到设计温度 (45-70°0； 在半天晴天或者不算晴朗天 气时， 本发明装置也可能用全天时间利用太阳能制成 50L的、 达到洗浴温度的一箱热水， 以 减少以往的集热面积与水箱容量对等匹配的太阳能热水器在天气不好时， 太阳能制热水温度 达不到洗浴温度， 而需启动电加热的次数， 最大限度的节约了电能； 过去传统有"管路排空" 设计的整体式太阳能热水器， 在每次使用热水时都要向系统外排放水， 本发明装置把过去这 种每天上百次、 数十次的水的排放， 改变为每天 1-2次的储热水箱与集热水箱置换热水后的 "管路排空"设计， 管路排空次数极少， 排水量很少（例如： 1-11楼、 3-35米， 选用内径 9mm 的换热管， 上、 下水管每次排水量 0.6-4L) 实现每天定量排放， 所以可以用容器盛装， 用于 家庭其它用水， 也可以直接对地漏排放， 最大限度的节约用水， 使太阳能制热水装置使用的 更加方便， 推广性更强； 另外由于排水量很少， 所带走的热能量少。
6、 安装在室内的本发明装置可以利用与其远离而安装在楼顶的太阳能热水器（集热器) 制热水，所以可使太阳能热水器（集热器）的推广不必再考虑建筑南立面美观度的设计要求， 可以实现在楼顶有规则的零散摆放、 安装， 无须开发商统一安装， 无一次性巨大投资费用， 使利用太阳能制生活热水的节能方法和产品能够实现广泛的应用与推广。 附图说明

4、 本发明装置与其配套选用的太阳能热水器（集热器） 25置换热水结束后让太阳能热 水器（集热器） 25管路排空功能设计的目的：
如图 1-2、图 1-4所示，上水管 24或者下水管 30排空的目的是本发明装置在置换热水结 束后让集热水箱 26转换为开式状态， 让集热水箱 26通过止水排气阀 28和放气止水阀 36对 外界自由呼吸， 避免太阳能热水器（集热器） 25吸收光能使集热水箱 26中的水温升高产生 热膨胀和高压蒸汽， 造成太阳能热水器（集热器） 25损坏问题。
如图 2-1、 图 3-1所示， 上水管 24和下水管 30排空的目的除了避免集热水箱 26中的水 温升高产生热膨胀和高压蒸汽， 易造成太阳能热水器（集热器） 25损坏外， 让本发明装置在 寒冷地区使用时， 排空的管路无需加装管路防冻电伴热带， 解决现有整体式太阳能热水器在 寒冷地区使用时为了防止管路冻睹需要加装管路电伴热带， 浪费电源， 伴热带老化维护不及 时时短路着火、 不安全问题。
5、 本发明装置的热水使用过程：

6、 本发明装置的报警与安全：
当排空水流经过传感器 10 (可选用水流传感器、 水流开关） 时， 传感器 10虽然动作， 控制仪表 19接收传感器 10 (可选用水流传感器、 水流开关）传感信号， 但在限定的时间内 (正常管路排空时间内）无报警； 排空阀 11为常开阀， 当本发明装置上的阀件损坏时， 会有 不正常的水流连续通过排放管路 14、 排空阀 11排出系统外， 当水流外排时间超过限定的时 间时， 控制仪表 19报警， 使人员可以及时维护， 本发明装置启动电加热时， 储热水箱 18内 的热膨胀水通过泄压阀 4排出； 自来水管路 31无水压力时， 止回阀 3止回作用使储热水箱 18内的水不能流入自来水管路 31中。
本发明装置除了和储水式电热水器一样， 夕卜部都设有进水口和出水口以外， 外部还设有 上水管接口和下水管接口及排放管接口， 按储水式电热水器相同的安装方式将进水口和出水 口分别与自来水管路和热水管路相连， 将水箱上满水， 通电启动电加热， 可以单独使用储水 式电热水器所有功能和热水的使用方式； 如果将上水管路接口、 下水管路接口和排放管接口 的管口分别与太阳能热水器 （集热器） 的上水管和下水管相连及再与一条排空管路相连， 该 装置储热水箱中的低温水与太阳能集热器吸收太阳光能产生的高温水通过该装置中的低功率 循环泵及各阀件、 功能部件的动作进行置换， 就可以完成太阳能制热水功能， 并且置换结束 后太阳能热水器（集热器） 的上水管和下水管中的水可通过排空管路进行排空， 排空无水的 上水管和下水管无需加装电伴热带； 该装置可以在室内任意用水点安装， 输水管线短、 即开 加热， 即节水又节能， 维护及时， 运行安全可靠。
