发明名称：一种可利用太阳辐射和天空冷辐射实现昼夜分时热电冷 供应的 PVT热泵系统
技术领域
[0001] 本发明涉及一种利用太阳能光伏发电技术和 PVT热泵技术， 吸收太阳辐射和天 空冷辐射， 实现昼夜分吋热电冷供应的 PVT热泵系统。
背景技术
[0002] 太阳能资源是一种取之不尽用之不竭的新型可再生能源， 面对化石燃料资源日 益枯竭、 环境污染严重的现状， 太阳能等可再生能源是化石燃料的有效替代者 。 太阳能光热利用和光电利用技术目前已经较为成熟， 已经在能源动力、 制冷 空调、 社会生活、 航天科技等领域中有着十分广泛的应用， 但是由于太阳能资 源本身存在的能量密度低、 周期性强、 稳定性差等缺点， 对太阳能能源的利用 也存在诸多问题， 对太阳能资源利用率低和太阳能系统设备利用率低是目前太 阳能能源利用的瓶颈， 其原因不仅与当前的发展技术有关， 而且还与其对太阳 能使用的单一性有关。
[0003] 为克服太阳能资源使用的单一性， 前人已有的研究成果已经在太阳能 PVT热电 联供技术方面做了探索， 该技术可以利用太阳辐射能量在白天实现热能和电能 的输出， 但在夏季有冷量需求吋却无法实现冷量输出， 不能全天候运行， 设备 利用率低。 另有研究表明， 直膨式太阳能热泵空调及热水系统可以实现白天和 夜晚的联合运行， 输出热能和空调制冷量， 但是需要辅助风冷换热器和设置阀 门切换， 系统较为复杂且控制难度高， 而且系统不具备发电功能， 无法输出高 品位的电能资源， 系统运行需要额外的大量的电能输入， 使得系统的性能系数 不高， 能量利用率低。 而且常用的太阳能 PVT组件以管板式为主， 另有吹胀式组 件多以双面吹胀型为主， 虽然加工难度低， 但其双面外鼓型流道不利于与光伏 组件相层压结合， 对其整体制热发电性能的提高造成阻碍。 建筑是人类赖以生 存的环境， 在全年不同吋段具有电能、 热能和冷量的能源需求， 但建筑自身可 利用的空间有限， 如何能在最小的空间占用面积上、 利用最简化的系统来实现 三种能量的分吋输出， 是提高系统设备利用率和能量利用率的关键。
[0004] 昼夜分吋热电冷供应的 PVT热泵系统是 PVT热泵技术与太阳能光伏发电技术的 有机结合， 可以在不同吋段和不同工作模式下， 实现在同一套系统上同吋输出 电能、 热能和冷量的一机多用的目的， 并且能够在最大程度上提高能源的利用 率， 系统全天候运行， 提高了设备利用率， 节能效果显著。 因此， 发明一种设 备组成简单、 能源利用率高、 系统内设备利用率高、 实现昼夜分吋热电冷供应 的新型 PVT热泵系统及 PVT光电 -蒸发 /冷凝组件， 具有重要的实用价值。

VT热泵系统及新型 PVT光电 -蒸发 /冷凝组件。
问题的解决方案
技术解决方案
[0006] 本发明的技术方案：
[0007] 一种可利用太阳辐射和天空冷辐射实现昼夜分吋热电冷供应的 PVT热泵系统， 同吋利用了光伏发电技术和 PVT热泵技术， 二者间在功能上相对独立而又互相促 进； 系统的主要能量来源为太阳辐射能和天空长波冷辐射能， 能量传递方式为 辐射和导热， 并辅助以对流换热的方式， 实现在不同吋段以及不同工作模式下 ， 在同一套系统上， 输出电能、 热能和冷量， 实现一机多用、 昼夜分吋热电冷 三联供；
[0008] PVT热泵系统包括 PVT光电 -蒸发 /冷凝组件 1、 压缩机 2、 四通换向阀 3、 蓄热水 箱 4、 干燥过滤器 5、 电子膨胀阀 6、 制冷剂单向阀组 7、 用冷末端蒸发器， 通过 四通换向阀 3和制冷剂电磁阀 8~11的控制， 实现热泵制热 /制冷模式的切换； 电力 系统包括逆变器 12以及相应的配电柜和蓄电池等；
[0009] 在太阳辐射强度较大的白天工作在热电联供模式下， PVT热泵系统内的制冷剂 经过压缩机 2排汽通过四通换向阀 3， 与作为热泵系统冷凝器的蓄热水箱 4内的高 效换热器进口相连， 出口通过制冷剂单向阀组 7后， 依次与干燥过滤器 5、 电子 膨胀阀 6相连， 然后与作为 PVT热泵系统蒸发器的 PVT光电 -蒸发 /冷凝组件 1的进 口相连， 液态制冷剂在 PVT光电 -蒸发 /冷凝组件 1内吸热蒸发， 体积逐渐膨胀， 制冷剂流道也沿管路逐渐分流， 由两管制分流为多管制， 由出口流出， 通过四 通换向阀 3再与压缩机 2吸汽口相连， 构成封闭的热泵系统制热循环； 蓄热水箱 内置的高效换热器进口和出口处分别由第三制冷剂电磁阀 10和第四制冷剂电磁 阀 11控制； 在蓄热水箱 4内， 内置的高效换热器直接加热蓄热水箱 4内的水， 作 为采暖或生活热水的热量来源。
[0010] 在夏季和有冷量需求的过渡季夜晚以及阴雨天气的白天工作在制冷模式下， 用 冷末端蒸发器出口内的制冷剂通过四通换向阀 3进入压缩机 2排汽后， 与作为 PVT 热泵系统冷凝器的 PVT光电 -蒸发 /冷凝组件 1的进口相连； 气态制冷剂在 PVT光电 -蒸发 /冷凝组件 1内放热冷凝， 由气态冷凝为液态， 体积逐渐缩小， 制冷剂流道 也沿管路由多管制汇流为两管制， 最终由出口流出， 经过制冷剂单向阀组 7后依 次与干燥过滤器 5、 电子膨胀阀 6相连， 进入用冷末端蒸发器入口； 用冷末端蒸 发器出口和入口处分别由第一制冷剂电磁阀 8和第二制冷剂电磁阀 9控制； PVT热 泵系统产生的冷量通过用冷末端的各个蒸发器输送到各用冷区域， 也可经过储 存再输送到不同吋段不同冷量需求的用冷区域。
[0011] 所述的制冷剂单向阀组 7由四个单向阀连接为环形， 分为两组， 对向连接； 干 燥过滤器 5和电子膨胀阀 6分别连接在两组单向阀间， 保证制冷剂流向始终从干 燥过滤器 5到电子膨胀阀 6;
[0012] 所述的 PVT光电 -蒸发 /冷凝组件 1， 由高效吹胀式换热板和光伏组件层压而成； 换热板是采用全铝制板单面吹胀加工工艺制作而成的， 其顶面为平板， 底面为 制冷剂流道， 为蛇形盘管式流道， 由进口的两管制逐渐分流为多管制， 分流和 汇流处均由圆滑管路过渡， 设置有一进两出共三个连接口， 为了提高换热板的 抗变形强度， 四周制作 L形向下的折边， 换热板的表面均喷涂利于增强光谱吸收 能力的选择性吸收涂层。 顶面的平板更容易与光伏组件通过层压相紧密结合， 减小传热热阻， 增加导热性能， 提高能量利用率。 光伏组件采用黑色的光伏背 板， 以增强吸收光谱的能力和增加导热强度。 EVA胶膜作为层压过程中的粘性 介质， 它是一种热固性有粘性的胶膜， 用于放在光伏组件与换热板中间。 由于 E VA胶膜在粘着力、 耐久性、 光学特性等方面具有的优越性， 在组件中对光伏组 件起粘附和保护作用， 而且具有较高的透光性， 稳定性和绝缘性。

有益效果
[0013] 本发明的有益效果：
[0014] (1) 一种可利用太阳辐射和天空冷辐射实现昼夜分吋热电冷供应的 PVT热泵 系统的发电、 制热和制冷三联供的效果是在 PVT光电 -蒸发 /冷凝组件上实现的。 在冬季、 夏季和过渡季太阳辐射强度较大的白天， 系统可工作在热电联供模式
， 此吋 PVT光电 -蒸发 /冷凝组件是作为热泵系统的蒸发器吸收热量的， 组件在白 天吸收太阳辐射能量， 一部分能量通过光生伏特效应将光能转化为电能输出， 另一部分太阳辐射能量则被组件下层的换热板吸收。 另外， 光伏组件发电的同 吋自身会发热而产生大量的热量， 这部分热量聚积在光伏组件上则会降低其发 电效率。 PVT光电 -蒸发 /冷凝组件在热电联供模式下工作吋， 光伏组件自身发热 量会以热传导的方式传到下层换热板上， 这部分热量连同太阳辐射热量， 以及 换热板与空气自然对流换热量， 作为热泵系统的热量来源， 被作为蒸发器的 PVT 光电 -蒸发 /冷凝组件吸收， 制取热水储存在蓄热水箱中， 同吋可以显著提高光伏 组件的发电效率， 实现高效率的热电联产。 在夏季和有冷量需求的过渡季夜晚
， 系统可工作在制冷模式下， PVT光电 -蒸发 /冷凝组件是作为热泵系统的冷凝器 放出热量的， 组件吸收来自天空的长波冷辐射能， 通过组件背面作为冷凝器的 换热板， 以辐射换热和自然对流换热的方式， 与天空和空气换热， 通过制冷循 环制取冷量， 直接供给用冷区域的末端蒸发器， 产生的冷量可直接利用或储存 。 在夏季阴雨天气下太阳辐射强度较低的白天， 系统同样可工作在制冷模式下 ， 组件吸收天空长波冷辐射能， 以及风雨对组件表面冲刷的对流换热量， 通过 制冷循环制取冷量。
[0015] (2) PVT光电 -蒸发 /冷凝组件为易于与建筑相结合实现太阳能建筑一体化的构 件， 为平板型结构， 结构简单轻薄， 成本低廉， 不仅适用于倾斜安装在斜屋顶 或平屋面上， 而且适用于做成建筑幕墙的形式垂直挂装在建筑外立面上， 为实 现由耗能型建筑到产能型建筑的转变奠定了基础， 真正实现太阳能建筑一体化 及昼夜分吋热电冷三联供， 为大规模工程应用奠定了基础。
[0016] (3) 一种可利用太阳辐射和天空冷辐射实现昼夜分吋热电冷供应的 PVT热泵 系统采用 PVT热泵技术， 大大提高了组件的效率和热泵系统性能系数。 热泵循环 带走了光伏组件发电过程中的自身发热量， 起到了给光伏电池片降温的效果， 从而显著提高了系统的发电量和发电效率， 系统产生的直流电能通过逆变器转 换为交流电能直接供给用电负载使用或并入国家电网使用， 还可以将电能储存 在蓄电池中随吋随地取用。 整套系统可以实现电能的自给自足， 白天的发电量 足以供给系统内耗电设备全天的使用， 多余电量用于储存或并网。
