下面结合附图对本发明地热式液体空调装置的最佳实施方式进行详细说明。
参照图 1。 图 1是本发明地热式液体空调装置系统结构原理图。 本发明地热式液体 空调装置包括下文将要详细阐述的地热集热器 1、 换热器 2、 能量提升器 3、 出液泵 4、 回液泵 5和空调器 6。 地热集热器 1的出液管 1 1上装有集热器出液泵 1 2， 以提高集 热器 1内的液体流动速度， 提高热交换效率。 换热器 2可以釆用普通的板式热交换器， 集热器 1的出液管 1 1与换热器 2的输入侧 2 a相连接。
能量提升器 3包括制热回路 3 0和热交换回路 3 8， 制热回路 3 0与普通空调机、 冰箱上采用的制热 （冷） 回路相同。 在制热回路 3 0中填充有用于制热循环的介质 R 2
2。 能量提升器 3包括由压缩机 3 1、 冷凝器 3 2、 贮液器 3 3、 干燥过滤器 3 4、 节 流器 3 5、 蒸发器 3 6和气液分离器 3 7通过管道依次连接而组成的制热回路 3 0和热 交换回路 3 8。 热交换回路 3 8中的与冷凝器 3 2相偶合的热交换回路的出液管 3 2 a与 第一二位四通阀 8的第一接口 8 a相连； 热交换回路 3 8中的与冷凝器 3 2相偶合的热交 换回路的进液管 3 2 b 与第二二位四通阔 9的第一接口 9 a相连， 热交换回路 3 8中的与 蒸发器 3 6相偶合的热交换回路的出液管 3. 6 a与第一二位四通阔 8的第三接口 8 c 相 连； 热交换回路 3 8中的与蒸发器 3 6相偶合的热交换回路的进液管 3 6 b经与下文将要 阐述的余热加热器 8 2的连接管路 8 2 1与第二二位四通阀 9的第三接口 9 C相连。
空调器 6可采用普通的风机盘管组。 空调器 6的进液管 1 0 2经出液泵 4与第一二 位四通阀 8的第二接口 8 b相连； 空调器 6的回液管 1 0 3与第二二位四通阀 9的第四接 口 9 d相连。 在空调器 6的回液管 1 0 3上装有膨胀罐 1 0 3 a， 膨胀罐 1 0 3 a的作用在 于储存热交换回路 3 8中的液体因热膨胀而增加的液体体积。
换热器 2的输出侧 2 b 的进液管 2 2 b通过回液泵 5与第一二位四通阀 8的第四接口 8 d相连接； 换热器 2的输出侧 2 b的出液管 2 2 a经安装在出液管 2 2 a上的节止阀 2 2 c 与第二二位四通阀 9的第二接口 9 b相连。
设置上述二个二位四通阀的目的在于使本发明地热式液体空调装置适用于冬夏二季 使用， 如果只作为冬季取暖， 则可不安装二位四通阀。 此时， 可将热交换回路 3 8中的 与冷凝器 3 2相偶合的热交换回路的出液管 3 2 a经出液泵 4直接与空调器 6的进液管 1 0 2相连； 空调器 6的回液管 1 0 3和与冷凝器 3 2相偶合的热交换回路 3 8的进液管
3 2 b 相连， 与蒸发器 3 6相偶合的热交换回路 3 8的出液管 3 6 a通过回液泵 5直接与 换热器 2的输出侧 2 b的回液管 2 2 b相连， 换热器 2的输出侧 2 b的出液管 2 2 a直接和 与蒸发器 3 6相偶合的热交换回路 3 8的进液管 3 6 b相连。
显然， 每个二位四通阀均可用 4个普通的节止阀按图示的连接方式来代替。
当天气寒冷， 由地热集热器提供的热量不足时， 可在本发明地热式液体空调装置上 加装太阳能集热器 7。 太阳能集热器既可为地热集热器 1提供辅助热源， 又可为居民提 供生活热水。 太阳能集热器 7由太阳能热水器 7 1、 太阳能蓄能器 7 2、 循环水泵 7 3 用管路连接而成。 在太阳能蓄能器 7 2的进、 出口管路上装有进口节止阀 7 4和出口节 止阀 7 5。 在太阳能蓄能器 7 2装有热交换器 7 6。 热交换器 7 6的进、 出口管路 7 6 1、 7 6 2并连在换热器 2的输出侧 2 b 的出液管 2 2 a上。 在进口管路 7 6 1上装有热 交换器进口节止阀 7 6 3， 可根据天气状况将热交换器 7 6并连在出液管 2 2 a上， 作为 辅助热源。
在太阳能热水器 7 1上连接有自来水冷水进水管 7 7和生活热水出水管 7 8， 并在 上面分别安装有自来水管节止阀 7 7 1和生活热水出水管节止阀 7 8 1。
在寒冷地区， 天气特别寒冷时， 当由地热集热器 1和太阳能集热器 7提供的热量仍 然不足时还可在本发明地热式.液体空调装置上加装电热器 8作为辅助能源。 电热水器 8 内装有换能器 8 1， 换能器 8 1同样可以采用板式热交换器结构， 换能器 8 1的进、 出 口管路 8 1 1 , 8 1 2并连在换热器 2的输出侧 2 b 的出液管 2 2 a上。 在换能器 8 1的 进口管路 8 1 1上装有换能器进口节止阀 8 1 3。 在使用换能器 8 1时， 也可将出液管 节止阀 2 2 c 关闭。 在春秋二季地热式液体空调装置不运行时， 可利用电加热器加热生活 热水。 电加热器 8上装有自来水进水管 8 3和生活热水出水管 8 4。 在电热水器 8内还. 可装有余热加热器 8 2。 余热加热器 8 2的作用在于冬夏二季可利用本发明地热式液体 空调装置的余热加热电热水器中的水， 达到省电并提供生活热水的目的， 在余热加热器 8 2的进口管路 8 2 1上装有节止阀 8 2 3， 不使用余热加热器 8 2时， 可关闭节止阔 8 2 1 ο
参看图 2〜图 4。 图 2〜图 4是本发明地热式液体空调装置采用的地热蓄能器结构 示意图。 蓄能器可制成圆筒式方式， 它包括蓄能体 1 1、 置于蓄能体 1 1内呈交错堆放 的若干层充有相变物质， 如水、 甘油、 盐水或乙醇的蓄能筒 1 2、 置于上层蓄能筒之上 的具有均布通孔的上均流板 1 3和置于下层蓄能筒之下的具有均布琅孔的支撑板 1 4， 且上均流板 1 3和蓄能体 1 1的上壁之间设有液体进口 1 5， 支撑板 1 4和蓄能体 1 1 的下壁之间形成液体出口 1 6。 蓄能体 1 1的外壁上设有若干个呈米字形排列的散热翅 片 1 8 (见图 2 )。 每个蓄能筒 1 2的两端具有在蓄能筒之间形成液体流动缝隙的凸肩 1 7 , 其中蓄能筒 1 2可由高强耐腐蚀的塑料制成。 凸肩 1 7使蓄能筒 1 2之间产生缝隙， 从而保证液体绕着蓄能筒流动 （见图 4 )。 在流动过程中液体把能量传递给蓄能筒储存起 来。 在液体需要能量时， 通过液体围绕蓄能筒流动， 蓄能筒把能量又传递给液体。, '从而 使蓄能筒达到储存和释放能量的目的。
蓄能器置于地下， 因为地下是一个温度变化不大的恒温带。 也就是俗称的冬暖夏凉 带。 蓄能器置于地下， 除蓄能器内流动液体与蓄能筒之间的换热外， 还具有蓄能器和地 下恒温带的换热。 夏天把冷传给蓄能器， 冬天把热传给蓄能器。
蓄能器另一重要特点是相变蓄能。 以水为例， 水的相变温度为 0°C, 水在液态时 lm3 水温度升高或降低 1 °C需能量 lkWh/°Cm3。 在发生相变时， （TC的水变成 0 Ό的冰需能 量 4 8. 4 kwh/ra3， 也就是水在 0 °C发生相变时， 1 m3水可提供的能量为 4 8. 4 kwh/m
3
在冬季埋入地下的蓄能器与地下温度 1 (re基本一致。 现在计算一下蓄能器储存的 能量。 假设蓄能器中流动液体为 lm3, 蓄能筒内液体为 2m3， 液体体积为 2 + l = 3m3。 降低到 0 °C的显能为 3m3X 1 kwh/Om3 X 1 0 °C= 3 0 kwh。 蓄能筒内液体发生相变时蓄 能为 2 m3X 4 8. 4 kwh/m3 = 9 6. 8 kwh。 蓄能器共蓄能 3 0 + 9 6. 8 = 1 2 6. 8 kwh。 如液体空调器每小时需能为 1 0 KW， 蓄能器可供能量时间为： 1 2 6. 8kwh/
1 0 KW= 1 2. 6 8h， 也就是蓄能器在绝热状态下可提供液体空调器所需能量为 1
2. 6 8h。
夏季地下温度为 1 5 °C， 空调器往室外散热温度为 5 0 °C， 温差为 5 0 V- 1 5 °C = 3 5 V, 冷却蓄能共 1 kwh/°Cm3 X 3 5 °CX 3 m3= 1 0 5 kwh， 每小时耗能 1 0 kw， 可 解决供冷时间为 1 0 5kwh/ 1 Okw= 1 0. 5h， 这是绝热状态下的情况。 如果考虑到 地下恒温带与蓄能器的换热实际值远远大于此值。
地热蓄能器因其体积较大， 适用于居住分散， 空间场地较大的建筑使用。
参照图 5。 图 5是本发明地热式液体空调装置采用的地热集热管的结构示意图。 图 中绘制出了二个地热集热管 1 0 0和 1 0 0 ' 相互串接的结构示意图。 以地热集热管 1. 0 0为例， 集热管 1 0 0由共轴线安装在一起的外换热筒 1 0 1， 位于外换热筒 1 0 1 内的蓄能筒 1 0 2， 位于蓄能筒 1 0 2内的出液管 1 0 3和连接在外换热筒 1 0 1顶部 的进液管 1 0 4组成。 蓄能筒 1 0 2可用几枚固定片 （图中未示出） 焊接在外换热筒 1
0 1内。 出液管 1 0 3可直接焊接在蓄能筒 1 0 2的上、 下壁上。 地热集热管 1 0 0的 出液管 1 0 3与地热集热管 1 0 0， 的进液管 1 0 4 ' 相连接， 地热集热管 1 0 0， 的 出液管 1 Q 3 ' 可与下一个地热集热管 （图中未示出） 的进液管相连接， 如此可根据需 要将多个地热集热管串接在一起成为一组集热管组。
参照图 6。 图 6是本发明地热式液体空调装置采用的由三组集热管组串联构成的地 热集热器的结构示意图。 第一.地热集热管组 1 0 0 G, 假设由 8根地热集热管组成 （见 图 1 )， 每根地热集热管的长度为 6 m; 第二地热集热管组 2 0 0 G假设由 1 2根地热集 热管组成 （见图 1 )， 每根地热集热管的长度为 4 m， 第三地热集热管组 3 0 0 G假设由
1 6根地热集热管组成 （见图 1 )， 每根地热集热管的长度为 2 m。 最后一组集热管组的 出水管与地热集热器的总出液管 1 1相接。 在出液管 1 1的管路上， 在出液泵 1 2前面 装有节止阀 1 3， 在出液泵 1 2的后面装有节止阀 1 4 , 以便修理更换出液泵 1 2时使 用。 地热集热管组 1 0 0 G、 2 0 0 G和 3 0 0 G均竖直埋入 1 0深的地下， 以便由低 到高分段提取土壤内的热量， 最后达到我们所需要的温度。 例如将 7 Ό的水经第一集热 管组 1 0 0 G使其温度提高至 8 Ό, 经第二集热管组 2 0 0 G使水温提高至 1 0 V, 经 第三集热管组 3 0 0 G使水温提高至 1 2 °C。 1 2 °C的水经换热器 2将热量传递给换热 器的输出侧 2 b后。 隆至 7 °C再回流至第一集热管组 1 Q 0 G， 再经第二、 第三集热管组 2 0 0 G、 3 0 0 G再升温， 如此循环不已。 地热集热管的外换筒 1 0 1的外径例如可 选为 1 0 0 ram, 蓄能筒 1 0 2的外径可选为 8 0 ram,出水管 1 0 3的外径可选为 2 5腿。 图 6中左侧给出了地层下面的温度与深度之间的变化关系， 地热集热管的优点是体积小， 可见缝插针， 适用于住房密集空间场地下的地方使用。
本发明地热式液体空调装置， 其热交换回路和地热集热器内可用防冻液作为工作介 质。
下面结合附图描述一下本发明地热式液体空调装置的工作过程。 参照图 1。 图 1中 第一二位四通阀 8和第二二位四通阀 9中涂黑的部分表示关闭的流道。 在冬季， 如上文 所述， 地热集热器 1将集热器内的水升温至 1 2 。C , 出液泵 1 2通过阀 1 3 、 1 4将 1
2 Ό的水送到换热器 2的输入侧 2 a， 通过换热器 2将热量传递给换热器输出侧 2 b。 输 出侧 2 b 内的 1 1 Ό的水经节止阔 2 2 c , 第二二位四通阀 9、 管道 8 2 1 、 3 6 b送入 与蒸发器 3 6相偶合的热交换回路 3 8。 在蒸发器 3 6内进行热交换， 将热量传递给蒸 发器 3 6。 经热交换后的液体经出液管 3 6 a，第一二位四通阀 8、 回液泵 5、 换热器 2 的回液管 2 2 b流回至换热器 2。 与此同时， 蒸发器 3 6中的工质 R 2 2通过蒸发器 3 6 的作用被转换为低温低压气体送入分离器 3 7 , 在气液分离器 3 7中经气液分离后被送 入压缩机 3 1。 低压低温气体通过压缩机变为高温高压气体并被送至冷凝器 3 2。 在冷 凝器 3 2中， 由压縮机 3 1送出的高温高压气体和与冷凝器 3 2相偶合的热交换回路 3
8内的工作介质进行热交换， 热交换后， 被加热的液体工作介质经出液管 3 2 a, 第一二 位四通阀 8， 出液泵 4及空调器 6的进液管 1 0 2流入空调器给室内空气升温。 经空调 器散热后的液体工作介质通过空调器的回液管 1 0 3， 第二二位四通阀 9 , 进液管 3 2 b 流回至与冷凝器 3 2相偶合的热交换回路 3 8， 完成工作循环。
在夏季制冷时， 应将该图中第一二位四通阀 8和第二二位四通阀 9换向。 即将第一、 第二二位四通阀涂黑的流道与空白的流道交换， 启闭部分正好与图中所示的部分相反。 其中， 第一二位四通阀 8接通与蒸发器 3 6相偶合的热交换回路 3 8的出液管 3 6 a和空 调器的进液管 1 0 2， 并接通与冷凝器 3 2相偶合的热交换回路 3 8的出液管 3 2 a和换 热器 2的回液管 2 2 b ; 同时， 第二二位四通陶 9接通与蒸发器 3 6相偶合的热交换回路
3 8的进液管 3 6 b和空调器 6的回液管 1 0 3， 并接通与冷凝器 3 2相偶合的热交换回 路 3 8的进液管 3 2 b 和换热器 2的出液管 2 2 a, 使与蒸发器 3 6相偶合的热交换回路 3 8内的低温工作介质与空调器相连， 从而实现向室内提供冷气。
本发明地热式液体空调器的工作通用采用间歇式工作，例如工作 1小时， 停止 2小时， 或工作半小时， 停止 1小时， 以便使地热集热器储存足够的能量。 jl业实用性
' 本发明地热式液体空调装置 , 将地下所含的大量的低位的地下冷热源用地热集热器收 集储存起来， 并通过液体将地热集热器的低位冷热能输送到能量提升器， 然后再通过液 体把提升后的高位冷热能输送到冷热需要处。 其工作时不产生任何有毒有害物质， 无公 害， 无污染， 且价格便宜。 用于建筑物室内采暖或致冷， 也可用其提供生活用水。
