热源塔热泵夏季制冷运行时, 低温低压的制冷剂气体从气液分离器中被压縮机吸 入压縮后变成高温高压的过热蒸气排出, 制冷剂经过四通阀进入设置在复式热源塔塔 体内的填料式盘管换热器中, 制冷剂在填料式盘管换热器中与水换热, 放出热量, 冷 凝成液体, 从填料式盘管换热器出来后, 再依次经过第二单向阀、 第二电磁阀 (此时 第一电磁阀关闭) 进入第二换热器中, 液体制冷剂与冷却水换热, 制冷剂放出热量, 实现进一步过冷, 制冷剂从第二换热器流出后, 依次经过储液器、 过滤器、 电子膨胀 阀后被节流成低温低压的气液两相, 再经过第三单向阀进入第一换热器, 制冷剂在第 一换热器中吸热蒸发, 制取冷冻水, 制冷剂完全蒸发后从第一换热器出来经过四通阀 进入气液分离器, 然后再次被吸入压縮机, 如此循环, 制取冷冻水。 此时溶液回路中 充灌着冷却水, 在溶液回路中, 集液槽中的冷却水从复式热源塔塔体第二输出端出来 后被溶液泵吸入, 经过溶液泵加压后, 冷却水进入电动三通调节阀, 冷却水在电动三 通调节阀中被分成两路, 一路从电动三通调节阀第一输出端流出进入第一布液装置, 另外一路从电动三通调节阀第二输出端流出进入第二换热器中, 冷却水在第二换热器 中与液体制冷剂进行换热, 吸收热量, 温度升高后, 从第二换热器中流出进入第二布 液装置, 冷却水被均匀喷淋到填料中, 冷却水在填料中与空气进行热质交换, 部分冷 却水蒸发, 余下冷却水温度降低, 冷却水从填料中流出后, 与从第一布液装置中均匀 喷出冷却水混合一道进入到填料式盘管换热器, 在其中与空气及填料式盘管换热器中 的制冷剂进行换热, 部分冷却水蒸发, 将填料式盘管换热器的制冷剂冷凝成液体, 冷 却水从填料式盘管换热器出来后落入集液槽中, 然后再次从复式热源塔塔体第二输出 端流出, 如此循环。 空气回路中, 空气从复式热源塔塔体下部进入复式热源塔, 然后 首先进入填料式盘管换热器, 在填料式盘管换热器中与冷却水进行热质交换, 部分冷 却水蒸发, 空气中含湿量增加, 空气从填料式盘管换热器出来后, 进入填料中, 空气 进一步与填料中的冷却水进行传热传质, 空气的温度和含湿量进一步增加, 空气从填 料中出来后经过防飘液装置, 空气中液体小水滴被拦截, 然后空气从防飘液装置出来 后被风机吸入, 加压后排出复式热源塔。 冷热水回路中冷冻水从机组的冷热水回水端 进入第一换热器中, 冷冻水在其中与制冷剂换热, 温度降低, 冷冻水从第一换热器出 来后由机组的冷热水供水端流出机组。
热源塔热泵冬季制热运行分两种模式, 制热运行模式一: 热源塔热泵冬季制热运 行, 当空气中湿度较小, 在复式热源塔中的空气中的水蒸汽分压力小于或等于溶液表 面的水蒸汽分压力时, 即水分是从溶液进入到空气中时, 气液分离器中低温低压的制 冷剂气体被压縮机吸入、 压縮后排出, 通过四通阀进入第一换热器, 制冷剂在第一换 热器中放出热量, 自身冷凝成液体, 制取供热热水, 然后通过第一单向阀、 第一电磁 阀 (此时第二电磁阀关闭) 后依次经过储液器、 过滤器、 电子膨胀阀后, 制冷剂被节 流降压, 以气液两相通过第四单向阀进入填料式盘管换热器中, 制冷剂在填料式盘管 换热器中与溶液换热, 制冷剂蒸发吸热, 制冷剂完全蒸发后从填料式盘管换热器出来 流经四通阀进入气液分离器, 最后再次被压縮机吸入, 从而完成制热循环, 制取供热 热水。 此时溶液回路中充灌着溶液。 在溶液回路中, 集液槽中溶液从复式热源塔塔体 第二输出端流出后被溶液泵吸入, 经过溶液泵加压后进入电动三通调节阀, 溶液全部 从电动三通调节阀第一输出端流出进入第一布液装置 (此时电动三通调节阀第二输出 端关闭,流出流量为零),在第一布液装置中,溶液被均匀喷淋到填料式盘管换热器中, 溶液以均匀液膜或液滴形式向下流动, 与空气回路中的空气进行传热传质, 溶液吸收 热量, 同时溶液也与填料式盘管换热器管内的制冷剂进行换热, 将热量传递给填料式 盘管换热器中的制冷剂, 溶液从填料式盘管换热器流出后, 落入集液槽中, 然后溶液 再次从复式热源塔塔体第二输出端流出。
空气回路中, 空气从复式热源塔塔体下部进入复式热源塔, 然后首先进入填料式 盘管换热器, 在填料式盘管换热器中与溶液进行热质交换, 空气温度降低, 含湿量增 加, 空气从填料式盘管换热器出来后, 进入填料中, 因第二布液装置没有溶液流出, 空气将直接通过填料进入防飘液装置, 空气中溶液小液滴被拦截, 然后空气从防飘液 装置出来后被风机吸入, 加压后排出复式热源塔。 冷热水回路中热水从机组的冷热水 回水端进入第一换热器中, 热水在其中与制冷剂换热, 温度升高后, 从第一换热器出 来, 由机组的冷热水供水端流出机组。
制热运行模式二: 当空气中湿度较大, 在复式热源塔中的空气中的水蒸汽分压力 大于溶液表面的水蒸汽分压力时, 即水分是从空气进入到溶液中时, 制冷剂回路中, 气液分离器中低温低压的制冷剂气体被压縮机吸入、 压縮后排出, 通过四通阀进入第 一换热器, 制冷剂在第一换热器中放出热量, 冷凝成液体, 制取供热热水, 制冷剂从 第一换热器中出来后, 通过第一单向阀、 第二电磁阀 (此时第一电磁阀关闭) 后进入 第二换热器, 在第二换热器中与溶液进行换热, 制冷剂放出热量, 进一步过冷, 从第 二换热器出来后依次经过储液器、 过滤器、 电子膨胀阀, 制冷剂被节流降压, 以气液 两相通过第四单向阀进入填料式盘管换热器, 在填料式盘管换热器中与溶液换热, 进 行蒸发吸热,制冷剂完全蒸发后从填料式盘管换热器出来流经四通阀进入气液分离器, 最后再次被压縮机吸入, 重新被压縮参与循环。 此时溶液回路中充灌着溶液, 集液槽 中溶液从复式热源塔塔体第二输出端出来后进入溶液泵, 经过溶液泵加压后进入电动 三通调节阀, 溶液在电动三通调节阀中被分成两路, 一路从电动三通调节阀第一输出 端流出进入第一布液装置, 另外一路从电动三通调节阀第二输出端流出进入第二换热 器中, 溶液在第二换热器中与液体制冷剂进行换热, 吸收热量, 温度升高后, 从第二 换热器中流出进入第二布液装置, 溶液被均匀喷淋到填料中, 溶液在填料中与空气进 行热质交换, 因此时溶液温度较高, 溶液中的水蒸汽分压力大于空气中水蒸汽分压力, 溶液中水分进入空气中, 溶液浓度将提高, 实现溶液再生, 溶液从填料中流出后, 与 从第一布液装置中均匀布撒的溶液混合后一道进入到填料式盘管换热器, 溶液在其中 与空气进行换热, 溶液从空气中吸收热量, 温度升高, 同时空气中的水蒸汽分压力大 于溶液表面的水蒸汽分压力, 空气中水分进入溶液, 溶液吸收这部分潜热, 溶液浓度 将降低。 与此同时, 溶液也与填料式盘管换热器中的制冷剂换热, 溶液放出热量, 使 制冷剂吸热蒸发, 溶液的温度将降低。溶液从填料式盘管换热器出来后落入集液槽中, 然后再次从复式热源塔塔体第二输出端流出, 如此循环。
空气回路中, 空气从复式热源塔塔体下部进入复式热源塔, 然后首先进入填料式 盘管换热器, 在填料式盘管换热器中与溶液进行热质交换, 因空气中的水蒸汽分压力 大于溶液表面的水蒸汽分压力, 空气温度降低同时含湿量减少, 空气从填料式盘管换 热器出来后, 进入填料中, 此时填料中的溶液温度较高, 而空气经过填料式盘管换热 器后温度降低, 含湿量减少, 因此, 填料中溶液的表面水蒸汽分压力远大于空气中的 水蒸汽分压力, 此时溶液中的水分将大量进入空气, 溶液的浓度得到提高, 空气的温 度和含湿量将大幅上升, 空气从填料中出来后经过防飘液装置, 空气中溶液小液滴被 拦截, 然后空气从防飘液装置出来后被风机吸入, 加压后排出复式热源塔。
冷热水回路中供热热水从机组的冷热水回水端进入第一换热器中, 热水在其中与 制冷剂换热, 温度升高后, 从第一换热器出来, 由机组的冷热水供水端流出机组。
在***制热运行模式二过程中, 1 )溶液再生利用的是液体制冷剂冷却实现过冷所 放出的热量, 通过控制电动三通调节阀, 实现对分别进入第一布液装置和第二布液装 置的溶液流量进行调节, 即调节进入填料中再生的溶液量, 从而实现对复式热源塔中 溶液浓度的控制; 2)利用填料与填料式盘管换热器在空气回路上串联, 实现了空气通 过填料式盘管换热器为热泵***提供低位热源的同时, 利用从填料式盘管换热器出来 的空气的低温和低湿度, 为溶液再生提供好的环境, 实现溶液的更好再生, 使***获 得高效制热效率的同时, 具有最佳的溶液再生性能, 保持***运行安全可靠。

热源塔热泵夏季制冷运行时,低温低压的制冷剂气体从气液分离器 14中被压縮机 1 吸入压縮后变成高温高压的过热蒸气排出, 制冷剂经过四通阀 2进入设置在复式热 源塔塔体 24内的填料式盘管换热器 17中,制冷剂在填料式盘管换热器 17中与水换热, 放出热量, 冷凝成液体, 从填料式盘管换热器 17出来后, 再依次经过第二单向阀 5、 第二电磁阀 7 (此时第一电磁阀 6关闭) 进入第二换热器 8中, 液体制冷剂与冷却水 换热, 制冷剂放出热量, 实现进一步过冷, 制冷剂从第二换热器 8流出后, 依次经过 储液器 9、 过滤器 10、 电子膨胀阀 11后被节流成低温低压的气液两相, 再经过第三单 向阀 12进入第一换热器 3, 制冷剂在第一换热器 3中吸热蒸发, 制取冷冻水, 制冷剂 完全蒸发后从第一换热器 3出来经过四通阀 2进入气液分离器 14, 然后再次被吸入压 縮机 1, 如此循环, 制取冷冻水。 此时溶液回路中充灌着冷却水, 在溶液回路中, 集 液槽 16中的冷却水从复式热源塔塔体第二输出端 24e出来后被溶液泵 23吸入, 经过 溶液泵 23加压后, 冷却水进入电动三通调节阀 15, 冷却水在电动三通调节阀 15中被 分成两路, 一路从电动三通调节阀第一输出端 15b流出进入第一布液装置 18, 另外一 路从电动三通调节阀第二输出端 15c流出进入第二换热器 8中,冷却水在第二换热器 8 中与液体制冷剂进行换热, 吸收热量, 温度升高后, 从第二换热器 8中流出进入第二 布液装置 20, 冷却水被均匀喷淋到填料 19中, 冷却水在填料 19中与空气进行热质交 换, 部分冷却水蒸发, 余下冷却水温度降低, 冷却水从填料 19中流出后, 与从第一布 液装置 18 中均匀喷出冷却水混合一道进入到填料式盘管换热器 17, 在其中与空气及 填料式盘管换热器 17 中的制冷剂进行换热, 部分冷却水蒸发, 将填料式盘管换热器 17的制冷剂冷凝成液体, 冷却水从填料式盘管换热器 17出来后落入集液槽 16中, 然 后再次从复式热源塔塔体第二输出端 24e流出, 如此循环。 空气回路中, 空气从复式 热源塔塔体 24下部进入复式热源塔, 然后首先进入填料式盘管换热器 17, 在填料式 盘管换热器 17中与冷却水进行热质交换, 部分冷却水蒸发, 空气中含湿量增加, 空气 从填料式盘管换热器 17出来后, 进入填料 19中, 空气进一步与填料 19中的冷却水进 行传热传质, 空气的温度和含湿量进一步增加, 空气从填料 19中出来后经过防飘液装 置 21, 空气中液体小水滴被拦截, 然后空气从防飘液装置 21出来后被风机 22吸入, 加压后排出复式热源塔。 冷热水回路中冷冻水从机组的冷热水回水端进入第一换热器 3 中, 冷冻水在其中与制冷剂换热, 温度降低, 冷冻水从第一换热器 3 出来后由机组 的冷热水供水端流出机组。
热源塔热泵冬季制热运行分两种模式, 制热运行模式一: 热源塔热泵冬季制热运 行, 当空气中湿度较小, 在复式热源塔中的空气中的水蒸汽分压力小于或等于溶液表 面的水蒸汽分压力时, 即水分是从溶液进入到空气中时, 气液分离器 14中低温低压的 制冷剂气体被压縮机 1吸入、 压縮后排出, 通过四通阀 2进入第一换热器 3, 制冷剂 在第一换热器 3中放出热量, 自身冷凝成液体, 制取供热热水, 然后通过第一单向阀 4、 第一电磁阀 6 (此时第二电磁阀 7关闭) 后依次经过储液器 9、 过滤器 10、 电子膨 胀阀 11后, 制冷剂被节流降压, 以气液两相通过第四单向阀 13进入填料式盘管换热 器 17中, 制冷剂在填料式盘管换热器 17中与溶液换热, 制冷剂蒸发吸热, 制冷剂完 全蒸发后从填料式盘管换热器 17出来流经四通阀 2进入气液分离器 14, 最后再次被 压縮机 1吸入, 从而完成制热循环, 制取供热热水。 此时溶液回路中充灌着溶液。 在 溶液回路中, 集液槽 16中溶液从复式热源塔塔体第二输出端 24e流出后被溶液泵 23 吸入, 经过溶液泵 23加压后进入电动三通调节阀 15, 溶液全部从电动三通调节阀第 一输出端 15b流出进入第一布液装置 18 (此时电动三通调节阀第二输出端 15c关闭, 流出流量为零), 在第一布液装置 18中, 溶液被均匀喷淋到填料式盘管换热器 17中, 溶液以均匀液膜或液滴形式向下流动, 与空气回路中的空气进行传热传质, 溶液吸收 热量, 同时溶液也与填料式盘管换热器 17管内的制冷剂进行换热, 将热量传递给填料 式盘管换热器 17中的制冷剂,溶液从填料式盘管换热器 17流出后,落入集液槽 16中, 然后溶液再次从复式热源塔塔体第二输出端 24e流出。
空气回路中, 空气从复式热源塔塔体 24下部进入复式热源塔, 然后首先进入填料 式盘管换热器 17, 在填料式盘管换热器 17 中与溶液进行热质交换, 空气温度降低, 含湿量增加, 空气从填料式盘管换热器 17出来后, 进入填料 19中, 因第二布液装置 20没有溶液流出, 空气将直接通过填料 19进入防飘液装置 21, 空气中溶液小液滴被 拦截, 然后空气从防飘液装置 21出来后被风机 22吸入, 加压后排出复式热源塔。 冷 热水回路中热水从机组的冷热水回水端进入第一换热器 3中, 热水在其中与制冷剂换 热, 温度升高后, 从第一换热器 3出来, 由机组的冷热水供水端流出机组。
制热运行模式二: 当空气中湿度较大, 在复式热源塔中的空气中的水蒸汽分压力 大于溶液表面的水蒸汽分压力时, 即水分是从空气进入到溶液中时, 制冷剂回路中, 气液分离器 14中低温低压的制冷剂气体被压縮机 1吸入、 压縮后排出, 通过四通阀 2 进入第一换热器 3, 制冷剂在第一换热器 3中放出热量, 冷凝成液体, 制取供热热水, 制冷剂从第一换热器 3中出来后, 通过第一单向阀 4、 第二电磁阀 7 (此时第一电磁阀 6关闭) 后进入第二换热器 8, 在第二换热器 8中与溶液进行换热, 制冷剂放出热量, 进一步过冷, 从第二换热器 8出来后依次经过储液器 9、 过滤器 10、 电子膨胀阀 11, 制冷剂被节流降压, 以气液两相通过第四单向阀 13进入填料式盘管换热器 17, 在填 料式盘管换热器 17中与溶液换热, 进行蒸发吸热, 制冷剂完全蒸发后从填料式盘管换 热器 17出来流经四通阀 2进入气液分离器 14, 最后再次被压縮机 1吸入, 重新被压 縮参与循环。此时溶液回路中充灌着溶液, 集液槽 16中溶液从复式热源塔塔体第二输 出端 24e出来后进入溶液泵 23, 经过溶液泵 23加压后进入电动三通调节阀 15, 溶液 在电动三通调节阀 15中被分成两路,一路从电动三通调节阀第一输出端 15b流出进入 第一布液装置 18, 另外一路从电动三通调节阀第二输出端 15c流出进入第二换热器 8 中, 溶液在第二换热器 8中与液体制冷剂进行换热, 吸收热量, 温度升高后, 从第二 换热器 8中流出进入第二布液装置 20, 溶液被均匀喷淋到填料 19中, 溶液在填料 19 中与空气进行热质交换, 因此时溶液温度较高, 溶液中的水蒸汽分压力大于空气中水 蒸汽分压力, 溶液中水分进入空气中, 溶液浓度将提高, 实现溶液再生, 溶液从填料 19中流出后, 与从第一布液装置 18 中均匀布撒的溶液混合后一道进入到填料式盘管 换热器 17, 溶液在其中与空气进行换热, 溶液从空气中吸收热量, 温度升高, 同时空 气中的水蒸汽分压力大于溶液表面的水蒸汽分压力, 空气中水分进入溶液, 溶液吸收 这部分潜热, 溶液浓度将降低。 与此同时, 溶液也与填料式盘管换热器 17中的制冷剂 换热, 溶液放出热量, 使制冷剂吸热蒸发, 溶液的温度将降低。 溶液从填料式盘管换 热器 17出来后落入集液槽 16中,然后再次从复式热源塔塔体第二输出端流出 24e,如 此循环。
空气回路中, 空气从复式热源塔塔体 24下部进入复式热源塔, 然后首先进入填料 式盘管换热器 17, 在填料式盘管换热器 17 中与溶液进行热质交换, 因空气中的水蒸 汽分压力大于溶液表面的水蒸汽分压力, 空气温度降低同时含湿量减少, 空气从填料 式盘管换热器 17出来后, 进入填料 19中, 此时填料 19中的溶液温度较高, 而空气经 过填料式盘管换热器 17后温度降低, 含湿量减少, 因此, 填料 19中溶液的表面水蒸 汽分压力远大于空气中的水蒸汽分压力, 此时溶液中的水分将大量进入空气, 溶液的 浓度得到提高, 空气的温度和含湿量将大幅上升, 空气从填料 19中出来后经过防飘液 装置 21,空气中溶液小液滴被拦截,然后空气从防飘液装置 21出来后被风机 22吸入, 加压后排出复式热源塔。
冷热水回路中供热热水从机组的冷热水回水端进入第一换热器 3中, 热水在其中 与制冷剂换热, 温度升高后, 从第一换热器 3出来, 由机组的冷热水供水端流出机组。
在***制热运行模式二过程中, 1 )溶液再生利用的是液体制冷剂冷却实现过冷所 放出的热量, 通过控制电动三通调节阀 15, 实现对分别进入第一布液装置 18和第二 布液装置 20的溶液流量进行调节, 即调节进入填料 19中再生的溶液量, 从而实现对 复式热源塔中溶液浓度的控制; 2)利用填料 19与填料式盘管换热器 17在空气回路上 串联, 实现了空气通过填料式盘管换热器 17为热泵***提供低位热源的同时, 利用从 填料式盘管换热器 17出来的空气的低温和低湿度, 为溶液再生提供好的环境, 实现溶 液的更好再生, 使***获得高效制热效率的同时, 具有最佳的溶液再生性能, 保持系 统运行安全可靠。
