Description
一种溶液除湿蒸发冷却制冷机组
技术领域
[0001]本发明公开了一种溶液除湿蒸发冷却制冷机组，用于空调制冷机组选择领域。
背景技术
[0002]建筑能耗占社会总能耗的6〇%，而空调能耗又占建筑能耗的50%以上。空调能耗包 括制冷能耗和供热能耗。制冷能耗分制冷机组能耗、冷冻循环水栗能耗、冷却循环水泵能 耗，而制冷机组能耗占据了制冷能耗的一半以上。很多设计师在建筑空调冷源选择时，绝大 部分会考虑电动蒸气压缩制冷、直燃式吸收式制冷两种方式，电动蒸汽压缩式制冷靠电来 驱动，直燃式吸收式制冷机组靠热来驱动，这两种制冷方式的机组能耗都很大。
[0003]本发明一种溶液除湿蒸发冷却制冷机组，利用溶液除湿，降低空气的含湿量，将含 湿量低于4g/kg的冷空气送入闭式冷却塔，与冷冻回水接触而进行热湿交换过程，这种冷却 方式最大限度可使冷却水的温度降低到空气的湿球温度。举例：当空气温度为30。(：，含湿量 为4g/kg时，所对应的湿球温度为13 • 5°C ;当空气温度为35。(：，含湿量为4g/kg时，所对应的 湿球温度为I6 • 5°C。当建筑空调形式采用温湿度独立控制系统时，冷冻水的供水温度可提 高至18〜20°C，而本发明溶液除湿蒸发冷却制冷机组可产生18。(：以下的冷冻水，完全能够满 足温湿度独立控制系统中冷冻水温度的要求。
[0004]本发明一种溶液除湿蒸发冷却制冷机组，其功耗包括除湿溶液的再生能耗、溶液 泵能耗、冷冻水泵能耗，比传统电动蒸气压缩制冷机组和直燃式吸收式制冷机组耗能低，具 有更好的热经济性;因制冷空调一般发生在夏季，而夏季的太阳能一般比较充足，可充分利 用太阳能作为本发明一种溶液除湿蒸发冷却制冷机组的驱动热源，既充分利用了可再生能 源，又减低了制冷能耗，一举两得。尤其是对于新疆这种空气比较干燥同时太阳能资源又非 常丰富的地区，该系统具有良好的推广价值，夏季基本可实现免费太阳能资源供冷。
发明内容
[0005]本发明针对传统电动蒸气压缩制冷机组和直燃式吸收式制冷机组耗能高、维修检 测困难等缺点，提供了一种溶液除湿蒸发冷却制冷机组，所述制冷机组具备能耗低、维护简 单、安全无污染、可充分利用太阳能资源的特点。
[0006]本发明公开了一种溶液除湿蒸发冷却制冷机组，其包括热源、发生器、溶液除湿系 统、气气换热器、闭式蒸发冷却系统、冷冻水供水系统;所述机组可利用溶液除湿系统对空 气除湿，在换热器中利用排风的冷量进行预降温后，再进入闭式蒸发冷却系统进行蒸发冷 却过程；由于进入闭式冷却塔的空气干球温度低、含湿量低，所以湿球温度低;在闭式蒸发 冷却系统对建筑冷冻水回水降温，再利用冷冻水供水系统将制取的冷冻水输送到建筑房间 内；所述溶液除湿蒸发冷却制冷机组可用于但不限用于温湿度独立控制系统冷源。
