基于溶液除湿的辐射空调系统的初步研究

Primary Research on a Radiant Air Condition System Based on Solution Desiccant

针对辐射板空调系统用于高热、高湿地区夏季供冷时辐射板表面结露的问题,提出基于热、湿负荷分开处理的液体除湿辐射空调系统；该系统采用LiCl溶液作为除湿剂,除湿干空气承担空调房间的湿负荷；对除湿后的干空气直接蒸发冷却,使空调回水降温,负担空调房间的热负荷；该系统具有辐射空调节能、舒适的优点,避免了表面结露的问题,同时不需要另外添加冷水机组,节约系统初投资,此外还考虑了能量回收和太阳能的利用。

Presented a new type of air conditioning system- the liquid desiccant radiant air conditioning system, which is based on the independent humidity control method and could prevent dew coagulating on the surface of radiation panels in hot and humid climates. By using this system, the building latent load will be removed by the dry air, which is dehumidified by LiCl-H2O solution. And the cooling load will be removed by the cycling water, which is cooled in the directly evaporation cooling procedure of the desiccated dry air. This new type of system has all the advantages of a radiation air conditioning system, such as energy saving, comfortableness, while it could avoid dew coagulating. What＇s more, this system does not need additional water chilling unit, so it would reduce the preliminary investment. In addition, energy recycling and the use of solar energy are also considered.
