摘要(Abstract):

提出了一种基于溶液除湿和高温冷水机组的混合式空气调节系统。系统冷源由一个高温冷水机组提供,产生冷水分两部分,其一用来作为除湿器的内冷源,其二结合风机盘管去除室内显热。通过设定一个具体工况,将该混合型空气调节方式与传统的冷冻除湿空气调节方式在能源消耗和经济性方面进行了比较。为了计算方便,设计了一个计算氯化锂水溶液性质的程序。计算结果表明,该系统在运行费用方面较传统方式有一定的优势,能节约38%的费用。
A hybrid air-conditioning system based on liquid desiccant and high-temperature chiller is proposed,in which system the temperature of cooling source is higher than conventional air-conditioning system.The cold water produced by the chiller is made of two parts,one of which works as interior cooling source of the dehumidifier and the other absorbs sensible heat integrated with fan coil.By setting a working condition,the hybrid air-conditioning system is compared with a conventional system in the filed of energy-consuming and economical efficiency.In order to make calculation more calculation more conveniently,a program was designed to calculate the properties of aqueous solution of lithium chloride.The simulative calculation reveals that the bybrid air-conditioning system saves more operating cost than the conventional system by thirty-eight percents.
