【摘要】：空气湿度处理过程是空调系统的重要组成环节,提高其能效水平是实现空调系统节能运行的重要途径.本文从空调系统的基本排湿任务出发分析了理想排湿过程的处理能效,对比了利用冷凝除湿方法和溶液除湿方法构建的理想排湿过程间的性能差异,结果表明,利用溶液除湿方式可达到更高的理想排湿能效水平.从理想排湿过程出发,分析了实际情况下溶液除湿空气处理过程的特性.在实际处理过程中,空气与溶液间热湿处理过程的损失原因主要包括有限的传热传质能力、流量不匹配和入口参数不匹配等.利用不匹配系数?m刻画了实际溶液除湿过程的不匹配损失特性,并可有效指导实际溶液除湿处理流程的构建.
[Abstract]:The process of air humidity treatment is an important part of air conditioning system, and improving its energy efficiency is an important way to realize the energy saving operation of air conditioning system. Based on the basic dehumidification task of air conditioning system, this paper analyzes the energy efficiency of the ideal dehumidification process, and compares the performance difference between the ideal dehumidification process constructed by condensation dehumidification method and the solution dehumidification method. The method of solution dehumidification can achieve higher energy efficiency of dehumidification. Based on the ideal dehumidification process, the characteristics of solution dehumidification air treatment process are analyzed. In the actual treatment process, the main reasons for the loss of heat and moisture treatment between air and solution include the limited heat and mass transfer capacity, the mismatch of flow rate and the mismatch of inlet parameters, etc. The mismatch loss characteristics of the actual solution dehumidification process are described by using the mismatch coefficient m, which can effectively guide the construction of the actual solution dehumidification process.
