摘要:
本文研究了一种基于溶液除湿,冷凝热分级利用的热湿独立处理空调系统,搭建了冷凝热分级利用逆流型再生过程试验台,并建立逆流型再生器的NTU-Le模型,开展了空气进口温度、溶液进口温度、冷凝热一次利用率及冷凝热分配比对再生过程性能影响的研究. 数值模拟结果表明在冷凝总热量相同的情况下,随着冷凝热一次利用率的增加,再生过程的再生量和再生热效率都不断升高. 在冷凝热一次利用率φ从0增加至1的过程中,随着冷凝总热量的增加,再生量和再生热效率的增幅不断增加. 冷凝热加热空气的热量Qa相同,改变冷凝热加热溶液的热量Qs时,再生量与再生热效率均随冷凝热分配比的升高而不断上升,但是如果溶液温度过高对于溶液的再生过程是不利的. 因此选择合适的溶液再生温度来达到较好的再生效果.
Abstract:
In this paper,a system is studied which treats heat and humidity independently in grade utilization of condensation heat based on solution desiccant. A test bench is set up for a counter flow regeneration process with graded utilization of condensation heat,which simulates secondary utilization of condensation heat through heating air,and establishes the NTU-Le model of the counter flow regenerator. Thus theoretical and experimental studies of the effects of graded condensation heat utilization on regeneration process are carried out. Results show that in the case of the equality of total condensation heat in regeneration process,along with the increase of the ratio of primary utilization of condensation heat and primary utilization of condensation heat,the regeneration rate and regenerative heat efficiency in regeneration process both increase. In the growth progress of primary condensing heat utilization ratio variable φ from 0 to 1,the growth range of regeneration rate and regenerative heat efficiency rises continuously along with the increase of total condensation heat. When Qa,the quantity of condensing heat to heat the air maintains constant,and Qs,the quantity of condensing heat to heat the solution is changed,regeneration amount and regenerative heat efficiency reach a peak respectively. Thus considering that,an appropriate temperature of solution regeneration must be chosen synthetically to achieve better results of regeneration.
