溶液调湿空调冬季加湿特性实验

摘要

The performance of liquid desiccant air-conditioning system was improved by studying the humidity-humidifying characteristics of the humidified air conditioner. The experimental test was carried out to reduce the performance of liquid desiccant air conditioning in winter. The effects of inlet parameters and air inlet parameters on humidification performance of air conditioners were analyzed. And then the humidification performance was evaluated by humidifying amount and humidification efficiency. The results showed that: Humidifing efficiency and Humidifing amount increased with the flow of liquid and Humidifing amount of the inlet air; they decreases with the increased of the Humidifing amount of air and the concentration of inlet liquid. The increase of inlet air flow makes the Humidifing amount increase and the Humidifing efficiency decreases. Therefore, it can be concluded that increasing the flow of liquild and the Humidifing amount of inlet air temperature can improve the performance of liquid desiccant air-conditioning system.%目的 研究溶液调湿空调冬季加湿特性, 改善空调系统冬季加湿性能.方法 搭建溶液调湿空调系统, 在冬季工况下进行实验测试, 分析溶液入口参数、空气入口参数对调湿式空调加湿性能的影响规律;采用加湿量和加湿效率评价指标对其加湿性能进行评价分析.结果 加湿效率和加湿量随着溶液流量和进口空气温度含湿量的增加而增加;加湿效率和加湿量随着空气含湿量和进口溶液质量分数增加而下降;进口空气流量的增加使得加湿量增加而加湿效率减少.结论 适当增加溶液流量和进口空气温度含湿量可以改善溶液调湿空调冬季加湿性能.
