摘要
二氧化碳具有环保、稳定性好、制取成本低等多种优势,被认为是比较理想的取代当前使用的HCFCs和HFCs的制冷剂.然而,跨临界二氧化碳制冷循环由于高压问题导致循环效率较低,并且冷凝除湿效率低下.为了解决上述问题,论文提出了一种耦合了溶液除湿系统的跨临界二氧化碳压缩式制冷系统,并进行了理论模拟和分析.发现在不同工况下,该系统相比单独的二氧化碳制冷循环系统,效率可以提高10%～80%.表明其拥有广阔的发展潜力和应用前景.
Abstract
CO2 has many advantages,such as environmental friendliness,good stability,and low production cost,and it is considered to be an ideal refrigerant for the next generation.However,the transcritical CO2 refrigeration cycle has a low efficiency due to high pressure issues,and the condensation dehumidification efficiency is poor.To solve these problems,this paper proposes a transcritical CO2 compression refrigeration system coupled with a solution dehumidification system and conducts theoretical simula-tion and analysis.It is found that under different operating conditions,the efficiency of this system can be improved by 10%～80%compared to a standalone CO2 refrigeration cycle system,indicating its broad development potential and application prospects.
