【摘要】 提出了采用太阳能、天然气联合驱动的扩散吸收式冰箱空调复合机总体设计方案,对其中相关技术问题进行了论述,重点对扩散吸收式制冷机工质的选择进行了探讨。通过对扩散吸收式系统常用的NH3/H2O,NH3/NaSCN,NH3/LiNO3吸收制冷工质对进行分析比较,认为在综合考虑系统的性能系数、最低制冷温度、溶液结晶、溶液比热和粘度等因素后,以选用LiNO3/NH3/He作为复合机中扩散吸收式制冷机的工质为好。更多还原

【Abstract】 Design of an integrated fridge and air-conditioner with diffusion-absorption refrigeration system driven by natural gas and solar energy was put forward.Technologies involved and process of selecting working fluids for diffusion-absorption refrigeration system were discussed.After a comparison and analysis of system performance of coefficient(COP) and thermodynamic and physical properties such as minimum temperature,crystallization,specific heat and viscosity of solutions of NH3/H2O,NH3/ NaSCN,and NH3/ LiNO3,LiNO3/NH3/He was selected as the working fluid of the diffusion-absorption refrigeration system in the integrated system.更多还原
