摘要
对以氨-水-氦为工质的扩散-吸收式制冷系统进行理论与试验研究,对系统主要部分建立数学模型,用温度曲线描述系统各参数的变化。试验达到的最好结果为冷冻温度最低达到-18.2℃,冷藏温度最低达到6.8℃。
Sets up the system of diffusion-absorption refrigeration based on ammonia and water as the working fluids together with helium as inert gas. Establishes the academic calulation and experimental investigation. Sets up mathematic modules for the main parts of the system and uses thermal curves to describe the running of the system. The system achieves a no-load cooling temperature of - 17.5 ℃ in freeze room and 6.8℃ in refrigeration room.
