本文通过对低压部分为吸收式、高压部分为压缩式的氨水吸收压缩式制冷系统的试验研究和理论分析,证明了该系统实际运行的可行性,建立了系统的数学模型,并分析了制冷温度、冷却水温、热源温度和中间压力对系统性能的影响,可以看出中间压力是其中较重要的因素。本文给出了最佳中间压力分别与冷却水温、制冷温度和热源温度的关系,并将该系统的主要指标与吸收式系统和压缩式系统作了比较。
In this paper, the experimental research and theoretical analysis of the compression-type ammonia absorption compression refrigeration system in which the low-pressure part is the absorption type and the high-pressure part are carried out. The feasibility of the system is proved, the mathematical model of the system is established and the refrigeration temperature , Cooling water temperature, heat source temperature and intermediate pressure on the system performance, we can see that the intermediate pressure is one of the more important factors. In this paper, the relationship between the optimum intermediate pressure and the cooling water temperature, the cooling temperature and the heat source temperature are given respectively. The main indexes of the system are compared with the absorption system and the compression system.
