摘要

介绍了一种新型无溶液泵和精馏装置的氨水吸收式制冷空调系统

确定了系统在空调工况运行的基本参数

并针对该系统定义了一个新参数

即发生器溶液存留系数然后对系统热力性能进行了计算分析.分析结果表明:在设定制冷量为1.5 kW时

系统的性能系数可达0.28; 当溶液存留系数由0增加到3时

系统性能系数较初始值降低60%

溶液存留系数对系统性能系数影响显著; 冷剂含水率增加使系统性能系数和制冷量迅速线性递减

当冷剂含水率增加到0.14时

系统丧失制冷能力; 蒸发温度降低或冷凝温度升高都会降低系统的性能系数

二者的影响较为平缓.针对各参数的影响初步探讨了提高系统性能系数的措施.

Abstract

A novel kind of ammonia absorption refrigeration(AAR)system without solution pump and distillation equipment for air conditioning was presented. The basic operation property parameters were selected and a new parameter of solution reservation of generator

β was defined for the special system. Then the thermodynamic characteristics were analyzed by means of boiling temperature

condensation temperature

and water content in refrigerant as well as solution reservation of generator. The results show that coefficient of performance could be up to 0.28 when calculated cooling capacity is set at 1.5 kW

which indicates that the system is feasible in using waste heat and solar energy. When β increases from 0 to 3

the decrease of coefficient of performance would be up to 60%. Water content deteriorates cooling capacity and coefficient of performance significantly

the system could lose cooling capability when the water content is greater then 0.14. Both increasing boiling temperature and reducing condensation temperature could enhance the coefficient of performance. The solution to reducing the influences of these parameters was also discussed.
