摘要
介绍了两种新型无溶液泵和精馏装置的氨水吸收式制冷空调系统(无回热式和回热式)。首先对两系统的结构特点和循环过程进行了阐述,然后在不同发生器溶液存留倍数下对两系统进行了热力计算分析比较,然后对两系统进行了(火用)计算分析比较。经分析,在理想情况下无回热式系统的热力系数为0.249,总体(火用)效率为0.111;回热式系统的热力系数为0.454,总体效率为0.202。
Two different novel ammonia-water absorption refrigeration （AAR） air conditioning systems without solution pump and distillation equipment were presented, one with solution heat exchanger and the other without. The structure and circulation characteristics of the two systems were illustrate at first. Then the thermodynamic characteristics were calculated under different solution reservation of generator β. Exergy analysis was evaluated at last. The results show that the system with solution heat exchanger has higher thermodynamic and exgery coefficients but more complex compared with the system without it. Under ideal condition （β = 0）, coefficient of performance of the system with solution heat exchanger was 0.454 , and the overall exergy coefficient was 0. 202, while those of the system without solution heat exchanger were 0. 249 and 0.111.
