氨-盐吸收式制冷循环以其优良的热力性能和简单的结构被认为在空调和冷冻行业的余热回收方面具有潜在的应用前景。本文设计并搭建了一台余热驱动的NH3-NaSCN吸收式制冷系统实验样机，并对其性能进行了评价。为了降低成本和易于制造，原型设计为由常用设备构造。针对排气热源，设计了翅片管发生器。来自排气模拟装置的热源在150°C和350°C之间的温度下供应给发电机。在不同的工况下，如排气温度、冷却水温度、冷冻水温度，进行了不同参数的实验。结果表明，样机的最低蒸发温度降低到-24.56 ° C，制冷量为0.748 ~ 5.60 kW。基于电功率的最大性能系数为17.58，基于电功率和热能的总性能系数在0.351和0.653之间变化。样机在广泛的操作条件下表现出令人满意的性能，表明该系统适用于空调和冷冻应用。该研究为余热驱动氨-盐吸收式制冷系统的优化和应用提供了重要参考。
Excellent thermal performance and simple construction are the most attractive superiorities of ammonia-salt absorption refrigeration cycles, which is considered to be potentially used in waste heat recovery for the air-conditioning and freezing applications. In the present work, an experimental prototype of an exhaust-heat-driven NH3-NaSCN absorption refrigeration system was designed and built to evaluate the performance. The prototype was designed to be constructed by commonly used devices for the purpose of cost reduction and easy manufacture. A finned-tube generator was specially designed for the exhaust-gas heat sources. The heat source from the exhaust simulation unit was supplied to the generator at temperatures between 150°C and 350°C. Experiments with variational operating conditions, such as exhaust-gas temperatures, cooling-water temperatures, chilled-water temperatures, have been conducted for varying parameters. The results showed that the minimum evaporating temperature of the prototype decreased to -24.56°C; the cooling capacity produced by the prototype was ranging from 0.748 kW to 5.60 kW. The maximum coefficient of performance based on electrical power was 17.58, and the overall coefficient of performance based on both electrical power and thermal energy varied between 0.351 and 0.653. The prototype showed satisfactory performance under wide operating conditions, indicating that the system is appropriate for both air-conditioning and freezing applications. The present study provides significant references for the optimization and application of the exhaust-heat-driven ammonia-salt absorption refrigeration systems.
