摘要：

This study presents the results of the evaluation of an ammonia/lithium nitrate absorption cooling system. The generator and the absorber are shell and tubes falling film heat exchangers while the rest of the components are compact plate heat exchangers. A parametric study was carried out in order to determine the coefficients of performance and cooling capacities at different operating conditions. Also, an analysis was carried out to determine the influence of the absorber solution recirculation on the system performance. The generator temperatures varied between 80 degrees C and 100 degrees C, while the cooling water temperatures varied from 20 degrees C to 34 degrees C. Cooling capacities up to 4.5 kW and evaporator temperatures as low as 4 degrees C were achieved with the system. The internal coefficients of performance varied between 0.3 and 0.62 depending on the system operating temperatures. The system also showed good stability and repeatability. (C) 2016 Elsevier Ltd.
