Theoretical analysis and optimization of a double-effect series-flow-type absorption chiller

Theoretical analysis of LiBr/H2O absorption refrigeration systems

“…A number of researchers [1][2][3][4][5][6][7][8][9][10] have presented the energy analysis of single-effect, double-effect series flow and parallel flow absorption refrigeration systems using LiBr/H 2 O. In most of these studies, the authors have investigated the effect of several design and operational variables, viz.…”

Thermodynamic studies on HFC134a-DMA double effect and cascaded absorption refrigeration systems

“…The schematic diagram of the system is shown in Figure 1. Since the operation of this system is well known (Won and Lee, 1991;Xu and Dai, 1996), it is hence not described here.…”

On-site real-time evaluation of an air-conditioning direct-fired double-effect absorption chiller

“…The COP of single-effect absorption chillers working with LiBr-water can reach a real value of approximately 0.7, whereas double-effect chillers values vary from 0.9 to 1.25. Several researchers have worked on double-effect absorption machines, such as: Ziegler et al [3][4][5] who based his studies on the COP of the basic absorption cycle, Arun [6] in double-effect parallel-flow and series-flow chillers and Xu [7,8] in series-flow-type and parallel-flow-type chillers. However, there is a lack of experimental research on double-effect reverse parallelflow chillers, which are the purpose of this work.…”
