 Performance prediction of an adsorption chiller combined with heat recovery and mass recovery by a three-dimensional modelFang He, Katsunori Nagano and Junya Togawa Energy, 2023, vol. 277, issue C Abstract: In this study, a three-dimensional model was formulated to predict and analyze the performance of an adsorption chiller (AC) with heat recovery (HR) and mass recovery (MR). A new value factor index (VF) was proposed to determine the parameters for optimal system performance. This model was confirmed to be suitable for performance prediction. The coefficient of performance (COP) can be improved from 0.503 to 0.604 at a cycle period of 14 min, which is consistent with the results of our previous study. Based on the VF, an optimal HR period of 24 min was determined. Subsequently, MR was introduced. In cases where an MR of 1 s was utilized, the specific cooling power (SCP) increased from 0.389 kW/kg to 0.393 kW/kg, while the COP increased to 0.607 with the HR. In addition, as the mass recovery period lengthened, the COP decreased. The accumulated recoverable sensible heat was discovered to be shared by the HR and MR. The HR reduces the accumulated regeneration heat. MR not only reduced the regeneration heat but also enhanced the sorption process.
