Parametric Study of a Single-Stage Two-Bed Adsorption Chiller
Publication: Journal of Energy Engineering
Volume 143, Issue 4
Abstract
This study examines the influence of operating conditions and heat exchangers’ characteristics on the overall performance of a single-stage, dual-bed adsorption chiller. A simple lumped parameter model is utilized in order to simulate the thermal behavior of the chiller. The overall performance of the chiller is evaluated using four performance indicators, namely, (1) cooling capacity, (2) coefficient of performance, (3) chiller efficiency, and (4) waste heat recovery efficiency. A parametric study is performed in order to determine the way the overall performance of the chiller is affected by operating conditions and by overall thermal conductance of the chiller’s heat exchangers. Then a sensitivity analysis is carried out to investigate which parameter affects each performance indicator the most. It is observed that the heat sink temperature is the parameter with the biggest impact on the adsorption chiller’s performance. Other influential variables are the heat source and the chilled water inlet temperatures.
