Abstract

In this work, we consider the absorption refrigerator driven by waste steam from fuel cells. The absorption refrigerator we consider does not use steam as a heat source from a boiler which can supply constant heat, but uses waste steam from fuel cells. Therefore the steam flow rate or pressure changes greatly as disturbance. In this work we aim to clarify the effect of the change in steam flow rate or pressure on the performance of the absorption refrigerator driven by waste steam. In this research, first a high precision dynamic simulation model is constructed to enable examination of the dynamic characteristics. In order to simplify the model, the delay in factors which can be ignored is considered as the lumped parameter system model. It was verified that the simulation model matched the results of experimental data to a high degree. With this simulation model, a detailed dynamic characteristics were clarified.
