Abstract

<p>It is necessary to know the parameters of the heat exchangers such as condenser, evaporator and adsorbent beds implemented in an adsorption chiller in order to evaluate its performance by numerical simulations. The parameters are UA-value and thermal capacity. However, these values are not available generally for actual appliances. The objective of this study is to estimate the parameters based on the numerical simulations. The outlet temperature of the plant is compared with the simulated one, which defference is fed back to adjust the estimated parameter with iterations. The study investigated the performance of the estimation procedure and found that the estimated parameters converged to the true values. The results show that the 4 parameters of condenser and evaporator can be estimated simultaneously.</p>
