An inverse model for transient cooling and dehumidifying coil performance.

Author(s) : ZHOU X., BRAUN J. E.

Summary

This paper develops a simplified distributed inverse model for transient performance of cooling coils that is based on a forward model recently presented in the literature. The inverse model employs lumped parameters for conductances and capacitances. Simple empirical forms are employed for characterizing the impact of flow rates on airside and water-side conductances. Unknown parameters are determined using a two-step approach that requires a small amount of steady-state and transient training data. Dividing the parameter estimation process into two separate steps greatly reduces the training data requirements. A case study is presented for an 8-row cooling coil that was tested in a laboratory environment. The case study highlights the ability of the model to extrapolate performance when trained with a limited amount of data.
