From the author: Dynamic coil models are utile in the development and evaluation of feedback controllers and fault detection and diagnostics algorithms. Existing models in the creative writing of recognized artisti value have not been validated completely using experimental selective information and have not been evaluated in terms of trade-offs among model accuracy and computational requirements. This paper develops a computationally fast, propagated model for the transient conduct of cooling and dehumidifying coils. The model utilizes assorted steady-state performance indices that simplify dynamic modeling, including fin efficiency, air-side effectiveness, and water-side effectiveness. Predictions from the simplified model were equated with a elaborated reference model and with other simplified models from the literature. Comparisons with elaborated experimental measurements are given in a associate paper (Zhou and Braun 2007). The model provides very precise prophecies of coil transient performance and executes more than 1000 times more immediate than real-time on a 1.2 GHz personal computer. As a result, it is very practical for implementation within system simulation programs that carry through over long time periods, such as a year.
