Abstract
Computer simulation is a very powerful tool in the study of heat transfer equipment and process dynamics. In the field of air-conditioning, a range of computer models of cooling coils has been developed. This article gives a brief review of the chilled water cooling coil models introduced in past decades. Following the development trend, it is suggested that while semiempirical models are still in use in heating, ventilation, and air-conditioning (HVAC) component simulation software, they will sooner or later be replaced by fundamental models in order to meet the need of performing more demanding and diversified analytical tasks. An example of a fundamental chilled water coil model is given. With a finite difference control volume conservation formulation, the model is able to give a flexible but accurate representation of the physical coil structure as well as the underlying heat and fluid flow processes. Accuracy of the model is demonstrated by comparing the simulation results with several coil models now popularly in use. It is also shown that this new model has distinct advantages and a promising future in plant simulation as the computer technology advances.
