Description
Establishes comprehensive heat and mass transfer, psychrometric, and refrigerant state relations needed to rigorously model a wide variety of cooling and dehumidification processes. Effectiveness-NTU methods using concentration and enthalpy difference analogous to temperature difference formulation are covered. Two-phase moving boundary models are formulated for evaporator and condenser models. Physical and semi-empirical compressor models are comprehensively explained working with measured and published performance data. Numerical methods of successive approximation, grid search and Newton-Raphson are applied to solve systems of non-linear equations and systems of empirical and first-principles component models. Linear regression methods to identify models from measured cooling load time series and resulting model used to estimate seasonal performance of a given chiller or heat pump design.
