Modelling HVAC and renewable energy plant and control

The chapter firstly presents an introduction to modern approaches to both steady-state and dynamic modelling of HVAC and related plant components and systems. Approaches to representations of components such as water-air heat exchangers are dealt with and their representation in systems that include control elements are described. Common approaches to solving the resulting equations are also presented. A series of simulation case studies are provided to illustrate the application of the methods. The chapter also presents examples of approaches to modelling the key components of a number of renewable energy systems that can be found integrated in buildings.
