Adaptive HVAC zone modeling for sustainable buildings
Control of energy flows within a building is critical to achieving optimal performance of heating, ventilation and air-conditioning (HVAC) systems. To design optimal HVAC control strategies, a dynamic model of the HVAC system – particularly the building zones that it services – is essential. As analysis of building energy consumption is facilitated by the accurate prediction of indoor environme...
متن کاملHVAC System Validation Simulation
This paper describes the concept of using simulation as a tool for performance validation and energy analysis of HVAC systems. Recent advances in control system technology, including the development of open protocols such as BACnet have made sensor and control signal information from various components and subsystems in a building more accessible. This development has created significant potent...
متن کاملMulti-scale Spatial Modeling for Logistics System Reliability Evaluations
This article proposes a multi-scale model suitable for describing patterns of store locations in a large-size supply-chain system. This model uses continuum approximation to simplify the detailed logistics network and supports various levels of decisions, such as robust logistics network designs and service area allocations for distribution centers. Several definitions and formulas are develope...
متن کاملModelica Based Dynamic Modeling of Water-Cooled Centrifugal Chillers
In this paper, the transient model of a water-cooled centrifugal chiller is developed in Modelica with Dymola and the TLK/IfT Library (TIL). The centrifugal compressor is modeled in detail based on the turbomachinery theory. The chiller capacity control is achieved by the combination of variable inlet guide vane (VIGV) and variable speed drive (VSD). The shell-and-tube heat exchangers are discr...
