Coupled TRNSYS-CFD simulations evaluating the performance of PCM plate heat exchangers in an airport terminal building displacement conditioning system

Performance of coupled building energy and CFD simulations

The integration of building energy simulation (ES) and computational fluid dynamics (CFD) programs can provide more accurate prediction of building energy use and indoor environment due to the complementary information provided by the two programs. This paper outlines briefly a coupled energy simulation and computational fluid dynamics program with different coupling methods and validates the c...

Dynamic Simulation of a Complete Solar Assisted Conditioning System in an Office Building Using Trnsys

To minimize environmental impact and CO2 production associated with air-conditioning system operation, it is reasonable to evaluate the prospects of a clean energy source. Solar energy can drive an absorption chiller in order to satisfy the cooling needs of buildings. The objective of this work is to build a simulation environment that can evaluate accurately the energy consumption of an air co...

Analysis of Fouling in HVAC Heat Exchangers by CFD

The purpose of this study is to identify parameters influence on the particle deposition within fin and tube heat exchanger of air-conditioning systems by CFD analysis. First the basic sketch of periodic geometry drawn and meshing operation including boundary conditions was performed. Then the gas side properties and flow parameters were solved by ANSYS Fluent 14.5 software. Lagrangian equa...

Coupled Computational Fluid Dynamics (CFD) and Artificial Neural Networks (ANNs) for Prediction of Thermal-hydraulic Performance of Plate-fin-tube Heat Exchangers

Plate fin-tube heat exchangers are used extensively in heating, ventilating, and air conditioning, process engineering, and refrigeration systems. They have a high degree of surface compactness. Substantial heat transfer enhancement is obtained as a result of the periodic starting and development of boundary layers over interrupted channels formed by the fins and their dissipation in the fin wa...
