CFD Simulation of HVAC System in a Building using ANSYS - Fluent
Keywords:CFD analysis; indoor climate; HVAC system; 2Dbuilding: numerical simulation; ANSYS Fluent
The aim of the study is to simulate the functionality of a HVAC system in different situations, summer and winter time, using specialized software ANSYS-Fluent. A 2D building model was realized and simulating the internal conditions represented the main elements of the study. There are studied the indoor air temperature and air velocity in different conditions. The results are presented as graphs/plots and spectra of interest parameters. HVAC system functionality simulation using ANSYS-Fluent is providing important results for the studied scenario.
The study aimed to simulate HVAC system functionality in different situations, summer and winter time, using specialized software ANSYS-Fluent. The realization of 2D building model and simulation of external and internal conditions it represents the main elements of simulation. As general conclusion, it can be stated with certainty that the recently implemented HVAC system reaches its task and provides adequate comfort conditions inside the amphitheater during both seasons.
The average velocities, are slightly bigger during summer season, due to higher airflows required. However, this effect doesn’t affect the occupants, because they are lower than the comfort ones. HVAC system functionality simulation using ANSYS-Fluent is providing important results for the studied scenario. This type of analysis can be used for pre-examination of the future projects in order to obtain functional systems and verify the all requirements for the HVAC installation. The results can be used in further analysis for determining the correlations to the main comfort indicators, PMV and PPD.
