EXPERIMENTAL INVESTIGATION AND PARAMETRIC ANALYSIS USING CFD SIMULATION FOR COOLING OF CABIN THROUGH AUGMENTED VENTILATION SYSTEM WITH PASSIVE HOT AND COLD SOURCES

摘要

Passive cooling of buildings through natural ventilation has received the attention of researchers in recent years. In the present work the concept of producing cooling effect through augmented ventilation by excess hot energy available during summer days from the solar flat plate collector and by storing cool energy available during the early morning hour in the Phase Change Material (PCM) based storage system is attempted. An experimental setup is made to study the cooling potential achieved due to the novel concept of augmented ventilation system and the results are reported. A CFD analysis is carried out using ANSYS-CFX software and the results are validated using the experimental results. The CFD model is further modified for the real size configuration and using the same boundary conditions the performance of the system is analysed for various parameters of interest.
