Ventilation systems in Volvo Cars Body Components

Sammanfattning: In this Master thesis work two types of ventilation system, mixed system and displacement system at the factory premises of Volvo Cars Body Components (VCBC) are investigated. A computer simulation technique was implemented to study the behavior of air movement and temperature distribution inside the factory for the two systems. The commercial CFD program Flovent is used for simulation purpose. Model verification was carried out with the measurements made. Results showed quite good agreement between these two values. The current model has then been used to predict the temperature distributions and air flow movement for different climate scenarios. Energy calculations were also made in order to find out the energy used by two systems annually. The results from the simulations showed that the displacement system gave better performance in every case in thermal comfort aspect, whereas in the energy aspect it was found that the displacement system used more energy annually compared to mixed system.
