Design And Simulation Of HVAC System In Culture Center

With large increase in economic development and building construction, designs about HVAC system gradually attract more attention in the field of architecture in order to greatly improve the indoor air quality and the sense of comfort. Meanwhile the more frequented phenomenal of severe air pollution and the greenhouse effect are occurred, the concept of modern life is steadily developing into the direction of energy saving and environmental protection. This dissertation considers the cultural center as a researching platform which one of the walls is glass installation. For this special design, advantages are obvious like absorbing solar radiation, providing adequate lighting and increasing the aesthetic sense of building structure. As a foothold of thermal energy and power engineering discipline, this thesis is conducted in the HVAC system design, computational fluid dynamic simulation and improvements of the ventilation system based on the aspects of energy consuming in the background of practical engineering project.By the discussion of the importance significance about the design of HVAC systems which highly ameliorates the quality of the housing environment, the HVAC system specification design is proposed in the way of the analysis of different type compartments, the equipment’s performances and the project feasibility. To achieve the requirements of indoor comfort standards and low indicators of energy consumption, HVAC system is due to leading equipment management and listed enhanced improvements as a reference of dynamic temperature distribution. Referring the demands of instantaneities and accuracies in k-ε standard turbulence model, it is introduced that an analog simulation of ventilation system is applied in the hall of Culture Center. According to data provided by the meteorological bureau in Algiers, the relationship between the fan power, solar radiation and the interior/exterior temperature is obtained by the thermal characteristics of the installation and computational fluid dynamic model which illustrates the input/output power efficiency and low noise figure. Through the CFD model and the energy consuming analysis of the hall, the modified model which adds two more double-door-size inlets in the wall decreases the electricity consuming and carbon dioxide emission; moreover, it economizes the operating cost.
