Thermal Engineering (Thermodynamics) Heat Transfer Engineering Fluidmechanics

This course is devoted to the design of HVAC systems to produce heat and cold in buildings and industry. At the end of the course, students will be able to: - Know the principles of heating and cooling equipment for buildings and industry. - Apply the knowledge to the sizing of thermal systems, using established methods. - Use software applicat6ions for building energy simulation and thermal systems. - Design HVAC (Heating, Ventilation and Air Conditioning) systems and buildings to minimize energy consumption. - Consult and comply with current regulations and standards in thermal systems and energy in buildings. - Develop research and HVAC projects, using reliable sources of information. - Size and select the equipment, according to criteria of efficiency, security, quality, cost, environmental awareness. - Communicate effectively projects and researches in HVAC systems, working both individually and in group. - Understand the relationship between buildings, energy consumption and environmental impact. - Collaborate with associated professionals within multidisciplinary teams.
