Learning Outcomes
Global and, in particular, European energy context identifies buildings as one of the sectors of high-energy economic activity (30 to 40% of total consumption), responsible for the emission of 36% of greenhouse gases, and
HVAC has a significant impact on meeting the buildings energy efficiency objectives in the short (2030), medium (2040) and long-term (2050).
To optimize it is necessary to estimate needs, know processes and technologies, this being the focus of the curricular unit of Climatization.
Thus, the main objectives of the course are characterized by:
(O1) Define the concept of air conditioning and thermal comfort.
(O2) Identifying the types of air conditioning systems, understand its operation and its implementation.
(O3) Mobilizing the knowledge previously acquired from psychometrics and heat transfer.
(O4) Define the concept of indoor air quality and know and understand the methods for determining minimum fresh air rates and exhaust.
(O5) Know and apply the heating and cooling loads calculation methods, required for the dimensioning of air conditioning equipment and systems.
(O6) Know the regulations in the energy performance of buildings.
(O7) Analyze and solve a case study that allows synthesize the knowledge acquired.
(O8) Develop the skills necessary for the practice of engineering in the HVAC design.
