HVAC Installations

Fundamentals of Thermodynamics, Fluid Mechanics, Heat Transfer, Air Conditioning and Refrigeration.

Topics at theoretical classes are presented through an application-driven approach, which tries to trigger discussion within the audience. “What-if” questions are extensively raised to engage students in the discussion. Students are also urged to deepen the study through self-conducted research. Each student presents a topic, followed by a discussion period. In theoretical-practical classes, problem solving is promoted to verify the knowledge level already acquired. Lab classes are grounded on software and technical catalogs of HVAC-R manufacturers. Additionally, one or more field visits to industrial and/or commercial units are provided for students to take contact with the technical facilities. Following these visits, students prepare summary reports, individually or in groups of two.
The evaluation of the course unit comprises:
1) Final written exam (62,5%);
2) Oral presentation of HVAC topic (17,5%);
3) Written report of field visit (10%);
4) Written report of lecture (10%).

The main aim of this course unit is to present the various types of HVAC systems, deepening the knowledge concerning the most common systems and looking to develop in the students the necessary skills in the areas of design, installation, commissioning, operation and maintenance of HVAC systems.
In the end of the course unit, students are expected to:
understand the relevant parameters contributing to comfort and indoor air quality;
describe different air conditioning processes, including calculation of the parameters involved;
describe different HVAC systems, identifying main characteristics, fields of application and key components;
know the principles underlying the selection and sizing of equipment used in the HVAC industry;
be aware of HVAC design guidelines, including installation, commissioning and maintenance requirements.
