Objectives

The Heating, Ventilation and Air Conditioning (HVAC) course is a complementary study of the Building Physics lecture, a first semester course related. The first main goal of the HVAC lecture is to improve the knowledge of the thermal behavior energy analyses of the buildings, the HVAC system and to give a first approach to the design an optimization of the different HVAC system available on the market. The efficiency of the energy consumption and the efficiency of the different HVAC system devices are used as a base of the design concerns.
The study of the heating and cooling building loads techniques and energy consumption forecast methods it is also included.
Finally, the lecture includes analysis and implementation of the national regulation related to the HVAC and Buildings

Program

1. Building Heating Loads analysis
2. Energy Estimation methods 1 – Degree Days Method
3. Passive Solar techniques for heating – Solar passive systems
4. National regulation - The Thermal Characteristics Behavior of the Buildings (RCCTE)
5. Cooling Loads analyses
6. Energy Estimation methods 2 – BIN Method
7. Analysis of the different HVAC systems
8. Heating Systems applied to the HVAC
9. Energy recovery systems
10. Heat and cooling sources – power plant
11. Economical analyses of the energy alternatives (renewable) applied to the buildings
12. Pipe line design considerations
13. Design of cooling storage devices
14. Principals of energy conservation in buildings and HVAC systems
15. National Regulation - Regulation of the Energy Systems of HVAC in Buildings (RSECE)

Teaching methods and learning activities

Theoretical issues will be presented at the begin of each lesson (more or less 60 min). Also those lessons can include analysis of real case studied of the HVAC systems and in this case the lesson can reach at 90 min.
The practical lessons include the resolution of problems and analyses of the particular cases studied that can be made individual or in small groups.
