Climatization and Refrigeration

Recommended Prerequisites

Applied Thermodynamics, Fluid Mechanics and Heat Transfer.

Teaching Methods

The lectures have a traditional format, which is essentially driven by the exposure of the subjects with the support of Powerpoint presentations and other multimedia means.

The practical classes are devoted to the analysis and solving of practical problems for application of the theoretical knowledge.

Learning Outcomes

The main scope of this course is to present and develop the fundamental concepts about heating, ventilating and air conditioning of buildings and related systems. The topics related with health and thermal comfort, building thermal behavior and loads, psychometric processes, ventilation principles and the HVAC components and systems, will give the students the necessary background to proceed in the design, analysis and operation of HVAC systems.

Work Placement(s)
