- Slides provided by the teacher. - Educational objectives
- The aim is to provide students with knowledge and competence needed for HVAC systems design. Il shows the sizing criterions for the main components of a plant: air outlets, air distribution system, air treatment unit, heaters and coolers, water distribution system, heat generators, chillers. The course will provide students with preliminary competences for completing an exergy analysis and with knowledge about the main energy storage technologies.
- Prerequisites
- In order to be able to understand and apply the majority of the techniques described within the Course, students must have notions of mathematical analysis such as techniques of derivation and integration of functions of several variables, differential equations. Furthermore they must have successfully passed the Applied Thermodynamics and Heat Transfer exam and they have to be able to evaluate heat transfer in building walls and the performance of thermal engines. Finally they have to use psychrometric chart for energy calculations. Knowledge of these techniques represemnts a mandatory prerequisite for students planning to follow this course with profit.
- Teaching methods
- The course is organized as follows:- Lectures on all the subjects of the program;- Exercises in classroom as training for the oral test.
- Other information
- Not mandatory attendance, but recommended
- Learning verification modality
- The exam is constituted by an oral test.The oral tests consist of a discussion of about 30 minutes and is aimed to determine:i) the level of theoretical and methodological knowledge of the contents of the two modules;ii) the level of expertise in exposing possible technical solutions to problems of sizing of components and systems,iii) the independence of judgment in proposing the most appropriate approach for each scope.The oral examinations also aims to verify the student's ability to expose issues proposed by the Commission with property of language, to support a dialectical relationship during discussion and summarize the results of application of the theories studied.
