Course description

The aim of the course is to give engineering students a technical-design knowledge related to the field of HVAC systems. Based on the analysis of the interior microclimate and of the thermal and hygrometric loads, the various types of HVAC and the selection criteria are described from an energy and economic point of view for a system optimization. The problems encountered in the design stage and the design methodology of HVAC systems are shown. The students are required to carry out an exercise, aimed at verifying the capacity to design the different types of conditioning systems.

Knowledge and understanding:
The student must demonstrate:
- to know the fundamental principles of psychrometry and the thermo-hygrometric characteristics of building envelopes;
- to know the main components of HVAC systems, to understand their functions and the design techniques;
- to know the HVAC systems and to understand the design techniques.

Ability to apply knowledge and understanding:
The student must demonstrate that is able:
- to apply the fundamental principles of psychrometry to the design of building envelopes and HVAC systems;
- to understand the main issues related to plant components in order to identify the design solutions most suitable to specific applications;
- to analyze the main characteristics of HVAC systems and to carry out a preliminary design activity.

Autonomy of judgment:
The student must demonstrate that has developed the ability to evaluate critically and autonomously the issues related to the design of a building envelope and of a HVAC system and its components.

Communicative skills:
The student should have the ability to explain, in a simple way also to people who are not experts, the operation of HVAC systems and the features that must have a building envelope in order to optimize the thermo-hygrometric performance.

Learning ability:
The student must be able to update his knowledge continuously, through the consultation of texts and publications related to HVAC systems, in order to integrate the acquired knowledge.

Prerequisites

The students must have acquired the following knowledge provided by the courses of "Applied thermodynamics" and "Machines":
- fundamental concepts of thermodynamics;
- fundamentals concepts of the balances;
- basic concepts relating to machinery and components of plants.

Teaching Methods

The training contents are transferred mainly carrying out lectures and exercises. The teaching approach includes the stimulation of the student's curiosity regarding the knowledge of practical problems, and the development of the ability to solve them.

Learning assessment

The objective of the exam is to check the level of achievement of the course objectives previously indicated. The exam is divided into 2 parts:
- an oral test in which the ability to link and compare different aspects of the course will be evaluated;
- Discussion of the project developed by the student autonomously in order to evaluate the mastery of the topics dealt during the course.
