Ventilation Systems (from Spring 2020 - update in progress)

Code

CE-VEN1

Version

2.0

Offered by

Civil Engineering

ECTS

5

Prerequisites

For exchange/transfer students:
General admission requirements.

Main purpose

Knowledge

The student will be introduced to the knowledge about ventilation systems for air-exchange and air-conditioning in buildings and obtain the understanding of the preconditions, dimensions, functions and operations of these systems.

The student will work with criteria’s and methods used for design of mechanical ventilation systems and its components in a strategically way ensuring low energy consumption, high efficiency and human comfort. The course will operate with different principles of ventilation such as natural, hybrid and mechanical ventilation. After the course the student will be able to design, draw-up and calculate operational ventilation systems that can fulfil the requirements of a client.

Skills

After the course the student will be able to:
• Carry out a justified choice of ventilation principle and automation system based on the function demand
• Design a ventilation system with the necessary components on the basis of the required performance
• Optimize and adjust a ventilation system regarding the required airflow and energy efficiency
• Conduct a sound analyze of a ventilation system and reduce it according to the demand
• Make a simple fire analyze of a ventilation system

Competences

Topics

The student will obtain the following competences from the course:
• Detailed design of ventilation in buildings
• Principles of ventilation (natural, hybrid and mechanical ventilation)
• Distribution of air in rooms and design of diffusers
• Air treatment processes and Mollier diagram
• Calculation of ducts and design of the air distribution system
• Design of ventilation components (Fans, Heat exchangers, Pumps and Engines)
• Estimation of sound in ventilation systems and calculation of attenuators
• Calculation of energy consumption and heat recovery efficiency
• Understand the different ventilation automation and control systems
• Bips work specification tool for ventilation and building automation
• Knowing how to balance the airflow in a duct system by use of dampers (manual and automatic)
• Introduction to fire dampers and smoke management
