Prerequisites
For exchange/transfer students:
General admission requirements.
Main purpose
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.
Knowledge
Following completion of the course, the student can:
- Identify and explain the indoor climate parameters and their impact on the ventilation and management and thereby the building´s energy demand.
- Account for the Building Regulations requirements for building energy demand, indoor climate and building services.
- Account for different principles of ventilation (natural, hybrid and mechanical ventilation).
- Calculate and choose different component in a ventilation system, including heating/cooling coils, filters and ventilation units.
- Identify different controlling strategies for a ventilation system.
Skills
Following completion of the course, the student can:
- Carry out a justified choice of ventilation principle and automation system based on the function demand.
- Design a ventilation system with the necessary components based on 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.
- Account for BIM and the application of 3D design of a ventilation system.
Competences
Following completion of the course, the student can:
- Detailed design of ventilation in buildings.
- 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.
- Knowledge of calculation methodology of natural ventilation in buildings.
