DESC9067: Mechanical Services

This unit reviews the need for and application of Mechanical services in the built environment - in particular commercial buildings. Mechanical services are responsible for significant portion of energy and water consumption in buildings. Thus they have become important components of most modern building complexes, with a strong influence on other services and the architecture. This unit provides an introduction to these services by experienced presenters, including from the industry, for recent graduates or diplomats in mechanical engineering and an understanding of fundamental principles and practice for people from backgrounds other than mechanical engineering. Students will acquire skills in appreciation of impact of mechanical services on the environment, including recent mandatory regulations, together with estimating ventilation, cooling and heating requirements, design of simple ventilation, air conditioning and smoke hazard management systems, combined with an overview of water, refrigerant, ducted systems, with applicable equipment, energy, noise, human comfort, air quality criteria. Principles of heat transfer and fluid flow are applied to applications of mechanical ventilation, air conditioning and smoke hazard magagement, to satisfy regulations and standards, occupant and community expectations. The practical basis of the programme leads to a design assignment involving selecting equipment and systems to provide mechanical services in a building.
