The buildings we use in everyday life to live, work, study and socialise are becoming increasingly more complex in their design. As well as being subject to more stringent environmental emission targets, within these buildings the heating, ventilation and air conditioning (HVAC) systems play a vital role in maintaining the comfort of the occupants within the built environment.

This unit will introduce students to some of the most important HVAC systems and their supporting elements, and the underpinning science that is currently used in many different buildings around the world.

Subjects covered include: ventilation rates, systems, legislation, strategies and associated equipment. Also explored are topics such as air conditioning systems, cooling loads, psychrometric principles and processes, heating systems, fuels, combustion processes, boiler efficiency calculations and Building Management Systems (BMS).

On successful completion of this unit students will be able to explain the fundamental principles of HVAC systems and discuss the operational advantages of using BMS for maintaining the careful balance between ergonomic climate control and maximum economic efficiency.


Learning Outcomes

By the end of this unit students will be able to:

  1. Explain the operating principles of non-domestic ventilation systems.
  2. Explore the range of air conditioning systems.
  3. Investigate the operational characteristics of non-domestic heating systems.

Describe the role Building Management Systems (BMS) have in controlling and monitoring HVAC systems.
