Unit 1, HVAC: Upon successful completion, the student should be able to evaluate the suitability of a given heating, ventilating and air conditioning (HVAC) system for specific applications, be able to analyse and design refrigeration and air conditioning systems and understand the design optimisation process for a range of systems.

The content includes topics from applications of refrigeration and air conditioning, psychrometry and conditioning process, indoor air quality, heating and cooling loads, air conditioning and distribution systems, pumps and piping systems, cooling and dehumidifying coils, HVAC system control, acoustic and noise control, design for efficiency, vapour compression refrigeration system, refrigerant, multi-pressure systems, cooling towers, vapour absorption refrigeration systems, absorption systems, heat pumps and energy conservation.

Unit 2, Alternative Fuels: Upon completion, students should comprehend the special requirements for the preparation and burning of alternative fuels compared with their conventional counterparts; and appreciate the difficulties of storing, handling and the safety requirements of alternative fuels and have skill in performance testing of alternative fuels and in specifying designs for several applications.

Topics covered include combustion, emission, storage and other properties of alternative liquid and gaseous fuels as replacements for conventional fossil fuels; the special requirements of alternative fuels in burners, furnaces and in transport; engine-fuel matching, engine mapping as a tool for optimising energy and emissions for vehicle applications; and storage options, fuel degradation, environmental impacts.

Two 2-hour examinations (50%); practical and project work not exceeding 20 pages including computations, diagrams, tables and computer output (50%). Weighting of the non-examination assessment components will be made known at the commencement of the subject. Students must pass both examinations and project work.
