Information about fees and unit costs
Heating, Ventilation and Air Conditioning (HVAC) is closely related to human habitation, comfort and productivity. It also consumes considerable amount of energy. With increasing global warming, it is becoming one of the most important engineering systems in modern buildings.
This unit will introduce you basic principles of HVAC and refrigeration systems. It will discuss the design factors and practices related to the design and operation of HVAC systems. It will also provide you with other relevant knowledge commonly used in the building services industry. This course should therefore provide you a good basis to undertake further study, research and professional work in this field.

Note: Subject outlines often change before the semester begins. Below is a sample outline.
Rationale
Heating, Ventilation and Air Conditioning (HVAC) is closely related to human habitation, comfort and productivity. It is also one of the most important engineering systems in modern buildings. This unit will introduce the basic principles of HVAC and refrigeration. It will discuss design factors and practices to provide you with a detailed knowledge of issues commonly encountered in the building industry. This is a third/fourth year unit, so you are expected to apply knowledge and skills learnt in previous years and further develop skills in problem solving and critical analysis for later project work.
Aims
The aim of this unit is for you to achieve basic competence in heating, ventilating, air conditioning and refrigeration systems to achieve effective and efficient design solutions
Objectives
By the completion of this unit, you should be able to:
- apply basic theories of thermodynamics, heat transfer, and fluid mechanics to the design of HVAC systems.
- determine design conditions and select appropriate design criteria.
- calculate thermal loads and energy uses and size and select HVAC equipment.
- demonstrate importance of energy efficient design.
Content
- Human comfort and Indoor environmental quality;
- Thermal principles and Psychrometric analysis;
- Calculations of thermal Load and energy use;
- Refrigeration cycles and Refrigerants;
- Design and selection HVAC systems;
- HVAC Controls and Energy conservation technologies.
Approaches to Teaching and Learning
The unit outcomes will be achieved through a combination of theoretical study, weekly journal and practical design activities. In the weekly journal you will identify key points and concepts relevant to the topic and provide justification for your selection. Field visit and practical design activities are also an integral part of this course, and are designed to reinforce concepts introduced in lectures and to apply theory with hands-on practice and real world contexts.
Teaching Mode:
Hours per week: 3
Lecture: 2
Tutorial/prac: 1
Assessment
The assessment in this unit is designed to record your learning journey, to apply your knowledge in problem solving and analysis, and to perform practical design activities in real world contexts. It will be based on summarising and justifying key concepts in a weekly journal (20%), solving practical design tasks and problems (30%) in lab and real cases throughout the semester and a final examination (50%).You will receive verbal feedback on your progress in this unit during tutorials and discussions throughout the semester. The written feedback will also be provided for journal and practical design assignments. The written feedback you receive in mid-semester will provide valuable guidance on issues you may need to address for the second parts of assignments due at the end of semester.
Assessment name:
Journal
Description:
Each week, you will be required to identify FIVE key points for the topic learnt. You will also be required to provide appropriate justification for the selection of each key point.
Your journal will be evaluated on a continual basis with feedback provided as appropriate.

Risk assessment statement
You will undertake lectures and tutorials in the traditional classrooms and lecture theatres. As such, there are no extraordinary workplace health and safety issues associated with these components of the unit.
You will be required to undertake practical sessions in the laboratory under the supervision of the lecturer and technical staff of the School. In any laboratory practicals you will be advised of requirements of safe and responsible behaviour and will be required to wear appropriate protective items (e.g. closed shoes or steel capped shoes).
You will undergo a health and safety induction before the commencement of the practical sessions and will be issued with a safety induction card. If you do not have a safety induction card you will be denied access to laboratories.
Disclaimer - Offer of some units is subject to viability, and information in these Unit Outlines is subject to change prior to commencement of semester.
