Unit Code: DPL644

Unit Name: Refrigeration and Air-Conditioning Services

Description: Engineering technologists are likely to encounter changes related to the advancement of technology that is being spurred on by the need for increased energy efficiency. The HVAC industry is rapidly changing and also the expectations from stakeholders are high for specialized HVAC personnel. In this course, Thermodynamics and Heat Transfer principles for the analysis and design of refrigeration systems and comfort conditioning systems for buildings are introduced. Refrigeration cycles are studied. Operation and rating of system components are evaluated with specific emphasis on heat flow in condensers, evaporators, and cooling towers. Temperature and humidity control along with air handling equipment and ducting and refrigerants and environmental factors, are studied.

Learning Target Outcomes: On successful completion of this course, you should be able to: 1. Apply knowledge of engineering thermodynamics to wide practical procedures and practices. 2. Gathers engineering knowledge from sources such as standards and codes of practice and identifies the most relevant. 3. Demonstrate knowledge of the societal, health, safety, legal and cultural issues and the consequent responsibilities relevant to engineering technician practice and solutions to well-defined engineering problems. 4. Understand and evaluate the sustainability and impact of engineering technician work in the solution of well-defined engineering problems in societal and environmental contexts. 5. Function effectively as an individual, and as a member in diverse technical teams. 6. Presents clearly written reports for both technical and lay audiences, as is appropriate. 7. Presents work verbally in a clear and articulate manner, using visual aids appropriately. 8. Recognize the need for, and have the ability to engage in independent updating in the context of specialized technical knowledge.
