Course Objectives: (numbers in the parenthesis indicate relationship to ME program outcomes)

At the completion of the course, students will have demonstrated the ability to

· Apply principles of fluid dynamics, thermodynamics and heat transfer to the study of refrigeration cycles, turbo-machinery and other thermal components such as heat exchangers, HVAC coils, pipe and duct networks [2]

· Analyze and explain the operation of different refrigeration cycles, psychrometric processes, pumps and fans [2]

· Design HVAC coils, shell and tube heat exchangers to meet the engineering and economic constraints [4,7,11]

· Analyze and select pumps and fans and design the piping network, duct systems. [2,4,11]

· Relate fundamental laws to useful engineering models and, in turn, link these models to design decisions, when confronted with design and open-ended problems. In providing these solutions, demonstrate the knowledge of contemporary issues such as global warming, ozone depletion, and ethical responsibilities and impact of global and societal context through adherence to the relevant codes and standards and broad education. Students address these issues through design of shell and tube heat exchangers, design projects involving innovative systems such as energy recovery devices, dedicated outside air systems (DOAS), fuel cells, combined heating and power (CHP). Design projects having these systems save energy, and reduce global warming and ozone depletion, confirmed by the quantitative estimates. [2,4,7,11]
