There has been increasing interest in finding alternative refrigerants for refrigeration and air conditioning systems, as many traditional refrigerants have been found to contribute to ozone depletion and climate change. The purpose of this assignment, as an individual learning project, is for you to cover refrigeration subjects not addressed in your study guide's theoretical chapters. You must include the following information in your research: Classification of Vapor cycle Refrigeration. (10) Methods of Refrigeration. (5) Application of air cycle refrigeration system. (15) Refrigeration's modern applications. (10) Refrigeration technology as storing energy from renewable sources, such as solar and wind power. (5) Highlight the influence of hydrochlorofluorocarbons (HCFCs) on global warming and the impact on the ozone layer. (15) Alternative refrigerants for refrigeration. (10) Reflect on the usefulness of a specific assignment and comment on what you've learnt and the understanding you've gained. Explain why independent learning is important, and how you plan to approach informal learning in the future (personal strategies, preferences and learning style). (5) As you've learned more about alternative refrigerants for refrigeration and their safety precaution, share your thoughts on the topic. (5)
