2 cards from this section. Quick, good the night before a test.
What is a vapor compression refrigeration cycle?
Think about the overall goal of a refrigeration system.
Name the four processes in the ideal VCR cycle.
They start with 'I' and 'I', then 'E' and 'E'.
What is the process of turning vapor into liquid in the VCR cycle?
Think about what happens after the compression phase.
True or False: The ideal VCR cycle considers all real-world inefficiencies.
Consider the term 'ideal' and its implications.
If a VCR system absorbs 300 kJ of heat from its environment and performs 100 kJ of work, what is its Coefficient of Performance?
Remember the formula for COP.
Design a simple model of a real-world refrigeration unit that accounts for inefficiencies found in standard VCR systems. Discuss the components that would need alteration to improve COP.
Reflect upon each phase of the ideal cycle and consider potential real-world adaptations.
