3 cards from this section. Quick, good the night before a test.
What is the primary function of an economizer?
Think about the role of managing refrigerant flow.
Define a flash chamber.
It's related to the way vapor and liquid refrigerants are processed.
What is the primary role of an economizer in refrigeration systems?
Think about what factors improve efficiency.
True or False: A flash chamber can redirect vapor for further compression.
Recall the function of flash chambers.
You are tasked with designing a new refrigeration system for a large warehouse. How would you incorporate economizers and flash chambers to optimize the system's efficiency? Discuss the design considerations you would need.
Think about the overall system layout and energy needs.
Calculate how much energy savings could potentially be achieved by adding economizers to a refrigeration system with a base COP of 2.8, expecting it to rise to a COP of 3.5. If the input energy required is 10kW, what performance improvement would you estimate?
Use the COP formula to see how the changes impact energy use.
