Superheat & Subcooling Quiz for Refrigeration Engineers
Superheat and subcooling measurements become far more useful when you understand what they are telling you about the refrigeration system. This RDA Academy quiz is designed to help working engineers practise that thinking rather than simply memorise definitions. Use it to test your understanding of superheat, subcooling and how these measurements relate to refrigeration fault diagnosis.
It is aimed particularly at engineers working across supermarket, retail and commercial refrigeration who want additional practice between jobs or alongside their existing training. Questions are there to make you stop, think and apply your knowledge rather than rush to an answer. It is a practical learning tool, not a formal qualification. Work through the quiz at your own pace and use the results to highlight areas you may want to revisit.

There is no exact science to a fault — these are good examples, but they may not always be as clear. Use as a guideline; genuine understanding and training are needed to read properly.
