HVAC and Refrigeration mind maps

HVAC and Refrigeration mind maps

The maps on this page connect topics across heating, cooling and refrigeration. One covers heat pumps in vehicles, including compressors, refrigerants and applications. Others look at air conditioning system classifications, chillers and the stages of a vapor compression refrigeration cycle.

Where to start

Start with Classification of Air Conditioning Systems if you want to compare all-air, all-water, air-water and unitary refrigerant-based systems. For a refrigeration topic, the map on vapor compression shows the stages of a closed cycle.

Follow one branch at a time and explain the connections in your own words. If a term or component needs more attention, use a flashcard deck on the unit page. Switch to a unit quiz when you want to practice answering questions, then return to a map to revisit the connections.

Choose a topic and follow a branch through the map.
