About HVAC and Refrigeration
GoConqr OriginalWhat the resources cover
This unit sits in the Energy Conversion Systems strand of Mechanical engineering. It splits roughly into heating, cooling and air handling. On the heating side, the quiz Chapter 3 - Hydronic Heat Sources looks at gas- and oil-fired boilers and the cast-iron sectional boiler. Chapter 1 - Modern Hydronic Heating asks how water-based systems move thermal energy from where it is produced to where it is needed.
On the cooling side, you will find quizzes on refrigeration auxiliaries, compressors and pre-start-up procedures, plus a flashcard deck on valves and metering devices. Air handling is covered by questions on central station air handling units, fan coil units and terminal reheat systems.
Where to start
- Begin with Chapter 1 - Modern Hydronic Heating if you want the heating basics, or the mind map REFRIGERATION if cooling is your focus.
- Move to Chapter 3 - Hydronic Heat Sources for boiler types.
- Try 4.11 Refrigeration Auxillaries and Operation, which asks about low suction pressure, frost on the drum bottom and low-pressure controls in ammonia systems.
- Finish with the mixed quizzes, such as MECHANICAL - HVAC and RMO Exam, which test whether you can recognise a system or decide a first operating step.
Using quizzes and maps together
Read a mind map first to see how the parts connect. There are maps on chillers, VRF systems, split system air conditioners, vapour compression cycles and refrigerants such as CO2. Then take a related quiz and note every question you miss. Go back to the map for those branches only.
The flashcard decks help with vocabulary. Refrigeration & AC covers practical repair questions, such as what a swaging tool set is used for, while HVAC Terms and Abbreviations is useful for the shorthand that turns up in controls and air handling questions.
Who can use it
Most of the material suits university students and professional candidates, with teachers able to pick out quizzes or maps for a class. Everything was made by GoConqr users, so check the wording against your own course notes.

Frequently asked questions
Which resource should I open first?
For heating, start with the quiz Chapter 1 - Modern Hydronic Heating, which covers how water-based systems carry heat. For cooling, the REFRIGERATION mind map gives an overview before you try a refrigeration quiz such as 4.10 Refrigeration Principles and Systems.
What do the mind maps on this page cover?
There are over 20 maps. They cover chillers, VRF systems, split system air conditioners, the classification of air conditioning systems, vapour compression steps, and refrigerants including HFC and CO2. Others look at filter dust collectors, induction heating and a microwave oven.
Are the resources free to use?
Yes. Every resource listed here is free to open, study and take, with no account needed. A free account also saves your quiz scores and lets you make your own quizzes, mind maps, flashcards and notes.
Who made these resources?
They were made by GoConqr users, not by GoConqr itself. Over 30 contributors have added material here, so styles and depth differ. It is worth comparing a quiz with your own course notes if you spot something that looks different.
Which levels do these resources suit?
Most are aimed at professional candidates and university students, and a smaller share is at school level. The page does not tie its resources to a named exam, so choose by topic, such as boilers, controls or refrigeration auxiliaries.
What if I cannot find the topic I need?
Try a nearby resource first. Quizzes such as MECHANICAL - HVAC and the HVAC mind map cover several systems at once. If a gap remains, you can build your own flashcards or mind map on the topic.
