Air conditioning is a mystery for so many in the industry. The physical principles are hard to understand at the fundamental level, even for engineers. So much of the technology is learned by experience. Even the best computer simulations are little better than educated guesses. Simple things like figuring out the correct refrigerant charge are still done by trial and error. The ultimate users, the people who experience air conditioning, can be equally difficult to understand because so much relies on subjective perceptions modulated by mood, preconceptions, habits and prior acclimatization. So there’s no expert, just humans trying to find a way through all the difficulties and challenges to keep themselves and others comfortable in a warming world.
