That doesn’t even make any sense. Is it cold air depositing frost onto the coil, or hot air melting the frost? It can’t be both.
You know that frost building up on coils is a huge problem that breaks air conditioners, right? Frost clogs the air stream, and creates a feedback loop where the coil gets way colder than it’s designed to because air can’t pass through.
I could have been more specific: the air conditioner can be useful in rainy or foggy warm conditions where the air conditioner can still cool the air further, and a car air conditioner goes colder than a home air conditioner does, around 38-45F (3-7C). It can also help if something in the car is adding moisture to the air, like if the occupants are sweating. However, when it’s just a cold day fogging the windows, the air conditioner does not help. It does not have a mechanism to dehumidify the air other than to cool it. Turn the temperature up to warm the interior surface of the windows.
If you turn off the ac for a short period of time, you run heat over the coils to remove all the accumulated frost, snd switch over again. This just used air instead of heating the coils with a reverse loop. It constantly cycles this loop to accumulate frost and remove it. It can be both, the coils are colder than the air, it accurate condensate, just like your glass. Why does your glass collect moisture if you claim this scenario is impossible….?
You say others are just using Google and ai, but clearly you’re the one using those tools and have no experience. Or did you just start school and it’s your second day?
Coil freeze over like you’re talking about is from an improperly sized unit, the defrost cycle can’t work properly.
But all acs collect moisture and have condensate lines, even home ones
Car defrost cycles are explicitly for the windows, not the coils. You still haven’t explained the magic mechanism by which an air conditioner dehumidifies air that’s colder than the coils, just pointed to the existence of condensate like that makes your point somehow. I already covered that the air conditioner can dehumidify air cycling through the car if humidity is building up from something inside it.
The coils are not designed to freeze. Ever. Having to manually defrost the coils by turning off the A/C (you have to do it manually because no system is designed to work this way, because that would be a stupid design) and run warm air through it means your system is malfunctioning.
Take the last word, if you want. Arguing on the internet is pointless.
Using quotes from your textbook, please explain why it’s called deFROST. If what you’re saying is true, it would be decondensation or something along those lines.

Spoken like someone talking out of their ass and making shit up, if what you’re saying was true, we wouldn’t be “arguing”. You would be providing facts, you could also provide sources to back up your asinine claims as well….
The moist air freezes to the coils of the ac unit, which is than heated by heated air and drips out of the vehicle through a condensate drain.
How do you not understand that basics of an air conditioner? It doesn’t just cool, it conditions the air.

Uhhh… why do you think they have defrost cycles?

Does the HVAC engineer seriously need the mechanism of condensation explained to them…?
Coils frost, glass can frost, you’re ignoring reality for your textbook numbers.
It can also freeze, because it’s -20c outside lmfao.
I’m inclined to believe him over you or the other guy 🤷. I’m not an HVAC engineer, just a rocket scientist turned data analyst.
