They already explained that, because it's intended to defrost frosted windows, not because it defrosts frosted condenser coils. How would you even know when to use it if that was the case?

Spoken like someone talking out of their ass and making shit up, if what you're saying was true, we wouldn't be "arguing"

Spoken like someone arguing for the sake of arguing, aka, a troll. Have fun under your bridge!

The deFROST button that looks like this?

It is quite obviously defrosting the windshield. Its other use is removing condensation from the windshield.

So I don't know anything about the math or physics of the situation, but I do actually work on cars. A car has both and evaporator and heater core. Meaning it is capable of using the evaporator core to act as a dehumidifier before the fan from the blower motor pushes it through the heater core and up into the cabin. The heater core gets it's heat from the engine coolant. When the heat is activated a little internal door opens and runs the coolant through it. I'm assuming you'd understand the rest. But thats why it takes time for your hot air to blow. The engine hasn't heated up enough to transfer it to the coolant.
