If the refrigerant is low the evap will hiss. And if the refrigerant is low, the eval pressures can be low and the boiling point drops and the that can generate frost. On a 24C day, you don't need much AC. On a hot day the anti frost might not do any cycling.
I found that a pressure of 33-34 PSI on the low side of the system works well and this prevents temps from getting to freezing. Can you get DIY recharge kits there. The ones with a pressure guage let you see whats going on.
Got ACC, could the feed to the antifrost be cycled by the ACC and you see that, but the anti frost switch might not be doing the cycling?
I don't know when the anti frost was improved. When it does not cycle, the compressor over temp switch will which causes it to fail. So its good if you can detect that it does cycle.
