The difference is direct and indirect convection cooling.
Direct cool refrigerator meaning.
Direct cool refrigerators are more energy efficient.
Remember the old refrigerators with single compartment with a freezer box on the top having lots of cooling coils wrapped around the freezer.
Therefore unlike frost free units direct cool units.
Potential capacity of a direct cool refrigerator is 50 to 250 liters.
At one point in time we had the manual defrosting refrigerators at home.
Water vapor that contacts the cooled surface freezes.
Direct cool refrigerators use convection to spread cool air and need to be manually defrosted.
Direct cool is one of the two major types of techniques used in domestic refrigerators the other being the frost free type direct cool refrigerators produce the cooling effect by a natural convection process from cooled surfaces in the insulated compartment that is being cooled.
Those are direct cooling refrigerators.
Let us go on to look at the difference between these two technologies direct cool refrigerators vs frost free refrigerators.
Direct cool refrigerators typically come with a single door whereas frost free refrigerators have a double or triple door or even side by side doors.
The refrigerators have seen a vast improvement in technology.

Now we have frost free refrigerators.
Frost free models are better at maintaining consistent temperatures and keeping food items fresh for a longer period of time.
