I think during formation of frost only a part of latent heat is absorbed by the evaporator coils during frosting which will finally effect the overall heat transfer results in increasing the compressor effort.

Because due to frosting the heat transfer may be decreased in evaporator. So it takes more time to reach the cooling. It may increase the running cost of compressor.

Due to the formation of frost, we need more RE for cooling the same refrigerator because of the fact that frost will act as an insulator.

Once the frost is formed, it doesn't need to get form again, frost is stucked on coils, soair directly comes out cooling pad.

Frost becomes an obstruction for heat flow. That results in increase in power consumption for getting same amount of cooling.

Frost is heat barrier for heat transmission in evaporator coil due to which power is required more for same work.

You may also resemble frost as icing, which reduces efficiency of a refrigerating unit.

Due to presence of frost it acts as a insulator which create as barrier for heat flow.

Due to frost the system runs continuously. So increase the power consumption.

Ice.
The formation of ambient water vapours (gas) into ice is called frost.
