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

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

                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.

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

                What is the meaning of frost?

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

                What's meaning of frost?
Please explain brief?

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

                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.
