Refrigerant will flow hardly in cooling coils so increase power consumption.

Kaustubh said:   7 years ago
Frost becomes an obstruction for heat flow. That results in increase in power consumption for getting same amount of cooling.

Mohd Raza said:   8 years ago
Frost is heat barrier for heat transmission in evaporator coil due to which power is required more for same work.

Pradeep gk said:   8 years ago
Frost is a formation of ice particles on evaporator coil.

Prince said:   9 years ago
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.

Ice.

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

What's meaning of frost?

Please explain brief?

Haris said:   1 decade ago
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.
