Why frost and dew are generated?
When warm and humid air contacts something cold, dew is generated. For example, if you put some ice in the glass in your room,
air around the glass will be cold down and some dew may be generated on the outer surface of the glass.
In the same way, when warm and humid air enters into the refrigerator at the door opening, the warm and humid air contacts cold
inner wall and little dew may be generated.
Accordingly, if the door opening is too frequent or too long, dew will be accumulated at every door opening. In some cases,
dew may be frozen to generate some frost or ice flakes in the freezer compartment.
