Freezer
noun
A cool frozen storage is one which is really cold on the inside, so cold it can freeze things. This is called a freezer, not to be confused with 冷蔵庫, which is refrigerator, and doesn't have the kanji for "freeze" in it.
This is a jukugo word, which usually means on'yomi readings from the kanji. If you know the readings of your kanji you'll know how to read this as well.

げっ、冷凍庫、閉め忘れてた!
