I want to buy a deep-freezer and have some questions...?

Question

I know I'm going to for a chest freezer, but I noticed many are not frost-free. Since I'm keeping this thing out in a very-humid Texas garage, should i go for a frost-free or a manual.

Why don't they make these things frost-free? This is the 21st century after all.

Answer 1

A deep freeze is NOT the same as your freezer compartment in your refrigerator. It is designed to maintain a MUCH lower temperature, around 0 degrees F. The freezer compartment is designed to work best at around 25 degrees F. Frost-free means that periodically, the freezer coils are hit with warm refrigerant, which melts off any frost which forms, which means the temperature is RAISED to above freezing in a portion of the freezer compartment for a period of time. It is much easier to raise the temperature in the coils from 25 to the point it melts off the frost than it is starting at 0. Less heat is added to the compartment than would have to be used for a deep freeze, which means energy consumption goes up for the frost free deep freeze because it has to work harder to accomplish the same task, which defeats the purpose. The reason why frost even happens is that moist air gets in when you open the door. Since your refrigerator is frequently opened, lots of humid air enters, and unless the freezer compartment  is a chest type, cold air simply flows out and warm air flows in. With a door that swings open to the left or right, it simply lets the cold air flow out and warm air enter. A deep freeze is designed to opened once in a while, and as a chest, the cold air naturally stays in the chest. Cold air sinks in warmer air, so the cold air stays in the deep freeze even when the top is open. Ever notice many stores have chest type freezers where they have frozen foods? Ever wondered why they are not covered AND the foods STAY frozen? So, because the deep freeze is not opened frequently, and warm moist air does not enter much even when it is open, it does NOT have to be frost-free like your refrigerator freezer compartment which lets the cold air out and warm air in EVERY time you open it. Stick with a chest type of deep freeze and skip the extra cost for a frost free model which will just consume more electricity than a standard model which you MAY have to defrost once a year.
