If you fill up any unused space inside your freezer will it use less electricity? The theory is that the compressor will spend less time and, therefore, energy keeping the interior cold.
There are two problems with this idea. The first is that air needs to circulate inside the freezer to effectively cool. The freezer cools the air, the air cools the food. Blocking all the air flow hurts your freezer's effectiveness and also stops it from reading the correct freezer temperature so it knows when to turn on and off the compressor. (Imagine putting your house thermostat in a closet with the door closed and no circulation.) The second issue is that the compressor is already turning off when not needed. Empty space doesn't take any additional energy to cool so filling it up doesn't save you anything. You might argue that if you open the freezer and it has a lot of empty space, warm air will rush in and that air will have to be cooled, but since the freezer is closed almost all the time I can't see a lot of savings there. I think you will lose more by keeping the door open to pack and unpack every time you need to move something around.
When I worked at the apartments, residents were continually filling the freezers too full and blocking air flow. The freezer coils would then freeze over and I would have to defrost them. One resident filled his freezer compartment with raw chicken three times, causing me to have to remove it and thaw the refrigerator coils. I finally told him to buy a small freezer for the chicken.
I don't Think your Idea Will Work. Course If Block the freezer Then Composure Will take more time to circulate the air.
