Curious if this would have any noticeable energy savings. Basically thinking of taking old semi-disposable plastic containers (the ones that like deli meat, butter, etc come in), freezing them outdoors, and letting them defrost (absorb heat) in the fridge/freezer. Basically back to the “ice box” model.
Anybody doing that and/or have any results to share? Mostly curious if it would be worth the effort.
Given that most of the temperature differential is due to heat transfer, it’s really almost completely irrelevant. A refrigerator doesn’t generate cold. It moves heat out and insulates. The only actual “gain” would be from the residual heat generated by the inefficiency of the electrical components. You’d probably negate any benefits just by opening the door to the house to get the ice.
