The perception of the inside of a freezer feeling warm while the outside feels cold can be attributed to a few factors:
Insulation: Freezers are designed to be well-insulated to prevent the transfer of heat from the external environment into the freezer compartment. The insulation helps maintain the low temperature required for freezing and storing food. As a result, the insulation keeps the cold air inside, making the interior of the freezer feel cold.
Heat exchange: Freezers employ a heat exchange process to remove heat from the interior and release it outside. The heat exchange occurs through the compressor and condenser located on the back or bottom of the freezer. These components work to remove heat from the freezer's interior and transfer it to the surrounding environment. Therefore, the heat released during this process can cause the outside of the freezer to feel warm.
Heat dissipation: The warm air released from the heat exchange process mentioned above dissipates into the surrounding room. If the freezer is located in an enclosed space or a small room with limited ventilation, the warm air might accumulate near the unit, making the area around the freezer feel warmer.
It's worth noting that the temperature difference between the inside and outside of the freezer can vary based on factors such as the freezer's insulation quality, the efficiency of its cooling system, the ambient temperature, and the duration and frequency of the door being opened.
