Why a fridge does not work properly if the food is to o tightly packed inside?

When a fridge is too tightly packed, it restricts airflow, which is essential for maintaining an even temperature throughout the appliance. This limited circulation can lead to hot spots where food may not cool properly, potentially causing spoilage. Additionally, overloading can strain the fridge's compressor and cooling system, reducing efficiency and lifespan. Proper spacing allows for optimal cooling and energy efficiency.
