What is a frost-free freezer, and how does it work?
A frost-free freezer is a type of freezer that uses a defrosting mechanism to prevent the buildup of frost and ice on its walls and shelves. This mechanism, also known as an automatic defrost system, works by periodically heating the freezer’s evaporator coils to melt any frost or ice that has accumulated. The melted frost is then drained out of the freezer, usually through a drain or a collection pan.
The automatic defrost system is typically controlled by a timer or a sensor that monitors the freezer’s temperature and humidity levels. When the system detects that the freezer needs to be defrosted, it will activate the heating element and begin the defrosting process. This process usually takes several hours to complete, during which time the freezer’s temperature may rise slightly. However, this is a normal part of the defrosting process, and the freezer will return to its normal operating temperature once the defrosting cycle is complete.
