drier: component used in refrigeration systems to remove contaminants such as moisture and dirt
forced air system: system that provides ventilation and heat transfer through mechanical movement of air
radiation: heat transfer by wave motion (rapid vibration). Heat transfer from one body to another without the need for intervening matter
