A growing number of Fridge Freezers, such as the Samsung RSH7ZNBP have anti-bacterial protection built into their design. This is a protective coating that is applied to the fridge part of the unit and kills bacteria. While effective, it shouldn't be used as a substitute for regular cleaning of your fridge freezer. It's recommended that you keep raw and cooked meat on different shelves and also constantly check and remove expired foods.
Fast freeze is a feature found on the Samsung RSH7ZNBP causes the product to run continuously, dropping the temperature quickly to it's coolest level. This freezes food much faster, preserving the flavor and texture. This function is best used before adding large amounts of fresh food, to ensure that it is all frozen quickly. Once the food is completely frozen the temperature will return to normal levels.
Older fridge freezers require regular thawing out, which is necessary when frost builds up inside the unit. Many modern fridge freezers, such as the RSH7ZNBP have a system built in which performs this task automatically. This is a good thing as it saves the owner extra work. Here's an excellent article on auto-defrosting fridge freezers if you'd like to learn more.
SmartFrost is something you'll find in Fridge Freezers such as the Samsung RSH7ZNBP that aims to combat the build up of ice. It's an environmentally friendly process that's up to 60% more efficient than existing fridge freezers. Another benefit is that SmartFrost is built into the walls of the fridge freezer so that it doesn't take up any space or require awkward cleaning.
