Domestic freezers

Freezers are used to maintain the contents in a frozen state. Maximum freezers work at nearly zero degrees Fahrenheit or minus eighteen degrees Celsius. Domestic freezers may be standalone units or as a part of the refrigerator. Usually, Domestic freezers are straight units, similar to refrigerators or chests, similar to upright units placed on the back. Modern freezers also have an icemaker.

Types of freezers

Domestic freezers are available in a wide range of sizes. The small size is called as the 4I Peltier fridge and can maintain six cans of beer. The large size may have the same height as a human being and the width may be one meter. The capacity is 600I. For small households there are small models that are eighty six centimeters in height. They can be placed below kitchen work surfaces. Freezers and fridges can be combined and stacked one above the other or placed on side of other. Those fridges that do not have a true freezer can contain a small compartment for preparing ice. Freezers can have drawers to place food. Those which do not have any divisions are called Chest Freezers. Freezers are free-standing or may be built in a kitchen. Compressor refrigerators are the most widely used and they make some noise while operation. Wherever noise is not desirable, Absorption or Peltier units are bought. Peltier coolers do not have a bulky mechanism and hence are used in small refrigerators. Compressor and Peltier refrigerators run compulsorily on electric power. Absorption units can be run on some heat source. Dual gas - electricity and sole gas units are the two types available.

Selection of freezers

Domestic or low cost industrial freezers can be classified into two types. Some have refrigerant coils in the chamber and are very cheap. The fan forced type in which air circulates in the chamber and refrigerant coils are on the back. The latter type is recommended for storage of food and other items. The moisture that condenses due to the cooling of air settles on exterior coils and drains into a tray on top of the motor and evaporates. In the fan forced or true frost free freezer, the ice evaporates with time as the refrigerant coils and fan pull moisture out of the freezer.
