It is a home appliance which is used to store food and other items that are required to be put or stored in a cool temperature. Refrigerator is an appliance that consists of a thermal insulated compartment and a heat pump which can be mechanical, electrical or chemical that transfer heat inside the compartment and cool it down or below the external temperature outside the compartment. Preferred temperature inside the compartment of the refrigerator is 0°C to 8°C.
The preferred temperature range of the refrigerator compartment is 3°C to 7°C for perishable foods like milk, butter, bread, fresh fruits and vegetables, above 7°C perishable foods items start to deteriorate quickly. So lower the temperature lowers the reproduction of bacteria. A refrigerator usually maintains the temperature in the compartment a few degrees above water’s freezing point, which is 0°C. A refrigerator is not an appliance that is for frozen foods items but only to cool down the temperature. A freezer is an appliance which is similar to a refrigerator but it maintains a temperature below the freezing point of water.
