HOME APPLIANCE – REFRIGERATOR

A refrigerator is a machine used for keeping things cold. It is sometimes called a fridge or an icebox. It is normally maintained at 4-5 degree Celsius for household use. People put food and drinks in it, to keep those items cold or good for a longer time. A refrigerator has a heat pump which takes heat away from the air inside the fridge. The heat is moved to the air outside. The heat pump is usually driven by an electric motor.

There are also ice boxes available that do not use electricity because they are filled with ice to provide the colder temperature. The ice can keep things cold until the ice melts. Ice boxes can be taken on camping trips. Sometimes they are called coolers. Refrigerator-sized iceboxes were used before electricity was available.

Most modern refrigerators are available in a variety of colours, although most are white. Smaller versions of the popular refrigerator are also used. They are mainly used in hotels and college dorm rooms.

A freezer is a special type of refrigerator that stores food at freezing temperatures. Inside a freezer, it is normally −18 °C (0 °F). Freezers can be found in household refrigerators, as well as in industry and commerce. When stored in a freezer, frozen food can be stored safely for a longer time than storing at room temperatures.

Nowadays we are in a hectic world, no-one has time to prepare food for time to time. So that the refrigerator plays a vital role in our day to day life. In early times, it is used only to preserve the easily spoiled food items for longer time. But we are using it to store all the food remains, and use it for the next meal. Although it is not good for health, we are used to it. Let’s be acknowledged and minimize the use of refrigerators.

BE COOL BUT BE HEALTHY
