What is refrigerator?


    A refrigerator is a machine for keeping things cold. It is sometimes called a fridge or an icebox. People put food and drinks in it, to keep those items cold or good (unspoiled) for a longer time. In the refrigeration cycle,  there are five basic components: (i) fluid refrigerant; (ii) a compressor, which controls the flow of refrigerant; (iii) the condenser coils (on the outside of the fridge); (iv) the evaporator coils (on the inside of the fridge); and (v) something called an expansion device. In general, a refrigerator can be seen as a heat pump. It takes heat away from the air inside the fridge. The heat gets added to the air from outside. For this, it usually uses electricity.

    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. These 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 colors, although normally fridges are white.
