What is refrigerator:
Refrigerator is an appliance that cools an area, generally for food, beverage or vaccine storage. A refrigerator (or fridge), can be powered by electricity, propane, gas or kerosene. Refrigerators lower the temperature, and therefore, even evaporative coolers can be considered refrigerators. Many refrigerators also include a freezer, and are often referred to as "fridge/freezers".
