why do we need refrigerators?

One of the best methods of preserving foods is refrigeration. It is the process of cooling or freezing (e.g., food) for preservative purposes. Today, in almost all households, a refrigerator is a must. A refrigerator often called a "fridge" for short is a cooling appliance comprising a thermally insulated compartment and a mechanism to transfer heat from it to the external environment, cooling the contents to a temperature below ambient. Refrigerators are extensively used to store foods which deteriorate at ambient temperatures; spoilage from bacterial growth and other processes is much slower at low temperatures. If you're thinking of purchasing one for yourself right now, do try the Whirlpool Refrigerators. They have a wide variety of models to choose from. You should have one if you want to make sure that your food is stored safely and properly.
