Today the refrigerator goes hand in hand with the freezer, the latter serving the purpose of freezing meat, or any other products that require being kept at temperatures below 0 degrees Celsius. Usually freezers are built in compartments found at the top of the refrigerator and the latter can be incorporated in the kitchen furniture or can stand freely. Moreover the refrigerator comes in various sizes for domestic usage. It can be as small as to hold only a six packs of beer cans or as high as a regular human being and with a capacity of up to 600 liters.

You can see these especially in supermarkets and they can hold cartons of milk or other dairy products, various types of ham or other meat products, pre-cooked food, fruits, greens and many others.

Many of those selling products in the marketplace would feel that profit would be more difficult to get because products would spoil more rapidly and customers would not choose to purchase them any longer.

It allows us to buy more food at one time and keep it fresh, especially vegetables or salad ingredients. For those who want to eat healthy, the refrigerator is like a best friend storing greens and fruits for a longer time without the stringent need to pay a visit to the market place. It has facilitated our lives and it has had its share in bringing about more satisfaction in every meal.
