Here are some things you should consider when choosing your new fridge. Energy Usage: Depending on the age of your current fridge, you'll likely lower your energy usage no matter what replacement ...
A cooling zone in the refrigerator door shelves. Air from the freezer section is diverted to the refrigerator door, to cool milk or juice stored in the door shelf. A drop down door built into the refrigerator main door, giving easy access to frequently used items such as milk, thus saving energy by not having to open the main door.
The label must show the model number, the size, key features, and display largely a graph showing the annual operating cost in range with similar models, and the estimated yearly energy cost. [ 2 ] [ 3 ]
Direct cool is one of the two major types of techniques used in domestic refrigerators, the other being the "frost-free" type. Direct-cool refrigerators produce the cooling effect by a natural convection process from cooled surfaces in the insulated compartment that is being cooled. Water vapor that contacts the cooled surface freezes.
Appliances and equipment that qualify to carry the energy star mark are generally in the top 25% most energy efficient products. In Australia, the label is used for office equipment and home electronics. New Zealand uses the energy star label for a much wider range of products such as whitegoods, lighting, heating, water heating and windows. [1]
The Fridge Gate method is a theoretical application of using a single logic gate to drive a refrigerator in the most energy efficient way possible without violating the laws of thermodynamics. It operates on the fact that there are two energy states in which a particle can exist: the ground state and the excited state.
