The correct temperature for your freezer is 0 degrees Fahrenheit—if you set it to 0 degrees (-18 degrees Celsius) and keep it fairly full, it will maintain that temperature. How to Monitor ...
Although both the three- and four-star ratings specify the same storage times and same minimum temperature of −18 °C (0 °F), only a four-star freezer is intended for freezing fresh food, and may include a "fast freeze" function (runs the compressor continually, down to as low as −26 °C (−15 °F)) to facilitate this.

A standard upright negative 80 degree freezer. An ultra low temperature (ULT) freezer is a refrigerator that stores contents at −80 to −86 °C (−112 to −123 °F). [1] An ultra low temperature freezer is commonly referred to as a "minus 80 freezer" or a "negative 80 freezer", referring to the most common temperature standard. [2]
Increasing the input temperature (e.g. by using an oversized ground source or by access to a solar-assisted thermal bank [10]). Accurately determining thermal conductivity will allow for much more precise ground loop [11] or borehole sizing, [12] resulting in higher return temperatures and a more efficient system. For an air cooler, the COP ...
Colour indicates relative temperature: blue=cold, red is hottest. The heat source (7) is contained entirely within the insulation section (6). A single-pressure absorption refrigerator takes advantage of the fact that a liquid's evaporation rate depends upon the partial pressure of the vapor above the liquid and goes up with lower partial ...
A refrigerating appliance is required to maintain temperatures inside its compartments within specified limits, and to operate (including defrosting) in a specified ambient temperature while using at most a specified amount of electricity; the energy use allowed varies according to volume, number of doors, the function of the various compartments and other parameters.
While this technique was originally applied to the refrigerator compartment, it was later used for freezer compartment as well. A combined refrigerator/freezer which applies self-defrosting to the refrigerator compartment only is usually called "partial frost free" or semi-automatic defrost (some brands call these "Auto Defrost" while Frigidaire referred to their semi-automatic models as ...
