Temperature settings for refrigerator and freezer compartments are often given arbitrary numbers by manufacturers (for example, 1 through 9, warmest to coldest), but generally 3 to 5 °C (37 to 41 °F) [3] is ideal for the refrigerator compartment and −18 °C (0 °F) for the freezer. Some refrigerators must be within certain external ...
Haier was founded as Qingdao Refrigerator Co. in 1984. With China opening up to world markets, foreign corporations began searching for partnerships in China. One of these, Germany's refrigerator company Liebherr, entered into a joint-venture contract with Qingdao Refrigerator Co., offering technology and equipment to its Chinese counterpart.
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 ...
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] ULT freezers come in upright and chest freezer formats.
Zhang Ruimin was born on January 5, 1949, to a working class family in Qingdao, Shandong; his parents were employed in a local garment factory. [5] As a youth, Zhang joined the Red Guards, visited Mao's birthplace, and attended rallies in Beijing since all schools had been closed, and when the movement was finally disbanded, he was able to avoid being sent down to the countryside.
Peltier coolers are often used where a traditional vapor-compression cycle refrigerator would be impractical or take up too much space, and in cooled image sensors as an easy, compact and lightweight, if inefficient, way to achieve very low temperatures, using two or more stage peltier coolers arranged in a cascade refrigeration configuration ...
Since the MCE occurs below room temperature these materials would not be suitable for refrigerators operating at room temperature. [13] Since then other alloys have also demonstrated the giant magnetocaloric effect. These include Gd 5 (Si x Ge 1−x) 4, La(Fe x Si 1−x) 13 H x and MnFeP 1−x As x alloys.
A pot-in-pot refrigerator, clay pot cooler [1] or zeer (Arabic: زير) is an evaporative cooling refrigeration device which does not use electricity. It uses a porous outer clay pot (lined with wet sand) containing an inner pot (which can be glazed to prevent penetration by the liquid) within which the food is placed.
