Commercial refrigeration. Refrigeration is any of various types of cooling of a space, substance, or system to lower and/or maintain its temperature below the ambient one (while the removed heat is ejected to a place of higher temperature). [1] [2] Refrigeration is an artificial, or human-made, cooling method. [1] [2]
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump, air conditioning and refrigeration systems. [1] A heat pump is a mechanical system that transmits heat from one location (the "source") at a certain temperature to another location (the "sink" or "heat sink") at a higher temperature. [2]
Food in a refrigerator with its door open. A refrigerator, commonly shortened to fridge, is a commercial and home appliance consisting of a thermally insulated compartment and a heat pump (mechanical, electronic or chemical) that transfers heat from its inside to its external environment so that its inside is cooled to a temperature below the room temperature. [1]
Figure 2: Left: (near X 2): a gas element enters the tube with temperature T L and leaves it with a lower temperature. Right: (near X 3): a gas element enters the tube with temperature T H and leaves it with a higher temperature. The part in between X 1 and X 3 is thermally insulated from the surroundings, usually by vacuum. The pressure varies ...
Glycol chillers are a specific kind of refrigeration system, often used to cool a variety of liquids, including alcohol and other beverages. Using a chiller allows producers to lower the temperature of the product dramatically over a short period of time, depending on the production needs.
That means that, to reduce the temperature by a factor 2, one needs to increase the diameter by a factor of 8 and the length by a factor of 256. Hence the volume should be increased by a factor of 2 14 = 16,384. In other words: every cm 3 at 2 mK would become 16,384 cm 3 at 1 mK. The machines would become very big and very expensive.
A cascade refrigeration cycle is a multi-stage thermodynamic cycle. An example two-stage process is shown at right. (Bottom on mobile) The cascade cycle is often employed for devices such as ULT freezers. [1] In a cascade refrigeration system, two or more vapor-compression cycles with different refrigerants are used.
The fundamental principle was suggested by P. Debye (1926) and W. Giauque (1927). [6] The first working magnetic refrigerators were constructed by several groups beginning in 1933. Magnetic refrigeration was the first method developed for cooling below about 0.3 K (the lowest temperature attainable before magnetic refrigeration, by pumping on 3
