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]
A bagel (Yiddish: בײגל, romanized: beygl; Polish: bajgiel [ˈbajɡʲɛl] ⓘ; also spelled beigel) [1] is a bread roll originating in the Jewish communities of Poland. [2] Bagels are traditionally made from yeasted wheat dough that is shaped by hand into a torus or ring, briefly boiled in water, and then baked. The result is a dense, chewy ...
The operating principle of the refrigeration cycle was described mathematically by Sadi Carnot in 1824 as a heat engine. The most common types of refrigeration systems use the reverse-Rankine vapor-compression refrigeration cycle, although absorption heat pumps are used in a minority of applications. Cyclic refrigeration can be classified as:
Isaac’s Bagels have gained a following for their no-frills, New York-style bagels. They’re what Durham’s been waiting for. Isaac’s Bagels sell out for a reason.
1864 – Charles Tellier patented a refrigeration system using dimethyl ether; 1867 – Thaddeus S. C. Lowe patented a refrigeration system using carbon dioxide, and in 1869 made ice making machine using dry carbon dioxide. The same year Lowe bought a steamship and put a compressor based refrigeration device on it for transport of frozen meat.
In refrigeration systems, subcooling the refrigerant is necessary to ensure the completion of the remaining stages of the refrigeration cycle. The subcooling stage provides certainty that the refrigerant is fully liquid before it reaches the next step on the cycle, the thermal expansion valve, where the presence of gas can be disruptive.

Companies like Junior's Cheesecake and bagel shops are reporting cream cheese shortages as supply chain issues persist and consumption rises. Cream cheese shortage: Supply chain problem has ...
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.
