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 above systems produce an economizer effect by using compressors, meters, valves and heat exchangers within the refrigeration cycle. In some refrigeration systems the economizer can be an independent refrigeration mechanism. Such is the case of subcooling the liquid line by any other means that draws the heat out of the main system. For ...
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]
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:
The ionocaloric refrigeration cycle is an advanced cooling technology that utilizes the ionocaloric effect, driven by an electrochemical field, to achieve efficient and eco-friendly refrigeration. By manipulating the electrochemical potential through ion addition or removal, significant temperature changes and entropy variations are achieved.
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.
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 ...
The most common refrigeration cycle is the vapor compression cycle, which models systems using refrigerants that change phase. The absorption refrigeration cycle is an alternative that absorbs the refrigerant in a liquid solution rather than evaporating it. Gas refrigeration cycles include the reversed Brayton cycle and the Hampson–Linde cycle.
