Fundamentals of Food Process Engineering pp Cite as. Cooling is a fundamental operation in food processing and preservation. Removal of heat could involve either the transfer of heat from one fluid to another or from a solid to a fluid, or it could be accomplished by vaporization of water from a material under adiabatic conditions. Knowledge of the principles of heat transfer is an essential prerequisite to the understanding of the design and operation of refrigeration systems. Unable to display preview. Download preview PDF.
Thermodynamic heat pump cycles or refrigeration cycles are the conceptual and mathematical models for heat pump , air conditioning and refrigeration systems. A heat pump is a mechanical system that allows for the transmission of heat from one location the "source" at a lower temperature to another location the "sink" or "heat sink" at a higher temperature. In either case, the operating principles are close. According to the second law of thermodynamics heat cannot spontaneously flow from a colder location to a hotter area; work is required to achieve this. Similarly, a refrigerator moves heat from inside the cold icebox the heat source to the warmer room-temperature air of the kitchen the heat sink. The operating principle of ideal heat engine was described mathematically using Carnot cycle by Sadi Carnot in

Мне не нужно напоминать. Через тридцать секунд она уже сидела за его столом и изучала отчет шифровалки. - Видишь? - спросил Бринкерхофф, наклоняясь над ней и показывая цифру. - Это СЦР.
