absorption cycle

absorption cycle

[əb′sȯrp·shən ‚sī·kəl]
(mechanical engineering)
In refrigeration, the process whereby a circulating refrigerant, for example, ammonia, is evaporated by heat from an aqueous solution at elevated pressure and subsequently reabsorbed at low pressure, displacing the need for a compressor.

A design procedure was applied to a lithium bromide absorption cycle and an optimization procedure that consists of determining the enthalpy, entropy, temperature, mass flow rate, and heat rate in each component and coefficient of performance was calculated.
The new freeze-drier uses modern industrial automation processes and a cold generation system through an absorption cycle, which allows more technical reliability and operation at lower temperatures during freeze-drying.
The most basic components of a vapour absorption cycle are the evaporator, absorber, pump(s), generator (or desorber), a condenser and throttle valves (4-5).
They use "an ammonia-water absorption cycle to provide heating and, if it's a reversible heat pump, cooling" explains Christina Kielich, spokesperson for the U.
2) Bromeliads, many orchids, and easy-to-care-for succulents such as jade plants intensify their oxygen production/carbon dioxide absorption cycle at night.
The liquid sorption cycle refers to the absorption cycle, and the solid sorption cycle refers the adsorption cycle.
Taking these observations in conjunction with changes in the respective dynamic mechanical spectra obtained on the dried samples after the first absorption cycle, shown in Fig.
It is found that refrigeration output at the ejector, cascaded refrigeration and heating increases while refrigeration output in absorption cycle and total output decreases with increasing industrial waste gas temperature.
The simulation of the whole absorption cycle is based in two levels of modeling: (1) the cycle modeling level, where the main overall values of the cycle are calculated, and (2) the heat exchanger detailed modeling level, where the overall heat transfer coefficients and the subcooling values at the outlet of the heat exchangers, needed by the above-mentioned cycle modeling level, are calculated using the input data of the experimentation.
Our revised expectations are a result of a challenging service provider and global carrier business environment, brought about by a capacity absorption cycle taking place currently throughout the industry.
The Duhring diagram of a conventional absorption cycle is shown in Fig.
