Second law analysis and the application of the efficient power criterion to a four-temperature-level absorption chiller
Absorption chillers are a good option for air-conditioning applications and can be operated by low grade energy which makes them environmentally friendly. Common absorption chillers have four main internal components (generator, evaporator, condenser and absorber) and operate between four …

SIMULATION OF ABSORPTION CYCLES FOR INTEGRATION INTO REFINING PROCESSES
… and gas industry is an immense energy consumer. Absorption chillers can be used to recover liquid natural gas (LNG) plant waste heat to provide cooling, which is especially valuable in the oil and gas industry and would also improve energy efficiency. This thesis details the modeling procedure …

Toward zero net energy buildings : optimized for energy use and cost
… for Design Advisor include: heat pumps, absorption chillers, PV, cogeneration, and cost. Using capital cost above baseline as the independent variable, the tool outputs the net annual energy use and total cost (capital and energy) for each case analyzed in the optimization. This allows …

Development and validation of a thermodynamic model for predicting mode transitions in falling film flows over horizontal tubes
… desalination, vapor compression machines, absorption chillers, and natural gas liquefaction. Falling-film heat and mass exchangers are attractive for these applications because, in comparison to other designs, they provide high transport coefficients with low system charges. As a liquid …

Model based control optimisation of renewable energy based HVAC Systems.
… started to commercialise also small scale absorption cooling machines. However, not all of the installed systems operate efficiently and some are, from the primary energy point of view, even worse than conventional systems with a compression chiller. The main reason for this is a poor …
