Simulation and performance analysis of a 4-effect lithium bromide-water absorption chiller

Performance simulation has been conducted for a 4-effect lithium bromide-water chiller, capable of substantial performance improvement over state-of-the-art double-effect cycles. The system investigated includes four condensers and four desorbers coupled together, forming an extension of the conventional double-effect cycle; based on prior analytical studies, a parallel flow system was preferred over series flow, and double-condenser coupling was employed, to further improve performance. A modu… more

Simulation and performance analysis of a quadruple-effect lithium bromide-water absorption

In order to investigate the possibility of improving utilization of high temperature heat sources, such as natural gas, for absorption chillers, performance simulation has been conducted for a quadruple-effect lithium bromide-water cycle, capable of substantial performance improvement over state-of-the-art double-effect cycles. The system investigated includes four condensers and four desorbers coupled together, forming an extension of the conventional double-effect cycle; based on prior experi… more

Simulation and performance comparison of LiBr/H{sub 2}O triple-effect absorption cycles

Performance simulation has been carried out for several LiBr/H2O triple-effect cycles using the Absorption Simulation Model (ABSIM) . The systems investigated include the three-condenser-three-desorber (3C3D) cycle, forming an extension of the conventional double-effect cycle; and two cycles which additionally recover heat from the hot condensate leaving the highest temperature condenser by adding the heat to the lowest temperature desorber. These latter two cycles are called Double Condenser C… more

Simulation and performance analysis of triple-effect absorption cycles

Performance simulation has been carried out for several triple-effect cycles, designed to improve utilization of high temperature heat sources for absorption systems and capable of substantial performance improvement over equivalent double-effect cycles. The systems investigated include the three-condenser-three-desorber (3C3D) cycle, forming an extension of the conventional double-effect one; the recently proposed Double Condenser Coupled (DCC) cycle which recovers heat from the hot condensate… more

Simulation and performance analysis of an ammonia-water absorption heat pump based on the generator-absorber heat exchange (GAX) cycle

A computer simulation has been conducted to investigate the performance of an absorption heat pump, based on the Generator-Absorber Heat Exchange (GAX) cycle employing ammonia-water as the working fluid pair. The particular feature of this cycle is the ability to recover heat from the absorber and employ it to partially heat the generator, thus improving the COP. In the present study, a detailed simulation has been conducted of one of the preferred configurations for the cycle. A modular comput… more

United States Department of Energy Thermally Activated Heat Pump Program

The US Department of Energy (DOE) is working with partners from the gas heating and cooling industry to improve energy efficiency using advance absorption technologies, to eliminate chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), to reduce global warming through more efficient combustion of natural gas, and to impact electric peak demand of air conditioning. To assist industry in developing these gas heating and cooling absorption technologies, the US DOE sponsors the Thermally… more

Post licensing case study of community effects at two operating nuclear power plants. Final report, March 1975--March 1976

The social, economic, and political/institutional impacts of two operating nuclear power complexes on two New England communities are studied. The report includes discussions of the study design and objectives, profiles of the towns of Plymouth, Massachusetts, and Waterford, Connecticut, and analysis of the social, economic, and political impacts as observed by members of the ORNL staff. Results are presented from an attitude survey as well as a social impact classification schema devised as a … more

United States Department of Energy large commercial absorption chiller development program

The US Department of Energy (DOE) is working with partners from the gas cooling industry to improve energy efficiency and US competitiveness by using advanced absorption technologies that eliminate the use of chlorofluorocarbons (CFCs) and hydrochlorofluorocarbons (HCFCs), refrigerants that contribute to ozone depletion and global warming. Absorption cooling uses natural gas as the heat source, which produces much lower NO{sub x} emissions than oil- or coal-generated electricity. Gas-fired chil… more

Citizens' Views About the Proposed Hartsville Nuclear Power Plant: A Survey of Residents' Perceptions in August 1975

This report describes the results of a survey conducted in August 1975 among a group of residents of Hartsville and Trousdale County, Tennessee, regarding their views about the nuclear power plant the Tennessee Valley Authority is constructing five miles outside of Hartsville. As part of a longitudinal study of the social impacts of the nuclear facility, the survey was conducted during the planning and pre-licensing phase of the project to address two questions: (1) What factors are related to … more
