Multi-effect absorption chillers

International Journal of Refrigeration, 1993
Abstract Multi-effect absorption heat pump cycles are promising to yield cooling performances which far exceed the performance of single-stage cycles. In this paper, several types of cycles are analysed. For this purpose, the respective multi-effect cycle is decomposed into elementary building blocks of single-stage absorption cycles with known ...

Performance of a Residential-Sized GAX Absorption Chiller

Journal of Energy Resources Technology, 1998
This research effort involved experimentally testing an advanced-cycle, ammonia-water absorption chiller with a cooling capacity of 17.6 kW (5 refrigeration tons (RT)). The system was a generator-absorber heat exchange (GAX) cycle and was sized for residential and light commercial use, where very little absorption equipment is currently used.

Feasibility Study of the Absorption Chiller Integration

Applied Mechanics and Materials, 2015
Paper presents feasibility study of the absorption chiller integration. In the search model system of air conditioning uses absorption chiller instead of the standard vapor compression chiller due to the fact of insufficient electrical supply of the building. Calculated payback periods show limits of the effective applying of the absorption chiller.

Absorption chillers applied to CHP systems

Building Services Engineering Research and Technology, 1995
The parameters that should be considered at the design stage of a combined heat and power (CHP) project have been determined for situations when absorption refrigeration is to be used. Single and double stage chillers are considered together with system features such as hot water, steam or heat recovery driven, in terms of the hot temperature heat ...

Simulation of an ammonia–water absorption chiller

Renewable Energy, 2013
Abstract An increased interest in absorption chillers has been observed [1] because these systems can utilize solar, geothermal and biomass energy sources, but also because they are quiet, vibration-free, require little maintenance and are ecological [2] .

Theoretical and experimental analysis of an absorption chiller

International Journal of Refrigeration, 1994
Abstract A theoretical model for the performance of an absorption chiller has been derived using thermodynamic laws. From the model, a non-dimensional temperature ratio, T ∗ , is proposed. It relates to the water temperatures that are supplied to the condenser and the evaporator of an absorption chiller.

Experimental report on the reliability of ammonia-water absorption chillers

International Journal of Refrigeration, 1996
Abstract The analysis of a large amount of data on the failures of absorption refrigeration machines of the ammonia-water type was carried out. The data derive from the records of a 10-year maintenance contract under which every machine was installed.
