The authors propose a solar cooling system employing a steam-driven triple effect absorption chiller as a new technique for saving CO2 emission in the air conditioning field. The absorption chiller is a cooling machine using thermal energy as a drive source, and it is ideal for utilizing solar heat. In addition, by employing a triple effect absorption chiller of high efficiency, a high energy s...

the first and second laws of thermodynamics have been employed to evaluate energy and exergetic efficiency of the single effect absorption chiller which is used for air conditioning purpose. the performance analysis has been carried out by developing a computer program in ees and modeling the chiller and its components. to evaluate entropy of the water/lithium bromide solution at any point, an ...

There are extensive applications of lithium bromide-water absorption chillers in industry, but the heat exchangers corrosion and refrigerating capacity loss are very difficult to be solved. In this paper, an experiment was conducted by using plastic heat transfer tubes instead of copper tubes. As an example, for a lithium bromide-water absorption chiller of refrigerating capacity of 35kW, the c...

To minimize environmental impact and CO2 production associated with air-conditioning system operation, it is reasonable to evaluate the prospects of a clean energy source. Solar energy can drive an absorption chiller in order to satisfy the cooling needs of buildings. The objective of this work is to build a simulation environment that can evaluate accurately the energy consumption of an air co...

A dynamic model for the simulation of a new single-effect water/lithium bromide absorption chiller is developed. The chiller is driven by two distinct heat sources, includes a custom integrated falling film evaporator-absorber, uses mixed recirculation and is exclusively cooled by the ambient air. Heat and mass transfer in the evaporator-absorber and in the desorber are described according to a...

The Broad Two Stage, Steam Driven Absorption Chiller

The optimal use of electrical and fuel energy in a chiller system, like absorption chiller system, is important in achieving economical system operation. The related research work, including the derivation of a thermal model for the system by an integration of component models can be a tedious task, based on the technology today. The numerous assumptions associated with the governing equations ...
