Description

District cooling plants using large electric-powered water-cooled vapor compression machines in warm weather regions are gaining popularity, providing an economic mass scale cooling for buildings. This paper proposes to replacesuch a system with the use of direct-fired two-stage absorption chillers located at the power generation plant. Absorbers energized by the exhaust of a gas turbine power generation plant can be used to provide chilled water to cool nearby buildings.Calculations are included that demonstrate how the carbon footprint can be reduced and the economic gains involved. Also included is a sustainable design approach addressing environmental,economic, and social aspects.The methodology is as follows: A stepped schematic procedure was adopted to show how calculations were carriedout. Industrial gas turbine engine data were used in conjunctionwith standard data and equations given in ASHRAE standards.Calculations presented in this document can be used toanalyze the feasibility of such an investment.The results were obtained and analyzed on sustainablebases, discussing the environmental, economic, and socialgains associated with such a design.The analysis demonstrates how such a system can be sized,how sustainable energy development can be achieved withsubstantial reductions in the carbon footprint, and the profitgains. Equations were developed assessing capital investmentreturns and generated profits, providing a guide on the feasibilityof such investments.
