Case Study Walnut Hill United Methodist Church - Dallas, Texas, Chiller Replacement Analysis
In March of 1992 Walnut Hill United Methodist Church in Dallas, Tx. decided that their existing thermal storage and electric reciprocating chiller system were both in need of replacement. After analyzing several options, they chose to install 150 tons of gas-fired double-effect absorption chillers. This case study will show the original HVAC operation cost analysis and compare it to the present day operation costs and it will describe how unexpected changes occurred that caused the initial analysis to be questioned. Finally, this case study will show how today's operational costs are lower than originally projected. This presentation is not about the reasons the church chose this particular system, but about the analysis itself and its accuracy.
