Case Study Walnut Hill United Methodist Church - Dallas, Texas, Chiller Replacement Analysis
Abstract
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.
