The benefits of integrated chiller retrofits: Excerpts from case studies
An integrated chiller retrofit is an effective way to turn the CFC phaseout into an opportunity for energy efficiency and money savings. The 1996 moratorium on CFC production means many chillers will soon have to be replaced or converted to use alternative refrigerants. Integrating building load reductions and system improvements with chiller replacements and/or conversions can solve building comfort and maintenance problem, increase energy efficiency, save money on utility bills, increase a building's asset value, and produce a more financially attractive project. The poll $ense program at Lawrence Berkeley National laboratory has been gathering integrated chiller retrofit case studies from its regional workshops. This paper presents some of the best examples of different aspects of integrated retrofits. Example projects include: (1) a chiller conversion, (2) a chiller replacement, (3) an effective cooling system renovation, (4) a model building load reduction scheme, (5) an illustration of integrated chiller retrofit economics, (6) a chiller sizing cautionary tale, and (7) an environmentally friendly and cost-effective retrofit. These projects enumerate retrofit measures to consider, and show how much more effective it is to widen your focus from the chiller alone to the entire building when facing the CFC phaseout.
