Summary

Societal demands to control climate change are driving the development of many Life Cycle Climate Performance (LCCP) tools to understand how to minimize the total environmental impacts of HVACR products. The LCCP models can be extremely detailed, accounting for all CO2 contributions from CO2 emissions from the use of energy (indirect) and CO2 equivalent emissions from other operations (direct CO2eq) from "cradle" (refrigerant and product manufacturing), through use (including servicing and potential leak rates by type of product), to "grave" (recycling and disposal) for a product. LCCP tools have been developed for a number of HVACR product segments and continue to grow in number (GREEN-MAC-LCCP; ORNL Supermarket LCCP; AHRI HP LCCP; Zhang, et al., 2011). However, there are few studies into understanding how the results from these various tools compare to each other against the latest available lower Global Warming Potential (GWP) next generation refrigerant technology. Because global regulatory discussions currently are focusing on reducing direct GWP contributions of refrigerants and for the most part are ignoring their impact on indirect GWP contributions as refrigerant choices are considered, there is potential for regulators to reduce the available refrigerant choices that would allow manufacturers all the tools available to minimize the total environmental impact (lowest LCCP) through maximum efficiency and maintaining the maximum sustainability and safety for consumers. This paper will provide LCCP assessments with the latest available refrigerant technology for stationary refrigeration, transport refrigeration, unitary air conditioning, and chiller air conditioning product segments. This paper will suggest GWP limits for refrigerants by application, since direct GWP limits may need to be defined by application type based on the available refrigerant technology to minimize environmental impacts.
