Figure 14 shows an LCCP analysis for a R410A 3-ton H/P with 13.0 SEER and 7.7 HSPF meeting current DOE regulation in comparison to R32 and the other three HFO blends tested as well as pure R1234yf for comparative reference. As can be seen, the direct component with R410A is only about 5% of the total emission even assuming a conservative 4% annual leak rate and 30% end-of-life loss and 15 year life. The indirect component is based oncalculating the changes in SEER and HSPF based on the four tests and using 0.65 kg CO2/kwh representative of the US average power plant emission rate. Consequently, the overall LCCP index as shown at the bottom of the chart is reduced less than 5% indicating it is better to reduce the indirect content through efficiency. The direct content would increase about 3x to 15% for a trophy H/P like 20+SEER/12.0 HSPF where the charge could be 2x higher and the indirect content is 35% less, but this trophy segment is less than 2% of the market. It is interesting to note that there is diminishing return pursuing only the GWP since the direct content is < 1.5% with 675 GWP of R32. Another good example is R1234yf has same LCCP as R410A baseline despite having a GWP of 4 due to its higher indirect trading off the lower direct content.
