### This spreadsheet evaluates the change in the energy use measurement associated with variation in compartment temperatures for different parts of the icemaking test. The calculations are based on test results reported in NIST Technical Notes 1697 and 1759. Data for 2011 Samples 3 and 4 are provided in the first of these Technical Notes, while data for 2012 Samples 1 and 2 are provided in the second Technical Note. NIST provided energy use and ice production data for each of the four evaluated refrigerator-freezers at three temperature setting combinations which allows use of the triangulation method to calculate energy use and ice production rate for selected compartment temperatures. The spreadsheet uses this information to determine the total energy use based on 1.8 lb/day ice production for each refrigerator-freezer when compartment temperatures are equal to the standardized temperatures (39°F for the fresh food compartment and 0°F for the freezer compartment), and also for tests in which (a) compartment temperatures for baseline and icemaking tests deviate the same amount from the standardized temperatures, and (b) compartment temperatures match the standardized temperatures for the baseline tests but deviate for the icemaking tests. The defrost energy use for the 2012 Samples is estimated as 4.5 percent of the energy use of the product not including defrost and icemaking energy use, since the NIST report does not provide defrost energy use measurements for these units. This 4.5 percent is the average fraction of energy represented by defrost for the 2011 unit tests.
