Refrigerators

The Samsung RF197AC[WP] is part of the refrigerator test program at Consumer Reports. In our lab tests, bottom freezer refrigerator models like the RF197AC[WP] are rated on multiple criteria, such as those listed below.

Temperature performance:

This combines results of tests measuring the accuracy of initial temperature settings along with how well a model 1) kept optimum temperatures in the refrigerator and freezer at the same time; 2) kept temperatures even throughout each compartment; 3) kept temperatures constant despite changes in room temperatures; and 4) maintained set temperatures even with very high room temperatures.

Energy efficiency:

This reflects electricity consumption (based on our tests) per cubic foot of measured usable storage space. For example, two models with the same energy cost per year may have different energy efficiencies -- the unit with more storage space being more efficient.

Noise:

Noise level was measured when the compressor started up and during steady running. Subjective judgments by a panel of listeners supplemented our noise-meter readings.
