Energy consumption testing of innovative refrigerator-freezers.

Author(s) : WONG M. T., HOWELL B. T., JONES W. R., LONG D. L.

Summary

The refrigerator-freezer technology assessment (RFTA) test was developed to more accurately predict field consumption. This test has ambient temperature and humidity, door openings, and condensation control set at levels intended to typify Canadian household conditions. It also assesses consumption at exactly defined compartment rating temperatures. Ten conventional and energy-efficient production models were laboratory tested. The RFTA results were about 30% lower than labelled. Similarly, the four innovative refrigerator-freezer models, when field tested, also had an average of 30% lower consumption than labelled. Thus, the results of the limited testing suggest that the RFTA test may be a more accurate predictor of field use. Further testing with a larger sample is recommended. Experimental results also indicated that some innovative models could save up to 50% of the energy consumption compared with similar conventional units.
