Abstract

A study was made of an automatic - and a manual- defrost refrigerator/freezer combination, and an upright and a chest freezer to measure the effect on energy consumption of five variable usage conditions: thermostat setting, ambient temperature, food load, door-opening frequency, and relative humidity. No evaluation was made of the effect of frost build-up. Ambient temperature and thermostat setting were found to have considerably greater effect on energy consumption than door-opening and relative humidity changes for the specimens tested.
