Abstract:
Two refrigerator-freezers, one with a top-mounted
freezer and one with side-by-side doors, were tested in
the laboratory to determine the sensitivity of their
energy consumption to various operational factors. Room
temperature, room humidity, door openings, and the
setting of the anti-sweat heater switch were the factors
examined. The results indicated that the room
temperature and door openings had a significantly
greater effect on energy consumption than the other two
factors. More detailed tests were then performed under
different room temperature and door-opening
combinations. The relationship of door openings and the
equivalent test room temperature was established.
Finally, the effect on energy of different temperature
settings was studied. Test results are presented and
discussed.
