Small refrigerators vary in their energy efficiency, with some small refrigerator models using as much or more energy than a full-sized model. Small refrigerators typically use more energy in warmer rooms than full-sized refrigerators.
Small refrigerators dispel heat through their exterior walls, whereas full-sized refrigerators contain an external fan and condenser. Therefore small refrigerators are more heat-sensitive than larger models. Because of this, it is better not to place small refrigerators in corners, small spaces or cabinets. Small refrigerators should also be kept away from radiators and other heating devices for optimal energy efficiency. Careful placement of a small refrigerator can reduce the amount of energy it uses.
