electric refrigerators, at least in suitable climes, should be vented outside in warm weather and use cold air from the outside in cold weather. to have refrigerator compressors laboring in extracting cold air from air we have paid to heat when the outside environment is often colder than the refrigerator seems like a waste of energy. vented outside in hot weather and utilized in the refrigerator in cold weather seems to make sense to me. in warm weather we pay for cooling the air with an air conditioner and then the refrigerator pours the hot air from cooling the box into the house to raise the demand of the air conditioner. that also does not make sense excepting to those who benefit by selling electriciity.
