Method for controlling the moisture content of the air in a domestic frost-free refrigerator/freezer has a selector switch to vary the switching of the fan and compressor

摘要

The refrigerator section (1) has an evaporator section (5) in a space (8) from which air is drawn by a fan (9) to remove moist air to prevent condensation frost. The compressor (3) and fan are switched by a control unit (10) with a selector switch (11) to run the fan and compressor in three different modes. The normal mode has the two units operating simultaneously, but for greater moisture reduction the compressor may be operated more frequently than the fan and for more rapid cooling the fan may not be operated at all.
