Refrigerator having a microprocessor-controlled temperature regulation

摘要

In this it is proposed to control the cool-space temperature of a refrigerator which is designed with a normal refrigerator section (1) and a freezer section (2), a one-circuit refrigerant circulation, a compressor refrigeration unit (3), a condenser (6), a throttle member and in each case an evaporator part (4, 5) for the freezer section and the normal refrigerator section. An electronic control unit (8) ensures the regulation of the temperature of the interior space, a temperature sensor (9) being arranged in the normal refrigerator section (1) and a further temperature sensor (11) in the freezer section (2). The microprocessor-controlled control unit (8) is supplied with the temperature values from the interior space of the normal refrigerator section (1), directly from the evaporator part (4) of the normal refrigerator section (1), and from the interior space of the freezer section (2). When the temperature in the freezer section (2) exceeds a predetermined value, a recirculation air blower (12) is switched on for circulating the air in the normal refrigerator section (1). As a result, the temperature in the freezer section (2) is always held at permissible temperature values even in the case of extremely unfavourable outside temperatures or when the user has preset the desired value at a value which is too high. <IMAGE>
