Embodiment Construction

[0018] figure 1 The refrigerator shown schematically in , comprises an insulated housing 1 with at least one refrigerated compartment, and an evaporator 2 assigned to the refrigerated compartment. In the refrigerant circuit, the evaporator 2 is connected to a compressor 3 driven by a motor, and a condenser 4 . An evaporator 2, for example in the form of a cold-wall evaporator, can be arranged next to the refrigerating compartment, wherein, in this case, a fan 5 freely arranged in the refrigerating compartment is provided for cooling along the The walls of the refrigerated compartment drive the air flow. This may be a no-frost evaporator housed in a chamber displaced from the refrigerated compartment, wherein, in this case, a fan 5 is provided in the passage between the chamber and the refrigerated compartment to Facilitates air exchange between the two.

[0019] The control unit 6 is connected to a temperature probe 7 located in the refrigerated compartment, and a probe 8 l...

Abstract

The invention relates to a refrigerator, comprising a compressor (3), a condenser (4) and an evaporator (2), connected in a refrigerant circuit. The evaporator (3) is forced-ventilated by a fan (5) of adjustable power. A controller (6) is designed to regulate the power of the fan (5) in the opposite sense to a heat load on the refrigerator.

Description

technical field [0001] The invention relates to a refrigerator with a compressor, a condenser and an evaporator connected in a refrigerant circuit, wherein the evaporator is forced to ventilate by means of a fan with adjustable output. Such a refrigerator is known from DE 10139834 A1. Background technique [0002] In this known refrigerator, two evaporators cooling two compartments of the refrigerator are connected in series in a refrigerant circuit, wherein a fan is assigned to one of the two evaporators. Selective operation or non-operation of the fan during compressor operation will create the opportunity to regulate the distribution of air to the two compartments. This takes into account the fact that compartments kept at various temperatures have a demand-to-cooling power ratio that varies with ambient temperature. If the appliance is operated in a hot environment, both compartments require considerable cooling power; in a cold environment, the hotter of the two compa...
