Embodiment Construction

[0035] based on Figure 5 The exemplary embodiment shown is a preferred implementation of the invention. However, for a better understanding of the present invention, first another double loop system is explained.

[0036] First, it should be explained that, in accordance with figure 2 Why can't the two compartments be shut off independently in the dual circuit system. A solenoid valve 8 makes it possible to switch between the two circuits. When the freezer compartment 1 is activated, refrigerant is injected into the freezer compartment or its evaporator 3 and is sucked directly from there to the compressor 5 . In contrast, when the refrigerated compartment is activated, refrigerant is injected into the refrigerated compartment evaporator 4 . There, however, it is conducted to the freezer compartment evaporator 3 and sucked through the entire freezer compartment evaporator 3 to the compressor 5 . This means that when the refrigerated compartment is activated, the freezer...

Abstract

The aim of the invention is to design a cooling appliance, in particular a combined household refrigerator / freezer which has a simple structure and in which each of at least two compartments can be individually switched off. Said aim is achieved by a cooling appliance comprising a cooling cycle that encompasses a compressor (5), a condenser (6) with a cooling conduit (60) that is connected to the compressor (5) at the first end (61), a first valve (11) that is connected to the second end (62) of the cooling conduit (60) of the condenser (6), a first evaporator (3) that is arranged downstream of the first valve (11) and is connected to the compressor (5), and a second evaporator (4). A second valve (10) is arranged between the two ends (61, 62) of the cooling cycle (60) of the condenser (6) and is connected to the second evaporator (4) by means of a second outlet (10b). The second evaporator (4) is connected to the compressor (5) at the outlet end. It is thus advantageously possible to design a simple dual cycle system comprising a single compressor while the amount of coolant can be adjusted to the condenser, or vice versa, because coolant is stored in the second portion (6b) of the condenser (6), resulting in greater energy efficiency.

Description

technical field [0001] The invention relates to a refrigeration appliance having a cooling circuit comprising: a compressor; a condenser having a cooling conduit connected at its first end to the compressor; a first valve , the first valve is connected to the second end of the cooling conduit of the condenser; a first evaporator is disposed downstream of the first valve and is connected to the compressor; and a second evaporator. The invention also relates to a method for cooling a first compartment and a second compartment of a refrigeration appliance having a condenser in which a refrigerant is condensed. Background technique [0002] Modern combined refrigerator / freezers are basically of three types. In a first embodiment, the cooling effect is based on figure 1 Achieved by a single loop system. The combined refrigerator / freezer has a freezer compartment 1 and a refrigerator compartment 2 (in figure 1 , also shown as GS: freezer and KS: freezer). The first evaporator...
