Embodiment Construction

[0022] figure 1 The refrigeration appliance in comprises three storage chambers 1, 2, 3, which are arranged one above the other and / or next to each other in the housing and are thermally insulated two by two from each other and from the surrounding environment. Each storage chamber 1 , 2 , 3 is assigned an evaporator 4 , 5 and 6 respectively. The evaporators 4 , 5 , 6 are of a design known in principle. As shown, this can involve plate evaporators, on the plates 7 of which the refrigerant lines 8 respectively run in a meandering manner, which can be respectively attached to the storage chamber 1, 2, 3 or attached between the inner container of the storage chamber and the thermal insulation surrounding the inner container. However, this may also involve a line-tube or finned evaporator, optionally in combination with a fan driving the air circulation over the evaporator.

[0023] The evaporator 4 is connected upstream with a throttle point 9 with an adjustable conductance va...

Abstract

In the refrigerant circuit of a refrigeration appliance, especially a household refrigeration appliance, between the pressure port (19) and the suction port (17) of the compressor (18) are connected in series in sequence: the condenser (20), the first throttling point (9), the first evaporator (4) for cooling the first storage chamber (1), and the second throttling point (10), wherein, in order to control the pressure in the first evaporator (4), it can be set At least one of the first and second throttle points (9, 10) is determined. The refrigerant circuit comprises: a first branch (11), which includes a first throttling point (9), a first evaporator (4) and a second throttling point (10); and at least one second branch (12 ), which is connected in parallel with the first branch, wherein the third throttling point (13), the second evaporator (5) arranged in thermal contact with the second storage chamber, and the fourth throttling point (14) are connected in series. In order to control the pressure in the second evaporator (5), at least one of the third and fourth throttling points (13, 14) can be set.

Description

technical field [0001] The invention relates to a refrigeration appliance, in particular a domestic refrigeration appliance, which has at least two storage chambers which can be operated at different temperatures. Background technique [0002] In most such refrigerating appliances, the operating temperature of the storage compartments is roughly limited by the construction type of the refrigerating appliance and can only be set in narrow non-overlapping ranges, so that for example the compartments as refrigerating and freezing compartments Possible uses cannot be changed by the user of the refrigeration appliance. [0003] A refrigeration appliance is known from DE 10 2013 223 737 A1, in which the evaporators of two storage chambers are connected in series via a throttling point with an adjustable flow value. The throttling point enables the temperature of the two storage chambers to vary to a relatively large extent. However, the operating temperature of one compartment a...
