Problems solved by technology

This can lead to dysfunctional or unwanted noise
Also, the additional connection points caused by installing the valve into the refrigerant circuit is a further problem with such valves
On the one hand, it is expensive and poses the danger of potential leakage
Furthermore, due to these valves, relatively high component costs result

Embodiment Construction

[0023] figure 1 shows a refrigerating and / or freezing device 1 , the body 2 of which can be closed by a through door 3 . The inner space of the body 2 is divided into a freezer compartment 4 and a refrigeration compartment 5. As shown in the embodiment, the freezer compartment 4 can be closed by an inner door 6, and the storage rack 7 and the drawer type vegetable basket 8 are arranged in a known manner. In the refrigeration chamber 5.

[0024] The freezer compartment 4 is cooled by a freezer compartment evaporator 9 which can surround the freezer compartment on five sides. On the contrary, the refrigeration compartment 5 is cooled by the refrigeration compartment evaporator 10 extended on the rear wall surface of the refrigeration compartment 5 .

[0025] Such as figure 2 As shown, the freezer compartment evaporator 9 and the refrigeration compartment evaporator 10 are part of a refrigerant circuit 11 which also includes a compressor 12, a condenser 13, and a capillary tu...

Abstract

The present invention relates to a refrigerator unit and / or freezer unit comprising a refrigerant circuit, which has a compressor, a condenser, at least one capillary tube as well as at least one evaporator, and a control device for the control of the refrigerant flow through the refrigerant circuit. The invention further relates to a method for the control of such a refrigerator unit and / or freezer unit, wherein at least one operating parameter and / or ambient parameter of the refrigerator unit and / or freezer unit is detected and the refrigerant flow is controlled by the refrigerant circuit in dependence on the detected operating parameter and / or ambient parameter. It is proposed in accordance with the invention to control the refrigerant flow in that the capillary tube is heated by meansof a heating device and thereby causing the refrigerant flowing through the capillary tube to evaporate. The invention is based on the recognition that vapor produced in the capillary tube can considerably reduce and optionally completely prevent the flow of the refrigerant through the capillary tube. The greater the evaporation produced in the capillary tube, the lower the remaining refrigerant flow through the capillary tube.

Description

technical field [0001] The invention relates to a refrigeration device and / or freezing device comprising a refrigerant circuit having a compressor, a condenser, at least one capillary tube and at least one evaporator, and a control device for controlling the flow through Refrigerant flow in the refrigerant circuit. [0002] The invention further relates to a method for controlling such a refrigerating and / or freezing device, wherein at least one operating parameter and / or environmental parameter of the refrigerating and / or freezing device is detected and then operated according to the detected Parameters and / or ambient parameters control the flow of the refrigerant through the refrigerant circuit. Background technique [0003] Typically, valves such as monostable or bistable solenoid valves or motor-driven valves are used to control the flow of refrigerant in a refrigerant circuit of a refrigeration and / or freezer. For example DE 3601817 A1 discloses a regulating device fo...
