Embodiment Construction

[0025] figure 1 Shows a schematic diagram of a refrigeration appliance 100, the refrigeration appliance 100 has a first refrigeration compartment 101-1 for storing cooled items at a first temperature, such as a refrigeration compartment and a second refrigeration compartment for storing cooled items at a second temperature. Grid 101-2, such as a frozen grid.

[0026] The refrigeration appliance 100 is used, for example, to cool food and comprises a refrigerant circuit with an evaporator, a compressor, a condenser and a throttling device. The evaporator is a heat exchanger in which the expanded liquid refrigerant evaporates by absorbing heat from the medium to be cooled, ie the air located in the refrigeration appliance.

[0027] A compressor is a mechanically operated component that draws refrigerant vapor from the evaporator and outputs it at higher pressure to the condenser. A condenser is a heat exchanger in which compressed vapor refrigerant is condensed by releasing hea...

Abstract

The invention discloses a refrigeration device having a plurality of refrigeration compartments. The present invention relates to a refrigeration device (100) having a first refrigeration compartment (101-1) for storing refrigerated goods at a first temperature, said first refrigeration compartment comprising a first evaporator (103-1) with a first controllable expansion valve (105-1) at the refrigerant inlet (107-1) of the first evaporator (103-1), and having a second refrigeration compartment (101-2) for storing refrigerated goods at a second temperature, said second refrigeration compartment comprising a second evaporator (103-2) with a second controllable expansion valve (105-2) at the refrigerant inlet (107-2) of the second evaporator (103-2), in which refrigeration device a refrigerant outlet (109-1) of the first evaporator (103-1) is connected to the second controllable expansion valve (105-2) at the refrigerant inlet (107-2) of the second evaporator (103-2).

Description

technical field [0001] The present invention relates to a cooling appliance having a plurality of cooling compartments for storing items to be cooled at different temperatures. Background technique [0002] A specific compartment, such as a thawing compartment or a warming compartment set up to 60° C., is provided in the refrigeration appliance. Temperatures above ambient can be achieved with electric heaters. Without heaters, the temperature in the individual storage compartments can only be adjusted to a certain extent. By setting the running time of the compressor, you can get + / -3K temperature difference. [0003] Some special installations, such as wine refrigerators, operate over a wide temperature range. The temperature range includes, for example, 5-22°C and is divided into three temperature zones. These special devices are adjusted by setting the operating time of each evaporator. Other devices have valves in the air passages that can be progressively opened to...
