Abstract (en)
[origin: ES470936A1] A refrigerator comprising a freezing compartment and a refrigerating compartment which refrigerator is provided with a primary refrigerating system containing a refrigerant with a primary evaporator disposed in the freezing compartment, and a secondary refrigerating system which also contains a refrigerant with a secondary evaporator disposed in the refrigerating compartment, and a secondary condensor which is in heat-exchanging contact with the primary evaporator, which condensor has a condensation wall on whose surface the refrigerant condenses during operation, means being provided for varying the available condensation wall area, so as to control the temperature of the secondary evaporator. Preferably, the secondary condensor is provided with a reservoir containing a control gas, which during operation constitutes an interface with the refrigerant vapor at the location of the condensation wall, the interface being movable along the condensation wall with the aid of a reversible control gas getter, which can be heated and which is located in the reservoir, which getter enables the amount of free control gas to be varied. The reversible control-gas getter can be heated by means of an electric heating element which is included in an electrical control circuit.
