The present disclosure relates to the field of household appliances technologies, and discloses a refrigerator with a separate ice-making system which comprises a refrigerating compartment and an ice-making chamber disposed inside the refrigerating compartment, wherein an ice maker is arranged in the ice-making chamber, the ice-making chamber is supplied with cold air by an ice-making refrigeration system including an ice-making evaporator, an ice-making air supply duct, an ice-making fan and an ice-making air return duct, the ice-making air supply duct and the ice-making air return duct are located front to back, the ice-making evaporator is disposed in the refrigerating compartment and located outside the ice-making chamber, and the ice-making evaporator is communicated with the ice maker through the ice-making air supply duct and the ice-making air return duct to form a refrigerating cycle loop.

A refrigerator and method utilize a door-mounted icemaking system including an icemaking mold, an ice storage bin and a cold wall evaporator disposed proximate the ice storage bin along an interior wall of the door to provide cooling proximate the ice storage bin. In some instances, the cold wall evaporator may be in addition to an icemaking evaporator that provides direct cooling of the icemaking mold, and furthermore, in some instances, the cold wall and icemaking evaporators may be separately controllable to optimize cooling within the door-mounted icemaking system. In addition, in some instances, a hot wall condenser may be used in a door-mounted icemaking system to dissipate heat generated by a refrigeration circuit through an exterior wall of a door. Further, in some instances a reversible refrigeration circuit may be used in connection with an icemaking evaporator to assist in ejecting ice from an icemaking mold.

An auxiliary thermosiphon has an auxiliary refrigerant conduit with an auxiliary evaporation segment in thermally conductive connection to an interior wall of the freezer. The auxiliary refrigerant conduit contains an auxiliary refrigerant that is isolated from the primary refrigerant of the primary cooling apparatus. The auxiliary refrigerant conduit also extends upward to an auxiliary condensation segment of the auxiliary refrigerant conduit at an elevation above the auxiliary evaporation segment. A thermal bridge is in physical thermal contact with the auxiliary condensation segment and in physical thermal contact with a portion of a primary evaporation segment of the primary refrigeration apparatus. Heat is transported through the thermal bridge from the auxiliary thermosiphon to the primary refrigerant conduit and consequently to the primary refrigeration apparatus for removal from the freezer.

A refrigerator comprises: a cabinet having a refrigerating chamber; a refrigerating chamber evaporator provided to correspond to the refrigerating chamber, and configured to generate cool air by a driving of a compressor; an evaporator temperature sensor mounted to the refrigerating chamber evaporator, and configured to sense a temperature; a blower fan configured to supply cool air generated from the refrigerating chamber evaporator to the refrigerating chamber; and a controller configured to determine whether to stop the blower fan or not, based on a temperature of the refrigerating chamber evaporator sensed by the evaporator temperature sensor when the compressor is stopped.

A refrigerator includes a cabinet configured to have an inner case in which a storage space is formed, and a partition member configured to partition the storage space into a first space and a second space, in which the inner case includes a first body facing the first space, and a second body facing the second space, and at least one hole is formed between the first body and the second body.

A refrigerator includes a cabinet configured to form a first storage chamber and a second storage chamber, a first evaporator configured to cool the first storage chamber, a first fan configured to circulate air in the first storage chamber to the first evaporator and the first storage chamber, a second evaporator configured to cool the second storage chamber, a compressor configured to be connected to the first evaporator and the second evaporator, a second fan configured to circulate air in the second storage chamber to the second evaporator and the second storage chamber; a refrigerant valve configured to guide refrigerant to the first evaporator or the second evaporator, and a controller configured to perform a plurality of modes sequentially to defrost the second evaporator.

A refrigerator includes a discharge body configured to be formed with a discharge port and a suction port, a flow path body configured to be disposed in the discharge body and forms a discharge flow path for guiding air to the discharge port, an air guide configured to be formed with a scroll and an opening that guides air to the discharge flow path and an outlet spaced apart from the opening, and a fan provided inside the air guide.

A refrigerating device used to reduce a temperature of drinks is provided and a higher refrigerating efficiency can be obtained through a control method and a control system thereof. The refrigerating device includes a pre-refrigeration unit used to pre-refrigerate a raw material; a main-refrigeration unit in communication with the pre-refrigeration unit and used to accommodate the pre-refrigerated raw material and refrigerate the raw material further; a dispenser in communication with the main-refrigeration unit and used to dispense the frozen drink in the main-refrigeration unit; and a refrigeration system providing a refrigerating capacity to the pre-refrigeration unit and the main-refrigeration unit.

The present invention provides a ternary natural refrigerant mixture containing R-600a (isobutane), R-600 (isobutane), and R-290 (propane) that can be used in single or dual evaporator refrigeration systems to provide for more energy efficient cooling than a single refrigerant such as R-134a without having to change the compressor design, which can add to manufacturing costs. For example, the ternary natural refrigerant mixture can be used in a refrigeration system that uses dual evaporators to provide more efficient cooling. The refrigeration system can be used in, e.g., a refrigerator having a fresh food compartment and a frozen food compartment to provide separate cooling to each compartment simultaneously.
