The invention features a refrigerator cabinet door frame. The frame includes a thermally conductive outer frame, a thermally insulating inner frame member, and a sealing plate. The outer frame member includes a forward end having an outer surface that is disposed outside of a refrigerated cabinet with the frame mounted, and a rearward end defining a joint. The inner frame member includes a first end retained in the joint, and a second end. The sealing plate includes a first edge coupled to the outer frame member at the rearward end, forward of the joint, a second edge supported by the second end of the inner frame member, and a thermally conductive sealing surface. The first edge of the sealing plate is coupled to the outer frame member such that the sealing surface and the outer surface of the outer frame member together form a continuous heat transfer path.

A refrigerator includes a cabinet, a door configured to open/close the cabinet, an outer plate defining a front surface of the door and having an opening formed therein to pass through the door, a door liner defining a rear surface of the door, lighting members configured to illuminate storage spaces of the door and the cabinet, a transparent panel assembly mounted to shield the opening and allowing the storage spaces to be selectively seen according to an ON/OFF state of the lighting members, an insulator filled between the outer plate and the door liner, and a blocking part arranged inside the door along a periphery of the transparent panel assembly and detachably coupled to a peripheral surface of the transparent panel assembly to fix the transparent panel assembly.

In one general aspect, the subject matter described in this specification can be embodied in a display case door that includes an insulated panel assembly that is transparent to visible light. The door further includes a door frame extending about and secured to a peripheral edge of the insulated panel assembly, an electronic display overlaying the insulated panel assembly, and at least one display retainer secured to the door frame and having a coupling end that mates with the electronic display to releasably secure the display to the door frame.

A refrigeration system includes a primary refrigeration circuit configured to circulate a CO.sub.2 primary refrigerant and a secondary refrigeration circuit separate from the primary refrigeration circuit. The primary refrigeration circuit includes a compressor assembly, a condenser assembly, a receiver, and one or more refrigeration loads having an evaporator assembly. The secondary refrigeration circuit includes a thermal storage unit and a heat exchanger. The thermal storage unit contains a phase change material. The secondary refrigeration circuit is in thermal communication with the primary refrigeration circuit through the heat exchanger. The primary refrigerant includes a critical temperature. The primary refrigeration circuit is configured for subcritical operation. The primary refrigeration circuit and the secondary refrigeration circuit are configured such that the phase change material provides cooling to the primary refrigerant during a first operating condition. The phase change material is configured to maintain subcritical operation of the primary refrigeration circuit during the first operating condition when the primary refrigerant is above the critical temperature.

In one general aspect, the subject matter described in this specification can be embodied in a display case door that includes an insulated panel assembly, a door frame, and an electronic display mounted to the door. The door frame extends about and is secured to a peripheral edge of the insulated panel assembly. The electronic display overlays the insulated panel assembly. A mounting bezel is secured to the door frame and has a coupling end that extends over an edge of the electronic display securing the electronic display to the door frame. A cover bezel is coupled to a front surface of the door frame, where the cover bezel is sized to overlay the front surface of the door frame and the coupling end of the mounting bezel.

The present disclosure relates to a refrigerator and a transparent panel assembly for a refrigerator. The transparent panel assembly for a refrigerator comprises: a front panel defining at least a part of a front appearance of a refrigerator door and made of a glass material; a rear panel defining at least a part of a rear appearance of the refrigerator door and made of a transparent material; and an intermediate member connected between the front panel and the rear panel and made of a transparent plastic member, wherein the intermediate member comprises: an edge portion having both ends connected to a screening area formed at peripheries of the front panel and the rear panel; and a partition portion formed to cross an inner surface of the edge portion to partition a gap between the front panel and the rear panel to thereby form a sealed insulation layer.

A display system for a refrigerated display case includes a door assembly which permits access to a product storage compartment. The door assembly includes an electronic display layer positioned within an enclosure defined by a front cover layer, a rear cover layer, and a spacer extending about a perimeter of interior surfaces of the front and rear cover layers. The front cover layer permits viewing of images displayed at the electronic display layer through the front cover layer. Electronic equipment for operating the electronic display layer is located outside of the enclosure.

A door for a home appliance, a home appliance, and a method for manufacturing the same, are disclosed. The door for a home appliance comprises a panel assembly; and a frame assembly defining a predetermined space having an opening connected with an edge of the panel assembly, and making a foaming space for receiving a thermal insulator by means of the predetermined space of the frame assembly and the edge of the panel assembly, wherein a foaming injection hole through which the thermal insulator is injected is provided on at least one of ends of an upper surface, a lower surface, a left side and a right side of the frame assembly.

An outdoor unit is connected to a refrigerator and has two compressors that are connected in series, and a control method thereof. The outdoor unit according to an embodiment of the present invention includes a low pressure side compressor for compressing a refrigerant; a high pressure side compressor for compressing the refrigerant compressed by the low pressure side compressor; an outdoor heat exchanger for condensing the refrigerant compressed by the high pressure side compressor; a heat recovery unit for cooling the refrigerant condensed in the outdoor heat exchanger by exchanging heat with the refrigerant evaporated in the air conditioner; and a supercooler for expanding a part of the refrigerant cooled in the heat recovery unit to cool another part of the refrigerant cooled in the heat recovery unit, so that the discharge temperature of the low pressure side compressor and/or the high pressure side compressor can be reduced.

A display control method according to an aspect of the present disclosure includes: judging whether a malfunction has occurred in a cooling system; when it is judged in the judging that a malfunction has occurred in the cooling system, identifying a type of the malfunction based on at least one item of equipment information among items of equipment information obtained from the cooling system and including at least one of measurement information or setting information; determining a display mode for the at least one item of equipment information based on at least one of the type of the malfunction or a factor in identifying the type of the malfunction; and causing a display device to display (i) the at least one item of equipment information in the display mode determined in the determining and (ii) type information indicating the type of the malfunction.
