A supercooling refrigerator (1000) including: a refrigerator body (100); a door (200) for opening and closing one side of the refrigerator body (100); an accommodating portion (400) provided inside the refrigerator body (100) and seated with an object (M) to be stored; a cooling duct (600) including a fan for taking in air in the refrigerator body (100) and discharging the air, and an evaporator (630) for cooling the air discharged from the fan; and a cool air supply duct (700) formed with a cool air discharge port (710) through which the air cooled through the cooling duct (600) is discharged into the refrigerator body (100), the fan being a cross flow fan (620) including a plurality of discs (622), and a plurality of blades (623) disposed between the discs (622) along outer circumferential surfaces of the discs (622).

A portable cooler container is provided. The temperature control system cools a chamber of the container to transport temperature sensitive contents via the container. An electronic display screen on one of the lid and the container body selectively displays an electronic shipping label for the portable cooler container.

Disclosed is a refrigeration unit having an accumulator, a refrigeration system and a method for controlling a refrigeration unit having an accumulator, wherein the refrigeration unit has a refrigeration chamber for receiving and storing goods to be refrigerated, an accumulator having an accumulator holder in which a storage medium is accommodated, a heat exchanger, a controller and a coolant line arrangement which can be connected to a coolant supply network via connections. The coolant line arrangement is guided through the accumulator holder, and the heat exchanger is thermally coupled to the storage medium accommodated in the accumulator holder. A coolant control device is arranged in the flow pipe of the coolant arrangement, wherein the storage medium accommodated in the accumulator holder is cooled via a coolant in the coolant line arrangement, and the heat exchanger is cooled via the storage medium.

This present disclosure provides a vessel assembly for use in temperature sensitive shipping that can maintain a payload temperature across a range of temperatures. The vessel assembly of the present disclosure comprises a vessel having a single chamber, in which a plurality of PCMs are in contact, but immiscible, with each other. The present disclosure reduces the overall packaging materials used in a shipper box and prevents the “wrong” mixture of PCM-containing vessels from being used.

In one aspect, a portable-smart refrigerator includes a lid assembly comprising a lid coupled with a lid bottom cover for fastening the lid assembly to an internal upper portion of a PCM chamber assembly. The portable-smart refrigerator includes a grill assembly comprising a top base, a pump bracket, a middle base, a bottom base. The top based hold the pump bracket. the top base is coupled with the middle base. The middle base is coupled with the bottom base. The portable-smart refrigerator includes a cooling-coil assembly comprising a feeding tube, a top elbow, a bottom tube, a cooling coil. The top elbow is installed between two lengths of tubing/pipe to enable a change of direction and couples the feeding tube with the cooling coil. The cooling coil is coupled with the bottom tube. The portable-smart refrigerator includes the phase change material (PCM) chamber assembly that holds the cooling coil. The PCM chamber is placed within an outer cylinder. A bottom portion of the PCM chamber assembly is coupled with the grill assembly. A sleeve assembly forming a portion of the outer cylinder.

A portable cooler container is provided. The temperature control system cools a chamber of the container to transport temperature sensitive contents via the container. An electronic display screen on one of the lid and the container body selectively displays an electronic shipping label for the portable cooler container.

A method of manufacturing a dew formation preventing member having a super water repellent surface of the present invention comprises the steps of: mixing a particular paint and polytetrafluorethylene at a predetermined ratio; particulate painting the mixed paint on a substrate surface; and heat treating the particulate painted substrate. A method of manufacturing a dew formation preventing member having a super water repellent surface according to another aspect of the present invention comprises the steps of: immersing a substrate in an electro deposition paint, and applying a direct current to conduct electro deposition painting; heat treating the substrate that has undergone the electro deposition painting; and plasma treating the surface of the substrate that has undergone the electro deposition painting.

A method and system for transporting and/or storing temperature-sensitive materials. In one embodiment, the system may be a hybrid system that includes an active temperature-control system and a passive temperature-control system. The active temperature-control system may be, for example, a portable refrigerator that includes an internal chamber for maintaining contents within a desired temperature range. The passive temperature-control system, which includes at least one phase-change material (PCM) member and space for receiving one or more temperature-sensitive materials, may be removably positioned entirely within the internal chamber of the active temperature-control system. When temperature-sensitive materials are loaded into the passive temperature-control system and the passive temperature-control system is loaded into the active temperature-control system, the active temperature-control system keeps the temperature-sensitive materials within a desired temperature range and charges the PCM members for when the passive temperature-control system is thereafter removed from the active temperature-control system.

A portable container has a payload chamber for holding goods and a lid operable to access the payload chamber. The portable container also has an electronic system with one or more power storage devices, circuitry that wirelessly communicates via a cell radio with a cloud-based data storage system or a remote electronic device, and an electronic display screen. The electronic system also has a button or a touch screen configured to be actuated by a user to a) automatically switch sender and recipient information on the electronic display screen to facilitate return of the portable container to the sender or b) automatically contact a parcel carrier to alert the parcel carrier that the portable container is ready for pickup.
