Aspects herein are directed to an apparel thermo-regulatory system that actively heats or cools a wearer. The apparel thermo-regulatory system comprises an apparel item, a dimensionally stable frame comprising at least one aperture that is affixed to an outer-facing surface of the apparel item at a predetermined location, an absorbent material applied to an exposed face of the dimensionally stable frame, and at least one thermoelectric module that is releasably positioned within the aperture of the dimensionally stable frame.

A refrigerator according to the present disclosure includes at least one storage chamber and uses an electromagnetic wave to heat a stored object inside the storage chamber. A first electromagnetic wave shield is provided on a door of the storage chamber, and a second electromagnetic wave shield is provided on a housing part of the refrigerator that is in contact with the door while the door is closed. This makes it possible to provide a structure capable of exhibiting a function as an electromagnetic wave shield even for a refrigerator door in which wiring to a grounding part is difficult.

Provided is a refrigerator. The refrigerator is characterized by enabling at least a part of a refrigerator door to be selectively transparent by a user's operation, such that the user sees through an inside of the refrigerator while the refrigerator door is closed.

A sensor-equipped RF tag is attached to a cooling box accommodating a cooling agent, and detects a temperature inside the cooling box, and a temperature and a position of the cooling agent. The sensor-equipped RF tag sends the detected temperature inside the cooling box, and the temperature and the position of the cooling agent to a server directly or via a taximeter. The server orders the cooling agent from a center terminal installed in a freezing center around a position of a taxi vehicle based on a detection result of the sensor-equipped RF tag.

Devices, systems, and methods are provided for heating and cooling substances, such as food and beverages. A portable device may have an exterior surface and an interior surface, with one or more heating elements positioned at least partially between the exterior surface and the interior surface, and with one or more cooling elements positioned at least partially between the exterior surface and the interior surface. The portable device may include one or more power sources operatively connected to the one or more heating elements and the one or more cooling element, and may include at least one processor that controls, based on the one or more power sources, activation of one of the one or more heating elements or the one or more cooling elements at a time.

A refrigeration device, a refrigerator, and a control method therefor, a food processing method and a control device. The refrigeration device includes a compressor, a condenser, a throttling device and an evaporator, and the compressor, the condenser, the throttling device and the evaporator are sequentially connected to form a refrigerant circulation loop; a connecting pipeline between an exhaust port of the compressor and a refrigerant inlet of the throttling device in the refrigerant circulation loop is a first connecting pipeline; and the condenser is arranged on the first connecting pipeline. The refrigeration device further includes an auxiliary heat exchange branch, and the auxiliary heat exchange branch includes a condensing heater for heating a heating region, and is arranged on the first connecting pipeline in parallel; and a first valve device is further arranged on the auxiliary heat exchange branch.

Temperature-controllable container with vacuum insulation elements and with an interior space, which container comprises a wall with an opening for objects to be placed into the interior space, and a door element closing the opening, wherein transport elements are arranged on an outer surface of the container, which transport elements are designed to enable lifting by means of a transport vehicle, and wherein the container further comprises a temperature control unit which is designed so as to bring the interior space to a predetermined temperature T, wherein the temperature control unit comprises a heating/cooling unit operated via a solar energy device or a heating/cooling unit operated via a power supply network, and wherein a receptacle means for melt-storage elements or sample bodies is arranged in the interior space, which receptacle means is designed so as to position at least two melt-storage elements or sample bodies at a distance from each other.
