Abstract: A refrigerator includes a main body that has a storage chamber and a drying chamber; a thermoelectric module that includes a heat absorber and a heat dissipater; a cooling fan that circulates air in the storage chamber to the heat absorber and the storage chamber; a heat-dissipating fan that blows air to the heat dissipater; an air guide that has a passage for guiding air heated by the heat dissipater to the drying chamber; a heater that is disposed in the passage; and a damper that controls a flow of air in the passage between the heat-dissipating fan and the heater. Heat of the heat dissipater transfers to the drying chamber through the passage of the air guide and the damper, thereby being able to dry an object to be dried.

Abstract: The system for treating a gas deriving from the evaporation of a cryogenic liquid and supplying pressurized gas to a gas engine according to the invention comprises, on the one hand, from upstream to downstream, a reliquefaction unit (10) with compression means (11, 12, 13), a first heat exchanger (17) and expansion means (30), and, on the other hand, a pressurized gas supply line comprising, from upstream to downstream, a pump (48) for pressurizing the liquid and high-pressure vaporization means (61). The pressurized gas supply line has, upstream of the vaporization means (61), a bypass (57) for supplying a second heat exchanger (60) between, on the one hand, pressurized liquid of the supply line (56) and, on the other hand, a line (22) of the reliquefaction unit (10) downstream of the first exchanger and upstream of the expansion means (30).

Abstract: A portable refrigeration container is usable for cooling a bottle of drinkable fluid. It includes a tubular body, a vortex tube, an electronic programmable controller, a tank of compressed air, a battery, a Peltier device, a heat exchanger, and a removable electrical charging station. Optionally, the portable refrigeration container further includes a compressor, a dynamo, and a bracket for attachment to a bicycle frame. The optional compressor and dynamo that electrically recharges the battery, may share a single shaft that is rotatably connected to turn with a bicycle wheel.

Abstract: An air conditioner is provided, which is capable of accurately determining appropriateness of a refrigerant amount in a refrigerating cycle. A control apparatus is configured to: stop a cooling operation; set an expansion valve to a fully-closed state and, at the same time, switch the selector valve to change the direction, in which a refrigerant flows, to an opposite direction; operate a compressor to perform a refrigerant recovery operation, in which a refrigerant contained in an outdoor heat exchanger is recovered by an indoor heat exchanger; and determine the appropriateness of a refrigerant amount in a refrigerating cycle, based on at least one of a time required for recovering the refrigerant, a pressure change in a refrigerant suctioned by the compressor, and temperature of the refrigerant discharged from the compressor during the refrigerant recovery operation.

Abstract: An automated refrigerant recharging system determines whether a cooling load parameter of a direct expansion (DX) cooling system that cools information technology (IT) modules of an information handling system (IHS) has reached a defined recharging threshold that results in a response of the pressure value for measurement by the pressure transducer. In response to the cooling load parameter being equal to or greater than the defined recharging threshold, a controller determines whether a pressure value of the refrigerant of the DX cooling system is less than a defined target pressure value corresponding to the defined recharging threshold. In response to determining that the pressure value of the refrigerant of the DX cooling system is less than the defined target pressure value, the controller autonomously opens a control valve to transfer refrigerant to the DX cooling system.

Abstract: A heat source integrated air conditioner, which includes a freezer, a cooling tower, and a device for heating and is integrated up to heat source supply equipment to be capable of supplying cooling and heating as well as dehumidification, humidification, and ventilation is provided. The heat source integrated air conditioner is formed on an upper side of one frame and installed outside or on a rooftop of a building, thereby reducing time and cost for manufacturing, installation and maintenance, increasing utilization of a space inside a building, reducing heat loss and appliance costs by minimizing piping distance, and creating a pleasant indoor environment, and also enhancing utilization of a space inside the building and maximizing energy saving during operation of cooling/heating.
