摘要:
The present invention relates to a method for operating a vehicle air-conditioning system (3) having a refrigeration circuit (13), in which a refrigerant circulates, and having an evaporator (14) for cooling an air flow (12), and to a thermoelectric heating device (18) for heating the air flow (12), the heating device (18) and the evaporator (14) being situated in a duct (11) leading into the vehicle interior (2). The refrigerant circuit (13) is activated in order to cool the vehicle interior (2). In order to improve comfort conditions by a perceptibly rapid response of the interior cooling system, the heating device (18) is operated as a cooler during a start-up phase of the refrigerant circuit (13), such that the heating device (18) extracts heat from the air flow (12).
摘要:
The present disclosure provides a thermoelectric device comprising a panel comprising an electrically and thermally insulating material, and a thermoelectric string comprising a plurality of thermoelectric elements mounted on a strain relief element within the panel. The thermoelectric elements may comprise an n-type thermoelectric element and a p-type thermoelectric element electrically coupled to one another in series. The thermoelectric string may be (i) compacted in cross section inside the panel and (ii) expanded in cross section outside the panel. The strain relief element may permit the thermoelectric string to be movable in proximity to the strain relief element.
摘要:
An ice maker, including sensors (444) to measure usage parameters and transmit the same to a controller (440). The controller is operably connected to a plurality of ice forming systems, and directs the systems to operate in a high energy mode or a low energy mode, based on the usage parameter. The usage parameters may include an ice level (98), a change in the ice level over time, the amount of time that a dispenser is actuated, the time of day, or historical usage patterns. The ice forming systems (52) may include one or more of a thermoelectric device coupled to a bottom surface of an ice forming plate, a forced air system to circulate cold air, a forced air system to circulate warm air, and a temperature control system to maintain a temperature gradient between a first chamber above the ice forming plate and a second chamber below the ice forming plate.
摘要:
A refrigerator (10) includes a refrigerator cabinet (12), an ice maker (32) disposed within the refrigerator cabinet, an ice mold (40) in the ice maker, and a thermoelectric device (46) positioned below the ice mold and configured to provide cooling liquid along a bottom side of the ice mold during freezing of water to make ice. The ice maker is further configured to warm the bottom side of the ice mold to facilitate harvesting of the ice. The ice maker may be disposed within a refrigeration compartment and may be configured to make clear ice. The ice mold may be fixed in place during the harvesting of the ice. The ice maker may be further configured to warm the bottom side of the ice mold to facilitate harvesting of the ice by providing warming liquid along the bottom side of the ice mold.
摘要:
Systems and apparatus for heating or cooling food to an appropriate temperature for service using a standard food service container, such as a chafing dish or food cart. A thermally conductive plate has a plurality of Peltier chips attached thereto to drive a temperature difference. The Peltier chips are in thermally conductive contact with a heat exchanger. A heat transfer liquid circulates through tubing in the heat exchanger and a separate radiator, perpetuating the temperature difference at the plate. The heat exchanger and radiator may be spaced apart by a gap. One or more fans may be placed to encourage airflow through the radiator. A coolant reservoir and pump may be included.
