Proposed is a thermoelement heat exchange module including a body and a thermoelement. The body has a cooling water flow path through which cooling water flows and has an opening which communicates with the cooling water flow path, and has an inlet which is formed at a first side thereof to communicate with the cooling water flow path and through which cooling water is introduced and has an outlet which is formed at a second side thereof to communicate with the cooling water flow path and through which cooling water is discharged. The thermoelement has a first surface thereof coupled to a portion where the opening of the body is formed such that the first surface is exposed on the cooling water flow path. The cooling water flow path has a portion having a relatively small hydraulic diameter in a flow direction of cooling water.

In accordance with the principals of the present invention, an ice machine, tray, and process for producing high-quality, substantially clear ice is provided. A heat exchanger in the ice machine removes energy from liquid, cooling the liquid from room temperature to freezing temperature, then overcomes the heat of fusion to form ice. The tray containing a liquid is received in a freezing/mixing chamber. The tray includes an energy transfer surface in thermal contact with the heat exchanger to define a liquid/ice boundary layer. The tray further includes at least one freezing cavity having geometry defining surfaces to form the geometry of the ice. An egress area is defined in the tray above the geometry defining surfaces. A mixing mechanism is provided in operative communication with the liquid to create a velocity profile at the liquid/ice boundary layer to create a directional freezing process starting from the energy transfer surface of the tray in thermal contact with the heat exchanger and growing through the freezing cavity up to the egress area. The velocity profile at liquid/ice boundary enables impurities to be washed away during the freezing process, deterring impurities from getting entrapped in the ice. Impurities in the liquid are thereby washed away and concentrate in a pool away from the ice, ultimately in the egress area of the tray to be purged. In addition, in embodiments sensors can be provided to provide various functions selected from the group consisting of, for example, determining ice creation status, determining freezing height, varying ice creation, determining tray presence, detecting freezing/mixing chamber door position, determining liquid level, and combinations thereof.

A refrigerator may include a temperature sensor, a thermoelectric device module having a thermoelectric device, and at least one fan and configured to cool a storage compartment, and a controller that controls the output power of the thermoelectric device based on the temperature of the storage compartment, a set temperature, and the outside temperature. The output power of the thermoelectric device may be determined based on whether the temperature of the storage compartment is within a first temperature region including the set temperature, a second temperature region, or a third temperature region. In the first and second temperature regions, the thermoelectric device may operate at different output power and which gradually increases as the outside temperature increases. In the third temperature region, the thermoelectric device may operate at a third output power which exceeds the first output power and is greater than or equal to the second output power.

An apparatus for waste heat recovery is provided. The apparatus includes a base block disposed adjacent to a heat source, a thermoelectric generator including a first end and a second end, the first end being thermally coupled to the base block and configured to receive heat from the heat source, and a thermoelectric cooler including a third end and a fourth end, the third end being thermally coupled to the second end. The thermoelectric cooler is configured to receive an electric current, which causes the third end to cool and the fourth end to heat such that the third end conducts heat from the second end. Related apparatus, systems, techniques, and articles are also described.

The present invention introduces a temperature calibrator arrangement, which comprises inner and outer Peltier elements as heating and cooling elements for the calibrator block. The arrangement comprises a first and second variable current or voltage source, and, in an embodiment, a first and second mechanical relay for switching polarities of the Peltier elements.
