  • Publication number: 20250137711
    Abstract: A refrigeration apparatus (10) has one or more chambers (12?, 12?) in which items to be cooled can be located. A compressor (20 driven by an electric motor (22) compresses vaporised refrigerant as part of a refrigeration cycle. The refrigeration apparatus (10) has an ambient temperature sensor (34) for measuring ambient temperature and at least one inner temperature sensor (36, 38) for measuring a temperature of the interior of the refrigeration apparatus (10). A controller (40) receives outputs from temperature sensors (34, 36, 38). The controller (40) obtains measures of a motor current of the electric motor (22) at time intervals which are based on the ambient temperature and the inner temperature. Based on the measures of the motor current at the time intervals, the controller (40) at least one of (ii) controls operation of the electric motor (22) and (ii) initiates defrost procedure for the refrigeration apparatus (10).

  • Publication number: 20230025112
    Abstract: The present disclosure relates to an apparatus (100) for magnetic cooling. The apparatus (100) includes a first region (110) for magnetizing two or more magnetic elements (120-1, 120-2, 120-3) of different sizes; two or more second regions (130-1, 130-2, 130-3); and two or more channels (140-1, 140-2, 140-3) having different sizes, wherein each channel of the two or more channels (140-1, 140-2, 140-3) connects the first region (110) and a respective second region of the two or more second regions (130-1, 130-2, 130-3), and wherein the two or more channels (140-1, 140-2, 140-3) are configured for a transport of the two or more magnetic elements (120-1, 120-2, 120-3) from the first region (110) to the two or more second regions (130-1, 130-2, 130-3).

  • Patent number: 11480383
    Abstract: Device for detecting formation of water ice on a substrate has a first permanent magnet and a second permanent magnet. The magnets are spaced apart and arranged with a north pole of one magnet opposed to a south pole of the other magnet. A container contains a body of water within the space between the permanent magnets. At least one of the magnets is movable in the container. A heat conductor arrangement conducts heat between the substrate and the body of water the container. As heat is conducted from the body of water in the container to the substrate and the temperature of the body of water decreases below the temperature at which the density of water is a maximum, the volume of the body of water increases which drives the first and second permanent magnets apart from each other.
