    Abstract: A refrigeration system is described having a circuit around which a refrigerant circulates. The circuit includes a compressor, a metering device, a first heat exchanger for exchanging heat between the refrigerant and a medium, and a second heat exchanger for exchanging heat between the refrigerant and a thermal store. The refrigeration system is operable in a first mode and a second mode. In the first mode, the metering device has a first restriction such that the medium is cooled at the first heat exchanger and the thermal store is heated at the second heat exchanger. In the second mode, the metering device has a second, less restrictive restriction or is bypassed such that the medium is heated at the first heat exchanger and the thermal store is cooled at the second heat exchanger.

    Abstract: Provided is refrigeration system having a circuit around which a refrigerant is circulatable. The circuit includes a compressor, a heat exchanger for exchanging heat between the refrigerant and a medium, and an accumulator for accommodating liquid refrigerant. The accumulator is fluidically coupled in a suction line between the heat exchanger and the compressor. The refrigeration system is operable in a cooling mode such that the medium is cooled at the heat exchanger, and the accumulator is oversized at a maximum cooling capacity of the refrigeration system in the cooling mode.

    Abstract: A compressor is provided for use in domestic appliances. The compressor includes: an impeller including an inlet, an outlet, a hub defining a rotational axis of the impeller, a plurality of impeller blades that extend from the hub, and a shroud that at least partially surrounds the impeller blades; a housing that at least partially surrounds the shroud and that is coaxially arranged with respect to the rotational axis of the impeller to allow the impeller to rotate within the housing; a leakage flow path defined between the shroud and the housing leading from a leakage flow path inlet to a reinjection port, and a labyrinth seal arrangement provided in the leakage flow path. The labyrinth seal arrangement includes one or more shroud rings interdigitated with one or more housing rings so as to form a tortuous flow path for fluid flowing through the leakage flow path.
