    Abstract: A wearable air purification system having a wearable support configured to be supported on a user's head. The wearable support is attached to an air delivery mask which delivers a flow of air to an air delivery region. A motor for driving the flow of air to the air delivery region is mounted on the wearable support, or on the air delivery mask, and an air filter for purifying the flow of air is mounted on the wearable support, or on the air delivery mask. Each end of the air delivery mask is moveably connected to the wearable support so that the wearable support is able move with respect to the air delivery mask from a deployed position to a stowed position. The volume envelope of the wearable air purification system is larger in the deployed position than in the stowed position.

    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: There is provided a head wearable air purifier comprising a first speaker assembly and a second speaker assembly, wherein the first speaker assembly comprises a filter assembly, an impeller for creating an airflow through the filter assembly, a motor arranged to drive the impeller, and an air outlet downstream from the filter assembly for emitting the filtered airflow from the speaker assembly. The head wearable air purifier further comprise a nozzle arranged to receive the filtered airflow from the first speaker assembly, the nozzle comprising an air outlet arranged to emit the received filtered airflow from the head wearable air purifier. The filter assembly is provided upstream of the impeller and comprises one or more generally frusto-conical filter elements.

    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.
