Abstract: Provided is a refrigeration system including a thermal store and a circuit around which a refrigerant circulates. The circuit includes a compressor and a heat exchanger. The heat exchanger exchanges heat between the refrigerant and the thermal store, and the thermal store surrounds at least part of the compressor to absorb noise generated by the compressor.

Abstract: A fan assembly is described comprising a refrigeration system, an airflow generator and a condensation collector. The refrigeration system comprises a first heat exchanger and a second heat exchanger. The airflow generator is for generating an airflow over the second heat exchanger, and the condensation collector is for collecting condensate that forms on the second heat exchanger.

Abstract: A fan assembly is described comprising a refrigeration system and an airflow generator. The refrigeration system comprises a first heat exchanger, a second heat exchanger, and a compressor. The airflow generator is for generating an airflow over the second heat exchanger. The first heat exchanger surrounds a major portion of the compressor, and the second heat exchanger is located above the first 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 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: There is provided a valve for a reversible heat pump system, including six ports and three flow paths for a refrigerant, the three flow paths being selectable between different pairs of the six ports, wherein: two of the three flow paths are non-restrictive flow paths; and one of the three flow paths is a restrictive flow path. There is also provided a reversible heat pump system, including: the valve; a compressor; a process heat exchanger having input and output sides through which refrigerant is supplied and discharged respectively; and a rejection heat exchanger having input and output sides through which the refrigerant is supplied and discharged respectively, wherein the valve interconnects the compressor, the process heat exchanger and the rejection heat exchanger such that a refrigeration cycle can be established.
