  • Patent number: 10858233
    Abstract: A primary beverage cooling circuit for refrigerating a fluid used in a secondary beverage cooling circuit that cools beverage in a beverage conduit by pumping the fluid through a heat exchange conduit adjacent the beverage conduit to transfer heat therebetween, the primary beverage cooling circuit comprising: a refrigerant circuit containing a refrigerant circulating through: a heat exchanger in heat transfer communication with the fluid to cool the fluid; a variable displacement compressor for circulating the refrigerant through the refrigerant circuit; a cooling device for cooling the refrigerant; and a valve for controlling the volume of fluid into the heat exchanger; the primary beverage cooling circuit further comprising a controller for controlling the operation of the compressor and/or the cooling device and/or the valve based on one or more measurements from temperature and/or pressure sensors in the refrigerant circuit to thereby operate the system on an efficient basis.

  • Patent number: 10238132
    Abstract: A primary beverage cooling circuit for refrigerating a fluid used in a secondary beverage cooling circuit cools beverage in a beverage conduit by pumping the fluid through a heat exchange conduit adjacent the beverage conduit to transfer heat therebetween. The primary beverage cooling circuit includes a refrigerant circuit containing a refrigerant circulating through a heat exchanger in heat transfer communication with the fluid to cool the fluid, a variable displacement compressor for circulating the refrigerant through the refrigerant circuit, a cooling device for cooling the refrigerant, and a valve for controlling the volume of fluid into the heat exchanger. The primary beverage cooling circuit further includes a controller for controlling the operation of the compressor and/or the cooling device and/or the valve based on one or more measurements from temperature and/or pressure sensors in the refrigerant circuit to maintain a temperature of the fluid and/or refrigerant about a set-point temperature.

  • Publication number: 20070175236
    Abstract: Pallet version of the portable refrigeration container including a palletised thermally insulated base (20) including seal mechanism, forklift fork receiving cavities (21) allowing ready transportability. A dismantlable wail assembly (35) comprising hinged vacuum insulated panels (35) are able to be mounted on the palletised thermally insulated base (20) and engaging with the perimeter channel (23) forming the base sealing mechanism. The thermally insulated hinge type collapsible concertina configuration of side panels (35) have latch mechanism for holding panels in rectangular configuration defining a container volume therein. A thermally insulated lid (40) covers the top of the container volume and includes a seal mechanism for engaging with the wall assembly. The portable refrigeration container includes an integral cooling system, for cooling the container volume, incorporated in one or more of the base, sides or lid.
