  • Patent number: 11906188
    Abstract: An energy efficient heat pump for a heating, ventilation, and air conditioning (HVAC) system includes a compressor system configured to direct a working fluid flow along a working fluid circuit of the energy efficient heat pump. The compressor system includes a first compressor configured to direct the working fluid flow in a first direction along the working fluid circuit and a second compressor configured to direct the working fluid flow in a second direction along the working fluid circuit, opposite the first direction. The energy efficient heat pump also includes a controller communicatively coupled to the first compressor and the second compressor, where the controller is configured to operate the first compressor and suspend operation of the second compressor in a cooling mode of the energy efficient heat pump and to operate the second compressor and suspend operation of the first compressor in a heating mode of the energy efficient heat pump.

  • Publication number: 20230332553
    Abstract: An internal combustion engine is operated at fuel-rich conditions by adjusting one or more operating parameters such as, for example, a throttle, an ignition timing, a load coupled to the engine, a fuel pressure, power to a supercharger, and power to a preheater to maintain a specified engine speed and a temperature of an exhaust gas. Operating the engine under these conditions allows the engine to function as a reformer producing a synthesis gas comprising hydrogen and carbon monoxide.

  • Patent number: 11428461
    Abstract: An apparatus includes a high side heat exchanger, a load, a compressor, a belt, a first bin, a second bin, and a controller. The high side heat exchanger removes heat from a refrigerant. The load uses the refrigerant to cool an enclosed space. The compressor compresses the refrigerant. The first and second bins are coupled to the belt and positioned within the enclosed space. The controller receives a first message, determines that the first bin should be selected, and cycles the belt to move the first bin to a retrieval location within the enclosed space. The controller also receives a second message, determines that the second bin should be selected, and cycles the belt to move the second bin to the retrieval location.
