    Abstract: A three-way heat exchanger for a liquid desiccant air-conditioning system and method of manufacture. The heat exchanger includes a plurality of panel assemblies. Each panel assembly has a frame bordering a given space. The frame includes desiccant inlet and outlet ports and heat transfer fluid inlet and outlet ports. Two plates joined to the frame define a heat transfer fluid channel in the given space. The heat transfer fluid inlet and outlet ports are in fluid communication with the heat transfer fluid channel. Microporous sheets cover the outer surfaces of the plates and define a desiccant channel. The desiccant inlet and outlet ports are in fluid communication with the desiccant channel. The plurality of panel assemblies have a stacked arrangement such that a microporous sheet on one panel assembly faces a microporous sheet on an adjacent panel assembly and defines an airflow channel therebetween.

    Abstract: A compressor may include a shell. A compression mechanism may be disposed within the shell. A drive shaft may be disposed within the shell and drivingly engaged with the compression mechanism. A motor assembly may be drivingly engaged with the drive shaft and may include a rotor and a stator. A plurality of magnets may be disposed within the rotor and may cooperate with the stator to create an electromagnetic field between the rotor and the stator. A counterweight assembly may be secured to the drive shaft and configured to dynamically balance the compression mechanism and secure the plurality of magnets within the rotor.

    Abstract: A refrigeration system includes first and second compressors, a condenser, first and second evaporators, and a valve. The first compressor is fluidly connected to first suction and discharge lines. The second compressor is fluidly connected to second suction and discharge lines. The second suction line is fluidly connected to the first discharge line. The condenser receives refrigerant from the second compressor. The first evaporator receives refrigerant from the condenser and discharges refrigerant to the first suction line. The second evaporator receives refrigerant from the condenser and discharges refrigerant to the second suction line. The valve is disposed between the first evaporator and the first suction line. The first suction line receives refrigerant when the valve is in a first position. The second suction line receives refrigerant when the valve is in a second position. The first compressor is bypassed when the valve is in the second position.

    Abstract: A compressor that includes a shell assembly, a compression mechanism and a conduit. The shell assembly defines a chamber. The compression mechanism is disposed within the chamber of the shell assembly and includes a first scroll member and a second scroll member in meshing engagement with each other. The second scroll member includes an externally located slot and a suction inlet. The conduit includes a first end that defines an inlet opening and a second end that defines an outlet opening. The second end includes a connecting arm that has a first boss extending therefrom. The second end snaps into engagement with the second scroll member such that the first boss is received within the slot of the second scroll member.

    Abstract: A power factor correction (PFC) system includes a desired OFF period module that determines a desired OFF period for a switch of a PFC circuit based on an input voltage to the PFC circuit and an output voltage of the PFC circuit. A switching control module transitions the switch from an ON state to an OFF state when a measured current through an inductor of the PFC circuit is greater than a demanded current through the inductor and maintains the switch in the OFF state for the desired OFF period after the transition from the ON state to the OFF state.

    Abstract: A refrigerated food container system includes a container defining an inner volume and a thermoelectric module arranged in thermal contact with at least one surface of the container. The thermoelectric module includes a first thermoelectric cooling device and a second thermoelectric cooling device in thermal contact with the first thermoelectric cooling device. A control module is configured to provide a first voltage to the first thermoelectric cooling device and provide a second voltage to the second thermoelectric cooling device.
