    Abstract: Climate control systems and methods of operating them are provided that circulate a working fluid including a high glide refrigerant blend having first and second refrigerants with a difference in boiling points ≥ about 25°F at atmospheric pressure. The system includes a gas-liquid separation vessel that generates a vapor stream and a liquid stream. A compressor receives the vapor stream and generates a pressurized vapor stream. A liquid pump receives the liquid stream and generates a pressurized liquid stream. A condenser is disposed downstream of the compressor and liquid pump and receives and cools the pressurized mixed vapor and liquid stream. An evaporator receives and at least partially vaporizes the multiphase working fluid and directs it to the gas-liquid separating vessel. An expansion device between the condenser and the evaporator processes the multiphase working fluid stream. Lastly, a fluid conduit for circulating the working fluid through the components is provided.

    Abstract: A compressor includes a compression mechanism, a motor, a drive shaft, and a motor cooler. The compressor is configured to compress a working fluid. The motor dives the compression mechanism and is housed within a motor housing. The drive shaft is engaged with the motor and the compression mechanism and is configured to drive operation of the compression mechanism. The motor cooler is disposed adjacent the motor and is configured to pump a cooling working fluid around the motor. The motor cooler includes a pump that pumps the cooling working fluid into the motor housing based on a rotational speed of the drive shaft.

    Abstract: A heat-pump system may include a compressor, an outdoor heating exchanger, an indoor heat exchanger, an expansion device, and a supplemental heater. The outdoor heat exchanger may be in fluid communication with the compressor. The indoor heat exchanger may be in fluid communication with the compressor. The expansion device may be in fluid communication with the indoor and outdoor heat exchangers. The supplemental heater may include a burner and a working-fluid conduit. The burner may be configured to burn a fuel and heat the working-fluid conduit. When the heat-pump system is operating in a heating mode, the indoor heat exchanger may receive working fluid from the working-fluid conduit such that the working fluid flows from an outlet of the working-fluid conduit to an inlet of the indoor heat exchanger.

    Abstract: A mitigation verification system includes: a control module configured to selectively transition a mitigation device of a refrigeration system of a building from a first state to a second state; and a verification module configured to verify and generate an indicator of whether the mitigation device of the refrigeration system transitioned from the first state to the second state based on a change in a parameter of the refrigeration system over a period in response to the transition by the control module.

    Abstract: A compressor 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 a suction inlet. The conduit directs working fluid into the suction inlet and includes a first end defining an inlet opening and a second end defining an outlet opening adjacent to the suction inlet. The second end includes a locating pin that extends outwardly therefrom.
