摘要： A heat pump includes a refrigerant loop. The refrigerant loop includes an accumulator having an inlet and an outlet, a compressor, a first heat exchanger, and a first coupling point. The compressor includes a low-pressure inlet and an outlet. The low-pressure inlet is downstream of the outlet of the accumulator. The first heat exchanger includes an inlet and an outlet. The first coupling point is positioned immediately downstream of the outlet of the accumulator and immediately upstream of the low-pressure inlet of the compressor. The first coupling point is immediately downstream of the outlet of the first heat exchanger such that a first heat exchange fluid circulating through the refrigerant loop is directed to the low-pressure inlet of the compressor upon exiting the outlet of the first heat exchanger.

摘要： A cold ambient battery chilling mode of an electric vehicle may be implemented if the vehicle battery is being charged when the ambient air temperature is low and a temperature of the battery is elevated. During cold ambient charging, coolant flows through a heater core and through a battery heat exchanger. Cold ambient air may be utilized to cool the coolant flowing through the heater core, and coolant from the heater core flows through the battery heat exchanger and cools the battery during charging. A battery chiller may be deactivated when the cold ambient battery chilling mode is activated to reduce energy consumption.

摘要： A heat pump includes a refrigerant loop. The refrigerant loop includes a compressor, a first condenser, a vapor generator having a first region and a second region, a first expansion valve, a second expansion valve, and a first evaporator. A branching point is positioned between the first condenser and the vapor generator. The branching point diverts a portion of a first heat exchange fluid circulating through the refrigerant loop to the vapor generator. The first expansion valve is positioned between the branching point and the vapor generator. An outlet of the vapor generator is coupled to a mid-pressure inlet port of the compressor.

摘要： This disclosure relates to an electrified vehicle having a cabin pre-cooling strategy for managing battery and cabin cooling loads. A corresponding method is also disclosed. An example electrified vehicle includes a battery for propulsion, a cabin, a thermal management system configured to thermally condition both the battery and the cabin, and a controller configured to follow a cabin pre-cooling strategy to pre-cool the cabin when an expected cooling load of the battery, if the electrified vehicle were to be driven in present conditions, exceeds an upper battery cooling load threshold.

摘要： A vehicle HVAC system including a heat pump system. The heat pumps system including a refrigerant module mounting manifold, the manifold including a first plate and a second plate. The first plate and the second plate are configured to couple together such that together they define a plurality of channels for directing the flow of refrigerant through the heat pump system. One or more auxiliary modules are fluidly coupled to the refrigerant module mounting manifold.

摘要： A respirator includes a head unit configured to be received on a human head and a purifying unit configured to provide purified air to the head unit. The purifying unit includes a first housing portion having an interior side defining a blower cavity, an exterior side defining a partial filter chamber with a filter sealing surface, and an inlet hole circumscribed by the sealing surface and extending between the interior and exterior sides. A second housing portion has an interior side defining a blower cavity. The first and second housings are attached to each other to form a housing such that the blower cavities are opposite each other to define a blower chamber within the housing. A blower is disposed in the blower chamber. A filter covers over the inlet hole and is disposed against the sealing surface such that air entering the hole passes through the filter.

摘要： A vehicle air-handling system includes a heat exchanger, a blower in communication with the heat exchanger, and an operable duct having driver and passenger portions that are each in communication with the heat exchanger and the blower. When the blower is activated, the driver portion continuously delivers blower air and the passenger portion selectively delivers blower air.
