摘要： A vehicle HVAC system includes a compressor, a first heat exchanger for exchanging heat between the refrigerant outside air, a first check valve set, a first expansion device for decompressing a first portion of the refrigerant, a second heat exchanger for exchanging heat between the first portion of the refrigerant and a second portion of the refrigerant, a second expansion device for decompressing the second portion of the refrigerant, a second check valve set, a third heat exchanger for exchanging heat between the refrigerant and inside air, and a selector valve for switching between a heating mode and a cooling mode. The first check valve set and the second check valve set together maintain a constant flow direction through the first expansion device, the second heat exchanger, and the second expansion device in the heating mode and the cooling mode.

摘要： A vehicle heat pump system including a thermal loop, an eight-way valve, and a controller is provided. The thermal loop includes a compressor, a first portion, and a second portion. The first portion includes an outside heat exchanger. The second portion includes a cabin heat exchanger. The eight-way valve is downstream of the compressor and has a first position in which refrigerant flows within the portions in a cooling mode and a second position in which refrigerant flows within the portions in a heating mode. The controller switches the eight-way valve between the first and second positions. The outside heat exchanger operates as a condenser in the cooling mode and the eight-way valve directs refrigerant flow from the outside heat exchanger to the cabin heat exchanger.

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 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： A multi-compressor refrigerant system for a vehicle including a main compressor, an auxiliary compressor fluidly coupled with the main compressor, and a chiller fluidly coupled to the main compressor and the auxiliary compressor for exchanging heat with an electronic device. At least one of the main compressor and the auxiliary compressor is operated based on a thermal load of the chiller.

摘要： A vehicle includes an interior and a controller configured to control a climate system for the interior based at least in part on data related to a departure location of the vehicle, a destination location of the vehicle, or a proximate location within a certain proximity to the vehicle, while moving to the destination location between the departure location and the destination location, or any combination of said locations. The data related to the departure location can include a temperature profile of the departure location. The temperature profile of the departure location can assume that the departure location is colder than a comfortable ambient temperature, and the controller is configured to direct heated air into the interior upon activation of the vehicle at the departure location. The data related to the departure location can include an activity profile of the departure location.
