    Abstract: A vehicle having a heating and cooling system includes a refrigerant loop having first and second heat exchangers, and a coolant loop. The coolant loop is connected to allow a first flow of coolant to be directed through at least one of a plurality of air-to-coolant heat exchangers and at least one component for regulating a temperature of the at least component, and to allow a second flow of coolant to be directed through at least one other of the plurality of air-to-coolant heat exchangers and the at least one component for regulating the temperature of the at least one component dependent upon a mode of operation. A control module, control unit, controller, or the like commonly used in vehicles controls the first and second flows of coolant dependent upon the mode of operation.

    Abstract: A vapor injection heat pump includes a coolant loop and a refrigerant loop. The refrigerant loop includes a compressor, a valve directing a refrigerant of the compressor to a first or second heat exchanger dependent upon a mode of operation, an expansion device receiving the refrigerant from at least one of the heat exchangers, a separator receiving an expanded liquid/vapor refrigerant mix from the expansion device and directing a vapor component to a first input port of the compressor and a liquid component to a second valve. The second valve directs the liquid component to the heat exchangers, dependent upon the mode, and an accumulator receives an output refrigerant of the heat exchangers dependent upon the mode and directs a vapor component to a second input port of the compressor. A control module controls a pump in the coolant loop and the first and second valves dependent upon the mode.

    Abstract: 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.

    Abstract: A method of operating a stop-start vehicle with an HVAC system that does not include an electric auxiliary coolant pump for circulating warm coolant to a heater core of the HVAC system in an engine-off condition of the vehicle comprises the steps of driving the vehicle via compulsion by an engine in an environment having an ambient outside temperature of about or less than 30 degrees Fahrenheit, entering an auto stop event, such that the engine enters the engine-off condition, and circulating heated air into a cabin of the vehicle in the engine-off condition for at least one minute. The heated air is circulated by decreasing the speed of a blower motor, adjusting a recirculation door position to increase air recirculation, and adjusting a temperature blend door position toward a full-heat position based on a sensed engine coolant temperature and a sensed evaporator core temperature.
