Abstract: 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.

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 vehicle having a heating and cooling system includes a refrigerant loop having first and second heat exchangers, and a coolant loop. The coolant loop includes a plurality of valves directing a first flow of coolant through a first refrigerant-to-coolant heat exchanger, a second flow of coolant through a second refrigerant-to-coolant heat exchanger, and a third flow of coolant including a first portion of the first flow of coolant exiting the first refrigerant-to-coolant heat exchanger and a first portion of the second flow of coolant exiting the second refrigerant-to-coolant heat exchanger through an auxiliary coolant loop, and a control module for controlling the plurality of valves to direct the flows of coolant dependent upon a mode of operation. The auxiliary coolant loop is for heating/cooling one or more components, such as a battery, dependent upon the mode of operation.

Abstract: A vehicle having a heating and cooling system includes a refrigerant loop having first and second heat exchangers, a compressor, and an expansion device, and a coolant loop. The coolant loop is connected, in one embodiment, to allow a first flow of coolant to be directed through each of a plurality of heat exchangers and an auxiliary coolant loop and to allow a second flow of coolant to be directed through each of the plurality of heat exchangers and the auxiliary coolant loop dependent upon a mode of operation. A control module controls the first and second flows dependent upon the mode of operation. In one other embodiment, the coolant loop includes manifolds and reservoirs with regulating sending and receiving ports for directing the flows. The auxiliary coolant loop is for heating/cooling one or more components, such as a battery, dependent upon the mode of operation.

Abstract: A method of forming a superhydrophobic layer on a motor vehicle heat exchanger housing includes the steps of flowing a precursor gas of a mixture of heptadecafluoro-1,1,2,2-tetrahydrodecyl, trimethoxysilane (HTMS) and a carrier gas into a reaction chamber and depositing the superhydrophobic layer on the motor vehicle heat exchanger housing by chemical vapor deposition. A heat exchanger having a heat exchanger housing with a superhydrophobic layer made by the chemical vapor deposition method is also disclosed.

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.
