A vehicle has a drive motor and a refrigerant circuit. The refrigerant circuit includes, when viewed in the direction of flow of the refrigerant, a compressor, a gas cooler or condenser, an expansion device and an evaporator. The refrigerant circuit has a first shut-off element which is arranged outside of an area arranged between the drive motor and the evaporator.

A cooling assembly for under a vehicle is provided. The cooling assembly includes a housing, a slab condenser, and a condenser fan. The housing is configured to be attached under and to a floor of the vehicle. The housing includes a top wall, side walls and a bottom wall. The slab condenser is disposed within the housing and horizontally oriented when the housing is attached to the vehicle. The condenser fan assembly is disposed within the housing and directing air vertically through the top wall, the bottom wall and the slab condenser.

The present invention relates to an internal heat exchanger double-tube structure of an air conditioning system having an alternative refrigerant applied thereto for heat exchange between a low-temperature low-pressure refrigerant discharged from an evaporator and a high-temperature high-pressure refrigerant discharged from an condenser, the double-tube structure including: an inner pipe having a channel through which the low-temperature low-pressure refrigerant discharged from the evaporator flows; and an outer pipe surrounding the inner pipe and having a channel through which high-temperature high-pressure refrigerant flows, wherein the inner pipe has a spiral groove forming a channel on an outer side thereof, and the spiral groove is a recessed groove for generating a vortex that increase a channel volume where high-temperature high-pressure liquid flows inward and reduces a vortex of flowing fluid.

An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. A length of an inlet pipe that connects a liquid-phase refrigerant outflow port of an ejector module to a refrigerant inflow port of an evaporator is shorter than a length of a suction pipe that connects a gas-phase refrigerant outflow port of the ejector module to a suction port of the compressor.

An integrated energy management unit includes a housing defining a housing cavity, an accumulator-separator positioned within the housing cavity, an ejector positioned within the housing cavity and in communication with the accumulator-separator, and an internal heat exchanger positioned within the housing cavity and in fluid communication with the accumulator-separator.

A heat pump system includes a compressor, a fluid switching device, a first heat exchanger, a second heat exchanger, a third heat exchanger, a fourth heat exchanger, a flow regulating device and a throttle element. The second heat exchanger includes a first heat exchange portion and a second heat exchange portion. An outlet of the first heat exchange portion communicates with the throttle element. An inlet of the first heat exchange portion communicates with at least one of a second port of the third heat exchanger and an outlet of the fourth heat exchanger. An inlet of the second heat exchange portion communicates with the outlet of the first heat exchanger. An outlet of the second heat exchange portion communicates with an inlet of the compressor. In a heating mode, the function of the second heat exchanger is reduced, thereby the heating capacity of the heat pump system is improved.

A vehicle air conditioning system provides a heat exchanger and a vehicle air conditioning system comprising same, which can simplify the overall structure and can easily perform cooling/heating of air for air conditioning and dehumidification heating by using an integrated heat exchanger which is selectively supplied with low- and high-temperature cooling water by a supply valve to perform heat exchange.

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.

A power generation module of a vehicle air-conditioning system is provided. The air-conditioning=includes a compressor, a condenser, an expansion valve, and an evaporator. The power generation module includes a high-temperature flow channel through which a refrigerant in a high-temperature state flows and a low-temperature flow channel through which a refrigerant in a low-temperature state compared with the high-temperature flow channel flows. A thermoelectric module is provided in which heat of the high-temperature flow channel is transferred to a first side thereof, heat of the low-temperature flow channel is transferred to a second side thereof, and an electromotive force is generated by a temperature difference between the first and second sides due to the transferred heat.

A valve-in-receiver (VIR) for a vehicle climate control system includes a receiver drier (RD) shell including an outer surface and an inner surface defining an interior portion having an opening, and a cap member mounted to the RD shell across the opening, the cap member including an evaporator inlet portion, an evaporator outlet portion, a condenser inlet and a compressor outlet.
