An ejector-type refrigeration cycle includes an ejector module integrated with a gas-liquid separation device. The ejector module is disposed outside an area that overlaps with an engine when viewed from a vehicular upper side. Further, the ejector module may be disposed outside an area overlapping with the engine when viewed from the vehicular front side, and the ejector module may be disposed outside of side members in a vehicle width direction.

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.

Systems and methods are provided for controlling a hybrid powertrain of a hybrid vehicle, and may include: determining a value of a drive request for a combustion engine of the hybrid vehicle; determining electrical loading on batteries of the hybrid vehicle; adjusting operation of an accessory of the hybrid vehicle to reduce the electrical load of that accessory on the batteries of the hybrid vehicle when the drive request value is above a determined drive request threshold amount and the electrical loading on batteries of the hybrid vehicle is above a power loading threshold; and directing at least some of the power saved by adjusting operation of the accessory from the batteries of the hybrid vehicle to a drive motor of the hybrid vehicle to provide motive force for the vehicle.

An integrated thermal management system for mobility vehicles, may include a hybrid compressor including a mechanical compression unit driven using the driving force of an engine, and an electric compression unit driven using the driving force of a motor and configured such that an air blower is connected to the electric compression unit, a refrigerant circulation line fluidically-connected to the hybrid compressor, a condenser and an expansion valve such that a refrigerant circulates thereto, and an indoor air conditioning unit configured to cool or heat air introduced through the air blower and then to discharge the air to the inside of a mobility vehicle and including a cooling core connected to a point of the refrigerant circulation line downstream of the expansion valve of the refrigerant circulation line and a heating core fluidically-connected to an exhaust gas discharge line connected to the engine.

Features for a vapor compression system configured to cool and/or cat (i.e. thermally condition) two or more distinct climate controlled vehicle interior components via a common thermal bus are disclosed. Some embodiments employ a single compressor. Some embodiments employ multiple compressors and/or thermal buses, each servicing components located within respective interior thermal zones of a vehicle, for example a front row seat zone, second and/or third row seat zones, and/or an overhead zone and/or a trunk zone.

A method for heating and/or air-conditioning in a motor vehicle interior by means of a reversible refrigeration loop in which a refrigerant fluid circulates, said fluid including: between 4 and 6 wt. % of difluoromethane (HFC-32); between 2.5 and 3.5 wt. % of pentafluoroethane (HFC-125); and between 91 and 93.5 wt. % of tetrafluoropropene, preferably 2,3,3,3-tetrafluoropropene.
