Features for a vapor compression system configured to cool and/or heat (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 heating, ventilating, and air conditioning (HVAC) system of a vehicle is provided. The system replaces a cooling water circuit having a complex configuration and a separate heat pump system for recovering waste heat of an electric vehicle by changing an air flow path for supplying heating and cooling air and secures an indoor space by disposing an HVAC in an engine room.

A system is provided. The system includes an inlet providing a first medium; a compressing device comprising a compressor, and at least one heat exchanger located downstream of the compressor. The compressing device is in communication with the inlet providing the first medium. The at least one heat exchanger includes a first pass and a second pass. An outlet of the first pass of the at least one heat exchanger is in fluid communication with an inlet of the compressor.

Disclosed is a ventilation module for improving the efficiency of a vehicle HVAC system. The ventilation module includes a return air duct having an outlet to be coupled to the HVAC system. The ventilation module also includes a fresh air duct, a heat exchanger, and first and second doors. The first and second doors connect the return and fresh air ducts upstream and downstream of the heat exchanger. By selectively opening or closing the first and second doors, the ventilation module provides the HVAC system with desired return, fresh or mixed air through the outlet of the return air duct.

Disclosed is a heat exchanger capable of exchanging heat between coolant and refrigerant of different kinds in one device and providing an effective heat exchange ratio between the coolant and the refrigerant. The heat exchanger includes a refrigerant flow path having a refrigerant inlet and a refrigerant outlet, and a coolant flow path through which coolant flows to exchange heat with the refrigerant. The coolant flow path includes a first coolant flow path where first coolant flows, and a second coolant flow path where second coolant with a different kind from the first coolant flows. The heat exchanger is partitioned into a first heat exchange section, in which the first coolant exchanges heat with the refrigerant and a second heat exchange section, in which the second coolant exchanges heat with the refrigerant, so that the heat exchange in the first heat exchange section and the heat exchange in the second heat exchange are carried out independently.

A hybrid vehicle, a front cabin and a method for controlling the front cabin are provided. The front cabin includes: a sheet metal and a front subframe. The front cabin is configured to house an engine, a motor, a motor controller, a transmission and a support assembly. The engine and the motor are connected to the transmission respectively; the engine is disposed on the right side of the front cabin; the transmission is disposed on the left side of the front cabin; the motor is disposed on the left side of the front cabin and above the transmission; and the motor controller is disposed above the transmission and located at the front of the motor.

A heat conducting device in a vehicle whereby heat in the body or shell of the vehicle is transferred to the ground includes a control device, a heat transferring device, and a driving device. The heat transferring device is in the vehicle and is connected to the shell of the vehicle when the vehicle is flameout, the driving device is coupled to the control device and the heat transferring device, such that the heat transferring device is extended downwards from the vehicle, until the heat transferring device contacts the ground, thereby heat of the shell of the vehicle is transferred to the ground.

A refrigerant loop of a vapor injection heat pump includes a compressor, first and second expansion valves, and first and second separator valves. The separator valves allow an entire refrigerant flow to pass therethrough or operate to separate vapor and liquid components of expanded refrigerant and inject the vapor component into a suction port of the compressor. Vapor injection occurs in both heating and cooling modes of operation and may depend upon an ambient condition (e.g., high or low ambient temperatures). An accumulator receives an output refrigerant of the heat exchangers dependent upon the mode and directs a vapor component into another suction port of the compressor. A control module controls at least the first and second expansion valves and first and second separator valves dependent upon the mode of operation which include, among others, heating, cooling, and dehumidification and re-heating.

An air cleaning apparatus mounted to an internal automobile structure selected from an armrest, a console, a seat, a headrest, an overhead console, a handle, and a door, includes an air inflow unit arranged in the internal automobile structure, through which air inside an automobile is introduced, an air cleaning unit which is arranged in the internal vehicle structure and filters the introduced air inside the automobile, a first air flow path arranged in the internal automobile structure, through which the air, having been introduced through the air inflow unit and filtered by the air cleaning unit, is discharged to the interior of the automobile, and a second air flow path arranged in the internal automobile structure, through which blowing air, having been introduced to the internal automobile structure and not having passed through the air cleaning unit, is discharged to the interior of the automobile.

A HVAC system for a vehicle that includes a propulsion system, a frame, a passenger compartment, and a door coupled to the frame. The HVAC system includes a refrigeration circuit that selectively controls the temperature of the passenger compartment based on a sensed temperature within the passenger compartment. The refrigeration circuit includes an exterior heat exchanger, a first air moving device coupled to the exterior heat exchanger, an interior heat exchanger, a second air moving device coupled to the interior heat exchanger, and a compressor. The HVAC system also includes a controller that is operable to detect a condition of the vehicle that includes at least one of a position of the door, a location of the vehicle, and a load of the propulsion system. The controller is programmed to adjust the refrigeration circuit in response to the sensed passenger compartment temperature and the detected vehicle condition.
