The disclosed embodiments include a vehicular ventilation module having control circuitry, a return air duct, a fresh air duct, a heat exchanger, and a door joining an upstream portion of the return air duct upstream of the heat exchanger and an upstream portion of the fresh air duct upstream of the heat exchanger. The fresh air duct has an air inlet and an air outlet downstream of the air inlet. The heat exchanger is thermally coupled to the return air duct upstream of the return air outlet and to the fresh air duct downstream of the return air inlet. The door selectively opens to enable air to pass between the fresh air duct and the return air duct. The control circuitry is configured to operate in a first mode of operation, including having the door open. The return air outlet is configured to provide air to the HVAC system.

A heat exchanger with a heat transfer area, with a fluid collector and with a valve unit. The heat transfer area has a first fluid path for a first fluid flow and a second fluid path for the second fluid to flow through. The first fluid path is in thermal contact with the second fluid path for heat transfer between the first fluid and the second fluid. The fluid collector has a first fluid inlet and a first fluid outlet for the inflow of the first fluid into the fluid collector for the storage of the first fluid in the fluid collector and for the outflow of the first fluid from the fluid collector. The valve unit is provided and designed to control the fluid flow through the heat transfer area and/or the fluid collector. The heat transfer area, the fluid collector and the valve unit are designed as a single unit.

Electric vehicle thermal management systems and electric vehicles using the thermal management system, are disclosed. A passenger cabin is heated by the heat dissipated from a battery and/or a motor. A cooling circuit in the management system fluidly connects the battery, the motor and a first radiator in series. The first radiator provides a heat source to the passenger cabin by means of the heat dissipated from the battery and/or the electric motor. Under certain conditions, the electric motor is selectively separated from the cooling circuit, so that when the passenger cabin needs to be heated, the thermal management system can provide heat to the passenger cabin without affecting the heat dissipation of the battery.

A vehicle has a climate control system using a heat pump having a condenser heat exchanger that exchanges heat between refrigerant and working fluid within a hot fluid chamber, and an evaporator heat exchanger that exchanges heat between refrigerant and working fluid within a cold fluid chamber. A super-heated fluid pressure vessel may be in fluid communication with the cold fluid chamber by way of a heat exchanger and an electrically controlled variable delivery valve, and has an electric heater that may be powered by a drivetrain battery or by a shore power source. The hot fluid chamber provides heat to at least one cabin heat exchanger and to at least one ambient air heat exchanger. The cold fluid chamber is connected to at least one vehicle interior cooling module, to a waste heat source, and to a cold fluid chamber to outside heat exchanger.

An electric or hybrid electric vehicle has a climate control system using a heat pump having a condenser heat exchanger that exchanges heat between refrigerant and working fluid within a hot fluid chamber, and an evaporator heat exchanger that exchanges heat between refrigerant and working fluid within a cold fluid chamber. An insulated fluid reservoir may selectively be placed in fluid communication with the cold fluid chamber, and has a Positive Temperature Coefficient (PTC) heater that may be powered by a drivetrain battery unit or by a shore power source. The hot fluid chamber provides heat to at least one cabin heat exchanger and to at least one ambient air heat exchanger. The cold fluid chamber is connected to at least one vehicle interior cooling module and to a liquid cooled heat sink that may cool an electric motor and power electronics of the vehicle.

An air purification device includes: a carbon dioxide removal device configured to sorb and remove carbon dioxide contained in air; an air supply duct connected to a first outlet of the carbon dioxide removal device and having a blowing opening 17a for flowing out purified air from which carbon dioxide has been removed by the carbon dioxide removal device 12 into a vehicle cabin; and an exhaust duct connected to a second outlet of the carbon dioxide removal device and having an exhaust opening 18a for discharging the carbon dioxide sorbed by the carbon dioxide removal device to outside of the vehicle cabin 3, wherein the air supply duct is mounted to a front seat of the vehicle so as to be movable vertically with the blowing opening facing forward.

A climate control system includes a front-end or first heat exchanger configured to thermally condition airflow from an environment external to a cabin, a rear-end or second heat exchanger configured to thermally condition airflow from the cabin, a recirculation path configured to return airflow from the second heat exchanger to the cabin, and an extraction path configured to vent airflow from the second heat exchanger to the environment external to the cabin. Various operational modes of the climate control system direct airflow to either the recirculation path or the extraction path.

A heat pump air-conditioning system includes a (HVAC) assembly, a compressor, an outdoor heat exchanger, and a first plate heat exchanger. The HVAC assembly includes an indoor condenser, an indoor evaporator, and an damper mechanism. The compressor communicates to the indoor condenser. The indoor condenser communicatees to the outdoor heat exchanger and further to the outdoor heat exchanger through a first enthalpy-increased branch. The outdoor heat exchanger communicates to the indoor evaporator and further to a moderate-pressure air inlet of the compressor through a second enthalpy-increased branch. The indoor evaporator communicates to a low-pressure air inlet of the compressor. The first enthalpy-increased branch and the second enthalpy-increased branch exchange heat by using the first plate heat exchanger. The second enthalpy-increased branch is provided with a first expansion valve. The outdoor heat exchanger is in communication with the first plate heat exchanger through the first expansion valve.

An apparatus for cooling a battery for a vehicle is provided. The apparatus includes a battery module for a vehicle and a body that is disposed adjacent to the battery module. The body has a circulation space formed therein to allow heat generated in the battery module to circulate in the circulation space and thus be absorbed by the body. Additionally, a cooling part is disposed to exchange heat with the body to thus cool the battery module is introduced.
