In an internal combustion engine, a gasket is disposed between joining surfaces of a cylinder block and a cylinder head, and a heat radiation rib that extends in a cylinder axis direction is formed on the cylinder block or the cylinder head. In such an internal combustion engine, the gasket includes: a portion to be sandwiched that is sandwiched between the joining surfaces; and an extending portion that protrudes toward an outside from the portion to be sandwiched as viewed in a cylinder axis direction.

A climate control system includes a plurality of vent registers, an HVAC unit delivering conditioned air to the plurality of vent registers, a side door status monitoring device and a controller configured to control opening and closing of the plurality of vent registers in response to side door status data provided by the side door status monitoring device. A related climate control method is also provided.

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 motor vehicle air-conditioning system includes a housing for guiding an air flow, wherein air outlets for the air supply into the motor vehicle interior are formed. An evaporator through-flowable by the air flow, and a thermal heat exchanger arranged in the housing downstream of the evaporator. A cold air path bypassing the thermal heat exchanger and a warm air path running through the thermal heat exchanger lead downstream into a mixing space connected to the air outlets. At least one separating wall runs through the housing and separates the housing into at least two flow areas along the cold air path, the warm air path, the mixing space and the air outlets. Air outlet areas can be closed and opened by means of operating flaps, and an air bypass can be closed and opened for a direct fluidic connection between at least two temperature zones.

A front and rear integrated vehicle HVAC system includes a front HVAC portion with a front blower and a front vent outlet, and a rear HVAC portion with a rear blower and a rear vent outlet. The system includes a controller that determines a minimum voltage to be supplied to the rear blower to prevent an inverse air flow from being expelled from the rear outlet and/or a rear blower air intake. A voltage supplied to the rear blower is then set as the greater of the minimum rear blower voltage and a current rear blower voltage. The inverse air flow is air flow in the front HVAC portion generated by the front blower and intended for the front vent outlet that seeps into the rear HVAC portion and is expelled from the rear vent outlet and/or the rear blower air intake.

A discharged air flow path connected to a cooling fan has a first discharged air flow path which is connected to at least one side trim of a left side trim and a right side trim and a second discharged air flow path which branches off from the first discharged air flow path and which is connected to the side trim. A first connecting portion which connects the first discharged air flow path and the side trim is disposed so as to be spaced away from a second connecting portion which connects the second discharged air flow path and the side trim in a front-rear direction. The first discharged air flow path and the second discharged air flow path discharge air into a passenger compartment by way of the side trim.

The present disclosure provides a casing for an air conditioning unit including a main body, a door, a passing defining member, and a drain channel. The main body includes a fresh-air passage and a recirculation-air passage. The recirculation-air passage is positioned below the fresh-air passage. The door selectively opens and closes a communication hole through which the fresh-air passage and the recirculation-air passage are in fluid communication with each other. The passage defining member is disposed upstream of the communication hole and defines a lower side of the fresh-air passage. The drain channel extends from the passage defining member to a space outside of the recirculation-air passage to discharge condensed water generated in the fresh-air passage.

A heating, ventilation and/or air-conditioning apparatus (1) for the passenger compartment of a motor vehicle includes a housing (2) comprising a first air inlet (3) and a second air inlet (4). The housing (2) directs an inner air flow (Fi) from the first air inlet (3) and/or the second air inlet (4) and contains at least a first heat exchanger (5). The housing (2) includes: an air flow channel (24) directing the inner air flow (Fi) in the housing (2) while bypassing the first heat exchanger (5); and an air inlet duct (23) directing the inner air flow (Fi) in the housing (2) through the first heat exchanger (5). A heating, ventilation and/or air-conditioning installation for the passenger compartment of a motor vehicle includes: an air conditioning loop through which a coolant flows. The loop includes at least one compressor, a first expansion member, an outer heat exchanger and the first heat exchanger (5). The installation also includes the heating, ventilation and/or air-conditioning apparatus (1).

An air conditioner for a vehicle which can block air introduced through a gap between an evaporator and an air-conditioning case and prevent condensate from overflowing toward a temperature adjusting door when condensate exceeding a drainable amount is generated. The air-conditioning case has an air passageway therein. An evaporator is disposed in the air passageway. A drain hole is disposed at a downstream side of the evaporator in an air flow direction to discharge condensate to the outside. A first baffle protrudes upwardly from a bottom surface of the air-conditioning case for preventing air from leaking between the air-conditioning case and the evaporator.

An air blowing device has a first blowing portion, a duct, and an airflow causing member. The first blowing portion has a guide surface and is provided with a first blowing outlet that blows air from a blower unit into a vehicle compartment. The airflow causing member defines at least one of a first passage and a second passage located on one side and an other side of the airflow causing member in a front-rear direction of a vehicle respectively in the duct. The airflow causing member sets a first condition in which a high-velocity airflow flows in the first passage and a low-velocity airflow flows in the second passage by decreasing a sectional area of the first passage to be smaller than a sectional area of the second passage. The high-velocity airflow flows along the guide surface and is blown into the vehicle compartment.
