An air-conditioning unit for a vehicle includes an air conditioning case, a blower, and a rectifying mechanism. The blower has a blower fan rotating around a fan axis and arranged in an in-case passage of the air conditioning case, and blows out air drawn from one side in an axial direction of the fan axis by rotation of the blower fan. The rectifying mechanism is arranged downstream of the blower fan in the in-case passage, and the air passes through the rectifying mechanism. The blower fan is arranged so that the other side of the fan axis that is opposite to the one side extends toward a downstream side of the in-case passage. The rectifying mechanism suppresses a swirling flow generated by the rotation of the blower fan in the air blown out from the blower fan as compared with the blown-out air prior to flowing into the rectifying mechanism.

An air conditioning unit for a vehicle includes a first channel and a second channel, a blowing unit including a first blower fan and a second blower fan that rotate together by sharing a rotary shaft and a driving unit, a bypass channel, and a control door disposed among the outlets of the first channel and the second channel, the heating core, and the bypass channel to control air discharged from the first channel or the second channel to pass through the heating core or not to pass through the heating core through the bypass channel.

An air ventilation device of a vehicle includes: a housing including an air inlet and an air outlet and a cooling core and a heating core disposed between the air inlet and the air outlet; a rear extending flow path extending to the rear of the vehicle, and having a first end connected to the air outlet of the housing and a second end connected to a back seat air vent disposed to face a back seat space; an air collecting flow path directly connecting the rear extending flow path and the air inlet of the housing; and an opening and closing door structure opening and closing air circulation between the rear extending flow path and the air outlet and air circulation between the air collecting flow path and the air inlet.

An HVAC system including a defrost manifold. The defrost manifold has a first side window outlet, a second side window outlet, and a windshield outlet. A first rib partially obstructs the first side window outlet. A second rib partially obstructs the second side window outlet. A control door is movable to open and close the defrost manifold. A first wall extends from a first portion of the control door that is opposite to the first side window outlet. A second wall extends from a second portion of the control door that is opposite to the second side window outlet. Movement of the control door varies the position of the first wall relative to the first rib, and varies the position of the second wall relative to the second rib, to control airflow through the first and second side window outlets.

A process for making an alcohol-containing frozen comestible substantially devoid of ice crystal agglomerations and/or ice crystal striations and/or trapped air and/or liquids is provided. The process includes substantially flash freezing an alcohol-containing liquid composition so as to produce a substantially single-phase solid alcohol-containing composition. The solid alcohol-containing composition, and/or pieces thereof, are then exposed to an environment having temperature of from about 15 C. to about 30 C. so as to soften the solid alcohol-containing compositions and/or meld the pieces thereof into a single mass. The temperature of the single mass is then reduced so as to harden the single mass. Also, a process for incorporating a frozen alcohol-containing liquid composition into a non-alcohol-containing fraction is provided. Alcohol-containing liquid compositions suitable for use in the process are also provided.

A process for making an alcohol-containing frozen comestible substantially devoid of ice crystal agglomerations and/or ice crystal striations and/or trapped air and/or liquids and products thereof is provided. The process comprises rapidly solidifying an alcohol-containing liquid composition so as to produce a substantially single-phase solid alcohol-containing admixture. The single-phase solid alcohol-containing admixture, and/or pieces thereof, is then tempered by raising the temperature thereof so as to soften the single-phase solid alcohol-containing admixture and/or meld the pieces thereof into a single tempered mass. The single tempered mass is then re-hardened by reducing the temperature thereof. Also, a process for incorporating the single-phase solid frozen alcohol-containing admixture into a non-alcohol-containing composition is provided.

An airflow turning device with airflow control channels for an outlet of a heating, ventilation, and air conditioning (HVAC) case that directs airflow to a plurality of different vehicle outlets. The airflow control channels extend from an inner upstream side of the outlet to an outer downstream side of the outlet. Different ones of the plurality of channels have different lengths to generate a varied pressure drop at the outer downstream side in response to airflow blown into the plurality of channels from the inner upstream side.

Described herein is air distributing device for an air conditioning unit of a motor vehicle, the device including: a housing defining an air intake chamber, on the housing there being formed an air inlet, a central air outlet, and two side air outlets. The device also includes a drum flap mounted rotatably about an axis (z) orthogonal to a direction that goes from the air inlet to the central air outlet. The flap is movable between a first position, wherein the air inlet is closed by the flap; a second position, wherein the two side air outlets are closed by the flap and an air flow between the air inlet and the central air outlet is allowed; and a third position, wherein the central air outlet is closed by the flap and an air flow between the air inlet and the side air outlets is allowed.

An air flow control for a ventilation, heating, or air conditioning unit of a motor vehicle, having a housing with a cold air passage with a first inlet opening and with a hot air passage with a second inlet opening. At least one heating heat exchanger is disposed in the hot air passage in order to heat the air in the hot air passage with a mixing chamber for mixing a first partial air flow from the cold air passage and/or a second partial air flow from the hot air passage. The mixing chamber is disposed downstream of the hot air passage and of the cold air passage. A mixing flap substantially closes the first inlet opening. The housing downstream of the mixing chamber has a first outlet opening and at least one second outlet opening for the flowing of air out of the mixing chamber.

A vehicle includes a heating, ventilation and air conditioning (HVAC) system for heating and cooling a passenger compartment. The HVAC system includes a refrigerant loop and a coolant loop, and an auxiliary heating, ventilation and air conditioning (HVAC) system. The auxiliary HVAC includes an expansion device coupled to the refrigerant loop for controlling a flow of refrigerant to a first heat exchanger, and a second heat exchanger coupled to an auxiliary coolant loop used to regulate a temperature of the component. The auxiliary HVAC further includes a blower for creating an air flow through the first heat exchanger, a first blend door for directing the air flow through the second heat exchanger and/or an outlet, a second blend door for directing the air flow through the outlet and/or a recirculation duct, and a third blend door for controlling the air flow through the recirculation duct.
