The present invention relates to an air conditioner for a vehicle can enhance sealing performance and is resistant to noise and vibration, and prevent penetration of water into the interior of the vehicle by inducing water introduced into a seal into an air-conditioning case by a pressure difference. The air conditioner for a vehicle, which has a structure that a pipe of a heat exchanger penetrates through a dash panel (150) of the vehicle, includes: a bracket (140) for inserting and fixing the pipe; and a seal (160) for fixing the bracket (140) between an air-conditioning case and the seal to get in contact with the air-conditioning case.

A vehicle air conditioner includes an air-conditioning case having a drain hole through which an air passage communicates with an outside of a vehicle compartment, a heat exchanger disposed inside the air passage, and a seal member. The seal member is held between a dash panel and a seal wall of the air-conditioning case. The seal member has a through hole, and closes a through hole of the dash panel. The vehicle air conditioner includes a refrigerant pipe and a pressure reducing valve. The first case part and the second case part are fitted with each other in a fitting part below which, in the vertical direction, the air-conditioning case has a communication hole through which an outside of the air-conditioning case communicates with the air passage.

An arrangement for sealing functional unit interfaces includes a functional unit, an interface, and a sealing element. The interface has a first main surface, a second main surface, and an opening. The second main surface has a clamping section enclosing the opening. The functional unit has a front face with a counter-clamping section opposite the clamping section. The sealing element has a sealing body and a support element at least partially arranged within the sealing body. The sealing body has a first section clamped between the clamping section and the counter-clamping section. The opening is closed by a second section of sealing body, which is at least partially arranged between the opening and the front face. The support element is partially arranged in the first section and partially in the second section of the sealing body. The support element and the sealing body consist of different materials.

A split heating, ventilation, and air-conditioning (HVAC) assembly for a motor vehicle is disclosed. The split HVAC includes a first sub-assembly comprising an evaporator and a first airflow space, a second sub-assembly comprising a second airflow space, a single sealing element located between a wall and one of the first sub-assembly or the second-sub-assembly, and a first interfacing element that directly connects the first sub-assembly and the second sub-assembly. The single sealing element and the first interfacing element prevent any airflow leakage from both the first sub-assembly and the second sub-assembly, and one of the first sub-assembly and the second sub-assembly extends partially into the other of the first sub-assembly and the second sub-assembly.

A sealing element having a substantially right-angled exterior corner is formed from a preform. The preform is formed from a strip of sealing material including a first longitudinal side surface having a projection projecting therefrom and an oppositely arranged second longitudinal side surface having a notch formed therein. The notch is aligned with the projection with respect to the longitudinal direction of the strip. A first segment of the strip is formed to a first side of the projection and a second segment of the strip is formed to a second side of the projection. The projection forms the substantially right-angled exterior corner of the sealing element following a bending of the first segment perpendicular to the second segment.

A heating, ventilation, or air conditioning system having a housing , for a motor vehicle having a firewall, wherein the firewall has at least one opening, wherein the housing projects through the opening, wherein the housing has at least a first housing part and at least a second housing part, wherein the first housing part rests against the firewall with a seal interposed and is attached to the firewall, wherein a portion of the first housing part projects through the opening, and the second housing part is attached in a sealed manner to the portion of the first housing part that projects through the opening.

The present invention relates to a vehicle air conditioner having a photocatalyst module, i.e., a two-layered flow air conditioner in which an inner flow path of the air conditioner is divided into an upper flow path and a lower flow path, the air conditioner providing an optimal design location and a mounting structure of a photocatalyst module which are capable of purifying both the upper flow path and the lower flow path by using a minimum number of photocatalyst modules.

An HVAC assembly may include a base portion that includes a rib outwardly extending therefrom. The base portion and the rib may be formed of a first material having a first elongation to yield. The blower housing may also include a collapsible portion that is formed of a second material and fixed to the rib by a bond between the first and second materials. The second material may have an elongation to yield that is greater than the first elongation to yield of the first material and may be configured to collapse when a force is applied to the collapsible portion.

An air ducting system is provided for ducting an air flow emerging from an air vent, which serves to introduce an air flow directly into a passenger compartment of a vehicle, to a measuring device for measuring of at least one parameter of the air flow. The measuring device includes at least one collector unit for collecting the air flow emerging from the air vent, which can be arranged on the air vent in such a way that a contact face of the collector unit completely encloses at least one outlet aperture of the air vent. In order to improve a measurement of at least one parameter of the air flow, the air ducting system comprises at least two air duct units of different design, either of which can be connected to and non-destructively detached from the collector unit.

A connecting pipe is made from polymer material and is shaped to link an opening of an air inlet pipe of a thermal device of a motor vehicle and an opening of a firewall of the vehicle. The connecting pipe has a cross section equal to or greater than a cross section of the air inlet pipe. The connecting pipe has two open ends. The two open ends include a first open end having a first interface which is shaped to be assembled and fixed to the air inlet pipe, and a second open end having a second interface which includes a bearing surface which is shaped to be applied against the firewall on the periphery of the firewall opening.
