An HVAC system includes a blower housing including a blower inlet and a blower outlet, the blower housing having a plastic skeleton structure. The HVAC system further includes a foam blower liner disposed within and coupled to the blower housing.

A vehicle air-conditioning unit includes a seal compressing portion presses a sealing component against a partition wall that separates an interior and an exterior of a vehicle compartment. The seal compressing portion is positioned in the interior of the vehicle compartment and includes a tubing routing space through which inner tubing extends, and a drain space positioned below the tubing routing space to receive water drained from the tubing routing space. The drain space communicates with the exterior of the vehicle compartment via a through hole of the partition wall to discharge water from the drain space to the exterior of the vehicle compartment.

A heating, ventilation, and air-conditioning system for a vehicle includes a housing, a door supported by the housing, and a lock integral with the housing. The housing further includes a first air flow path and a second air flow path. The door moves between a first position blocking airflow from the first air flow path and a second position blocking airflow from the second air flow path. The lock is configured to automatically lock the door in the second position upon assembly of the housing.

The present invention relates to a component part of a climatization system or window system for a recreational vehicle, the component part covers a mounting frame of the climatization system or window system and the component part is selected from an air distribution unit that is configured to distribute air inside the recreational vehicle, a decorative window frame and a shading unit for adjusting the amount of incident light, the component part has one or more attachment portions which, in a mounted state, are accessible by the user from inside the recreational vehicle, wherein each of the one or more attachment portions is either connectable to one particular module or to a plurality of different modules in a mutually exchangeable manner, and wherein the modules include sensors for detecting events or parameter changes inside the recreational vehicle or emitting devices for emitting light or sound.

An HVAC air inlet housing for a vehicle includes an air inlet housing having a top portion and a bottom portion. A fresh air duct, to convey fresh air from an air inlet to a blower, is defined by the air inlet housing. A water inlet port, to connect to an evaporator drain port via a hose, is defined in the bottom portion. The hose is to convey water from the evaporator drain port to the water inlet port. A water tunnel is defined by the air inlet housing to convey water from the water inlet port to a sluice defined in the bottom portion. The sluice is to convey water from the water tunnel to a sump defined in the bottom portion. A sump drain port is defined in the air inlet housing bottom portion in fluid communication with the sump to drain water from the sump.

A vehicle HVAC system including a heat pump system. The heat pumps system including a refrigerant module mounting manifold, the manifold including a first plate and a second plate. The first plate and the second plate are configured to couple together such that together they define a plurality of channels for directing the flow of refrigerant through the heat pump system. One or more auxiliary modules are fluidly coupled to the refrigerant module mounting manifold.

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.

An air conditioning case defines a warm air passage, a cool air passage, a first space, and a second space therein. The cool air passage is in communication with the first space. The warm air passage is in communication with the first space. The second space is connected to the first space on a side of the first space away from the cool air passage. A case interior member including a tunnel member and a blade is arranged in the first space. The tunnel member includes an upstream-end forming portion and a downstream-end forming portion. The upstream-end forming portion is open to the warm air passage. The downstream-end forming portion is open in a direction away from the upstream-end forming portion. The blade extends from the downstream-end forming portion to both sides along a width direction, and guides the air from the tunnel channel to diffuse along the width direction.

A vehicle component housing, such as for an air filtration assembly, includes a first shell having a mount defining a retention feature, and a second shell having a flange. A fastener has a hooked region rotatably supported by the mount and configured to selectively mate with the retention feature to retain the fastener in a disengaged position. The fastener has a locking member configured to mate with the flange to retain the fastener in an engaged position. The fastener may be a spring clip fastener.

A first case member of a blower unit has a first communication passage communicating with an air intake side of a blower. A second case member of a temperature adjustment unit has a second communication passage communicating with a condensed water discharge portion through which condensed water is discharged. The respective case members are joined with each other in a state where a portion forming the first communication passage and a portion forming the second communication passage face each other. The portion of the first communication passage includes a drain portion having a groove shape and configured to discharge water in the first communicating passage. The portion of the second communication passage includes a drain receiving portion having a groove shape, communicating with the first communication passage and receiving the water discharged from the drain portion.
