A seal assembly of an air handling system includes a housing formed by a first housing portion coupled to a second housing portion. The first housing portion has a plurality of ribs formed in a waffle pattern. The housing receives a portion of the fluid conduits. A seal engages an outer surface of the housing and receives the fluid conduits.

An air conditioning apparatus for a vehicle includes an air conditioning case in which an cooling air cooled by a cooling device and a heating air heated by a heating device flow into a temperature adjustment space. In the air conditioning case, a humidity adjustment passage guides a part of the heating air to an adsorbent as an air desorbing moisture from the adsorbent, and guides a part of the cooling air to the adsorbent as an air having moisture to be adsorbed by the adsorbent. The temperature adjustment space and the humidity adjustment passage are provided downstream of the cooling device and the heating device. An air passage extending from the humidity adjustment passage to a humidification duct is provided with a mixing inhibitor that inhibits mixing of the heating air and the cooling air and mixing of a dehumidifying air and a humidifying air.

An air-conditioning system for a vehicle may include at least one of a condenser module including a condenser housing and a condenser, the condenser arranged in the condenser housing, and an air-conditioning module including an air-conditioning housing and an evaporator, the evaporator arranged in the air-conditioning housing. The air-conditioning system may also include a plastic support frame including a plurality of parts, the support frame configured to support at least one of the condenser module and the air-conditioning module, and to hold at least one of the condenser module and the air-conditioning module on a vehicle roof. The air-conditioning system may also include at least one detent housing connection. The air-conditioning system may also include at least one of at least one detent support connection and at least one plug-type support connection including a securing element.

A ventilation port is formed in a casing of an air conditioner for railway car use, and communicates with a passenger compartment to be air conditioned. An indoor heat exchanger housed in the casing performs heat exchange with air flowing in and out of the casing through the ventilation port. A return hole cover serving as a ventilation port cover has rigid portions that are rigid and bending portions that bend more easily than the rigid portions, and thus the return hole cover is transformable between a first form and a second form folded more compactly than the first form, the first form being a form in which the return hole cover is detachably fixed to the casing in a state in which the return hole cover covers the ventilation port from an interior of the casing.

A vehicle air-conditioning apparatus that includes a blower unit including a scroll casing including a first wall having an intake port, a second wall opposing the first wall, and a peripheral wall, and an impeller. The apparatus further includes a motor of the impeller, a blow-out flow channel, and a motor cooling air introduction chamber. The motor cooling air introduction chamber is in communication with the blow-out flow channel via an air intake port opening in the peripheral wall of a tongue portion facing the blow-out flow channel at a position more closer to the first wall side than an inner wall surface of the second wall. At least one airflow regulating rib facing the peripheral wall provided with the air intake port is provided, and the airflow regulating rib projects from the inner wall surface of the second wall and having a top portion in the blow-out flow channel.

The present invention relates to an air conditioner for a vehicle, in which a means for fixing a cable connecting device is disposed integrally with an air-conditioning case, thereby having an optimized installation location, keeping rigidity, achieving weight lightening, and enhancing assemblability. The air conditioner is to condition air in the interior of the vehicle by heating or cooling indoor air, and includes: a cable connecting device for connecting an actuating means of a controller of the vehicle to actuate a door inside an air-conditioning case with an actuating means of the air-conditioning case by a cable; and a cable fixing part for fixing the cable connecting device to the air-conditioning case.

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.

The present embodiments relate to an HVAC system which is externally mounted on a vertical surface of an RV, truck or bus. The desire is to eliminate, or at least substantially reduce, a potential leakage path wherein water may sit on an upper surface of a vehicle and due to seal degradation over long periods of time, may find a pathway in through the roof of the vehicle and to an interior thereof. By positioning the HVAC on a vertical surface, gravity works to move water downward and away from the HVAC system rather than allowing it to stagnate in an area around potential apertures through the outer skin or outer surface of the vehicle.

A pressure relief assembly includes a pressure relief device including a housing that defines at least one air passage chamber, and at least one flap secured within the air passage chamber(s). The pressure relief device is configured to securely couple to a component. A cover is secured to the pressure relief device. At least one impact-absorbing bumper is disposed between the pressure relief device and the cover. The impact-absorbing bumper(s) is configured to dampen impact energy and undesirable noise.

An air conditioner includes a blower device and a heat-exchange device. The blower device has a centrifugal fan and a first casing provided with an intake opening and a discharge opening. The heat-exchange device has a long heater element and a second casing provided with an introduction opening and an ejection opening. The second casing is configured such that a flow of air introduced into the interior of the second casing via the introduction opening spreads out in the lengthwise direction of the heater element.
