A roof top air conditioner unit for a vehicle, in particular a recreational vehicle, wherein the roof top air conditioner at least in part is made of expanded polypropylene (EPP). At least one stabilizing and/or connecting element of the roof top air conditioner unit is mold in the section of the roof top air conditioner unit made of EPP. Furthermore, the present invention refers to a method for producing, assembling and installing such roof top air conditioner units and a vehicle having such a roof top air conditioner assembly.

The invention relates to a housing connecting device for connecting two housing sections or housing modules of a ventilation or air-conditioning system to each other, with at least in each case two first connecting elements (1) which are fastened to the operating and rear side of a first housing section or of a first housing module, with in each case at least one pawl (3), with at least in each case two second connecting elements (2) which are fastened to the operating and rear side of an adjacent second housing section or of an adjacent second housing module and each have one latching tooth (Z1) or two latching teeth (Z1, Z2) for preliminary latching and final latching of the pawl, wherein the connecting elements are attached either on the outer side or inner side of the housing sections or housing modules.

An air conditioning module, which can perform cooling and heating through a single module, which is capable of being compact-sized, which can prevent problems caused by condensate water because the condensate water can be easily discharged out, and which can control all of two doors for heating and cooling by actuating means.

A heating, ventilation, and air conditioning (HVAC) case for an HVAC assembly. The HVAC case includes a fastener for coupling a first portion of the HVAC case to a second portion of the HVAC case. A clip of the fastener is included with the first portion of the HVAC case. A retention member of the fastener is included with the second portion of the HVAC case. Cooperation between the clip and the retention member couples the first portion of the HVAC case and the second portion of the HVAC case together.

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.

An HVAC system for a vehicle includes a housing, an evaporator disposed in the housing, and a heater disposed in the housing. The HVAC system further includes a bypass opening defined between an upper end of the evaporator and an upper end of the heater and an intermediate chamber defined by the evaporator, the heater, the housing, and the bypass opening. The HVAC system further includes an upper outlet passage configured to direct air from the HVAC system into a passenger compartment of a vehicle. The evaporator is configured to output a first stream of air into the intermediate chamber and the HVAC system is configured to operate in a first operating condition in which a first portion of the first stream of air will pass through the heater and a second portion of the first stream will bypass the heater by passing from the intermediate chamber through the bypass opening and into the upper outlet passage.

An air handling system for a vehicle comprises a conditioning section for controlling a temperature of a flow of air, a mixing section disposed downstream of the conditioning section with respect to a direction of the flow of the air, and a delivery section disposed downstream of the mixing section with respect to the direction of the flow of the air. The delivery section includes a first chamber, a second chamber, and a third chamber. A dividing plate separates each of the second chamber and the third chamber into a first side portion to a first side of the dividing plate and a second side portion to an opposing second side of the dividing plate. The second side portion of the third chamber is configured to primarily direct the flow of the air towards a rear seat area of the vehicle.

A housing assembly for an HVAC system, including: a casing with an air inlet and an air outlet, forming a first portion of an air conduit between the air inlet and the air outlet, the air conduit being configured to guide airflow between the air inlet and the air outlet; a removable cover, attached to the casing and forming a second portion of the air conduit. The casing and the removable cover form a filter slot with a filter volume, configured to receive a filter of complementary shape, the filter slot including four sidewalls for constraining the filter, an inlet aperture and an outlet aperture for allowing the airflow between the air inlet and the air outlet. The air conduit includes a guidance wall neighboring at least one of the filter slot sidewalls, the second portion of the air conduit including a part of the guidance wall.

The present invention relates to a vehicular air conditioning device and, more particularly, to a vehicular air conditioning device wherein delimitation walls, which delimit air passages inside an air conditioning case, are formed separately from the air conditioning case and are detachably assembled to left and right cases, respectively, such that the delimitation walls can be fabricated regardless of the mold removing direction during injection molding, making it possible to reduce the thickness and weight; this makes it possible to secure air passages, thereby improving air fluidity, and warm wind supply channels for supplying warm wind to a defrost vent can be integrally formed on the delimitation walls, making any structure for fixing the warm wind supply channels unnecessary; as a result, costs for materials and costs for mold processing can be reduced, and the warm wind supply channels can be freely positioned within the size of the partition walls, thereby facilitating performance improvement.

An outdoor unit for an air conditioner is provided, which includes a case, a plurality of path portions separated from each other in the case and having a same discharge port, electronic units arranged on the plurality of path portions, and an air circulator arranged on the discharge port of the plurality of path portions to compulsorily circulate air in the case to an outside of the case through the plurality of path portions of the case.
