Air distribution box

The present embodiments relate to an air distribution apparatus for distributing conditioned airflow from a roof mounted air conditioner to the inside of a vehicle, which includes an inlet port adapted to receive the conditioned airflow from the roof mounted air conditioner. An outlet port, which is disposed adjacent to each longitudinal end of the apparatus, delivers conditioned airflow to the vehicle. An internal supply duct is adapted to evenly split the conditioned airflow to the outlet ports.

Air distribution apparatus

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.

Roof top air conditioner unit, methods for producing, assembling and installing the roof top air conditioner unit and vehicle with the roof top air conditioner unit

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.

Mobile air conditioner

A frame is provided and is adapted to be installed in an opening and between the external unit and the roof or wall and having locating elements on each of a first side and an opposite second side of the frame, the locating elements or projections being configured together to locate the frame in the opening and to locate the frame in the external unit. The locating elements in the frame are positioned so that if the opening is the first type, the frame is adapted to be installed with the first side facing the roof or wall, and if the opening is the second type, the frame is adapted to be installed with the first side facing the external unit.

Frame fitting arrangement for vehicle air conditioner

The invention provides an air-conditioner for maintaining a temperature of a conditioned space at or near a set temperature. The air-conditioner comprises at least one rotating or reciprocating element adapted to rotate or reciprocate at a variable frequency. The variable frequency including one or more nuisance frequencies at which vibration or noise within the air-conditioner or the conditioned space causes a nuisance. A processor programmed to control variation of the variable frequency in response to operational requirement. The processor is configured to operate the at least one rotating or reciprocating element so as to substantially exclude operation at the one or more nuisance frequencies.

Air-conditioner control

An air-conditioner, adapted to be fitted to a roof/wall of a vehicle, comprises: an external unit containing a compressor and at least one heat exchanger element and having air channels respectively for supplying conditioned air and for receiving return air through an opening in a roof or wall of the vehicle, the opening being either of two types of different sizes; a frame to be installed in the opening and between the external unit and the roof/wall and having locating elements, on each of two opposite sides of the frame, configured to locate the frame in the opening and to locate the frame in the external unit, wherein the frame is to be installed with the first side facing the roof or wall for the first type of opening and is to be installed with the first side facing the external unit for the second type of opening.
