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 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.

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.
