CZ30130U1 - Independent air conditioning system of commercial vehicle cab - Google Patents

Description

Technical field

The technical solution relates to the air conditioning of the cab of a commercial vehicle, ensuring increased driver and operator comfort.

BACKGROUND OF THE INVENTION

In most cases, known commercial vehicle cabs (UTVs) do not contain air conditioning because of:

- insufficient power of the engine alternator required to power the electric air conditioning

- the unpreparedness of the internal combustion engine to fit another pulley, which is necessary to drive the compressor air-conditioning system and the unsuitability of modifying such internal combustion engines.

Currently, only a few UTV models equipped with air conditioning are available from the Polaris Brutus and Kubota RTV-X series. Both known air-conditioning solutions from Polaris and Kubota build on the engine, which is factory-ready for pulley installation, to drive the built-in air conditioning compressor

The disadvantage of the cab without air conditioning is the low comfort of the driver and passengers in the hot summer months, the disadvantage of the built-in air-conditioning driven by the engine of the vehicle is a significant reduction of the usable engine power and increased fuel consumption during air conditioning operation.

The essence of the technical solution

The disadvantages of the known air conditioning systems for commercial vehicles are largely eliminated by the independent air conditioning of the cab of a commercial vehicle according to the technical solution, which is characterized in that the independent air conditioning comprises a mobile power generator to which an electric air conditioning unit is connected to the electric conductor. attached to the rear of the vehicle, outside the cab.

In the case of using an electric air conditioner with a 220 V AC motor and a mobile power generator with an output voltage of 220 V and a frequency of 50 Hz AC, the jumper wires are connected directly to the mobile generator.

When using an electric air conditioner with an electric motor of 12 V or 24 V DC, the connecting conductors of the electric power to the mobile power generator shall be alternatively with an output voltage of 220 V and a frequency of 50Hz or 110 V and a frequency of 60 Hz. connected via a voltage converter.

Also, when using an electric air conditioner with a 220 V AC motor and a mobile power generator with 110 V output voltage and 60 Hz AC, the jumper wires must be connected to the mobile power generator via a voltage converter. From the point of view of the location of the electric air conditioning unit, it seems advantageous to mount it on the roof part of the vehicle cab.

The advantage of the technical solution is that the independent air conditioning is made up of individual interconnected separate components, which are additionally mounted on the vehicle and together fulfill the function for which they are intended.

Clarification of the drawing

An exemplary embodiment of an independent air conditioner cab of a commercial vehicle powered by a mobile power generator is shown in the drawing, wherein the figure is a perspective side elevation view of a commercial air conditioner vehicle.

Example of technical solution implementation

The utility vehicle according to the figure consists of wheels in contact with the ground, a driver and passenger cabin 7, a stowage compartment 8 and a drive unit. An electrical air conditioning unit 5 is mounted on the roof part 6 of the cab 7 and is connected to the roof part 6 by means of fastening means. The electric air conditioning unit 5 is optionally equipped with an electric motor for 12 V or 24 V DC or 220 V AC. The air conditioner 5 through the opening in the roof part 6 of the cab 7 injects cooled air drawn in from the environment into the cab.

The power required to power this electric air conditioner 5 is supplied from a mobile diesel or gasoline generator 1, alternatively with an output voltage of 220 V and a frequency of 50 Hz AC, or 110 V and a frequency of 60 Hz AC. This power generator 1 is detachably mounted in the storage compartment 8 at the rear of the vehicle, outside the cab.

If an electric air conditioner 5 with an electric motor of 12 V or 24 V direct current is used, the connecting conductors 2, 4 of the electric current to the mobile generator I must be alternatively with an output voltage of 220 V and a frequency of 50 Hz AC or 110 V and 60 Hz AC, connected via a voltage converter 3.

Also in the case of using an electric air conditioner 5 with a 220 V AC motor and a mobile power generator I, with a 110V output voltage and 60 Hz AC, the connecting wires 2, 4 of the electric power supply must be connected to the mobile power generator I via voltage converter 3.

When using an electric air conditioner 5 with an electric motor of 220 V AC and a mobile generator as well as electric power with an output voltage of 220 V and a frequency of 50 Hz AC, the jumper wires 2, 4 are connected directly to the mobile generator 1.
