Problems solved by technology

In the aforementioned vehicles there is a problem with regard to the heating and air conditioning of the passenger compartment: said vehicle type does not generate enough waste heat to heat the vehicle cabin in winter according to thermal comfort requirements
[0010] A disadvantage of the above-mentioned solutions according to the prior art is that the air for the tempering and cooling of the entire, usually relatively large, vehicle cabin is usually temperature-treated in the front part of the vehicle
The central temperature treatment of the air and its decentralized distribution consumes a lot of energy and the system is often underpowered

Embodiment Construction

[0046] exist figure 1 In principle, a vehicle 1 as a bus is shown with a plurality of air-conditioning zones 2 , which are associated with seats. The air conditioning zone 2 is supplied with temperature-treated air via the air outlet 20 of the air mixing unit 4 . In the exemplary embodiment shown, the temperature-conditioned air is supplied by two air-conditioning units 3 into a double line formed by a cold air channel 5 and a hot air channel 6 . The cold air duct 5 has a waste air valve 8 at the end, and the hot air duct 6 is closed at the end by a waste air valve 7 .

[0047] In the vehicle 1 , an air conditioning area 2 to which temperature-treated air is supplied through an air outlet 20 provided in the roof of the vehicle 1 is formed according to the number of seats. The air-conditioning zone 2 has an additional floor space heater 9 in the lower region of the vehicle, the floor space, which heats the floor space in a targeted manner, for example as an infrared radiation...

Abstract

The invention relates to a multi-zone air conditioning system for vehicles (1) with several air conditioning zones (2), in particular for buses, characterized thereby that an air temperature control unit (3) is implemented to generate simultaneously warm air and cold air, wherein the cold air across a cold air duct (5) and the warm air across a warm air duct (6) extend separated from one another as a double conduit over the length of the vehicle (1) and that decentralized air mixing units (4) with at least one air outlet (20) are disposed along the double conduit and that the air outlets (20)are assigned to the air conditioning zones (2) of the vehicle (1).

Description

technical field [0001] The invention relates to a multi-zone air-conditioning system for a vehicle, the passenger compartment of which has a plurality of air-conditioning zones, which are to be selectively supplied with different air temperatures and air volume flows. Background technique [0002] The field of application of the invention lies in particular in air-conditioning systems for buses in which a plurality of seats to be possibly air-conditioned to different degrees are air-conditioned according to the individual requirements of the passengers. [0003] The invention is used in particular in electric vehicles and in hybrid vehicles with a combined electric drive and internal combustion engine drive, as well as in fuel cell vehicles and in highly efficient internal combustion engine driven vehicles with multiple air conditioning area. With regard to the heating and air conditioning of the passenger compartment in the aforementioned vehicles, there is the problem tha...
