| 20080256968 | ROOF-TOP AIR-CONDITIONING SYSTEM FOR A VEHICLE, PARTICULARLY A BUS - A rooftop air-conditioner operating according to the cold vapor-compression principle using an internal coolant for a vehicle. The air-conditioner including a sequence made up of a high-pressure side heat exchanging device with an associated fan device, followed by an expansion device and an evaporation device that use the internal coolant. The vehicle including an internal channel arrangement to convey air to be conditioned, which exchanges heat with the evaporation device. The air-conditioner having a modular construction of a high-pressure side heat exchanging device with associated fan device in its own housing. The connections for coupling identical high-pressure heat exchanging device modules can be provided, prepared or designed, and the modules are designed for grid-like coupling of modules of identical output and/or modules of stepped output. | 10-23-2008 |
