Abstract
A rooftop-mounted air-conditioning installation, in particular for the roof of a bus, has at least having a condenser unit and an evaporator unit. It has an air-flow duct with at least one air intake opening and one air discharge opening. A heat exchanger and a radial fan are arranged in the air-flow duct between the air intake opening and the air discharge opening. An axis of rotation of a fan wheel of the radial fan is oriented parallel to an air flow main direction that extends through the air-flow duct from the at least one air intake opening through the heat exchanger to the radial fan.
Claims13
A rooftop air-conditioning installation, comprising,
- at least with one condenser unit and one evaporator unit, the evaporator unit including an air flow duct with at least one air intake opening and at least one air discharge opening, wherein a heat exchanger and a radial fan generating an air flow are arranged in the air flow duct between the air intake opening and the air discharge opening, and
- a rotational axle of a fan wheel of the radial fan is aligned parallel to a main air flow direction which extends through the air flow duct from the at least one air intake opening through the heat exchanger to the radial fan wherein the fan wheel comprises backwardly curved fan blades and an air conduction section comprises a curvature in an axial top view that corresponds in its direction to the curvature of the fan blades of the fan wheel, the fan wheel fan blades extend to an edge or below the air discharge opening so that air flows already obliquely partially in a determined direction.
