  • Patent number: 10675949
    Abstract: An evaporator unit for a rooftop air-conditioning system of a vehicle may include a housing having two evaporators. Each evaporator may include a plurality of evaporation pipes running parallel to one another and parallel to a Z axis of the evaporators, a distributor and collector box running parallel to an X axis of the evaporator, and a diverting box running parallel to the X axis of the evaporator. The distributor and collector box may include an inlet connector for liquid refrigerant and an outlet connector for gaseous refrigerant that may be disposed adjacent to one another on a same face side of the distributor and collector box and in a Y axis of the evaporator. The two evaporators may be disposed on both sides of an intake chamber of the evaporator unit and may lay opposite one another in a transverse axis of the evaporator unit. The evaporators may be structurally identical.

  • Patent number: 10675942
    Abstract: A condenser unit for a roof-mounted air conditioning system may include a condenser having a plurality of condensation tubes. The longitudinal ends of the plurality of condensation tubes may be connected to a first and second collection tube of the condenser. A carrier may secure the condenser unit to a vehicle roof having a first support region assigned to the first collection tube to support the first collection tube and a second support region assigned to the second collection tube to support the second collection tube. A fan frame may define a flow duct leading from the condenser to a condenser blower. The fan frame may be secured to the carrier having a first retaining region assigned to the first collection tube and a second retaining region assigned to the second collection tube. The condenser may be held on the carrier via the fan frame.
