  • Patent number: 10363792
    Abstract: An air-conditioning system for conditioning air in a vehicle passenger compartment is configured to operate in a cooling system mode for cooling air to be supplied to the passenger compartment and in a heat pump mode for heating the same, and to operate in a reheating mode. The air-conditioning system includes a housing having a first flow channel and a second flow channel for guiding air to an air distribution system having discharge ports communicating with the passenger compartment, and a refrigerant circulation system having at least two heat exchangers. In this case, the first heat exchanger that operates as an evaporator regardless of operating modes is disposed in the first flow channel, and the second heat exchanger that operates as a condenser/gas cooler regardless of operating modes is disposed in the second flow channel.

  • Publication number: 20170217278
    Abstract: An air-conditioning system for conditioning air in a vehicle passenger compartment including a housing having a first flow channel and a second flow channel for guiding air, and a refrigerant circulation system having at least two heat exchangers. An air guide device is disposed between the evaporator and the passenger compartment in the first flow channel, and an air guide device is disposed between the condenser/gas cooler and the passenger compartment in the second flow channel. The air guide device disposed in the first flow channel consists of multiple parts such as at least two members, and the members are respectively assigned to air channels extending to the passenger compartment, are independently controllable, and are movable so as to open or close the respective air channels.
