  • Patent number: 11192427
    Abstract: A drainage system for draining water from an air intake and from an air distribution housing of an air conditioning system into the environment. The drainage system including a drainage opening or the drainage of water into the environment, wherein the drainage opening is formed on a lower shell of the air distribution housing and is divided into a drainage area for water from the air intake housing on the one hand, and a drainage area for water from the air distribution housing on the other hand, and wherein the drainage area for water from the air intake housing is formed by the terminus of a separate duct for the drainage of water from the air intake. In this way, the reciprocal effect between the different pressure levels is avoided or reduced to the extent possible.

  • Patent number: 11095182
    Abstract: Sealing arrangement for guiding an electrical connection through a wall of a housing for a device for driving a compressor having an electrically conducting connecting element, guided through a conical passage aperture of the housing, which at least regionally is fully enclosed over the entire circumference by a sealing element. Sealing element is formed as a hollow truncated cone and disposed between a conical sealing facing of the connecting element and a boundary surface of the passage aperture sealing the connecting element against the housing. The connecting element is disposed having been guided through a connection passage of a receiving member for receiving a plug housing with a wall into the plug housing. A device for driving a compressor of a gaseous fluid with the sealing arrangement and a method for assembling the device and use of the device are disclosed.

  • Publication number: 20140331710
    Abstract: The invention relates to a compact vehicle HVAC system including an evaporator unit, a condenser unit, and a component unit, as well as a refrigerant circuit. The evaporator unit and the condenser unit each are provided with air-passed heat exchangers and a fan in a casing. Further circuit components are displaced within the component unit. The casings of the evaporator unit, the condenser unit, and the component unit advantageously establish a connected compact casing arrangement. The heat exchangers are displaced within the compact casing arrangement. The refrigerant circuit is established for a combined refrigeration plant and heat pump operation as well as an afterheating operation, whereby in the afterheating operational mode the heating power of the afterheater established as condenser/gas cooler and the cooling power of the evaporator are controllable independently of each other.
