The present disclosure relates to a water drain arrangement for a body of a vehicle. The water drain arrangement includes a drain channel, a tubular feed-through device extending through a first opening of a first wall panel of the body and a second opening of a second wall panel of the body. The water drain arrangement includes a body shell-fixed sleeve extending through the first shell opening of the first wall panel and is coupled to the first wall panel in a fluid-tight manner. A first end of the feed-through device is inserted through a first end of the body shell-fixed sleeve and includes a drain extending through a second end of the feed-through device. A free end of the drain channel is held in a fluid-tight manner in a seat of the feed-through device, which is disposed at a second end of the feed-through device.

An air-conditioning system having a discharge device (10) for discharging condensed water from the air-conditioning system, wherein the discharge device has a piping system (2) for guiding the condensed water, wherein the discharge device has a regulating element (3) and the regulating element is configured as an open channel rotatable about a longitudinal axis (4) between a first rotational position and a second rotational position. The regulating element (3) is configured and arranged such that the regulating element guides the condensed water inside the piping system (2) in the first rotational position and establishes a continuous connection between a drip-off point for the condensed water and an outer area around the air-conditioning system in the second rotational position.

The invention relates to an electronic interface housing (6) of an electrical heating device (1) for heating an airflow passing through, the electronic interface housing (6) being configured to house electronic components for controlling at least one heating element (4) fitted to the electrical heating device (1), including at least one printed circuit board (44), the electronic interface housing (6) comprising at least one rib (56, 58) in contact with the printed circuit board (44) in a contact zone (54), characterized in that the printed circuit board (44) comprises at least one water drainage opening (82) in the contact zone (54).

The disclosed technology includes devices, systems, and methods for a battery-integrated heat pump system. The disclosed technology can include a heat pump system having an indoor heat exchanger coil, an outdoor heat exchanger coil, and a compressor. The disclosed technology can further include a third heat exchanger coil, a battery, and a pump configured to circulate a fluid through the third heat exchanger coil and the battery. The disclosed technology can be configured to manage the temperature of the battery by operating the pump to facilitate heat transfer between the refrigerant and the fluid to heat or cool the battery.

A vehicular air conditioning system includes an intake case having an indoor air inlet for introducing an indoor air present in a vehicle interior and an outdoor air inlet for introducing an outdoor air present outside a vehicle, an intake door installed in the intake case to selectively block one of the outdoor air inlet and the indoor air inlet while rotating about a rotation center shaft, and a water blocking part configured to block water flowing into the vehicle interior from the indoor air inlet of the intake case.

Air conditioning units each include an evaporator, a blower fan, a compressor that compresses a coolant, a condenser that causes heat exchange between the coolant and outside air, a coolant pipe that causes the coolant to circulate, and a spray nozzle that sprays water in a mist form to the outside air flowing to the condenser. The evaporator and the blower fan are provided in a ceiling portion of the vehicle, and the condenser and the spray nozzle are provided in a lower portion of the vehicle.

The invention relates to a method for controlling the recovery of water in a motor vehicle, in which method, to recover water in an air-conditioning system (12) of the motor vehicle, air is cooled to a temperature below its dew point, and the water dropping out as a result of the cooling is collected in a water container (13). During water recovery, the air-conditioning system (12) is controlled by means of a water recovery control device (11), wherein, to control the water recovery by means of the water recovery control device (11), the air-conditioning system (12) is adjusted on the basis of at least one parameter value which is detected by a detection unit (10) and transmitted to the water recovery control device (11).

An assembly for collecting and removing leaked refrigerant, in particular from an evaporator of an air conditioning system of a motor vehicle and/or from a periphery, provided for the refrigerant, of the evaporator with a housing part for the air-tight surrounding of at least one refrigerant connection and/or at least one section of a refrigerant line, and with a connection element, whereby the attachment element has at least one first attachment opening and a second attachment opening, whereby the first connection opening is fluidically connected to the housing part by a channel element and the second connection opening can be fluidically connected to an outlet channel opening into the surroundings such that the refrigerant leaked within the housing part can be fed into the first channel element and can be discharged into the surroundings via the connection element and the outlet channel.

In an interior air conditioning unit, a divided case is provided with a main water receiver, a main drain port, a side wall, a secondary drain port, a partition wall, a notch, a droplet reservoir, a path, and a tilted portion. The side wall, the secondary drain port, the notch, the droplet reservoir, the path, and the tilted portion are respectively located such that a condensate water flows out of the main water receiver and reaches the secondary drain port through the notch before a water surface of the condensate water reaches a fitting portion between the divided cases. According to the above-described configuration, the condensate water produced in the cooling heat exchanger can be certainly prevented from leaking through the fitting portion of the air conditioning case.

The present disclosure provides a casing for an air conditioning unit including a main body, a door, a passing defining member, and a drain channel. The main body includes a fresh-air passage and a recirculation-air passage. The recirculation-air passage is positioned below the fresh-air passage. The door selectively opens and closes a communication hole through which the fresh-air passage and the recirculation-air passage are in fluid communication with each other. The passage defining member is disposed upstream of the communication hole and defines a lower side of the fresh-air passage. The drain channel extends from the passage defining member to a space outside of the recirculation-air passage to discharge condensed water generated in the fresh-air passage.
