An onboard air conditioning device wherein the heating capability of air conditioning is improved, and gas is prevented from flowing into the vehicle interior even in the unlikely event that gas is produced by a battery. In this device, one end of an air flow channel is connected to an air conditioning unit for blowing temperature-regulated air into a vehicle interior, and the other end opens into the vehicle interior. The air flow channel draws air into the vehicle interior from the opening, the intake air is passed through a battery and heated by heat exchange, and the air is then sent to the air conditioning unit. The air conditioning unit sends the air from the air flow channel to a sensible heat exchanger, and after this air undergoes heat exchange with air taken in from another channel, the air is exhausted out of the vehicle interior.

In an air conditioner system for a mobility device, some inside air communicates with an outdoor heat exchanger when outside air for indoor ventilation is introduced, thereby improving heat pump performance. That is, by allowing indoor cold air to communicate with the outdoor heat exchanger upon mixing the inside and outside air during indoor cooling and allowing indoor warm air to communicate with the outdoor heat exchanger upon mixing the inside and outside air during indoor heating, it is possible to increase the heat pump efficiency as the outdoor heat exchanger recovers the heat of the indoor air during indoor cooling and heating. In addition, introduced is an air conditioner system for a mobility device in which a structure is simplified as inside air may be selectively transmitted to an outdoor heat exchanger side only by applying a flow path structure and a valve.

A method for producing an exchanger element package for arrangement in an installation space on board a vehicle assigned to a passenger compartment and/or an engine bay, between inner walls of the installation space and an exchanger element to be installed in the installation space. The method includes providing an exchanger element; detecting inner dimensions of the installation space; detecting outer dimensions of the exchanger element; and providing a mold with a mold cavity which is delimited by an outer mold wall and an inner mold wall, wherein the shape of the outer mold wall is defined by the inner dimensions or inner wall regions of the installation space and the shape of the inner mold wall is defined by the outer dimensions or outer wall regions of the exchanger element.

An automated vehicle (AV) can include a data processing system housed in a cooling rack, and a thermal reduction system to provide cooling for the data processing system. The thermal reduction system can include a fluid pump to pump cooling fluid through the cooling rack, a cabin radiator to receive the cooling fluid and pump cabin air from the interior cabin of the AV to cool the cooling fluid, and a main radiator to receive the cooling fluid and pump outside air to further cool the cooling fluid. Additionally, the thermal reduction system can include a secondary cooling unit that includes a condenser, evaporator, and compressor pump to further cool the cooling fluid.

A thermal reduction system for an autonomous vehicle can include a fluid pump pumping cooling fluid through one or more fluid lines of a cooling rack to cool a data processing system of the autonomous vehicle. The thermal reduction system can further include a cabin radiator receiving the cooling fluid from the fluid pump. The cabin radiator can include an air pump forcing cabin air from an interior passenger cabin of the AV though the cabin radiator to cool the cooling fluid.

A water chamber (10) for a motor vehicle (1) having a wall (13, 20, 21) which defines a first interior (23). The water chamber (10) has at least one air inlet opening (9), through which air can flow into the first interior (23), and at least one air outlet opening (25), through which air can flow out of the first interior (23). A water outlet opening (17) is present that is suitable for removing water from the first interior (23). The water chamber (10) is designed as a heat exchanger, comprising a heat exchange element (13, 20, 21; 16), which is used to transfer thermal energy from exhaust air into the first interior (23). The water chamber also has a structure (8, 26, 27, 40; 8) that is used to direct exhaust air to the heat exchange element (13, 20, 21; 16).

The heating capacity particularly at low outside air temperatures in a vehicular air-conditioning unit that heats the vehicle interior by heat pump operation of a refrigerant circuit using a compressor is improved. During heating, a refrigerant discharged from a compressor 2 releases heat in a radiator 4 into the vehicle interior, and the refrigerant decompressed after the heat release in the radiator evaporates in at least one of an external heat exchanger 7 and a ventilation heat exchanger 24. During cooling, the refrigerant discharged from the compressor releases heat in the external heat exchanger, and the refrigerant decompressed after the heat release in the external heat exchanger evaporates in an internal heat exchanger 9 to absorb heat from the vehicle interior. The vehicular air-conditioning unit includes a hot gas cycle circuit 31 for decompressing a part of the refrigerant discharged from the compressor, and causing the decompressed part of the refrigerant to flow through the internal heat exchanger to release heat into the vehicle interior.

First circulation portions switch a flow of a heat transfer medium such that one of the heat transfer media for two systems selectively circulates through a radiator flow path or a first bypass flow path. Second circulation portions switch the flow of the heat transfer medium such that the heat transfer media for the two systems selectively circulate with respect to a second flow path group. The first circulation portions and the second circulation portions are adapted to switch the flow of the heat transfer medium so as to form a first circulation circuit for allowing the heat transfer medium to circulate among a first flow path group, the second flow path group, and a first pump, as well as a second circulation circuit for allowing the heat transfer medium to circulate among the first flow path group, the second flow path group, and a second pump.

Energy-saving method/system for heating and humidifying a building or car's saloon are disclosed. The method includesdrawing in an outside airstream,passing it via a dry channel and then, via a wet channel, in an opposite direction. Thereafter, the outside airstream is heated and directed to the building as supply air. An exhaust airstream from the building is introduced into a product channel. The wet channel is situated between the dry and product channels. The wet channel is in pairwise heat-exchange interactions with the wet and product channels. Water vapor, contained in the exhaust airstream, is condensed, discharged into the atmosphere at a temperature closed to the dew point. The outside airstream, passed along the wet channel, is transfer-heated and humidified by the exhaust airstream. Water from the product channel is used for wetting the wet channel. The system includes at least two membranes arranged between the channels.
