Abstract: Architectures and techniques are presented that can facilitate improved design and function of certain air handler devices. Architectures directed to an improved air handler device can be designed to improve temperature control demands such as, e.g., concurrently heat and cool air and reducing device dimensions (e.g., size, weight) that can reduce costs and mitigate shipping and installation difficulties. Architectures directed to U-bend structures can further reduce footprint on leasable space and provide improved acoustics, service access, and reduced energy consumption and infrastructure costs.

The internal lining system comprises construction elements, that are arranged in a pattern, such that the joints between the construction elements in the pattern at the flue gas side of the internal lining system are inclined at an angle ? of at least 5 degrees from horizontal.

Abstract: A passenger transport vehicle, such as a rail vehicle, has at least one sanitary module and at least one fan for conveying waste air from the sanitary module. A control unit controls the volumetric flow of waste air from the sanitary module. The control unit is formed for at least two volumetric flows of waste air, which differ from one another and differ from zero. The volumetric flows are conveyed by the at least one fan, at least on the basis of a state of the sanitary module.

Abstract: An energy efficient and quiet air cooling system for a building structure is provided. The air cooling system includes an evaporator system mounted in the wall of the building, a remotely mounted fan, an air intake, and a sound and heat insulating duct. The fan is mounted in the attic and configured to draw air from the living area of the building through the sound insulating duct with sufficient power to create a negative static pressure in the living area. The negative static pressure in turn causes outside air to flow through the evaporator system which removes heat from the outside air. The cooled air is in turn drawn into the building and pulled into the attic through the duct and expelled through the attic. The fan expels warm air into the attic, creating a positive pressure environment which causes the warm air to be expelled from the attic through natural vents.

Abstract: A pressure relief vent assembly that defines a plurality of enlarged water collection pockets and a plurality of water passage recesses that enable water to move between the water collection pockets and to be more evenly distributed relative to and in the respective water collection pockets, and thus is configured to inhibit water from entering an enclosed area through the pressure relief vent assembly.

Abstract: A vehicle system includes: a blower configured to draw air from within a passenger cabin of a vehicle through an inlet; a binding agent source configured to flow a binding agent into the air; and a sensor disposed downstream of the binding agent source in the direction of airflow, the sensor configured to determine an amount of smoke in the air from within the passenger cabin based on a measured characteristic of particulate at the sensor and a predetermined characteristic of the binding agent.

Abstract: Methods and systems are provided for heat sanitizing a vehicle. In one example, a method may include, while receiving power from an external power source and responsive to receiving a request for cleaning an interior of a vehicle, operating an electric heater of a heating, ventilation, and air-conditioning (HVAC) system to heat the interior above an upper threshold temperature for a first threshold duration using the power received from the external power source. In this way, the HVAC system may be advantageously used to expose the vehicle interior to temperatures that kill or inactive microbes while vehicle battery power and fuel are conserved by using power supplied from the external power source.

Abstract: An air-conditioning register includes: a movable fin; an operation knob; and a transmission mechanism. A load generating mechanism is provided in a middle of a force transmission path in the transmission mechanism. The load generating mechanism includes a pressure receiving portion, a pressing member, and a spring. The pressure receiving portion has a pressure receiving surface. The pressing member rotates with respect to the pressure receiving portion as the operation knob rotates. The spring generates a load between the pressing member and the pressure receiving portion by urging the pressing member toward a side approaching the pressure receiving surface and pressing the pressing member against the pressure receiving surface. The pressing member and the pressure receiving portion are each formed of a hard resin material, and the pressing member is directly in contact with the pressure receiving surface to generate the load.

Abstract: A module air curtain and recirculation system that can be incorporated into various tables and workstations that provides 1) an effective air curtain between individuals, 2) a reduction of harmful viruses and 3) the ability for two or more people to be in close proximity without having to wear personal protective equipment such as face masks. The apparatus for indoor air filtration and conditioning creates an air curtain between and around people. The device captures aerosolized droplets expelled from occupants and recirculates cleaned air to operate the air curtain while greatly increasing effective air changes per hour in spaces it is employed. While portable room air purifiers are used to improve the air quality of indoor spaces and reduce particles, allergens, and viruses, they do little to stop the person-to-person transmission of viruses. This device solves these deficiencies.
