A heating ventilation and air conditioning (HVAC) system may effectively provide and/or substantially maintain adjacent thermal zones that have different temperatures and/or humidities from one another. The HVAC system may include a duct network including zonal ducts each having a zonal duct exit configured to create aerodynamic profiles that result in a thermal zone. A thermal zone may be characterized by a volume having a temperature and/or humidity which may differ from an adjacent thermal zone, such that a temperature and/or humidity gradient exists at a thermal zone boundary between adjacent thermal zones, and such that diffusion of the temperature and/or humidity between the adjacent thermal zones is aerodynamically inhibited, or otherwise minimized.

A combination of a roof top air conditioning unit, the combination comprising a roof top unit, a roof, connection air ducts and an air distribution box, wherein the roof top unit is disposed on an outer wall surface of the roof, the roof top unit having a base pan provided with an air outlet; the air distribution box disposed on an inner wall surface of the roof, the air distribution box provided with an air inlet upper duct; the plurality of connection air ducts communicating the air outlet of the roof top unit with the air inlet upper duct of the air distribution box via the opening of the roof, characterized in that an adjustment portion for adjusting a roof thickness gap is provided around the air outlet of the base pan. This combination simplifies the complexity of assembly, such that the mounting process is simpler, and thus the cost is also reduced.

A railcar air conditioning duct according to one aspect which guides air fed from an air conditioner mounted on a railcar. The railcar includes: a duct wall forming an air flow passage which guides air in a car longitudinal direction; and a plurality of through holes lined up in the car longitudinal direction, the through holes being open at the duct wall as air outlet ports through which the air in the air flow passage is blown from the air flow passage toward a passenger room. A ratio of an opening area of one of the through holes to an area of one of a plurality of partial regions formed by dividing, in the car longitudinal direction, an inner surface of a lower wall portion such that in plan view, the regions contain the respective through holes falls within a range of 2.0% or more and 7.5% or less.

The method includes a controller monitoring and measuring energy parameters of the transport vehicle climate control system. The method also includes calculating energy utilization of the transport vehicle climate control system based on the energy parameters. Also, the method includes calculating energy costs of the transport vehicle climate control system based on the calculated energy utilization. Further, the method includes displaying the calculated energy utilization and the calculated energy costs of the transport climate control system on a user interface.

An air flow regulator for a railway vehicle is configured so that the rattling of bars can be prevented without using welding, an affixation member, etc. An intake grill is provided at an intake opening for sucking air from an interior of a railway vehicle. The intake grill includes a frame, bars, and a reinforcement capable of deforming the bars. The frame defines an outer edge of the intake opening. The bars are plate-shaped members spanned between portions of the frame to connect the portions to each other. The reinforcement elastically deforms the bars to generate reaction force therein.

A vehicle monitoring apparatus (300) transmits transmission data obtained from each appliance (200) and the amount of transmission data to a data processing apparatus (500). First, the data processing apparatus calculates the amount of used resources that is the amount of resources used in processing the transmission data, in the amount of resources of computer resources, on the basis of the amount of transmission data. Next, the data processing apparatus increases or decreases, to the amount of used resources, the amount of secured resources that is the amount of resources secured in the amount of resources of the computer resources. Then, the data processing apparatus processes the transmission data by using the amount of secured resources in the amount of resources of the computer resources.

A modular, roof-mounted air-conditioning system for a vehicle includes at least two similar air-conditioning modules for air-conditioning areas within the vehicle, wherein the air-conditioning modules are combined to form a functional assembly, and wherein the assembly can be installed on a roof of the vehicle.

The invention relates to a multi-zone air conditioning system for vehicles (1) with several air conditioning zones (2), in particular for buses, characterized thereby that an air temperature control unit (3) is implemented to generate simultaneously warm air and cold air, wherein the cold air across a cold air duct (5) and the warm air across a warm air duct (6) extend separated from one another as a double conduit over the length of the vehicle (1) and that decentralized air mixing units (4) with at least one air outlet (20) are disposed along the double conduit and that the air outlets (20) are assigned to the air conditioning zones (2) of the vehicle (1).
