Battery powered hybrid reefers that use for their driving force, energy derived from the best-mix integrated combination of electrical power generated from an internal combustion engine generator, an electric grid, a wheel driven generator and at least one solar panel.

A dust reduction device for a vehicle includes an inlet aperture for receiving airflow created as a result of forward movement of the vehicle. The dust reduction device provides a primary airflow path leading from the inlet aperture to a vehicle opening, and a secondary airflow path leading from the inlet aperture to a ventilation exit. During forward movement of the vehicle, the primary airflow path is substantially blocked by airflow from the secondary airflow path such that airflow from the primary airflow path is provided to the vehicle opening and into the vehicle thereby minimising dust ingress in the vehicle.

This invention relates to a heater. A combustion air blower feeds combustion air to a burner device. The burner device burns a gas-air mixture from the combustion air and a fuel and serves for heating air. A circulating air blower discharges heated air from the heater. A control device acts on at least one component of the heater, wherein a night mode parameter set associated with an operation of the heater in a night mode and a default parameter set are stored in a data storage device. After an activation of the night mode, the control device accesses the night mode parameter set and uses the same for acting on the component. The night mode parameter set effects a reduction of background noise generated by the heater.

Disclosed is a transportation unit comprising: a plurality of roadway wheels including wheel, a plurality of continuously variable transmissions (CVTs) including a first CVT and a second CVT, the plurality of CVTs receiving rotational input from the wheel, and a generator that is rotationally driven by rotational output from the plurality of CVTs, and wherein each of the plurality of CVTs is engaged over one of a corresponding plurality of discrete wheel rotational speeds.

An air conditioning unit includes a conditioning chamber, a fan with a fan air input and a fan air output, and an evaporative unit. The fan and the evaporative unit are arranged in the conditioning chamber. The fan draws in entry air to enter the air conditioning unit, then through the evaporative unit, to condition the entry air to produce conditioned air. Within the conditioning chamber, the fan is positioned and configured such that at least 30% of an area of the fan air output are positioned above an average top surface of the evaporative unit, and that air from the at least 30% of the area of the fan air output is directed towards a wall of the conditioning chamber prior to being redirected downwards and through the evaporative unit.

Provided are techniques for thermally efficient route selection. A request is received for a route for a vehicle to travel from a first geographic location to a second geographic location. Route data is retrieved for each of a plurality of routes, where the route data includes, for each portion of each route at a given time and day, air temperature adjacent to a road surface. Vehicle data is retrieved for the vehicle, where the vehicle data includes a desired temperature of an item being carried and a desired inlet air temperature. The route from the first geographic location to the second geographic location is determined using the route data and the vehicle data, where the route is thermally efficient. The vehicle is directed along the route, where the route specifies a lane from a plurality of lanes of a road for each portion of the route.

A recreational vehicle heating system comprises: a heating medium heater, a hot water supply heat exchanger, a heating medium circuit including a pump and a waste heat exchanger, and a heating medium tank compartmented by vertical partitions configured to allow for the heating medium flow over the partitions from one compartment to another in a sequential order, the hot water supply heat exchanger being arranged in one of the tank compartments, while the other tank compartments are part of heating medium circuits each including a pump and a waste heat exchanger. The first tank compartment in said sequential order is connected, via a conduit, to the heating medium heater, while the last tank compartment in said sequential order is configured to allow for the heating medium flow over to the conduit for the heating medium transfer by a pump via the heater to the first compartment.

A transport refrigeration system is provided. The transport refrigeration system comprising: a vehicle having a refrigerated cargo space; a refrigeration unit in operative association with the refrigerated cargo space, the refrigeration unit providing conditioned air to the refrigerated cargo space; a first engine configured to power the refrigeration unit; a first exhaust passage fluidly connected to the first engine and configured to transport exhaust from the first engine; a second engine configured to power the vehicle; and a second exhaust passage fluidly connected to the second engine and configured to transport exhaust from second engine to a single exhaust exit; wherein the first exhaust passage fluidly connects to the second exhaust passage such that exhaust from the first engine is transported from the first exhaust passage to the single exhaust exit through the second exhaust passage.

An autonomous robotic vehicle includes a conveyance system, a securable compartment configured to autonomously lock and unlock, a customer identification reader, at least one processor, and a memory storing instructions which, when executed by the at least one processor, causes the autonomous robotic vehicle to, autonomously: travel to a destination location of a customer; capture, by the customer identification reader at the destination location, a customer identification object; determine that the captured customer identification object matches an identity of the customer; unlock the securable compartment based on the determination; capture, by the product identification reader, a product identifier; and accept a product to be returned by locking the securable compartment. The securable compartment contains a product identification reader.

The present invention relates to ventilation systems and solutions for caravan vehicles, sports campers of a teardrop caravan type and ventilation units for larger caravans and recreation vehicles. The ventilation system of the present invention is designed to draw air through the caravan or recreation vehicle during driving and to ventilate the whole caravan vehicle both below and above the floor interior.
