The invention relates to a mobile machine, in particular a forestry machine, which has a chassis and a drive unit which has an internal combustion engine and at least one hydraulic pump driven by the internal combustion engine, which hydraulic pump supplies a hydraulic system with pressure medium. The internal combustion engine with the hydraulic pump is located in an engine compartment formed inside a hood-like housing. The machine no driver workplace for an operator and is in the form of a machine that can be remotely controlled by means of a remote control. Inside the hood-like-housing there is at least one storage compartment that can be heated by the waste heat of the drive unit.

A ventilation system for a vehicle can include a roll over protection system. The roll over protection system can include a bar. The ventilation system can have an air duct configured to selectively attach to and detach from the bar.

A method comprises the steps of using microcomputer circuitry and logic generating data format providing activation and deactivation of a portable air cooling unit and operating the blower fan at differing speeds optimizing and conserving the rate of expending pre-cooled refrigerant. First, deactivating the unit during periods when cooling is unnecessary. Using sensors, including proximity sensors, for sensing the data format of individuals. The logic upon detecting an individual within the predefined range generates data format activating the chilled air output and deactivating the unit upon not sensing objects. The data format associated with the objects, dimensional aspect of range and operations of the portable air cooling unit are stored in the memory. Additionally, the active coupling of the temperature sensors operates the fan at lower speeds when the outside temperature is within the cooler temperature setting spectrum. Alternatively, switches are provided for operating the portable air cooling units.

A vehicle includes a prime mover provided behind a front room and below a floor panel, a propeller shaft extending in front of the prime mover and below the floor panel in a front-rear direction and configured to transmit rotational power output from the prime mover, an air conditioner unit that is provided in the front room and through which a first refrigerant flows, a compressor driven by power of the prime mover and configured to compress the first refrigerant, and a first pipe that connects the air conditioner unit and the compressor and through which the first refrigerant flows. The floor panel is formed with a center tunnel portion formed by bending the floor panel upward in a convex shape. A space in which the propeller shaft is provided is formed below the center tunnel portion. The first pipe extends through the space in the front-rear direction.

A vehicle includes a body mounted with a chassis, the body having a passenger compartment, a seat in the passenger compartment for supporting an occupant in a sitting position, and a roll over protection structure for the passenger compartment. The roll over protection structure includes an inlet coupled in gaseous communication to an air source, an outlet coupled in gaseous communication to a vehicle occupant wearable, and an airflow pathway through the roll over protection structure coupling the inlet to the outlet in gaseous communication.

In an exemplary embodiment of the present disclosure, a mobility vehicle and a tent shares air-conditioned air through a duct so that the air-conditioned air produced in the mobility vehicle circulates through the duct and a temperature in an internal space of the tent is adjusted. Furthermore, in an apparatus and system for sharing air-conditioned air for a mobility vehicle, energy efficiency is improved as a loss of the air-conditioned air is minimized at the time of transmitting the air-conditioned air from the mobility vehicle to the tent.

A riding vehicle is provided with a downdraft fan assembly mounted on a vehicle roll bar for providing a flow of ambient air over the vehicle operator and a canopy carried by the fan assembly and providing solar and precipitation protection for the operator.

A system and method for cooling an open air vehicle is provided. The system comprises a housing mounted on the vehicle configured to hold a water tank and a water filter. The system further comprises a water pump and one or more air blowers coupled to the water pump. The system further comprises a battery configured to supply power to the water pump and the one or more air blowers. The method comprises storing water in a water tank the water tank positioned within a housing on the vehicle. The method further comprises powering a water pump, via a battery, and pumping water from the water pump out of one or misting tips. The method further comprises providing one or more air blowers that distributes cold air and water coming out the misting tips.

A ride-on vehicle, in particular a bicycle or a three-wheel vehicle, more in particular a purely electric or pedal assist bicycle or three-wheel vehicle, which includes an electrically-driven air conditioning unit is carried by the frame of the vehicle. An auxiliary supporting structure is connected to the frame of the vehicle , and in one example includes two rear uprights transversally spaced apart from each other, extending above the saddle, and continuing into two upper beams and then into two front uprights, whose lower ends are connected to a frame portion which extends in front of the handlebar. there An air guiding structure is associated to the auxiliary supporting structure and is in communication with an outlet of the air conditioning unit and has one or more outlets for the flow of conditioned air, which are configured for directing jets of conditioned air towards and/or around a body of a user.
