A firefighting apparatus has a positive pressure ventilation system for impairing dust, dirt, and other debris from entering a storage compartment of the apparatus. The system can blow dust, dirt and debris out from the storage compartment if the same enters the compartment. The positive pressure ventilation system includes a blower assembly that supplies a positive flow of air to the storage compartment, such that the pressure within the storage compartments is greater than the environment, and air will egress from the storage compartment into the surrounding environment, rather than entering the storage compartment from the surrounding environment.

A collective NBC filtration system (FIG. 1A) for providing positive-pressure purified air to a plurality of subjects in a protected space, or in an environment which cannot be maintained at positive pressure, in conjunction with one or more facepiece fluidly connected to the NBC filtration system. The system comprises: A casing body [102] including a first section [136] defining an inner volume therein, and a second section [138] adjacent to the first section. The second section includes an inlet port [116], The first section has a larger cross-section than the second section, and forms a peripheral first ledge [142] surrounding the second section. At least one NBC filter accommodated in the inner volume. The at least one NBC filter is supported on the first ledge [142], A lid [104] including a central portion [154] and a second ledge [152] surrounding the central portion. The central portion [154] includes a plurality of outlet ports [118], which are sealable. The lid [104] is openable to provide access to the inner volume and is securely closeable to affix the at least one NBC filter therein the inner volume by the second ledge [152], The lid [104] and the at least one NBC filter define, when the lid is securely closed, an outlet compartment there between. The outlet compartment has about the same cross-section as the second section. A blower [108] housed within the second section. A suction port of the blower being fluidly coupled to the inlet port. The system is configured such that the second section [138] fluidly couples the inlet port [116] to at least one inlet of the respective at least one NBC filter, and, when the lid [104] is securely closed, the outlet compartment [302] fluidly couples at least one outlet of the respective at least one NBC filter to the one or more outlet ports [118] but is otherwise fluidly sealed, thereby preventing potentially contaminated air from entering the outlet compartment, except via the at least one NBC filter.

A technique for providing cooling in a firefighting vehicle leverages the availability of firefighting fluid for cooling the vehicle's components. By tapping into a conduit or manifold that receives firefighting fluid to be sprayed toward a fire, an amount of cooling fluid is drawn and directed through one or more liquid-to-liquid heat exchangers, for providing cooling of the vehicle's components.

An external automotive condenser and light assembly for mounting on a body of a vehicle, the condenser and light assembly includes a condenser housing having a top portion defining at least one top opening and a bottom portion defining at least one bottom opening. The condenser housing includes a front face so as to permit at least one warning light to be affixed thereto. The condenser housing includes a right face extending rearward from the front face. The condenser housing includes a left face extending rearward from the front face. At least one warning light is affixed to an exterior of the front face.

The present invention relates generally to an external condenser and light assembly and, more particularly, to an improved external air conditioning condenser and housing that is designed to additionally serve as a light assembly for an emergency vehicle. The condenser housing is mounted to the exterior of the emergency vehicle, which improves the performance of the emergency vehicle's air-conditioning system. The design of the condenser housing also allows it to serve as a light assembly on which emergency vehicle lights are mounted. The condenser housing and light assembly structure thereby provides for proper air conditioning functionality without occupying space on the exterior of the vehicle that would more preferably be occupied by emergency lighting.

A rescue vehicle (2) includes a chassis (4), a drive unit (6) fastened to the chassis (4) and a driver's cab (8), which is fastened to the chassis (4). The chassis (4) is arranged behind the driver's cab (8) in a longitudinal direction L of the rescue vehicle (2). The rescue cab (10) has a gas-tight configuration. The rescue cab (10) has at least one door (12) as an access to the interior (14) of the rescue cab (10). The rescue vehicle (2) has an air supply unit (16), which is configured to supply the interior (14) of the rescue cab (10) with breathing air.

A vehicle and its air-conditioning air distribution device for a vehicle turret rotatably mounted with respect to a body of the vehicle. This device includes at least one annular chute coaxial to the axis of rotation of the turret and including at least one first flow orifice, the chute having an annular opening which is concentric thereto, the chute receiving a closing ring which matches with the opening of the chute, the closing ring being rotatable with respect to the chute, and including at least one second air flow orifice, the chute being intended to be made integral with the body, respectively with the turret, while the closing ring is intended to be made integral with the turret, respectively with the body.

A device for distribution of conditioning air for vehicle turret comprises at least one air duct sheath, the sheath comprising a chute adapted to be made integral with the vehicle and a shutter adapted to be made integral with the turret. The sheath is the form of an arch of circle coaxial with the rotation axis of turret. The device comprises at least one duct in the form of an arch of circle having the same average radius as that of the sheath and able to slide with respect to the sheath between a closed position in which the duct connects one end of the sheath to another end of said sheath, or to another sheath, for continuity of airflow between the sheaths, and an open position in which the duct is slid within the sheath so as to leave a passage transverse to the sheath along a circular sector.

Vehicle climate control systems include heating, ventilating and air conditioning (HVAC) systems for adjusting the vehicle cabin temperature. The HVAC system can deliver heated or cooled air to the vehicle interior to achieve a desired temperature inside the vehicle cabin. Some vehicles are equipped with secondary comfort features, such as heated or cooled seats, for additionally addressing occupant comfort. These features are typically stand-alone devices that function separately from the HVAC system.

The disclosure describes a system and method for the environmental control of a vehicle having a cargo area and an environmentally controlled passenger area with a partition between the passenger area and the cargo area. The environmental control being directed and performed by an environmental control unit that can include one or more fans, a control module, a mounting plate, and a directional manifold to control the direction of the airflow. The environmental control unit can be installed using a method that includes attaching a fan unit to the mounting plate, connecting the fan unit to the control module, coupling to the fan unit and/or the control module to a power supply, and attaching a directional manifold to control the direction of airflow in or out of the fan unit.
