Abstract: An air distribution system for use in a cargo delivery vehicle. The air distribution system includes a compressor, a condenser, a plurality of tubes, an air distribution unit, and a mounting system for mounting the air distribution unit to the roof of the cargo delivery vehicle. The air distribution unit includes a unit body, a vent hood, and a vent plate. The unit body includes a fan and a plurality of tubes. The vent plate includes at least one vent opening.

Abstract: A military vehicle air conditioning system has one or more compressors, condensers, and evaporators. The evaporators are spaced apart from each other at the front and rear of the vehicle. An interior air distribution plenum is vertically flush with a lower edge of the windshield, has a single vent for the driver, and a large clearance between the plenum and the steering wheel of the vehicle. The front evaporator is adjacent the front passenger footwell and equipped with a renewable filter. The condenser is inside a rear storage compartment, and fans force air into the compartment through vents in the door, through the coils of the condenser, and then exhaust the heated air from the compartment. The fans are intermittently reversed to purge dust and debris circulated during this process.

Abstract: A system, method, and apparatus for the integrated cooling of a vehicle and the personal climate systems worn by its occupants allows the components of the vehicle's refrigeration system to provide simultaneous cooling for both the vehicle and the occupants. A portion of the refrigerant circulated through the refrigeration system is redirected to a heat exchanger that chills the fluid circulated through the personal climate systems.

Abstract: A system for distributing air flow in an automotive ventilation system is disclosed. A blower is attached to a plenum assembly having multiple distribution chambers for distributing the air flow to different parts of the vehicle. A single duct channel is mounted inside the plenum between the blower and the chambers. Only the channel is pivoted to distribute the air flow to the various chambers. The system is installed in an automobile vehicle to direct air flow to, for example, the windshield, the dashboard vents, and the floor. The channel has first, second, and third positions such that it is substantially aligned with the first, second, and third chambers. The channel also has alternate positions wherein the air flow is distributed to more than one chamber at the same time.

Abstract: A heating and air-conditioning system allows heating and cooling of a vehicle while the primary engine of the vehicle not operating. The auxiliary engine has an electrical generating device for generating electricity. A radiator is connected to the auxiliary engine for receiving engine coolant. A heater element is in communication with the radiator for receiving part of the coolant. A fan powered by the electrical generating device discharges air through the heater element and into the vehicle. The auxiliary engine also powers an air-conditioning unit for supplying cool air. An electrical motor drives a pump for pumping an engine lubricant to and from the auxiliary engine. An oil filter treats the lubricant.
