A vehicle air conditioning device including a duct for supplying conditioned air from an air conditioner to occupants, in which the air conditioner executes heating, ventilation, and air conditioning (HVAC) in a vehicle compartment; and the duct is extended in a vehicle rear direction and is fixed to a floor carpet is provided.

Disclosed embodiments include an automotive heating, ventilation, and air-conditioning (HVAC) system (12) for an interior of a vehicle (10), comprising: an auxiliary HVAC system (32) that provides conditioned air to the interior, the auxiliary HVAC system including an auxiliary air conditioning device (50); a control module that operates the auxiliary HVAC system independently of the central HVAC system (30); and one or more sensors for detecting, calculating, or both when fog, ice, condensation, or a combination thereof are located on a window of an automobile; wherein the central HVAC system includes a central air conditioning device (40) that is separate from the auxiliary air conditioning device (50).

An HVAC system includes a primary HVAC unit and a supplemental heat exchanger. The primary HVAC unit is disposed within a passenger compartment of a motor vehicle and configured for at least one of heating and cooling a passenger compartment. The supplemental heat exchanger is spaced apart from the primary HVAC unit and also disposed within the passenger compartment of the motor vehicle. The supplemental heat exchanger is configured to supplement at least one of the heating and the cooling of the passenger compartment by the primary HVAC unit.

A transportation trailer having a moving floor including a plurality of reciprocating slats for loading/unloading materials into the trailer. The trailer includes a system for warming the moving floor when the materials transported in the trailer freeze on the slats in cold weather. Using the pre-existing hollow structure of the slats, a stream of hot fluid or a hot fluid pipe is run inside the slats for thawing the frozen materials for unloading the trailer. The hot fluid may be provided from a hot fluid source on board of the trailer, for thawing the frozen materials while the trailer is on its way to the unloading site, or may be provided separately at the unloading site.

A vehicle comprising, a passenger cabin, a door to the passenger cabin, and an air conditioning system is disclosed. The air conditioning system comprise a Peltier device, a blower for directing an airflow over a first side of the Peltier device and ducting for ducting air to the blower, the ducting comprising an inlet located on an underside of the door.

A method, for providing supplementary heat energy into a cabin of a work machine when a main heating system of the cabin is inactive, includes using an auxiliary heat source to impart heat to an auxiliary coolant stream. The main energy form powers a main heat source of the main heating system. Further, the method includes providing an auxiliary fluid circuit to fluidly couple the auxiliary heat source with one or more heat exchangers to supply the auxiliary coolant stream from the auxiliary heat source to the one or more heat exchangers for circulation therewithin. During the circulation of the auxiliary coolant stream within the one or more heat exchangers, the auxiliary coolant stream dissipates heat to an air flowing across the one or more heat exchangers and into the cabin to provide the supplementary heat energy into the cabin.

In vehicle air-conditioning devices including a refrigerant circuit having a compressor, an outdoor heat exchanger, an expansion device, and an indoor heat exchanger that are connected by refrigerant pipes to form a refrigeration cycle; an indoor air-sending device that supplies air to the indoor heat exchanger; and an outdoor air-sending device that supplies air to the outdoor heat exchanger, the refrigerant circuit is installed under the floor of a vehicle and uses carbon dioxide as the refrigerant.

A temperature adjustment system for a vehicle including a closed network of interconnected fluid pathways disposed in at least one of a headliner, a door, and an instrument panel of the vehicle. A fluid is disposed in the closed network. A fluid pump pushes the fluid through the closed network. The closed network is not open to an interior cabin of the vehicle and thermodynamically influences a cabin temperature of the vehicle.

An electric vehicle having a heat exchanger formed in an aerodynamic airfoil shape comprising one or more body panels disposed along an outer surface of the vehicle having one or more fluidic chambers or micro-channels. The heat exchanger is adapted to provide effective and highly efficient heat transfer, and also to provide substantially reduced or negligible contribution to the aerodynamic drag. The heat exchanger includes a supplemental heat exchange system wherein at least a portion of the heat exchange capacity is provided by an inner heat exchange surface of the heat exchanger exposed to an interstitial space within the vehicle. Airflow is forced, via a fan for example, from an aerodynamically-efficient inlet, over the inner heat exchange surface, and exhausted through an aerodynamically-efficient outlet, thereby providing a supplemental heat exchange system including substantially reduced or negligible contribution to the aerodynamic drag.
